This domain makes up 32% of your test, totaling 40 of the 125 scored items. You must evaluate clinical scenarios involving enteral feedings, intravenous site complications, and pain assessment. Mastering these core nursing interventions is essential for passing the Medical-Surgical Nursing Certification Board (MSNCB) exam.
Question 1
20 of 150. A patient is recovering in an intensive care step-down unit and requires a central venous catheter for prolonged antibiotic therapy. When planning the patient's routine daily hygiene practices, which approach is most effective for preventing bloodstream infections?
- A) Wash the patient daily using a mild antibacterial liquid soap.
- B) Bathe the patient daily using chlorhexidine gluconate impregnated bathing cloths.✓
- C) Cleanse the patient daily using warm tap water and lotion.
- D) Shower the patient daily using standard povidone iodine body wash.
💡 Key Takeaway
Daily bathing with chlorhexidine gluconate reduces skin bioburden and lowers the risk of central line infections.
Show rationale
Daily bathing with chlorhexidine gluconate is a strongly recommended evidence-based practice to reduce skin bioburden and prevent infections, particularly for vulnerable patients in an intensive care step-down unit. Option B correctly utilizes this specific antimicrobial agent, which leaves a protective residual effect on the skin. Option A uses standard antibacterial soap, which does not provide the same sustained antimicrobial activity. Option C offers no infection protection and is inadequate for a patient with a central line. Option D suggests povidone-iodine, which is sometimes used for surgical site preparation but is not the standard recommendation for routine daily whole-body bathing.
Question 2
24 of 150. An older adult patient has a Braden scale score of 9 and experiences frequent episodes of fecal incontinence. Which nursing diagnosis should the nurse formulate to directly address the National Patient Safety Goals?
- A) Impaired Physical Mobility related to prolonged strict bed rest
- B) Risk for Impaired Skin Integrity related to continuous excretions✓
- C) Deficient Nutritional Status related to inadequate daily oral intake
- D) Risk for Infection related to continuous infectious fecal exposure
💡 Key Takeaway
Formulating skin integrity diagnoses directly supports safety objectives for highly vulnerable, immobile, and incontinent patients.
Show rationale
Preventing pressure injury is a core patient safety objective that requires accurate diagnostic formulation. A very low Braden score combined with constant moisture from incontinence creates a perfect storm for skin breakdown, making "Risk for Impaired Skin Integrity" the priority. Impaired Physical Mobility (Option A) and Deficient Nutritional Status (Option C) are contributing factors to the low Braden score, but the skin integrity diagnosis directly targets the actual safety outcome we want to prevent. Risk for Infection (Option D) is a secondary concern that typically arises only after moisture-associated damage has already compromised the skin barrier.
Question 3
37 of 150. A patient with diabetic peripheral neuropathy is prescribed gabapentin. After three days of therapy, the patient reports no change in pain levels.
- A) Advise that pain relief typically requires several weeks of gradual dose titration.✓
- B) Instruct the patient to double the evening dose for a faster therapeutic response.
- C) Recommend the provider switch the medication to a tricyclic antidepressant for better results.
- D) Explain that the medication is primarily for seizures and may not relieve neuropathy.
💡 Key Takeaway
Gabapentin requires gradual dose titration over several weeks to achieve effective neuropathic pain relief.
Show rationale
Gabapentin requires gradual titration to minimize side effects like dizziness and somnolence, and it often takes several weeks to reach an effective dose for neuropathic pain. Option B is incorrect because patients should never self-adjust doses without provider orders. Option C is premature since three days is insufficient to determine the drug's efficacy. Option D is incorrect because while gabapentin is an anticonvulsant, it is widely considered a first-line adjuvant analgesic for neuropathy.
Question 4
17 of 150. A patient with right-sided lobar pneumonia reports pleuritic chest pain and an oxygen saturation of 89% on room air. Which positioning strategy should the nurse utilize to optimize both comfort and oxygenation?
- A) Position the patient on the right side using a wedge pillow.
- B) Place the patient on the left side with the head elevated.✓
- C) Maintain the patient in a supine position with the bed flat.
- D) Assist the patient into a high Fowler position leaning far forward.
💡 Key Takeaway
Placing the unaffected lung dependent optimizes ventilation-perfusion matching and improves oxygenation in unilateral pneumonia.
Show rationale
For a patient with unilateral pulmonary disease, placing the unaffected lung dependent (good lung down) optimizes ventilation-perfusion matching. Gravity directs more blood flow to the healthy left lung, improving oxygenation while simultaneously splinting the right side to reduce pleuritic pain. Option A places the affected lung down, which increases blood flow to the consolidated lung tissue and worsens hypoxia. Option C decreases functional residual capacity, increasing the work of breathing and exacerbating hypoxemia. Option D describes the tripod position, which is excellent for COPD exacerbations but does not leverage gravity to improve perfusion to the healthy lung in unilateral pneumonia.
Question 5
7 of 150. A nurse is preparing to administer an intravenous push medication through a patient's central venous catheter. Before attaching the medication syringe to the needleless connector, which action is required to adhere to infection prevention guidelines?
- A) Flush the catheter lumen with heparin before attaching the syringe.
- B) Wipe the needleless connector with sterile saline before medication use.
- C) Scrub the needleless connector with chlorhexidine for fifteen seconds prior.✓
- D) Replace the needleless connector before administering the intravenous push medication.
💡 Key Takeaway
Needleless connectors must be scrubbed with an appropriate antiseptic using active friction before every access.
Show rationale
Proper disinfection of the connector is a critical strategy to prevent intraluminal contamination. Guidelines require applying active friction with an appropriate antiseptic, such as chlorhexidine or alcohol, for at least fifteen seconds before accessing the line to administer an intravenous push medication. Option C correctly identifies this mechanical friction requirement. Option A ignores the necessary disinfection step entirely. Option B is incorrect because sterile saline lacks the antimicrobial properties needed to kill surface pathogens. Option D is unnecessary and actually increases the risk of introducing bacteria by repeatedly opening the closed catheter system.
Question 6
29 of 150. A nurse is caring for a patient with a high-alert medication infusing. The pump screen displays a malfunction error, and the nurse prepares to remove the tubing to load it into a new pump. Which action should the nurse take?
- A) Turn off the infusion pump completely before opening the door.
- B) Pause the infusion using the keypad before opening the door.
- C) Clamp the roller clamp on the tubing before opening the door.✓
- D) Disconnect the tubing from the patient before opening the door.
💡 Key Takeaway
Manually engage the roller clamp before removing IV tubing to prevent accidental medication free-flow.
Show rationale
When an infusion pump malfunctions, the internal anti-free-flow mechanisms may also be compromised. Manually closing the roller clamp before opening the pump door prevents the accidental free-flow of high-alert medications into the patient. Turning off or pausing the pump only stops the electronic motor; it does not physically occlude the tubing once the door is opened and tension is released. Disconnecting the tubing from the patient unnecessarily breaks the sterile system and increases the risk of infection and blood loss.
Question 7
34 of 150. During a thoracentesis, after 1,200 mL of pleural fluid removed, the patient suddenly reports feeling dizzy and chest tightness. Which action should the nurse take?
- A) Instruct the patient to perform the Valsalva maneuver immediately.
- B) Clamp the drainage tubing and assess the vital signs.✓
- C) Administer a rapid bolus of intravenous normal saline solution.
- D) Encourage the patient to take slow and deep breaths.
💡 Key Takeaway
Rapid removal of large volumes of pleural fluid can cause re-expansion pulmonary edema or cardiovascular collapse, requiring immediate cessation of drainage.
Show rationale
Removing more than 1,000 to 1,500 mL of pleural fluid at one time increases the risk of re-expansion pulmonary edema and hemodynamic instability. Dizziness and chest tightness indicate a severe fluid shift or vasovagal response. The nurse must immediately clamp the tubing to stop further drainage and assess vital signs. The Valsalva maneuver is used during chest tube removal, not for managing distress during a thoracentesis. Administering a saline bolus requires a provider's order and does not immediately halt the ongoing fluid shift. Deep breathing alone will not resolve the acute hemodynamic compromise caused by the rapid fluid removal.
Question 8
12 of 150. A patient is in the preoperative holding area for a right knee arthroscopy. The surgeon is delayed in traffic, and the circulating nurse notes an unmarked surgical site. The surgeon calls and requests the nurse to mark the site to save time.
- A) Mark the site after verifying the signed consent.
- B) Wait for the primary proceduralist to mark the site.✓
- C) Ask the awake patient to mark the surgical site.
- D) Proceed to the suite and mark the site there.
💡 Key Takeaway
The licensed independent practitioner performing the procedure must mark the surgical site.
Show rationale
According to the Universal Protocol, site marking must be performed by the licensed independent practitioner who is ultimately accountable for the procedure. Therefore, waiting for the proceduralist is the only correct action. The nurse cannot mark the site even if the consent is verified, making the first option incorrect. Asking the patient to mark the site is unsafe and violates protocol, eliminating the third option. Proceeding to the operating suite without a mark bypasses a critical safety checkpoint, making the final option incorrect. The mark must be made before the patient is moved to the location where the procedure will be performed.
Question 9
10 of 150. A Seventh-Day Adventist with chronic kidney disease is admitted to the unit and is prescribed a low-potassium vegetarian diet. Which action should the nurse prioritize to ensure safe nutritional management?
- A) Recommend increasing daily dairy intake to ensure adequate essential protein consumption.
- B) Encourage consumption of whole grains and mixed nuts for optimal renal health.
- C) Advise the patient to temporarily consume lean poultry during acute disease exacerbations.
- D) Collaborate with a dietitian to identify low-potassium plant-based protein food sources.✓
💡 Key Takeaway
Seventh-Day Adventists typically follow vegetarian diets, requiring careful planning when managing concurrent renal dietary restrictions.
Show rationale
A Seventh-Day Adventist faces a complex dietary challenge because their faith promotes a vegetarian diet, but many plant-based proteins are high in potassium and phosphorus, conflicting with renal restrictions. Option D is correct because collaborating with a dietitian ensures the patient receives protein sources that align with both their medical needs and religious dietary practices. Option A is incorrect because increasing dairy introduces excessive phosphorus and potassium. Option B is incorrect because whole grains and nuts are typically restricted on a renal diet. Option C is incorrect because asking a vegetarian to consume poultry violates their deeply held religious practices.
Question 10
30 of 150. A patient awaiting a bowel resection surgery has a history of severe peripheral arterial disease with an ankle-brachial index of 0.6. The provider orders mechanical prophylaxis with sequential compression devices. Which action should the nurse take?
- A) Apply the sequential compression devices to both lower extremities.
- B) Clarify the sequential compression device order with the surgeon.✓
- C) Place graduated compression stockings instead of the ordered devices.
- D) Elevate both lower extremities to promote optimal venous return.
💡 Key Takeaway
Mechanical compression prophylaxis is contraindicated in patients with severe peripheral arterial disease.
Show rationale
Sequential compression devices are contraindicated in patients with severe peripheral arterial disease because the external pressure can further compromise blood flow and worsen arterial ischemia. The nurse must clarify this order with the surgeon. Applying the devices to both extremities could cause tissue necrosis. Placing graduated compression stockings is equally contraindicated for the same ischemic risks. Elevating the lower extremities is inappropriate because it decreases arterial perfusion to the distal tissues, which exacerbates the patient's underlying arterial disease.
Question 11
15 of 150. A patient with severe expressive aphasia following a recent stroke is cognitively intact but cannot speak. The nurse notices frequent grimacing during repositioning. Which approach should the nurse use to assess the patient's pain?
- A) Administer analgesics and observe for immediate behavioral changes.
- B) Utilize the PAINAD tool to calculate pain scores.
- C) Provide a visual analog scale for patient pointing.✓
- D) Interview the family member regarding typical pain behaviors.
💡 Key Takeaway
Cognitively intact patients with expressive aphasia should be offered alternative methods for self-reporting pain.
Show rationale
The primary rule in pain assessment is that self-report is always the most reliable indicator, even when communication barriers exist. A patient with severe expressive aphasia cannot speak but often retains the cognitive ability to comprehend and indicate their needs. Option C is the correct choice because providing a visual analog scale allows the patient to point, facilitating a modified self-report. Option A is incorrect because an empiric analgesic trial is a last resort when all other assessment methods, including self-report and behavioral observation, have failed. Option B is incorrect because the PAINAD tool is for patients with cognitive impairment like dementia, not isolated expressive aphasia. Option D is incorrect because surrogate reporting from a family member is lower on the pain assessment hierarchy and should only be used if the patient is completely unable to self-report.
Question 12
26 of 150. While preparing a fentanyl transdermal patch for a patient with chronic pain, the nurse drops the unwrapped patch onto the contaminated floor. Which action is the most appropriate way to handle this situation?
- A) Pick up the patch, clean it with an alcohol wipe, and apply it carefully.
- B) Discard the dropped patch in the biohazard bag and document it as a waste.
- C) Fold the patch in half, waste it with a witness, and document the event.✓
- D) Leave the patch on the floor until the charge nurse arrives to witness it.
💡 Key Takeaway
Contaminated transdermal narcotics must be folded closed and wasted with a witness in a designated receptacle.
Show rationale
A dropped and contaminated fentanyl patch must be treated as unusable; the nurse should fold the adhesive sides together and waste it in a designated receptacle with a witness. Option A is incorrect because applying a contaminated patch introduces infection risk, and alcohol alters the drug delivery system. Option B is incorrect because discarding a controlled substance without a witness violates legal tracking requirements and enables diversion. Option D is incorrect because leaving a controlled substance unattended on the floor creates an immediate safety and diversion hazard for staff and patients.
Question 13
14 of 150. A patient with no prior opioid use is admitted with severe back pain. The provider prescribes a transdermal fentanyl patch to be applied every seventy-two hours alongside oral acetaminophen.
- A) Apply the patch to a clean hairless area.
- B) Contact the provider to question the fentanyl order.✓
- C) Place a warm heating pad over the patch.
- D) Monitor the patient's respiratory status every two hours.
💡 Key Takeaway
Transdermal fentanyl is contraindicated in opioid-naive patients due to the high risk of fatal respiratory depression.
Show rationale
Transdermal fentanyl is strictly indicated for patients who are opioid-tolerant because it delivers a potent, continuous dose that can cause fatal respiratory depression in naive individuals. Option B is the best action because the nurse must advocate for patient safety by halting an inappropriate prescription. Option A is a correct administration technique but ignores the critical safety contraindication. Option C is dangerous because heat increases medication absorption and toxicity risk. Option D is a standard safety measure but fails to prevent the administration of a contraindicated medication.
Question 14
35 of 150. During the pre-procedure verification process, the nurse notes the consent lists right knee replacement, but the daily schedule indicates left knee replacement. The patient is currently awake and oriented.
- A) Halt the process until the surgeon clarifies the discrepancy.✓
- B) Correct the schedule to match the signed consent form.
- C) Ask the patient which knee requires the surgical procedure.
- D) Proceed with the right knee based on the consent.
💡 Key Takeaway
Any discrepancy identified during pre-procedure verification requires a hard stop until the proceduralist resolves it.
Show rationale
The pre-procedure verification standard dictates that any discrepancy regarding the patient, procedure, or site must result in a hard stop until the primary proceduralist resolves the issue. Halting the process ensures patient safety. The nurse should never unilaterally alter the schedule based on the consent, as either document could be flawed, making the second option incorrect. While patient input is valuable, the patient alone cannot resolve a formal documentation conflict without the surgeon's validation, eliminating the third option. Proceeding based solely on the consent form is dangerous because the consent itself might contain the error, making the final option incorrect.
Question 15
11 of 150. A patient is preparing for a total hip arthroplasty discharge and is prescribed apixaban for thrombosis prophylaxis. The patient asks the nurse which over-the-counter pain medication is safest for mild muscle aches at home. Which instruction should the nurse provide?
- A) Advise the patient to use acetaminophen instead of ibuprofen.✓
- B) Instruct the patient to take ibuprofen with food daily.
- C) Recommend the patient alternate acetaminophen and naproxen every shift.
- D) Suggest the patient take aspirin for breakthrough joint pain.
💡 Key Takeaway
Patients taking direct oral anticoagulants should avoid NSAIDs to prevent severe gastrointestinal bleeding.
Show rationale
Apixaban is a direct oral anticoagulant used to prevent postoperative clots. Concurrent use of nonsteroidal anti-inflammatory drugs significantly increases the risk of severe gastrointestinal bleeding. The nurse should advise acetaminophen, which does not interfere with platelet function or coagulation. Instructing the patient to take ibuprofen daily, even with food, remains unsafe due to the compounded bleeding risk. Alternating acetaminophen with naproxen still exposes the patient to dangerous NSAID interactions. Suggesting aspirin for breakthrough pain is incorrect because aspirin irreversibly inhibits platelets, further magnifying the hemorrhage risk.
