Sickle cell disease and vaso-occlusive crises require specific pediatric nursing care the CPN tests. Practice the crisis, hydration, and complication scenarios below with full rationales.
Question 1
A 10-year-old with sickle cell vaso-occlusive crisis reports severe pain but has a normal heart rate and dry skin. How should the nurse interpret this presentation?
- A) Physiologic adaptation occurs during prolonged pain states.✓
- B) The child is likely exaggerating the pain level.
- C) Autonomic neuropathy prevents typical sympathetic stress responses.
- D) The current analgesic therapy provides adequate pain control.
Show rationale
When managing pediatric patients with conditions like a sickle cell vaso-occlusive crisis, it is vital to understand how the body responds to prolonged nociceptive input. Over time, the body undergoes physiologic adaptation, which means the sympathetic nervous system habituates to the stressor. As a result, classic acute pain indicators like tachycardia and diaphoresis often resolve, even when the child is still experiencing severe pain. Option A correctly identifies this phenomenon. Option B is incorrect because assuming a child is exaggerating pain contradicts the gold standard of relying on the patient self-report. Option C is incorrect because sickle cell disease does not typically cause rapid-onset autonomic neuropathy. Option D is incorrect because the child is actively reporting severe pain, meaning the current analgesic therapy is clearly not providing adequate pain control despite the normal vital signs.
Question 2
A 6-year-old with sickle cell anemia is receiving packed red blood cells. Ten minutes into the transfusion, the child reports lower back pain and develops tachycardia and hematuria.
- A) Stop the transfusion and infuse normal saline through new intravenous tubing.✓
- B) Stop the transfusion and flush the existing intravenous tubing with saline.
- C) Pause the transfusion and administer the prescribed as needed intravenous acetaminophen.
- D) Pause the transfusion and immediately notify the attending pediatric hematology provider.
Show rationale
The child's symptoms strongly suggest an acute hemolytic reaction, which is a medical emergency. You must immediately stop the transfusion to prevent further exposure. Disconnecting the blood and maintaining IV access with normal saline through new intravenous tubing is critical because flushing the existing tubing would push more incompatible blood into the child. Administering acetaminophen treats a simple febrile reaction but ignores the severe hemolytic signs. Simply pausing the transfusion to call the provider delays vital nursing interventions and fails to secure clean venous access for emergency medications.
Question 3
A 14-year-old with sickle cell vaso-occlusive crisis is admitted to the pediatric unit. The provider orders as-needed oral acetaminophen and codeine. The nurse notes the patient takes a home regimen of long-acting oral morphine. Which action represents appropriate pain advocacy?
- A) Request a patient-controlled intravenous analgesia order.✓
- B) Administer the oral medications and reassess pain.
- C) Suggest adding a scheduled oral nonsteroidal medication.
- D) Apply warm compresses and guide relaxation techniques.
Show rationale
Patients with a history of chronic opioid use develop opioid tolerance and require higher baseline doses to achieve comfort. Weak oral opioids will not manage severe vaso-occlusive crisis pain. Option A is the best advocacy step because a patient-controlled analgesia pump provides appropriate systemic relief for severe crisis pain. Option B ignores the patient's tolerance and severe pain state, leaving them under-treated. Option C is a helpful adjunct but insufficient as a primary intervention for this acute crisis. Option D provides comfort but fails to address the inadequate pharmacological order.
Question 4
A family is planning a vacation to a high-altitude mountain resort. They ask if any special precautions are needed for their 10-year-old daughter has sickle cell trait.
- A) Advise canceling the trip due to the high risk of severe vaso-occlusive crisis.
- B) Recommend encouraging frequent hydration and monitoring the child for left upper quadrant pain.✓
- C) Prescribe prophylactic daily hydroxyurea to prevent sickling during the high-altitude mountain vacation.
- D) Suggest administering a prophylactic blood transfusion before traveling to the high-altitude resort.
Show rationale
Exposure to low oxygen tension at high altitudes can occasionally provoke sickling in individuals with sickle cell trait, rarely leading to splenic infarction. Maintaining excellent hydration and monitoring for left upper quadrant pain (a key sign of splenic involvement) are the most appropriate preventative measures. Option A is an overreaction; travel to altitude is not strictly contraindicated, provided the family takes reasonable precautions. Options C and D represent aggressive medical treatments that are reserved exclusively for patients with active sickle cell disease, not those who merely carry the trait.
Question 5
An 8-year-old with sickle cell disease presents to the ED with bilateral leg pain rated 9/10. The child has a history of asthma and is currently afebrile. Which analgesic plan is most appropriate for this patient?
- A) Administer scheduled intravenous ketorolac and PRN oral ibuprofen.
- B) Provide scheduled oral codeine and PRN intravenous morphine.
- C) Administer scheduled intravenous meperidine and PRN oral acetaminophen.
- D) Initiate continuous intravenous morphine using patient-controlled analgesia therapy.✓
Show rationale
For severe vaso-occlusive pain, rapid initiation of strong parenteral opioids like intravenous morphine via PCA is the gold standard. Relying on NSAIDs is insufficient for 9/10 pain, and doubling them increases bleeding risk. Codeine is contraindicated in pediatrics due to unpredictable metabolism that can lead to toxicity. Meperidine is avoided in sickle cell management due to the high risk of normeperidine-induced seizures.
Question 6
You are coordinating care for a three-year-old with bacterial meningitis receiving IV antibiotics and a seven-year-old with sickle cell crisis requiring pain reassessment. An unlicensed assistive personnel (UAP) is available. How should you direct the care?
- A) Delegate the pain reassessment to the UAP while you administer the antibiotics.
- B) Assess the sickle cell patient's pain while the UAP measures their vitals.✓
- C) Ask the UAP to flush the meningitis patient's IV before the antibiotics.
- D) Administer the antibiotics first while the UAP evaluates the sickle cell pain.
Show rationale
Effective delegation requires matching the task to the provider's scope of practice while maintaining patient safety. Assessing a patient's pain level, especially during a sickle cell crisis, requires clinical judgment and must be performed by the registered nurse. Therefore, assessing the sickle cell patient's pain while the UAP measures vitals is the most appropriate action. You cannot delegate pain reassessment or evaluation to a UAP, making those options incorrect. While flushing an IV might be allowed for some licensed practical nurses, it is outside the scope of practice for a UAP. By retaining the assessment responsibilities and delegating standard vital signs, you efficiently manage multiple high-acuity patients without compromising safety or violating scope of practice guidelines.
Question 7
A couple, both identified as having sickle cell trait, ask the nurse practitioner about the risks for their future children. They already have one child with sickle cell disease and are concerned about the odds for their next pregnancy.
- A) A twenty-five percent chance of the disease exists for each subsequent pregnancy.✓
- B) A fifty percent chance of the disease exists for each subsequent pregnancy.
- C) A seventy-five percent chance of the disease exists for each subsequent pregnancy.
- D) A one hundred percent chance of the disease exists for each subsequent pregnancy.
Show rationale
Because sickle cell trait follows autosomal recessive inheritance, each pregnancy carries an independent 25% risk of having the disease, a 50% risk of having the trait, and a 25% chance of being completely unaffected. Having a previous child with the disease does not alter the mathematical probability for future pregnancies, making Option A the only accurate statement. Option B incorrectly states the probability for inheriting the trait rather than the disease. Options C and D represent fundamental misunderstandings of independent genetic probability and would provide inaccurate, distressing information to the parents.
Question 8
A 14-year-old with sickle cell disease on a high-dose morphine PCA for acute chest syndrome reports new-onset myoclonus and confusion. Respiratory rate 14, SpO₂ 97% on room air. The nurse suspects opioid-induced neurotoxicity. What is the best next step?
- A) Administer naloxone 0.1 mg/kg IV for myoclonus
- B) Discontinue PCA and switch to a fentanyl PCA
- C) Request a CT scan of the head to rule out stroke
- D) Reduce the morphine dose and add a non-opioid adjuvant✓
Show rationale
Opioid-induced neurotoxicity can present with myoclonus, confusion, and hyperalgesia, especially with high morphine doses in sickle cell disease. The appropriate response is to lower the morphine dose and incorporate multimodal analgesia, such as NSAIDs or acetaminophen, to manage pain while reducing opioid burden. Naloxone (A) is not indicated and could precipitate an acute pain crisis. Simply switching to fentanyl (B) without dose adjustment does not address the accumulation of toxic metabolites; a dose reduction is needed first. A CT scan (C) is unnecessary given the clear temporal relationship to morphine. Guidelines for sickle cell pain management emphasize multimodal strategies to minimize opioid side effects.
Question 9
A 9-year-old patient with a history of sickle cell disease requires a peripheral intravenous catheter placement. Which pain mitigation strategy is most appropriate for this specific patient presentation?
- A) Utilize a vapocoolant spray immediately prior to the needle insertion.
- B) Apply a vibrating cold device proximal to the planned insertion.
- C) Administer an oral sucrose solution two minutes before the insertion.
- D) Provide a topical lidocaine cream sixty minutes before the insertion.✓
Show rationale
Patients with sickle cell disease are highly susceptible to vaso-occlusive crises triggered by exposure to cold temperatures. Therefore, any cold-based pain mitigation strategies are strictly contraindicated. Option D is the safest and most effective choice, as topical lidocaine provides excellent local anesthesia without altering tissue temperature. Option A is incorrect because vapocoolant sprays drastically drop the local skin temperature, risking a sickling event. Option B is incorrect because the vibrating cold device also relies on a frozen ice pack, which poses the same cold exposure risk. Option C is incorrect because oral sucrose is only an effective pain mitigation strategy for infants up to twelve months of age, making it developmentally inappropriate and ineffective for a nine-year-old child.
Question 10
A nurse is caring for a 6-year-old with sickle cell crisis receiving morphine via a patient-controlled analgesia (PCA) pump. The nurse observes the mother pressing the button while the child is sleeping. Which action should the nurse take?
- A) Explain to the mother that only the patient may press it.✓
- B) Document the mother's action and assess the patient's current pain.
- C) Request a provider order to switch to nurse-controlled analgesia.
- D) Decrease the continuous basal rate to prevent respiratory depression.
Show rationale
The safest approach to PCA therapy is ensuring only the patient activates the demand dose, as their own sedation level naturally prevents overdose. When a parent presses the button for a sleeping child, this bypasses that safety mechanism and creates a high risk for opioid-induced respiratory depression. You should directly intervene and educate the mother to stop this unauthorized PCA by proxy. Documenting the action without intervening (option B) is unsafe because it allows a dangerous practice to continue. Requesting a switch to nurse-controlled analgesia (option C) is unnecessary unless the child is physically or cognitively unable to use the PCA themselves. Decreasing the basal rate (option D) does not address the immediate danger of the mother delivering inappropriate bolus doses.
Question 11
A 10-year-old with HbSS is admitted for a severe vaso-occlusive crisis. The patient is receiving intravenous morphine via PCA and maintenance IV fluids at 1.5 times the normal rate. The nurse notes a new mild cough and an oxygen saturation of 91% on room air. Which action is most appropriate?
- A) Administer a PRN dose of intravenous furosemide immediately.
- B) Decrease the intravenous fluid rate to maintenance levels.✓
- C) Discontinue the patient-controlled continuous intravenous morphine infusion immediately.
- D) Apply cold compresses directly to the primary pain sites.
Show rationale
Overhydration is a major risk factor for acute chest syndrome in sickle cell crisis. Decreasing the IV fluid rate addresses the early signs of pulmonary compromise like a new cough and borderline hypoxia. Giving furosemide is premature without clear signs of pulmonary edema. Discontinuing the PCA inappropriately stops pain management, which will likely worsen the crisis. Cold compresses cause vasoconstriction and worsen sickling, so they should always be avoided.
Question 12
A 16-year-old Black female with a vaso-occlusive crisis requests her PRN hydromorphone exactly every four hours. The nurse notes this frequent clock-watching behavior in the chart. How should the nurse proceed?
- A) Administer the medication as requested to maintain pain control.✓
- B) Delay the administration to prevent potential opioid use disorder.
- C) Request a psychology consult for suspected drug seeking behaviors.
- D) Substitute a non-opioid analgesic to evaluate her true response.
Show rationale
Patients with sickle cell disease often exhibit clock-watching because they are anticipating the return of severe pain. Unfortunately implicit bias frequently causes providers to mislabel this as drug-seeking behavior. Option A is correct because administering the analgesic on time prevents breakthrough pain and builds trust with the patient. Option B is incorrect as withholding medication based on bias leads to unnecessary suffering and worsens the pain crisis. Option C is incorrect because clock-watching in this context is a coping mechanism for under-treated pain rather than a psychiatric disorder. Option D is incorrect and unethical because substituting medications without an order or transparency violates trust and standards of care.
Question 13
A 13-year-old is admitted for a vaso-occlusive crisis, and the nurse is currently developing a pain management plan for the shift.
- A) Ask the teen to identify which distraction techniques work best for them.✓
- B) Implement a strict schedule for pain medication based on the provider orders.
- C) Consult the parents to determine the most effective pain interventions at home.
- D) Provide a list of approved coping strategies for the teen to review.
Show rationale
Asking the adolescent to identify their preferred distraction techniques directly involves them in the care plan, which respects their input and gives them a sense of control over their pain management. Option B is incorrect because relying solely on a strict schedule ignores the teen's subjective experience and misses an opportunity to incorporate their personal coping preferences. Option C is incorrect because consulting the parents bypasses the adolescent, who is developmentally capable of articulating what works best for their own body. Option D is incorrect because simply providing a list is a passive approach; it does not actively solicit the teen's input or foster a collaborative therapeutic relationship. Empowering adolescents to make choices improves clinical outcomes.
Question 14
During a bedside handoff using the I-PASS framework for a 10-year-old with sickle cell crisis, the oncoming nurse repeats back the pain management plan and asks a clarifying question about the PCA settings.
- A) Evaluating the illness severity for the upcoming shift.
- B) Providing the detailed patient summary to the family.
- C) Demonstrating synthesis of information by the receiving nurse.✓
- D) Formulating the specific action list for the shift.
Show rationale
The I-PASS handoff bundle includes Synthesis by receiver, where the oncoming clinician repeats back key information and asks clarifying questions to confirm mutual understanding. This active listening step ensures safety. It is not the illness severity assessment (A), the patient summary (B), or the action list (D), as those components are primarily structured and delivered by the off-going clinician to organize the report.
Question 15
A 14-year-old with sickle cell disease is admitted for a vaso-occlusive crisis. The patient reports a pain score of 8/10 despite scheduled IV opioids. How should the nurse best contribute to multidisciplinary rounds?
- A) Administering an additional dose of intravenous morphine prior to the multidisciplinary rounds starting.
- B) Advising the hematologist to transition the patient to oral pain medications for discharge.
- C) Advocating for a pain management consult and the addition of child life services.✓
- D) Recommending the immediate cessation of intravenous fluids to prevent acute pulmonary edema complications.
Show rationale
When a patient experiences unrelieved pain despite adherence to the current medical plan, the nurse must advocate for advanced interventions. Suggesting a pain management consult and child life services introduces both pharmacological expertise and non-pharmacological coping strategies, making option C the most comprehensive action. Option A is an intervention, not a contribution to the collaborative planning process of rounds. Option B is inappropriate because transitioning to oral medications is unsafe when the patient's pain is currently uncontrolled on IV opioids. Option D is incorrect as aggressive hydration is a cornerstone treatment for vaso-occlusive crises to prevent further sickling.
