Gastroenteritis questions are really dehydration questions. These cover assessing fluid status in a child, oral rehydration therapy and why it beats clear fluids alone, the signs that mean this child needs IV fluids now, and the infection-control steps that stop it spreading through a household or unit.
Question 1
1 of 150. A 13-year-old adolescent develops acute onset of vomiting on Sunday evenings. The adolescent recently transitioned to a new middle school and reports eating lunch alone in the bathroom to avoid interacting with older peers.
- A) Initiate an immediate referral to a pediatric gastroenterology specialist for evaluation.
- B) Recommend a temporary switch to virtual learning to reduce peer conflict.
- C) Prescribe a daily antiemetic medication to prevent the Sunday evening symptoms.
- D) Screen for social anxiety disorder and collaborate on peer integration strategies.✓
💡 Key Takeaway
Somatic symptoms tied to school transitions often mask underlying social anxiety or peer-related distress.
Show rationale
The acute onset of vomiting specifically on Sunday evenings is a classic anticipatory somatic symptom linked to the upcoming school week. Coupled with the behavioral cue of eating lunch alone in the bathroom, this presentation strongly points toward a peer-related stressor rather than a primary gastrointestinal issue. Option D is correct because the provider must identify the root cause, which in this case is likely social anxiety disorder or bullying, and address it through targeted behavioral strategies and school support. Option A is incorrect because the clear psychosocial triggers make an immediate specialist referral unnecessary and overly medicalized. Option B is incorrect because switching to virtual learning promotes avoidance, which ultimately worsens social anxiety. Option C is incorrect because treating the vomiting with an antiemetic merely masks the symptom without addressing the underlying psychological distress driving the physical response.
Question 2
11 of 150. A nurse is conducting a home safety evaluation for a family with a crawling 9-month-old infant and a history of frequent babysitter use. The parents want to ensure caregivers are prepared for potential toxic exposures. Which action provides the most reliable safeguard?
- A) Ensure the babysitter knows how to induce vomiting if an accidental ingestion is suspected.
- B) Program the national Poison Control Center phone number into all household and caregiver cellphones.✓
- C) Provide the babysitter with a written list of all cleaning supplies stored in the house.
- D) Instruct the babysitter to immediately call the child's pediatrician if an ingestion occurs unexpectedly.
💡 Key Takeaway
Immediate access to the Poison Control Center number ensures caregivers receive prompt, expert guidance during toxic exposures.
Show rationale
Immediate access to the Poison Control Center (1-800-222-1222) is critical for timely, expert guidance during an exposure, making pre-programming the number the most reliable safeguard. Inducing vomiting is contraindicated and can cause further harm. Providing a list of cleaning supplies does not help the caregiver manage the actual emergency once an ingestion occurs. Calling the pediatrician delays specialized toxicological triage, as the pediatrician will likely redirect the caregiver to Poison Control or the emergency department.
Question 3
2 of 150. A 2-year-old recovering from sepsis is downgraded to the pediatric floor. The child has been NPO for four days and is now ordered to advance to a regular diet as tolerated. Which intervention is most critical for the floor nurse to implement?
- A) Provide a full regular meal immediately to promote healing.
- B) Offer small amounts of clear liquids and assess tolerance.✓
- C) Request a speech therapy consult for a swallowing evaluation.
- D) Administer intravenous fluids at twice the maintenance rate.
💡 Key Takeaway
Diet advancement after prolonged NPO status should be gradual to prevent gastrointestinal complications.
Show rationale
After prolonged bowel rest during critical illness, advancing the diet must be done gradually to prevent gastrointestinal distress or refeeding issues. Offering small amounts of clear liquids first allows the nurse to safely assess tolerance. Providing a full regular meal immediately risks vomiting and aspiration. A speech therapy consult is unnecessary unless there is a specific neurological or structural deficit. Increasing intravenous fluids contradicts the goal of transitioning to enteral intake.
Question 4
84 of 150. An 11-year-old patient who is strictly NPO for suspected appendicitis complains to the nurse of extreme thirst and dry mucous membranes. Which intervention should the nurse implement to address this finding?
- A) Offer small sips of water to quickly alleviate the thirst.
- B) Provide ice chips to safely moisten the dry oral mucosa.
- C) Increase the intravenous fluid rate as ordered by the providers.✓
- D) Administer oral rehydration solutions in very small carefully measured amounts.
💡 Key Takeaway
Dehydration in NPO appendicitis patients must be managed exclusively through intravenous fluids to maintain surgical safety.
Show rationale
When a patient who is strictly NPO for suspected appendicitis exhibits extreme thirst and dry mucous membranes, they are showing clear clinical signs of dehydration. The safest and most appropriate intervention is to increase the intravenous fluid rate to restore hydration without violating preoperative fasting guidelines. Offering small sips of water, providing ice chips, or administering oral rehydration solutions all violate the strict NPO status, which significantly increases the risk of dangerous pulmonary aspiration during the impending induction of general anesthesia.
Question 5
85 of 150. The nurse assigns a UAP to take vital signs on a stable 4-year-old admitted for dehydration. The nurse must ensure clear communication regarding this delegated task. Which instruction is most appropriate?
- A) Instruct the UAP to report heart rates over 120.✓
- B) Tell the UAP to report any abnormal vital signs.
- C) Ask the UAP to document the vitals before lunch.
- D) Request the UAP to evaluate the child's hydration status.
💡 Key Takeaway
Delegation communication must include specific, objective parameters for reporting rather than requiring UAPs to interpret data.
Show rationale
Providing a specific parameter like a heart rate over 120 ensures the UAP knows exactly when to notify the nurse, fulfilling the requirement for clear direction. Option B is incorrect because asking the UAP to determine what is "abnormal" requires clinical interpretation, which is beyond their scope. Option C is incorrect because it focuses only on documentation timing rather than patient safety and immediate reporting. Option D is incorrect because evaluating hydration status is a nursing assessment that cannot be delegated.
Question 6
10 of 150. A 9-month-old infant is evaluated for failure to thrive. The infant exhibits a significant loss of subcutaneous fat but displays a voracious appetite during the clinic feeding. Which action should the nurse prioritize?
- A) Evaluate the infant for underlying malabsorption syndromes.
- B) Assess the caregiver's formula preparation and feeding routines.✓
- C) Order a comprehensive metabolic panel and thyroid studies.
- D) Recommend immediate hospitalization for intravenous nutritional support.
💡 Key Takeaway
A voracious appetite in a malnourished infant points to inadequate caloric intake rather than organic disease.
Show rationale
A voracious appetite in a malnourished infant strongly suggests non-organic failure to thrive due to inadequate caloric intake, often related to neglect, poverty, or improper mixing of formula. Option B is correct because assessing how the caregiver prepares the formula directly evaluates for underfeeding or over-dilution. Options A and C focus on organic causes of malnutrition, which are much less likely given the infant's eager feeding behavior. Option D is premature; while the infant is malnourished, intravenous support is not indicated without first assessing the feeding practices, oral tolerance, and degree of dehydration.
Question 7
64 of 150. A 4-year-old with short bowel syndrome develops profuse, foul-smelling diarrhea after a prolonged course of clindamycin. The stool PCR is positive for *Clostridioides difficile*. The nurse is preparing to clean the patient's bedside commode and perform hand hygiene.
- A) Use alcohol hand rub and wipe the commode with bleach.
- B) Use soap and water and wipe the commode with bleach.✓
- C) Use soap and water and wipe the commode with alcohol.
- D) Use alcohol hand rub and wipe the commode with alcohol.
💡 Key Takeaway
C. diff requires handwashing with soap and water and environmental cleaning with a sporicidal bleach agent.
Show rationale
C. diff spores are highly resistant to alcohol, so you must use mechanical friction with soap and water to physically remove them from your hands. For environmental surfaces like a commode, only an EPA-registered sporicidal agent like bleach will effectively destroy the spores. Option B is correct because it pairs the right hand hygiene with the right environmental cleaner. Options A and D incorrectly use alcohol rub, which fails to kill spores. Option C correctly identifies soap and water but incorrectly suggests alcohol for the commode, which will leave infectious spores behind on the surface.
Question 8
85 of 150. A 16-year-old presents to the urgent care clinic with sudden high fever, vomiting, and a diffuse macular erythroderma. Her mother mentions the teen uses superabsorbent tampons overnight during her current menstrual period. Which action is the most appropriate?
- A) Reassure the patient this is a typical viral exanthem with menses.
- B) Remove the tampon immediately and initiate aggressive intravenous fluid resuscitation.✓
- C) Prescribe a topical corticosteroid cream to manage the diffuse macular rash.
- D) Advise changing tampons more frequently and discharge with oral antibiotic therapy.
💡 Key Takeaway
Toxic shock syndrome is a medical emergency requiring immediate source control and hemodynamic stabilization.
Show rationale
The combination of a diffuse macular erythroderma, high fever, and systemic symptoms in a teen who uses superabsorbent tampons overnight strongly suggests toxic shock syndrome. This is a life-threatening medical emergency requiring immediate removal of the source and rapid hemodynamic stabilization. Option B correctly prioritizes source control and intravenous fluid resuscitation to manage potential hypotensive shock. Option A dangerously dismisses a potentially fatal condition as a benign viral illness. Option C inappropriately treats a systemic, toxin-mediated rash with a localized topical therapy, ignoring the underlying systemic collapse. Option D is unsafe because toxic shock syndrome requires inpatient management, intravenous antibiotics, and close hemodynamic monitoring rather than routine outpatient care.
Question 9
100 of 150. A 9-month-old infant is brought to the emergency department with a 3-day history of rotavirus. The infant exhibits lethargy and minimal response to pain, mottled extremities, and absent tears. Heart rate is 185 bpm.
- A) Administer oral rehydration solution via a nasogastric tube continuously.
- B) Infuse an isotonic crystalloid bolus of 20 mL/kg intravenously.✓
- C) Provide maintenance intravenous fluids using five percent dextrose solution.
- D) Offer small, frequent sips of oral rehydration solution immediately.
💡 Key Takeaway
Severe dehydration with impending shock requires immediate intravenous fluid resuscitation with isotonic crystalloids.
Show rationale
The infant presents with severe dehydration and impending shock, evidenced by lethargy, tachycardia, and poor perfusion. In this scenario, rapid intravenous fluid resuscitation is required to restore intravascular volume. Option B is the correct intervention, utilizing an isotonic crystalloid like normal saline. Options A and D are incorrect because oral rehydration therapy is contraindicated in patients with altered mental status and severe hypovolemia due to aspiration risk and inadequate absorption. Option C is incorrect; dextrose solutions are used for maintenance, not rapid volume expansion.
Question 10
145 of 150. An 18-month-old toddler is experiencing postoperative nausea and vomiting following a hernia repair. The provider has prescribed intravenous promethazine for symptom relief. Which action should the nurse take?
- A) Administer the medication slowly over fifteen to twenty minutes.
- B) Dilute the medication with normal saline before intravenous delivery.
- C) Monitor the patient's respiratory rate continuously during the infusion.
- D) Request a prescription for an alternative antiemetic medication instead.✓
💡 Key Takeaway
Promethazine is absolutely contraindicated for children under two years old.
Show rationale
Promethazine carries a black box warning and is absolutely contraindicated in children under two years of age due to the risk of fatal respiratory depression. The nurse must advocate for patient safety by withholding the medication and requesting a safer alternative, such as ondansetron. Administering the medication slowly, diluting it with normal saline, or continuously monitoring the respiratory rate are all unsafe actions because they do not eliminate the severe, life-threatening risks associated with giving this specific drug to an infant or young toddler.
