1. A 7-year-old is admitted to the hospital with persistent vomiting, and a nasogastric tube attached to low intermittent suction is applied. Which finding is most important for the nurse to report to the healthcare provider?
- A. Gastric output of 100 mL in the last 8 hours.
- B. Shift intake of 640 mL IV fluids plus 30 mL PO ice chips.
- C. Serum potassium of 3.0 mEq/L.
- D. Serum pH of 7.45.
Correct answer: C
Rationale: A serum potassium level of 3.0 mEq/L is significantly low and indicates hypokalemia, which can lead to serious complications such as cardiac arrhythmias. Therefore, it is crucial for the nurse to report this finding promptly to the healthcare provider for immediate intervention. The other findings are not as critical in this situation. Gastric output of 100 mL in the last 8 hours may be expected in a patient with persistent vomiting. The shift intake of IV fluids and ice chips indicates fluid replacement, which is important but not as urgent as correcting electrolyte imbalances. A serum pH of 7.45 is within the normal range and does not indicate an immediate concern.
2. A mother brings her 3-week-old infant to the clinic because the baby vomits after eating and always seems hungry. Further assessment indicates that the infant’s vomiting is projectile, and the child seems listless. Which additional assessment finding indicates the possibility of a life-threatening complication?
- A. Irregular palpable pulse
- B. Hyperactive bowel sounds
- C. Underweight for age
- D. Crying without tears
Correct answer: D
Rationale: In this scenario, the infant presenting with vomiting, lethargy, and projectile vomiting indicates a potential serious condition. Crying without tears is a sign of dehydration, a critical condition that can lead to life-threatening complications in infants. Dehydration can rapidly worsen an infant's condition, making prompt intervention crucial to prevent further complications. Irregular palpable pulse (Choice A) could indicate a cardiovascular issue but is less immediately life-threatening in this context. Hyperactive bowel sounds (Choice B) are more indicative of gastrointestinal issues rather than a life-threatening complication. Underweight for age (Choice C) may be concerning for growth-related issues but does not directly indicate a life-threatening complication like dehydration does.
3. A 7-year-old child with a history of asthma presents to the clinic with shortness of breath and wheezing. The nurse notes that the child’s peak flow reading is in the red zone. What should the nurse do first?
- A. Administer a bronchodilator
- B. Reassess the peak flow reading
- C. Notify the healthcare provider
- D. Provide oxygen therapy
Correct answer: A
Rationale: When a child with asthma presents with shortness of breath and wheezing, and the peak flow reading is in the red zone, indicating severe airflow limitation, the priority intervention is to administer a bronchodilator. Bronchodilators help dilate the airways quickly, improving airflow and assisting with breathing. Reassessing the peak flow reading is important but not the first action to take in a severe asthma exacerbation. Notifying the healthcare provider can be done after initiating immediate treatment with a bronchodilator. Providing oxygen therapy may be needed in some cases, but addressing the airway constriction with a bronchodilator should come first to improve ventilation.
4. The nurse is preparing to administer an immunization to a 5-year-old child. The parent asks if the vaccine can be given in a different way because the child is afraid of needles. What is the nurse’s best response?
- A. We can apply a numbing cream before the injection
- B. There is no other way to administer this vaccine
- C. We can give the vaccine as a nasal spray
- D. We can skip the vaccine if the child is too afraid
Correct answer: C
Rationale: Administering the vaccine as a nasal spray provides an alternative method of delivery that avoids the use of needles, addressing the child's fear while ensuring immunization. Nasal sprays are effective for certain vaccines and can be a suitable option in this scenario. Choice A is not the best response as it only addresses pain management but does not eliminate the use of needles. Choice B is incorrect as there are alternative delivery methods like nasal sprays. Choice D is incorrect as skipping the vaccine would leave the child unprotected and is not a recommended course of action.
5. The healthcare provider is assessing an infant with pyloric stenosis. Which pathophysiological mechanism is the most likely consequence of this infant's clinical picture?
- A. Metabolic alkalosis.
- B. Respiratory acidosis.
- C. Metabolic acidosis.
- D. Respiratory alkalosis.
Correct answer: A
Rationale: Pyloric stenosis leads to obstruction at the outlet of the stomach, causing frequent vomiting and loss of stomach acids. This results in a loss of hydrochloric acid and hydrogen ions, leading to metabolic alkalosis due to an increase in serum bicarbonate levels. Therefore, the correct answer is metabolic alkalosis. Choice B, respiratory acidosis, is incorrect as it is not typically associated with pyloric stenosis. Choice C, metabolic acidosis, is incorrect because the loss of stomach acids in pyloric stenosis leads to metabolic alkalosis, not acidosis. Choice D, respiratory alkalosis, is also incorrect as it is not the usual consequence of pyloric stenosis.
