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 child who weighs 25 kg is receiving IV ampicillin at a dose of 300 mg/kg/24 hours in equally divided doses every 4 hours. How many milligrams should the nurse administer to the child for each dose?
- A. 1875 mg
- B. 625 mg
- C. 2000 mg
- D. 1500 mg
Correct answer: A
Rationale: To calculate the correct dose for each administration, you first need to find the total daily dose: 300 mg/kg * 25 kg = 7500 mg/day. Since this total dose is divided into equally divided doses every 4 hours, there are 6 doses in 24 hours. Therefore, 7500 mg ÷ 6 doses = 1250 mg per dose. The nurse should administer 1250 mg every 4 hours, resulting in a total of 1875 mg for each dose in a 24-hour period. Choice A, 1875 mg, is the correct answer. Choice B, 625 mg, is incorrect as it does not consider the total daily dose and the frequency of administration. Choice C, 2000 mg, is incorrect as it is not the calculated dosage based on the given parameters. Choice D, 1500 mg, is also incorrect as it does not reflect the correct dosage calculation for each dose.
3. The nurse is conducting an admission assessment of an 11-month-old infant with CHF who is scheduled for repair of restenosis of coarction of the aorta that was repaired 4 days after birth. Findings include blood pressure higher in the arms than the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. What pathophysiologic mechanisms support these findings?
- A. The aortic semilunar valve obstructs blood flow into the systemic circulation
- B. The lumen of the aorta reduces the volume of the blood flow to the lower extremities
- C. The pulmonic valve prevents adequate blood volume into the pulmonary circulation
- D. An opening in the atrial septum causes a murmur due to a turbulent left-to-right shunt
Correct answer: B
Rationale: The correct answer is B. Coarctation of the aorta causes narrowing of the aorta, reducing blood flow to the lower extremities. This narrowing results in higher blood pressure in the arms compared to the lower extremities, along with stronger brachial pulses and slightly palpable femoral pulses. Choices A, C, and D are incorrect because they do not align with the pathophysiological mechanism of coarctation of the aorta, which specifically leads to reduced blood flow to the lower extremities.
4. A 3-year-old child with a high fever and sore throat is brought to the clinic. The nurse observes that the child is drooling and has difficulty swallowing. What is the nurse’s priority action?
- A. Administer antipyretic medication
- B. Prepare for emergency airway management
- C. Offer the child ice chips to suck on
- D. Assess the child’s hydration status
Correct answer: B
Rationale: In a 3-year-old child with drooling, difficulty swallowing, high fever, and sore throat, the nurse should prioritize preparing for emergency airway management. These signs may indicate epiglottitis, a condition that can quickly obstruct the airway, leading to respiratory distress and potentially fatal outcomes if not managed promptly. Administering antipyretic medication (Choice A) may be necessary later but is not the priority. Offering ice chips (Choice C) is contraindicated as the child has difficulty swallowing. Assessing hydration status (Choice D) is important but not the priority when the airway is at risk.
5. When caring for a 4-year-old child diagnosed with celiac disease, the parent asks about foods to avoid. Which response by the nurse is correct?
- A. Avoid all dairy products
- B. Avoid foods containing wheat, barley, and rye
- C. Avoid all foods high in sugar
- D. Avoid foods with artificial coloring
Correct answer: B
Rationale: Celiac disease is managed with a strict gluten-free diet, necessitating the avoidance of foods containing wheat, barley, and rye. Gluten is found in these grains and can trigger an immune response in individuals with celiac disease, leading to damage to the small intestine. Therefore, it is essential for individuals with celiac disease, including children, to carefully avoid gluten-containing foods to maintain their health and well-being.
