Nursing Elites

1. A child with croup has an increased PCO2, a decreased pH, and a normal HCO3 blood gas value. Which finding does the nurse report to the healthcare provider based on these data?

• A. Uncompensated metabolic alkalosis
• B. Uncompensated metabolic acidosis
• C. Uncompensated respiratory acidosis
• D. Uncompensated respiratory alkalosis

Correct answer: C

Rationale: The blood gas values indicate uncompensated respiratory acidosis. In respiratory acidosis, there is an increased PCO2, decreased pH, and a normal HCO3 level. This condition requires immediate attention to address the underlying respiratory problem causing the acidosis.

2. A nurse assesses a male patient who has developed gynecomastia while receiving treatment for peptic ulcers. Which medication from the patient’s history should the nurse recognize as a contributing factor?

• A. Amoxicillin (Amoxil)
• B. Cimetidine (Tagamet)
• C. Metronidazole (Flagyl)
• D. Omeprazole (Prilosec)

Correct answer: B

Rationale: Cimetidine binds to androgen receptors, producing receptor blockade, which can cause enlarged breast tissue, reduced libido, and impotence. All these effects reverse when dosing stops. Amoxicillin, metronidazole, and omeprazole are not associated with gynecomastia.

3. A patient is prescribed fluconazole (Diflucan) for a vaginal yeast infection. The nurse should be concerned if the patient is also taking which medication?

• A. Losartan (Cozaar)
• B. Simvastatin (Zocor)
• C. Lisinopril (Zestril)
• D. Hydrochlorothiazide (HCTZ)

Correct answer: B

Rationale: When fluconazole is taken with statins like simvastatin, it can increase the levels of the statin in the blood, potentially leading to adverse effects such as muscle pain and weakness. Therefore, the nurse should be concerned if the patient is taking simvastatin along with fluconazole.

4. At what age may an infant close their eyes to bright lights and show improved head control?

• A. 30-33 weeks after conception
• B. 34-36 weeks after conception
• C. Less than 30 weeks after conception
• D. 37-40 weeks after conception

Correct answer: A

Rationale: Around 30-33 weeks after conception, infants usually start closing their eyes in response to bright lights and exhibit enhanced head control. This developmental milestone indicates progress in their visual and motor abilities, reflecting the maturation of their neurological system. As preterm infants continue to grow and develop, they gradually acquire these skills, showcasing the natural progression of their sensory and motor functions.

5. A child is being treated for dehydration with intravenous fluids. The child currently weighs 13 kg and is estimated to have lost 7% of his normal body weight. The nurse is double-checking the IV rate the healthcare provider prescribed. The formula the healthcare provider used was for maintenance fluids: 1000 mL for 10 kg of body weight plus 50 mL for every kilogram over 10 for 24 hours. Replacement fluid is the percentage of lost body weight × 10 per kg of body weight. According to the calculation for maintenance plus replacement fluid, which hourly IV rate will the nurse implement for 24 hours?

• A. 88 mL/hr
• B. 86 mL/hr
• C. 81 mL/hr
• D. 83 mL/hr

Correct answer: B

Rationale: For 13 kg, the maintenance fluid is 1150 mL (1000 mL for first 10 kg + 3*50 mL for the remaining 3 kg). Replacement fluid is 910 mL (0.07 * 13000 mL). Total fluid is 2060 mL, divided by 24 hours is 86 mL/hr.
