Nursing Elites

1. 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.

2. A newborn diagnosed with an omphalocele defect is admitted to the intensive care nursery. Which nursing action is appropriate based on the current data?

• A. Placing the newborn on a radiant warmer
• B. Placing the newborn in an open crib
• C. Preparing the newborn for phototherapy
• D. Preparing the newborn for bottle-feeding

Correct answer: A

Rationale: Placing the newborn on a radiant warmer is appropriate as it helps maintain the body temperature and prevent hypothermia in a newborn with an omphalocele defect. This is crucial for the infant's well-being and supports their physiological stability.

3. The renin-angiotensin-aldosterone system plays an important role in maintaining blood pressure. Which compound in this system is most powerful at raising blood pressure?

• A. Angiotensin I
• B. Angiotensin II
• C. Angiotensin III
• D. Renin

Correct answer: B

Rationale: Angiotensin II is the most potent compound in the renin-angiotensin-aldosterone system for raising blood pressure. It acts as a powerful vasoconstrictor, leading to increased systemic vascular resistance. Angiotensin II is formed from angiotensin I through the action of the angiotensin-converting enzyme. While renin initiates the cascade by converting angiotensinogen to angiotensin I, it is angiotensin II that exerts the strongest pressor effect.

4. A child has a brain tumor. Which of the following findings should the nurse expect?

• A. Decreased head circumference
• B. Frequent headaches
• C. Increased appetite
• D. Increased blood pressure

Correct answer: B

Rationale: Children with brain tumors commonly experience frequent headaches due to increased intracranial pressure. This pressure can result in pain and discomfort, leading to headaches as a common symptom. Other symptoms may include nausea, vomiting, changes in vision, and behavioral changes, but headaches are a prominent feature in children with brain tumors.

5. 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.
