Nursing Elites

1. A 6-month-old infant is prescribed digoxin for the treatment of congestive heart failure. Which observation by the practical nurse (PN) warrants immediate intervention for signs of digoxin toxicity?

• A. Apical heart rate of 60 beats/min
• B. Sweating across the forehead
• C. Poor sucking effort
• D. Respiratory rate of 30 breaths/min

Correct answer: A

Rationale: A heart rate of 60 beats/min for a 6-month-old infant warrants immediate intervention as it falls below the normal range. The normal heart rate for a 6-month-old is 80 to 150 beats/min when awake, and a rate of 70 beats/min while sleeping is considered within normal limits. Bradycardia (heart rate <60 beats/min) in infants can be a sign of digoxin toxicity, necessitating prompt evaluation and intervention to prevent adverse effects. Sweating across the forehead (Choice B) is a non-specific symptom and may not directly indicate digoxin toxicity. Poor sucking effort (Choice C) and a respiratory rate of 30 breaths/min (Choice D) are not typically associated with digoxin toxicity and do not require immediate intervention in the context of this question.

2. A client receiving enalapril reports a persistent dry cough. The nurse should explain that this side effect is related to which medication action?

• A. It reduces the production of angiotensin II.
• B. It increases the production of angiotensin II.
• C. It causes increased production of bradykinin.
• D. It increases the production of aldosterone.

Correct answer: C

Rationale: The correct answer is C. Enalapril, an ACE inhibitor, inhibits the conversion of angiotensin I to angiotensin II, leading to increased levels of bradykinin. The accumulation of bradykinin is responsible for the persistent dry cough associated with ACE inhibitors like enalapril. Choices A, B, and D are incorrect because enalapril does not directly affect the production of angiotensin II or aldosterone. Instead, it primarily impacts the renin-angiotensin-aldosterone system by inhibiting the conversion of angiotensin I to angiotensin II, leading to bradykinin accumulation.

3. A client with a history of chronic obstructive pulmonary disease (COPD) is prescribed salmeterol. The nurse should monitor for which potential side effect?

• A. Dry mouth
• B. Tachycardia
• C. Insomnia
• D. Increased appetite

Correct answer: A

Rationale: The correct answer is dry mouth. Salmeterol, a long-acting beta agonist used in COPD, can lead to dry mouth as a common side effect. Nurses should monitor for this side effect and advise clients to report it if it becomes bothersome.

4. A client with a diagnosis of bipolar disorder is prescribed oxcarbazepine. The nurse should monitor for which potential adverse effect?

• A. Hyponatremia
• B. Agranulocytosis
• C. Liver toxicity
• D. Weight gain

Correct answer: A

Rationale: The correct answer is A, Hyponatremia. Oxcarbazepine, an anticonvulsant used in bipolar disorder, can lead to hyponatremia. This is because it can cause the body to retain water, leading to a dilution of sodium levels in the blood. Monitoring sodium levels is crucial to prevent complications such as confusion, seizures, and even coma. Choices B, C, and D are incorrect. Agranulocytosis is not typically associated with oxcarbazepine use. Liver toxicity is a potential adverse effect of some medications but not commonly seen with oxcarbazepine. While weight gain can be a side effect of certain medications used in bipolar disorder treatment, it is not a common adverse effect of oxcarbazepine.

5. A client with diabetes mellitus type 2 is prescribed dapagliflozin. The nurse should monitor for which potential adverse effect?

• A. Genital infections
• B. Hypoglycemia
• C. Hyperglycemia
• D. Nausea

Correct answer: A

Rationale: The correct answer is A: Genital infections. Dapagliflozin, a medication used in diabetes mellitus type 2, is associated with an increased risk of genital infections. Its mechanism of action involves promoting glucose excretion through the urine, creating a favorable environment for microbial growth in the genital area. Monitoring for genital infections is crucial when a client is prescribed dapagliflozin. Hypoglycemia (choice B) is not a common adverse effect of dapagliflozin since it does not directly lower blood glucose levels. Hyperglycemia (choice C) is also unlikely as dapagliflozin is intended to help lower blood glucose levels. Nausea (choice D) is a less common side effect of dapagliflozin compared to genital infections.
