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 with chronic obstructive pulmonary disease (COPD) is prescribed tiotropium. The nurse should instruct the client to report which potential side effect?

• A. Dry mouth
• B. Blurred vision
• C. Nausea
• D. Tachycardia

Correct answer: A

Rationale: The correct answer is A: Dry mouth. Tiotropium, a commonly prescribed medication for COPD, can cause dry mouth as a side effect. While it may not be severe, clients should report it if it becomes bothersome. Dry mouth is a common side effect of tiotropium due to its anticholinergic properties. Blurred vision, nausea, and tachycardia are not typically associated with tiotropium use in the context of COPD.

3. When a client with hepatic encephalopathy is receiving lactulose, which parameter is essential to monitor for a response to the drug?

• A. Serum hepatic enzymes
• B. Fingerstick glucose
• C. Stool color and character
• D. Serum electrolytes and ammonia

Correct answer: D

Rationale: In hepatic encephalopathy, the goal of lactulose therapy is to reduce blood ammonia levels by promoting its excretion in the stool. Therefore, monitoring serum electrolytes and ammonia levels is crucial to assess the effectiveness of lactulose in lowering ammonia levels and improving the client's condition. Options A, B, and C are incorrect because serum hepatic enzymes, fingerstick glucose, and stool color/character are not directly related to monitoring the response to lactulose therapy in hepatic encephalopathy.

4. A client with a history of atrial fibrillation is prescribed digoxin. The nurse should monitor for which potential side effect?

• A. Bradycardia
• B. Tachycardia
• C. Headache
• D. Hyperglycemia

Correct answer: A

Rationale: The correct answer is A: Bradycardia. Digoxin can lead to bradycardia due to its effect on slowing down the heart rate, which can be dangerous in a client with atrial fibrillation. Monitoring the client's heart rate is essential to detect and manage this potential side effect. Choices B, C, and D are incorrect because digoxin is not known to cause tachycardia, headache, or hyperglycemia as common side effects.

5. The practical nurse is assigned a client on digoxin therapy. Which finding is likely to predispose this client to developing digoxin toxicity?

• A. Hyponatremia
• B. Hypernatremia
• C. Hyperkalemia
• D. Hypokalemia

Correct answer: D

Rationale: Hypokalemia predisposes a client on digoxin to digoxin toxicity. Symptoms of digoxin toxicity include abdominal pain, anorexia, nausea, vomiting, visual disturbances, bradycardia, and atrioventricular (AV) dissociation. Therefore, assessment of serum potassium levels and prompt correction of hypokalemia are crucial interventions for clients taking digoxin.
