Nursing Elites

1. A client with hypertension is prescribed atenolol. The nurse should monitor the client for which potential side effect?

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

Correct answer: A

Rationale: When a client is prescribed atenolol, a beta-blocker medication used to treat hypertension, the nurse should monitor for bradycardia as a potential side effect. Atenolol works by slowing the heart rate, and one common adverse effect is bradycardia, which is a slower than normal heart rate. Monitoring the client's heart rate is essential to detect and manage this potential side effect promptly. Choices B, C, and D are incorrect because atenolol typically does not cause tachycardia, hypotension, or hyperglycemia as primary side effects. Instead, bradycardia is a common concern due to the drug's mechanism of action in reducing heart rate.

2. A client with a diagnosis of generalized anxiety disorder is prescribed lorazepam. The client should be informed that this medication may have which potential side effect?

• A. Drowsiness
• B. Dry mouth
• C. Nausea
• D. Headache

Correct answer: A

Rationale: The correct answer is A: Drowsiness. Lorazepam, a medication commonly used to treat anxiety disorders, can lead to drowsiness as a common side effect. It is important for clients to be aware of this potential effect, and they should be advised to avoid activities like driving until they understand how the medication affects them. Dry mouth, nausea, and headache are possible side effects of other medications but are less commonly associated with lorazepam.

3. A client has metoprolol prescribed. The nurse should reinforce instructions that this medication has which potential adverse effect?

• A. Anxiety
• B. Tachycardia
• C. Sexual dysfunction
• D. Acute renal failure

Correct answer: C

Rationale: The correct answer is C: Sexual dysfunction. Metoprolol, a beta-blocker, can cause sexual dysfunction as an adverse effect. It is important for the nurse to educate the client about this potential side effect. Choice A is incorrect because metoprolol can cause depression, not anxiety. Choice B is incorrect as tachycardia is not an adverse effect of metoprolol; instead, it can lead to bradycardia. Choice D is incorrect because acute renal failure is not typically associated with the use of beta-blockers.

4. When should a glucagon emergency kit be used for a client with Type 1 diabetes?

• A. During episodes of hypoglycemia
• B. At the onset of signs of diabetic ketoacidosis
• C. Before meals to prevent hyperglycemia
• D. When signs of severe hypoglycemia occur

Correct answer: D

Rationale: A glucagon emergency kit is used when signs of severe hypoglycemia occur in a client with Type 1 diabetes. Glucagon helps raise blood glucose levels in cases of severe hypoglycemia when the individual is unable to take oral glucose. It is crucial to administer glucagon promptly to prevent serious complications associated with low blood sugar levels. Choices A, B, and C are incorrect because a glucagon emergency kit is specifically indicated for severe hypoglycemia, not for general episodes of hypoglycemia, diabetic ketoacidosis, or prevention of hyperglycemia.

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.
