Nursing Elites

1. A client has a new prescription for hydrochlorothiazide. The client should monitor for which of the following adverse effects?

• A. Hyponatremia
• B. Ototoxicity
• C. Hypoglycemia
• D. Hyperkalemia

Correct answer: A

Rationale: Hyponatremia is a potential adverse effect of hydrochlorothiazide due to its diuretic action. Hydrochlorothiazide is a thiazide diuretic that can cause sodium and water loss, potentially leading to hyponatremia. Monitoring for symptoms such as weakness, confusion, and muscle cramps can help detect hyponatremia early. Ototoxicity (choice B) is not a common adverse effect of hydrochlorothiazide. Hypoglycemia (choice C) is not typically associated with hydrochlorothiazide use. Hyperkalemia (choice D) is more commonly associated with potassium-sparing diuretics rather than thiazide diuretics like hydrochlorothiazide.

2. What is the therapeutic use of Phenytoin?

• A. Replacement in hypothyroidism to restore normal hormonal balance
• B. Diminished accumulation of acid in the gastric lumen with lessened gastroesophageal reflux
• C. Diminished seizure activity, termination of ventricular arrhythmias
• D. Prevention of thrombus formation, prevention of extension of existing thrombi

Correct answer: C

Rationale: Phenytoin is primarily used to diminish seizure activity and is effective in terminating ventricular arrhythmias. It works by stabilizing neuronal membranes, reducing repetitive neuronal firing, and limiting the spread of seizure activity in the brain. While phenytoin does not have a direct role in preventing thrombus formation or extending existing thrombi, it is crucial in managing seizures and certain arrhythmias.

3. A client is taking Furosemide for heart failure. Which of the following laboratory tests should the nurse monitor to assess for an adverse effect of this medication?

• A. Serum potassium.
• B. Serum calcium.
• C. Serum sodium.
• D. Serum magnesium.

Correct answer: A

Rationale: Furosemide, a loop diuretic commonly used in heart failure, can cause hypokalemia (low potassium levels) as a side effect. Monitoring serum potassium levels is crucial to detect and prevent complications associated with low potassium levels, such as cardiac arrhythmias. Therefore, the nurse should prioritize assessing the client's serum potassium levels regularly while on Furosemide. Serum calcium, sodium, and magnesium levels are not typically affected by Furosemide and are not the primary focus of monitoring for adverse effects of this medication.

4. A client has a new prescription for Hydroxychloroquine to treat Lupus Erythematosus. Which of the following adverse effects should the nurse include in the teaching?

• A. Nausea
• B. Hair loss
• C. Eye damage
• D. Drowsiness

Correct answer: C

Rationale: The correct answer is 'C: Eye damage.' Hydroxychloroquine can cause severe adverse effects on the eyes, such as retinopathy, which can lead to permanent visual impairment. It is essential for clients to be aware of this potential adverse effect and report any changes in vision promptly. Choices A, B, and D are incorrect because although nausea, hair loss, and drowsiness can occur with Hydroxychloroquine, they are not as severe or critical as the risk of eye damage.

5. What is the antidote for Warfarin?

• A. Vitamin D
• B. Vitamin C
• C. Vitamin K
• D. Vitamin B6

Correct answer: C

Rationale: Vitamin K is the antidote for Warfarin toxicity as it helps reverse the anticoagulant effects of Warfarin. Warfarin works by inhibiting vitamin K-dependent clotting factors, and administering vitamin K can replenish these factors, thereby counteracting the anticoagulant effects of Warfarin. Vitamin D, Vitamin C, and Vitamin B6 do not have the specific mechanism to counteract the anticoagulant effects of Warfarin, making them incorrect choices.
