1. What is the classification of furosemide?

A. Loop diuretic
B. Anticoagulant
C. Iron supplement
D. Anticonvulsant

Correct answer: A

Rationale: Furosemide is classified as a loop diuretic, not an anticoagulant, iron supplement, or anticonvulsant. Loop diuretics, like furosemide, act in the loop of Henle in the kidney to inhibit sodium and chloride reabsorption, leading to increased urine output. This mechanism makes them effective in treating conditions such as edema and hypertension. Therefore, the correct classification for furosemide is a loop diuretic (Choice A).

2. When caring for a client prescribed Lithium, which laboratory value should the nurse monitor to assess for potential toxicity?

A. Serum sodium
B. Serum lithium
C. Serum potassium
D. Serum calcium

Correct answer: B

Rationale: The nurse should monitor the client's serum lithium levels to ensure they are within the therapeutic range and to assess for potential toxicity. Monitoring serum lithium levels is crucial because lithium has a narrow therapeutic range, and levels outside this range can lead to toxicity, which can be life-threatening. Therefore, regular monitoring is essential to prevent adverse effects and ensure the medication's effectiveness.

3. A client has a new prescription for Prednisone. Which of the following laboratory values should the nurse monitor?

A. Serum potassium
B. Serum calcium
C. Serum sodium
D. Serum glucose

Correct answer: D

Rationale: The correct answer is D, Serum glucose. Prednisone is a corticosteroid that can lead to hyperglycemia. Monitoring serum glucose levels is essential to assess for elevated blood sugar levels. Choices A, B, and C are incorrect as Prednisone does not directly affect potassium, calcium, or sodium levels.

4. Which of the following conditions is not treated with epinephrine?

A. Renal disease
B. Asthma
C. Hypotension
D. Glaucoma

Correct answer: A

Rationale: Epinephrine is not used to treat renal disease. Epinephrine is commonly used to treat conditions like asthma, hypotension, and glaucoma, but it is not an appropriate treatment for renal disease. Renal disease requires specific management strategies that do not involve the use of epinephrine.

5. A client has a new prescription for Efavirenz, an NNRTI. Which of the following instructions should the nurse include?

A. Take this medication at bedtime to prevent drowsiness.
B. Take this medication with a glass of milk.
C. Take this medication with a glass of juice.
D. Take this medication at the same time every day.

Correct answer: A

Rationale: The correct instruction is to take Efavirenz at bedtime to prevent drowsiness and manage central nervous system side effects like dizziness and vivid dreams. While it is important to take the medication at the same time daily for consistent blood levels, the emphasis should be on bedtime to minimize the impact of these side effects. Choices B and C suggesting taking the medication with milk or juice are incorrect and not relevant to optimizing Efavirenz therapy.
