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 taking Digoxin, low levels of what can cause toxicity?

A. Potassium
B. Calcium
C. Sodium
D. Magnesium

Correct answer: A

Rationale: Low potassium levels can lead to Digoxin toxicity. Digoxin competes with potassium for binding sites on the sodium-potassium pump. When potassium levels are low, there is an increased risk of Digoxin binding and toxicity. Choice B (Calcium) is incorrect because low calcium levels are not directly linked to Digoxin toxicity. Choice C (Sodium) is incorrect as low sodium levels do not cause Digoxin toxicity. Choice D (Magnesium) is incorrect as low magnesium levels do not contribute to Digoxin toxicity.

3. A client is prescribed Ranitidine. Which of the following laboratory results should be monitored by the nurse?

A. Complete blood count (CBC).
B. Serum creatinine.
C. Serum potassium.
D. Serum glucose.

Correct answer: A

Rationale: Ranitidine can potentially lead to blood dyscrasias, necessitating the monitoring of the client's CBC. Checking the CBC can help detect any abnormalities in blood cell counts and assess the client's overall hematologic status during Ranitidine therapy.

4. When caring for a client with a wound infection, which action should the nurse perform first in the plan of care?

A. Administer antibiotic medication.
B. Obtain a wound specimen for culture.
C. Review WBC laboratory findings.
D. Apply a dressing to the wound.

Correct answer: B

Rationale: The priority action when caring for a client with a wound infection is to obtain a wound specimen for culture before initiating antibiotic therapy. This step is crucial to identify the specific microorganism causing the infection, allowing for targeted antibiotic treatment. Reviewing WBC laboratory findings and applying a wound dressing are important steps, but obtaining a wound specimen for culture takes precedence as it guides appropriate antibiotic therapy by identifying the causative organism.

5. A client is starting therapy with Metformin. Which of the following instructions should the nurse include?

A. Take this medication with your first bite of food.
B. Take this medication on an empty stomach.
C. Take this medication before bedtime.
D. Take this medication every other day.

Correct answer: A

Rationale: Metformin should be taken with meals to reduce gastrointestinal side effects and ensure better absorption. Instructing the client to take the medication with the first bite of food helps in achieving optimal effectiveness and minimizes the risk of side effects like nausea or upset stomach. Choice B is incorrect because taking Metformin on an empty stomach can lead to increased gastrointestinal side effects. Choice C is incorrect as there is no specific timing requirement for taking Metformin before bedtime. Choice D is incorrect as Metformin is usually taken daily, not every other day.
