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. In which of the following cases is Lansoprazole not used?

A. Gastritis
B. Peptic Ulcers
C. Zollinger-Ellison syndrome
D. Thalamus hypertrophy

Correct answer: D

Rationale: Lansoprazole is a proton pump inhibitor mainly used to treat conditions related to the stomach, such as gastritis, peptic ulcers, and Zollinger-Ellison syndrome. Thalamus hypertrophy is not a condition that Lansoprazole is indicated for; it is used for gastrointestinal issues and not neurological conditions.

3. A client has a new prescription for Calcitonin-salmon for Osteoporosis. Which of the following tests should the nurse tell the client to expect before beginning this medication?

A. Skin test for allergy to the medication
B. ECG to rule out cardiac dysrhythmias
C. Mantoux test to rule out exposure to tuberculosis
D. Liver function tests to assess risk for medication toxicity

Correct answer: A

Rationale: Before starting Calcitonin-salmon, it is important to assess for any potential allergies as anaphylaxis can occur. A skin test is usually conducted to determine if the client is allergic to the medication. The nurse should also inquire about any previous allergies to fish, as Calcitonin-salmon is derived from salmon. Options B, C, and D are not necessary before initiating Calcitonin-salmon therapy. ECG is not directly related to this medication, Mantoux test is used to diagnose tuberculosis, and liver function tests are not specifically required before starting Calcitonin-salmon.

4. A client has been prescribed Atorvastatin to lower cholesterol. Which of the following instructions should the nurse include?

A. Take this medication with a full glass of water.
B. Report any muscle pain to your provider immediately.
C. Avoid drinking grapefruit juice while taking this medication.
D. Take this medication at bedtime to prevent drowsiness.

Correct answer: B

Rationale: The correct instruction for the nurse to include is to 'Report any muscle pain to your provider immediately.' Muscle pain can be a sign of rhabdomyolysis, a rare but serious side effect of statins like atorvastatin. It is crucial to monitor for potential complications, and reporting muscle pain promptly can lead to timely intervention if needed. Choices A, C, and D are incorrect because they do not address a critical side effect of atorvastatin or provide essential information for the client's safety and well-being.

5. When caring for a client prescribed Digoxin, which of the following laboratory values should the nurse monitor to assess for potential toxicity?

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

Correct answer: B

Rationale: When a client is prescribed Digoxin, monitoring potassium levels is crucial as hypokalemia can increase the risk of Digoxin toxicity. Low potassium levels can potentiate the effects of Digoxin on the heart, leading to toxicity. Therefore, regular monitoring of potassium levels helps in preventing adverse effects and ensuring the safe use of Digoxin. Sodium, magnesium, and calcium levels are not directly associated with Digoxin toxicity; hence, they are not the primary focus for monitoring in this case.
