1. A client has a prescription for Trimethoprim-Sulfamethoxazole. Which of the following instructions should the nurse include?

A. Take the medication with food.
B. Increase fluid intake.
C. Expect reddish-orange urine.
D. Avoid high-protein foods.

Correct answer: B

Rationale: The correct instruction for a client prescribed Trimethoprim-Sulfamethoxazole is to increase fluid intake. This helps prevent crystalluria and kidney stones, which are potential adverse effects of this medication. Adequate hydration is essential to reduce the risk of these complications.

2. What is the therapeutic use of Albuterol?

A. Bronchodilation
B. Anti-coagulant
C. Anti-arrhythmic
D. Proton-pump inhibitor

Correct answer: A

Rationale: The correct answer is A: Bronchodilation. Albuterol is primarily used for bronchodilation, where it relaxes the muscles in the airways to make breathing easier. This medication is commonly prescribed for conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other respiratory conditions where bronchodilation is beneficial. Choices B, C, and D are incorrect because Albuterol is not used as an anti-coagulant, anti-arrhythmic, or proton-pump inhibitor.

3. A client with active tuberculosis asks why he must take four different medications. Which of the following responses should the nurse make?

A. Taking four medications decreases the risk of a severe allergic reaction.
B. Taking four medications reduces the chance that the bacteria will become resistant.
C. Taking four medications reduces the risk of adverse reactions.
D. Taking four medications decreases the chance of having a positive tuberculin skin test.

Correct answer: B

Rationale: When treating tuberculosis, using a combination of multiple medications is crucial to reduce the risk of bacterial resistance. The use of four medications helps to target the bacteria from different angles, making it harder for them to develop resistance to the treatment. This approach is essential to ensure the effectiveness of the treatment regimen and to prevent the spread of drug-resistant strains of tuberculosis. Choices A, C, and D are incorrect because the primary reason for using multiple medications in tuberculosis treatment is to prevent the development of bacterial resistance, not to decrease the risk of allergic reactions, adverse reactions, or affecting the tuberculin skin test results.

4. A client has a new prescription for Valsartan. Which of the following adverse effects should the nurse monitor?

A. Hyperkalemia
B. Hypoglycemia
C. Bradycardia
D. Hypercalcemia

Correct answer: A

Rationale: Corrected Rationale: Valsartan is an angiotensin II receptor blocker (ARB) that can cause hyperkalemia by affecting the renin-angiotensin-aldosterone system. The nurse should closely monitor the client's potassium levels due to the risk of hyperkalemia, which can lead to serious cardiac complications. Choice B, hypoglycemia, is not a common adverse effect of Valsartan. Choice C, bradycardia, is not directly associated with Valsartan use. Choice D, hypercalcemia, is not a typical adverse effect of Valsartan.

5. What is the action of Nitroglycerin?

A. Dilates the Bronchi
B. Reduces Blood Glucose
C. Reduces Nausea
D. Dilates Coronary Arteries

Correct answer: D

Rationale: Nitroglycerin acts by dilating the coronary arteries, leading to increased blood flow and oxygen supply to the heart. This helps in relieving angina symptoms by reducing the heart's workload and improving blood supply to the myocardium. Choices A, B, and C are incorrect because Nitroglycerin's primary action is not related to dilating bronchi, reducing blood glucose, or reducing nausea.
