1. Which of the following diuretics inhibits sodium reabsorption in the kidneys while sparing K+ and hydrogen ions?

• A. Spironolactone
• B. Furosemide
• C. Hydrochlorothiazide
• D. Bumetanide

Correct answer: A

Rationale: Spironolactone is the correct answer as it is classified as a potassium-sparing diuretic. It works by inhibiting sodium reabsorption in the kidneys while promoting the retention of potassium and hydrogen ions. This mechanism of action helps in reducing fluid retention without causing excessive loss of potassium, which is a common side effect of other diuretics. Furosemide (choice B), Hydrochlorothiazide (choice C), and Bumetanide (choice D) are not correct as they are not potassium-sparing diuretics. Furosemide and Bumetanide are loop diuretics that inhibit sodium, potassium, and chloride reabsorption in the loop of Henle. Hydrochlorothiazide is a thiazide diuretic that inhibits sodium and chloride reabsorption in the distal convoluted tubule, leading to potassium loss.

2. A healthcare professional is caring for a client who has a new prescription for Lisinopril. Which of the following laboratory values should the professional monitor?

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

Correct answer: A

Rationale: Lisinopril is an ACE inhibitor that can cause hyperkalemia by reducing the excretion of potassium in the kidneys. Monitoring serum potassium levels is essential to prevent complications such as cardiac arrhythmias. Therefore, the healthcare professional should closely monitor the client's serum potassium levels when they are on Lisinopril. Choices B, C, and D are incorrect because Lisinopril primarily affects potassium levels due to its mechanism of action as an ACE inhibitor. Serum sodium, calcium, and magnesium levels are not typically affected by Lisinopril in the same way as potassium.

3. While reviewing a client's medical history, a healthcare professional notes a prescription for Digoxin. Which of the following findings is a manifestation of Digoxin toxicity?

• A. Elevated blood pressure
• B. Bradycardia
• C. Yellow-tinged vision
• D. Ringing in the ears

Correct answer: C

Rationale: Yellow-tinged vision is a visual disturbance associated with Digoxin toxicity, often accompanied by other symptoms like nausea, vomiting, and confusion. Bradycardia is a common therapeutic effect of Digoxin, while elevated blood pressure and ringing in the ears are not typically associated with Digoxin toxicity. Therefore, the correct answer is yellow-tinged vision as a manifestation of Digoxin toxicity.

4. Which of the following is not a side effect of the vasodilator Nifedipine?

• A. Nausea
• B. Flushed appearance
• C. Vertigo
• D. Sexual dysfunction

Correct answer: D

Rationale: Sexual dysfunction is not a common side effect of vasodilators such as Nifedipine. Nausea, flushed appearance, and vertigo are more commonly reported side effects associated with this medication. It's essential for healthcare providers to be aware of the potential side effects to monitor and manage them effectively in patients prescribed with Nifedipine.

5. Which medication is used as a bronchodilator?

• A. Warfarin
• B. Lovastatin
• C. Albuterol
• D. Valproate

Correct answer: C

Rationale: Albuterol is the correct answer. It is a medication commonly used as a bronchodilator to treat conditions such as asthma. Albuterol works by relaxing the muscles in the airways, allowing better airflow and making breathing easier for individuals with respiratory conditions. Warfarin (Choice A) is an anticoagulant used to prevent blood clots, Lovastatin (Choice B) is a medication used to lower cholesterol levels, and Valproate (Choice D) is used to treat seizures and bipolar disorder. These medications are not bronchodilators and are used for different medical conditions.
