1. A healthcare professional is preparing to administer vancomycin 1 g by intermittent IV bolus. Available is vancomycin 1 g in 100 mL of dextrose 5% in water (D5W) to infuse over 45 min. The drop factor of the manual IV tubing is 10 gtt/mL. How many gtt/min should the healthcare professional adjust the manual IV infusion to deliver?

• A. 22 gtt/min
• B. 24 gtt/min
• C. 20 gtt/min
• D. 18 gtt/min

Correct answer: A

Rationale: To calculate the flow rate, use the formula: (Volume in mL x Drop factor) / Time in minutes = Flow rate in gtt/min. In this case, (100 mL x 10 gtt/mL) / 45 min = 22 gtt/min. Thus, the healthcare professional should adjust the manual IV infusion to deliver 22 gtt/min. Choice B, 24 gtt/min, is incorrect because it miscalculates the flow rate. Choices C and D, 20 gtt/min and 18 gtt/min, are also incorrect as they do not accurately calculate the flow rate based on the given information.

2. A client is taking Furosemide for heart failure. Which of the following findings is a priority to report to the provider?

• A. Weight loss of 1 kg in 24 hours
• B. Blood pressure of 104/60 mm Hg
• C. Potassium level of 3.5 mEq/L
• D. Urine output of 200 mL in 8 hours

Correct answer: D

Rationale: A urine output of 200 mL in 8 hours indicates decreased kidney function, potentially due to Furosemide therapy. This finding can suggest inadequate renal perfusion and impaired drug clearance, necessitating immediate reporting to prevent further complications like electrolyte imbalances and worsening heart failure. Choice A: Weight loss may be expected in heart failure patients due to fluid retention, but it is not an immediate concern. Choice B: A blood pressure of 104/60 mm Hg is slightly low but not a priority compared to the indication of kidney dysfunction. Choice C: A potassium level of 3.5 mEq/L is within the normal range, so it does not require immediate reporting.

3. 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.

4. Which of the following is a potassium-sparing diuretic?

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

Correct answer: B

Rationale: Spironolactone is classified as a potassium-sparing diuretic. It works by antagonizing the aldosterone receptor, leading to potassium retention and sodium excretion. This mechanism makes it a suitable choice for conditions where potassium retention is desired, such as in patients with heart failure or liver cirrhosis. Choices A, C, and D are not potassium-sparing diuretics. Furosemide, hydrochlorothiazide, and bumetanide are loop diuretics and thiazide diuretics, respectively, which promote the excretion of potassium.

5. A client is taking lisinopril. Which of the following outcomes indicates a therapeutic effect of the medication?

• A. Decreased blood pressure
• B. Increase in HDL cholesterol
• C. Prevention of bipolar manic episodes
• D. Improved sexual function

Correct answer: A

Rationale: The therapeutic effect of lisinopril, an ACE inhibitor, is indicated by a decrease in blood pressure. Lisinopril works by relaxing blood vessels, leading to a reduction in blood pressure. Monitoring and achieving a decrease in blood pressure is a key outcome when managing hypertension with lisinopril. Choices B, C, and D are incorrect because lisinopril is not intended to increase HDL cholesterol, prevent bipolar manic episodes, or improve sexual function. Therefore, the correct outcome indicating the therapeutic effect of lisinopril is a decrease in blood pressure.
