1. A healthcare professional is monitoring a client who is receiving spironolactone. Which of the following findings should the professional report to the provider?
- A. Serum Sodium 144 mEq/L
- B. Urine output 120 mL in 4 hours
- C. Serum Potassium 5.2 mEq/L
- D. Blood Pressure 140/90 mm Hg
Correct answer: C
Rationale: A serum potassium level of 5.2 mEq/L indicates hyperkalemia, which is a potentially dangerous condition. Spironolactone, a potassium-sparing diuretic, can cause potassium retention, leading to hyperkalemia. This electrolyte imbalance can result in serious consequences such as cardiac dysrhythmias. The healthcare professional should promptly report this finding to the provider, withhold the medication, and take appropriate actions to prevent complications. Monitoring and managing potassium levels are crucial in clients receiving spironolactone. The other options do not directly relate to the potential adverse effects of spironolactone and are within normal limits, making them less urgent to report.
2. A healthcare professional is preparing to administer heparin 15,000 units subcutaneously every 12 hours. The available heparin injection is 20,000 units/mL. How many milliliters should the healthcare professional administer per dose?
- A. 0.8 mL
- B. 0.75 mL
- C. 0.5 mL
- D. 1 mL
Correct answer: A
Rationale: To calculate the volume to administer, use the formula: Desired dose / Concentration = Volume to administer. In this case, (15,000 units / 20,000 units/mL) = 0.75 mL. Since the volume needs to be rounded up to the nearest tenth, the correct answer is 0.8 mL. Choice B (0.75 mL) is incorrect because it does not account for rounding up the volume. Choices C (0.5 mL) and D (1 mL) are incorrect as they do not reflect the precise calculation based on the given concentration and desired dose.
3. A healthcare provider is providing discharge instructions to a client who is prescribed Prednisone. Which of the following dietary instructions should the healthcare provider include?
- A. Increase your intake of potassium-rich foods.
- B. Increase your intake of dairy products.
- C. Avoid foods high in vitamin K.
- D. Decrease your intake of protein.
Correct answer: A
Rationale: The correct answer is to increase the intake of potassium-rich foods (Choice A). Prednisone can cause potassium depletion, so clients should increase their intake of foods such as bananas, oranges, and spinach. Potassium-rich foods help maintain electrolyte balance and prevent complications associated with low potassium levels, such as muscle weakness and irregular heartbeats. Choices B, C, and D are incorrect because increasing dairy products (Choice B) or avoiding foods high in vitamin K (Choice C) are not specifically related to Prednisone therapy. Decreasing protein intake (Choice D) is also not necessary in this case.
4. Hydrochlorothiazide is classified as a
- A. Anti-inflammatory
- B. Antiarrhythmic
- C. Diuretic
- D. Antifungal
Correct answer: C
Rationale: Hydrochlorothiazide is classified as a diuretic. Diuretics are medications that help the body get rid of excess salt and water by increasing urine production, reducing fluid retention, and lowering blood pressure. Option A, Anti-inflammatory, is incorrect because hydrochlorothiazide does not primarily reduce inflammation. Option B, Antiarrhythmic, is incorrect because hydrochlorothiazide is not used to correct heart rhythm irregularities. Option D, Antifungal, is incorrect because hydrochlorothiazide is not used to treat fungal infections.
5. Why has an ACE inhibitor been prescribed following an MI?
- A. “This medication will lower your potassium level.â€
- B. “ACE inhibitors have been found to reduce mortality following MI.â€
- C. “ACE inhibitors are always prescribed with a beta blocker and calcium channel blocker following an MI.â€
- D. “This medication will treat your hypotension.â€
Correct answer: B
Rationale: Following a myocardial infarction (MI), ACE inhibitors are commonly prescribed due to their proven benefit in reducing mortality and improving outcomes post-MI. These medications help by decreasing the workload of the heart, preventing remodeling of the heart chambers, and improving survival rates. While ACE inhibitors may have effects on potassium levels, the primary reason for their prescription post-MI is their mortality-reducing properties.
