Nursing Elites

1. Which drug classes are NOT typically used to treat angina?

• A. Calcium channel blockers
• B. Organic nitrates
• C. Alpha blockers
• D. Beta blockers

Correct answer: C

Rationale: Angina is primarily treated with calcium channel blockers, organic nitrates, and beta blockers. Alpha blockers are not commonly used in the treatment of angina. Calcium channel blockers help dilate blood vessels, decreasing the workload on the heart. Organic nitrates relax and widen blood vessels, improving blood flow and reducing the heart's workload. Beta blockers reduce the heart rate and blood pressure, decreasing the heart's demand for oxygen. Alpha blockers are more commonly used to treat conditions like hypertension and benign prostatic hyperplasia.

2. A healthcare professional is preparing to administer Diltiazem IV to a client who has atrial fibrillation. Which of the following findings should the healthcare professional report immediately?

• A. Bradycardia.
• B. Hypertension.
• C. Shortness of breath.
• D. Tachycardia.

Correct answer: A

Rationale: The correct answer is bradycardia. Diltiazem, a calcium channel blocker, can lead to bradycardia as a side effect. Bradycardia should be reported immediately because it can result in serious cardiac complications, especially in a client with atrial fibrillation. Hypertension, shortness of breath, and tachycardia are not typically associated with Diltiazem administration and would not be immediate concerns in this scenario.

3. A healthcare provider is preparing to administer dextrose 5% in water (D5W) 750 mL IV to infuse over 6 hr. How many mL/hr should the IV pump be set to deliver?

• A. 125 mL/hr
• B. 100 mL/hr
• C. 150 mL/hr
• D. 200 mL/hr

Correct answer: A

Rationale: To calculate the flow rate, divide the total volume by the total time: (750 mL / 6 hr) = 125 mL/hr. Therefore, the IV pump should be set to deliver 125 mL/hr to infuse dextrose 5% in water (D5W) over 6 hours. Choice B, 100 mL/hr, is incorrect as it does not match the correct calculation. Choice C, 150 mL/hr, is incorrect as it is higher than the calculated flow rate. Choice D, 200 mL/hr, is incorrect as it is also higher than the calculated flow rate.

4. A healthcare professional in a provider's clinic is caring for a client who reports erectile dysfunction and requests a prescription for sildenafil. Which of the following medications currently prescribed for the client is a contraindication to taking sildenafil?

• A. Isosorbide
• B. Phenytoin
• C. Metronidazole
• D. Prednisone

Correct answer: A

Rationale: Sildenafil is contraindicated with nitrates like isosorbide due to the risk of severe hypotension. Isosorbide is a nitrate that can potentiate the hypotensive effects of sildenafil, leading to a dangerous drop in blood pressure. Therefore, it is essential to avoid concurrent use of isosorbide and sildenafil to prevent adverse effects. Phenytoin, metronidazole, and prednisone do not have significant interactions with sildenafil and are not contraindicated when used together.

5. A client is receiving spironolactone. Which of the following findings should the nurse report to the provider?

• A. Serum Sodium 144 mEq/L
• B. Urine output 120 mL in 4 hrs
• C. Serum Potassium 5.2 mEq/L
• D. Blood Pressure 140/90 mmHg

Correct answer: C

Rationale: A serum potassium level of 5.2 mEq/L indicates hyperkalemia. Spironolactone is a potassium-sparing diuretic that can lead to potassium retention. The nurse should notify the provider and withhold the medication to prevent further elevation of potassium levels, which can result in serious cardiac complications. The other findings (Serum Sodium 144 mEq/L, Urine output 120 mL in 4 hrs, and Blood Pressure 140/90 mmHg) are within normal ranges and not directly related to spironolactone therapy.
