1. A client has a new prescription for Lovastatin. Which of the following instructions should be included?
- A. Take this medication on an empty stomach.
- B. Take this medication in the morning.
- C. Take this medication at bedtime.
- D. Increase your intake of potassium-rich foods.
Correct answer: C
Rationale: Lovastatin should be taken at bedtime because cholesterol production in the liver is highest at night, making the medication more effective in reducing cholesterol levels. By taking it at bedtime, the medication aligns with the body's natural rhythm of cholesterol synthesis, optimizing its therapeutic effects.
2. A client has a new prescription for Furosemide. Which of the following dietary instructions should the nurse provide?
- A. Increase your intake of bananas and oranges.
- B. Limit your intake of calcium-rich foods.
- C. Avoid drinking milk.
- D. Increase your intake of green, leafy vegetables.
Correct answer: A
Rationale: The correct answer is A: 'Increase your intake of bananas and oranges.' Furosemide, a loop diuretic, can cause potassium loss leading to hypokalemia. To prevent this, clients should increase their intake of potassium-rich foods, such as bananas and oranges, to replenish potassium levels. Choices B, C, and D are incorrect because limiting calcium-rich foods or avoiding milk is not necessary with Furosemide, and increasing intake of green, leafy vegetables does not specifically address the potential potassium loss associated with this medication.
3. A healthcare provider is reviewing the health care record of a client who is asking about conjugated equine estrogens. The provider should inform the client this medication is contraindicated in which of the following conditions?
- A. Atrophic vaginitis
- B. Dysfunctional uterine bleeding
- C. Osteoporosis
- D. Thrombophlebitis
Correct answer: D
Rationale: Conjugated equine estrogens are contraindicated in clients with a history of thrombophlebitis due to the increased risk of thrombotic events associated with estrogen use. Thrombophlebitis is characterized by inflammation of a vein with the formation of a clot, and estrogen can further exacerbate this condition, leading to serious complications. Choices A, B, and C are not contraindications for conjugated equine estrogens. Atrophic vaginitis and osteoporosis are conditions where estrogen therapy may actually be indicated. Dysfunctional uterine bleeding is another condition where estrogen therapy can be used to help regulate menstrual bleeding.
4. 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.
5. A client with angina is seeking a prescription for sildenafil to manage erectile dysfunction. Which of the following medications is contraindicated with Sildenafil?
- A. Aspirin
- B. Isosorbide
- C. Clopidogrel
- D. Atorvastatin
Correct answer: B
Rationale: Isosorbide, an organic nitrate used for angina, is contraindicated with sildenafil due to the risk of fatal hypotension. Concurrent use of these medications can lead to severe hypotension. Patients are advised to avoid taking nitrate medications for 24 hours after using isosorbide to prevent this dangerous interaction.
