Nursing Elites

1. A patient with hypertension is taking an ACE inhibitor to lower blood pressure. What should the nurse advise the patient to avoid in their diet?

• A. Vinegar
• B. Apples
• C. Salt substitutes
• D. Tomatoes

Correct answer: C

Rationale: Patients taking ACE inhibitors should avoid salt substitutes as they often contain potassium, which can lead to hyperkalemia. Hyperkalemia is an elevated level of potassium in the blood that can be dangerous, especially for patients on ACE inhibitors. Vinegar, apples, and tomatoes do not pose a risk for patients taking ACE inhibitors. Therefore, the nurse should advise the patient to avoid salt substitutes to prevent potential complications.

2. A client prescribed Warfarin is receiving discharge instructions from a nurse. Which of the following herbal supplements should the nurse instruct the client to avoid?

• A. St. John's wort
• B. Echinacea
• C. Garlic
• D. Ginseng

Correct answer: A

Rationale: St. John's wort can reduce the effectiveness of Warfarin by interacting with its metabolism pathways, potentially leading to decreased anticoagulant effects. Therefore, clients on Warfarin therapy should avoid St. John's wort. While echinacea, garlic, and ginseng are also herbal supplements that can interact with Warfarin, St. John's wort is particularly known for its significant impact on Warfarin metabolism. Echinacea may increase the risk of bleeding when taken with Warfarin, garlic may potentiate the anticoagulant effects of Warfarin, and ginseng may also increase the risk of bleeding. However, St. John's wort is the most crucial to avoid due to its significant impact on Warfarin metabolism.

3. A child is prescribed Amoxicillin 20 mg/kg/day PO to be administered every 12 hr. The child weighs 44 lb. The available medication is amoxicillin suspension 250 mg/5 mL. How many mL should be given per dose?

• A. 4 mL
• B. 5 mL
• C. 6 mL
• D. 3 mL

Correct answer: A

Rationale: To calculate the dosage per administration: Convert the weight to kg (44 lb / 2.2 lb/kg = 20 kg). Then, (20 mg/kg/day x 20 kg) / 2 (for every 12 hr dosing) = 200 mg per dose. (200 mg / 250 mg) x 5 mL = 4 mL per dose. Therefore, the nurse should administer 4 mL of amoxicillin suspension per dose. Choice B, 5 mL, is incorrect because the calculation shows that 4 mL is the correct dose. Choices C and D are also incorrect as they are not in line with the calculated dosage based on the weight of the child and the concentration of the medication.

4. A healthcare provider is reviewing the health history of a client who is starting therapy with tamoxifen. The healthcare provider should recognize that tamoxifen is contraindicated in which of the following clients?

• A. A client with a history of deep-vein thrombosis
• B. A client with a history of migraine headaches
• C. A client with a history of hypertension
• D. A client with a history of anemia

Correct answer: A

Rationale: Tamoxifen is contraindicated in clients with a history of thromboembolic events, such as deep-vein thrombosis, due to the increased risk of blood clots forming and leading to serious complications like pulmonary embolism. Clients with a history of deep-vein thrombosis are at a higher risk of recurrent thromboembolic events when taking tamoxifen, making it unsafe for such individuals. Choices B, C, and D are not contraindications for tamoxifen therapy, as migraine headaches, hypertension, and anemia do not directly interact with tamoxifen's mechanism of action or pose significant risks when used together.

5. A client has a prescription for furosemide. Which of the following instructions should the nurse include?

• A. Take furosemide in the morning.
• B. Eat a diet high in potassium.
• C. Avoid foods high in magnesium.
• D. Limit fluid intake to 1 liter per day.

Correct answer: B

Rationale: The correct instruction for a client taking furosemide is to eat a diet high in potassium. Furosemide is a loop diuretic that can lead to potassium loss, potentially causing hypokalemia. Consuming foods rich in potassium can help maintain normal potassium levels in the body and counteract the potential side effect of furosemide. Choices A, C, and D are incorrect because taking furosemide in the morning does not specifically relate to its effectiveness or side effects, avoiding foods high in magnesium is not a primary concern when taking furosemide, and limiting fluid intake to 1 liter per day is not a general recommendation for individuals taking furosemide.
