1. What is the most concerning electrolyte imbalance for a patient receiving digoxin?

Correct answer: B

Rationale: The correct answer is Hypokalemia. Hypokalemia is the most concerning electrolyte imbalance for a patient receiving digoxin because it can increase the risk of digoxin toxicity. Low potassium levels can potentiate the effects of digoxin on the heart, leading to serious cardiac arrhythmias. Hyperkalemia (Choice A) is not typically associated with digoxin use. Hyponatremia (Choice C) and Hypercalcemia (Choice D) are not directly related to digoxin therapy and do not pose the same risk of toxicity.

2. A patient is 1 day postoperative following a total knee arthroplasty. Which of the following actions should the nurse take?

Correct answer: D

Rationale: The correct action for a client 1 day postoperative following a total knee arthroplasty is to apply ice packs to the affected knee. Ice packs help reduce swelling and pain in such clients. Administering aspirin is contraindicated due to the risk of bleeding postoperatively. Keeping the affected leg in a dependent position can impair circulation and increase the risk of complications. Flexing the affected knee for extended periods can strain the surgical site and hinder the healing process.

3. A client with a new diagnosis of peptic ulcer disease is receiving teaching from a nurse. Which of the following statements by the client indicates an understanding of the teaching?

Correct answer: B

Rationale: The correct answer is B. Clients with peptic ulcer disease should avoid spicy foods as they can exacerbate symptoms and delay healing. Ibuprofen can worsen peptic ulcers by irritating the stomach lining, so it should be avoided. While limiting dairy products may be beneficial for some individuals with lactose intolerance, it is not a specific recommendation for peptic ulcer disease. Taking antacids before meals can help neutralize stomach acid; however, the timing may vary depending on the type of antacid, so there is no universal rule of taking antacids 30 minutes before meals. Choice A is incorrect because the client should avoid taking ibuprofen due to its potential to worsen peptic ulcers. Choice C is incorrect as there is no direct correlation between dairy product intake and peptic ulcer disease. Choice D is incorrect because the timing of antacid administration can vary and should be guided by specific recommendations.

4. A nurse is providing discharge teaching to a client who has a new prescription for metformin. Which of the following instructions should the nurse include?

Correct answer: D

Rationale: The correct answer is D because taking metformin with food helps reduce gastrointestinal discomfort, a common side effect of the medication. Choice A is incorrect as metformin is usually taken with meals to minimize side effects. Choice B is incorrect because metformin does not typically cause urine discoloration. Choice C is incorrect as metformin is associated with weight loss or weight neutrality rather than weight gain.

5. A client receiving intermittent enteral feedings is being cared for by a nurse. Which action should the nurse take to reduce the risk of aspiration?

Correct answer: C

Rationale: The correct action to reduce the risk of aspiration during enteral feedings is to elevate the head of the bed to 45 degrees. This position helps prevent the reflux of feeding into the lungs. Administering the feeding over 60 minutes (Choice A) does not directly reduce the risk of aspiration. Positioning the client in a supine position (Choice B) increases the risk of aspiration as it promotes reflux. Flushing the feeding tube with water (Choice D) is important for tube patency but does not directly reduce the risk of aspiration.
