Correct Answer: D

Rationale: The correct answer is D: Decreased deep tendon reflexes. In myasthenia gravis, muscle weakness is a common manifestation, leading to decreased deep tendon reflexes. Bradycardia (choice A) is not typically associated with myasthenia gravis. Increased muscle strength (choice B) is unlikely as muscle weakness is a hallmark of this condition. Diarrhea (choice C) is not a typical finding in myasthenia gravis.

Correct Answer: C

Rationale: The correct action for the nurse to take is to keep the collection device below the client's chest. This positioning ensures proper drainage of fluid from the chest, preventing backflow of fluids. Clamping the chest tube when assisting the client out of bed is incorrect as it can lead to fluid accumulation and potential complications. Emptying the drainage system every 8 hours is necessary but not the priority over maintaining proper positioning. Stripping the chest tube every 4 hours is an outdated practice and can cause damage to the tissue and should be avoided.

Correct Answer: C

Rationale: The correct answer is C: Bananas. Bananas are rich in potassium and should be included in the diet of clients taking furosemide, a potassium-wasting diuretic. Grapes, apples, and rice are not as high in potassium as bananas and would not be as effective in replenishing potassium levels in clients taking furosemide.

Correct Answer: B

Rationale: The correct answer is B. Clients taking metoprolol should regularly check their pulse and should not take the medication if their pulse is too low. Option A is incorrect because metoprolol should not be taken with a glass of milk. Option C is incorrect because stopping medication abruptly can be harmful. Option D is incorrect because antacids should not be taken with metoprolol as they can decrease its absorption.

Correct Answer: B

Rationale: When setting up a sterile field for a dressing change, the nurse should open the outermost flap of the sterile kit away from the body. This action helps maintain the sterility of the field by minimizing the risk of contamination. Option A is incorrect because the cap from the solution should be placed sterile side down to prevent contamination. Option C is incorrect because the sterile dressing should be placed at least 1.25 cm away from the edge of the sterile field to maintain its sterility. Option D is incorrect because the sterile field should be set up above waist level to prevent potential contamination from reaching the field.
