Correct Answer: C

Rationale: The correct answer is C, 'Epistaxis.' Epistaxis (nosebleed) is a common adverse effect of prolonged nasogastric tube insertion due to irritation of the nasal mucosa. Dry mucous membranes (choice A) may indicate dehydration but are not a direct adverse effect of nasogastric tube insertion. Polyuria (choice B) is excessive urination and is not typically associated with nasogastric tube insertion. Diarrhea (choice D) is also not a common adverse effect of having a nasogastric tube in place.

Correct Answer: C

Rationale: The correct instruction for a client taking furosemide is to increase their intake of potassium-rich foods. Furosemide is a loop diuretic that can lead to potassium loss, so increasing potassium-rich foods helps prevent hypokalemia. Choice A, avoiding prolonged exposure to sunlight, is not directly related to furosemide use. Choice B, taking the medication with a meal, is not a specific requirement for furosemide administration. Choice D, limiting fluid intake to 1 liter per day, is not the correct advice as furosemide is a diuretic that often requires increased fluid intake to prevent dehydration.

Correct Answer: A

Rationale: Furosemide is the correct answer. It is a common diuretic used in patients with heart failure to reduce fluid overload. Metoprolol (Choice B) is a beta-blocker often prescribed to manage heart failure symptoms by improving heart function. Digoxin (Choice C) is used in heart failure patients to help the heart beat stronger and with a more regular rhythm. Aspirin (Choice D) is not typically prescribed for heart failure but may be used in patients with heart disease for its antiplatelet effects.

Correct Answer: C

Rationale: The correct answer is C. Sleeping on the affected side could increase the risk of dislocation following a hip arthroplasty. It is essential for the client to avoid sleeping on the surgical side to prevent complications. Choices A, B, and D are correct statements that promote proper postoperative care and reduce the risk of complications. Avoiding crossing legs when sitting, using a raised toilet seat for proper positioning, and performing leg exercises regularly help in the recovery process and prevent complications.

Correct Answer: D

Rationale: When a nurse notes early decelerations in electronic fetal monitoring, it indicates head compression, which is generally considered benign and not associated with fetal hypoxia, abruptio placentae, or post maturity. Early decelerations mirror the uterine contractions and are a normal response to fetal head compression during labor.
