Correct Answer: C

Rationale: The correct answer is C. Encouraging the client to use an incentive spirometer every hour is crucial to prevent respiratory complications postoperatively. Incentive spirometry helps in lung expansion and prevents atelectasis, which is common after abdominal surgery. Choice A, encouraging ambulation, is important for preventing complications but does not directly address respiratory issues. Choice B, deep breathing and coughing every hour, is also beneficial but not as effective in preventing atelectasis as using an incentive spirometer. Choice D, instructing the client to avoid coughing, is incorrect as coughing helps clear secretions and prevent respiratory complications.

Correct Answer: A

Rationale: The correct answer is to place the client in a negative pressure room. This action is necessary to prevent the spread of tuberculosis, as it is transmitted via airborne particles. Placing the client in droplet isolation (choice C) is not sufficient for tuberculosis, as it requires airborne precautions. Wearing a surgical mask (choice B) when entering the client's room may not provide adequate protection against airborne transmission. Placing a surgical mask on the client when transporting them (choice D) does not address the need for environmental controls to contain infectious particles.

Correct Answer: B

Rationale: The correct answer is B: 'Sleep with the head of your bed elevated.' Elevating the head of the bed helps reduce acid reflux by keeping the head higher than the stomach, preventing stomach acid from flowing back into the esophagus. Choices A, C, and D are incorrect. Avoiding eating small, frequent meals, lying down after eating, and drinking fluids with meals can exacerbate GERD symptoms by increasing stomach acid production and promoting acid reflux.

Correct Answer: A

Rationale: The best nursing intervention for a patient experiencing fluid overload is to administer diuretics. Diuretics help the body to remove excess fluid by increasing urine output. This intervention is crucial in managing fluid overload. Administering IV fluids (Choice B) would worsen the condition by adding more fluids to the already overloaded system. Providing oral fluids (Choice C) is not appropriate as it would further contribute to the fluid overload. Chest physiotherapy (Choice D) is not indicated in the treatment of fluid overload and would not address the underlying issue of excess fluid accumulation.
