Correct Answer: A

Rationale: The correct answer is A because monitoring for orthostatic hypotension is crucial when clients are receiving antipsychotic drugs since it is a common side effect. Orthostatic hypotension can lead to symptoms like dizziness and falls, making it essential to monitor blood pressure regularly. Choices B, C, and D are incorrect because most antipsychotic drugs do not typically cause elevated blood pressure, monitoring blood pressure is not directly related to the amount of sodium in the diet, and blood pressure monitoring is not primarily used to determine the need for anti-parkinsonian drugs in clients receiving antipsychotic medications.

Correct Answer: A

Rationale: The correct answer is A. Using sugar-free gum can help alleviate the metallic taste often experienced during chemotherapy treatments. Choices B, C, and D are incorrect. Drinking fluids at mealtime may worsen early satiety, foods higher in fat can exacerbate nausea, and raw fruits and vegetables may be harder for the body to digest and may pose a risk of infection for individuals with compromised immune systems.

Correct Answer: A

Rationale: To prevent unnecessary hypoxia during suctioning of a tracheostomy, the nurse must apply suction for no more than 10 seconds. Prolonged suctioning can lead to hypoxia by removing too much oxygen from the patient. Maintaining a sterile technique (choice B) is important to prevent infection but does not directly relate to preventing hypoxia. Lubricating the catheter tip (choice C) helps with the insertion process but does not specifically address hypoxia prevention. Withdrawing the catheter in a circular motion (choice D) is not a standard practice during tracheostomy suctioning and does not contribute to preventing hypoxia.

Correct Answer: A

Rationale: The correct answer is A: A 79-year-old malnourished client on bed rest. This client is at the highest risk for developing decubitus ulcers due to poor nutrition and immobility. Malnutrition can impair tissue healing and increase susceptibility to skin breakdown, while prolonged bed rest can lead to pressure ulcers. Choice B is incorrect because obesity can cushion pressure points and reduce the risk of pressure ulcers. Choice C is incorrect as incontinence predisposes to moisture-associated skin damage rather than pressure ulcers. Choice D is incorrect as an ambulatory client is less likely to develop pressure ulcers compared to bedridden clients.

Correct Answer: A

Rationale: Assessing the client's usual pattern of activity is crucial as it helps the nurse understand the client's current level of physical activity, any limitations, and areas needing improvement. This information is essential to create a safe and effective exercise plan tailored to the client's specific needs. Choice B, assisting the client in developing a healthy eating plan, is important but not the first step when the client's immediate goal is to start an exercise program. Encouraging the client to join a support group may be beneficial for motivation and emotional support but is not the priority at this stage. Providing a list of signs and symptoms to report to the provider is important for client education but is not the initial step when the client expresses a desire to begin an exercise program.
