Correct Answer: D

Rationale: The correct answer is D because clients should press the button on the PCA pump when they feel pain to receive controlled doses of medication. Option A is incorrect as the client should be the one to self-administer the medication through the PCA pump. Option B is incorrect as the primary purpose of the PCA pump is to manage pain, not to keep the client comfortable. Option C is incorrect because the client should not adjust the dosage themselves; instead, they should communicate any pain concerns to the healthcare provider.

Correct Answer: D

Rationale: In the management of sepsis, prompt intervention is crucial. Administering IV antibiotics is essential to target the underlying infection. Monitoring blood pressure helps assess the patient's hemodynamic status. Administering fluids is vital to maintain adequate perfusion. Therefore, all the options are integral components of the initial management of sepsis, making 'All of the above' the correct answer. Choosing any single intervention over the others may delay optimal care and compromise patient outcomes.

Correct Answer: D

Rationale: The most relevant suggestion for minimizing stress in individuals with Alzheimer's disease is to maintain consistency in the environment, routine, and caregivers. This approach helps create a sense of familiarity and security for the individual, reducing stress and anxiety. Choice A is incorrect as it suggests allowing the client to go to bed multiple times during the day, which may disrupt their routine and lead to confusion. Choice B is incorrect as continuously testing cognitive functioning can be overwhelming and stressful for the individual. Choice C is also incorrect as providing reality orientation in cases of severe memory loss can cause frustration and confusion, ultimately increasing stress levels.

Correct Answer: B

Rationale: The correct instruction the nurse should include is to 'Stop exercising if pain occurs.' In peripheral arterial disease (PAD), it is crucial to avoid exercising to the point of pain as this may worsen the condition and lead to complications. Exercising to the point of pain can result in inadequate blood flow to the extremities, causing further damage. By stopping exercise if pain occurs, the client can prevent exacerbating their condition. Choices A, C, and D are incorrect because exercising to the point of pain, limiting exercise to once per week, and avoiding walking altogether are not recommended strategies for managing PAD and could potentially harm the client.

Correct Answer: C

Rationale: The correct answer is to hold your breath for 5-10 seconds after inhaling when using a metered-dose inhaler (MDI) for asthma management. This action ensures proper medication absorption in the lungs. Inhaling rapidly (choice A) may cause the medication to impact the mouth/throat rather than the lungs. Exhaling completely before inhalation (choice B) does not optimize medication delivery. Inhaling slowly (choice D) may not allow the medication to reach the lungs effectively.
