Which nursing intervention supports the principles on which the cross-links theory of aging is based?

Correct Answer: D

Rationale: The correct answer is D because selecting foods high in vitamins A, C, and E supports the principles of the cross-links theory of aging, which focuses on the accumulation of damage from oxidative stress. Vitamins A, C, and E are antioxidants that help combat oxidative stress and reduce the formation of cross-links in tissues. This intervention can potentially slow down the aging process by reducing cellular damage. Choice A is incorrect because applying an elastin-sustaining moisturizer does not directly address the oxidative stress aspect of the cross-links theory of aging. Choice B is incorrect as assessing family history for genetic diseases does not specifically target the mechanisms involved in the cross-links theory of aging. Choice C is incorrect because questioning about exposure to environmental toxins may be important for overall health but is not directly related to the principles of the cross-links theory of aging.

Correct Answer: A

Rationale: The correct answer is A: Implement suicide precautions. This is the highest priority because the patient has a plan for suicide, which poses an immediate risk to their safety. Implementing suicide precautions involves ensuring the patient's environment is safe, removing any potential means of self-harm, and closely monitoring the patient to prevent any suicide attempts. Choice B is incorrect because offering high-calorie snacks and fluids frequently addresses the physical aspect of weight loss but does not address the immediate safety concern of suicide. Choice C is incorrect because assisting the patient to identify personal strengths is important for building self-esteem but is not the highest priority when the patient is at risk for suicide. Choice D is incorrect because observing the patient for therapeutic effects of antidepressant medication is important but not as urgent as ensuring the patient's safety in the case of suicidal ideation.

Correct Answer: D

Rationale: The correct answer is D: Suicide precautions. The patient's statement indicates they are experiencing severe depression and suicidal ideation. Suicide precautions should be the highest priority to ensure the patient's safety. This includes removing any potential means of self-harm, constant monitoring, and close supervision. Self-esteem-building activities (A) may be helpful in the long term but are not the immediate priority. Anxiety self-control measures (B) are important but addressing suicidal ideation takes precedence. Sleep enhancement activities (C) are also important but not the highest priority when dealing with suicidal thoughts.

Correct Answer: B

Rationale: The correct answer is B because it seeks clarification and prompts the patient to specify who they are referring to when they say "everybody." This response shows active listening and encourages deeper communication. Choice A offers sympathy but doesn't address the issue directly. Choice C dismisses the significance of "frobitzing." Choice D asks for the reason behind "frobitzing" without seeking clarification on the people involved.

Correct Answer: D

Rationale: The correct answer is D because focusing on the feelings suggested by the delusion can help the patient process and manage their emotions underlying the delusion. By addressing the emotions, the nurse can help the patient gain insight into the delusion and reduce its intensity. Confronting the delusion (A) may lead to resistance and reinforcement. Refuting the delusion with logic (B) may further alienate the patient. Exploring reasons for the delusion (C) may not directly address the emotional component.
