Correct Answer: C

Rationale: The correct answer is C: Repeating, milk, milk, milk, milk until given a drink. This behavior is a characteristic of children with autism, known as echolalia. Echolalia is the repetition of words or phrases spoken by others, often used by individuals with autism to communicate or self-soothe. This behavior is a common feature of autism spectrum disorder and is indicative of language difficulties and communication challenges. Choices A, B, and D are incorrect because they do not specifically relate to behaviors typically observed in children with autism. Referring to an imaginary friend (A) is not exclusive to autism, asking to telephone friends on weekends (B) is a social behavior that can be seen in children without autism, and insisting on a dim light in the bedroom (D) is a preference that does not directly relate to the core characteristics of autism.

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.

Correct Answer: A

Rationale: The correct answer is A because in bereavement, symptoms of grief and sadness tend to come and go, known as remitting and exacerbating, as the individual processes the loss over time. This is a normal part of the grieving process. On the other hand, in depression, symptoms are persistent and may not improve without intervention. Guilt feelings being overwhelming (B) is common in both bereavement and depression. Suicide thoughts being common (C) can occur in severe depression but are not a distinguishing factor between bereavement and depression. Psychomotor retardation being obvious (D) is a symptom more commonly associated with severe depression rather than bereavement.

Correct Answer: C

Rationale: Rationale: 1. Educating the patient and family is crucial as it helps alleviate anxiety and ensures informed consent. 2. Monitoring vital signs (A) should be done before, during, and after the procedure, not necessarily in a specific order. 3. Medication administration (B) should be based on physician's orders but is not the initial step. 4. Checking a signed consent (D) is important but typically done before proceeding with any procedure, not necessarily in a specific order.

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.
