Correct Answer: C

Rationale: The correct answer is C because providing emotional support and offering counseling or therapy sessions address the root cause of the patient's depression in a holistic manner. This intervention allows the patient to express their emotions, process their feelings, and receive guidance on coping strategies. Encouraging social activities (A) may not directly address the underlying emotional issues. Referring to a psychiatrist for medication (B) should be considered if counseling alone is insufficient. Exploring spiritual beliefs (D) is important but may not be the most immediate priority for addressing depression in this context.

Correct Answer: A

Rationale: The correct answer is A: Scabies. This presentation is classic for scabies infestation caused by the Sarcoptes scabiei mite. The intensely pruritic linear burrows are pathognomonic. Close contact with an individual with scabies increases the likelihood of transmission. The other choices, B: Pediculosis, C: Tinea corporis, and D: Contact dermatitis, do not typically present with linear burrows on the hands and wrists. Pediculosis presents with lice infestation, Tinea corporis with circular lesions, and contact dermatitis with erythema and edema.

Correct Answer: C

Rationale: The correct answer is C: Cells die. In Alzheimer's disease, there is a progressive degeneration of brain cells, leading to cell death. This results in a loss of important brain functions such as memory, cognition, and eventually, bodily functions. The atrophy of the brain stem (choice A) is not a characteristic feature of Alzheimer's. Fluid buildup (choice B) is not a primary mechanism of the disease. Tissue swelling (choice D) is not typically associated with the progression of Alzheimer's; rather, there is a gradual loss of brain tissue due to cell death.

Correct Answer: D

Rationale: The correct answer is D: Assess the severity of the reaction. This should be the first action taken because it helps determine the urgency of the situation and guides subsequent steps. Assessing the severity allows for appropriate intervention - from calling emergency services if the reaction is severe, to administering medication if necessary. A: Administering an epinephrine auto-injector should only be done if the severity of the reaction warrants it, as it is a potent medication that can have serious side effects if used inappropriately. B: Positioning the person comfortably is important, but assessing the severity of the reaction takes precedence to ensure prompt and appropriate care. C: Monitoring vital signs is important, but assessing the severity of the reaction is crucial in determining the immediate course of action.

Correct Answer: B

Rationale: The correct initial step before starting TPN is to evaluate the patient's tolerance to glucose. This is crucial to ensure the patient can metabolize the glucose effectively and avoid complications such as hyperglycemia. Assessing affordability (A) is important but not the immediate concern. Identifying allergies (C) should be done but is not the first step. Assessing the patient's understanding (D) is important but not as critical as evaluating glucose tolerance before starting TPN.
