Correct Answer: D

Rationale: The correct answer is to cleanse the wound from the center outwards. This technique helps prevent infection and promotes healing by ensuring that any contaminants are moved away from the center of the wound. Administering a protein supplement (choice A) or increasing protein intake in the client's diet (choice B) may be beneficial for overall healing but are not the most appropriate interventions specifically for wound care. Increasing IV fluid intake (choice C) is important for hydration but is not the most appropriate intervention for managing a pressure ulcer.

Correct Answer: B

Rationale: The correct manifestation to expect when collecting data from a client with PTSD is hypervigilance. Hypervigilance refers to increased alertness, which is a common symptom of PTSD. This heightened state of awareness is characterized by an exaggerated startle response, being easily startled, and constantly scanning the environment for potential threats. Amnesia (choice A) is not typically a primary manifestation of PTSD; it is more commonly associated with dissociative disorders. Hallucinations (choice C) involve perceiving things that are not present and are not typically a hallmark symptom of PTSD. Severe agitation (choice D) may occur in individuals with PTSD, but hypervigilance is a more specific and common manifestation associated with this disorder.

Correct Answer: A

Rationale: The correct signs and symptoms of Cushing's syndrome are weight gain and a moon face. Corticosteroids are used to manage Cushing's syndrome by reducing the overproduction of cortisol. Choice B is incorrect because hirsutism and thin extremities are not typical signs of Cushing's syndrome. Choice C is incorrect as purple striae and muscle weakness are more characteristic of the syndrome. Choice D is also incorrect as hypertension and bruising are not primary signs of Cushing's syndrome.

Correct Answer: A

Rationale: Diabetic ketoacidosis and retinopathy are indeed common complications of untreated Type 1 diabetes. Diabetic ketoacidosis occurs when the body starts breaking down fat for fuel, leading to a dangerous buildup of ketones in the blood. Retinopathy refers to damage to the blood vessels of the retina due to high blood sugar levels over time. The other choices, hypoglycemia and neuropathy (choice B), hypotension and kidney failure (choice C), and infection and fluid overload (choice D) are not typically the primary complications associated with untreated Type 1 diabetes.

Correct Answer: C

Rationale: The best strategy to ensure the safety of a client with dementia who frequently wanders is to place a bed exit alarm system. This system alerts staff when the client attempts to leave the bed, reducing the risk of falls. Choice A, using restraints, is not the best approach as it can lead to complications and is not recommended unless absolutely necessary. Choice B, encouraging the client to walk in a monitored area, may not be effective in preventing wandering as the client may still wander away. Choice D, asking family members to stay with the client at all times, may not be feasible or practical, especially for round-the-clock supervision.
