Correct Answer: C

Rationale: Changing the entire pouching system weekly is essential for maintaining skin integrity and preventing infection. Option A is incorrect as applying a skin barrier should be done during the pouch change, not separately. Option B is incorrect as ileostomy pouches should be emptied when they are one-third to one-half full to prevent leakage. Option D is incorrect because cleansing the peristomal skin with alcohol can be too harsh and may cause skin irritation.

Correct Answer: C

Rationale: In a mass casualty situation, a client with hypovolemic shock should be the priority as they require immediate intervention to restore fluid volume and prevent further deterioration. Hypovolemic shock can lead to organ failure and death if not addressed promptly. While clients with other severe conditions like massive head trauma, full-thickness burns, or an open fracture also need urgent care, hypovolemic shock directly threatens the client's life due to inadequate circulating blood volume. Therefore, stabilizing the client with indications of hypovolemic shock takes precedence over others in this scenario.

Correct Answer: A

Rationale: Administering IV fluids is the best intervention for a patient with dehydration because it is the fastest and most effective way to rehydrate the body. IV fluids can quickly restore fluid volume and electrolyte balance in severe cases of dehydration. Providing oral fluids or encouraging fluid intake may not be sufficient for patients with moderate to severe dehydration, as they may have impaired gastrointestinal absorption. While electrolytes are essential for rehydration, administering them alone without fluid replacement may not address the primary issue of fluid loss in dehydration.

Correct Answer: A

Rationale: The best intervention for a patient experiencing severe hypoglycemia is to administer IV dextrose. This intervention is necessary to rapidly raise blood sugar levels in critical situations. Administering oral glucose may not be effective in severe cases as the patient may be unable to consume it. Monitoring blood sugar levels and rechecking blood sugar in 15 minutes are important steps but not the initial best intervention for severe hypoglycemia.

Correct Answer: C

Rationale: The correct answer is C because bending at the hips can dislocate the hip joint in clients who have had a total hip arthroplasty. This movement should be avoided to prevent complications post-surgery. Choices A, B, and D are all correct statements for a client who has had a total hip arthroplasty. Avoiding prolonged sitting, crossing legs, and using a raised toilet seat are all appropriate measures to ensure proper healing and prevent complications.
