Correct Answer: B

Rationale: The correct answer is B: Loss of interest in usual activities. Clients with PTSD often exhibit symptoms such as numbing, which can manifest as a loss of interest in activities they once enjoyed. Choice A, dependence on family and friends, is more indicative of seeking support rather than a direct symptom of PTSD. Choice C, ritualistic behavior, is more commonly associated with conditions like obsessive-compulsive disorder. Choice D, passive-aggressive behavior, is not a typical finding in clients with PTSD.

Correct Answer: A

Rationale: Administering anticoagulants is the most crucial nursing action for a patient experiencing a deep vein thrombosis (DVT). Anticoagulants help prevent further clot formation and reduce the risk of complications such as pulmonary embolism. Encouraging ambulation, applying compression stockings, and monitoring oxygen saturation are important interventions in managing DVT, but administering anticoagulants takes priority as it directly targets the clotting process and prevents clot progression.

Correct Answer: B

Rationale: Placing a pillow between the patient's legs is the correct action to prevent dislocation of the hip following arthroplasty. This technique helps maintain proper alignment and stability of the hip joint. Keeping the patient in a side-lying position may not provide the necessary support to prevent hip dislocation. Instructing the patient to avoid sitting for long periods is important for preventing complications like deep vein thrombosis but does not directly prevent hip dislocation. Elevating the head of the bed to 90 degrees is not relevant to preventing hip dislocation in a postoperative hip arthroplasty patient.

Correct Answer: A

Rationale: Administering oxygen is the best intervention for a patient experiencing respiratory distress because it helps improve oxygenation and alleviate respiratory distress. Oxygen therapy is a critical and priority intervention in such cases as it aims to increase oxygen levels in the blood. Administering bronchodilators may be beneficial for specific respiratory conditions like asthma or COPD, but oxygen should be the initial priority. Administering IV fluids and providing humidified air, while important in certain situations, are not the primary interventions for respiratory distress.

Correct Answer: D

Rationale: The correct answer is D. Warmth and redness in the calf are indicative of a possible deep vein thrombosis (DVT), a serious complication post-surgery that requires immediate attention. Reporting this finding promptly to the provider is crucial for timely intervention. Choices A, B, and C are within normal limits for a postoperative client and do not indicate a potentially life-threatening condition like DVT.
