Correct Answer: A

Rationale: The correct answer is A: Early menopause. A client who goes into early menopause, from natural or surgical causes, is at greater risk for developing osteoporosis due to the rapid drop in estrogen levels. Choice B, history of falls, is not a direct risk factor for osteoporosis but can lead to fractures in individuals with osteoporosis. Choice C, African American race, is actually associated with a lower risk of osteoporosis compared to Caucasian or Asian descent. Choice D, obesity, is generally considered a protective factor against osteoporosis due to the increased mechanical loading on bones.

Correct Answer: B

Rationale: The correct answer is B because shortness of breath is an indication of transplant rejection, along with other manifestations like fatigue, edema, bradycardia, and hypotension. Choice A is incorrect because immunosuppressant medications are usually taken for life to prevent rejection. Choice C is incorrect as the surgical site may take longer to heal fully. Choice D is incorrect as the initiation of exercise post-heart transplant should be gradual and individualized based on the client's condition.

Correct Answer: A

Rationale: Choice A is the correct answer. This statement demonstrates effective coping as the client is showing acceptance of their disability and planning for the future with realistic goals. Choice B reflects denial of the permanent disability by stating that they will only be in a wheelchair temporarily. Choice C shows distress and a lack of acceptance by questioning why the injury happened and why they are not improving. Choice D indicates feelings of hopelessness and being a burden, which are not signs of effective coping.

Correct Answer: B

Rationale: A positive Kernig's sign is identified when a client is unable to extend their leg completely without pain after hip flexion. This finding indicates meningeal irritation. Choices A, C, and D do not describe Kernig's sign. Choice A describes a normal plantar reflex, choice C refers to coordination issues, and choice D describes neck pain and stiffness, which are not specific to Kernig's sign.

Correct Answer: B

Rationale: When using the ABC approach to client care, the nurse should identify that the priority intervention is administering oxygen. In this scenario, the client's oxygen saturation is only 91%, which is below the normal range of 95% and above. Oxygen is essential for adequate tissue perfusion and oxygenation of vital organs. Administering oxygen takes precedence over other interventions to ensure the client's physiological needs are met first. Choice A can be addressed after ensuring adequate oxygenation. Choice C is important for preventing postoperative complications but is not as urgent as addressing oxygen saturation. Choice D is a common postoperative intervention, but in this case, ensuring adequate oxygenation is the priority over IV fluid administration.
