Correct Answer: C

Rationale: The correct answer is C: Bone marrow. Blood cells are primarily formed in the bone marrow through a process called hematopoiesis. The bone marrow contains stem cells that differentiate into various types of blood cells, including red blood cells, white blood cells, and platelets. Arterioles are small blood vessels that carry blood away from the heart, not involved in blood cell formation. Lymphoid tissue plays a role in immune function but not in blood cell production. Muscle tissue is primarily responsible for movement and does not have a role in blood cell formation. Therefore, the bone marrow is the correct answer as it is the main site of blood cell production in the body.

Correct Answer: C

Rationale: The correct answer is C: Acute pain. The patient's right femur fracture would likely cause significant pain. Treating the pain is a priority to ensure the patient's comfort and promote healing. Posttrauma syndrome (A) is more applicable for patients experiencing emotional distress following a traumatic event. Constipation (B) may be a concern due to immobility but is not as immediate as managing pain. Anxiety (D) may be present but addressing the acute pain would likely alleviate some anxiety as well.

Correct Answer: D

Rationale: The correct answer is D: leukocytosis. Carbamazepine can cause bone marrow suppression, leading to leukocytosis. Monitoring for elevated white blood cell count is essential to detect this potential complication early. A: Adult respiratory distress syndrome is not a common complication of carbamazepine. B: Elevated levels of phenytoin is not a direct complication of carbamazepine use. C: Diplopia is a common side effect of carbamazepine, not a potential complication like leukocytosis.

Correct Answer: B

Rationale: The correct answer is B: Discuss the negative feelings with the client. This is the most appropriate action as it allows the nurse to address and manage their own biases and attitudes towards the client in a professional and constructive manner. By acknowledging and discussing these feelings with the client, the nurse can work towards providing non-judgmental care and fostering a therapeutic relationship. A: Sharing these feelings with the client is not appropriate as it can harm the nurse-client relationship and potentially lead to discrimination. C: Developing a written interview form is not addressing the immediate issue of the nurse's negative attitude towards the client. D: Avoiding eye contact with the client is unprofessional and does not address the underlying issue of the nurse's negative feelings.

Correct Answer: C

Rationale: The most pertinent nursing diagnosis for this patient is acute pain (Choice C). This is because the patient's right femur fracture would likely cause significant pain and discomfort, which is a priority to address for optimal recovery and comfort. Managing pain effectively is crucial in promoting healing and preventing complications. Posttrauma syndrome (Choice A) is not as immediate a concern in this scenario. While constipation (Choice B) and anxiety (Choice D) are important considerations, addressing acute pain takes precedence in the initial plan of care to ensure the patient's comfort and well-being.
