Rationale: Fidelity is a principle in nursing ethics that pertains to being faithful or loyal to commitments and promises made to patients. When Nurse Pat promised to come back to assist in the patient's ambulation after carrying out the physician's order, she is demonstrating fidelity by fulfilling her commitment to the patient's care. This principle helps build trust between the nurse and the patient, ensuring continuity and quality of care.

Correct Answer: D

Rationale: The primary goal of enhancing communication skills for a nurse is to establish rapport with patients, which can lead to better outcomes, increased patient satisfaction, and improved quality of care. Generating a threat between the nurse and the patient is counterproductive to building rapport and does not align with the intention of enhancing communication skills in healthcare settings.

Correct Answer: C

Rationale: In cases of persistent fetal malpresentation, such as a transverse lie position, a cesarean section is often the safest and most effective intervention to address the abnormal labor presentation. Delivering a baby in a transverse lie position vaginally is associated with high risks, including fetal complications such as umbilical cord prolapse and head entrapment. Therefore, to ensure the safety of both the mother and the baby, a cesarean section is usually the most appropriate and timely intervention to address this situation. It is crucial to prioritize the immediate preparation and facilitation of a cesarean section in cases of persistent fetal malpresentation to prevent potential complications and ensure the best outcome for the mother and the baby.

Correct Answer: A

Rationale: The diagnostic examination for osteoporosis typically involves measuring bone density. This is usually done through a dual-energy x-ray absorptiometry (DEXA) scan, which is considered the gold standard for assessing bone density. Osteoporosis is characterized by decreased bone mass and deterioration of bone tissue, leading to increased bone fragility and risk of fractures. Measuring bone density helps in diagnosing osteoporosis by identifying areas of low bone density, assessing the risk of fractures, and monitoring the effectiveness of treatment. Weight, blood volume, and height are not directly used as primary indicators for diagnosing osteoporosis.
