Correct Answer: A

Rationale: The correct answer is A: Evaluation. Evaluation involves assessing the appropriateness and effectiveness of care provided to the patient. It helps determine if the care aligns with the patient's current physiological and psychological status. Choice B, Planning, refers to developing a plan of care based on assessment data. Choice C, Implementation, involves carrying out the planned interventions. Choice D, Assessment, is the initial step that involves collecting data about the patient's condition.

Correct Answer: D

Rationale: Older men and women are at higher risk for drug-nutrient interactions due to factors such as polypharmacy and physiological changes. Polypharmacy, common in older adults, increases the likelihood of interactions between drugs and nutrients. Physiological changes that occur with aging can affect how drugs and nutrients are absorbed, distributed, metabolized, and excreted in the body. Infants, people with diabetes, and women of childbearing age are not typically considered high-risk groups for drug-nutrient interactions compared to older adults.

Correct Answer: B

Rationale: Assessing the client's bilateral pedal pulses is essential in this situation as it helps in evaluating the peripheral perfusion and circulation in the lower extremities. This assessment is crucial to detect any signs of decreased blood flow or complications, such as arterial occlusion or thrombosis. Ambulating the client may be important in the postoperative period, but assessing pedal pulses takes priority to ensure adequate perfusion. Maintaining continuous IV heparin drip is not typically indicated immediately post-operatively for an abdominal aortic aneurysm repair, as the risk of bleeding complications may outweigh the benefits. Providing a clear liquid diet is not a priority nursing intervention at this stage, as the focus should be on vascular assessment and postoperative monitoring.

Correct Answer: A

Rationale: The correct answer is A. A head circumference of 40 cm is abnormally large for a newborn and could indicate conditions like hydrocephalus or other abnormalities, making it a crucial finding to report. Choices B, C, and D are within normal parameters for a newborn and do not pose immediate concerns. Chest circumference of 32 cm is a normal finding. Acrocyanosis and edema of the scalp are common in newborns due to physiological adaptations. A heart rate of 160 bpm and respirations of 40/min may be within the normal range for a newborn.

Correct Answer: B

Rationale: The Physician Assistant is the first individual in the combat health support chain to make medically substantiated decisions based on their military occupational specialty-specific medical training. While physicians are highly trained medical professionals, in the context of combat health support, the Physician Assistant is typically the frontline provider who directly applies their specific military medical training to make decisions. Combat medics and combat lifesavers may provide critical care in the field, but they do not have the same level of training and scope of practice as a Physician Assistant in this context, making them less likely to be the first to make medically substantiated decisions.
