Correct Answer: D

Rationale: The correct answer is D because crossing arms and legs can indicate defensiveness or discomfort, which may suggest the parent is uneasy discussing their son's treatment. This nonverbal cue could signal a need for empathy and sensitivity in communication. Choice A is incorrect as it overlooks the significance of body language. Choice B assumes comfort without considering the context. Choice C assumes tiredness without considering other possibilities. Understanding body language cues can help in building rapport and addressing concerns effectively.

Correct Answer: C

Rationale: The correct answer is C: subjective. Subjective data refers to information provided by the patient based on their feelings, perceptions, and experiences. In this case, the patient's report of feeling nervous, nauseated, and hot is subjective because it reflects their personal sensations and cannot be measured or observed directly by the nurse. Objective data (choice A) is measurable and observable, such as vital signs or physical examination findings. Reflective (choice B) and introspective (choice D) do not accurately describe the type of data provided by the patient in this scenario. The patient's symptoms are subjective because they are based on the patient's own feelings and experiences, making choice C the most appropriate answer.

Correct Answer: A

Rationale: The correct answer is A: Encouraging early ambulation to prevent deep vein thrombosis. Early ambulation helps prevent blood clot formation in the legs, reducing the risk of deep vein thrombosis post-surgery. It also promotes circulation and aids in preventing complications like pneumonia. Administering pain medication (B) is important, but preventing complications should take priority. Providing wound care (C) is essential but not the top priority. Encouraging a high-protein diet (D) is beneficial for healing, but immediate post-operative mobility is crucial for preventing complications.

Correct Answer: C

Rationale: The correct answer is C: sodium and chloride. In the extracellular fluid, sodium and chloride are the major electrolytes due to their roles in maintaining fluid balance, nerve function, and muscle contraction. Potassium and phosphate (choice B) are primarily found in intracellular fluid, while potassium and chloride (choice A) are not the major electrolytes in extracellular fluid. Similarly, sodium and phosphate (choice D) are not major extracellular electrolytes. Thus, choice C is the correct answer based on the significant presence and functions of sodium and chloride in the extracellular fluid.

Correct Answer: D

Rationale: The correct answer is D. Hypertension can lead to various complications affecting the heart, kidneys, and brain. Monitoring for heart failure is crucial due to the increased workload on the heart. Chronic kidney disease is a common complication of hypertension, as the kidneys are sensitive to changes in blood pressure. Stroke is another significant risk due to the potential damage to blood vessels in the brain. Therefore, monitoring for all these complications is essential in managing a patient with hypertension. Other choices are incorrect as they do not encompass all possible complications of hypertension.
