Correct Answer: A

Rationale: The correct answer is A because the Nursing Interventions Classification (NIC) system is not designed to help medical students determine the cost of care. The NIC system focuses on standardizing and categorizing nursing interventions to improve communication, documentation, and patient care. Choice B is incorrect because it correctly identifies one of the benefits of using the NIC system - enhancing communication among nurses. Choice C is incorrect because it suggests a valid use of the NIC system for organizing orientation and explaining nursing interventions. Choice D is incorrect because it accurately states that the NIC system can improve documentation in the electronic health record, which is one of its purposes.

Correct Answer: A

Rationale: The correct answer is A: Avoid alcohol and caffeine. Alcohol and caffeine are diuretics that can increase urine output, leading to fluid loss and potential hypovolemia. This step is crucial in preventing further dehydration. Summary of incorrect choices: B: Increasing milk and dairy products can contribute to fluid intake but does not address the prevention of hypovolemia. C: While dried peas and beans can provide nutrients, they do not specifically address fluid intake or prevention of hypovolemia. D: Avoiding table salt or sodium-containing foods may help in reducing fluid retention but does not directly address fluid intake to prevent hypovolemia.

Correct Answer: A

Rationale: The correct answer is A: emergency. In this scenario, the patient is experiencing difficulty in urination due to benign prostate hyperplasia (BPH), a condition that can lead to serious complications like acute urinary retention. Transurethral resection of the prostate (TURP) is a surgical procedure that is used to relieve the obstruction caused by BPH. Given the urgency of the situation and the potential for acute complications, the surgery needs to be performed immediately to prevent further harm to the patient's health. Classifying this condition as an emergency ensures prompt intervention and prioritizes the patient's well-being. Summary: - B: C.urgent (not correct): While the surgery is time-sensitive, it does not require immediate intervention like in an emergency situation. - C: elective (not correct): Elective surgeries are planned in advance and are not typically performed in urgent situations like this one. - D: required (not correct): While the surgery is necessary for the patient's condition

Correct Answer: B

Rationale: The correct answer is B: The waiting area with the television turned off. This choice eliminates potential distractions, allowing the patient with a hearing deficit to focus on the interview. Noise from the television can interfere with communication. Other choices are incorrect because: A) The closed door may block out external noise, but the patient's room could still have distractions. C) Administering pain medication can affect the patient's alertness and ability to communicate effectively. D) The waiting room with occupational therapy activities can be noisy and distracting. Conducting the interview in a quiet waiting area ensures optimal communication and understanding.

Correct Answer: C

Rationale: The correct answer is C: A 6-hour glucose tolerance test. This test involves measuring blood glucose levels at specific intervals after consuming a glucose solution, providing a comprehensive assessment of glucose utilization over time. This test is particularly useful in evaluating how the body processes glucose after a meal and can help diagnose conditions such as diabetes. A: A fasting blood glucose test would not provide a comprehensive picture of glucose utilization over time since it only measures glucose levels in a fasted state. B: A test of serum glycosylated hemoglobin (HbA1c) reflects average blood glucose levels over the past 2-3 months but does not directly assess glucose utilization after a meal. D: A test for urine ketones is used to detect ketones in the urine, which can indicate diabetic ketoacidosis but does not directly measure glucose utilization.
