Correct Answer: B

Rationale: The correct action is to administer antibiotics as ordered first because pelvic inflammatory disease is caused by an infection, usually from sexually transmitted organisms. Administering antibiotics promptly is crucial to prevent further complications and treat the underlying infection. This helps to alleviate the source of the pain. Rating pain severity, administering analgesics, and patient education are important but should come after addressing the infection to prevent worsening of the condition.

Correct Answer: D

Rationale: The correct answer is D: Increased calcium level. Parathyroid hormone functions to increase blood calcium levels. When calcium levels are low, the parathyroid gland releases PTH to stimulate the release of calcium from bones and increase calcium absorption from the intestines and kidneys. This helps to maintain normal calcium levels in the blood. Choices A, B, and C are incorrect because decreased phosphate level, functioning thyroid gland, and adequate vitamin D level are not direct requirements for the action of parathyroid hormone.

Correct Answer: B

Rationale: The correct answer is B: Teach him to perform Kegel's exercises 10 to 20 times per hour. This is the appropriate action because Kegel's exercises help strengthen the pelvic floor muscles, which can improve urinary control and reduce dribbling post-TURP. Restricting fluid intake (A) is not necessary and may lead to dehydration. Reinserting the Foley catheter (C) is not recommended as it can increase the risk of infection. Reassuring the patient (D) without providing any intervention is not addressing the issue. Teaching Kegel's exercises is the most effective and non-invasive approach to manage post-TURP dribbling.

Correct Answer: B

Rationale: The correct answer is B: Dyspnea on exertion. In older clients, dyspnea on exertion is often the earliest symptom of heart failure due to decreased cardiac reserve. This occurs when the heart cannot pump enough blood to meet the body's demands during physical activity. Increased urine output (A) is not typically an early symptom of heart failure. Swollen joints (C) are more indicative of arthritis or inflammation, not necessarily heart failure. Nausea and vomiting (D) are not typical early symptoms of heart failure and are more commonly associated with gastrointestinal issues.

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.
