Correct Answer: B

Rationale: The correct answer is B: The waiting area with the television turned off. This setting provides a quiet environment, minimizing distractions for the patient with a hearing deficit. It allows the nurse to communicate effectively by speaking clearly and facing the patient directly. Option A is incorrect because a closed door may not be enough to reduce background noise. Option C is incorrect as pain medication may affect the patient's ability to concentrate. Option D is incorrect because the occupational therapist working on leg exercises may create additional noise and distractions.

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: D

Rationale: Step 1: Symptoms of food poisoning typically include salivation, cramping, nausea, vomiting, and diarrhea, so statement A is correct. Step 2: Food left unrefrigerated can lead to bacterial growth, making it more dangerous, so statement B is accurate. Step 3: Cooking can kill harmful organisms and stop the production of toxins, supporting statement C. Step 4: All three statements are true and collectively provide a comprehensive understanding of food poisoning, making option D the correct answer.

Correct Answer: D

Rationale: The correct answer is D because a multilumen pulmonary artery catheter can provide detailed information about preload, afterload, and cardiac output. Preload refers to the volume of blood in the ventricles at the end of diastole, afterload is the resistance the heart has to overcome to eject blood, and cardiac output is the amount of blood pumped by the heart per minute. This catheter allows for direct measurement of these parameters by monitoring pressures in the pulmonary artery. Choices A, B, and C are incorrect individually as they do not encompass the full range of information that can be obtained with a multilumen pulmonary artery catheter.

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.
