Correct Answer: C

Rationale: Idiopathic thrombocytopenic purpura is a bleeding disorder characterized by a low number of platelets in the blood. This condition is not highly similar to disseminated intravascular coagulation (DIC), which involves abnormal clotting throughout the body (coagulation), leading to depletion of platelets. Choice B is incorrect because idiopathic thrombocytopenic purpura is actually characterized by a decrease in platelet count, not an overproduction. While immune system-boosting medications may be used in some cases, the primary treatment for idiopathic thrombocytopenic purpura focuses on increasing platelet counts or managing symptoms.

Correct Answer: D

Rationale: The correct answer is D. In this scenario, since Ben took his insulin but forgot to eat, he is at risk of developing hypoglycemia. Moist skin is a sign of hypoglycemia, which can occur when blood sugar levels drop too low. Thirstiness (choice A) is more commonly associated with hyperglycemia (high blood sugar levels). Nausea (choice B) and frequent urination (choice C) are not typical immediate signs of hypoglycemia caused by missing a meal after insulin administration.

Correct Answer: A

Rationale: The correct answer is A: 'Nurses are assistants to physicians.' The public image of nurses, as portrayed by the media, often positions them as assistants to physicians. This perception stems from historical depictions and the traditional hierarchy within healthcare settings. Choice B is incorrect because it reflects how nurses perceive their patients, not how the public views nurses. Choice C is incorrect as nurses are part of the broader healthcare team but are not seen as fundamentally different from other healthcare providers by the public. Choice D is incorrect as while nurses play a crucial role in shaping healthcare, the public perception often focuses more on their supportive role in the healthcare system.

Correct Answer: B

Rationale: Student nurses, licensed practical nurses, the Vice President for nursing investigating a fall, and quality assurance nurses have a 'need to know' basis to access patient records. Registered nurses who are not directly involved in the care of a patient do not have a legitimate reason or 'need to know' to access that patient's medical records, making choice B the correct answer. The Vice President for nursing investigating a specific incident and licensed practical nurses directly involved in a patient's care have legitimate reasons to access the medical records, ensuring continuity and quality of care.

Correct Answer: A

Rationale: The correct answer is A. Having a client on airborne precautions wear a mask when out of their room is appropriate to prevent the spread of infection. Choice B is incorrect because the healthcare provider, not the client, wears an N95 respirator mask for a client on droplet precautions. Choice C is incorrect because negative-pressure airflow rooms are used for clients with airborne infections, not compromised immunity. Choice D is incorrect because visitors, not clients, should wear a mask when visiting a client on contact precautions.
