Correct Answer: C

Rationale: The correct answer is C because Certified Nursing Assistants (CNAs) typically provide the majority of direct patient care in nursing homes. CNAs assist with activities of daily living, monitoring patients' health, and providing emotional support. This is true in most nursing homes as they play a crucial role in patient care. Rationale: - A: Most nurses in nursing homes are not necessarily Registered Nurses (RNs), as there are also Licensed Practical Nurses (LPNs) and Certified Nursing Assistants (CNAs) who provide care. - B: LPNs or LVNs may assist with the patient care plan under the supervision of an RN, but they do not typically develop the plan themselves. - D: Staff turnover is a major issue in nursing homes due to various factors such as workload, stress, and burnout among healthcare workers.

Correct Answer: D

Rationale: The correct answer is D, "All of the above." Bill's symptoms of epigastric pain lasting 30 minutes or more can be indicative of peptic ulcer, pancreatitis, or myocardial ischemia. Peptic ulcer can cause epigastric pain, pancreatitis presents with severe epigastric pain, and myocardial ischemia can manifest as epigastric discomfort. Considering all these possibilities is crucial for proper diagnosis and treatment. The other choices are incorrect because they do not encompass all potential causes of Bill's symptoms. It is important to consider a broad differential diagnosis to ensure comprehensive evaluation and management.

Correct Answer: A

Rationale: The correct answer is A because guidelines for primary stroke prevention recommend using aspirin in individuals whose risk of stroke is high enough for the benefits to outweigh the risks. This is based on assessing individual risk factors such as age, hypertension, diabetes, smoking, and history of cardiovascular diseases to determine if the potential benefits of aspirin therapy in reducing the risk of stroke outweigh the potential risks such as gastrointestinal bleeding. Choices B, C, and D are incorrect because aspirin should not be used regardless of risk level, based on gender, or in specific populations without considering individual risk factors to ensure the benefits outweigh the risks.

Correct Answer: B

Rationale: The correct answer is B: A dull pain or cramp. In peripheral artery disease, calf pain is typically described as a dull ache or cramp due to inadequate blood flow to the muscles during exercise. This pain is known as claudication. Choice A is incorrect as sharp, stabbing pain is not typically associated with peripheral artery disease. Choice C, an electric shock, is more indicative of nerve-related conditions. Choice D, a pulsating pain, is more characteristic of an aneurysm rather than peripheral artery disease.

Correct Answer: A

Rationale: The correct answer is A: Papilledema. Diabetic retinopathy is a microvascular complication of diabetes that primarily affects the retina's blood vessels. Papilledema, which is optic disc swelling due to increased intracranial pressure, is not a typical finding in diabetic retinopathy. Dot and blot hemorrhages, microaneurysms, and cotton wool spots are commonly seen in diabetic retinopathy due to retinal vessel damage and ischemia. Papilledema is more associated with conditions like intracranial hypertension or optic neuritis.
