Nursing Elites

1. Three major causes of atherosclerosis are:

• A. Hyperthyroidism, underweight, and poor appetite
• B. High blood cholesterol, high blood pressure, and cigarette smoking
• C. Constipation, peptic ulcer disease, and pancreatitis
• D. Kidney failure, edema, and sodium retention

Correct answer: B

Rationale: Atherosclerosis is primarily caused by high blood cholesterol, high blood pressure, and cigarette smoking. These factors contribute to the buildup of plaque in the arteries. Choices A, C, and D are incorrect. Hyperthyroidism, underweight, and poor appetite do not directly cause atherosclerosis. Similarly, constipation, peptic ulcer disease, pancreatitis, kidney failure, edema, and sodium retention are not among the primary causes of atherosclerosis.

2. The nurse supervises care of a client who is receiving enteral feeding via a nasogastric tube. The nurse determines that care is appropriate if which of the following is observed? (Select all that apply)

• A. The nursing assistant aspirates and measures the amount of the gastric aspirate
• B. The nursing assistant elevates the head of the client’s bed 30 degrees
• C. The nursing assistant warms the formula to room temperature
• D. B, C

Correct answer: D

Rationale: Elevating the head of the bed to 30 degrees reduces the risk of aspiration by promoting proper digestion and preventing reflux. Warming the formula to room temperature is essential to prevent discomfort and complications. Aspirating and measuring the gastric aspirate is not a recommended nursing action for monitoring enteral feeding via a nasogastric tube, as it can introduce the risk of introducing contaminants into the feeding tube. Therefore, choices A and B are incorrect, making choice D the correct answer.

3. The nurse is aware that norepinephrine is secreted by which endocrine gland?

• A. The pancreas
• B. The adrenal cortex
• C. The adrenal medulla
• D. The anterior pituitary gland

Correct answer: C

Rationale: Norepinephrine is indeed secreted by the adrenal medulla, making choice C the correct answer. The adrenal medulla is part of the adrenal glands, located on top of the kidneys. Norepinephrine is involved in the body's 'fight or flight' response, helping to prepare the body to react to stress. Choices A, B, and D are incorrect as norepinephrine is not secreted by the pancreas, adrenal cortex, or the anterior pituitary gland.

4. What causes hepatic encephalopathy?

• A. Buildup of ammonia in the body
• B. Buildup of urea in the body
• C. Fatty infiltration of the liver
• D. Jaundice

Correct answer: A

Rationale: Hepatic encephalopathy is caused by the buildup of ammonia in the body. Ammonia, a byproduct of protein metabolism, normally gets converted to urea in the liver for excretion. However, in liver dysfunction, such as cirrhosis, the liver cannot effectively convert ammonia to urea, leading to its accumulation in the body and subsequently causing hepatic encephalopathy. Choices B, C, and D are incorrect as they do not directly relate to the pathophysiology of hepatic encephalopathy.

5. What is the mission of the Army Medical Department?

• A. Ensure that each soldier receives a physical examination annually
• B. Deliver healthcare to regions of the U.S. designated as disaster areas by the President
• C. Maintain the health of the Army and preserve its combat effectiveness
• D. Offer medical, dental, and veterinary education and training

Correct answer: C

Rationale: The correct answer is C: 'Maintain the health of the Army and preserve its combat effectiveness.' This mission statement reflects the primary goal of the Army Medical Department, which is to ensure that military personnel remain healthy and fit for duty to preserve the Army's fighting strength. Choices A, B, and D are incorrect because they do not capture the core purpose of the Army Medical Department, which is focused on the health and readiness of the military forces, rather than performing annual physical examinations, responding to disasters, or providing education and training.
