Nursing Elites

1. The type of lipoprotein that carries cholesterol from tissues to the liver for excretion is:

• A. Very low-density lipoprotein
• B. Intermediate-density lipoprotein
• C. Low-density lipoprotein
• D. High-density lipoprotein

Correct answer: D

Rationale: The correct answer is D, High-density lipoprotein (HDL). HDL is known as the 'good' cholesterol and plays a crucial role in transporting cholesterol from tissues back to the liver for excretion. This process helps in reducing the buildup of cholesterol in the bloodstream, thus lowering the risk of heart diseases. Very low-density lipoprotein (Option A), Intermediate-density lipoprotein (Option B), and Low-density lipoprotein (Option C) are not responsible for carrying cholesterol back to the liver for excretion like HDL does. Instead, they are associated with different functions related to cholesterol transportation within the body.

2. The nurse cares for a client receiving furosemide (Lasix). The nurse determines that teaching is effective if the client selects which of the following foods?

• A. One medium baked potato
• B. One slice of white bread
• C. One medium apple
• D. One scrambled egg

Correct answer: A

Rationale: The correct answer is A: One medium baked potato. Potatoes are high in potassium, which is essential for clients on Lasix to prevent hypokalemia. Furosemide is a loop diuretic that can cause potassium depletion, so consuming potassium-rich foods like baked potatoes can help maintain normal potassium levels. Choices B, C, and D do not provide a significant source of potassium, which is crucial for clients on furosemide therapy.

3. Under the health services support area concept, how is the medical care under the MEDCOM divided?

• A. Six geographical regions of the United States with command authority in each region
• B. Five levels of health service support, each providing different levels of health care services
• C. Primary and secondary health care regions, each containing a MEDDAC or MEDCEN
• D. Eight geographical areas of responsibility designated as health services support regions, each of which is subdivided into two or more health service areas

Correct answer: D

Rationale: The correct answer is D. Under the health services support area concept, the medical care under the MEDCOM is divided into eight geographical areas of responsibility designated as health services support regions, each of which is further subdivided into two or more health service areas. This structure allows for a more organized and efficient delivery of medical care across different regions. Choices A, B, and C are incorrect because they do not accurately describe how medical care under the MEDCOM is divided according to the concept of health services support areas.

4. Which lipoprotein carries cholesterol from tissues to the liver for excretion?

• A. Very low-density lipoprotein
• B. Intermediate-density lipoprotein
• C. Low-density lipoprotein
• D. High-density lipoprotein

Correct answer: D

Rationale: The correct answer is D, High-density lipoprotein (HDL). HDL is known as 'good' cholesterol because it helps transport excess cholesterol from tissues back to the liver for removal from the body. Very low-density lipoprotein (VLDL) (choice A) and intermediate-density lipoprotein (choice B) are involved in transporting triglycerides. Low-density lipoprotein (LDL) (choice C) is known as 'bad' cholesterol as it can deposit cholesterol in the walls of arteries.

5. The nurse is caring for the client recovering from a percutaneous renal biopsy. Which data indicate that the client is complying with client teaching?

• A. The client lies flat in the supine position for 12 hours
• B. The client continues oral fluids restriction while on bed rest
• C. The client’s family changed the dressing on return to the room
• D. The family activates the patient-controlled analgesia pump

Correct answer: A

Rationale: The correct answer is A. Lying flat in the supine position for 12 hours after a renal biopsy is essential to prevent bleeding and promote recovery. This position helps apply pressure to the biopsy site, reducing the risk of bleeding. Choices B, C, and D are incorrect because continuing oral fluids restriction, changing the dressing, and activating the patient-controlled analgesia pump do not directly indicate compliance with the crucial post-biopsy teaching of maintaining the supine position.
