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.

During a physical assessment of a newborn, which of the following findings should the nurse prioritize reporting?
- A. Head circumference of 40 cm
- B. Chest circumference of 32 cm
- C. Acrocyanosis and edema of the scalp
- D. Heart rate of 160 bpm and respirations of 40/min
Correct Answer: A
Rationale: The correct answer is A. A head circumference of 40 cm is abnormally large for a newborn and could indicate conditions like hydrocephalus or other abnormalities, making it a crucial finding to report. Choices B, C, and D are within normal parameters for a newborn and do not pose immediate concerns. Chest circumference of 32 cm is a normal finding. Acrocyanosis and edema of the scalp are common in newborns due to physiological adaptations. A heart rate of 160 bpm and respirations of 40/min may be within the normal range for a newborn.
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 crucial for clients on furosemide (Lasix) to prevent hypokalemia, as furosemide can cause potassium loss. White bread (choice B) and scrambled egg (choice D) are not high-potassium foods and do not address the specific need related to furosemide therapy. While apples (choice C) contain some potassium, they are not as rich in potassium as a baked potato, making them a less optimal choice for a client on furosemide.
The nurse is caring for a client who goes into ventricular tachycardia. Which intervention should the nurse implement first?
- A. Call a code immediately
- B. Assess the client for a pulse
- C. Begin chest compressions
- D. Continue to monitor the client
Correct Answer: B
Rationale: The correct answer is to assess the client for a pulse. In ventricular tachycardia, the priority is to determine if the client has a pulse. If there is no pulse, immediate initiation of CPR with chest compressions is required. Calling a code or continuing to monitor the client can delay life-saving interventions. Therefore, assessing for a pulse is the most crucial step in managing ventricular tachycardia.
The nurse is caring for clients on a medical floor. Which client will the nurse assess first?
- A. The client with an abdominal aortic aneurysm who is constipated
- B. The client on bed rest who ambulated to the bathroom
- C. The client with essential hypertension who has epistaxis and a headache
- D. The client with arterial occlusive disease who has a decreased pedal pulse
Correct Answer: C
Rationale: The correct answer is C because epistaxis and headache in a client with hypertension are signs of a hypertensive crisis that necessitate immediate intervention. Choice A is incorrect as constipation in a client with an abdominal aortic aneurysm, while important, does not indicate an immediate crisis. Choice B is incorrect as a client on bed rest ambulating to the bathroom is a positive sign. Choice D is incorrect because a decreased pedal pulse in arterial occlusive disease should be addressed promptly, but it does not indicate an acute emergency like a hypertensive crisis.
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.
