ATI RN Custom Exams Set 4
1. 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.
2. What is an initial sign of nephrosis that the nurse might note in a child?
- A. Raspberry-like rash
- B. Periorbital edema
- C. Temperature elevation
- D. Abdominal pain
Correct answer: B
Rationale: In nephrotic syndrome, edema is a common symptom that is generalized and not easily noticeable, even by parents. However, an early sign that can be assessed by the nurse is periorbital edema, which refers to swelling around the eyes. This can be an initial indicator of nephrosis and may prompt further evaluation and intervention.
3. A client takes atorvastatin (Lipitor), with laboratory results showing a blood urea nitrogen (BUN) of 33 mg/dL and creatinine of 2.8 mg/dL. What action by the nurse is best?
- A. Ask if the client eats grapefruit.
- B. Assess the client for dehydration.
- C. Facilitate admission to the hospital.
- D. Obtain a random urinalysis.
Correct answer: A
Rationale: There is a drug-food interaction between statins and grapefruit that can lead to acute kidney failure. The client has elevated renal laboratory results, indicating kidney involvement. The nurse should ask if the client consumes grapefruit or grapefruit juice. While dehydration can elevate BUN, the increase in creatinine is more specific for kidney injury.
4. A nurse is caring for a client who is receiving furosemide. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the medication?
- A. Serum sodium.
- B. Serum glucose.
- C. Serum potassium.
- D. Serum calcium.
Correct answer: C
Rationale: The correct answer is C: Serum potassium. Furosemide is a potassium-wasting diuretic, meaning it can lead to potassium loss in the body. Monitoring serum potassium levels is crucial to evaluate the effectiveness of furosemide and prevent hypokalemia. Options A, B, and D are incorrect because furosemide does not directly affect sodium, glucose, or calcium levels in the same way it impacts potassium levels.
5. A nurse is caring for a client who reports difficulty falling asleep. Which of the following recommendations should the nurse make?
- A. Watch a television program in bed before going to sleep.
- B. Drink a cup of hot cocoa before bedtime.
- C. Maintain a consistent time to wake up each day.
- D. Exercise 1 hour before going to bed.
Correct answer: C
Rationale: The correct answer is C: "Maintain a consistent time to wake up each day." Establishing a regular wake-up time helps regulate the body's internal clock and promotes better sleep patterns. Watching television in bed (Choice A) can actually hinder sleep due to the light emitted by screens affecting melatonin production. Drinking beverages with caffeine like hot cocoa (Choice B) close to bedtime can interfere with falling asleep. Exercising vigorously right before bed (Choice D) can increase alertness and make it harder to fall asleep.
