ATI Nutrition Proctored Exam 2023
1. What is a major constituent of cell membranes?
- A. cholesterol
- B. phospholipid
- C. saturated
- D. triglyceride
Correct answer: B
Rationale: Phospholipids are a major component of cell membranes, providing structural integrity and facilitating cell signaling. Cholesterol (choice A) is also present in cell membranes but in smaller amounts and plays a different role. Saturated (choice C) and triglyceride (choice D) are not major constituents of cell membranes.
2. A client has a new prescription for Enalapril. Which of the following adverse effects should the nurse monitor?
- A. Dry cough
- B. Weight gain
- C. Diarrhea
- D. Nausea
Correct answer: A
Rationale: The correct answer is A: Dry cough. A persistent dry cough is a common adverse effect of Enalapril, an ACE inhibitor. Enalapril can cause the accumulation of bradykinin, leading to cough. Monitoring for a persistent dry cough is crucial as it may indicate the need for further evaluation and possible medication adjustment. Choices B, C, and D are not typically associated with Enalapril use and are less likely to be monitored as adverse effects.
3. Which enzyme is most essential for hydrolyzing large protein molecules?
- A. Gastric lipase
- B. Pepsin
- C. Mucus
- D. Intrinsic factor
Correct answer: B: Pepsin
Rationale: Pepsin, choice B, is the correct answer as it is a proteolytic enzyme that is essential for the breakdown of large protein molecules in the stomach. Gastric lipase, choice A, is incorrect because it primarily targets fats, not proteins, hence it is not involved in protein hydrolysis. Mucus, choice C, is incorrect as it serves to protect the stomach lining from acidic gastric juices and does not play a direct role in protein digestion. Intrinsic factor, choice D, is incorrect as it is vital for the absorption of Vitamin B12 in the small intestine and doesn't participate in the process of hydrolyzing proteins.
4. Which surgical procedure involves opening or replacing a narrowed or blocked heart valve?
- A. Valve replacement
- B. Angioplasty
- C. Stent placement
- D. Coronary bypass surgery
Correct answer: A
Rationale: Valve replacement is the correct answer because it specifically involves surgically replacing a damaged or diseased heart valve with a prosthetic valve to address narrowing or blockage, thereby improving blood flow and heart function. Angioplasty (choice B) is a procedure to widen narrowed or obstructed arteries, typically using a balloon catheter. Stent placement (choice C) involves inserting a mesh tube to support a weakened artery. Coronary bypass surgery (choice D) is a procedure to create new routes for blood flow to the heart muscle by bypassing blocked arteries.
5. A patient is taking a statin for hyperlipidemia. What important instruction should the nurse provide to the patient?
- A. Take the medication at night to avoid muscle pain.
- B. Take the medication in the morning to ensure it works throughout the day.
- C. Avoid consuming alcohol while taking this medication.
- D. Take the medication with a high-fat meal to increase absorption.
Correct answer: A
Rationale: The correct answer is to instruct the patient to take the medication at night to avoid muscle pain. Statins are known to potentially cause muscle pain or weakness; taking the medication at night can help reduce the incidence of these side effects. Option B is incorrect because the timing of statin administration is not related to its effectiveness throughout the day. Option C is a general precaution when taking medications but not the most important instruction specific to statins. Option D is incorrect as taking the medication with a high-fat meal can actually decrease its absorption.
