1. What is the function of villi and microvilli in the GI tract?
- A. produce bile
- B. kill bacteria
- C. produce vitamin K
- D. increase the surface area for absorption
Correct answer: D
Rationale: Villi and microvilli in the GI tract serve to increase the surface area of the small intestine, aiding in the absorption of nutrients into the bloodstream. Choices A, B, and C are incorrect as villi and microvilli are primarily involved in enhancing absorption, not in producing bile, killing bacteria, or producing vitamin K.
2. On the study “effects of effective nurse-patient communication in decreasing anxiety of post operative patients†What is the Dependent variable?
- A. Effective Nurse-patient communication
- B. Communication
- C. Anxiety level
- D. Post operative patient
Correct answer: B
Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.
3. After cleaning the abrasions and applying antiseptic, the nurse applies a cold compress to the swollen ankle as ordered by the physician. This statement shows that the nurse has a correct understanding of the use of a cold compress:
- A. Cold compress reduces blood viscosity in the affected area
- B. It is safer to apply than a hot compress
- C. Cold compress prevents edema and reduces pain
- D. It eliminates toxic waste products due to vasodilation
Correct answer: C
Rationale: The correct understanding of using a cold compress includes knowing that it helps prevent edema and reduces pain. Cold application constricts blood vessels, reducing blood flow to the area, which helps decrease swelling and pain. Choices A, B, and D are incorrect because cold compresses do not directly affect blood viscosity, safety compared to hot compresses, or eliminate toxic waste products due to vasodilation. It is essential for nurses to have a clear understanding of the rationale behind interventions to provide effective patient care.
4. You will do nasopharyngeal suctioning on Mr. Abad. Your guide for the length of insertion of the tubing for an adult would be:

- B. the distance from the tip of the nose to the middle of the neck
- C. the distance from the tip of the nose to the tip of the ear lobe
- D. eight to ten inches
Correct answer: D
Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
5. A nurse is reviewing blood glucose values for a client who is at risk for Diabetes Mellitus. Which of the following findings should the nurse report to the provider?
- A. 2-hour glucose tolerance test level 150 mg/dL
- B. Fasting blood glucose 70 mg/dL
- C. Glycosylated hemoglobin 5%
- D. Casual blood glucose 90 mg/dL
Correct answer: A
Rationale: The correct answer is A. A 2-hour glucose tolerance test level of 150 mg/dL is above the normal range and should be reported to the provider as it indicates impaired glucose tolerance. Choice B (Fasting blood glucose 70 mg/dL) is within the normal range. Choice C (Glycosylated hemoglobin 5%) is also within the normal range. Choice D (Casual blood glucose 90 mg/dL) is within the normal range and does not indicate impaired glucose tolerance.
