1. Which topical antimicrobial is most frequently used in burn wound care?

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

2. Which enzyme is most essential for hydrolyzing large protein molecules?

Correct answer: B

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.

3. Which food items should be avoided by a child with lactose intolerance?

Correct answer: B

Rationale: The correct answer is B: Milk, cheese, ice cream, and puddings should be avoided by a child with lactose intolerance because they contain lactose, which the child's body may have difficulty digesting. Option A is incorrect as popcorn, seeds, and foods containing nuts do not typically contain lactose. Option C lists wheat, rye, barley, and commercially baked goods, which are sources of gluten, not lactose. Option D includes eggs, ham, bacon, and canned meats, which are also not sources of lactose. Therefore, B is the most appropriate choice for a child with lactose intolerance.

4. Which of the following terms describes the amount of blood ejected per heartbeat?

Correct answer: A

Rationale: The correct answer is A: Stroke volume. Stroke volume refers to the amount of blood ejected by the left ventricle in one contraction. Choice B, Cardiac output, is the total volume of blood pumped by the heart per minute and is calculated by multiplying stroke volume by heart rate. Choice C, Ejection fraction, is the percentage of blood pumped out of the left ventricle with each heartbeat. Choice D, Afterload, refers to the pressure or resistance that the ventricles must overcome to eject blood during systole. Therefore, in the context of the question, the term that specifically describes the amount of blood ejected per heartbeat is stroke volume.

5. Larry, 55 years old, who is suspected of having colorectal cancer, is admitted to the CI. After taking the history and vital signs the physician does which test as a screening test for colorectal cancer.

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
