Nursing Elites

1. Where in the body are microvilli located, facilitating the absorption of most nutrients?

• A. Stomach
• B. Pancreas
• C. Large Intestine
• D. Small Intestine

Correct answer: D

Rationale: The correct answer is D: Small Intestine. Microvilli are present in the small intestine, significantly increasing its surface area for efficient absorption of nutrients. The small intestine is the primary site for nutrient absorption in the body. The stomach (choice A) primarily functions to break down food with its acidic environment but is not where most nutrients are absorbed. The pancreas (choice B) produces enzymes to aid in digestion but does not directly absorb nutrients. The large intestine (choice C) mainly absorbs water and electrolytes from undigested food, rather than nutrients.

2. What type of drug is lamivudine, used for the management of HIV infection?

• A. CCR5 antagonist
• B. fusion inhibitor
• C. nucleoside reverse transcriptase inhibitor
• D. protease inhibitor

Correct answer: C

Rationale: Lamivudine belongs to the class of nucleoside reverse transcriptase inhibitors (NRTIs), making choice C the correct answer. NRTIs like lamivudine work by inhibiting the reverse transcriptase enzyme, an essential component for the HIV virus to replicate. Choices A, B, and D are incorrect because lamivudine does not function as a CCR5 antagonist, fusion inhibitor, or protease inhibitor in the management of HIV infection.

3. A client with nephropathy secondary to diabetes mellitus is receiving dietary teaching from a nurse and plans to make dietary adjustments. Which of the following instructions should the nurse include?

• A. Consume less than 45% of total calories from carbohydrates per day.
• B. Eat no more than 300 mg of cholesterol per day.
• C. Consume less than 0.8 g/kg of body weight of protein per day.
• D. Eat at least 45 g of fiber per day.

Correct answer: D

Rationale: For a client with nephropathy secondary to diabetes mellitus, increasing fiber intake is essential as it can help manage blood sugar levels and improve overall bowel health. Choice A is incorrect because carbohydrates should be controlled but not limited to less than 45% of total calories. Choice B is incorrect as the recommended daily cholesterol intake for individuals with diabetes is less than 200 mg. Choice C is incorrect as protein intake should be individualized based on the client's condition and should not be limited to less than 0.8 g/kg of body weight per day.

4. Mang Caloy is scheduled to have a hemorrhoidectomy, after the operation, you would expect that the client’s position post operatively will be:

• A. Knee chest position
• B. Side lying position
• C. Sims position
• D. Genopectoral position

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. When performing endotracheal suctioning, the nurse applies suctioning while withdrawing and gently rotating the catheter 360 degrees for which of the following time periods?

• A. 10-15 seconds
• B. 30-35 seconds
• C. 20-25 seconds
• D. 0-5 seconds

Correct answer: D

Rationale: During endotracheal suctioning, the nurse should apply suctioning while withdrawing and gently rotating the catheter 360 degrees for a short period of 0-5 seconds. This brief duration helps minimize the risk of hypoxia and trauma to the airway. Choices A, B, and C suggest longer time periods for suctioning, which can increase the risk of complications such as hypoxia, mucosal damage, and the removal of excess amounts of airway secretions.
