1. Which vitamin is also known as Niacin?

• A. Vitamin B1
• B. Vitamin B2
• C. Vitamin B3
• D. Vitamin B12

Correct answer: C

Rationale: The correct answer is Vitamin B3, also known as Niacin. Niacin is essential for energy metabolism and can help improve cholesterol levels. Vitamin B1 is Thiamine, Vitamin B2 is Riboflavin, and Vitamin B12 is Cobalamin. These vitamins have different functions in the body and are not synonymous with Niacin.

2. Earliest sign of skin reaction to radiation therapy is:

• A. desquamation
• B. erythema
• C. atrophy
• D. pigmentation

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.

3. A nurse is providing teaching to a group of parents of newborns who are planning to formula feed. Which of the following statements by a parent indicates a need for further teaching?

• A. "I will give formula to my baby at room temperature."
• B. "I will ensure my baby's feeds last 10 to 15 minutes."
• C. "I will burp my baby halfway through each feeding."
• D. "I will watch for signs my baby is full and stop the feeding."

Correct answer: B

Rationale: The correct answer is, "I will ensure my baby's feeds last 10 to 15 minutes." This statement indicates a need for further teaching because it suggests a strict time limit for feedings, which may not be appropriate for a newborn. Newborns should be allowed to feed as long as they want, typically around 20-30 minutes per breast if breastfeeding, or on-demand with formula. Choices A, C, and D demonstrate proper feeding practices such as feeding at room temperature, burping halfway through each feeding, and watching for signs of fullness to stop the feeding, which are all appropriate responses by a parent of a formula-fed newborn.

4. Health practitioners evaluate disease progression in HIV-infected patients by measuring the concentrations of helper T cells and circulating virus, called _____.

• A. cross resistance
• B. the immune response
• C. acquired resistance
• D. the viral load

Correct answer: D

Rationale: The viral load is the measure of the amount of circulating virus in the blood and is used to evaluate the progression of HIV infection.

5. Where should a nurse auscultate the apex beat?

• A. At the fifth intercostal space, along the midclavicular line
• B. At the mid-sternum
• C. 2 inches to the left of the lower end of the sternum
• D. 1 inch to the left of the xiphoid process

Correct answer: A

Rationale: The correct location to auscultate the apex beat is at the fifth intercostal space, along the midclavicular line. This is where the apical impulse, also known as the point of maximal impulse (PMI), can be best heard. Choices B, C, and D are incorrect anatomical locations for auscultating the apex beat, which makes them incorrect choices. Auscultating at the correct location allows healthcare providers to assess the heart's function and detect any abnormalities in heart sounds, which is crucial for comprehensive patient care.
