1. Which of the following is a fat-soluble vitamin?

A. Vitamin C
B. Vitamin D
C. Vitamin B-6
D. Riboflavin

Correct answer: B

Rationale: The correct answer is Vitamin D. Fat-soluble vitamins are those that can be stored in the body, allowing excess amounts to be stored for later use. While this storage ability can help prevent deficiencies, it also poses a risk of toxicity. The fat-soluble vitamins are A, E, D, and K. Choice A, Vitamin C, is water-soluble, not fat-soluble. Choice C, Vitamin B-6, and Choice D, Riboflavin, are also water-soluble vitamins and not fat-soluble.

2. A healthcare professional is asked to draw blood in the antecubital (AC) space. Which of the following veins are found in the AC?

A. Cephalic
B. Median cubital
C. Basilic
D. All of the above

Correct answer: D

Rationale: The correct answer is 'All of the above.' All three of these veins - the cephalic, median cubital, and basilic veins - are located in the antecubital space, which is the area in front of the elbow on the arm. The cephalic vein runs along the outer side of the arm, the basilic vein runs along the inner side of the arm, and the median cubital vein is a connecting vein between the cephalic and basilic veins. Therefore, all three veins can be accessed when drawing blood from the antecubital space. Choices A, B, and C are incorrect because each of these veins individually can be found in the antecubital space.

3. The nurse is reviewing percussion techniques with a new graduate nurse. Which action performed by the graduate nurse while percussing requires the nurse to intervene?

A. Percussing twice over each area
B. Striking with the fingertip, not the finger pad
C. Using the wrist to make the strikes, not the arm
D. Quickly lifting the striking finger after each stroke

Correct answer: A

Rationale: The correct answer is to percuss twice over each area, not once. This technique helps ensure a more accurate assessment. Striking with the fingertip instead of the finger pad is correct because the tip of the finger produces clearer sounds. Using the wrist to make the strikes instead of the arm is appropriate as it allows for more controlled and precise percussion. Quickly lifting the striking finger after each stroke is also correct to prevent damping off vibrations. Therefore, percussing once over each area (Choice A) is incorrect as it does not follow the standard percussion technique.

4. What is the primary route of transmission of MRSA?

A. Shared needles
B. Hands of healthcare workers
C. Items in the healthcare environment
D. Blood transfusions

Correct answer: B

Rationale: The correct answer is 'Hands of healthcare workers.' MRSA is primarily transmitted via the unwashed hands of healthcare workers who can carry the Staphylococcus aureus bacterium from one patient to another. Shared needles, items in the healthcare environment, and blood transfusions are not the main routes of transmission for MRSA. Shared needles can transmit bloodborne pathogens, items in the healthcare environment can harbor bacteria but are not the primary mode for MRSA, and blood transfusions are not a common route for MRSA transmission.

5. What is the primary purpose of a patient care meeting or conference?

A. the patient's ability to pay for the costs of their care
B. how the healthcare team can best meet the patient's needs
C. the patient's physical status and condition
D. the patient's psychosocial status and condition

Correct answer: B

Rationale: The primary purpose of a patient care meeting or conference is to determine how the healthcare team can best meet the patient's needs. These meetings involve discussions among healthcare professionals to tailor the care plan to the specific needs and preferences of the patient. Option A is incorrect because financial discussions are generally not the primary focus of patient care meetings. Option C is incorrect as the patient's physical status is usually already known and is not the primary purpose of the meeting. Option D is incorrect as psychosocial aspects, while important, are not the sole focus of the meeting, which is primarily about addressing the patient's overall needs and preferences.
