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. When providing endotracheal suctioning, for how long should the nurse suction the endotracheal tube of an intubated client on a ventilator at a time?

• A. Five seconds or less
• B. Ten seconds or less
• C. At least 30 seconds
• D. No longer than 60 seconds

Correct answer: B

Rationale: When providing endotracheal suctioning, the nurse should suction for no longer than ten seconds at a time. Suctioning for longer than ten seconds may cause hypoxia or bronchospasm. Extended suctioning may also place the client at risk of injury to the bronchial and tracheal structures. Choices C and D suggest prolonged suctioning durations that can lead to adverse effects on the client. Choice A, suctioning for five seconds or less, may not be adequate to clear secretions effectively, making choice B the most appropriate duration for safe and efficient suctioning in this scenario.

3. When caring for a patient with latex allergy, the healthcare provider creates a latex-safe environment by doing which of the following?

• A. Carefully cleaning the wall-mounted blood pressure device before using it.
• B. Donning latex gloves outside the room to limit powder dispersal.
• C. Using a latex-free pharmacy protocol.
• D. Placing the patient in a semi-private room.

Correct answer: C

Rationale: Creating a latex-safe environment for a patient with latex allergy is crucial to prevent allergic reactions. Using a latex-free pharmacy protocol is essential as it ensures that medications and supplies provided to the patient are free of latex components. Cleaning a wall-mounted blood pressure device may not be sufficient as the device itself may contain latex parts that can trigger an allergic reaction. Donning latex gloves, even outside the room, is not recommended as powder dispersal can cause issues; only non-latex gloves should be used in a latex-safe environment. Placing the patient in a semi-private room does not directly address the need to eliminate latex exposure from medical supplies and equipment, which is better achieved through a latex-free pharmacy protocol.

4. Which brain structure serves as the heat-regulating center?

• A. Hypothalamus
• B. Pituitary Gland
• C. Pons
• D. Medulla Oblongata

Correct answer: A

Rationale: The correct answer is the Hypothalamus. The hypothalamus is responsible for regulating body temperature, ensuring it stays within a narrow range. Moreover, the hypothalamus controls various essential bodily functions, such as hunger, thirst, and circadian rhythms. Choices B, C, and D are incorrect because the Pituitary Gland primarily produces and releases hormones, the Pons is involved in functions like sleep, respiration, and bladder control, and the Medulla Oblongata controls vital functions like breathing and heart rate, but not body temperature regulation.

5. A patient is asked to abduct her arms. Which of the following accurately describes her arm movement?

• A. She moves her arms away from her trunk
• B. She moves her arms toward her trunk
• C. She rotates her arms at the wrists while holding them away from her body
• D. She crosses her arms over her abdomen

Correct answer: A

Rationale: Abduction refers to moving a body part away from the midline of the body. In this case, when the patient abducts her arms, she is moving them away from her trunk. Choice A is correct. Choices B, C, and D are incorrect. Choice B describes adduction, which is the movement of a body part toward the midline. Choice C describes wrist rotation, not arm abduction. Choice D describes crossing the arms over the abdomen, which is not the movement associated with abduction.
