Nursing Elites

1. Which of the following statements is false?

• A. People with a vitamin K deficiency experience increased clotting time
• B. The major function of vitamin E is promoting vision
• C. Vitamin D functions as a hormone
• D. Rich sources of beta-carotene include carrots, sweet potatoes, and butternut squash

Correct answer: B

Rationale: The statement that the major function of vitamin E is promoting vision is incorrect. Vitamin E primarily acts as an antioxidant, protecting cells from oxidative damage. Its role is not primarily related to vision, which is a major function of vitamin A. On the other hand, the other options are true. Vitamin K deficiency does indeed lead to increased clotting time, vitamin D functions as a hormone, and carrots, sweet potatoes, and butternut squash are rich sources of beta-carotene.

2. After bronchoscopy, the nurse's priority is to check which of the following before feeding?

• A. Gag reflex
• B. Wearing off of anesthesia
• C. Swallowing reflex
• D. Peristalsis

Correct answer: A

Rationale: After a bronchoscopy procedure, the nurse's priority is to check the patient's gag reflex before allowing them to eat to prevent aspiration. The gag reflex helps protect the airway by triggering a cough or gag response if something touches the back of the throat. This is crucial to ensure that the patient can protect their airway and prevent food or fluids from entering the lungs, especially when the throat may be sensitive or compromised post-bronchoscopy. Checking for the wearing off of anesthesia, swallowing reflex, or peristalsis are important assessments but not the immediate priority before feeding in this context.

3. A patient who is recovering from surgery should increase their intake of which nutrient to promote healing?

• A. Fats
• B. Carbohydrates
• C. Protein
• D. Fiber

Correct answer: C

Rationale: Protein is crucial for tissue repair and recovery after surgery. Proteins provide the building blocks necessary for tissue healing and regeneration. Fats are important for various bodily functions but are not as directly involved in tissue repair as proteins. Carbohydrates provide energy but do not play a primary role in tissue healing. Fiber is essential for digestive health but is not a nutrient that directly promotes tissue repair.

4. Weight loss therapies that rely on juicing typically provide increased fiber, vitamins, and minerals. As an added incentive, juices contain a lower concentration of sugar than the whole fruit. Are these statements true or false?

• A. Both statements are true
• B. Both statements are false
• C. The first statement is true; the second is false
• D. The first statement is false; the second is true

Correct answer: B

Rationale: The correct answer is both statements are false. The process of juicing often extracts the liquid components of fruits and vegetables, leaving behind the fiber-rich pulp. Therefore, juicing does not typically provide increased fiber. Additionally, juices can contain a higher concentration of sugar than whole fruits because the fiber, which helps to slow down the absorption of sugar, has been removed. This can lead to a spike in blood sugar levels after consumption. The other options are incorrect because they contain at least one false statement.

5. What is the role of fat in digestion?

• A. Digest fats in the stomach
• B. Emulsify fats in the small intestine
• C. Transport fats through the circulatory system
• D. Split fats into smaller components

Correct answer: B

Rationale: The correct answer is B: Emulsify fats in the small intestine. Bile emulsifies fats in the small intestine, breaking them down into smaller droplets that can be more easily digested by enzymes like lipase. Choice A is incorrect as fats are not digested in the stomach but rather in the small intestine. Choice C is incorrect as fats are transported through the lymphatic system instead of the circulatory system. Choice D is incorrect as fats are broken down into smaller components through emulsification, not splitting.
