Nursing Elites

1. Each statement is true of vitamin K, except one. Which is the exception?

• A. Vitamin K is produced in the gut.
• B. Vitamin K functions as a catalyst for the synthesis of blood-clotting factors.
• C. Vitamin K maintains prothrombin levels.
• D. Vitamin K absorption increases with high levels of vitamin E supplementation.

Correct answer: D

Rationale: The correct answer is D. Vitamin K absorption decreases with high levels of vitamin E supplementation because in larger amounts, vitamin E acts as an anticoagulant. Vitamin K is not produced in the gut but can be obtained from food sources or supplements. Vitamin K is essential for the synthesis of blood-clotting factors and is crucial in maintaining prothrombin levels, which is vital for proper blood clotting. The incorrect choice, D, is misleading as high levels of vitamin E supplementation hinder vitamin K absorption due to its anticoagulant properties. Dental hygienists should be aware of the importance of vitamin K in blood clotting, especially when treating patients who are on anticoagulant medications for conditions like stroke prevention.

2. Which practice is a type of traditional Chinese medicine?

• A. magnet therapy
• B. acupuncture
• C. faith healing
• D. biofeedback

Correct answer: B

Rationale: Acupuncture is a key practice in traditional Chinese medicine. It involves the insertion of thin needles into specific points on the body to balance energy flow and promote healing. Magnet therapy, faith healing, and biofeedback are not specifically associated with traditional Chinese medicine practices.

3. A nurse is planning care for a client who reports increasing difficulty swallowing food. Which of the following interventions should the nurse plan to take?

• A. Turn on the client’s television during meals.
• B. Place the client into a semi-reclining position for meals.
• C. Encourage the client to rest prior to mealtimes.
• D. Encourage the client to use a straw when drinking liquids.

Correct answer: C

Rationale: The correct answer is to encourage the client to rest prior to mealtimes. This intervention can help reduce fatigue and improve the ability to swallow. Turning on the client’s television during meals (choice A) may distract the client but does not directly address the swallowing issue. Placing the client into a semi-reclining position for meals (choice B) can help with swallowing difficulties, but resting before meals is more beneficial. Encouraging the client to use a straw when drinking liquids (choice D) is not the priority intervention for swallowing difficulties in this scenario.

4. A patient who reports stomach ulcers should avoid all the following foods, except one. Which is the exception?

• A. Proteins
• B. Caffeine
• C. Calcium
• D. Wheat

Correct answer: D

Rationale: Patients with stomach ulcers are advised to avoid foods that can increase stomach acid levels, such as caffeine, proteins, and calcium. Wheat, on the other hand, is generally well-tolerated by individuals with ulcers as it does not stimulate gastric secretions. Therefore, the correct answer is D. Choice A (Proteins), B (Caffeine), and C (Calcium) are not recommended for patients with stomach ulcers due to their potential to exacerbate symptoms.

5. Which biomolecule is responsible for the storage and transfer of genetic information?

• A. Carbohydrates
• B. Proteins
• C. Lipids
• D. Nucleic acids

Correct answer: D

Rationale: Nucleic acids, such as DNA and RNA, are the biomolecules responsible for storing and transferring genetic information within cells. Carbohydrates, proteins, and lipids do not have this specific function. Carbohydrates are mainly used for energy storage, structural support, and cellular communication. Proteins are involved in various cellular functions such as enzymatic reactions, structural support, and signaling. Lipids play roles in energy storage, cell membrane structure, and signaling.
