Nursing Elites

1. During the detoxification stage, it is a priority for the nurse to:

• A. teach skills to recognize and respond to health threatening situations
• B. increase the client’s awareness of unsatisfactory protective behaviors
• C. implement behavior modification
• D. promote homeostasis and minimize the client’s withdrawal symptoms

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.

2. Which vitamin deficiency is most likely to cause bleeding disorders?

• A. Vitamin A
• B. Vitamin E
• C. Vitamin K
• D. Vitamin D

Correct answer: C

Rationale: Vitamin K is essential for blood clotting as it plays a crucial role in the activation of clotting factors. Deficiency of Vitamin K can lead to impaired blood clotting, resulting in bleeding disorders. Vitamin A is more associated with vision and skin health, not blood clotting. Vitamin E is known for its antioxidant properties and role in immune function, not specifically related to bleeding disorders. Vitamin D plays a key role in calcium absorption and bone health, but it is not directly linked to blood clotting or bleeding disorders.

3. Which dietary recommendation is most appropriate for a patient with gout?

• A. Increase protein intake
• B. Reduce carbohydrate intake
• C. Avoid purine-rich foods
• D. Increase calcium intake

Correct answer: C

Rationale: The most appropriate dietary recommendation for a patient with gout is to avoid purine-rich foods. Purine-rich foods such as red meat and shellfish can lead to increased uric acid levels in the body, triggering gout flare-ups. Increasing protein intake (Choice A) is not recommended as some high-protein foods are also high in purines. Reducing carbohydrate intake (Choice B) and increasing calcium intake (Choice D) are not directly related to managing gout symptoms.

4. 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.

5. Which physiologic role does vitamin C play in the body?

• A. Transcribing DNA to RNA
• B. Absorption and regulation of calcium
• C. Protects integrity of cellular membranes
• D. Catalyst for synthesis of blood-clotting factors

Correct answer: C

Rationale: Vitamin C plays a crucial role in protecting the integrity of cellular membranes. It is essential for collagen synthesis, which is important for wound healing and maintaining skin, blood vessels, and other tissues. Choice A is incorrect as the transcription of DNA to RNA is facilitated by vitamin A. Choice B is incorrect as calcium absorption and regulation are functions of vitamin D. Choice D is incorrect as vitamin K serves as a catalyst for the synthesis of blood-clotting factors, not vitamin C.
