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 dietary approach is most beneficial for managing hypertension?

• A. Increasing caffeine intake
• B. Reducing sodium intake
• C. Increasing dietary cholesterol
• D. Reducing fiber intake

Correct answer: B

Rationale: Reducing sodium intake is the most beneficial dietary approach for managing hypertension. High sodium intake can lead to increased blood pressure, so lowering sodium intake is crucial in managing hypertension. Choices A, C, and D are incorrect because increasing caffeine intake, dietary cholesterol, or reducing fiber intake are not recommended dietary approaches for managing hypertension and may even have adverse effects on blood pressure levels.

3. In an extreme situation and when no other resident or intern is available, should a nurse receive telephone orders, the order has to be correctly written and signed by the physician within:

• A. 24 hours
• B. 36 hours
• C. 48 hours
• D. 12 hours

Correct answer: B

Rationale: In an extreme situation where no other resident or intern is available, if a nurse receives telephone orders, the order has to be correctly written and signed by the physician within 36 hours. This time frame ensures timely documentation and validation of the orders. Choice A (24 hours) is too short a period for busy physicians to fulfill the task. Choice C (48 hours) is too long and delays the incorporation of physician orders into the patient's care plan. Choice D (12 hours) may not provide enough time for the physician to review and sign the order, especially in situations where immediate attention is not required.

4. In some hip surgeries, an epidural catheter for Fentanyl epidural analgesia is given. What is your nursing priority care in such a case?

• A. Instruct the client to observe strict bed rest
• B. Check for epidural catheter drainage
• C. Administer analgesia through the epidural catheter as prescribed
• D. Assess respiratory rate carefully

Correct answer: D

Rationale: The nursing priority care in a case where an epidural catheter for Fentanyl epidural analgesia is given during hip surgeries is to assess the respiratory rate carefully. Respiratory depression is a potential side effect of Fentanyl, especially when administered epidurally. Monitoring the respiratory rate is crucial to detect any signs of respiratory distress promptly. Instructing the client to observe strict bed rest (Choice A) may be necessary but is not the priority over ensuring respiratory function. Checking for epidural catheter drainage (Choice B) and administering analgesia through the epidural catheter as prescribed (Choice C) are important aspects of care, but ensuring adequate ventilation takes precedence to prevent complications.

5. If a child has two or more pink signs, you would classify the child as having:

• A. No disease
• B. Mild form of disease
• C. Urgent Referral
• D. Very severe disease

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
