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. In a patient with chronic kidney disease, which dietary modification is recommended?

• A. Increase protein intake
• B. Reduce potassium intake
• C. Increase sodium intake
• D. Reduce fiber intake

Correct answer: B

Rationale: Reducing potassium intake is important for patients with chronic kidney disease to prevent hyperkalemia.

3. Larry, 55 years old, who is suspected of having colorectal cancer, is admitted to the CI. After taking the history and vital signs the physician does which test as a screening test for colorectal cancer.

• A. Barium enema
• B. Carcinoembryonic antigen
• C. Annual digital rectal examination
• D. Proctosigmoidoscopy

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.

4. What sensation is used as a gauge so that patients with ileostomy can determine how often their pouch should be drained?

• A. Sensation of taste
• B. Sensation of pressure
• C. Sensation of smell
• D. Urge to defecate

Correct answer: B

Rationale: The correct answer is B: Sensation of pressure. Patients with ileostomy can determine how often their pouch should be drained by feeling the sensation of pressure. This is important as it helps prevent leakage or overflow of the pouch. The sensation of taste (choice A) and smell (choice C) are not typically used as gauges for draining the pouch in ileostomy patients. The urge to defecate (choice D) is not relevant in this context as patients with ileostomy do not pass stool through the rectum.

5. A nurse is preparing to administer a gavage feeding via a nasogastric tube to a preterm newborn who is receiving supplemental oxygen. Which of the following actions should the nurse take?

• A. Stabilize the tube with tape to the newborn’s cheek.
• B. Remove supplemental oxygen during the feeding.
• C. Measure the stomach aspirate prior to the feeding.
• D. Place the newborn on their left side for 30 minutes after the feeding.

Correct answer: C

Rationale: Measuring the stomach aspirate prior to the feeding is crucial to ensure the correct placement and function of the nasogastric tube. This step helps prevent complications such as aspiration or improper feeding. Choice A is incorrect as stabilizing the tube with tape to the newborn’s cheek can cause discomfort and skin irritation. Choice B is incorrect because removing supplemental oxygen during the feeding may compromise the newborn's respiratory status. Choice D is incorrect because placing the newborn on their left side for 30 minutes after the feeding is not a standard practice and is unnecessary for administering gavage feeding.
