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. Each of the following is a fat-soluble vitamin except for one. Which is the exception?

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

Correct answer: B

Rationale: The correct answer is B, Vitamin C. Vitamin C is a water-soluble vitamin, not fat-soluble. Fat-soluble vitamins are Vitamins A, D, E, and K. These vitamins are stored in the body's fat tissues and liver, unlike water-soluble vitamins which are not stored and are eliminated in urine, making them less likely to reach toxic levels.

3. A nurse is caring for a client who is lactose intolerant. Which of the following clinical manifestations should the nurse assess?

• A. Fever
• B. Blood in stools
• C. Cramping
• D. Steatorrhea

Correct answer: C

Rationale: The correct answer is C: Cramping. Cramping is a common clinical manifestation of lactose intolerance due to the inability to digest lactose properly. Fever (choice A) is not typically associated with lactose intolerance. Blood in stools (choice B) is more indicative of other gastrointestinal issues like inflammatory bowel disease. Steatorrhea (choice D) is the presence of excess fat in the stool and is not a typical symptom of lactose intolerance.

4. AIDS enteropathy is most commonly manifested as _____.

• A. abdominal pain and rectal bleeding
• B. diarrhea and weight loss
• C. abdominal bloating and flatulence
• D. rectal fissures and constipation

Correct answer: B

Rationale: AIDS enteropathy typically presents as diarrhea and weight loss due to the impact of HIV on the gastrointestinal tract. While abdominal pain and rectal bleeding (Choice A), abdominal bloating and flatulence (Choice C), and rectal fissures and constipation (Choice D) can occur in some cases, the most common manifestations are diarrhea and weight loss.

5. What principle is used when the client with fever loses heat through giving cooling bed bath to lower body temperature?

• A. Radiation C. Evaporation
• B. Convection D. Conduction
• C.
• D.

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.
