Nursing Elites

1. What is tocopherol?

• A. Vitamin B1
• B. Vitamin B2
• C. Vitamin B3
• D. Vitamin E

Correct answer: D

Rationale: Tocopherol is another name for Vitamin E, a fat-soluble antioxidant that helps protect cell membranes from oxidative damage. Choices A, B, and C are incorrect as tocopherol is specifically related to Vitamin E and not Vitamin B1, B2, or B3.

2. Dina, 17 years old, asks you how a tubal ligation prevents pregnancy. Which would be the best answer?

• A. Prostaglandins released from the cut fallopian tubes can kill sperm
• B. Sperm cannot enter the uterus because the cervical entrance is blocked
• C. Sperm can no longer reach the ova, because the fallopian tubes are blocked
• D. The ovary no longer releases ova as there is nowhere for them to go

Correct answer: C

Rationale: The correct answer is C: 'Sperm can no longer reach the ova because the fallopian tubes are blocked.' Tubal ligation works by blocking the fallopian tubes, preventing sperm from reaching the egg for fertilization. Choice A is incorrect because prostaglandins are not released from the cut fallopian tubes to kill sperm. Choice B is incorrect as the cervical entrance being blocked does not relate to tubal ligation. Choice D is incorrect because tubal ligation does not affect the release of ova from the ovary.

3. A dental hygienist finds several new carious lesions in a patient with chronic obstructive respiratory disease (COPD). While conducting the medical and dental histories, the dental hygienist is most likely to find an increased use of which of the following?

• A. Protein
• B. Cough drops
• C. Fluoride
• D. Xylitol

Correct answer: B

Rationale: The correct answer is B: Cough drops. Patients with COPD often use cough drops to manage their symptoms, which can lead to an increase in carious lesions due to their sugar content. Choices A, C, and D are incorrect as protein, fluoride, and xylitol are not typically associated with an increased risk of carious lesions in patients with COPD.

4. A nurse is instructing a group of clients about nutrition and eating foods high in iron. The nurse should include that which of the following aids in the absorption of iron?

• A. Fiber
• B. Vitamin A
• C. Vitamin C
• D. Oxalates

Correct answer: C

Rationale: Vitamin C aids in the absorption of iron by enhancing the body's ability to absorb non-heme iron, which is found in plant-based foods. This vitamin helps convert iron into a form that is more easily absorbed in the intestines. Choices A, B, and D are incorrect because fiber, Vitamin A, and oxalates can actually inhibit the absorption of iron. Fiber can bind to iron and reduce its absorption, Vitamin A does not directly enhance iron absorption, and oxalates found in some foods like spinach and rhubarb can also hinder iron absorption.

5. Loss of smell results in a condition that limits the capacity to detect the flavor of food and beverages, called:

• A. hypergeusia
• B. dysgeusia
• C. anosmia
• D. phantom taste

Correct answer: C

Rationale: The correct answer is C: anosmia. Anosmia refers to the loss of smell, which significantly affects the ability to detect flavors. Hypergeusia and dysgeusia, choices A and B, refer to heightened or distorted taste, respectively. 'Phantom taste' in choice D is not the correct term for the condition described in the question.
