Nursing Elites

1. When performing endotracheal suctioning, the nurse applies suctioning while withdrawing and gently rotating the catheter 360 degrees for which of the following time periods?

• A. 10-15 seconds
• B. 30-35 seconds
• C. 20-25 seconds
• D. 0-5 seconds

Correct answer: D

Rationale: During endotracheal suctioning, the nurse should apply suctioning while withdrawing and gently rotating the catheter 360 degrees for a short period of 0-5 seconds. This brief duration helps minimize the risk of hypoxia and trauma to the airway. Choices A, B, and C suggest longer time periods for suctioning, which can increase the risk of complications such as hypoxia, mucosal damage, and the removal of excess amounts of airway secretions.

2. A vegan patient might be at risk for deficiency in which of the following nutrients?

• A. Vitamin B12
• B. Vitamin C
• C. Carbohydrates
• D. Fiber

Correct answer: A

Rationale: The correct answer is Vitamin B12. Vitamin B12 is primarily found in animal products, so individuals following a vegan diet are at risk of deficiency as they do not consume these sources. Vitamin C, Carbohydrates, and Fiber are not specifically at risk for deficiency in vegan diets as they can be obtained from plant-based sources.

3. Sickle cell disease is an example of an inherited mistake in the amino acid sequence.

• A. TRUE
• B. FALSE
• C.
• D.

Correct answer: A

Rationale: The statement is TRUE. Sickle cell disease is caused by a genetic mutation in the hemoglobin gene, leading to an abnormal amino acid sequence. This results in the production of abnormal hemoglobin molecules, causing red blood cells to become sickle-shaped. This inherited condition is a classic example of a genetic error affecting the amino acid sequence, making choice A the correct answer. Choices B, C, and D are incorrect as they do not accurately reflect the nature of sickle cell disease.

4. Which enzyme initiates protein digestion in the stomach?

• A. Pepsin
• B. Salivary Amylase
• C. CCK
• D. Secretin

Correct answer: A

Rationale: Pepsin is the enzyme that initiates protein digestion in the stomach. It breaks down proteins into smaller peptides, aiding in their further digestion and absorption in the intestines. Salivary Amylase (Choice B) functions in breaking down dietary carbohydrates in the mouth, not proteins. CCK (Choice C) and Secretin (Choice D) are hormones involved in the digestion of fats and carbohydrates, not proteins. Therefore, Choices B, C, and D are incorrect in the context of protein digestion in the stomach.

5. After reviewing the health and dental histories, the dental hygienist has adequate information to begin dietary counseling with the patient. Providing a standardized, low-carbohydrate menu is sufficient for most patients with a high caries rate.

• A. Both statements are true
• B. Both statements are false
• C. The first statement is true; the second is false
• D. The first statement is false; the second is true

Correct answer: B

Rationale: Both statements are false. Dietary counseling should be personalized, and a standardized low-carbohydrate menu is not sufficient for all patients.
