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. What goal should an overweight woman include in her lifestyle for a healthy pregnancy?

• A. Aim to lose 11 to 20 pounds during pregnancy
• B. Increase protein intake to 35% of total calories
• C. Delay weight loss until after pregnancy
• D. Increase daily energy intake by 550 calories

Correct answer: C

Rationale: The healthiest approach for an overweight pregnant woman is to delay weight loss until after pregnancy. During pregnancy, the body needs sufficient nutrition and energy to support the growth and development of the baby. Attempting to lose weight during pregnancy, especially significant amounts, may compromise the health of both the mother and the baby. Increasing protein intake to 35% of total calories or energy intake by 550 calories per day without professional guidance may lead to an unbalanced diet, which is not optimal for pregnancy. The focus should be on maintaining a balanced, nutrient-rich diet and appropriate weight gain during pregnancy.

3. Is it correct that eliminating sucrose from the diet leads to a significant reduction in dental caries, and that the best advice is to consume sugar in moderation and limit the frequency of sugar exposure?

• 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: D

Rationale: The first statement is incorrect because dental caries are not solely caused by sucrose. They are the result of a complex interaction of multiple factors, including the type of bacteria in the mouth, the host's diet, oral hygiene, and salivary flow. The second statement is correct as consuming sugar in moderation and limiting the frequency of sugar exposure are indeed effective strategies to prevent dental caries. Therefore, the answer is option D: The first statement is false; the second is true.

4. Churns chyme and has an environment of pH2; holds 4-6 cups of food:

• A. stomach
• B. pancreas
• C. large intestine
• D. small intestine

Correct answer: A

Rationale: The stomach churns food into chyme and has a highly acidic environment (pH 2) to aid in the digestion of proteins and other nutrients.

5. Starting material for sex hormones:

• A. cholesterol
• B. phospholipid
• C. saturated
• D. triglyceride
