Nursing Elites

1. You will do nasopharyngeal suctioning on Mr. Abad. Your guide for the length of insertion of the tubing for an adult would be:

• A. tip of the nose to the base of the neck
• B. the distance from the tip of the nose to the middle of the neck
• C. the distance from the tip of the nose to the tip of the ear lobe
• D. eight to ten inches

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.

2. For patients with anemia, which vitamin is crucial for the absorption of iron?

• A. Vitamin A
• B. Vitamin C
• C. Vitamin D
• D. Vitamin E

Correct answer: B

Rationale: The correct answer is Vitamin C. Vitamin C enhances the absorption of non-heme iron, which is crucial for patients with anemia. Vitamin A (Choice A) is not directly involved in iron absorption. Vitamin D (Choice C) helps with calcium absorption, not iron. Vitamin E (Choice D) does not have a significant role in iron absorption.

3. Children with cerebral palsy, Down syndrome, and intellectual disabilities are likely to have abnormal sensory input and muscle tone. A small, underdeveloped tongue is common in many such disorders and results in diminished nutritional status.

• 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: C

Rationale: The first statement is true, but the second is false. These children often have a large tongue or tongue thrust, which can interfere with feeding and nutrition.

4. Each statement is true regarding oral exposure to fermentable carbohydrates, except one. Which is the exception?

• A. Longer exposure leads to an increased risk of demineralization
• B. Longer exposure increases the opportunity for remineralization
• C. The Stephan curve illustrates pH changes within plaque after rinsing with a sugar solution
• D. The critical pH at which enamel decalcification occurs is 5.5 or less

Correct answer: B

Rationale: All the statements above are accurate about oral exposure to fermentable carbohydrates, except for option B. In fact, longer exposure to these carbohydrates decreases the opportunity for remineralization. This is because the process of demineralization, in which minerals are lost from the tooth enamel, is sped up by the presence of fermentable carbohydrates. The Stephan curve (option C) is a graph that demonstrates how the pH of dental plaque changes after a sugar rinse, usually dropping (becoming more acidic), which can lead to enamel decalcification. Option D is also accurate, as a pH of 5.5 or lower is the critical point at which enamel starts to decalcify.

5. All of the following are electrolytes except:

• A. chloride
• B. potassium
• C. sodium
• D. iron

Correct answer: D

Rationale: Iron is not an electrolyte; electrolytes like sodium, potassium, and chloride help maintain fluid balance and are critical for nerve and muscle function.
