1. The major determinant of a person's total cholesterol levels is the amount of cholesterol in their diet.

• A. True
• B. False
• C.
• D.

Correct answer: B

Rationale: It is false that the major determinant of a person's total cholesterol levels is the amount of cholesterol in their diet. While dietary cholesterol can have some impact on total cholesterol levels, it is not the major determinant. The amount and types of fats consumed, particularly saturated and trans fats, have a more significant impact on blood cholesterol levels. Therefore, a diet high in these types of fats can lead to high cholesterol, irrespective of the amount of dietary cholesterol consumed. This is why it is essential to maintain a balanced diet with a limited intake of saturated and trans fats.

2. Cariogenic foods and beverages, which are fermentable carbohydrates that can be metabolized by oral bacteria, reduce salivary pH to what critical level?

• A. 5
• B. 5.5
• C. 6
• D. 6.5

Correct answer: B

Rationale: Cariogenic foods and beverages lower the pH level in the mouth to below 5.5. This is a critical threshold, as it is the point at which enamel begins to demineralize, increasing the risk of dental caries. Therefore, options 'A', 'C', and 'D' are incorrect. Although a pH level of 5, as suggested by option 'A', would indeed lead to demineralization, it's not the threshold value. The pH levels suggested by options 'C' and 'D' (6 and 6.5, respectively) are higher than the critical value of 5.5, which means they would not initiate enamel demineralization and the subsequent risk of dental caries.

3. A client has a small-bore jejunostomy and is receiving a continuous tube feeding with a high-viscosity formula. Which of the following actions should the nurse take to prevent the tubing from clogging?

• A. Replace the bag and tubing every 24 hours
• B. Flush the tubing with 10 mL water every 6 hours
• C. Administer the feeding by gravity drip
• D. Heat the formula prior to infusion

Correct answer: B

Rationale: To prevent clogging when using high-viscosity formulas in a small-bore jejunostomy, the nurse should flush the tubing with 10 mL of water every 6 hours. This action helps maintain tube patency and prevent blockages. Replacing the bag and tubing every 24 hours (Choice A) is unnecessary and does not specifically address preventing clogging. Administering the feeding by gravity drip (Choice C) or heating the formula prior to infusion (Choice D) are not effective interventions for preventing tubing clogging.

4. Which of the following nursing interventions is appropriate after a total thyroidectomy?

• A. Place pillows under your patient’s shoulders.
• B. Raise the knee-gatch to 30 degrees
• C. Keep you patient in a high-fowler’s position.
• D. Support the patient’s head and neck with pillows and sandbags.

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.

5. After ileostomy, which of the following condition is NOT expected?

• A. Increased weight
• B. Irritation of skin around the stoma
• C. Liquid stool
• D. Establishment of regular bowel movement

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.
