1. Which enzyme digests fiber in the large intestine?

• A. salivary amylase
• B. pancreatic amylase
• C. cellulase
• D. none of the above

Correct answer: D

Rationale: The correct answer is 'none of the above.' Human digestive enzymes like salivary amylase and pancreatic amylase cannot digest fiber. Instead, fiber is fermented by gut bacteria in the large intestine. Cellulase, which is an enzyme produced by some animals and microorganisms, can break down cellulose found in plants, but it is not a human digestive enzyme, making it an incorrect choice in this context.

2. Which of the following statements are correct?

• A. Lipids are transported in the blood as lipoproteins, which are clusters of lipids associated with proteins.
• B. In type II diabetes, the pancreas produces insulin, but cells are resistant to this signal.
• C. The glycemic index classifies foods based on their potential to raise blood glucose levels.
• D. All of the above

Correct answer: D

Rationale: Option A is correct because lipoproteins indeed transport lipids in the blood. They are complexes of lipids and proteins that transport water-insoluble lipids through the blood. Option B is correct as it accurately describes the condition of type II diabetes where the pancreas can produce insulin, but the cells are resistant to its signal, causing an ineffective regulation of blood sugar. Option C is also correct because the glycemic index is indeed a classification system for foods based on their potential to raise blood glucose levels. High glycemic index foods raise blood glucose levels faster than low glycemic index foods. Hence, all the statements are correct, making option D the correct answer.

3. Individuals who use antiretroviral drugs frequently develop insulin resistance and _____.

• A. hypertension
• B. hypothyroidism
• C. hyperlipidemia
• D. fluid retention

Correct answer: C

Rationale: The correct answer is C: hyperlipidemia. Antiretroviral drugs can often lead to elevated lipid levels (hyperlipidemia), which is a common side effect of this therapy. This increase in lipids can contribute to cardiovascular risk. Hypertension (choice A) is not typically associated with antiretroviral drug use. Hypothyroidism (choice B) and fluid retention (choice D) are also not commonly linked to antiretroviral therapy.

4. Which type of bath would you recommend for a patient experiencing pruritus?

• A. Saline
• B. Colloidal (oatmeal)
• C. Water
• D. Sodium bicarbonate

Correct answer: B

Rationale: The best choice for a pruritus (itching) patient is a colloidal (oatmeal) bath, as it is known for its soothing effect on itchy, irritated skin. Saline, water, and sodium bicarbonate baths may not provide the same level of relief for pruritus. The nursing care should involve comprehensive assessments and appropriate interventions to optimize patient outcomes. In this case, a colloidal bath is the most suitable intervention for a patient experiencing pruritus.

5. In kidney disease, which mineral should a patient limit intake of?

• A. Calcium
• B. Magnesium
• C. Phosphorus
• D. Potassium

Correct answer: C

Rationale: In kidney disease, patients are advised to limit the intake of phosphorus. High levels of phosphorus can be problematic as the kidneys may not be able to effectively filter it out, leading to bone health issues. Calcium (Choice A) is important for bone health, but its restriction is not typically necessary in kidney disease. Magnesium (Choice B) and potassium (Choice D) restrictions may be required in certain cases of kidney disease, but phosphorus is the mineral most commonly limited due to its impact on bone health.
