1. 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.

2. Which is most likely to initiate periodontal disease?

• A. Nutrient deficiencies
• B. Nutrient excesses
• C. Nutrient imbalances
• D. Plaque biofilm

Correct answer: D

Rationale: Plaque biofilm is the primary initiator of periodontal disease, as it harbors bacteria that can lead to inflammation and destruction of the periodontal tissues.

3. Studies suggest that leukoplakia is resolved by excess vitamin A (a fat-soluble vitamin), retinoids, and beta-carotene. Leukoplakia is a white plaque that forms on oral mucous membranes.

• 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. Studies suggest that leukoplakia, a white plaque that forms on oral mucous membranes, can be resolved by vitamin A, retinoids, and beta-carotene. Despite the potential to resolve leukoplakia, relapse is common. Also pertinent, evidence does not indicate that any of these nutrients prevent malignant transformation. The extract provided clarifies that leukoplakia is a white plaque, not an erythematous lesion, and that vitamin A, retinoids, and beta-carotene can help resolve it.

4. She instructed the interviewees not to tell the interviewees that the data gathered are for her own research project for publication. This teacher has violated the student’s right to:

• A. Not be harmed
• B. Disclosure
• C. Privacy
• D. Self-determination

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. What is the most common type of kidney stone?

• A. Cystine
• B. Calcium
• C. Struvite
• D. Uric acid

Correct answer: B

Rationale: The most common type of kidney stone is calcium-based, specifically calcium oxalate. This is usually due to high calcium levels in the urine, which can be caused by dietary factors or certain metabolic disorders. Cystine stones, on the other hand, are less common and occur in individuals with a hereditary disorder leading to excessive excretion of certain amino acids. Struvite stones are often formed in response to an infection. Uric acid stones may occur in individuals who do not consume sufficient fluids or who lose too much fluid, among other factors. Therefore, while all these substances can form stones in the kidneys, calcium stones are the most common.
