1. Each statement regarding the correlation between vitamin D and sun exposure is accurate, except one. Which is the exception?

• A. The body can produce sufficient amounts of vitamin D from sunlight.
• B. UV radiation can convert a precursor of vitamin D to vitamin D3 by penetrating uncovered skin.
• C. Sunscreen blocks the formation of vitamin D3.
• D. By the age of 70 years, the skin generally produces vitamin D at only half the level it did at the age of 20 years.

Correct answer: C

Rationale: While UV radiation can penetrate uncovered skin and convert a precursor of vitamin D to vitamin D3, sunscreen does block the formation of vitamin D3. Sunscreen is recommended by dermatologists to prevent sunburn and reduce the risk of skin cancer. The other choices are correct: the body can produce sufficient vitamin D from sunlight, UV radiation can convert a precursor of vitamin D to vitamin D3, and skin generally produces less vitamin D as a person ages.

2. Bacterial growth and plaque formation are enhanced by a diet with frequent intake of retentive carbohydrates. Gingivitis is an irreversible change in the interdental papillary tissues.

• 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 correct answer is C. The first statement is true; retentive carbohydrates promote bacterial growth and plaque formation. However, the second statement is false; gingivitis is not irreversible and is often reversible with proper care. Gingivitis is the inflammation of the gums due to plaque buildup and poor oral hygiene. With good oral hygiene practices and professional dental care, gingivitis can be reversed. The other choices are incorrect because gingivitis is not irreversible, making statement two false.

3. The rationales for using a prostaglandin gel for a client prior to the induction of labor is to:

• A. Soften and efface the cervix
• B. Numb cervical pain receptors
• C. Prevent cervical lacerations
• D. Stimulate uterine contractions

• 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

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.

• A. X-ray
• B. Observation of gastric aspirate
• C. Testing of pH of gastric aspirate
