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.

• B. There is an increase blood pressure during pregnancy increasing the likelihood of hemorrhage

3. What type of drug would most likely be given to a patient following a myocardial infarction?

• A. antiemetic
• B. anticoagulant
• C. anticonvulsant
• D. antibiotic

Correct answer: B

Rationale: Anticoagulants are the most suitable choice for a patient following a myocardial infarction. These medications are essential in preventing further blood clots from forming in the arteries, reducing the risk of complications such as strokes or recurrent heart attacks. Antiemetics are used to control nausea and vomiting, not directly related to myocardial infarction. Anticonvulsants are used to manage seizures, not typically indicated after a heart attack. Antibiotics are prescribed to treat bacterial infections, not routinely given after a myocardial infarction.

4. A client is experiencing sleep disturbances and desires to decrease caffeine intake. Which of the following beverages should the nurse recommend?

• A. Lemon-lime soda
• B. Brewed iced tea
• C. Diet cola
• D. Chocolate milk

Correct answer: B

Rationale: The nurse should recommend brewed iced tea as it generally contains less caffeine compared to other choices. Lemon-lime soda, diet cola, and chocolate milk all contain caffeine, which can contribute to sleep disturbances. Lemon-lime soda and diet cola are carbonated beverages that typically contain caffeine unless specified as caffeine-free. Chocolate milk also contains caffeine due to the cocoa content. Therefore, brewed iced tea is the most suitable choice to reduce caffeine intake and improve sleep quality.

Milk (choice B) is also a common allergen but is typically introduced earlier in a child's diet. Bananas (choice C) and citrus fruits (choice D) are less likely to cause allergic reactions compared to eggs.
