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. Which of the following are the primary bacteria involved in the initiation of dental caries?

• A. Streptococcus mutans and Lactobacillus species
• B. Salmonella and Listeria species
• C. Streptococcus, Lactobacillus, and Salmonella species
• D. Listeria, Botulinum species, and Escherichia coli

Correct answer: A

Rationale: The correct answer is A: Streptococcus mutans and Lactobacillus species. These bacteria are primarily responsible for initiating dental caries by fermenting carbohydrates and producing acids that demineralize enamel. Choice B, Salmonella and Listeria species, are not the primary bacteria involved in dental caries. Choice C includes Salmonella which is not a primary culprit in dental caries. Choice D lists Listeria, Botulinum species, and Escherichia coli, none of which are the primary bacteria associated with initiating dental caries.

3. What food assistance program provides a food debit card for older adults with low incomes?

• A. the OAA Nutrition Program
• B. Meals on Wheels
• C. the Supplemental Nutrition Assistance Program
• D. the Emergency Food Assistance Program

Correct answer: C

Rationale: The correct answer is C: the Supplemental Nutrition Assistance Program (SNAP). SNAP provides a food debit card to assist low-income individuals, including older adults, in purchasing food. Choice A, the OAA Nutrition Program, is incorrect as it refers to a different program specifically focused on providing nutrition services to older adults. Choice B, Meals on Wheels, is incorrect as it is a meal delivery service for homebound individuals rather than a food debit card program. Choice D, the Emergency Food Assistance Program, is incorrect as it typically involves the distribution of emergency food supplies rather than providing a food debit card.

4. What sensation is used as a gauge so that patients with ileostomy can determine how often their pouch should be drained?

• A. Sensation of taste
• B. Sensation of pressure
• C. Sensation of smell
• D. Urge to defecate

Correct answer: B

Rationale: The correct answer is B: Sensation of pressure. Patients with ileostomy can determine how often their pouch should be drained by feeling the sensation of pressure. This is important as it helps prevent leakage or overflow of the pouch. The sensation of taste (choice A) and smell (choice C) are not typically used as gauges for draining the pouch in ileostomy patients. The urge to defecate (choice D) is not relevant in this context as patients with ileostomy do not pass stool through the rectum.

5. A nurse is providing teaching to a group of parents of newborns who are planning to formula feed. Which of the following statements by a parent indicates a need for further teaching?

• A. "I will give formula to my baby at room temperature."
• B. "I will ensure my baby's feeds last 10 to 15 minutes."
• C. "I will burp my baby halfway through each feeding."
• D. "I will watch for signs my baby is full and stop the feeding."

Correct answer: B

Rationale: The correct answer is, "I will ensure my baby's feeds last 10 to 15 minutes." This statement indicates a need for further teaching because it suggests a strict time limit for feedings, which may not be appropriate for a newborn. Newborns should be allowed to feed as long as they want, typically around 20-30 minutes per breast if breastfeeding, or on-demand with formula. Choices A, C, and D demonstrate proper feeding practices such as feeding at room temperature, burping halfway through each feeding, and watching for signs of fullness to stop the feeding, which are all appropriate responses by a parent of a formula-fed newborn.
