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. Low levels of high-density lipoproteins (HDL) are?

• A. associated with being underweight
• B. more prevalent in males
• C. highly predictive of CHD risk
• D. not a good predictor of CHD risk

Correct answer: C

Rationale: Low levels of HDL cholesterol are a strong predictor of coronary heart disease (CHD) risk because HDL helps to remove excess cholesterol from the bloodstream. Choice A is incorrect because low HDL levels are not associated with being underweight but rather with increased CHD risk. Choice B is incorrect as low HDL levels are not more prevalent in males but can affect both genders. Choice D is incorrect as low levels of HDL are indeed a good predictor of CHD risk.

3. Tony is to be discharged in the afternoon of the same day after tonsillectomy and adenoidectomy. You, as the RN, will make sure that the family knows to:

• A. offer pureed foods
• B. offer soft foods for a week to minimize discomfort while swallowing
• C. supplement his diet with Vitamin C-rich foods to enhance healing
• D. offer clear liquids for 3 days to prevent irritation

Correct answer: B

Rationale: After tonsillectomy and adenoidectomy, it is crucial to provide soft foods for a week to minimize discomfort while swallowing. This helps prevent irritation to the surgical site and allows for easier healing. Offering pureed foods (Choice A) may not be necessary as soft foods are usually sufficient. While Vitamin C is beneficial for healing, it is not necessary to supplement it immediately after surgery with Vitamin C-rich juices (Choice C). Clear liquids are typically recommended before surgery and not after, as the focus shifts to soft foods to aid in recovery, making Choice D incorrect.

4. Dental hygienists are in a key position to assess and detect signs and symptoms of systemic disease because more than one third of the patients treated in a dental office frequently do not interact with a general health care provider.

• A. Both the statement and the reason are correct and related
• B. Both the statement and the reason are correct but are not related
• C. The statement is correct, but the reason is not correct
• D. The statement is not correct, but the reason is correct

Correct answer: A

Rationale: Dental hygienists often see patients more regularly than general healthcare providers, allowing them to identify systemic issues early.

5. In conducting a cleansing enema, how does the nurse position the client?

• A. Right lateral position
• B. Left lateral position
• C. Right Sim's position
• D. Left Sim's position

Correct answer: B

Rationale: In preparing a patient for a cleansing enema, the nurse typically positions the patient in the left lateral position. This position allows for the best flow of the solution due to the anatomical configuration of the colon. The right lateral position, right Sim's position, and left Sim's position are not typically used for this procedure. The rationale provided initially is incorrect as it pertains to lung expansion and postural drainage, which are not relevant to a cleansing enema procedure.
