The nurse is providing teaching to the client about the use of vitamins and supplements. The nurse would state that vitamin D has a major role in which process?

Facilitating sodium and potassium exchange

DNA and prothrombin synthesis

Regulating calcium and phosphorus metabolism

Production of beta carotene

Answer and Explanation

The Correct Answer is C

A. Facilitating sodium and potassium exchange: This is not related to vitamin D. Sodium and potassium exchange is primarily managed by other mechanisms in the body.
B. DNA and prothrombin synthesis: This role is more associated with vitamins like B12 and K, not vitamin D.
C. Regulating calcium and phosphorus metabolism: This is the correct choice. Vitamin D plays a crucial role in the absorption of calcium and phosphorus from the diet and their metabolism in the body.
D. Production of beta carotene: Beta carotene is a precursor to vitamin A, not related to vitamin D's functions.

Correct Answer is A

Explanation

A. Steak and scrambled eggs: Steak and scrambled eggs are excellent sources of heme iron, which is highly bioavailable and easily absorbed by the body. This choice reflects a good understanding of dietary sources rich in iron.
B. Cornmeal muffin and orange juice: While orange juice can enhance iron absorption due to its vitamin C content, cornmeal muffins are not a significant source of iron. This option does not indicate a strong understanding of iron-rich foods.
C. Cantaloupe and cottage cheese: Both cantaloupe and cottage cheese are low in iron content. This menu choice does not reflect an understanding of the best dietary sources of iron.
D. Strawberry pancakes and coffee: Strawberries have some iron, but not in significant amounts, and coffee can inhibit iron absorption due to its polyphenol content. This choice does not indicate an understanding of iron-rich foods.

A. Capillary refill and depth of peripheral edema B. Abdominal sounds and obtain a BNP level C. Neurological status and obtain electrolyte levels D. Skin turgor and measure intake & output (I&O)

Correct Answer is C

Explanation

A. Capillary refill and depth of peripheral edema: While these assessments are important for evaluating peripheral circulation and fluid status, they are not as immediately critical given the client's new onset of confusion and respiratory symptoms.
B. Abdominal sounds and obtain a BNP level: Assessing abdominal sounds and BNP (B-type natriuretic peptide) levels is useful for diagnosing heart failure exacerbations but is secondary to addressing the client's acute confusion and potential electrolyte imbalances.
C. Neurological status and obtain electrolyte levels: This is the correct choice. New onset confusion can be indicative of electrolyte imbalances or acute exacerbations related to heart failure. Monitoring neurological status and electrolyte levels is crucial to address potential causes of confusion and ensure proper treatment.
D. Skin turgor and measure intake & output (I&O): While skin turgor and I&O are relevant for assessing fluid status, the priority should be addressing the acute change in mental status and potential underlying causes such as electrolyte imbalances.
