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 D

Explanation

A. A 47-year-old client who reports two loose stools with a serum sodium of 139 mmol/L: Although diarrhea can lead to electrolyte imbalances, a serum sodium level of 139 mmol/L is within normal range, so this client is not the highest priority.
B. A 71-year-old client with a calcium level of 8.9 mg/dL and a negative Trousseau sign: A calcium level of 8.9 mg/dL is slightly low but not critically low, especially with a negative Trousseau sign. This client is stable compared to others.
C. A 52-year-old client with fluid volume excess and BUN of 18 mg/dL: A BUN of 18 mg/dL indicates mild elevation, and fluid volume excess can be managed with adjustments in treatment; this client does not require immediate priority.
D. A 60-year-old client with a serum potassium of 3.2 mEq/L and heart palpitations: A potassium level of 3.2 mEq/L indicates hypokalemia, which can cause serious cardiac issues and symptoms like palpitations. This client requires urgent attention to address the potential risk of cardiac complications.

A. Blood in the tubing close to the insertion site B. Chills, fever, and generalized discomfort C. Pallor, sweating, and discomfort at the insertion site D. Dyspnea, headache, and increased blood pressure

Correct Answer is D

Explanation

A. Blood in the tubing close to the insertion site: This indicates a possible issue with the IV but not fluid overload specifically.
B. Chills, fever, and generalized discomfort: These symptoms may suggest an infection or reaction but are not specific to fluid overload.
C. Pallor, sweating, and discomfort at the insertion site: These could indicate a local reaction or issue with the IV site but not fluid overload.
D. Dyspnea, headache, and increased blood pressure: These symptoms are indicative of fluid overload, as the body reacts to excessive fluid with symptoms such as difficulty breathing (dyspnea), increased blood pressure, and headaches.
