The nurse is preparing to care for a client with an electrolyte imbalance. After reviewing the electronic health record, what finding should the nurse understand places that client at the greatest risk for developing a potassium deficit?

Client's serum pH is 7.41

Client has a stage 2 sacral wound

Client requires continuous nasogastric suction

Client has a history of adrenal insufficiency

Answer and Explanation

The Correct Answer is C

A. Client's serum pH is 7.41: This is within the normal range for blood pH (7.35-7.45) and does not specifically indicate a potassium deficit.
B. Client has a stage 2 sacral wound: This is related to skin integrity and does not directly impact potassium levels.
C. Client requires continuous nasogastric suction: Continuous nasogastric suction can lead to the loss of potassium as it removes gastric contents, which may include electrolytes.
D. Client has a history of adrenal insufficiency: While adrenal insufficiency can affect electrolyte balance, continuous nasogastric suction is a more immediate risk for potassium deficit.

Correct Answer is C

Explanation

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.

A. The 22-year-old client who does not understand English B. The 17-year-old client who has two fractured wrists C. The 65-year-old client who cannot read or write D. The 80-year-old client who is not oriented to the day

Correct Answer is D

Explanation

A. The 22-year-old client who does not understand English: This client can still consent legally if provided with a translator or interpreter to ensure understanding.
B. The 17-year-old client who has two fractured wrists: This client is a minor and would typically need a legal guardian to consent, but their ability to consent is not the primary issue here.
C. The 65-year-old client who cannot read or write: Literacy issues do not necessarily preclude the ability to understand and consent, especially if the consent process is explained to them.
D. The 80-year-old client who is not oriented to the day: This client lacks orientation and thus may not be able to fully understand or make an informed decision about the surgery, affecting their ability to consent legally.
