A nurse reviews a client's laboratory report and notes that the client's serum phosphorus (phosphate) level is 1.8 mg/dL. Which condition most likely caused this serum phosphorus level?

Hypercholesterolemia

Malnutrition

Renal insufficiency

Hypoparathyroidism

Answer and Explanation

The Correct Answer is B

A. Hypercholesterolemia: This condition primarily affects cholesterol levels and is not directly associated with phosphorus imbalances. It does not typically cause hypophosphatemia.
B. Malnutrition: This is the correct choice. Malnutrition can lead to hypophosphatemia (low serum phosphorus levels) due to inadequate dietary intake of phosphorus and impaired absorption.
C. Renal insufficiency: Renal insufficiency generally causes hyperphosphatemia (high serum phosphorus levels) due to the kidneys' reduced ability to excrete phosphate, not hypophosphatemia.
D. Hypoparathyroidism: This condition is more commonly associated with hypocalcemia (low calcium levels) rather than hypophosphatemia. In some cases, hypoparathyroidism can cause elevated phosphorus levels, but not typically hypophosphatemia.

Correct Answer is D

Explanation

A. Dry oral mucus membranes: This finding indicates dehydration rather than improvement. Effective treatment would result in the rehydration of mucous membranes.
B. Weight loss: Weight loss can be a sign of ongoing dehydration or fluid loss. Effective treatment would be indicated by weight stabilization or gain, not loss.
C. Jugular vein distention: Jugular vein distention typically indicates fluid overload or poor cardiac function, not improvement in dehydration. Effective rehydration would be associated with a return to normal vein appearance.
D. Daily urine output of 960 mL: This is the correct choice as it reflects adequate fluid intake and kidney function. For an average adult, a daily urine output of around 960 mL suggests proper hydration, indicating that interventions have been effective.

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.
