The illustration reflects a client's upper extremity while the nurse obtains a manual blood pressure. Which electrolyte abnormality is the nurse most likely to see in the client's blood chemistry results?
Hypocalcemia
Hypokalemia
Hypophosphatemia
Hyponatremia
The Correct Answer is A
A. Hypocalcemia: Hypocalcemia can cause signs such as muscle twitching, spasms, or tetany, which could be observed in the upper extremity and might be noted during a blood pressure measurement.
B. Hypokalemia: While hypokalemia can cause muscle weakness and cramping, it is less directly associated with specific upper extremity signs compared to hypocalcemia.
C. Hypophosphatemia: This generally affects energy levels and muscle function but is less commonly associated with immediate and visible upper extremity signs.
D. Hyponatremia: This primarily affects fluid balance and mental status, and is less likely to present with specific upper extremity findings during a blood pressure check.

Correct Answer is ["A","C","D"]
Explanation
A. Record intake and output: This task is within the UAP's scope of practice as it involves documenting fluid balance.
B. Assess bowel sounds: This task requires clinical judgment and assessment skills and should be performed by a licensed nurse.
C. Obtain routine vital signs: This is appropriate for the UAP to perform, as it involves routine measurements that do not require clinical assessment.
D. Document the presence of edema: The UAP can document observable findings such as edema, which is within their scope of practice.
Correct Answer is B
Explanation
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.
