Question 1 of 5
Which assessment finding will the nurse expect for a patient with the following laboratory values: sodium 145 mEq/L, potassium 45 mq, calcium 45 mg/dL?
Correct Answer: D
Rationale:
Correct
Answer: D - Tingling of extremities
Rationale:
1. Hyperkalemia (high potassium) causes tingling sensations in extremities due to nerve conduction abnormalities.
2. Hyponatremia (high sodium) and hypocalcemia (low calcium) do not typically cause tingling sensations.
3. Light-headedness when standing up is associated with orthostatic hypotension, not these lab values.
4. Weak quadriceps muscles and decreased deep tendon reflexes are not typical manifestations of these lab abnormalities.
Summary:
The correct answer is D because hyperkalemia can cause nerve conduction abnormalities leading to tingling sensations in extremities. Light-headedness, weak muscles, and decreased reflexes are not associated with these specific lab values.
