A nurse is assessing a client for a positive Chvostek's sign following a thyroidectomy. Which of the following areas on the client's head should the nurse tap to assess the client for tetany?
The Correct Answer is B
To assess a client for a positive Chvostek’s sign, the nurse should tap gently on the cheek, specifically two centimeters in front of the ear, over the facial nerve (also known as CN VII). This test is used to check for hypocalcemia, a condition that can lead to tetany, which is the involuntary contraction of muscles. A twitch of the facial muscles in response to this tapping indicates a positive Chvostek’s sign. This is particularly relevant following a thyroidectomy, as the procedure can indirectly affect the parathyroid glands, potentially leading to hypocalcemia

Correct Answer is D
Explanation
A low potassium level (hypokalemia) can increase the risk for digoxin toxicity because it enhances the binding of digoxin to cardiac cells and increases its effects on cardiac contractility and electrical conduction. The nurse should monitor the client's potassium level and administer potassium supplements as prescribed if needed. The other electrolytes are not directly related to digoxin toxicity.
Correct Answer is A
Explanation
A platelet count of 95,000/mm is below the normal range of 150,000 to 400,000/mm and indicates thrombocytopenia, which increases the risk of bleeding during surgery. The nurse should report this value to the surgeon and anticipate interventions such as transfusion of platelets or postponement of surgery. The other values are within normal limits and do not require immediate attention.
