Patients who have hypocalcemia will exhibit laryngeal spasms, numbness of fingers, and twitching of the mouth. The other symptoms are not characteristic of hypocalcemia.
Answer to Question 2
ANS: C
Fluid maintenance needs for the NPO patient are calculated as 4 mL/kg/h for the first 10 kg of weight, 2 mL/kg/h for the second 10 kg of weight, and 1 mL/kg/h for every kg of weight thereafter. This patient's fluid needs are (10 kg 4 mL) + (10 kg 2 mL) + (45 kg 1 mL) = 105 mL/h. The 24-hour total is 105 mL/h 24 h = 2,520 mL.
