Extract:
Question 1 of 5
A nurse is assisting with the care of a client who has hypocalcemia. For which of the following signs should the nurse monitor?
Correct Answer: B
Rationale: Chvostek's sign, facial muscle twitching when the facial nerve is tapped, is a classic indicator of hypocalcemia.
Question 2 of 5
A nurse is assisting with care of a client who has a prescription for 3,000 mL of intravenous fluids over the next 24 hr. The nurse should set the IV pump to deliver how many mL/hr? (Round to the nearest whole number)
Correct Answer: B
Rationale: Dividing total volume by time, 3000 mL / 24 hr = 125 mL/hr.
Question 3 of 5
A nurse is planning to monitor a client for dehydration following several episodes of vomiting and an increase in the client's temperature. Which of the following findings should the nurse identify as an indication that the client is dehydrated?
Correct Answer: A
Rationale: High urine specific gravity (1.034) indicates concentrated urine, a sign of dehydration as the kidneys conserve water.
Question 4 of 5
A nurse is collecting data from a client who has a calcium level of 12 mg/dL (9-10.5 mg/dL). Which of the following manifestations should the nurse expect?
Correct Answer: B
Rationale: Hypercalcemia depresses neuromuscular function, leading to decreased deep tendon reflexes.
Question 5 of 5
A nurse is preparing to administer 400 mL of 0.9% sodium chloride IV over 8 hr. The drop factor of the manual IV tubing is 60 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: B
Rationale: Using the formula Flow rate (gtt/min) = (Volume/Time) × Drop factor, 400 mL / (8 × 60) × 60 gtt/mL = 50 gtt/min.
