Question 1 of 5
A nurse is collecting data from a client who has hypocalcemia. Which of the following findings should the nurse expect?
Correct Answer: C
Rationale: Tingling of the lips is a classic sign of hypocalcemia, resulting from increased neuromuscular excitability causing paresthesia.
Question 2 of 5
At 0330, a nurse is caring for a client who is postoperative. The client's IV fluids are infusing at 120 mL/hr. How many mL of IV fluid should infuse by 0600? (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: From 0330 to 0600 is 2.5 hours; 120 mL/hr × 2.5 hr = 300 mL.
Question 3 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.
Question 4 of 5
A nurse is reviewing the laboratory values for a client who takes spironolactone and notes that the client's serum potassium level is 6.8 mEq/L (3.5 -5 mEq/L). The nurse notifies the provider and anticipates that the provider will provide which of the following instructions?
Correct Answer: C
Rationale: Hyperkalemia can cause life-threatening cardiac dysrhythmias, necessitating an ECG to monitor for abnormalities.
Question 5 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.
