Question 1 of 5
A nurse is reinforcing teaching with the parents of a school-age child who has cystic fibrosis. Which of the following statements should the nurse make?
Correct Answer: C
Rationale: Daily aerobic exercise promotes lung function and airway clearance in children with cystic fibrosis.
Question 2 of 5
A nurse is collecting data from a client who has a calcium level of 8 mg/dL (9.0-10.5 mg/dL). Which of the following manifestations should the nurse expect?
Correct Answer: D
Rationale: Tetany, involving muscle cramps and spasms, is a common manifestation of hypocalcemia due to increased neuromuscular excitability at low calcium levels.
Question 3 of 5
The nurse is reviewing laboratory results for a group of patients. Which value should be of most concern to the nurse?
Correct Answer: B
Rationale: A magnesium level of 1.0 mEq/L indicates hypomagnesemia, which can cause serious complications like arrhythmias and seizures, making it the most concerning value.
Question 4 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 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.
