Question 1 of 5
A nurse is assisting with the care of a school-age child who has respiratory failure due to pneumonia. Which of the following positions should the nurse encourage to allow maximal lung expansion?
Correct Answer: A
Rationale: The upright position promotes optimal lung expansion by reducing diaphragm pressure and improving ventilation.
Question 2 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 3 of 5
A nurse is preparing to administer lactated Ringer's solution IV to infuse at 120 mL/hr for a client who has a respiratory disorder. The drop factor on the manual IV tubing is 60 gtt/mL. The nurse should set the IV flow rate to deliver how many gtt/min?(Round to the nearest whole number.)
Correct Answer: A
Rationale: Using the formula Flow rate (gtt/min) = (Volume/Time) × Drop factor, 120 mL/60 min × 60 gtt/mL = 120 gtt/min.
Question 4 of 5
A nurse is assisting with the care of a school-age child who has respiratory failure due to pneumonia. Which of the following positions should the nurse encourage to allow maximal lung expansion?
Correct Answer: A
Rationale: The upright position promotes optimal lung expansion by reducing diaphragm pressure and improving ventilation.
Question 5 of 5
A nurse is preparing to administer dextrose 5% in water (DSW) 100 mL to infuse over 1 hr. The drop factor of the manual IV tubing is 15 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number.)
Correct Answer: B
Rationale: Using the formula Flow rate (gtt/min) = (Volume/Time) × Drop factor, 100 mL / 60 min × 15 gtt/mL = 25 gtt/min.
