Question 1 of 5
A nurse is monitoring a client who has dehydration and is receiving IV fluid replacement. Which of the following findings should the nurse identify as effectiveness of the treatment?
Correct Answer: B
Rationale: Urine output of 200 mL/4 hr (50 mL/hr) indicates improved kidney perfusion and hydration, suggesting effective treatment.
Question 2 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 3 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?

Rationale: The upright position promotes optimal lung expansion by reducing diaphragm pressure and improving ventilation.
Question 4 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 5 of 5
A nurse is collecting data from a client who has acute gastroenteritis. Which of the following data collection findings should the nurse identify as the priority?
Correct Answer: A
Rationale: A potassium level of 2.5 mEq/L is critically low and can cause life-threatening cardiac dysrhythmias, requiring immediate intervention.
