Question 1 of 5
A nurse is preparing to administer 40 mEq of potassium chloride in 45% sodium chloride (NaCl) 500 mL IV to infuse 10 mEq/hr. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 125
Rationale:
To determine the mL/hr rate, set up a proportion: (40 mEq / 500 mL) = (10 mEq / x mL). Cross-multiply: 40x = 5000, so x = 5000 / 40 = 125 mL/hr.
Question 2 of 5
A nurse is caring for a client who is postoperative and whose respirations are shallow and 9/min. Which of the following acid-base imbalances should the nurse identify the client as being at risk for developing initially?
Correct Answer: D
Rationale: Shallow, slow respirations cause CO2 retention, increasing the risk of respiratory acidosis.
Question 3 of 5
A nurse is assessing a client who has fluid volume deficit. The nurse should expect which of the following findings?
Correct Answer: D
Rationale: Fluid volume deficit causes hemoconcentration, increasing BUN due to reduced kidney perfusion.
Extract:
Client is admitted following cerebrovascular accident (CVA). Client is alert and oriented. Heart rate regular. Respirations rapid and non-labored. Wheezing auscultated in upper lobes of the lungs. Client is receiving 2 U/min of oxygen via nasal cannula. Right upper and lower extremities flaccid with decreased muscle tone and strength. Client sitting up in a chair for lunch.

Question 5 of 5
A nurse is preparing to administer Ringer's lactate 500 mL IV bolus to infuse over 3 hr. The drop factor of the manual IV tubing is 20 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: 56
Rationale:
Total drops = 500 mL × 20 gtt/mL = 10,000 gtt. Infusion time = 3 hr × 60 min = 180 min. Rate = 10,000 / 180 ≈ 55.6, rounded to 56 gtt/min.
