Extract:
Question 1 of 5
A nurse is reviewing the laboratory results of a client who is taking a loop diuretic and notes the client's potassium level is 3.0 mEq/L (3.5-5 mEq/L). Which of the following physiological responses should the nurse expect related to the client's hypokalemia?
Correct Answer: A
Rationale: Hypokalemia can impair cardiac muscle function, leading to potentially life-threatening cardiac dysrhythmias.
Question 2 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 3 of 5
A nurse is preparing to administer dextrose 5% in water IV to infuse at 100 mL/60 min. 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, 100 mL/60 min × 60 gtt/mL = 100 gtt/min.
Question 4 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 5 of 5
The nurse is preparing to start an IV on a newly admitted patient. Which action by the nurse places the patient at risk for infection?
Correct Answer: C
Rationale: Blowing on the cleansed area introduces bacteria from the nurse's breath, increasing infection risk.
