Extract:
Question 1 of 5
A nurse is reviewing the medical record of a client and identifies a serum potassium 6.8 mEq/L (3.5-5 mEq/L). Which of the following medications should the nurse expect to administer?
Correct Answer: C
Rationale: Sodium polystyrene (Kayexalate) treats hyperkalemia by exchanging sodium for potassium in the intestines, promoting potassium elimination, suitable for a dangerously high potassium level of 6.8 mEq/L.
Question 2 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.
Question 3 of 5
A nurse is collecting data from a client who has a calcium level of 12 mg/dL (9-10.5 mg/dL). Which of the following manifestations should the nurse expect?
Correct Answer: B
Rationale: Hypercalcemia depresses neuromuscular function, leading to decreased deep tendon reflexes.
Question 4 of 5
While assessing an older adult patient with fluid excess, the nurse notes the following: T = 98.6°F, P = 92, R = 18, BP = 166/88 mm Hg, bilateral crackles, oxygen saturation = 95%. Which action should the nurse take first?
Correct Answer: C
Rationale: Placing the patient in a high Fowler position maximizes lung expansion and alleviates dyspnea caused by fluid overload.
Question 5 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.
