Extract:
Question 1 of 5
A nurse is monitoring a client who is dehydrated. Which of the following laboratory findings should the nurse report to the provider?
Correct Answer: C
Rationale: An elevated BUN level (25 mg/dL) is above the normal range (10-20 mg/dL) and indicates dehydration due to increased protein breakdown and decreased renal perfusion, requiring immediate reporting to the provider.
Question 2 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.
Question 3 of 5
A nurse is reviewing the laboratory values for a client who takes spironolactone and notes that the client's serum potassium level is 6.8 mEq/L (3.5 -5 mEq/L). The nurse notifies the provider and anticipates that the provider will provide which of the following instructions?
Correct Answer: C
Rationale: Hyperkalemia can cause life-threatening cardiac dysrhythmias, necessitating an ECG to monitor for abnormalities.
Question 4 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 5 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.
