Elevated ST segment
Wide QRS
Inverted P wave
Abnormally prominent U wave
The Correct Answer is D
A. Elevated ST segment is typically seen with conditions like pericarditis or acute myocardial injury, not hypokalemia.
B. Wide QRS could be related to various conditions, including bundle branch block or electrolyte disturbances, but it is not specifically indicative of hypokalemia.
C. Inverted P wave could be due to atrial arrhythmias but is not a hallmark of hypokalemia.
D. Abnormally prominent U wave is a classic sign of hypokalemia and is often seen following the T wave on an EKG.

- Calculate the total infusion time in minutes:
- 6 hours 60 minutes/hour = 360 minutes
- Calculate the total number of drops:
- 650 mL 10 gtt/mL = 6500 gtt
- Calculate the drops per minute:
- 6500 gtt / 360 minutes = 18.0555gtt/minute
- Round to the nearest whole number:
- 18 gtt/minute
Correct Answer is D
Explanation
A. Evaluating the patient's level of consciousness using the Glasgow Coma Scale is important, but it is secondary to ensuring that the airway is open and that breathing is maintained.
B. Informing the patient that the RN-FNE cannot act on the patient's behalf is unnecessary at this point; the priority is immediate medical intervention.
C. Monitoring vital signs, such as blood pressure and pulse, is crucial but secondary to addressing immediate life-threatening conditions like airway compromise.
D. Assessing the patient's airway is the priority because airway compromise is the most critical issue in emergency care. The RN-FNE must stabilize the patient's airway first before proceeding with other assessments.
