Correct Answer is A
Explanation
Choice A rationale:
Digoxin is used to treat heart failure and atrial fibrillation, but it doesn’t directly address the fluid accumulation in the lungs caused by pulmonary edema.
Choice B rationale:
Captopril, an ACE inhibitor, can help reduce fluid buildup and is typically beneficial for patients with pulmonary edema.
Choice C rationale:
Furosemide is a diuretic that helps remove excess fluid from the body, making it a key medication for treating pulmonary edema.
Choice D rationale:
Carvedilol, a beta blocker, can be used to treat heart failure and hypertension, conditions that can contribute to pulmonary edema.
So, the correct answer is A, after analyzing all choices.
Correct Answer is ["C","E","G","H"]
Explanation
Choice A rationale:
The apical pulse rate increased from 90/min to 112/min, which is still within the normal range (60-100 beats per minute). Therefore, it’s not a critical change.
Choice B rationale:
The adolescent’s position, supine with legs straight, is the recommended position after cardiac catheterization to prevent bleeding from the femoral artery puncture site.
Choice C rationale:
The pulses of the right extremity decreased to 2+, indicating reduced blood flow. This is a critical finding and should be reported.
Choice D rationale:
The pain increased from 0 to 2 on a scale of 0 to 10. While any increase in pain should be monitored, a score of 2 is not typically considered severe.
Choice E rationale:
The pressure dressing became saturated with bloody drainage, indicating possible bleeding. This is a critical finding and should be reported.
Choice F rationale:
The respiratory rate increased from 16/min to 18/min, which is still within the normal range (12-20 breaths per minute). Therefore, it’s not a critical change.
Choice G rationale:
The blood pressure decreased from 120/76 mm Hg to 100/52 mm Hg. A significant drop in blood pressure can indicate blood loss or shock. This is a critical finding and should be reported.
Choice H rationale:
The right lower extremity became cool and pale, indicating reduced blood flow. This is a critical finding and should be reported.
So, the correct answer is Choice C, E, G, H, after analyzing all choices. .
