A nurse is analyzing a client's electrocardiogram (ECG) strip and identifies the following information: Heart rate: 92/min Rhythm: Irregular P wave:
Unable to identify PR interval:
Unable to measure QRS duration:
0.10 seconds Based upon this information,
thenurse should interpret the client's rhythm as indicating which of the following?
Supraventricular tachycardia
Atrial fibrillation
Sinus bradycardia
First-degree heart block
The Correct Answer is B
A. Supraventricular tachycardia (SVT) typically has identifiable P waves; the absence of P waves suggests a different condition.
B. Atrial fibrillation is characterized by an irregular rhythm, inability to identify P waves, and varying intervals. This interpretation aligns with the client's ECG findings.
C. Sinus bradycardia would show identifiable P waves and a regular rhythm with a heart rate less than 60 bpm, which does not match the provided information.
D. First-degree heart block would also show identifiable P waves and regularity in the rhythm with a prolonged PR interval, which is not indicated here.

Correct Answer is ["B","C","E"]
Explanation
A. Cyanosis of the lips and tongue is not a typical finding in coarctation of the aorta; rather, it is more associated with cyanotic congenital heart defects.
B. Weak or absent femoral pulses are expected due to reduced blood flow to the lower body, as the coarctation typically occurs distal to the left subclavian artery.
C. Bounding pulses in the upper extremities are common because the blood flow to the upper body is increased, leading to stronger pulses.
D. High blood pressure in the lower extremities is not typical; instead, there is often lower blood pressure in the lower body due to the obstruction.
E. Poor feeding and irritability are common symptoms in infants with heart conditions, as they may be in distress or not getting enough blood flow to meet their metabolic needs.
Correct Answer is B
Explanation
A. Doubling the dose if a dose is missed can increase the risk of bleeding and is not recommended for warfarin. Instead, the client should take the missed dose as soon as remembered unless it's almost time for the next dose.
B. Using an electric razor is recommended to minimize the risk of cuts and bleeding, which is particularly important for clients on anticoagulants like warfarin.
C. While increasing fiber intake can be beneficial for overall health, it is not specifically necessary for addressing constipation related to warfarin therapy.
D. While mild nosebleeds may occur, they are not typically common during initial treatment. Clients should be informed to report any unusual or severe bleeding.
