Identify the following Cardiac Rhythm:
A. Sinus Tachycardia
A sinus tachycardia is characterized by a sinus P wave at a rate of more than 100 per minute followed by a narrow QRS complex unlike in the strip depicted above.
B. Ventricular Tachycardia
The above ECG strip shows a ventricular tachycardia based on the wide QRS with a rate more than 120 bpm, AV dissociation and the fusion beats.
C. Complete Heart Block
A complete heart block is characterized by QRS complexes being conducted at their own rates and totally independent of the P wave.
D. Idioventricular Rhythm
An idioventricular rhythm is characterized by a slow regular ventricular rhythm with a rate less than 50 bpm unlike in the above strip. It also has a prolonged QRS interval with no P wave.

This is wrong because the ECG leads show ST segment elevation.
B. Stable Angina
Stable angina may present with ST segment depression in an ECG unlike in the strip shown above which depicts an ST segment elevation.
C. STEMI
This is correct because of the ST segment elevation.
D. Unstable Angina

A nurse is teaching a client who has a new diagnosis of atrial fibrillation. The nurse should include which of the following in the education?
A. Check your skin for increased bruising
This is important because AFib can lead to blood clots, which may cause bruising or other skin changes.
B. Missing 1 dose of medication is not a risk
Missing doses of medication can increase the risk of complications in atrial fibrillation.
C. The client may develop hypothyroidism.
Hypothyroidism is not directly related to AFib. Therefore, this information is not relevant for AFib education.
D. Hypertension is not a risk factor
Hypertension is a risk factor for atrial fibrillation.
