Identify the following Cardiac Rhythm:
Complete Heart Block
Sinus Tachycardia
Ventricular Tachycardia
Idioventricular Rhythm
The Correct Answer is C
A. Complete Heart Block: Complete heart block (third-degree AV block) occurs when there is no communication between the atria and ventricles. The atria and ventricles beat independently, resulting in a very slow ventricular rate. This rhythm is characterized by regular P waves that have no relation to the QRS complexes.
B. Sinus Tachycardia: Sinus tachycardia is a rhythm originating from the sinoatrial node with a heart rate typically between 100-150 beats per minute. The rhythm is regular, and the P waves precede each QRS complex consistently.
C. Ventricular Tachycardia: Ventricular tachycardia is a fast heart rhythm that originates from the ventricles. It is characterized by wide and abnormal QRS complexes with a rate usually between 150-250 beats per minute. There may be no visible P waves, and if present, they are not associated with the QRS complexes.
D. Idioventricular Rhythm: Idioventricular rhythm is a slow rhythm originating from the ventricles with a heart rate usually between 20-40 beats per minute. It has wide and abnormal QRS complexes and no visible P waves.

Correct Answer is D
Explanation
A. "I get chest pain from time to time, but it usually resolves with rest.": While chest pain (angina) can occur with aortic stenosis, it is not as specific as the symptom described in option D. Angina could be related to various other cardiac conditions, including coronary artery disease.
B. "Sometimes when I'm resting, I can feel my heart skip a beat.": Palpitations or feeling like the heart skips a beat are common in many cardiac arrhythmias but are not specifically indicative of aortic stenosis.
C. "My feet and ankles have gotten very puffy the last few weeks.": Edema (puffy feet and ankles) is more commonly associated with right-sided heart failure or other conditions like chronic venous insufficiency, not specifically aortic stenosis.
D. "Whenever I do any form of exercise, I get very short of breath.": Dyspnea on exertion is a classic symptom of aortic stenosis. It occurs because the narrowed aortic valve obstructs blood flow from the left ventricle to the aorta, reducing cardiac output and causing exertional symptoms.
Correct Answer is B
Explanation
A. Assist with passive range of motion exercises: While promoting mobility is important for overall well-being, it may not be the priority in a client with Pneumocystis jirovecii pneumonia, which requires respiratory support and oxygenation.
B. Monitor the pulse oximetry every two hours: Monitoring oxygen saturation is crucial in clients with Pneumocystis jirovecii pneumonia to assess respiratory status and the effectiveness of treatment. Hypoxemia is a common complication and requires prompt intervention.
C. Encourage 1 liter of fluid intake in 24 hours: Encouraging adequate fluid intake is important for hydration, but it may not be the priority over monitoring respiratory status in a client with pneumonia.
D. Encourage the client to focus efforts on discharge: Discharge planning is important but should not take precedence over immediate nursing care priorities such as respiratory assessment and monitoring.
