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 A
Explanation
A. Irregular pulsations: Premature ventricular contractions (PVCs) are abnormal heartbeats originating in the ventricles, causing irregularities in the heart rhythm. Auscultating the apical pulse during PVCs may reveal irregular pulsations due to the irregular timing of ventricular contractions.
B. Bounding pulsations: Bounding pulsations are typically associated with conditions such as hypertension or aortic valve regurgitation but are not specifically characteristic of PVCs.
C. Tachycardia: PVCs may occur in the setting of tachycardia, but the presence of PVCs themselves does not necessarily indicate a rapid heart rate. The rhythm may be irregular due to PVCs, but the overall heart rate may not be consistently elevated.
D. Bradycardia: PVCs are not typically associated with bradycardia. Bradycardia refers to a slow heart rate, while PVCs involve premature extra beats originating from the ventricles.

Explanation
Client calm not agitated. Grimaces with movement.
No change: While the client is calm and not agitated, grimacing with movement indicates continued discomfort or pain, which remains unchanged.
Oral mucous membranes dry.
No change: Dry oral mucous membranes persist, suggesting ongoing dehydration or inadequate oral hydration.
Axillary temp 102 F (38.9 C), client shivering.
Declined: The axillary temperature has increased from 100.8 F (38.22 C) to 102 F (38.9 C), indicating a worsening of the client's fever. Shivering suggests the body's attempt to generate heat in response to the fever.
Productive cough.
No change: The client continues to have a productive cough, indicating ongoing respiratory congestion or infection.
Coarse rhonchi bilaterally. Crackles in bases.
Declined: The presence of coarse rhonchi bilaterally and crackles in the bases suggests worsening respiratory status, possibly indicating progression of underlying lung disease or development of complications such as pneumonia.
Respirations irregular with periods of apnea.
Improved: The client's respirations, previously irregular with periods of apnea, are now regular, indicating an improvement in respiratory function.
Client resting in recliner. RR 12, regular.
Improved: The client's respiratory rate has decreased from 18 to 12 breaths per minute, and respirations are now regular, suggesting improved respiratory status and possibly reduced distress.
