A nurse is caring for a client in a cardiac unit. Using the five criteria for ECG analysis information, the nurse interprets the client's ECG as which of the following rhythm interpretations?

Heart Rate: 59 bpm

Rhythm: Regular

Presence of P waves: One P wave for every QRS complex

PR interval: 0.20 seconds

QRS complex duration: 0.10 seconds

Ventricular tachycardia

Sinus tachycardia

Sinus bradycardia

Normal sinus rhythm

Answer and Explanation

The Correct Answer is C

A) Ventricular tachycardia: Ventricular tachycardia is characterized by a rapid heart rate exceeding 100 bpm, typically arising from abnormal ventricular activity. In this case, the heart rate is 59 bpm, which does not support this interpretation. Additionally, ventricular tachycardia usually presents with wide QRS complexes and no discernible P waves, neither of which is true in this scenario.

B) Sinus tachycardia: Sinus tachycardia is defined by a heart rate exceeding 100 bpm originating from the sinoatrial (SA) node, with a regular rhythm and normal P waves. The heart rate of 59 bpm in this client is too low for a diagnosis of sinus tachycardia, making this option incorrect.

C) Sinus bradycardia: Sinus bradycardia occurs when the heart rate is less than 60 bpm, with a regular rhythm and a normal PR interval and QRS duration. The provided data shows a heart rate of 59 bpm, a regular rhythm, one P wave for every QRS complex, a PR interval of 0.20 seconds, and a QRS duration of 0.10 seconds, which aligns perfectly with the criteria for sinus bradycardia.

D) Normal sinus rhythm: Normal sinus rhythm typically presents with a heart rate of 60-100 bpm, a regular rhythm, and appropriate P waves for each QRS complex. Given the heart rate of 59 bpm, this does not meet the criteria for normal sinus rhythm, as it falls below the acceptable range.

Correct Answer is ["A","B","C","D"]

Explanation

A) "I will apply my compression stockings." Compression stockings are a standard recommendation for clients with peripheral venous disease (PVD). They help improve venous return and reduce symptoms like swelling and discomfort, indicating that the client understands the importance of managing their condition.

B) "I will limit long periods of standing." This statement reflects an understanding of the need to avoid activities that can exacerbate venous stasis and contribute to worsening symptoms in PVD. Limiting long periods of standing helps promote better blood flow and reduces the risk of complications.
C) "I may develop a brownish discoloration to my lower extremities." This statement indicates an awareness of a potential complication of PVD, often caused by venous stasis and pooling of blood. Brownish discoloration, or stasis dermatitis, can occur in the lower extremities, showing the client’s understanding of the condition.

D) "With this problem, I may have lower extremity hair loss." This statement is accurate as well; hair loss on the lower extremities can occur with PVD due to reduced blood flow and oxygen supply to the tissues. This recognition indicates that the client understands the potential effects of their diagnosis.

E) "I will only take my cholesterol lowering medication every other day in the afternoon." This statement reflects a misunderstanding of medication management. Clients with PVD should take prescribed medications as directed to manage their condition effectively, and altering the dosing schedule without consulting a healthcare provider can lead to adverse outcomes.

A. 60 B. 100 C. 90 D. 75

Correct Answer is A

Explanation

To calculate the heart rate based on the rhythm strip, we can use the "six-second method".

Count the number of QRS complexes in a six-second strip.

Multiply this number by 10.

In this case, it appears that there are approximately 6 QRS complexes in a six-second strip.

Therefore, the heart rate is approximately 6 x 10 = 60 beats per minute.
