Identify the following Cardiac Rhythm:

Complete Heart Block

Sinus Tachycardia

Ventricular Tachycardia

Idioventricular Rhythm

Answer and Explanation

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. The client has a history of bronchial asthma: Propranolol is a non-selective beta-blocker and can potentially exacerbate bronchospasm in individuals with asthma due to its beta-blocking effects on beta-2 receptors in the bronchioles. Therefore, this finding should be reported to the provider for further assessment and consideration of alternative medications.

B. The client has a history of migraine headaches: Propranolol is commonly used prophylactically to prevent migraine headaches, so this finding is not a contraindication for its use and does not require immediate reporting to the provider.

C. The client has a history of hypertension: Propranolol is often prescribed for hypertension, so this finding is expected and not a cause for concern.

D. The client has a history of hypothyroidism: While propranolol can affect thyroid function tests, a history of hypothyroidism alone is not a contraindication for its use, and it does not

require immediate reporting to the provider. However, thyroid function should be monitored during therapy.

Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"C"}

Explanation

The nurse should first place the client in high Fowler's position to ease the breathing and improve oxygenation, as the client is experiencing increased dyspnea and chest pain. This position allows for better lung expansion and can be a critical immediate intervention. Following this, the nurse should obtain IV access to facilitate the administration of medications and fluids as needed. IV access is essential for the rapid administration of potential treatments, including anticoagulants, which may be required if a pulmonary embolism is confirmed. These actions are prioritized to address the client's immediate respiratory distress and to prepare for further interventions based on the evolving clinical situation. It is important to note that each clinical scenario is unique, and the interventions should be tailored to the client's specific needs and the healthcare provider's clinical judgment.
