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. GI intolerance and neutropenia: Antiretroviral therapy can cause gastrointestinal intolerance, including nausea, vomiting, diarrhea, and abdominal pain. Neutropenia, a decrease in neutrophil count, can also occur as a side effect of some antiretroviral medications.
B. T-cell count of 500 and diarrhea: While diarrhea can be a side effect of antiretroviral therapy, a T-cell count of 500 is not necessarily an adverse effect and may indicate effective treatment.
C. Anorexia and constipation: Anorexia and constipation are not commonly associated with antiretroviral therapy. However, gastrointestinal side effects such as diarrhea are more common.
D. Bone demineralization and thrush: Bone demineralization (osteoporosis) can occur as a long- term complication of HIV infection and antiretroviral therapy, but it is not a direct adverse effect of antiretroviral medications. Thrush (oral candidiasis) can occur in HIV-infected individuals, but it is not specifically related to antiretroviral therapy.
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.
