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. Dyspnea on exertion: Dyspnea on exertion is a common symptom in clients with heart failure and may indicate worsening heart function. While it warrants monitoring and potential intervention, it is not as urgent as rapid weight gain.
B. Increased urination: Increased urination may be expected with the use of diuretics, as they promote the excretion of excess fluid from the body. This finding is not typically concerning unless accompanied by other symptoms.
C. Weight gain of 2 pounds in a week: A weight gain of 2 pounds in a week may indicate fluid retention, but it is not as concerning as a rapid weight gain over a shorter period.
D. Weight gain of 3 pounds in 24 hours: A rapid weight gain of 3 pounds in 24 hours is significant and may indicate fluid overload, potentially leading to exacerbation of heart failure symptoms. It should be reported promptly to the healthcare provider for further evaluation and management.
Correct Answer is C
Explanation
A. "Increase your intake of grapefruit juice."
Grapefruit juice can interact with many medications, including colchicine, potentially increasing the risk of adverse effects or reducing its effectiveness. Therefore, it is not recommended to increase grapefruit juice intake while taking colchicine.
B. "Expect to have increased generalized bruising." Increased bruising is not a common side effect of colchicine.
C. "Monitor for muscle pain."
Colchicine is associated with myotoxicity, which can manifest as muscle pain or weakness. Therefore, the client should be instructed to monitor for signs and symptoms of muscle pain and report them promptly to their healthcare provider.
D. "Take this medication without food if nausea develops."
While colchicine can cause gastrointestinal side effects such as nausea and vomiting, taking it without food may exacerbate these symptoms. It is generally recommended to take colchicine with food to minimize gastrointestinal upset.
