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 C
Explanation
A. "I will be placing electrodes on your breasts": This statement is incorrect and may cause unnecessary concern or discomfort for the client. Electrodes for a 12-lead electrocardiogram are typically placed on the chest, not the breasts.
B. "I will lower the head of your bed so you can lie flat": This statement may be relevant for certain procedures but is not specific to applying electrode gel pads for a 12-lead electrocardiogram.
C. "Relax and try not to move or speak once I have attached the gel pads": This instruction is essential for obtaining a clear and accurate electrocardiogram recording. Movement or talking during the procedure can interfere with the quality of the tracing.
D. "Try to hold your breath until this procedure is complete": This instruction is unnecessary and could cause discomfort or anxiety for the client. There is no need for the client to hold their breath during a standard electrocardiogram procedure.
Correct Answer is B
Explanation
A. Hamburger on a bun, banana: This choice is high in protein and potassium, which may not be suitable for someone with chronic renal disease, as excessive potassium intake can be harmful to individuals with impaired kidney function.
B. Carrots, green leafy vegetables, a pear: This choice is low in potassium and phosphorus, making it suitable for someone with chronic renal disease. Carrots and green leafy vegetables are generally lower in potassium, and a pear is a low-potassium fruit option.
C. Spaghetti with meat sauce, breadstick: This choice may be high in protein and sodium, depending on the sauce and breadstick ingredients, which may not be ideal for someone with chronic renal disease.
D. Cold cuts with bun, blueberries: Cold cuts can be high in sodium, and blueberries are moderately high in potassium, so this choice may not be appropriate for someone with chronic renal disease.
