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. Hypokalemia: Furosemide is a loop diuretic that works by increasing urinary excretion of sodium, chloride, and water, which can lead to potassium loss. Hypokalemia is a common electrolyte imbalance associated with the use of loop diuretics like furosemide. Potassium depletion can cause various complications, including cardiac dysrhythmias, muscle weakness, and fatigue.

B. Hypocalcemia: Furosemide does not directly affect calcium levels, so hypocalcemia is not a common electrolyte imbalance associated with its use.

C. Hypernatremia: Furosemide promotes the excretion of sodium, so hypernatremia (elevated serum sodium levels) is not typically a concern with its use.

D. Hyperkalemia: Furosemide can cause potassium loss, so hyperkalemia is not a risk associated with its use.

A. "After the surgery, I will have to be careful with heavy lifting for a few weeks." B. "I know that after the surgery, I will only have one testicle left." C. "I will have to take antibiotics as prescribed by my doctor to prevent infection." D. "I will need to avoid showering for a month after the surgery."

Correct Answer is D

Explanation

A. "After the surgery, I will have to be careful with heavy lifting for a few weeks": This statement demonstrates understanding of postoperative precautions, as heavy lifting can strain the surgical site and delay healing.

B. "I know that after the surgery, I will only have one testicle left": This statement indicates awareness of the surgical procedure and its potential outcomes, which is accurate.

C. "I will have to take antibiotics as prescribed by my doctor to prevent infection": This statement reflects understanding of the importance of antibiotic therapy to prevent postoperative infection, which is correct.

D. "I will need to avoid showering for a month after the surgery": This statement is incorrect.

Avoiding showering for a month after surgery is unnecessary and could lead to poor hygiene and potential complications such as infection. The client should be educated that showering is typically allowed after surgery, but they should avoid soaking the incision site in water until it has healed properly.
