R-R is irregular

There are absent P waves

PR interval greater than 0.20 seconds in duration.

The PR interval gets longer then drops.

Answer and Explanation

The Correct Answer is C

A. First-degree heart block has a regular R-R interval, meaning the rhythm is typically regular.
B. The presence of P waves is a distinguishing feature of first-degree heart block. Absent P waves are more characteristic of atrial fibrillation or junctional rhythms.
C. First-degree heart block is characterized by a prolonged PR interval greater than 0.20 seconds, but all impulses are still conducted to the ventricles.
D. A progressively lengthening PR interval followed by a dropped QRS complex is indicative of second-degree Mobitz Type I (Wenckebach) heart block, not first-degree heart block.

Correct Answer is B

Explanation

A. Taking a diuretic before bed can lead to nocturia and disrupt sleep. It is usually recommended to take it in the morning.
B. Daily weight tracking helps detect fluid retention, a key indicator of worsening heart failure. A weight gain of 2 lbs in 24 hours or 5 lbs in a week should be reported to the provider.
C. NSAIDs (e.g., naproxen) should be avoided as they can cause fluid retention and worsen heart failure.
D. Sodium intake should be limited to 2 grams (2000 mg) per day, not 4 grams, to help prevent fluid overload.

A. Avoid sick contacts B. You will require prophylactic antibiotics prior to dental procedures. C. You can discontinue your antibiotics once you start feeling better. D. Avoid physical activity for the next six months to allow your heart to heal completely.

Correct Answer is B

Explanation

A. Avoiding sick contacts is generally a good practice, but it is not the primary concern for a client with infective endocarditis. The focus is on preventing bacterial infections that could enter the bloodstream and affect the heart valves.
B. Prophylactic antibiotics are required before dental and invasive procedures to prevent bacterial endocarditis recurrence. The bacteria that cause infective endocarditis can enter the bloodstream through procedures that involve mucosal surfaces.
C. Discontinuing antibiotics when feeling better is incorrect. Infective endocarditis requires a full course of IV antibiotics, often lasting 4 to 6 weeks, to fully eradicate the infection and prevent complications.
D. Avoiding physical activity for six months is unnecessary unless the client has severe cardiac complications. However, clients should monitor for symptoms such as fatigue and consult their provider before engaging in strenuous activities.
