The nurse is assessing the client with a recent pacemaker placement. The client's monitor is displaying what type of rhythm?

The pacemaker is pacing abnormally

Biventricular, pacing in both ventricles

Atrial paced rhythm

Atrial and ventricular pacing

Answer and Explanation

The Correct Answer is D

A.   This would be concerning, but it is not the correct choice. If a pacemaker is functioning abnormally, it would require an assessment and troubleshooting, not simply a routine rhythm.
B.   This is typical for biventricular pacemakers used in heart failure patients, but it would not apply to a patient with a standard pacemaker unless specified. A recent pacemaker placement does not necessarily indicate biventricular pacing.
C.   This is correct if only the atrium is paced; however, in the case of a typical pacemaker like DDD (dual- chamber pacemaker), both the atrium and ventricle are paced.
D.   This is correct for dual-chamber pacemakers (like DDD), which pace both the atrium and the ventricle to coordinate the heart's rhythm.

Correct Answer is B

Explanation

A. Fine crackles - Fine crackles are short, popping sounds usually heard during inspiration, indicative of fluid in the lungs.
B. Wheezes - Wheezes are continuous, high-pitched musical sounds caused by narrowed airways, often seen in asthma, bronchitis, or other respiratory conditions.
C. Rhonchi - Rhonchi are low-pitched, rattling sounds that occur when air flows through thick mucus or secretions in the larger airways.
D. Vesicular sounds - Vesicular breath sounds are normal lung sounds heard over most lung fields during inspiration. They are not continuous and high-pitched.

A. 2nd degree Mobitz Il B. Atrial flutter C. Sinus bradycardia D. 1st degree AV block

Correct Answer is D

Explanation

A. This type of AV block is characterized by a progressively lengthening PR interval until a QRS complex is dropped (a blocked beat). A PR interval of 0.28 seconds could be seen in 2nd degree Mobitz I (Wenckebach), not Mobitz II, which has a more irregular pattern of dropped beats
B. Atrial flutter: Atrial flutter is a type of arrhythmia characterized by rapid atrial rates (typically around 250-350 beats per minute) with a sawtooth pattern of P-waves. It does not relate to the PR interval, but rather the atrial rhythm.
C. Sinus bradycardia: Sinus bradycardia is characterized by a slower-than-normal heart rate (less than 60 beats per minute), but this does not affect the PR interval directly. A normal PR interval (0.12-0.20 seconds) can still be seen in sinus bradycardia, so the prolonged PR interval in this case makes sinus bradycardia less likely.
D. 1st degree AV block: In 1st degree AV block, the PR interval is consistently prolonged, usually more than 0.20 seconds, but it is still a constant, non-variable delay in the conduction between the atria and ventricles. A PR interval of 0.28 seconds (which is longer than normal but consistent) is characteristic of a first-degree AV block, making it the correct answer.
