The nurse notes that the client's rhythm strip indicates a PR-interval of 0.28 seconds. What is the nurse's analysis of this problem?

2nd degree Mobitz Il

Atrial flutter

Sinus bradycardia

1st degree AV block

Answer and Explanation

The Correct Answer is D

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.

Correct Answer is ["31"]

Explanation

(Volume to be infused (mL) × Drop factor (gtt/mL)) / Time (min).

For the patient prescribed 250 mL of packed red blood cells with a drop factor of 15 gtt/mL over 120 minutes, the calculation would be (250 mL × 15 gtt/mL) / 120 min, which equals 31.25 gtt/min.

Therefore, the nurse should regulate the IV to 31 gtt/min.

A. Visual changes, anorexia B. Polyuria, polydipsia C. Palpitations, shortness of breath D. Systolic murmur, severe anxiety

Correct Answer is C

Explanation

A. These are not typical symptoms of atrial flutter. They may be seen in other conditions like hypertensive crisis or systemic problems, but not as a primary manifestation of atrial flutter.
B. These are classic signs of diabetes or hyperglycemia, not atrial flutter.
C. These are common symptoms of atrial flutter, which results in an irregular heart rhythm and may cause increased heart rate, leading to palpitations and shortness of breath.
D. A systolic murmur is more associated with valve problems, and anxiety could be a result of various issues but is not a typical finding directly caused by atrial flutter.
