During shift report a colleague states that there is 350 mLs remaining in the client's IV and it has to infuse for 2 more hours. The nurse confirms this matches the order. If the drip factor is 12 gtts/ml, what is the current IV rate? DOCUMENT ANSWER IN THIS FORMAT: RATE gtts/min (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

A. Sinus Bradycardia, with First Degree AV block, Rate 40: The rhythm strip shows regular P waves, each followed by a QRS complex, indicating a sinus rhythm. The PR interval is prolonged (greater than 0.20 seconds) but remains consistent across all beats. This confirms a first-degree AV block. The ventricular rate is approximately 40 bpm, consistent with sinus bradycardia.

B. Second Degree AV block – Mobitz I, Rate 40: Mobitz I (Wenckebach) is characterized by a progressively lengthening PR interval followed by a dropped QRS complex. This pattern is not seen here; the PR intervals are consistently prolonged.

C. Second Degree AV block – Mobitz II, Rate 40: Mobitz II involves intermittent dropped QRS complexes without progressive PR prolongation. In the strip, no QRS complexes are missing, ruling out Mobitz II.

D. Third Degree Heart Block, Rate 40: In complete heart block, there is no relationship between P waves and QRS complexes (AV dissociation). Here, the P waves are consistently followed by QRS complexes, indicating intact conduction, even if delayed. This therefore is not a third-degree block.

A. Atrial fibrillation: Atrial fibrillation is characterized by an irregularly irregular rhythm, absence of identifiable P waves, and an unmeasurable PR interval. The ventricular rate can vary (in this case, 92/min), and QRS duration is usually normal. These findings match the classic ECG criteria for atrial fibrillation.

B. Sinus bradycardia: Sinus bradycardia features a regular rhythm, visible P waves before each QRS, and a rate below 60 bpm. The client's rate is 92 and the rhythm is irregular, ruling out this option.

C. Supraventricular tachycardia: SVT typically presents with a regular, rapid rhythm, often over 150 bpm, and P waves may be hidden in the preceding T wave. The client’s rate is 92 with an irregular rhythm, which does not fit SVT.

D. First-degree heart block: First-degree AV block is defined by a prolonged PR interval (>0.20 seconds) with otherwise normal sinus rhythm. In this case, the PR interval is unmeasurable and the rhythm is irregular, making this diagnosis unlikely.
