A nurse is caring for a client who is receiving heparin 3,800 units subcutaneously daily. Available is heparin 5,000 units/mL. How many mL should the nurse administer? Round to thenearesttenth

A. Sinus bradycardia: Sinus bradycardia is characterized by a regular rhythm with a heart rate less than 60 beats per minute. In this case, the heart rate is 64 beats per minute, which falls within the normal range, not consistent with sinus bradycardia.

B. Sinus arrhythmia: Sinus arrhythmia typically presents as a variation in the R-R interval with respiration, often seen as an irregularity in the heart rate. The provided characteristics describe a regular rhythm, so sinus arrhythmia is not the correct interpretation.

C. Sinus tachycardia: Sinus tachycardia is characterized by a regular rhythm with a heart rate greater than 100 beats per minute. The heart rate in this case is 64 beats per minute, which is not indicative of sinus tachycardia.

D. Normal sinus rhythm: Normal sinus rhythm refers to a regular rhythm with a heart rate between 60 and 100 beats per minute, P waves preceding each QRS complex, a normal PR interval (0.12 to 0.20 seconds), and normal QRS complex duration (less than 0.12 seconds). The provided characteristics, including regular P waves, regular QRS complexes, a PR interval of 0.16 seconds, and a heart rate of 64 beats per minute, align with a normal sinus rhythm interpretation.

A. Confirm that the room number matches the medical record.Room numbers should never be used as a sole method to identify a client. Room assignments can change, and relying on them could lead to errors.

B. Compare the client identification number to the blood component tag number.Matching the client identification number to the blood component tag ensures the blood is being administered to the correct client. This is a key step in preventing transfusion errors.

C. Verify the provider's prescription with another RN.While this is an important step in the blood administration process, it is not specifically related to identifying the client.

D. Ask the client to verbalize if the blood type is Rh-negative or positive.Clients may not know their blood type, and relying on their verbal confirmation is unsafe. The blood type must be confirmed through laboratory testing and matched with the blood being administered.

E. Scan the barcode on the client's identification band.Scanning the barcode on the client’s identification band is a reliable and commonly used method for verifying the client’s identity in modern healthcare settings. This ensures that the blood is administered to the correct client.
