The nurse is preparing to start a transfusion of packed red blood cells for a client with a hemoglobin of 5.4 g/dL. (normal Female: 11.7-15.5 g/dL; Male: 14-17.3 g/dL). Which IV site should the nurse use?

20-gauge catheter in the right wrist infusing IV antibiotics

18-gauge catheter infusing 20 mEq Potassium Chloride IV

22-gauge catheter in the left forearm infusing 0.9% Normal Saline

20-gauge catheter in the right forearm infusing 0.9% Normal Saline

Answer and Explanation

The Correct Answer is D

A.   The 20-gauge catheter in the right wrist is not ideal for blood transfusions, as wrist veins are smaller and may be less optimal for high-flow transfusions.
B.   An 18-gauge catheter is appropriate for blood transfusions, but the catheter is currently in use for potassium chloride, which would need to be discontinued. The best choice is a separate site.
C.   A 22-gauge catheter is not large enough for blood transfusion; it may cause hemolysis or slow the transfusion rate.
D.   The 20-gauge catheter in the right forearm is an appropriate size for a blood transfusion and is currently infusing normal saline, which does not interfere with the blood transfusion.

Correct Answer is B

Explanation

A. The pacemaker wire for a DDD device is placed in the right atrium and right ventricle, not the left ventricle.
B. This is the correct description of a DDD pacemaker, which has wires in both the right atrium and right ventricle to monitor and pace both chambers when needed.
C. This is incorrect because a DDD pacemaker does not pace both ventricles.
D. This is inaccurate because a DDD pacemaker does not fire with every heartbeat; it only fires when the heart’s natural electrical activity is insufficient.

A. hypermagnesemia. B. hypocalcemia. C. hypokalemia, D. hyperglycemia

Correct Answer is C

Explanation

A. Hypermagnesemia can cause bradycardia and hypotension, but it is less commonly associated with PVCs. This does not align with the lab results provided.
B. Hypocalcemia can cause arrhythmias, but it is not the most likely cause of PVCs in this case, considering other findings.
C. Hypokalemia (low potassium) is a known cause of PVCs. The patient's potassium level is 2.8 mEq/L, which is significantly low and most likely contributing to the PVCs.
D. Although hyperglycemia can affect cardiac function, it is less commonly linked to PVCs compared to electrolyte imbalances, such as hypokalemia.
