A nurse is preparing to administer heparin at 1,000 units/hr via continuous IV infusion to a client who had a coronary artery bypass graft. Available is heparin 25,000 units in dextrose 5% in water in 250 mL. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["10"]
ML
The formula to calculate the IV flow rate is:
mL/hr =
(Desired dose (units/hr)×Total volume (mL))/ Available dose
Substituting the given values:
(1,000×250)/25000
= 250,000/25,000
= 10ml/hr

Explanation
A. Scant lochia rubra with a few small clots. Lochia rubra is expected in the early postpartum period, and small clots are normal unless excessive bleeding occurs.
B. Urine output 2,500 mL/day. Increased urine output is expected postpartum as the body eliminates excess fluid retained during pregnancy.

Correct Answer is B
Explanation
A. Identifying past coping skills is important but is not the priority in a crisis situation where the client's safety is at risk.
B. Ensuring the client’s immediate safety is the priority because they may still be in danger from the abusive partner. Crisis intervention focuses first on protecting the client from further harm.
C. Identifying support systems is beneficial for long-term recovery but does not take precedence over ensuring the client’s immediate safety.
D. Encouraging expression of feelings is therapeutic, but the priority is to remove the client from immediate harm before addressing emotional needs.
