A nurse is assisting with the care of a client who is receiving heparin by IV infusion.
Which of the following medications should the nurse have available in the event of an overdose?
Protamine.
Glucagon.
Oxygen.
Insulin.
The Correct Answer is A
Protamine is a medication that can be used to reverse the effects of heparin in the event of an overdose.
It binds to heparin and neutralizes its anticoagulant effects.
Choice B is not correct because glucagon is used to treat low blood sugar, not heparin overdose.
Choice C is not correct because oxygen is not a medication and is not used to treat heparin overdose.
Choice D is not correct because insulin is used to lower high blood sugar levels, not to treat heparin overdose.

Correct Answer is D
Explanation
“Inject the medication into the abdomen above the level of the iliac crest.” When administering heparin subcutaneously, it is appropriate to inject the medication into the abdomen above the level of the iliac crest 1.
Choice A is not correct because a 1-inch needle may be too long for subcutaneous injection.
A shorter needle, such as a 3/8 to 5/8 inch needle, is typically used for subcutaneous injections.
Choice B is not correct because a 22-gauge needle may be too large for subcutaneous injection.
A smaller gauge needle, such as a 25- or 27-gauge needle, is typically used for subcutaneous injections.
Choice C is not correct because massaging the injection site after administering heparin can increase the risk of bruising and should be avoided.
Correct Answer is B
Explanation
NPH insulin has an onset of action of about 1 to 2 hours, peaks in 4 to 12 hours, and lasts up to 24 hours. Given the administration at 0700, the onset of action would typically occur between 0800 and 0900. Hypoglycemia is most likely to occur during the onset or peak periods due to the insulin's glucose-lowering effect.
Among the options:
- A. 0715: Too early, as NPH insulin's onset is not within 15 minutes.
- B. 0800: Within the onset window (1 hour after administration), making it a plausible time to observe for hypoglycemia.
- C. 0900: Also within the onset window (2 hours after administration), another reasonable time to monitor.
- D. 1000: Slightly beyond the typical onset but still early in the action profile, where hypoglycemia could occur if glucose levels drop.
Since the question asks for the time to observe for hypoglycemia caused by the onset, the earliest time within the onset window is most appropriate. Thus, B. 0800 is the best answer, as it aligns with the start of NPH insulin’s onset period.
Final Answer: B. 0800
