A nurse is reinforcing discharge teaching with a client regarding selfadministration of regular insulin. What instruction should the nurse include?
Plan to eat a snack 6 hours after insulin administration.
Store opened insulin vials at room temperature for up to 4 weeks.
Warm the insulin vial to dissolve any crystals that develop.
Keep unopened insulin vials in the freezer.
The Correct Answer is B
The correct answer is choice B: Store opened insulin vials at room temperature for up to 4 weeks.
Choice B rationale: Opened insulin vials can be stored at room temperature (59°F to 86°F or 15°C to 30°C) for up to 4 weeks. After this period, the insulin may lose potency, and a new vial should be used.
Choice A rationale: Regular insulin is short-acting, and its peak effect occurs 2 to 3 hours after administration. Eating a snack 6 hours after insulin administration may not be necessary as the insulin would have already reached its peak effect, and blood glucose levels should be monitored accordingly.
Choice C rationale: Warming the insulin vial to dissolve crystals is not recommended. Insulin should be inspected before use, and if crystals or clumps are present, it should be discarded as this could indicate that the insulin has lost its effectiveness.
Choice D rationale: Unopened insulin vials should be stored in the refrigerator (36°F to 46°F or 2°C to 8°C) and should not be frozen. Freezing can cause insulin to lose potency or become ineffective. Once opened, insulin vials can be stored at room temperature for up to 4 weeks, as mentioned in choice B.

Correct Answer is D
Explanation
The correct answer is choice D. The nurse should identify an oral temperature of 39°C (102.2°F) as the priority finding in a client who is postoperative following a total thyroidectomy for hyperthyroidism. An elevated temperature can indicate infection, which is a risk after surgery. The nurse should report this finding to the provider immediately.
Choices A, B, and C are incorrect because moderate amount of serosanguineous drainage on dressings, serum calcium level 9.2 mg/dL, and report of a sore throat, respectively, are expected findings after a total thyroidectomy and do not require immediate action.
Correct Answer is A
Explanation
Epoetin alfa is a medication used to stimulate erythropoiesis, the production of red blood cells. An increase in the client's hemoglobin level indicates that the medication has been effective. The normal range of hemoglobin for adult females is 12-16 g/dL and for adult males is 13.5-17.5 g/dL. A hemoglobin level of 11 g/dL is slightly below the normal range, but it is an improvement from a lower level. Choice B, WBC count 9,000/mm3 is unrelated to the medication and is within the normal range. Choice
C, total calcium 10 mg/dL, and choice D, PT 12 seconds, are also unrelated to the medication and are within the normal range.
Choice B (WBC count 9,000/mm3) is not an answer because it is unrelated to the medication and is within the normal range.
Choice C (total calcium 10 mg/dL) is not an answer because it is unrelated to the medication and is within the normal range.
Choice D (PT 12 seconds) is not an answer because it is unrelated to the medication and is within the normal range.
