A nurse is assisting with care for a client who received a tuberculin skin test 72 hr ago. When collecting data from the test site, which of the following findings indicates a need for further testing?

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.

Answer is: d. Reposition the client.

Explanation: Repositioning the client can help alleviate pain by redistributing pressure and promoting comfort. Since the client's pain level is relatively low (2 on a scale of 0 to 10), this non-pharmacological intervention is an appropriate initial action.

Choice a. is wrong because maintaining the client on bed rest is not an appropriate action for a pain level of 2. Instead, the nurse should encourage the client to mobilize and perform appropriate exercises to prevent complications related to immobility.

Choice b. is wrong because applying a warm, moist compress to the incision area might not be the best action for a client who is 24 hours postoperative, as it could increase the risk of infection and cause discomfort. Cold compresses are often used in the initial postoperative period to reduce swelling and promote comfort.

Choice c. is wrong because administering an additional dose of pain medication is not necessary at this point, as the client's pain level is relatively low. The nurse should consider non-pharmacological interventions first and reassess the client's pain level to determine the need for further pain relief.
