A nurse in an urgent care facility is collecting data from a client who was stung by a wasp. Which of the following findings indicates the client is experiencing anaphylaxis?

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.

The correct answer is a. Dysuria and d. Hematuria.

Choice A rationale:

Dysuria, or painful urination, is a common symptom of cystitis due to the inflammation of the bladder lining.

Choice B rationale:

Bradycardia, or slow heart rate, is not typically associated with cystitis. Cystitis primarily affects the urinary system and does not usually impact heart rate.

Choice C rationale:

Pruritus, or itching, is not a common symptom of cystitis. Itching is more often associated with skin conditions or allergic reactions.

Choice D rationale:

Hematuria, or blood in the urine, can occur with cystitis due to the irritation and inflammation of the bladder lining.
