A nurse in an assisted-living facility reinforcing teaching with staff members about preparing for an external chemical disaster. Which of the following instructions should the nurse include?

A) Inject 15 units of air into the regular insulin vial:
When drawing insulin from both NPH (a long-acting insulin) and regular insulin (a short-acting insulin), the nurse should first inject air into the NPH insulin vial (which is the intermediate-acting insulin) and then inject air into the regular insulin vial. This technique helps to prevent contamination of the regular insulin vial with NPH insulin. After injecting air into the regular insulin vial, the nurse would then withdraw the regular insulin first and then the NPH insulin to avoid contamination of the regular insulin with the NPH insulin.

B) Withdraw 10 units of NPH insulin:
This action is premature, as the nurse has not yet injected air into the regular insulin vial. The correct sequence involves injecting air into both vials before withdrawing any insulin. Therefore, withdrawing NPH insulin at this stage is not the correct next step.

C) Verify the dosage with another nurse:
While verifying the insulin dosage with another nurse is a good practice for ensuring medication safety, this action is not the immediate next step after injecting air into the NPH insulin vial. The priority is to follow the correct sequence of air injection into the vials before withdrawing the insulin. Verification can occur after the insulin is drawn.

D) Place the cap over the needle:
Placing the cap over the needle is a safety step that is generally performed after withdrawing the insulin and preparing the injection. However, this is not the next step in the process of mixing or drawing insulin, so it is not the correct action to take at this point.

A) Occasional small clots in the urine:
Occasional small clots can be expected after a transurethral resection of the prostate (TURP) due to the surgical trauma to the prostate and surrounding tissues. However, any change in the nature or frequency of clots, or if they become larger, should be reported, but small clots are not immediately concerning in the early postoperative period.

B) Urine output of 300 mL over 8 hr:
This urine output is within a reasonable range. While urine output may be initially monitored closely after TURP, a volume of 300 mL over 8 hours does not constitute a concerning finding. It may be less than expected, but it is not an emergency. The nurse should continue to monitor urine output, but this is not immediately concerning unless the client has a significantly reduced or absent output.

C) Dark red urine:
Dark red urine is a concerning finding as it may indicate excessive bleeding or hemorrhage, especially within the first 24 hours after TURP. While some initial hematuria (blood in the urine) is common, the urine should not remain dark red or worsen. This could indicate active bleeding or a clot obstructing the urinary flow, which requires immediate intervention and reporting to the healthcare provider to prevent complications.

D) Frequent urge to urinate:
A frequent urge to urinate is not an unusual finding following TURP, as the bladder may be irritated due to the catheter or residual inflammation from the surgery. While it is a discomforting symptom, it is typically not an immediate concern and often resolves as the healing process progresses. However, persistent or painful urination may require further evaluation.
