The practical nurse (PN) is preparing cefazolin 400 mg IM for a client with a gram-positive infection. The available vial is labeled, "Cefazolin 1 gram," and the instructions for reconstitution state, for IM use, add 2 mL sterile water for injection. The total volume after reconstitution is 2.5 mL.

After reconstitution, how many mL should be administered to the client?

(Enter numeric value only. If rounding is required, round to the whole number, nearest tenths/hundredth).

Regular insulin is the medication of choice for treating DKA. Its main action is to lower blood glucose levels by promoting the uptake of glucose into cells and inhibiting the production of glucose by the liver. Therefore, checking the fingerstick blood glucose level is an important indicator of the effectiveness of the insulin treatment.
A decrease in the blood glucose level indicates that the insulin is working to lower the high blood sugar associated with DKA. This measurement helps the PN assess the response to treatment and adjust the insulin dosage if necessary.
The other actions mentioned are also important assessments in the care of a client with DKA, but they do not specifically evaluate the effectiveness of the insulin dosage:
A. Smelling the client's breath for resolution of a fruity odor is important as it indicates a decrease in ketone production, which is a marker of improving DKA. However, it does not directly evaluate the effectiveness of the insulin dosage.
B. Determining the client's orientation to time and space is part of assessing their neurological status, which is crucial in managing DKA. However, it does not specifically assess the effectiveness of the insulin dosage.
C. Measuring the client's urinary output for an increased volume is important to monitor hydration status and renal function, but it does not directly evaluate the effectiveness of the insulin dosage.

Hives (also known as urticaria) are raised, red, itchy welts on the skin that can be caused by an allergic reaction to medication, including antibiotics. It is essential for the PN to recognize this potentially severe allergic reaction and take immediate action.

Immediate action steps include:

1. Stop the infusion of the intravenous antibiotic immediately.
2. Notify the healthcare provider and report the allergic reaction.
3. Assess the client's airway, breathing, and circulation to ensure there are no signs of respiratory distress or anaphylaxis.
4. Administer prescribed emergency medications if needed (e.g., epinephrine, antihistamines).
5. Monitor the client closely for any further signs of an allergic reaction or anaphylaxis.

The other assessment findings mentioned are also important to address, but they do not require immediate action:

A- Dry mouth with thirst: This may indicate dehydration, which should be addressed by encouraging the client to drink fluids, but it does not pose an immediate threat to the client's safety.

B- Warm skin with elastic turgor: This suggests that the client is adequately hydrated, and the skin's elasticity is normal, which is a positive finding.

C- Low-grade fever with diaphoresis: A low-grade fever indicates a mild elevation in temperature, and diaphoresis (sweating) may be the body's response to regulate temperature. The PN should monitor the client's temperature and assess for other signs of infection, but this finding does not require immediate action
