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).

The correct answer is C.

Choice A reason:

Repeating the heel stick for glucose in one hour is not the best first action because it delays necessary treatment and the infant's glucose could drop further, potentially causing harm.

Choice B reason:

Offering nipple feedings of 10% dextrose is not the initial treatment of choice for neonatal hypoglycemia. Oral dextrose gel may be used, but the priority is to provide a source of nutrition, such as breast milk or formula, which offers more sustained glucose levels.

Choice C reason:

Begin frequent feedings of breast milk or formula. This is the first intervention to implement because the infant's current glucose level is below the normal neonatal range of [30 to 60 mg/dL or 1.7 to 3.3 mmol/L], indicating hypoglycemia, which is common in infants of mothers with gestational diabetes. Immediate feeding can help raise the blood glucose level safely.

Choice D reason:

Assessing for signs of hypocalcemia is not the immediate priority. While hypocalcemia can occur in newborns, particularly those with maternal diabetes, the current symptoms and glucose level suggest hypoglycemia is the primary concern. Signs of hypocalcemia include irritability, muscle twitches, jitteriness, tremors, and poor feeding, which can overlap with hypoglycemia symptoms. However, the heel stick glucose level clearly indicates hypoglycemia, which should be addressed first.

A. This is a client care intervention that the PN can assign to the UAP. Transporting a urine culture sample to the laboratory is a routine and non-invasive task that does not require clinical judgment or skill. The UAP should follow the standard precautions and protocols for handling and labeling the specimen.

E. This is a client care intervention that the PN can assign to the UAP. Emptying the bedside drainage unit for a client with an indwelling urinary catheter is a routine and non-invasive task that does not require clinical judgment or skill. The UAP should follow the standard precautions and protocols for emptying, measuring, and recording the urine output.

B. This is not a client care intervention that the PN can assign to the UAP. Obtaining a post-voided residual (PVR) volume is a procedure that requires clinical judgment and skill, as it involves using a bladder scanner or catheterizing the client to measure the amount of urine left in the bladder after voiding. The UAP is not trained or authorized to perform this task, and it should be done by the PN or another licensed nurse.

C.This is not a client care intervention that the PN can assign to the UAP. Teaching the client with fluid restrictions how to measure urine output is an educational activity that requires clinical judgment and skill, as it involves assessing the client's learning needs, providing clear and accurate instructions, and evaluating the client's understanding and compliance. The UAP is not trained or authorized to perform this task, and it should be done by the PN or another licensed nurse.

D.This is not a client care intervention that the PN can assign to the UAP. Irrigating an indwelling urinary catheter for a client with bladder suspension is a procedure that requires clinical judgment and skill, as it involves inserting sterile fluid into the bladder through the catheter to flush out any clots, debris, or bacteria. The UAP is not trained or authorized to perform this task, and it should be done by the PN or another licensed nurse.
