A nurse is preparing to administer gentamicin 2 mg/kg IM to a client who has pelvic inﬂammatory disease and weighs 132 lb. Available is gentamicin injection 40 mg/mL. How many mL should the nurse administer?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["3"]

Use the following formula to calculate the amount of gentamicin to administer:

Volume (mL) = Dose (mg) / Concentration (mg/mL)

First, I need to convert the client's weight from pounds to kilograms. One pound is equal to 0.4536 kilograms. Therefore, 132 lb is equal to 132 x 0.4536 = 59.8752 kg.

Next, I need to multiply the client's weight by the prescribed dose of gentamicin per kilogram. The prescribed dose is 2 mg/kg, so the total dose is 2 x 59.8752 = 119.7504 mg.

Finally, I need to divide the total dose by the concentration of gentamicin in the injection. The concentration is 40 mg/mL, so the volume is 119.7504 / 40 = 2.99376 mL.

To round the answer to the nearest whole number, I need to look at the first decimal place. If it is 5 or more, I round up; if it is less than 5, I round down. In this case, the first decimal place is 9, which is more than 5, so I round up. Therefore, the final answer is 3 mL.

The nurse should administer 3 mL of gentamicin injection to the client.

Correct Answer is C

Explanation

A. Platelets 170,000/mm³ is a normal platelet count in pregnancy. The normal range for platelets in pregnancy is 150,000 to 450,000/mm³⁷⁸.

B. This HbA1c level indicates good control of blood glucose levels over the past 2-3 months. For a pregnant woman with type 1 diabetes, a target HbA1c of less than 6-7% is often recommended to reduce the risk of complications.

C. This blood urea nitrogen (BUN) level is elevated. Normal BUN levels typically range from 7 to 20 mg/dL. Elevated BUN may indicate renal impairment, which can be a concern for a pregnant woman with type 1 diabetes, as it could suggest developing diabetic nephropathy or other kidney-related issues.
D. Hct 34% is a normal hematocrit level in pregnancy. The normal range for hematocrit in pregnancy is 30% to 36%.

A. Maintain airborne precautions in the nursery. B. Place the newborn's foot on a sterile field during a heelstick. C. Place newborn bassinets at least 3 feet apart. D. Allow parents to enter the nursery if they are wearing a mask.

Correct Answer is C

Explanation

When reviewing infection control procedures in a newborn nursery, the nurse manager should instruct the newly hired nurses to place newborn bassinets at least 3 feet apart. This practice helps prevent the spread of infections between infants by minimizing close contact and reducing the risk of droplet transmission.

Option a) Maintaining airborne precautions in the nursery is not necessary unless there is a specific airborne infectious disease outbreak or a newborn with a known airborne infection. Standard precautions, including hand hygiene and proper use of personal protective equipment, are generally sufficient to prevent the spread of infections in a newborn nursery.

Option b) Placing the newborn's foot on a sterile field during a heelstick is not necessary for routine procedures. However, a clean and disinfected surface should be used to perform the heelstick to minimize the risk of introducing pathogens. Sterile fields are typically reserved for sterile procedures in an operating room or other controlled environments.

Option d) Allowing parents to enter the nursery if they are wearing a mask is not a standard infection control practice. In general, only authorized personnel should enter the nursery, and parents or visitors should follow any specific visiting policies in place. If there are concerns about respiratory infections or outbreaks, additional visitor restrictions or requirements may be implemented.
