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.)
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.

Explanation
Endometritis is an infection of the endometrium, the lining of the uterus, typically occurring after childbirth. When assessing a client with endometritis, the nurse should expect to find uterine tenderness as a common clinical finding. This finding is consistent with endometritis, which is characterized by inflammation and infection of the endometrium. Additional signs and symptoms may include an elevated temperature, increased lochia, foul-smelling lochia, and an elevated WBC count. Prompt identification and treatment of endometritis are important to prevent further complications.
Option a) A temperature of 37.4°C (99.3°F) is within the normal range and does not necessarily indicate endometritis. However, an elevated temperature above 38°C (100.4°F) or a persistent fever may be indicative of an infection and should be further evaluated.
Option b) Scant lochia (minimal vaginal bleeding) is not a characteristic finding of endometritis. In endometritis, lochia is often increased in amount and may have an unpleasant odor.
Option d) A white blood cell (WBC) count of 9,000/mm³ is within the normal range. However, in cases of endometritis, there is usually an elevation in the WBC count as a response to the infection. An elevated or increasing WBC count may be observed.
Correct Answer is D
Explanation
Preparing a toddler for a new sibling can be challenging, but there are some strategies that can help ease the transition and reduce the risk of jealousy or resentment. One of these strategies is to make any major changes in the toddler's routine or environment well before the baby arrives, such as moving to a new bed, starting preschool, or toilet training. This can help the toddler adjust to the change without feeling displaced or threatened by the baby. It can also prevent the toddler from associating the change with the baby and blaming the baby for it¹².
Moving a toddler to a new bed 2 months before the baby comes home is a good example of this strategy. It gives the toddler enough time to get used to sleeping in a different place and feeling comfortable and secure in it. It also avoids making the toddler feel like they are being kicked out of their bed to make room for the baby. The toddler may even feel proud of having a big-kid bed and being more independent¹².
The other options are not appropriate responses by the nurse because they may have negative effects on the toddler's adjustment to the new sibling:
a) "Let your toddler see you carrying the baby into the home for the first time." This is not a good idea because it may make the toddler feel left out or replaced by the baby. The toddler may not understand why they were not with you when you brought the baby home and may feel hurt or angry. A better option is to have someone else carry the baby into the home while you greet your toddler with a hug and a smile. Then, you can introduce your toddler to their new sibling and involve them in welcoming and caring for the baby¹³.
b) "Avoid bringing your toddler to prenatal visits." This is not a good idea because it may make the toddler feel excluded or curious about what is going on. Bringing your toddler to some of your prenatal visits can help them learn more about the baby and feel more connected to them. You can show your toddler pictures of the baby's development, let them hear the baby's heartbeat, or ask them to help you choose clothes or toys for the baby. However, you should also be prepared for your toddler's possible boredom or impatience during long or boring appointments and bring some snacks or activities to keep them entertained¹⁴.
c) "Require scheduled interactions between the toddler and the baby." This is not a good idea because it may make the toddler feel pressured or resentful toward the baby. Forcing your toddler to interact with the baby when they are not ready or interested can backfire and cause more conflict or distance between them. A better option is to follow your toddler's cues and let them decide how much and when they want to interact with the baby. You can also praise your toddler for any positive interactions they have with the baby, such as giving them a gentle kiss, sharing a toy, or singing a song¹³.
