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.

Correct Answer is C
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
A pudendal nerve block is a local anesthetic administered to block the pudendal nerve, which supplies sensation to the perineum and external genitalia. It is commonly used during childbirth to provide pain relief during the second stage of labor.
An adverse effect of a pudendal nerve block is a decreased ability to bear down, or a decreased ability to push effectively during labor. This is because the block affects the nerves responsible for the contraction of the pelvic floor muscles, which are necessary for effective pushing during delivery.
Option a) Uterine hyperstimulation is not an adverse effect of a pudendal nerve block. Uterine hyperstimulation refers to excessive contractions of the uterus, often caused by medications such as oxytocin. Pudendal nerve block does not directly affect uterine contractions.
Option b) Maternal hypertension is not an adverse effect of a pudendal nerve block. Hypertension refers to
high blood pressure, and it is not typically associated with a pudendal nerve block.
Option c) Fetal bradycardia is not a common adverse effect of a pudendal nerve block. Fetal bradycardia refers to a slow heart rate in the fetus. While fetal heart rate monitoring is important during labor, bradycardia is not typically associated with a pudendal nerve block.
