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 D

Explanation

When caring for a client with preeclampsia receiving magnesium sulfate, the nurse should instruct the client to report any increased muscle weakness. Magnesium sulfate is a medication commonly used to prevent and treat seizures in clients with preeclampsia. However, one of the side eﬀects of magnesium sulfate is muscle weakness. If the client experiences an increase in muscle weakness, it could indicate magnesium toxicity, which requires immediate medical attention.

Option a) Increased respiratory rate is not typically associated with magnesium sulfate administration. However, respiratory depression is a potential side eﬀect, so a decreased respiratory rate should be reported.

Option b) Increased fetal movement is generally considered a positive sign of fetal well-being and is not a concern that needs to be reported.

Option c) Increased urinary output is not typically a concerning finding. In fact, maintaining adequate urine output is desired in clients with preeclampsia to ensure proper kidney function. However, a sudden decrease in urinary output or signs of dehydration should be reported.

A. A client who has preeclampsia and a creatinine level of 1.1 mg/dL B. A client who has hyperemesis gravidarum and a sodium level of 110 mEq/L C. A client who has diabetes mellitus and an HbA1C of 5.8% D. A client who has placenta previa and a hematocrit of 35%

Correct Answer is B

Explanation

Among the given options, the client who has hyperemesis gravidarum and a sodium level of 110 mEq/L should be assessed first. Hyperemesis gravidarum is a condition characterized by severe and persistent vomiting during pregnancy, leading to dehydration and electrolyte imbalances. A sodium level of 110 mEq/L indicates hyponatremia, which is an abnormally low level of sodium in the blood.

Hyponatremia can lead to serious complications, including neurological symptoms such as confusion, seizures, and coma. Prompt assessment and intervention are necessary to correct the electrolyte imbalance and prevent further complications.

Option a) A client with preeclampsia and a creatinine level of 1.1 mg/dL should be monitored closely, as elevated creatinine levels can indicate impaired kidney function. However, in this scenario, the client with hyperemesis gravidarum and severe hyponatremia requires more immediate attention due to the potential for neurological complications.

Option c) A client with diabetes mellitus and an HbA1C of 5.8% may require further management and monitoring, but it does not present an immediate risk or urgency compared to the client with hyperemesis gravidarum and severe hyponatremia.

Option d) A client with placenta previa and a hematocrit of 35% may need close monitoring for potential bleeding, but it does not pose an immediate threat compared to the client with hyperemesis gravidarum and severe hyponatremia.

Therefore, the nurse should assess the client who has hyperemesis gravidarum and a sodium level of 110 mEq/L as the first priority due to the risk of complications associated with severe hyponatremia.
