A nurse is preparing to administer mannitol 0.2 g/kg IV bolus over 5 min as a test dose to a client who has severe oliguria. The client weighs 198 lb. What is the amount in grams the nurse should administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

- A. Correct. The nurse should initiate seizure precautions for a client who is at 33 weeks of gestation and has severe gestational hypertension, which is a blood pressure of 160/110 mm Hg or higher on two occasions at least 4 hr apart, or once with signs of end-organ damage. Severe gestational hypertension can lead to preeclampsia, which is a condition characterized by hypertension, proteinuria, and edema, and can progress to eclampsia, which is a lifethreatening complication that involves seizures.

- B. Incorrect. The nurse does not need to initiate seizure precautions for a client who is at 16 weeks of gestation and has a hydatidiform mole, which is an abnormal growth of placental tissue that resembles grape-like clusters. A hydatidiform mole can cause vaginal bleeding, hyperemesis gravidarum, and elevated human chorionic gonadotropin levels, but it does not increase the risk of seizures.

- C. Incorrect. The nurse does not need to initiate seizure precautions for a client who is at 28 weeks of gestation and is experiencing vaginal bleeding, which can have various causes such as placenta previa, placental abruption, or cervical trauma. Vaginal bleeding can indicate a potential hemorrhage, but it does not increase the risk of seizures.

- D. Incorrect. The nurse does not need to initiate seizure precautions for a client who is at 36 weeks of gestation and has a positive group B streptococcal culture, which means that the client has bacteria in their vagina or rectum that can cause infection in the newborn during delivery. A positive group B streptococcal culture requires antibiotic prophylaxis during labor, but it does not increase the risk of seizures.

Choice A rationale:

A client who had blood drawn from the right antecubital area 1 hour ago does not require blood pressure measurement from the left arm. Blood drawing from one arm does not affect the accuracy of blood pressure measurement in the opposite arm.

Choice B rationale:

A client who has a right peripherally inserted central catheter (PICC) line should have blood pressure measured from the opposite arm to avoid disrupting the PICC line.

Choice C rationale:

A client who had dialysis and is using an arteriovenous shunt in the left lower forearm should have blood pressure measured from the opposite arm. Using the arm with an arteriovenous shunt for blood pressure measurement can lead to inaccurate readings and potentially damage the shunt, disrupting the client's dialysis treatment.

Choice D rationale:

A client who had a right hemisphere stroke does not necessarily require blood pressure measurement from the left arm. Stroke location does not impact the choice of the arm for blood pressure measurement; other factors, such as vascular access devices or medical procedures, are more relevant in this context.
