A nurse is preparing to administer penicillin G benzathine 1.2 million units IM now. The amount available is penicillin G benzathine 600,000 units/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 ["2"]
The correct answer is 2 mL. To calculate the volume to administer, the nurse should use the following formula:
Volume (mL) = Dose (units) / Concentration (units/mL)
Plugging in the given values, we get:
Volume (mL) = 1,200,000 units / 600,000 units/mL
Volume (mL) = 2 mL
Rounding to the nearest whole number, we get 2 mL.

Correct Answer is ["C","D","E"]
Explanation
Choice A: Absence of pain is not a sign of abruptio placenta. Abruptio placenta is a condition where the placenta separates from the uterine wall before delivery, causing bleeding and pain. The pain is usually severe and constant.
Choice B: Insidious onset is not a sign of abruptio placenta. Abruptio placenta is usually a sudden and acute event that occurs in the third trimester or during labor.
Choice C: Dark red vaginal bleeding is a sign of abruptio placenta. The bleeding is caused by the rupture of blood vessels between the placenta and the uterus. The blood may be dark red because it is old or clotted.
Choice D: Rigid uterus is a sign of abruptio placenta. The uterus becomes hard and tense as a result of the bleeding and contraction of the uterine muscles. This can impair the blood flow to the fetus and cause fetal distress.
Choice E: Absent fetal heart tones is a sign of abruptio placenta. The loss of blood and oxygen to the fetus can cause fetal death or stillbirth. Fetal heart tones can be detected by using a Doppler device or a fetoscope.
Correct Answer is C
Explanation
Choice A: A clear liquid diet is not appropriate for a client with hyperemesis gravidarum, which is a severe form of nausea and vomiting during pregnancy that can lead to dehydration, electrolyte imbalance, and weight loss. A clear liquid diet does not provide adequate calories, protein, vitamins, or minerals for the client and the fetus.
Choice B: Administration of diethylstilbestrol is not indicated for a client with hyperemesis gravidarum. Diethylstilbestrol is a synthetic estrogen that was used in the past to prevent miscarriage and premature birth, but it was found to cause serious adverse effects such as vaginal cancer, infertility, and birth defects in the offspring.
Choice C: Total parenteral nutrition is the correct choice because it provides a complete and balanced source of nutrients through a central venous catheter. It is used for clients who cannot tolerate oral or enteral feeding due to severe gastrointestinal disorders such as hyperemesis gravidarum. It helps to prevent malnutrition, dehydration, and ketosis in the client and the fetus.
Choice D: Nothing by mouth is not a suitable option for a client with hyperemesis gravidarum. It can worsen the condition by causing starvation, acidosis, and ketosis. It can also increase the risk of aspiration pneumonia if the client vomits.
