A nurse is assessing a client who is experiencing hypovolemia. Which of the following manifestations should the nurse expect?

This is because at 12 weeks of gestation, the uterus is still low in the pelvis and the fetal heart tones are best audible through the fetal back, which is usually located just above the symphysis pubis. The fetal heart rate at this stage is normally between 120 and 180 beats per minute.
Choice B is wrong because measuring the fundal height is not necessary to determine the placement of the ultrasound stethoscope at 12 weeks of gestation. The fundal height is usually measured from 20 weeks of gestation onwards to assess fetal growth and estimate gestational age.
Choice C is wrong because placing the client in a side-lying position prior to assessing the fetal heart rate is not required at 12 weeks of gestation. This position may be helpful later in pregnancy to improve maternal blood flow and oxygen delivery to the fetus, especially if there are signs of fetal distress or hypoxia.
Choice D is wrong because performing Leopold maneuvers prior to auscultating the fetal heart rate is not appropriate at 12 weeks of gestation.
Leopold maneuvers are a series of four steps to palpate the abdomen and determine the fetal position, presentation, lie, and engagement. They are usually performed after 24 weeks of gestation when the fetus is large enough to be felt through the abdominal wall.

This is because varicella, or chickenpox, is a highly contagious disease caused by the varicella- zoster virus (VZV), which can spread through the air or by direct contact with the fluid from the blisters. A negative air pressure room prevents the air from the room from circulating to other areas of the hospital, reducing the risk of transmission to other patients and staff.

Choice A is wrong because aspirin should not be given to children with chickenpox, as it can cause a serious condition called Reye’s syndrome, which affects the brain and liver. Instead, acetaminophen can be used to reduce fever.

Choice B is wrong because droplet precautions are not enough to prevent the spread of chickenpox. Droplet precautions involve wearing a mask and gloves when in close contact with the patient, but they do not prevent the virus from traveling through the air. Airborne precautions, which include a negative air pressure room and wearing a respirator, are needed for chickenpox.

Choice D is wrong because Koplik spots are not a sign of chickenpox, but of measles, another viral infection that causes a rash. Chickenpox causes an itchy rash with small, fluid-filled blisters that crust over.
