“A nurse is obtaining a 2-hr postprandial blood glucose from a patient. Which of the following actions should the nurse take?”

Choice A rationale
While it’s true that there may not have been any indication of GBS in earlier prenatal testing, this does not explain why the test was not conducted earlier. GBS can come and go in the body, so a negative test earlier in pregnancy does not guarantee that the woman will still be GBS-negative later in pregnancy.
Choice B rationale
Even if previous deliveries were all negative for GBS, this does not mean that the woman will not have GBS in this pregnancy. GBS can come and go in the body, so each pregnancy is considered separately.
Choice C rationale
GBS is usually asymptomatic in adults, so the woman would not typically report any symptoms of GBS during her pregnancy. This does not explain why the test was not conducted earlier.
Choice D rationale
GBS testing is typically done between 35-37 weeks of gestation. This is because GBS can come and go in the body, so testing during this time frame gives the best prediction of whether or not the woman will have GBS at the time of delivery.

Choice A rationale
A protective environment is not typically required for clients with MRSA141516. This type of precaution is usually used for clients who are severely immunocompromised and need to be protected from any potential sources of infection.
Choice B rationale
Droplet precautions are not typically used for clients with MRSA141516. These precautions are used for diseases that are spread through large respiratory droplets, such as influenza or pertussis.
Choice C rationale
Contact precautions are recommended for clients with MRSA141516. This involves using personal protective equipment and limiting patient movement outside of the room.
Choice D rationale
Airborne precautions are not typically used for clients with MRSA141516. These precautions are used for diseases that are spread through tiny airborne droplets, such as tuberculosis or chickenpox.
