A nurse is reinforcing teaching to a client who is pregnant regarding a 1-hr glucose tolerance test (GTT). Which of the following statements by the client indicates an understanding of the test?

Choice A reason:

The client stating, "This test is to check if my baby has diabetes,” indicates a misunderstanding of the purpose of the 1-hr glucose tolerance test (GTT). The test is performed to screen for gestational diabetes in the mother, not to check the baby's diabetes status. Rationale: Gestational diabetes is a condition where high blood sugar levels develop during pregnancy, and it can affect both the mother and the baby's health.

Choice B reason:

The client mentioning, "If the result is higher than normal, I will need to be on insulin the rest of my life,” demonstrates a misconception about the implications of the 1-hr GTT. The 1-hr GTT is a preliminary screening test, and if the results are higher than normal, it indicates the need for further evaluation, but it does not immediately mean a lifetime dependence on insulin. Rationale: Insulin therapy may be required for managing gestational diabetes in some cases, but not necessarily for the rest of the mother's life.

Choice C reason:

The client saying, "If I forget and eat before the test, then I won't be able to have the test done,” indicates a misunderstanding of the test procedure. The 1-hr GTT requires fasting before the test, typically for 8 to 14 hours, to get accurate results. However, if the client mistakenly eats before the test, it doesn't mean they cannot have the test done at all; they may need to reschedule it after an appropriate fasting period. Rationale: Fasting is crucial for accurate glucose level measurement during the test.

Choice D reason:

The client stating, "If the results are high, then I need another test to see if I have gestational diabetes,” demonstrates a correct understanding of the 1-hr GTT. If the initial screening test shows elevated glucose levels, further testing, such as the 3-hour glucose tolerance test (GTT), is required to confirm the diagnosis of gestational diabetes. Rationale: The 3-hour GTT is a more comprehensive diagnostic test used to confirm or rule out gestational diabetes.

Choice A reason:

The nurse should not reinforce to the client that they should not breastfeed after delivery. Group B streptococcus (GBS) is not transmitted through breast milk. It is crucial for infants born to GBS-positive mothers to receive appropriate prophylaxis, but breastfeeding is not contraindicated.

Choice B reason:

The nurse should maintain contact precautions for the client. Group B streptococcus is a highly contagious bacterium, and taking precautions can help prevent its transmission to other patients and healthcare workers.

Choice C reason:

The nurse does not need to obtain a pharyngeal culture from the client. Group B streptococcus colonization typically occurs in the genital and gastrointestinal tracts, not in the pharynx. Therefore, a pharyngeal culture would not be relevant in this situation.

Choice D reason:

This is the correct action the nurse should take. The client tested positive for group B streptococcus, which puts the newborn at risk of infection during labor and delivery. The standard protocol is to administer intravenous antibiotic prophylaxis to the mother during labor to reduce the risk of transmission to the baby.
