A nurse is providing prenatal care to a pregnant client. At which time would the nurse expect to screen the client for group B streptococcus infection?

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.

Choice A Reason: This is incorrect because mosquitoes do not transmit HIV. HIV is a virus that infects human cells and cannot survive in insects. Mosquitoes do not inject blood from one person to another when they bite, but only saliva that contains anticoagulants and enzymes.

Choice B Reason: This is incorrect because accidental puncture wounds are not a common mode of HIV transmission. HIV can be transmitted through exposure to infected blood or body fluids, such as through needle sharing, blood transfusion, or occupational injury. However, these cases are rare and can be prevented by using sterile equipment, screening blood products, and following universal precautions.

Choice C Reason: This is correct because sexual contact is the most common mode of HIV transmission. HIV can be transmitted through unprotected vaginal, anal, or oral sex with an infected person, as these activities can involve contact with infected blood, semen, vaginal fluid, or pre-ejaculate.

Choice D Reason: This is incorrect because respiratory droplets do not transmit HIV. HIV is not an airborne virus and cannot be spread by coughing, sneezing, or breathing. HIV cannot be transmitted by casual contact, such as hugging, kissing, or sharing utensils.
