A nurse is caring for a patient being evaluated for sexually transmitted infection (STI).A negative rapid plasma reagin (RPR) indicates that a patient is probably not infected with which STI?
Herpes simplex II.
Syphilis.
Gonorrhea.
Condylomata.
The Correct Answer is B
The correct answer is choice B. Syphilis. A negative rapid plasma reagin (RPR) test indicates that a patient is probably not infected with syphilis, a sexually transmitted infection (STI) caused by the bacterium Treponema pallidum. The RPR test works by detecting the nonspecific antibodies that your body produces while fighting the infection.
Choice A is wrong because herpes simplex II is a viral infection that causes genital herpes, and it is not detected by the RPR test.
Choice C is wrong because gonorrhea is a bacterial infection caused by Neisseria gonorrhoeae, and it is also not detected by the RPR test.
Choice D is wrong because condylomata are genital warts caused by human papillomavirus (HPV), and they are not detected by the RPR test either.
The RPR test is a screening test, and it can give false-positive results due to other conditions or infections. Therefore, a positive RPR test should always be confirmed by a more specific treponemal test, such as TPPA or FTA-ABS. The RPR test can also be used to monitor the treatment response of syphilis, as the antibody levels should decrease after effective antibiotic therapy.

Correct Answer is A
Explanation
The correct answer is choice A: To minimize the patient’s oxygen needs.
A neutral thermal environment is an environment in which a neonate maintains a normal body temperature while minimizing energy expenditure and oxygen consumption.This is important for the wellbeing of neonates, especially those who are preterm or have respiratory insufficiency.
Choice B is wrong because the conversion of glucose to lactic acid is not a desired outcome of a neutral thermal environment.This conversion occurs when there is inadequate oxygen supply to the tissues, resulting in anaerobic metabolism and metabolic acidosis.
Choice C is wrong because the absorption of surfactant from the alveoli is not affected by a neutral thermal environment.
Surfactant is a substance that reduces surface tension and prevents alveolar collapse.It is produced by type II alveolar cells and secreted into the alveoli.
Choice D is wrong because the metabolism of brown fat stores is not a desired outcome of a neutral thermal environment.
Brown fat is a specialized tissue that generates heat by nonshivering thermogenesis in response to cold stress.
It is located in the nape of the neck, between the scapulae, and around the kidneys and adrenals.It increases the metabolic rate and oxygen consumption of neonates.
Correct Answer is A
Explanation
This means that the uterus is constantly contracted and does not relax between contractions.This can cause the placenta to separate from the uterine wall, which is called placental abruption or abruptio placentae.Placental abruption can deprive the baby of oxygen and nutrients and cause heavy bleeding in the mother.
Choice B is wrong because strong uterine contractions every 3-4 minutes are normal during labor and do not indicate placental abruption.
Choice C is wrong because bile-colored vomitus is not a sign of placental abruption, but rather a sign of hyperemesis gravidarum, a severe form of nausea and vomiting during pregnancy.
Choice D is wrong because fetal heart rate acceleration with fetal activity is a normal finding and indicates a healthy baby.Placental abruption can cause fetal distress and a decrease in fetal heart rate.
