A nurse is caring for a patient who is in labor and has an epidural anesthesia block. The patient’s blood pressure is 80/40 mm Hg and the fetal heart rate is 140/min.
Which of the following is the priority nursing action?

Choice A rationale

The glomerular filtration rate (GFR) does not recover during the oliguric phase of acute kidney injury (AKI). Recovery of GFR typically occurs during the recovery phase.

Choice B rationale

During the oliguric phase of AKI, urine output is typically less than 400 mL per 24 hours.

Choice C rationale

Renal function is not reestablished during the oliguric phase of AKI. This typically occurs during the recovery phase.

Choice D rationale

Blood urea nitrogen (BUN) and creatinine levels do not decrease during the oliguric phase of AKI. These levels typically increase due to decreased kidney function.

Choice A rationale

Streptococcal pharyngitis, also known as strep throat, is a bacterial infection that causes inflammation and pain in the throat. This condition is spread through respiratory droplets, not through the air, and does not require airborne precautions.

Choice B rationale

Scabies is caused by a mite infestation, not an airborne pathogen. It is spread through direct skin-to-skin contact and does not require airborne precautions.

Choice C rationale

Measles is a highly contagious virus that lives in the nose and throat mucus of an infected person. It can spread to others through coughing and sneezing, and the measles virus can live for up to two hours in an airspace where the infected person coughed or sneezed. Therefore, a patient with measles requires airborne precautions.

Choice D rationale

Pertussis, also known as whooping cough, is a highly contagious respiratory disease caused by the bacterium Bordetella pertussis. It spreads through close contact with respiratory droplets when an infected person coughs or sneezes. It is typically managed with droplet precautions, not airborne precautions.
