Your patient is prescribed metronidazole in order to treat their Clostridioides difficile infection. What is the mechanism of action of this drug?
Metronidazole acts by disrupting the DNA and protein synthesis of anaerobic bacteria, resulting in death of susceptible organisms.
A one month old infant presents to their neurosurgical provider for a routine check-up regarding their spina bifida. Which signs and symptoms might you expect an infant or child with spina bifida to exhibit later in life?
Infants with spina bifida may exhibit muscular atrophy that is related to the area of the spinal cord that is affected by the birth defect. This may require them to use special assistive devices for ambulation. They may experience problems with their bladder and bowel control. Some people may have little to no disability whatsoever.
A patient presents to the emergency department with flank pain and receives a diagnosis of renal calculi. Which body system is involved in this diagnosis, and which other symptoms would you expect to accompany flank pain?
Renal calculi are a complication of the kidneys that can cause problems distally throughout the urinary tract. We would expect the patient to experience pain or burning during urination, urinary urgency, hematuria, or cloudy and foul smelling urine. Nausea, vomiting, fever, or chills can indicate signs of developing infection.
