Pharmacological and Parenteral TherapiesQuestion 1009 of 2368

Why might a pregnant client need dosage adjustments for medications that the kidneys metabolize?

  1. The increased glomerular filtration rate speeds up drug excretion.
  2. Decreased kidney blood flow slows drug excretion.
  3. Decreased bladder tone causes drugs to build up in the body.
  4. Reduced plasma volume makes drugs more concentrated.
Show answer

Correct answer: The increased glomerular filtration rate speeds up drug excretion.

The glomerular filtration rate rises in pregnancy, so the kidneys remove drugs faster. Doses may need adjusting.
