Questions & Verified Answers | Latest Update | Graded A+
1. If a geriatric patient is prescribed a medication that is primarily metabolized
by the liver, what considerations should a healthcare provider take into
account?
The provider should increase the dosage to ensure effectiveness.
The provider should switch to a medication that is only excreted by the
kidneys.
The provider can prescribe the standard dosage without adjustments.
The provider should consider the potential for slower drug
metabolism and adjust the dosage accordingly.
2. If a newborn is prescribed a medication that requires hepatic metabolism,
what considerations should a healthcare provider take into account regarding
the infant's age?
The provider can assume the infant will metabolize the drug as
effectively as an adult.
The provider should avoid all medications for infants under six months.
The provider should increase the dosage for infants under one year.
The provider should consider that the infant may not metabolize the
drug effectively until around one year of age.
3. Describe the significance of the CYP450 enzyme system in the context of
pharmacokinetics.
The CYP450 enzyme system is involved in the distribution of drugs
throughout the body.
, The CYP450 enzyme system is crucial for drug metabolism, as it
helps convert drugs into forms that can be easily eliminated from
the body.
The CYP450 enzyme system is responsible for drug absorption in the
intestines.
The CYP450 enzyme system only metabolizes endogenous
substances, not drugs.
4. What is P-glycoprotein?
A protein component of most drugs
A protein involved in absorption of nutrients through the intestinal
wall
A cell membrane protein that pumps foreign substances and drugs
out of cells and away from the brain
5. What does the first-pass effect specifically refer to in the context of drug
metabolism?
Rapid hepatic inactivation of oral drugs before they reach systemic
circulation.
The absorption of drugs directly into the bloodstream.
The distribution of drugs throughout the body.
The elimination of drugs through urine.
6. What is the significance of the blood-brain barrier in pharmacology?
It prevents the entry of all drugs into the brain.
It regulates the passage of substances between the bloodstream
and the brain.
