The client is curious about the movement of the medication through his body. The client asks the nurse the name of the concept in which the medication moves from the site of administration, across body membranes, and to the circulating fluids/bloodstream.
How should the nurse best respond to explain this pharmacokinetic concept?
Duration of action
Absorption
Diffusion
Onset of action
The Correct Answer is B
A. Duration of action refers to the length of time the medication has an effect, not how it moves through the body.
B. Absorption is the process by which a drug moves from the site of administration into the bloodstream or circulating fluids.
C. Diffusion is part of absorption, but absorption is the broader term that encompasses all mechanisms by which the drug enters the bloodstream.
D. Onset of action refers to the time it takes for the medication to begin working, not the movement of the drug through the body.

Correct Answer is D
Explanation
A. Distribution: This phase involves the transportation of the drug throughout the body after absorption, not removal.
B. Metabolism: This phase involves the chemical alteration of the drug in the body, often in the liver, not its removal.
C. Absorption: This phase involves the drug entering the bloodstream after administration.
D. Excretion: This is the phase where the drug or its metabolites are removed from the body through various routes such as the kidneys, gastrointestinal tract, skin, or lungs.
Correct Answer is ["A","B"]
Explanation
A. BUN is a waste product of protein metabolism that is excreted by the kidneys. Elevated BUN levels can indicate impaired kidney function or kidney dysfunction. Since kidney dysfunction can affect the elimination of waste products, monitoring BUN is essential to assess the kidney's ability to filter and excrete waste.
B. Creatinine is a waste product of muscle metabolism that is filtered out by the kidneys. It is one of the most reliable indicators of kidney function. When kidney function is impaired, creatinine levels rise in the blood because the kidneys are unable to excrete it efficiently.
C. Lipid panel: This is unrelated to the metabolism of medications.
D. Blood glucose: Blood glucose levels are important for diabetes management but are not directly impacted by kidney dysfunction in relation to medication response.
