- A. Reaches the systemic circulation unchanged
- B. Binds to plasma proteins in the blood
- C. Is removed from the body by the kidneys
- D. Produces the maximum therapeutic response
Explanation: Bioavailability is the fraction of an administered dose that reaches systemic circulation in an active form.
Correct answer: Reaches the systemic circulation unchanged- A. To reach the therapeutic concentration quickly
- B. To prevent all adverse drug reactions
- C. To replace a missed dose from yesterday
- D. To maintain the concentration for several weeks
Explanation: A loading dose is larger than the usual maintenance dose and helps achieve a therapeutic blood concentration rapidly.
Correct answer: To reach the therapeutic concentration quickly- A. The drug enters the blood for the first time
- B. The average drug input equals the average drug elimination
- C. The drug is completely removed after every dose
- D. The patient develops an immediate allergic reaction
Explanation: Steady state occurs when the average rate of drug administration equals the average rate of elimination.
Correct answer: The average drug input equals the average drug elimination- A. A lower blood level of the first medicine
- B. A higher blood level of the first medicine
- C. A faster renal excretion of the first medicine
- D. A complete loss of absorption of the first medicine
Explanation: Enzyme inhibition slows the metabolism of the affected medicine, so its blood concentration may rise and toxicity may occur.
Correct answer: A higher blood level of the first medicine- A. Administer the tablet kept in the patient's drawer
- B. Ask the patient which tablet is usually taken
- C. Withhold the dose and clarify the order
- D. Give half a tablet to reduce possible harm
Explanation: An incomplete medication order must be clarified before administration because the drug and strength cannot be verified safely.

- B. Verify the medicine against the order and patient identifiers
- C. Choose the medicine with the shorter name
- D. Ask another patient to identify the package

- B. Take doses at evenly spaced times as prescribed
- C. Take the medicine only when symptoms become severe
- D. Double the next dose whenever one dose is late
Explanation: Evenly spaced doses help maintain the medicine within its intended therapeutic range.
Correct answer: Take doses at evenly spaced times as prescribed- A. All patients absorb and eliminate medicines identically
- B. Age, organ function and genetics can alter drug response
- C. Drug effects depend only on the colour of the tablet
- D. A medicine always has the same effect at every dose
Explanation: Age, liver and kidney function, genetics, nutrition and other medicines can change drug absorption, metabolism, elimination and response.
Correct answer: Age, organ function and genetics can alter drug response- A. Peak concentration
- B. Trough concentration
- C. Loading concentration
- D. Therapeutic response
Explanation: A trough concentration is the lowest drug level in the blood and is measured just before the next dose.
Correct answer: Trough concentration
