Pharmacokinetics is:

- B. The study of absorption, distribution, metabolism and excretion of drugs
- C. The study of mechanism of drugs

Rationale: Pharmacokinetics focuses on how the body handles a drug, including absorption, distribution, metabolism, and excretion (ADME), distinguishing it from pharmacodynamics, which studies drug effects.
A physician has ordered intramuscular injections of morphine, a narcotic, every 4 hours as needed for pain for a motor vehicle accident victim. The nurse is aware that there is a high abuse potential for this drug, therefore, morphine is categorized as a:
- A. Schedule I drug
- B. Schedule II drug
- C. Schedule III drug
- D. Schedule IV drug
Correct Answer: B
Rationale: Narcotics such as morphine are considered schedule II drugs because of the high abuse potential with severe dependence liability. Schedule I drugs have high abuse potential and no accepted medical use. Schedule III drugs have a lesser abuse potential than schedule II drugs and an accepted medical use. Schedule IV drugs have low abuse potential and limited dependence liability.
The clinic nurse is reviewing a teaching plan for the client receiving an antineoplastic medication. When implementing the plan, the nurse tells the client:
- A. To take aspirin (acetylsalicylic acid) as needed for headache
- B. Drink beverages containing alcohol in moderate amounts each evening
- C. Consult with health care providers (HCPs) before receiving immunizations
- D. That it is not necessary to consult HCPs before receiving a flu vaccine at the local health fair
Correct Answer: C
Rationale: Because antineoplastic medications lower the resistance of the body, clients must be informed not to receive immunizations without a HCP's approval. Clients also need to avoid contact with individuals who have recently received a live virus vaccine. Clients need to avoid aspirin and aspirin-containing products to minimize the risk of bleeding, and they need to avoid alcohol to minimize the risk of toxicity and side effects.
