The students demonstrate understanding of this process when they identify that which of the following categories are assigned by the Food and Drug Administration to newly approved drugs? Select all that apply.
- A. Metabolic
- B. Noncontrolled substance
- C. Prescription
- D. Nonprescription
- E. Controlled substance

Rationale: Once drugs are approved for use, the FDA assigns the drug to one of the following categories: prescription, nonprescription, or controlled substance. Metabolite refers to the inactive form of the drug. Noncontrolled substance is a term that is not used.
When reviewing the phases of drug development, the nurse finds a discussion about the postmarketing surveillance phase. Which one of the following activities would the nurse expect to find as being carried out during this phase?
- A. Health care providers report adverse effects to FDA.
- B. Healthy volunteers are involved in the test.
- C. In vitro tests are performed using human cells.
- D. The drug is given to patients with the disease.
Correct Answer: A
Rationale: The postmarketing surveillance phase of drug development encourages health care professionals to report adverse effects of drugs to the FDA using MedWatch. Phase 1 of clinical testing involves 20 to 100 healthy volunteers. In vitro testing of the drug on human or animal cells is done in the pre-FDA phase. In Phase 2 of clinical testing, the drug is given to patients with the disease for which the drug is manufactured.
A nurse is assessing a pregnant client and learns that the client is addicted to cocaine. The nurse informs the client about the risks of cocaine addiction for her fetus. Which of the following would the nurse include?
- A. The child may be born with diabetes.
- B. The child may be born with hypertension.
- C. The child may be born with an addiction to drugs.
- D. The child may be born with CNS defects.
Correct Answer: C
Rationale: The nurse informs the client that children born to mothers using addictive drugs are often born with an addiction to the drug. Children born to mothers who are addicted to cocaine are not known to be born with diabetes, CNS defects, or hypertension.
A patient wants to know about the possible interactions of the various drugs that he has been prescribed for an illness. The nurse explains that the drugs interact with each other and produce an effect that is greater than the sum of their separate actions. Which of the following reactions is the nurse informing about?
- A. Additive drug reaction
- B. Synergistic drug reaction
- C. Antagonistic drug reaction
- D. Toxic drug reaction
Correct Answer: B
Rationale: A synergistic drug reaction occurs when drugs interact with each other and produce a sum greater than the sum of their separate actions. An additive drug reaction occurs when the combined effect of two drugs is equal to the sum of each drug given alone. An antagonistic drug reaction occurs when one drug interferes with the action of another, causing neutralization or a decrease in the effect of one drug. Toxic drug reactions are caused when blood concentration levels exceed the therapeutic levels of a drug.
Which of the following would the nurse identify as a factor that alters drug response in children and infants? Select all that apply.
- A. Slower gastric emptying
- B. Greater surface area
- C. Less protein binding
- D. Decreased body water content
- E. Less cutaneous fat
Correct Answer: A,B,C,E
Rationale: Children and infants are not small adults; therefore, they have altered pharmacokinetics. Factors that alter pharmacokinetics in children include slower gastric emptying, less cutaneous fat, greater surface area, increased body water content, less protein binding, and immature hepatic and renal function.
