At the Public Health Department, a nurse administers a measles-mumps-rubella (MMR) vaccine to a 14-month-old child as a routine immunization. Which branch of pharmacology best describes the actions of all three nurses?

  • A. Pharmacoeconomics
  • B. Pharmacotherapeutics
  • C. Pharmacodynamics
  • D. Pharmacokinetics
Correct Answer: B

Rationale: Pharmacology is the study of the biologic effects of chemicals. Nurses are involved with clinical pharmacology or pharmacotherapeutics, which is a branch of pharmacology that deals with the uses of drugs to treat, prevent, and diagnose disease. The radiology nurse is administering a drug to help diagnose a disease. The oncology nurse is administering a drug to help treat a disease. Pharmacoeconomics includes any costs involved in drug therapy. Pharmacodynamics involves how a drug affects the body and pharmacokinetics is how the body acts on the body.

Low doses of aspirin prolong bleeding time by selectively inhibiting synthesis of the following mediator in the platelets:

  • A. Thromboxane Aâ‚‚
  • B. 5-Hydroxytryptamine
  • C. Platelet activating factor
  • D. Prostacyclin

Rationale: Low-dose aspirin irreversibly inhibits COX-1 in platelets, reducing thromboxane Aâ‚‚ production, which promotes platelet aggregation, thus prolonging bleeding time.

A patient with Cushing's syndrome is being treated by X-irradiation of the pituitary. It may take several months of treatment for adequate symptomatic and metabolic improvement. Until that time, which of the following might be administered adjunctively to suppress glucocorticoid synthesis?

  • A. Cimetidine

A nurse is preparing to administer heparin 15,000 units subcutaneously every 12 hr. The amount available is heparin injection 20,000 units/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Do not use a trailing zero.)

  • A. 0.8
  • B. 1
  • C. 0.2
  • D. 0.5
Correct Answer: A

Rationale: Calculation: 15,000 units ÷ 20,000 units/mL = 0.75 mL, rounded to 0.8 mL, matching the answer.

Rationale: Standards of care are defined by state boards of nursing, federal laws regulating health care facilities, The Joint Commission, and professional nursing associations such as the American Nurses Association. Individual hospital policies and procedures incorporate federal and state guidelines into their respective policies and procedures and are often more stringent than state and federal regulations.
