What is the study of physiochemical properties of drugs and how they influence the body called? -
(ANSWER)Pharmacodynamics
Which statement best describes pharmacokinetics? - (ANSWER)What the body does to the drug after it
is administered
What is another term for biotransformation of a drug? - (ANSWER)Metabolism
>to metabolize connotes the breakdown of a product
A drug given by which route is altered by the first-pass effect? - (ANSWER)Oral
A patient asks the nurse why a lower dose of IV pain medication is being given than the previous oral
dose. What is the nurse's best response to the patient? - (ANSWER)"Medications given intravenously are
not affected by the first-pass effect."
>When drugs with a high first-pass effect are administered orally, a large amount of drug may be
metabolized before it reaches the systemic circulation. The same drug given IV will bypass the liver. This
prevents the first-pass effect from taking place, and therefore more of the drug reaches the circulation.
The nurse understands that drugs exert their actions on the body by what process? -
(ANSWER)>Inhibiting the action of a specific enzyme
>Altering metabolic chemical processes
>Interacting with receptors
Drug half-life is defined as the amount of time required for 50% of a drug to: - (ANSWER)Be eliminated
by the body
Which nursing action will increase the absorption of a medication administered intramuscularly (IM)? -
(ANSWER)Massaging the site of injection after administration

To achieve the most rapid onset of action, the health care provider will prescribe the medication to be
administered by which route? - (ANSWER)IV
Patients with renal failure would MOST likely have problems with which pharmacokinetic process? -
(ANSWER)Excretion
What is the ratio between a drug's therapeutic effects and toxic effects called? - (ANSWER)Therapeutic
index
The nurse knows that which factors will affect the absorption of orally administered medications? -
(ANSWER)>Presence of food in the stomach

>pH balance in the stomach
>Form of drug preparation
END OF CHAPTER 1 NCLEX QUESTIONS - (ANSWER)END OF CHAPTER 1 NCLEX QUESTIONS
When calculating pediatric dosages, the nurse understands which method is MOST accurate for dosing
calculations? - (ANSWER)Dosage calculation by *body surface area* because it takes into account the

nurse understands the greatest risk for medication effects on developing fetuses occurs during which
time period? - (ANSWER)First trimester

nurse anticipates the health care provider will perform which action to minimize the risk of toxicity? -
