[ARLKQ]

The physician has written an order for a client for a new antihypertensive drug. Why is it important that the nurse have an understanding of the drug's prototype?
 
  1. Knowledge of the prototype allows the nurse to surmise important information about an unfamiliar drug in the same class.
  2. If the nurse knows the actions and adverse effects of the prototype drug, this information can be relevant to use of the unfamiliar drug.
  3. The safety profile for the prototype is the same as the safety profile for the unfamiliar drug.
  4. Knowledge of the prototype drug's therapeutic or pharmacologic classification can offer useful information about the unfamiliar drug.
  5. Traditional prototype drugs are often older and infrequently prescribed, and the information about them should not be used.

Question 2

The client asks the charge nurse how the health care provider will decide which medication to prescribe. The nurses bases the response on which rationale regarding the ideal drug?
 
  1. Effectively treats, prevents, or cures the client's condition
  2. Is not quickly eliminated by the body so that it can produce its effects over a prolonged period of time
  3. Produces minimal adverse effects
  4. Produces a rapid and predictable response
  5. Is inexpensive and easily accessible

Answer to Question 1

Correct Answer: 1,2,4
Rationale 1: Prototype drugs are the drugs to which all other drugs in the class are compared. Knowledge of the actions and effects of a prototype drug can be extended to an unfamiliar drug in the same class.
Rationale 2: Prototype drugs are the drugs to which all other drugs in the class are compared. Knowledge of the actions and adverse effects of a prototype drug can be extended to an unfamiliar drug in the same class.
Rationale 3: Knowledge of the prototype drug includes therapeutic effects, mechanism of action, adverse effects, and contraindications but may not include an accurate safety profile for the unfamiliar drug.
Rationale 4: Prototype drugs are the drugs to which all other drugs in the class are compared. Knowing how the prototype drug works will reveal important information about the unfamiliar drug.
Rationale 5: Over time, a newer prototype may be chosen, but the older traditional prototype drug still affords valuable information for that class of drugs.
Global Rationale: Prototype drugs are the drugs to which all other drugs in the class are compared. Knowledge of the actions and effects of a prototype drug can be extended to an unfamiliar drug in the same class. Knowledge of the prototype drug may not include an accurate safety profile for the unfamiliar drug. Over time, a newer prototype may be chosen, but the older traditional prototype drug still affords valuable information for that class of drugs.

Answer to Question 2

Correct Answer: 1,4,5
Rationale 1: The goal of pharmacology is to select a drug that will effectively treat, prevent, or cure a condition.
Rationale 2: The goal of pharmacology is to select a drug that will be quickly eliminated by the body after it produces its effects.
Rationale 3: The goal of pharmacology is to select a drug that will produce no short-term or long-term adverse effects.
Rationale 4: The goal of pharmacology is to select a drug that will produce a rapid, predictable response at relatively low doses.
Rationale 5: The ideal drug is affordable and easily accessible.
Global Rationale: The goals of pharmacology include selecting a drug that will: effectively treat, prevent, or cure a condition; produce rapid, predictable responses at relatively low doses; and be affordable and easily accessible. Other goals include selecting a drug that will be quickly eliminated by the body after it produces its effects and will produce no short-term or long-term adverse effects.
