A Nurse Is Preparing To Give An Oral Dose Of Drug X To Treat A Patient's High Blood Pressure.
After Giving The Drug, The Nurse Finds That It Not Only Reduces The Blood Pressure Without
Serious Harmful Effects, But It Also Causes The Patient To Have Nausea And Headache. Based
On This Information, Which Property Of An Ideal Drug Is This Drug Lacking?
A. Effectiveness
B. Safety
C. Selectivity
D. Ease Of Administration
C. Selectivity Correct
The Drug Is Effective In Lowering The Blood Pressure And Safe In That It Does Not Cause
Harmful Effects. However, As Do Most Drugs, It Causes Other Effects Besides The One Response
Desired; Therefore, It Lacks Selectivity. The Oral Form Provides Ease Of Administration.
The Nurse Is Preparing To Give A Drug With Certain Properties. Which Property Of The Drug Is
The Most Compelling Indication That It Should Not Be Given?
A. The Drug Produces An Unwanted Side Effect.
B. The Drug Is Difficult To Administer.
C. The Drug's Effects Are Reversible.
D. The Drug Is Not Effective For Its Intended Purpose.
D. The Drug Is Not Effective For Its Intended Purpose. Correct
If A Drug Is Not Effective, There Is No Justification For Giving It. Some Drugs May Be Given Even
Though They Produce Unwanted Side Effects Or Are Difficult To Administer. Reversible Action Is
A Desired Property For Most Drugs.
,Why Is It Important For Drugs To Have Ease Of Administration?
A. Fewer Administration Errors
B. Less Risk Of Side Effects
C. Greater Chemical Stability
D. Greater Likelihood Of Reversibility
A. Fewer Administration Errors Correct
Ease Of Administration Increases Convenience And Adherence And Can Reduce Administration
Errors. Ease Of Administration Is Not Related To Side Effects, Chemical Stability, Or Reversibility.
The Nurse Teaches A Patient Not To Consume Alcohol With Nitroglycerine, Because The Blood
Pressure Often Drops Significantly When Nitroglycerine Is Taken With Alcohol. Which Drug
Property Does This Illustrate?
A. Chemical Instability
B. Drug Interaction
C. Reversible Action
D. Drug Selectivity
B. Drug Interaction Correct
When Two Or More Drugs Are Taken Together, They Can Interact, Causing Either Increased Or
Decreased Drug Responses. In This Case, Alcohol Would Increase The Nitroglycerine Response.
Chemical Instability, Reversible Action, And Drug Selectivity Are Not Related To This Situation.
When Studying The Impact A Drug Has On The Body, The Nurse Is Reviewing What?
A. The Drug's Pharmacokinetics
B. The Drug's Selectivity
C. The Drug's Pharmacodynamics
,D. The Drug's Predictability.
C. The Drug's Pharmacodynamics Correct
Pharmacodynamics Can Be Thought Of As The Impact Of Drugs On The Body. Pharmacokinetics
Describes The Movement Of Drugs Through The Body. Selectivity Is The Ability Of A Drug To
Elicit Only The Response For Which It Is Given. Predictability Is The Degree Of Certainty About
How A Patient Will Respond To A Certain Drug.
When Studying The Effects Of Drugs In Humans, The Nurse Is Learning About What?
A. Pharmacology
B. Clinical Pharmacology
C. Therapeutics
D. Effectiveness
B. Clinical Pharmacology Correct
Clinical Pharmacology Is The Study Of The Effects Of Drugs In Humans. Pharmacology Can Be
Defined As The Study Of Drugs And Their Interactions With Living Systems. Therapeutics, Also
Known As Pharmacotherapeutics, Is The Use Of Drugs To Diagnose, Prevent, Or Treat Disease Or
To Prevent Pregnancy. The Term Effectiveness Indicates That The Drug Elicits The Intended
Response Or Responses.
Which Statement By A New Nurse Indicates That Further Study Is Indicated?
A. Effectiveness Is The Most Important Property A Drug Can Have.
B. There Is No Such Thing As A Safe Drug.
C. Drugs Are Defined As Illegal Substances.
D. There Is No Such Thing As A Selective Drug; All Medications Cause Side Effects.
Drugs Are Defined As Illegal Substances. Correct
A Drug Is Any Chemical That Can Affect Living Processes. All The Other Statements Are Correct.
, What Is The Ultimate Concern For The Nurse When Administering A Drug?
A. Intensity Of The Response
B. Dosage
C. Route Of Administration
D. Timing Of Administration
A. Intensity Of The Response Correct
The Ultimate Concern For The Nurse When Administering A Drug Is The Intensity Of The
Response, Which Is Determined By The Dosage Size, Route Of Administration, And Timing Of
Administration.
What Is The Objective Of Drug Therapy?
A. To Provide Maximum Benefit With Minimal Harm
B. To Provide Minimum Benefit With Maximum Harm
C. To Provide Total Relief Of Symptoms Regardless Of Harm
D. To Provide As Much Benefit As Possible
A. To Provide Maximum Benefit With Minimal Harm Correct
The Objective Of Drug Therapy Is To Provide Maximum Benefit With Minimal Harm. All Drugs
Have The Potential To Produce Side Effects. Because Drugs Are Not Ideal, We Must Exercise Skill
And Care If Treatment Is To Result In More Good Than Harm
Characteristics Unique To Each Patient Can Influence Pharmacokinetic And Pharmacodynamic
Processes. What Characteristics May Determine The Patient's Response To A Drug? (Select All
That Apply.)
