Increases It To Minimize Side Effects.
• C: Baclofen Can Cause Constipation, So Increasing Fiber And Fluid Intake Is
Recommended To Mitigate This Effect.
• D: Alcohol Can Enhance Cns Depressant Effects, So It Should Be Avoided While
Taking Baclofen.
• A: Clients Should Not Abruptly Stop Baclofen; This Can Lead To Withdrawal
Symptoms. Instead, They Should Consult Their Healthcare Provider.
• E: Baclofen Can Be Taken With Or Without Food; There's No Need For It To Be
Taken On An Empty Stomach.
5. A Nurse Is Reviewing The Health Care Record Of A Client Who Reports
Urinary Incontinence And Asks About A Prescription For Oxybutynin. The Nurse
Should Recognize That Oxybutynin Is Contraindicated In The Presence Of Which
Of The Following Conditions?
A. Bursitis
B. Sinusitis
C. Depression
D. Glaucoma
ANS: D. Glaucoma
Rationale: Oxybutynin Is An Anticholinergic Medication That Can Increase Intraocular
Pressure, Making It Contraindicated For Patients With Glaucoma.
• A, B, C: Bursitis, Sinusitis, And Depression Are Not Contraindications For
Oxybutynin Use.
6. A Nurse Is Caring For A Client Who Has A Prescription For Bethanechol To
Treat Urinary Retention. The Nurse Should Recognize That Which Of The
Following Findings Is A Manifestation Of Muscarinic Stimulation?
,A. Dry Mouth
B. Hypertension
C. Excessive Perspiration
D. Fecal Impaction
ANS: C. Excessive Perspiration
Rationale: Bethanechol Is A Muscarinic Agonist, And Muscarinic Stimulation Leads To
Increased Secretions, Including Sweating (Excessive Perspiration).
• A: Dry Mouth Is A Sign Of Anticholinergic Effects, Not Muscarinic Stimulation.
• B: Muscarinic Stimulation Typically Does Not Cause Hypertension; It Can Lead To
Hypotension Due To Vasodilation.
• D: Fecal Impaction Is Not A Direct Result Of Muscarinic Stimulation; It Is More
Related To Decreased Bowel Motility, Which Is Not The Effect Of Muscarinic
Agonists.
7. A Nurse In The Post-Anesthesia Recovery Unit Is Caring For A Client Who
Received A Nondepolarizing Neuromuscular Blocking Agent And Has Muscle
Weakness. The Nurse Should Anticipate A Prescription For Which Of The
Following Medications?
A. Neostigmine
B. Naloxone
C. Dantrolene
D. Vecuronium
ANS: A. Neostigmine
Rationale: Neostigmine Is A Cholinesterase Inhibitor That Is Used To Reverse The Effects
Of Nondepolarizing Neuromuscular Blockers, Restoring Muscle Function.
• B: Naloxone Is An Opioid Antagonist And Not Relevant Here.
• C: Dantrolene Is Used For Malignant Hyperthermia, Not For Reversing
Nondepolarizing Agents.
• D: Vecuronium Is Another Neuromuscular Blocker And Would Not Be Used To
Treat Muscle Weakness Caused By Its Own Effects.
8. A Provider Prescribes Phenobarbital For A Client Who Has A Seizure Disorder.
The Medication Has A Long Half-Life Of 4 Days. How Many Times Per Day
Should The Nurse Expect To Administer This Medication?
A. One
B. Two

9. A Staff Educator Is Reviewing Medication Dosages And Factors That Influence
Medication Metabolism With A Group Of Nurses At An In-Service Presentation.
Which Of The Following Factors Should The Educator Include As A Reason To
Administer Lower Medication Dosages? (Select All That Apply.)
A. Increased Renal Secretion
B. Increased Medication-Metabolizing Enzymes
C. Liver Failure
D. Peripheral Vascular Disease
E. Concurrent Use Of Medication The Same Pathway Metabolizes
ANS: C, E
Rationale:
• C: Liver Failure Reduces The Metabolism Of Drugs, Necessitating Lower Dosages
To Avoid Toxicity.
• E: When Two Drugs Use The Same Metabolic Pathway, They Can Compete, Leading
To Increased Concentrations Of One Or Both, Requiring Dosage Adjustments.
• A: Increased Renal Secretion Generally Doesn't Necessitate Lower Doses; It Often
Relates To Increased Elimination.
• B: Increased Enzyme Activity May Require Higher Doses, Not Lower.
• D: Peripheral Vascular Disease May Affect Drug Distribution But Does Not Directly
Impact The Need For Dosage Adjustments.

Run Down The Cheek.
• D: Placing Drops In The Conjunctival Sac Allows For Better Absorption.
, • E: Closing The Eye Gently Helps Distribute The Medication Evenly Across The
Surface.
• A: Lying On Her Side Is Not Necessary And Can Make The Procedure More
Difficult.
• C: Blinking Right After Administration Can Expel The Drops Rather Than Allowing
Them To Be Absorbed.
11. A Nurse Is Completing Discharge Teaching For A Client Who Has A New
Prescription For Transdermal Patches. Which Of The Following Statements
Should The Nurse Identify As An Indication That The Client Understands The
Instructions?
A. "I Will Clean The Site With An Alcohol Swab Before I Apply The Patch."
B. "I Will Rotate The Application Sites Weekly."
C. "I Will Apply The Patch To An Area Of Skin With No Hair."
D. "I Will Place The New Patch On The Site Of The Old Patch."
ANS: C. "I Will Apply The Patch To An Area Of Skin With No Hair."
Rationale: Applying The Patch To Hairless Skin Ensures Better Adhesion And Absorption
Of The Medication.
