HESI PHARMACOLOGY PRACTICE EXAM 3
A client with mild parkinsonism is started on oral amantadine
(Symmetrel). What statement accurately describes the action of this
medication?
dopamine in central nervous system is increased
A 52-year-old client is admitted to the hospital for possible duodenal
ulcers. The healthcare provider prescribes ranitidine hydrochloride
(Zantac) 150 mg BID PO. Which data would indicate that this medication is
effective?
Within 4 hours after meals, the client denies having pain.
A 78-year-old client with congestive heart failure receives the cardiac
glycoside digoxin (Lanoxin) 0.25 mg PO daily. Which observation by the
nurse indicates that the medication has been effective?
Clear breath sounds anteriorly and posteriorly
Minocycline (Minocin) 50 mg every 8 hours is prescribed for an adolescent
girl diagnosed with acne. The nurse discusses self-care with the client
while she is taking the medication. Which teaching points should be
included in the discussion? (Select all that apply.)
Report vaginal itching or discharge.
Protect skin from natural and artificial ultraviolet light.
Avoid driving until response to medication is known.
Use a nonhormonal method of contraception if sexually active.
The nurse is assessing a stuporous client in the emergency department who
is suspected of overdosing with opioids. Which agent should the nurse
prepare to administer if the client becomes comatose?
Naloxone hydrochloride (Narcan)
The healthcare provider prescribes captopril (Capoten) 37.5 mg. The
medication is available in 25 mg tablets. What should the nurse administer?
1½ tablets
,A client who is HIV positive is receiving epoetin (Epogen) for management
of anemia secondary to zidovudine (AZT) therapy. Which laboratory
finding is most important for the nurse to report to the healthcare
provider?
Hematocrit (HCT) of 58%
A 75-year-old male client taking hydrochlorothiazide (HCTZ) is admitted
to the hospital having "palpitations" and "skipped heart beats." What is the
most likely cause of these symptoms given the client's medication history?
Hypokalemia
Which parameter is most important for the nurse to check prior to
administering a subcutaneous injection of heparin?
A. Heart rate
B. Urinary output
C. Activated partial thromboplastin time (aPTT)
D. Prothrombin time (PT) and international normalized ratio (INR)
C. Activated partial thromboplastin time, commonly referred to as aPTT
Rationale:
The laboratory value that measures heparin's therapeutic anticoagulation
time is the aPTT (C). (A) should be checked before the administration of
digoxin. (B) is valuable information but not a parameter measured for
heparin therapy. (D) is evaluated during anticoagulation therapy using
sodium warfarin (Coumadin).
A client is prescribed a cholinesterase inhibitor, and a family member asks
the nurse how this medication works. Which pharmacophysiologic
explanation should the nurse use to describe this class of drug?
Improves nerve impulse transmission
In developing a nursing care plan for a 9-month-old infant with cystic
fibrosis, the nurse writes a nursing diagnosis of Alteration in nutrition: less
,than body requirements, related to inadequate digestion of nutrients.
Which intervention would best meet this child's needs?
Give pancrelipase (Cotazym-S) capsule mixed with applesauce before each
meal.
When providing client teaching about the administration of
methylphenidate (Ritalin) to the mother of a child diagnosed with
attention-deficit/hyperactive disorder (ADHD), what instruction should
the nurse include in the teaching plan?
Offer the child the medication before eating breakfast and after eating
lunch.
Alteration of which laboratory finding represents achievement of a
therapeutic goal for heparin administration?
Partial thromboplastin time
The charge nurse is reviewing the admission history and physical data for
four clients newly admitted to the unit. Which client is at greatest risk for
adverse reactions to medications?
A. 30-year-old man with a fracture
B. 7-year-old child with an ear infection
C. 75-year-old woman with liver disease
D. 50-year-old man with an upper respiratory tract infection
A. 75-year-old woman with liver disease
Rationale:
Impaired hepatic metabolic pathways for drug and chemical degradation
place (C) at greatest risk for adverse reactions to medications based on
advancing age and liver disease. (A and D) have no predisposing factors,
such as genetics, pathophysiologic dysfunction, or drug allergies, that
would increase the risk for cumulative toxicity or adverse drug reactions.
(B) is at risk for dose-related adverse reactions but is at less risk than (C).
, The healthcare provider prescribes ipratropium (Atrovent) for a client. An
allergic reaction to what other medication would cause the nurse to
question the prescription for Atrovent?
Atropine sulfate (Atropine)
68-year-old client has been diagnosed with open-angle glaucoma. The
healthcare provider prescribes pilocarpine (Isopto Carpine) eye drops.
What action of this drug makes it a useful treatment for the client's
condition?
The outflow of aqueous humor in the eyes is increased.
The nurse is preparing to apply a surface anesthetic agent for a client.
Which action should the nurse implement to reduce the risk of systemic
absorption?
A. Apply the anesthetic to mucous membranes.
B. Limit the area of application to inflamed areas.
C. Avoid abraded skin areas when applying the anesthetic.
D. Spread the topical agent over a large surface area.
C. Avoid abraded skin areas when applying the anesthetic
Rationale:
To minimize systemic absorption of topical anesthetics, the anesthetic
agent should be applied to the smallest surface area of intact skin (C).
Application to the mucous membranes poses the greatest risk (A) of
systemic absorption because absorption occurs more readily through
mucous membranes than through the skin. Inflamed areas generally have
an increased blood supply, which increases the risk of systemic absorption,
so (B) should be avoided. A large surface area increases the amount of
topical drug that is available for transdermal absorption, so the smallest
area should be covered, not (D).
The healthcare provider prescribes the anticonvulsant carbamazepine
(Tegretol) for a client with a seizure disorder. The nurse should instruct the
client to notify the healthcare provider if which condition occurs?
