Correct.
Q1. What is the study of how drugs enter the body, reach
their site of action, are metabolized, and exit the body called?
A) Pharmacodynamics
B) Pharmacokinetics
C) Pharmacotherapeutics
D) Pharmacognosy
Answer: B) Pharmacokinetics
Rationale: Pharmacokinetics describes the movement of drugs
through the body, including absorption, distribution, metabolism,
and excretion (ADME). Pharmacodynamics (A) is the study of what
drugs do to the body.
Q2. A patient with hypertension is prescribed lisinopril. The
nurse understands that this medication works by which
mechanism of action?
A) Blocking beta-adrenergic receptors
B) Inhibiting angiotensin-converting enzyme (ACE)
C) Blocking calcium channels in cardiac muscle
D) Decreasing sympathetic outflow from the CNS
Answer: B) Inhibiting angiotensin-converting enzyme (ACE)
Rationale: Lisinopril is an ACE inhibitor that blocks the conversion
of angiotensin I to angiotensin II, a potent vasoconstrictor, leading
to vasodilation and decreased blood pressure.
,Q3. A 65-year-old patient with heart failure is prescribed
furosemide. Which lab value requires immediate notification
of the healthcare provider?
A) Sodium 138 mEq/L
B) Potassium 3.0 mEq/L
C) Calcium 9.2 mg/dL
D) Magnesium 2.0 mg/dL
Answer: B) Potassium 3.0 mEq/L
*Rationale: Furosemide is a loop diuretic that causes potassium
loss. A level of 3.0 mEq/L indicates hypokalemia, which can lead to
cardiac dysrhythmias (normal range is 3.5-5.0).*
Q4. A patient is prescribed metformin for type 2 diabetes.
Which statement indicates the patient needs further
teaching?
A) "I will take this medication with my meals."
B) "I will stop taking my medication for a few days if I am having
an X-ray with contrast."
C) "I should report any unusual muscle pain or weakness to my
healthcare provider."
D) "This medication works by increasing insulin production from
my pancreas."
Answer: D) "This medication works by increasing insulin
production from my pancreas."
Rationale: Metformin decreases hepatic glucose production and
increases insulin sensitivity; it does not increase insulin secretion.
Option C is correct because muscle pain can be a sign of lactic
acidosis, a rare but serious side effect.
Q5. A patient with hyperthyroidism is prescribed
methimazole. Which statement indicates understanding of
,this medication?
A) "I should take this medication with food to prevent stomach
upset."
B) "I will need to take this medication for the rest of my life."
C) "This medication will increase my energy levels right away."
D) "I should report any sore throat or fever to my doctor
immediately."
Answer: D) "I should report any sore throat or fever to my
doctor immediately."
Rationale: Methimazole can cause agranulocytosis (dangerously
low WBC count). Sore throat and fever are signs of infection that
must be reported immediately.
Q6. Which medication is known to be nephrotoxic and
requires careful monitoring of renal function?
A) Acetaminophen
B) Vancomycin
C) Metoprolol
D) Loratadine
Answer: B) Vancomycin
Rationale: Vancomycin is an antibiotic known for its potential to
cause nephrotoxicity and ototoxicity. Acetaminophen is hepatotoxic,
not primarily nephrotoxic.
Q7. A patient with gout is prescribed allopurinol. Which
statement by the patient indicates effective teaching?
A) "I will take this medication when I feel joint pain starting."
B) "I should increase my fluid intake to prevent kidney stones."
C) "I will stop taking this medication if I have a flare-up."
D) "This medication will help reduce the inflammation in my joint
immediately."
, Answer: B) "I should increase my fluid intake to prevent
kidney stones."
Rationale: Allopurinol reduces uric acid production. Increased uric
acid concentration in urine can lead to kidney stones, so hydration
is crucial. It is a prophylactic medication, not for acute pain.
Q8. A patient is receiving a blood transfusion. Fifteen minutes
into the transfusion, the patient reports itching and difficulty
breathing. What is the nurse's priority action?
A) Slow the transfusion rate
B) Administer diphenhydramine
C) Stop the transfusion immediately
D) Notify the healthcare provider
Answer: C) Stop the transfusion immediately
Rationale: Itching and dyspnea suggest an acute hemolytic or
allergic transfusion reaction. The priority is to stop the transfusion
to prevent further reaction, then maintain the IV line with normal
saline and notify the provider.
Q9. A patient with chronic kidney disease has a glomerular
filtration rate (GFR) of 25 mL/min. How should the nurse
interpret this finding?
A) Normal kidney function
B) Mildly decreased kidney function
C) Moderately decreased kidney function
D) Severely decreased kidney function
Answer: D) Severely decreased kidney function
*Rationale: Normal GFR is >90 mL/min. A GFR of 15-29 indicates
Stage 4 (severely decreased) kidney function.*
