Question 1
A patient taking an ACE inhibitor reports developing swelling of
the lips and tongue. Which action is the nurse's priority?
A. Administer the next scheduled dose with food
B. Encourage increased oral fluid intake
C. Hold the medication and seek immediate medical
evaluation
D. Tell the patient that the reaction is an expected adverse
effect
Angioedema involving the lips, tongue, or airway is a potentially
life-threatening adverse reaction associated with ACE inhibitors.
The medication should be discontinued and the patient
evaluated immediately because airway compromise can occur
rapidly. Simply monitoring the patient or administering another
dose is unsafe.
Question 2
,Which laboratory value is most important to monitor in a
patient receiving warfarin therapy?
A. Serum sodium
B. International normalized ratio (INR)
C. Serum amylase
D. Hemoglobin A1C
Warfarin therapy is monitored primarily through the INR, which
reflects the anticoagulant effect of the medication. An
excessively elevated INR increases the risk of bleeding, whereas
an insufficient INR may indicate inadequate anticoagulation.
Dosage adjustments are based on the patient's indication and
target INR.
Question 3
A patient taking metformin is scheduled for a procedure
involving iodinated contrast. What is the primary concern?
A. Severe hypokalemia
B. Hypertension
C. Increased risk of lactic acidosis if renal function deteriorates
D. Acute hyperglycemia caused by metformin
Metformin is associated with a rare but serious risk of lactic
acidosis, particularly when renal function is impaired. Iodinated
contrast can contribute to acute kidney injury in susceptible
,patients. Renal function should therefore be assessed, and
metformin may need to be temporarily withheld according to
the clinical situation and current recommendations.
Question 4
Which medication is considered a short-acting beta-2 agonist
commonly used for rapid relief of acute bronchospasm?
A. Fluticasone
B. Montelukast
C. Albuterol
D. Tiotropium
Albuterol is a short-acting beta-2 adrenergic agonist that
produces bronchodilation and is commonly used as a rescue
medication for acute bronchospasm. Fluticasone is an inhaled
corticosteroid used for long-term control, montelukast is a
leukotriene receptor antagonist, and tiotropium is a long-acting
anticholinergic bronchodilator.
Question 5
Which adverse effect is most concerning in a patient receiving a
high dose of furosemide?
, A. Hypercalcemia
B. Hypokalemia
C. Hypernatremia caused by water retention
D. Bradycardia
Furosemide is a loop diuretic that increases renal excretion of
sodium and water and can significantly increase potassium loss.
Hypokalemia can cause muscle weakness, cardiac dysrhythmias,
and other complications. Electrolytes, renal function, blood
pressure, and fluid status should be monitored.
Question 6
A patient taking a statin reports unexplained muscle pain and
weakness. Which laboratory test should the nurse anticipate?
A. Troponin
B. Serum sodium
C. Creatine kinase (CK)
D. Thyroid-stimulating hormone only
Statins can rarely cause significant skeletal muscle injury,
including rhabdomyolysis. New unexplained muscle pain,
tenderness, or weakness warrants clinical assessment, and
creatine kinase may be obtained when clinically indicated.
Severe muscle injury can lead to acute kidney injury from
myoglobin release.
