• Nursing assessment, monitoring, adverse effects, and patient education
• **INTRODUCTION***
This assessment is designed to strengthen knowledge and clinical reasoning related to
cardiovascular medications and their nursing management. The questions assess drug
classifications, mechanisms of action, therapeutic effects, adverse effects, contraindications,
monitoring parameters, interactions, patient teaching, and medication-safety principles.
Multiple-choice questions are used to develop recognition, application, analysis, and clinical
decision-making skills. Emphasis is placed on connecting pharmacologic mechanisms with
patient assessment and safe nursing practice. Scenario-based items require interpretation of
clinical findings and selection of the most appropriate nursing action. The explanations
provide concise rationales to reinforce understanding rather than relying solely on
memorization.
SECTION ONE: QUESTIONS 1–100
CARDIOVASCULAR PHARMACOLOGY FOUNDATIONS
Question 1. Which assessment is most important before administering many cardiovascular
medications that can lower heart rate or blood pressure?
A. Bowel sounds and abdominal girth
B. Heart rate and blood pressure
C. Visual acuity and hearing
D. Skin turgor and pupil response
Correct Answer: B. Heart rate and blood pressure
,Explanation: Many cardiovascular medications, including beta-blockers, calcium channel
blockers, antiarrhythmics, and other antihypertensives, can alter heart rate or blood
pressure. Establishing current values helps determine whether administration is appropriate
and provides a baseline for evaluating response.
Question 2. Which term describes the force generated by contraction of the cardiac muscle?
A. Afterload
B. Preload
C. Contractility
D. Conductivity
Correct Answer: C. Contractility
Explanation: Contractility refers to the force of cardiac muscle contraction. Positive inotropic
effects increase contractile force, whereas negative inotropic effects decrease it.
Question 3. A nurse explains that afterload refers to which cardiovascular concept?
A. The amount of blood returning to the heart
B. The resistance against which the ventricles pump
C. The electrical impulse generated by the sinoatrial node
D. The amount of oxygen carried by hemoglobin
Correct Answer: B. The resistance against which the ventricles pump
Explanation: Afterload is the force or resistance the ventricles must overcome to eject blood
into the vascular system. Medications that reduce vascular resistance can therefore decrease
cardiac workload.
Question 4. Which medication effect is described as a positive inotropic effect?
A. Decreased heart rate
B. Decreased conduction
C. Increased force of cardiac contraction
D. Increased peripheral resistance
Correct Answer: C. Increased force of cardiac contraction
Explanation: Positive inotropic effects increase the force of myocardial contraction. Digoxin
is an example of a medication with positive inotropic activity.
,Question 5. Which nursing action is most appropriate when a prescribed cardiovascular
medication has a specific hold parameter that the patient's current assessment meets?
A. Administer the medication and reassess tomorrow
B. Ignore the parameter if the patient is asymptomatic
C. Withhold the medication and follow the prescribed notification process
D. Double the next dose to compensate
Correct Answer: C. Withhold the medication and follow the prescribed notification process
Explanation: Medication parameters exist to promote safe administration. When the
patient's assessment meets a prescribed hold parameter, the nurse should withhold the
medication and notify the appropriate provider according to the order and clinical
circumstances.
Question 6. Which nursing process phase involves determining whether a cardiovascular
medication produced the intended therapeutic response?
A. Assessment
B. Diagnosis
C. Implementation
D. Evaluation
Correct Answer: D. Evaluation
Explanation: Evaluation determines whether the patient's response matches the expected
therapeutic outcome. Cardiovascular evaluation may include blood pressure, heart rate,
edema, intake and output, symptoms, and other relevant findings.
Question 7. Why should nurses review renal function for selected cardiovascular
medications?
A. Renal function can influence medication clearance and dosing
B. Renal function determines the patient's blood type
C. Renal function eliminates the need for vital signs
D. Renal function determines whether a medication is oral
Correct Answer: A. Renal function can influence medication clearance and dosing
Explanation: Several cardiovascular medications are eliminated or substantially affected by
renal function. Reduced renal function can increase medication exposure and may require
dose adjustment or additional monitoring.
, Question 8. Which finding should receive immediate attention in a patient receiving an
anticoagulant?
A. Mild thirst
B. New blood in the urine
C. Occasional hunger
D. Mild fatigue after activity
Correct Answer: B. New blood in the urine
Explanation: Anticoagulants increase bleeding risk. New hematuria can indicate abnormal
bleeding and should be promptly assessed and reported as clinically appropriate. Nurses
should monitor for unusual bruising, blood in urine or stool, and other bleeding
manifestations.
Question 9. Which statement best distinguishes an anticoagulant from a thrombolytic?
A. Anticoagulants prevent or limit clot formation, whereas thrombolytics actively promote
clot breakdown
B. Anticoagulants increase platelet aggregation, whereas thrombolytics decrease blood
pressure
C. Anticoagulants increase clot formation, whereas thrombolytics prevent platelet activation
D. Anticoagulants are used only for hypertension, whereas thrombolytics are used only for
arrhythmias
Correct Answer: A. Anticoagulants prevent or limit clot formation, whereas thrombolytics
actively promote clot breakdown
Explanation: Anticoagulants interfere with coagulation pathways to prevent or limit clot
formation. Thrombolytics such as alteplase promote dissolution of an existing thrombus.
Question 10. Which assessment is particularly important when administering medications
that can affect cardiac rhythm?
A. ECG and electrolyte status
B. Visual acuity only
C. Bowel sounds only
D. Hearing acuity only
Correct Answer: A. ECG and electrolyte status
Explanation: Antiarrhythmic medications can alter cardiac conduction and may themselves
produce dysrhythmias. ECG monitoring and attention to electrolyte abnormalities are
therefore important components of nursing assessment.
