CMS Pharmacology Proctored Exam Practice
Questions With Verified Answers & Rationales
LATEST UPDATE THIS YEAR
CMS Pharmacology Proctored Exam Overview
The Content Mastery Series (CMS) Pharmacology exam is designed to assess your knowledge of
pharmacological principles, medication administration, side effects, interactions, and nursing
considerations. The exam typically covers:
• Drug Classifications & Mechanisms of Action – How different drug classes work (e.g.,
ACE inhibitors, beta-blockers, anticoagulants, antibiotics)
• Medication Administration & Safety – Routes, dosage calculations, rights of medication
administration, and error prevention
• Pharmacokinetics – Absorption, distribution, metabolism, and excretion of drugs
• Drug Interactions & Contraindications – Recognizing significant drug-drug and drug-
food interactions
• Side Effects & Adverse Reactions – Identifying and managing common and life-
threatening adverse effects
• Client Education – Teaching clients about proper medication use, storage, and
monitoring
• Therapeutic Drug Monitoring – Labs and parameters for specific medications (e.g.,
heparin, warfarin, digoxin, lithium)
100 Realistic Practice Questions & Rationales
Section 1: Cardiovascular & Anticoagulant Pharmacology (Questions 1–20)
1. A nurse is caring for a client receiving a continuous IV infusion of heparin. Which of the
following laboratory values should the nurse monitor to evaluate the effectiveness of the
therapy?
,Page 2 of 200
A) Activated partial thromboplastin time (aPTT)
B) International normalized ratio (INR)
C) Platelet count
D) Prothrombin time (PT)
Answer: A
Heparin therapy is monitored using the aPTT, with a therapeutic goal typically 1.5 to 2.5 times
the normal control value. INR is used to monitor warfarin therapy. Platelet count is monitored to
detect heparin-induced thrombocytopenia (HIT), but it does not measure therapeutic effect. PT
monitors the extrinsic pathway and is used for warfarin monitoring.
2. A nurse is providing teaching to a client who has a new prescription for warfarin. Which of
the following statements by the client indicates a need for further teaching?
A) "I will use a soft toothbrush to brush my teeth."
B) "I will avoid eating large amounts of green leafy vegetables."
,Page 3 of 200
C) "I will take ibuprofen for my headaches."
D) "I will report any unusual bleeding to my provider."
Answer: C
Ibuprofen (NSAID) increases the risk of bleeding when taken with warfarin and should be
avoided. Clients should use a soft toothbrush to prevent gum bleeding, limit vitamin K-rich foods
(green leafy vegetables) to maintain consistent INR levels, and report signs of bleeding.
3. A nurse is assessing a client who is receiving digoxin. Which of the following findings should
indicate to the nurse that the client is experiencing digoxin toxicity?
A) Heart rate of 62/min
B) Yellow-green halos around lights
C) Blood pressure of 110/70 mm Hg
D) Weight gain of 1 kg in 24 hours
, Page 4 of 200
Answer: B
Visual disturbances, including yellow-green halos (xanthopsia), are classic signs of digoxin
toxicity. Other signs include nausea, vomiting, anorexia, and cardiac dysrhythmias (especially
bradycardia). A heart rate of 62/min may be within normal limits; hypotension and weight gain
are not specific to digoxin toxicity.
4. A nurse is preparing to administer a beta-blocker to a client who has hypertension. Which
of the following assessment findings should cause the nurse to withhold the medication?
A) Blood pressure 142/88 mm Hg
B) Apical pulse 52/min
C) Respiratory rate 18/min
D) Temperature 37.2°C (99°F)
Answer: B
Beta-blockers decrease heart rate and myocardial contractility. A pulse of 52/min is below the
