Sample questions from Cardiovascular Pharmacology

This material has 90 questions with answers and rationales. Here are the first 5.

1. 1.Which pharmacokinetic process describes movement of a medication from the bloodstream into body tissues?

   • A.Metabolism
   • B.Distribution
   • C.Absorption
   • D.Excretion

   Rationale: Distribution is the movement of a drug from the circulation into tissues and body fluids. Absorption moves a drug into the bloodstream, metabolism chemically changes it, and excretion removes it from the body. Protein binding and tissue perfusion can affect distribution.

2. 2.Refer to the client's chart. Which actions should the nurse take when administering the prescribed medication? Select all that apply.

   • A.Compare the medication with the medication administration record.
   • B.Verify the client's identity using two identifiers.
   • C.Check the allergy history before administration.
   • D.Document administration before giving the medication.
   • E.Ask the client to describe any prior reaction to the medication.

   Rationale: Two identifiers, allergy review, comparison with the medication administration record, and asking about prior reactions support safe administration. Documenting before administration is inappropriate because it can create a false record if the medication is not given. The chart notes a prior medication reaction, so clarification is especially important.

3. 3.A client with impaired renal function is prescribed a medication that is primarily excreted unchanged in the urine. Which effect is most likely if the dose is not adjusted?

   • A.Drug accumulation and toxicity
   • B.Increased first-pass metabolism
   • C.Reduced absorption
   • D.Faster onset of action

   Rationale: Reduced renal clearance can cause a renally excreted drug to accumulate, increasing toxicity risk. Impaired kidney function does not necessarily reduce absorption or increase first-pass metabolism. Faster onset is not an expected result of reduced excretion.

4. 4.At change of shift, a client receiving an IV medication reports new itching and develops generalized hives. What is the nurse's priority action?

   • A.Document the finding as an expected adverse effect.
   • B.Slow the infusion and reassess in 30 minutes.
   • C.Ask the client to take the next dose with food.
   • D.Stop the infusion and assess the client's airway and breathing.

5. 5.The provider prescribes 0.25 mg of a medication. The available tablets contain 0.125 mg each. How many tablets should the nurse administer?

   • A.0.5 tablet
   • B.4 tablets
   • C.2 tablets
   • D.1 tablet
