1. A nursing student is caring for a patient who has been taking morphine sulfate
for pain for 2 weeks. What statement by the nursing student shows an
understanding of pharmacodynamic tolerance?
"An increase in responsiveness to morphine results from repeated
dosing over a short period."
"This response to morphine is caused by psychological factors and not
by biochemical or physiological properties."
"The patient requires increased doses of morphine to achieve pain
relief."
"The minimum effective concentration of morphine is lowered."
2. A nurse is administering a new medication to a patient. How should the nurse
apply their knowledge of pharmacodynamics in this situation?
By administering the medication without any follow-up.
By disregarding the patient's medical history.
By monitoring the patient's response to the medication and
adjusting the care plan as needed.
By only focusing on the medication's side effects.
3. The nurse is caring for a patient with acute renal failure. The nurse should
carefully assess for what?
Increased drug excretion
Increased tolerance to the medication
Decreased drug levels in the blood
, Accumulation of drugs in the body
4. Describe the primary purpose of the Controlled Substances Act in relation to
drug regulation.
The Controlled Substances Act aims to regulate the manufacture
and distribution of drugs that have the potential for abuse to
prevent misuse and protect public health.
The Controlled Substances Act focuses solely on the approval of new
medications for market release.
The Controlled Substances Act is designed to promote the use of
over-the-counter medications.
The Controlled Substances Act only addresses the safety of herbal
supplements.
5. Why is patient adherence considered essential in achieving the therapeutic
objectives of medications?
Patient adherence does not impact the effectiveness of medications.
Patient adherence is only important for chronic conditions.
Patient adherence is only relevant for nonpharmacologic measures.
Patient adherence ensures that medications are taken as prescribed,
which is crucial for their effectiveness.
6. What is one key reason why ease of administration is important for drugs?
It enhances patient compliance.
It minimizes side effects.
It increases drug potency.
It reduces drug interactions.
,7. A nurse is educating a patient about their medication regimen. Which strategy
should the nurse emphasize to enhance the patient's adherence to the
therapy?
Reassuring the patient that all medications are completely free of side
effects.
Telling the patient that adherence is not important for their treatment.
Incorporating nonpharmacologic measures alongside medication.
Encouraging the patient to skip doses if they feel better.
8. Which statement by a new nurse indicates that further study is indicated?
Drugs are defined as illegal substances.
There is no such thing as a selective drug; all medications cause side
effects.
Effectiveness is the most important property a drug can have.
There is no such thing as a safe drug.
9. Describe the role of dobutamine as an agonist in the context of
pharmacology.
Dobutamine inhibits norepinephrine receptors, decreasing heart
contractility.
Dobutamine acts as an agonist of norepinephrine receptors,
increasing heart contractility and heart rate.
Dobutamine acts as an antagonist of serotonin receptors, reducing
anxiety.
Dobutamine has no significant effect on heart function.
, 10. The nurse is obtaining a drug history for a patient admitted to the unit. The
nurse obtains information about past and present health histories, currently
used prescription drugs, behavioral factors, and use of over-the-counter
drugs. Which additional information does the nurse need to obtain?

12. What is the term for the effect that occurs when nitroglycerine and alcohol
are taken together, leading to a drop in blood pressure?
Drug interaction
Adverse effect
Pharmacodynamics
Pharmacokinetics
13. What is the primary goal of drug therapy as identified by nurses in patient
treatment?
To focus solely on patient education.
