NURS 6521 Advanced Pharmacology Exam 1 Questions &
Answers 2026 | High-Yield Review | Graded A+
1. Describe the differences between the quickest and slowest routes of drug
absorption.
The quickest route is intravenous (IV), which delivers drugs directly
into the bloodstream, while the slowest route is oral, where drugs
must pass through the digestive system before entering circulation.
The quickest route is subcutaneous, which is absorbed through the
skin, while the slowest route is intramuscular, which takes longer to
enter the bloodstream.
The quickest route is oral, which is absorbed through the stomach,
while the slowest route is intravenous (IV), which takes time to
circulate.
The quickest route is intramuscular, which is injected into muscle, while
the slowest route is subcutaneous, which is injected into fat.
2. If a patient is taking multiple medications that are highly protein bound, what
potential issue should a nurse practitioner monitor for?
Increased risk of drug interactions and altered drug efficacy.
Decreased absorption of the medications.
Enhanced therapeutic effects of all medications.
Reduced side effects from the medications.
3. Describe how low albumin levels in elderly patients can influence drug
therapy outcomes.
Low albumin levels can lead to increased free drug concentrations,
enhancing the risk of toxicity.
, Low albumin levels improve drug efficacy.
Low albumin levels decrease drug absorption in the gastrointestinal
tract.
Low albumin levels have no significant impact on drug therapy.
4. If a nurse practitioner prescribes a weak acid medication to a patient with a
condition that increases gastric pH, what potential impact could this have on
the drug's absorption?
No impact on absorption
Decreased absorption
Absorption only in the small intestine
Increased absorption
5. Describe how blood flow affects the distribution of drugs in the body.
Blood flow has no significant impact on drug distribution.
Blood flow is only relevant for intravenous drug administration.
Blood flow affects drug distribution by determining how quickly and
efficiently a drug reaches various tissues.
Blood flow only affects the absorption of drugs, not their distribution.
6. What is the definition of protein binding in pharmacology?
It indicates the rate at which drugs are metabolized by the liver.
It describes the process of drug absorption in the gastrointestinal
tract.
It refers to the degree to which drugs attach to proteins in the
blood.
, It signifies the elimination of drugs from the body.
7. If a patient presents with a blood pH of 7.25, what potential health issue might
they be experiencing?
Acidosis
Dehydration
Hyperglycemia
Alkalosis
8. What are the four categories of pharmacokinetics?
Administration, distribution, metabolism, elimination
Absorption, synthesis, metabolism, elimination
Distribution, metabolism, excretion, interaction
Absorption, distribution, metabolism, excretion
9. Describe the significance of pharmacokinetics in drug therapy.
Pharmacokinetics outlines the legal requirements for drug prescribing.
Pharmacokinetics focuses solely on the side effects of drugs.
Pharmacokinetics is only concerned with drug interactions.
Pharmacokinetics helps determine how a drug is absorbed,
distributed, metabolized, and excreted, which is crucial for effective
and safe medication use.
10. What is the primary concern when two drugs compete for protein-binding
sites in the body?
Altered efficacy of both drugs
, Increased risk of allergic reactions
No significant interaction
Enhanced drug absorption
11. Describe the significance of selecting a narrow-spectrum antibiotic for
treating gram-positive cocci infections.
Narrow-spectrum antibiotics are only effective in the gastrointestinal
tract.
Narrow-spectrum antibiotics target specific bacteria, reducing the
risk of disrupting normal flora and minimizing antibiotic resistance.
Narrow-spectrum antibiotics are less effective than broad-spectrum
antibiotics.
Narrow-spectrum antibiotics can be used for any type of infection.
12. Bactrim is a combination drug that:
C. inhibits bacterial topoisomerase and DNA gyrase
A. contains suffomethoxazole and inhibits bacterial folate
metabolism
D. is a combination of amoxicillin and clavulanic acid
B. inhibits bacterial cell wall synthsis and Beta-lactamase
E. both B and D
13. Describe the significance of a drug being a substrate for an enzyme in
pharmacology.
If a drug is a substrate for an enzyme, it indicates that the drug will
not interact with other medications.
