NR 565 ADVANCED PHARMACOLOGY:
FUNDAMENTALS MIDTERM EXAM REVIEW
| Week 4 Midterm | Exemplify Online Proctored
The NR 565 Advanced Pharmacology Midterm Review is a
comprehensive 800-question exam covering
pharmacokinetics, major drug classes, and lifespan
considerations, designed to test clinical application and
safe prescribing. It emphasizes critical thinking and
NCLEX-aligned rationales to ensure mastery of advanced
pharmacotherapeutics for the proctored midterm.
,Question 1
A patient on long-term prednisone therapy is prescribed oral calcium supplements. What
potential interaction should the nurse practitioner be aware of?
A. Increased calcium absorption
B. Reduced calcium absorption
C. Enhanced prednisone effects
D. Decreased prednisone effects
Rationale: Long-term prednisone therapy impairs intestinal calcium absorption through
diminished expression of active calcium transport proteins in the duodenum, particularly TRPV6
and calbindin-D9K. All corticosteroids also increase renal calcium excretion, leading to a
negative calcium balance and increased risk of osteoporosis. This means that even when calcium
supplements are taken, the actual amount absorbed into the bloodstream may be significantly
reduced. The NP should be aware that patients on long-term prednisone may require vitamin D
supplementation, higher calcium doses, and bone mineral density monitoring to prevent
corticosteroid-induced bone loss.

Question 2
The NP is deciding between two oral formulations of the same medication. One is a rapidly
dissolving tablet and the other is an enteric-coated form. Which factor is probably responsible
for the faster onset of action of the rapid dissolving tablet?
A. Faster blood flow in the liver compared to peripheral tissues
B. Increased lipid solubility in enteric-coated design
C. Faster rate of dissolution leading to quicker absorption
D. Larger surface area of the stomach compared to the intestine
Rationale: Dissolution is the rate-limiting step for the absorption of most oral solid dosage
forms. Rapidly dissolving tablets disintegrate and dissolve quickly in the gastrointestinal fluids,
allowing the drug to be absorbed into the systemic circulation faster. Enteric-coated
formulations are designed to resist dissolution in the acidic environment of the stomach and
only dissolve in the more alkaline environment of the intestines, which intentionally delays the
onset of action to protect the stomach lining or the drug itself. Therefore, the faster rate of
dissolution directly correlates with a quicker onset of action.

,Question 3
A 65-year-old patient with a history of osteoporosis is prescribed long-term corticosteroid
therapy. Which adjunct medication should the NP anticipate adding to the treatment plan?
A. Potassium supplements
B. Vitamin D and bisphosphonates
C. Sodium supplements
D. Calcium channel blockers
Rationale: Long-term corticosteroid therapy significantly increases the risk of osteoporosis by
decreasing intestinal calcium absorption and increasing renal calcium excretion. Therefore,
Vitamin D supplementation is crucial to facilitate calcium absorption, and bisphosphonates are
often prescribed to inhibit osteoclast-mediated bone resorption and prevent bone loss.
Potassium, sodium, and calcium channel blockers do not address the underlying
pathophysiology of corticosteroid-induced bone loss.

Question 4
Which pharmacokinetic principle explains why a drug with high lipid solubility will cross the
blood-brain barrier faster than a water-soluble drug?
A. High lipid solubility increases renal clearance.
B. The blood-brain barrier is composed of a lipid bilayer.
C. Water-soluble drugs have a higher volume of distribution.
D. High lipid solubility decreases first-pass metabolism.
Rationale: The blood-brain barrier is formed by tight junctions of capillary endothelial cells
surrounded by a lipid-rich environment. Drugs that are highly lipid-soluble can easily diffuse
through this lipid bilayer to reach the central nervous system. Conversely, water-soluble drugs
penetrate the blood-brain barrier poorly. Renal clearance and volume of distribution are related
to elimination and tissue binding, not specifically the mechanism of crossing the blood-brain
barrier.

Question 5
A patient is prescribed levothyroxine. The NP should instruct the patient to take this medication
at which time to maximize absorption?
A. With breakfast
, B. On an empty stomach, 30-60 minutes before breakfast
C. At bedtime with a snack
D. With calcium supplements
Rationale: Levothyroxine absorption is highly variable and is affected by food, especially dietary
fiber, and supplements like calcium and iron. Taking it on an empty stomach 30 to 60 minutes
before breakfast ensures maximum and consistent absorption. Taking it with food or
supplements significantly decreases its bioavailability, potentially leading to subtherapeutic
levels and uncontrolled hypothyroidism.

Question 6
Which class of medications is most associated with a dry, persistent cough as a common adverse
effect?
A. Angiotensin II receptor blockers (ARBs)
B. Angiotensin-converting enzyme (ACE) inhibitors
C. Beta-blockers
D. Calcium channel blockers
Rationale: ACE inhibitors block the conversion of angiotensin I to angiotensin II, but they also
inhibit the breakdown of bradykinin. The accumulation of bradykinin in the lungs is responsible
for the dry, persistent cough experienced by approximately 10-20% of patients on ACE inhibitors.
ARBs do not affect bradykinin levels and are often used as a substitute for patients who cannot
tolerate the cough. Beta-blockers can cause bronchospasm, and calcium channel blockers can
cause peripheral edema, but not typically a dry cough.

Question 7
A patient with type 2 diabetes is prescribed metformin. Which laboratory value should the NP
monitor closely due to the risk of a rare but severe adverse effect?
A. Serum potassium
B. Serum creatinine and renal function
C. Serum calcium
D. Liver function tests
