NR566 Week 3 Midterm Practice Test 2026 | Most Tested
Questions | Graded A+
1. When rx'ing Isotretinoin to a patient, what should you advise them to avoid to
decrease the risk of adverse effects associated with the medication?
anticoagulants
calcium
Vitamin A
prolonged sun exposure/UVL
2. Which of the following is an adverse effect of budesonide?
Urinary retention
Constipation
Blurry vision
Candidiasis
3. Describe how latanoprost affects eyelash characteristics and the implications
for patients using this medication.
Latanoprost only affects the color of eyelashes without changing their
length or thickness.
Latanoprost has no impact on eyelashes, and patients should not
expect any changes.
Latanoprost can enhance the length, thickness, and pigmentation of
eyelashes, which may be a desirable side effect for some patients.
Latanoprost causes eyelashes to fall out, which is a common side
effect.
,4. Discuss how monitoring side effects contributes to patient safety in
pharmacological treatments.
Monitoring side effects does not impact treatment outcomes.
Monitoring side effects helps in identifying adverse reactions early,
which is essential for maintaining patient safety.
Monitoring side effects is only necessary for high-risk patients.
Monitoring side effects is primarily for research purposes.
5. How do antihistamines treat allergies?
block the action of histamine at H1 receptors
bind to the allergen and block the reaction
block the action of histamine at H2 receptors
block the action of prostaglandin synthesis
6. Describe how the presence of comorbidities might influence the selection of
medications in a treatment plan.
The presence of comorbidities may require healthcare providers to
choose medications that minimize the risk of interactions and
consider the overall health of the patient.
Comorbidities have no impact on medication selection.
Comorbidities only affect the dosage of medications prescribed.
Comorbidities simplify the treatment process.
7. Which of the following are considerations for prescribing medications in the
pediatric population?
Whether the drug is safe and approved for use in children
, Appropriate dosing is based on the patient's age/weight/body surface
area
Discussing key information about adverse reactions with
child/parent/caregiver
A&C
All of the above
8. Describe the significance of understanding a drug's mechanism of action in
the context of pharmacological treatments.
Understanding a drug's mechanism of action helps healthcare
providers predict its effects and potential side effects.
Understanding a drug's mechanism of action is only important for
research purposes.
Understanding a drug's mechanism of action solely focuses on its
chemical composition.
Understanding a drug's mechanism of action is irrelevant to patient
care.
9. Describe the role of avobenzone in organic sunscreen formulations.
Avobenzone acts as a chemical filter that absorbs UV radiation,
providing effective protection against sun damage.
Avobenzone reflects UV rays away from the skin, preventing sunburn.
Avobenzone is a moisturizer that hydrates the skin while protecting
against UV rays.
Avobenzone is an antioxidant that neutralizes free radicals caused by
UV exposure.
, 10. What is the primary effect of glucocorticoids on allergic reactions?
They inhibit the release of histamine from mast cells.
They prevent the inflammatory response to allergens, thus
reducing all symptoms.
They increase the production of antibodies against allergens.
They enhance the immune response to allergens.
11. Describe how the activation of α1 receptors by sympathomimetics leads to a
reduction in nasal congestion.
Activation of α1 receptors increases mucus production, leading to
congestion relief.
Activation of α1 receptors enhances the immune response to
allergens.
Activation of α1 receptors relaxes the nasal passages, allowing for
easier airflow.
Activation of α1 receptors causes vasoconstriction, which reduces
blood flow to the nasal mucosa and decreases congestion.
12. What is the recommended antifungal treatment for otomycosis when initial
therapies fail?
Fluconazole
Ketoconazole
Nystatin
Clotrimazole (1% solution)
13. What is the primary role of guaifenesin in respiratory treatment?
