NR 565 Exam 3: Advanced Pharmacology Fundamentals V4
Updated and Latest Questions and Correct Answers with
Rationale
1. A patient is prescribed Fluoxetine for depression. Which statement by the patient
indicates a need for further teaching?
A. I will take this medication in the morning.
B. It may take 4 to 6 weeks to feel the full effect.
C. I should stop taking this immediately if I feel better.
D. I need to watch for increased suicidal thoughts.
Ans: C
Rationale: Selective serotonin reuptake inhibitors should never be stopped abruptly without medical
supervision. Stopping the medication suddenly can lead to discontinuation syndrome characterized by
flu-like symptoms. Patients must be educated that therapeutic effects take several weeks to manifest.
Education should also include the timing of doses to avoid insomnia. Monitoring for mood changes and
suicidal ideation is a critical safety component. Adherence to the prescribed regimen is essential for long-
term management of depression.
,2. Which laboratory value is most critical to monitor for a patient taking Lithium?
A. Liver enzymes
B. Serum sodium level
C. Blood glucose
D. Serum calcium
Ans: B
Rationale: Lithium has a narrow therapeutic index and is handled by the kidneys like sodium. When
sodium levels are low, the kidneys retain lithium, potentially leading to toxicity. Patients should maintain
a consistent intake of salt and fluids while on this therapy. Dehydration or excessive sweating can also
lead to dangerously high levels of the drug. Regular blood draws are required to ensure the lithium level
stays within the safe range. Any significant change in diet or hydration status requires immediate
notification of the provider.
3. A patient is starting Metformin for Type 2 Diabetes. What is the most common side effect
the NP should discuss?
A. Weight gain
B. Hypoglycemia
C. Gastrointestinal distress
D. Fluid retention
Ans: C
,Rationale: Metformin frequently causes side effects such as nausea, diarrhea, and abdominal bloating.
These symptoms are usually dose-related and often subside over time as the body adjusts. Taking the
medication with meals can help minimize these unpleasant gastrointestinal effects. Unlike sulfonylureas,
metformin does not typically cause hypoglycemia when used as monotherapy. It is considered a first-line
treatment due to its efficacy and weight-neutral profile. Monitoring renal function is vital because of the
risk of lactic acidosis.
4. Levothyroxine is prescribed for a patient with hypothyroidism. When should they be
instructed to take it?
A. With a large evening meal
B. In the morning, 30-60 minutes before breakfast
C. Right before going to bed at night
D. With their morning coffee or calcium supplement
Ans: B
Rationale: Levothyroxine absorption is significantly affected by the presence of food and certain
minerals. Taking it on an empty stomach in the morning ensures consistent and maximum absorption.
Patients should avoid taking calcium, iron, or antacids within four hours of their dose. Consistency in
administration is the key to maintaining stable thyroid-stimulating hormone levels. If the patient misses a
dose, they should take it as soon as possible. Thyroid levels are typically checked 6 to 8 weeks after
starting therapy.
, 5. A patient on a Monoamine Oxidase Inhibitor (MAOI) must avoid which of the following
foods?
A. Aged cheeses and cured meats
B. Fresh chicken and rice
C. Fresh apples and oranges
D. Boiled eggs and toast
Ans: A
Rationale: MAOIs prevent the breakdown of tyramine, an amino acid found in various aged or fermented
foods. High levels of tyramine can trigger a massive release of norepinephrine, causing a hypertensive
crisis. Symptoms of this crisis include severe headache, palpitations, and neck stiffness. Patients must be
strictly educated on dietary restrictions to prevent this life-threatening event. This restriction applies for
at least two weeks after stopping the medication as well. Many over-the-counter cold medications are
also contraindicated with MAOI therapy.
6. What is the primary mechanism of action for Second-Generation Antipsychotics (SGAs)?
A. Pure dopamine D2 receptor blockade
B. Dopamine D2 and Serotonin 5-HT2A receptor blockade
C. GABA receptor agonism
D. Norepinephrine reuptake inhibition
Ans: B
