6521 ADVANCED PHARMACOLOGY FINAL WITH ACTUAL
QUESTIONS AND CORRECT ANSWERS AND RATIONALES
NEW UPDATE
This document is a comprehensive collection of NCLEX-style multiple-choice
questions and answers for nursing students and professionals. It covers a wide
range of pharmacological topics, including medications for psychiatric disorders
(MAOIs, lithium, antipsychotics), neurological conditions, infectious diseases
(antibiotics, antifungals, antivirals), cardiovascular issues (anticoagulants), and
drugs for special populations (pediatrics, geriatrics, pregnancy). Each question
includes a detailed rationale explaining the correct answer and why the distractors
are incorrect. The content emphasizes critical thinking, drug mechanisms, side
effects, drug interactions, and patient teaching. It serves as an excellent study guide
for exam preparation.
**A patient taking an MAOI is seen in the clinic with a blood pressure of 170/96
mm Hg. What will the nurse ask this patient?**
- A) "Have you been taking your medication as prescribed?"
- B) "When did you last have your blood pressure checked?"
- C) "To list all foods eaten that day"
- D) "Are you experiencing any chest pain or shortness of breath?"
**Answer: C**
**Rationale:** MAOIs can cause a hypertensive crisis when combined with foods
high in tyramine (e.g., aged cheeses, cured meats, fermented products). A sudden
rise in blood pressure is a key sign, and the nurse must first assess for dietary
triggers.
,**A patient taking fluoxetine [Prozac] complains of decreased sexual interest. A
prescriber orders a "drug holiday." What teaching by the nurse would best describe
a drug holiday?**
- A) "Stop taking the medication for a month to see if your sexual interest
returns."
- B) "Don't take the medication on Friday and Saturday."
- C) "Take a double dose on Monday to skip the rest of the week."
- D) "Reduce your dose by half every day for two weeks."
**Answer: B**
**Rationale:** A "drug holiday" for SSRI-induced sexual dysfunction typically
involves omitting the dose for 1-2 days (often over a weekend) to allow drug levels
to drop and reduce side effects, while minimizing withdrawal symptoms due to
fluoxetine's long half-life.
**A patient with bipolar disorder who wants to minimize the need for drug therapy
asks the nurse what else can be done to treat the disorder. The nurse will
recommend which measures? Select all that apply.**
- A) Psychotherapy
- B) High-dose vitamin supplements
- C) Regular sleep and exercise
- D) A high-carbohydrate diet
- E) Using a chart to monitor mood changes
**Answers: A, C, E**
**Rationale:** Adjunctive measures for bipolar disorder include psychotherapy
(to improve coping and adherence), maintaining regular sleep and exercise (to
stabilize mood rhythms), and mood charting (to identify triggers and early signs of
episodes). Vitamin supplements and specific diets are not standard evidence-based
recommendations.
**A patient with bipolar disorder who is taking divalproex sodium [Valproate] has
just been admitted to the hospital. During the admission assessment, the patient
tells the nurse about recent suicidal ideation. The nurse observes several areas of
bruising over soft tissue areas and notes a weight gain of 10 pounds since the last
admission 1 year ago. What will the nurse do?**
,- A) Document the findings as expected side effects of divalproex.
- B) Reassure the patient that these symptoms will resolve over time.
- C) Contact the provider to report these findings.
- D) Increase the patient's dose of divalproex.
**Answer: C**
**Rationale:** Bruising can indicate thrombocytopenia (a serious adverse effect of
valproate), and suicidal ideation requires immediate intervention. Weight gain is
common but less urgent. The provider must be notified to assess lab values
(platelet count) and address the psychiatric emergency.
**A patient with bipolar disorder takes lamotrigine [Lamictal]. Which statement
by the patient would prompt the nurse to hold the drug and notify the prescriber for
further assessment?**
- A) "I've been feeling a little dizzy when I stand up quickly."
- B) "I've broken out in a rash on my chest and back."
- C) "I've gained about 3 pounds since starting the medicine."
- D) "I have a mild headache that comes and goes."
**Answer: B**
**Rationale:** Lamotrigine carries a black box warning for serious rashes,
including Stevens-Johnson syndrome. Any rash, especially one that is widespread,
requires immediate discontinuation and provider notification to rule out a life-
threatening reaction.
**A patient who has recently begun taking carbamazepine [Equetro] for bipolar
disorder reports having vertigo and headaches. Which action by the nurse is
appropriate?**
- A) Withhold the medication and notify the prescriber.
- B) Request an order for a serum carbamazepine level.
- C) Reassure the patient that these effects occur early in treatment and will
resolve over time.
- D) Suggest the patient take the medication with a high-fat meal.
**Answer: C**
, **Rationale:** Dizziness, vertigo, and headache are common dose-related side
effects that often occur early in carbamazepine therapy and typically subside as
tolerance develops. No immediate intervention is needed unless symptoms are
severe or persistent.
**A patient is admitted to a hospital for treatment for first-time symptoms of
mania and is exhibiting euphoric mania. Which medication will the provider
order?**
- A) Fluoxetine [Prozac]
- B) Carbamazepine [Equetro]
- C) Lithium [Lithobid]
- D) Lamotrigine [Lamictal]
**Answer: C**
**Rationale:** Lithium is the first-line agent for acute euphoric mania and has
been the gold standard for decades. Other mood stabilizers (e.g., valproate,
carbamazepine) are also used, but lithium is particularly effective for classic,
euphoric mania.
**A patient with bipolar disorder has been taking lithium [Lithobid] for several
years. The patient has developed a goiter, and serum tests reveal hypothyroidism.
What will the nurse expect the provider to order for this patient?**
- A) Discontinuation of lithium
- B) Administration of levothyroxine
- C) A low-iodine diet
- D) An increased dose of lithium
**Answer: B**
**Rationale:** Lithium inhibits thyroid hormone release, often causing
hypothyroidism and goiter. The standard approach is to continue lithium (if mood-
stabilizing) and add levothyroxine to restore euthyroid state.
**A nurse is preparing to administer medications to a hospitalized patient who has
been taking lithium [Lithobid] for 3 days. The patient is complaining of mild
