Q&A
1. A 48-year-old patient with a history of heavy menstrual bleeding presents with fatigue,
pallor, and dyspnea on exertion. Laboratory results reveal a hemoglobin of 8.2 g/dL,
mean corpuscular volume (MCV) of 72 fL, and low serum ferritin. What is the most likely
type of anemia?
A) Anemia of chronic disease
B) Sideroblastic anemia
C) Iron-deficiency anemia
D) Thalassemia
Correct Answer: C) Iron-deficiency anemia
Rationale: Iron-deficiency anemia is the most common cause of microcytic anemia and is
characterized by low hemoglobin, low MCV, and low ferritin. Heavy menstrual bleeding is
a classic cause of iron loss. Anemia of chronic disease is typically normocytic, sideroblastic
anemia is rare, and thalassemia is genetic.
2. A hospice nurse is caring for a patient who has just been diagnosed with a terminal
illness. The patient states, "I don't believe this is happening to me. There must be a
mistake." According to Kübler-Ross, which stage of grief is the patient exhibiting?
A) Anger
B) Depression
C) Denial
D) Bargaining
Correct Answer: C) Denial
,Rationale: According to Kübler-Ross, the stages of grief occur in the following order:
Denial, Anger, Bargaining, Depression, and Acceptance. Denial is the initial stage,
characterized by disbelief and shock. Anger follows, then bargaining, depression, and
finally acceptance.
3. A 32-year-old patient with a newly diagnosed HIV infection asks the nurse about the
primary goal of treatment. What is the most accurate response regarding the current goal
of antiretroviral therapy (ART)?
A) Complete eradication of the virus from the body
B) Viral suppression to undetectable levels in the peripheral blood
C) Preventing all opportunistic infections
D) Maintaining a CD4 count above 200 cells/mm³
Correct Answer: B) Viral suppression to undetectable levels in the peripheral blood
Rationale: The current goal of ART is to achieve and maintain an undetectable viral load.
While maintaining CD4 count and preventing opportunistic infections are important, they
are secondary to viral suppression, and complete eradication is not currently possible.
4. The effectiveness of benzodiazepines in treating anxiety disorders suggests that which
neurotransmitter plays a significant role in anxiety?
A) Acetylcholine
B) Dopamine
C) Serotonin
D) Gamma-aminobutyric acid (GABA)
Correct Answer: D) Gamma-aminobutyric acid (GABA)
, Rationale: Benzodiazepines enhance the effects of GABA, the primary inhibitory
neurotransmitter in the central nervous system. This suggests that GABA plays a
significant role in anxiety. Other neurotransmitters like serotonin and dopamine are also
involved but are not the primary target of benzodiazepines.
5. A patient who has been taking fluoxetine for major depressive disorder is being
switched to a monoamine oxidase inhibitor (MAOI). How long should the patient wait
after discontinuing fluoxetine before starting the MAOI?
A) 2 weeks
B) 3 weeks
C) 4 weeks
D) 5 weeks
Correct Answer: D) 5 weeks
Rationale: Fluoxetine has a long half-life and its active metabolite, norfluoxetine, can
remain in the body for several weeks. A washout period of at least 5 weeks is
recommended before starting an MAOI to avoid the risk of serotonin syndrome.
6. A 55-year-old female presents with complaints of dry eyes, a gritty sensation, and
blurred vision. The clinician suspects keratoconjunctivitis sicca. Which of the following is a
classic sign of this condition?
A) Hypercholesterolemia
B) Decreased TRH
C) Elevated cortisol
D) Hyperthyroidism
Correct Answer: A) Hypercholesterolemia
