And Answers SNHU
Q1. Which laboratory measurement most directly reflects the
degree of cellular immune suppression in a patient with HIV?
A) Platelet count
B) CD4 helper T-lymphocyte count
C) Serum sodium
D) Hemoglobin A1c
Correct Answer: B) CD4 helper T-lymphocyte count
Rationale: CD4 lymphocytes are major targets of HIV, and progressive
depletion reflects worsening cellular immune impairment.
Q2. Which laboratory measurement is most useful for assessing the
effectiveness of antiretroviral therapy in suppressing HIV
replication?
A) Serum creatinine
B) Absolute neutrophil count
C) ESR
D) HIV viral load
Correct Answer: D) HIV viral load
Rationale: Effective antiretroviral therapy should suppress circulating HIV
RNA to very low or undetectable levels.
Q3. Which treatment principle is fundamental to modern HIV
pharmacotherapy?
A) Use an effective combination of antiretroviral agents from appropriate
drug classes.
B) Use single-drug therapy whenever possible.
C) Stop therapy when symptoms disappear.
D) Alternate treatment on and off every few weeks.
Correct Answer: A) Use an effective combination of antiretroviral agents from
appropriate drug classes.
Rationale: Combination therapy suppresses viral replication more
effectively and reduces the likelihood of resistance.
Q4. Which factor most strongly promotes development of
antiretroviral drug resistance?
A) Adequate hydration
B) Consistent medication timing
C) Repeated missed doses and incomplete viral suppression
D) Appropriate laboratory monitoring
, Correct Answer: C) Repeated missed doses and incomplete viral suppression
Rationale: Ongoing viral replication during inadequate drug exposure
creates selective pressure favoring resistant viral variants.
Q5. Which patient statement indicates appropriate understanding of
antiretroviral therapy?
A) “I can stop treatment when my viral load becomes undetectable.”
B) “I should take my medications consistently even when I feel well.”
C) “Missing several doses each week will not matter.”
D) “Treatment eliminates latent HIV from my body.”
Correct Answer: B) “I should take my medications consistently even when I
feel well.”
Rationale: Sustained adherence is necessary to maintain viral suppression
and reduce treatment failure and resistance.
Q6. Which medication characteristic should be reviewed carefully
before adding a new drug to an antiretroviral regimen?
A) Tablet color
B) Manufacturer location
C) Package size
D) CYP enzyme and transporter interaction potential
Correct Answer: D) CYP enzyme and transporter interaction potential
Rationale: Many antiretroviral medications inhibit or induce metabolic
enzymes and transporters, creating clinically significant interactions.
Q7. Which outcome most strongly demonstrates successful HIV
pharmacotherapy?
A) Durable viral suppression with preservation or recovery of immune
function
B) Elimination of all antibodies to HIV
C) Permanent discontinuation of follow-up
D) Increased viral load with stable symptoms
Correct Answer: A) Durable viral suppression with preservation or recovery of
immune function
Rationale: The major goals are sustained viral suppression, immune
preservation, prevention of complications, and reduction of transmission.
CHAPTER 2 — IMMUNOSUPPRESSANTS AND ORGAN TRANSPLANTATION
Q8. Why are immunosuppressive medications prescribed after solid-
organ transplantation?
A) To stimulate donor-reactive lymphocytes
