Guaranteed – A+ Graded
SECTION 1: Infection Control, Bloodborne Pathogens, & Safety
(Q1–Q15)
Q1: A nurse is preparing to administer medications to multiple patients on a
medical-surgical unit. After performing hand hygiene with an alcohol-based hand rub,
the nurse draws up medications for Patient A, then uses the same syringe to draw up
medications for Patient B to save time. What violation has occurred?
A. Failure to perform surgical hand scrub
B. Failure to use engineering controls
C. Never administering from the same syringe to multiple patients [CORRECT]
D. Failure to wear double gloves
Correct Answer: C
,Rationale: A fundamental work practice control in infection prevention is never
administering medications from the same syringe to multiple patients, as this creates a
direct cross-contamination risk. Option A is incorrect because surgical hand scrub is not
required for routine medication administration. Option B refers to safety devices like
needleless systems, not syringe reuse. Option D is incorrect as double gloves are not
standard for medication administration. [100% VERIFIED – HealthStream 2026/2027]
Q2: A phlebotomist sustains a needlestick injury while drawing blood from a patient
known to be HIV-positive. What is the FIRST action the phlebotomist should take?
A. Immediately begin post-exposure prophylaxis medication
B. Wash the exposed area with soap and water and report according to protocol
[CORRECT]
C. Wait for laboratory confirmation before taking any action
D. Apply a tourniquet proximal to the injury site
Correct Answer: B
Rationale: The immediate first step after a bloodborne pathogen exposure is to wash
the exposed area with soap and water and report according to institutional protocol.
Option A is incorrect because PEP should not begin before risk assessment and
protocol guidance. Option C delays critical intervention. Option D is inappropriate for a
,needlestick injury and could cause further harm. [100% VERIFIED – HealthStream

Q3: A healthcare worker sustains a needlestick exposure to blood from a patient with
unknown HIV status. According to CDC guidelines and HealthStream competency
standards, within what timeframe should HIV post-exposure prophylaxis ideally be
initiated?
A. Within 72 hours
B. Within 48 hours
C. Within hours [CORRECT]
D. Within 1 week
Correct Answer: C
Rationale: HIV post-exposure prophylaxis should begin within hours of exposure to
maximize effectiveness, with earlier initiation being more protective. Option A (72
hours) is the outer limit but not the ideal timeframe. Option B is better than A but still
not as urgent as "within hours." Option D is far beyond the acceptable window and
would render PEP ineffective. [100% VERIFIED – HealthStream 2026/2027]
, Q4: A nursing student sustains a splash exposure to blood while caring for a patient
with chronic hepatitis B. The student has not previously received the hepatitis B vaccine.
According to OSHA standards and HealthStream protocols, what is the required timeline
for initiating hepatitis B post-exposure prophylaxis?
A. Within 1 week
B. Within 24 hours [CORRECT]
C. Within 48 hours
D. Within 72 hours
Correct Answer: B
Rationale: Hepatitis B post-exposure prophylaxis, including hepatitis B immune globulin
(HBIG) and initiation of the vaccine series, should begin within 24 hours of exposure.
Option A is too delayed. Options C and D exceed the recommended timeframe and
reduce the effectiveness of prophylaxis. [100% VERIFIED – HealthStream 2026/2027]
Q5: A hospital is evaluating new safety devices to reduce needlestick injuries among
nursing staff. They are considering retractable needles, needleless IV systems, and
safety scalpels. What category of bloodborne pathogen controls do these devices
represent?
A. Work practice controls
