Q1 QUESTION 1 OF 100
A nurse is preparing to administer an intravenous medication to a patient requiring strict sterile precautions. To
minimize the risk of transmitting infection, which action should the nurse prioritize?
A) Ensure the patient's call light is within reach.
B) Perform thorough hand hygiene before donning sterile gloves.
C) Verify the medication order against the patient's wristband.
D) Cleanse the medication port with an alcohol swab.
CORRECT ANSWER
B) Perform thorough hand hygiene before donning sterile gloves.
RATIONALE
Performing hand hygiene before donning sterile gloves is the critical initial step in maintaining sterility and reducing
microbial transmission during invasive procedures, directly addressing the core principle of infection control. While other
options are important nursing actions, they do not directly supersede the initial step of hand hygiene for sterile technique.

, Q2 QUESTION 2 OF 100
A nurse is reviewing aseptic technique principles for a sterile procedure. The nurse recalls that breaking the chain of
infection is paramount. Which of the following represents the MOST critical intervention to interrupt the
transmission stage of the chain of infection?
A) Administering prophylactic antibiotics to the patient.
B) Performing thorough hand hygiene before and after patient contact.
C) Ensuring the patient's room is equipped with a HEPA filter.
D) Utilizing sterile gloves during all invasive procedures.
CORRECT ANSWER
B) Performing thorough hand hygiene before and after patient contact.
RATIONALE
Interrupting pathogen transmission via hands, a common vehicle, is crucial before and after contact with patients or
contaminated items, thereby breaking a primary link in the chain of infection. While sterile gloves and HEPA filters are
important, hand hygiene addresses the most frequent and often overlooked point of transmission.
Q3 QUESTION 3 OF 100
The nurse is preparing to administer a subcutaneous injection to a patient receiving chemotherapy for leukemia.
Before preparing the medication, the nurse meticulously washes their hands with soap and water for 20 seconds.
This action aligns with which principle of infection control?
A) Surgical asepsis to prevent introduction of microorganisms into the patient's sterile field.
B) Medical asepsis to reduce the number of microorganisms on the nurse's hands.
C) Standard precautions to prevent transmission of pathogens from the nurse to the patient.
D) Disinfection of the patient's skin prior to injection to eliminate all microbes.
CORRECT ANSWER
B) Medical asepsis to reduce the number of microorganisms on the nurse's hands.
RATIONALE
Washing hands with soap and water for 20 seconds is the cornerstone of medical asepsis, aimed at reducing the number of
microorganisms present on the skin, thereby minimizing the risk of transmission during patient care procedures. While
standard precautions are also employed, hand hygiene specifically addresses the reduction of microbial load on the hands.
Q4 QUESTION 4 OF 100
Page 2
,Which of the following best describes a condition in which a patient is free of all living microorganisms, including
spores?
A) Medical asepsis
B) Sterilization
C) Surgical asepsis
D) Disinfection
CORRECT ANSWER
C) Surgical asepsis
RATIONALE
Surgical asepsis, also known as sterility, ensures an environment completely free of pathogens and microorganisms, which is
critical for invasive procedures to prevent patient infection. Medical asepsis aims to reduce microorganisms but does not
guarantee their complete elimination.
Q5 QUESTION 5 OF 100
A 78-year-old patient admitted with pneumonia has a history of type 2 diabetes managed with metformin, a recent
hospitalization for a urinary tract infection treated with trimethoprim-sulfamethoxazole, and reports significant
stress due to family issues. The nurse is reviewing the patient's chart prior to administering prescribed antibiotics.
Which factor, based on the provided patient history, represents a significant risk factor for the development of a
new infection or worsening of existing infection?
A) The patient's age of 78 years
B) The prescribed antibiotic regimen
C) The reported family stress
D) The history of type 2 diabetes
CORRECT ANSWER
A) The patient's age of 78 years
RATIONALE
Advanced age is a well-established risk factor for infection due to potential declines in immune function and increased
susceptibility. While other factors like diabetes and prior antibiotic use are relevant, age itself is a primary, independent risk
factor for infection.
Q6 QUESTION 6 OF 100
The nurse is preparing to administer an intramuscular injection to a patient admitted with influenza. Considering
standard precautions, which of the following body fluids is the nurse MOST likely to anticipate as potentially
Page 3
, containing a transmissible infectious agent in this patient?
A) Sweat
B) Saliva
C) Urine
D) Tears
CORRECT ANSWER
B) Saliva
RATIONALE
Standard precautions dictate that all body fluids except sweat may contain transmissible infectious agents; therefore, saliva,
urine, and tears are all considered potentially infectious.
Q7 QUESTION 7 OF 100
A patient reports initial symptoms of a urinary tract infection (UTI) three days ago, for which they were prescribed an
antibiotic. Despite increasing fluid intake and consuming fruit juice, the patient admits to omitting the antibiotic
dose due to gastric upset. Today, the patient presents to the clinic experiencing fever, malaise, nausea, and
vomiting. What is the MOST likely interpretation of these current findings?
A) The patient is exhibiting a localized inflammatory response to the original UTI.
B) The patient has likely developed a systemic infection stemming from the untreated UTI.
C) The patient's symptoms are indicative of an acute allergic reaction to the antibiotic.
D) The patient is experiencing a viral gastroenteritis unrelated to the UTI.
CORRECT ANSWER
B) The patient has likely developed a systemic infection stemming from the untreated UTI.
RATIONALE
The patient's new systemic symptoms of fever, malaise, nausea, and vomiting, following a missed antibiotic course for a UTI,
suggest the infection has spread from the localized urinary tract to the bloodstream, causing sepsis.
Q8 QUESTION 8 OF 100
A nurse is preparing to perform a sterile procedure to insert a central venous catheter. To maintain the integrity of
the sterile field and prevent patient infection, the nurse must ensure which type of precautions are utilized
throughout the procedure?
A) Standard precautions for all patients
B) Droplet precautions due to potential respiratory secretions
