CHAPTER 1: DISEASE PREVENTION & HEALTH PROMOTION



QUESTION 1

Which of the following behaviors indicates the highest potential for spreading
infections among clients?



A) Disinfecting dirty hands with antibacterial soap


1

,B) Allowing alcohol-based rub to dry for 10 seconds

C) Washing hands only after leaving each room

D) Using cold water for medical asepsis



Correct Answer: C
Explanation: The most frequent cause of infection spread among institutionalized
patients is the hands of healthcare workers. Hand washing must be performed
before and after all contact with patients. Washing only after leaving the room fails
to prevent transmission between patients [citation:1][citation:2].



QUESTION 2

What is the most frequent cause of the spread of infection among institutionalized
patients?



A) Airborne microbes from other patients

B) Contact with contaminated equipment

C) Hands of healthcare workers

D) Exposure from family members



Correct Answer: C
Explanation: Healthcare workers' hands are the primary vehicle for transmitting
infections in healthcare settings. Hand hygiene interrupts transmission and should
be performed before and after all patient contact [citation:1][citation:2].

,QUESTION 3

A patient infected with a virus but who does not have any outward sign of the
disease is considered a:



A) Pathogen

B) Fomite

C) Vector

D) Carrier



Correct Answer: D
Explanation: A carrier is an individual who harbors an infectious organism without
displaying symptoms but can transmit the infection to others. A pathogen is the
disease-causing microorganism; a fomite is an inanimate object that carries
pathogens; a vector is a living organism that transmits infection
[citation:1][citation:8].



QUESTION 4

A patient is admitted to the hospital with tuberculosis. Which precautions must the
nurse institute when caring for this patient?



A) Droplet transmission

B) Airborne transmission

C) Direct contact

D) Indirect contact



3

, Correct Answer: B
Explanation: Tuberculosis requires airborne precautions because the organism is
transmitted via small-particle aerosols that remain suspended in the air. This
requires an N-95 respirator mask and negative-pressure isolation [citation:1].



QUESTION 5

A patient becomes infected with oral candidiasis (thrush) while receiving
intravenous antibiotics to treat a systemic infection. Which type of infection has
the patient developed?



A) Endogenous nosocomial

B) Exogenous nosocomial

C) Latent

D) Primary



Correct Answer: A
Explanation: Endogenous nosocomial infections originate from the patient's own
microbial flora that become pathogenic due to factors like antibiotic therapy
disrupting normal flora. Candidiasis following antibiotic use is a classic example
[citation:1].



QUESTION 6

A patient admitted to the hospital with pneumonia has been receiving antibiotics
for 2 days. His condition has stabilized, and his temperature has returned to
normal. Which stage of infection is the patient most likely experiencing?
