Total questions: 40
Worksheet time: 20mins
Isolation in healthcare is primarily used to:
Provide privacy to the patient
Prevent or reduce the transmission of infectious agents
Restrict patient mobility only
Reduce hospital costs
One of the main purposes of isolation is to:
Protect hospital staff only
Ensure patients stay in bed rest
Protect vulnerable patients from pathogens
Replace antibiotic therapy
Which of the following is NOT a reason for placing a patient in isolation?
Preventing the spread of pathogens
Protecting immunocompromised patients
Increasing the length of hospital stay
Reducing risk of hospital-acquired infections
Protecting a very susceptible patient from exposure to pathogens is an example of:
Source isolation
Reverse isolation
Contact precaution
Droplet precaution
Which component of the infection cycle is most directly targeted by isolation?
Susceptible host
Portal of entry
Mode of transmission
Pathogen virulence
If the chain of infection is interrupted at the "portal of exit," the nurse should:
Use protective immunizations
Provide hand hygiene and covering of wounds
Increase patient nutrition
Administer broad-spectrum antibiotics
A nurse placing a mask on a patient with TB is breaking the chain at the level of:
Reservoir
Portal of entry
Portal of exit
Susceptible host
Reverse isolation is designed to protect:
Nurses from infected patients
Visitors from nosocomial infection
Immunocompromised patients
Patients with highly contagious disease
Which condition would most likely require reverse isolation?
Pulmonary tuberculosis
Hepatitis B
Leukemia under chemotherapy
MRSA wound infection
Before admitting a patient under reverse isolation, the nurse should ensure:
The room is disinfected thoroughly
All windows remain open
Patient remains in negative pressure room
No protective equipment is used
In reverse isolation, staff entering the room must wear:
Only gloves
Sterile gowns and masks
Apron without gloves
Shoe covers only
Source isolation is primarily intended to:
Limit spread of pathogens from infected patient
Protect immunocompromised patients
Reduce hospital cleaning costs
Enhance medication effectiveness
Determination of isolation procedure in source isolation depends on all EXCEPT:
Mode of transmission
Location of pathogen
Patient’s economic status
Virulence and susceptibility of pathogen
Contact precautions are mainly used for pathogens transmitted by:
Airborne particles
Direct and indirect touch
Large droplets
Vector-borne insects
A patient with Clostridium difficile should be placed under:
Airborne precautions
Droplet precautions
Contact precautions
Reverse isolation
Droplet precautions are required for:
Tuberculosis
Measles
Influenza
Chickenpox
Which PPE is mandatory when caring for a patient on droplet precautions?
N95 mask
Surgical mask
Sterile gown
Face shield only
Airborne precautions should be instituted for:
MRSA wound infection
Pertussis
Pulmonary tuberculosis
Hepatitis A
The type of room required for airborne precautions is:
Positive pressure room
Negative pressure room
Single bed only
Shared ward with curtains
Which sign should be placed outside the room of a patient under strict isolation?
"Visitors Welcome"
"No Food Inside"
"Infection Control Precautions – See Nurse Before Entry"
"Private Room" only
A nurse’s first responsibility when entering an isolation room is:
Provide medication
Perform hand hygiene
Adjust patient’s bed
Check vital signs
Which is a correct principle of gown use in isolation?
Gown may be reused if not visibly soiled
Gown should be removed before leaving the room
Gown must be worn outside the room
No gown required if gloves are used
When removing PPE after isolation care, the first item to be removed is:
Gloves
Mask
Gown
Cap
When transporting a patient on airborne precautions, the nurse should ensure:
Patient wears a surgical mask
No protective equipment is required
Patient remains in wheelchair without mask
Staff wears N95, patient unprotected
Which nursing action helps prevent psychological effects of isolation?
Limit patient contact
Provide health teaching and emotional support
Reduce nurse-patient communication
Keep patient uninformed
A patient with neutropenia after chemotherapy develops a fever. Which isolation is appropriate?
Source isolation
Reverse isolation
Contact precautions
Droplet precautions
If a patient is placed on source isolation for MRSA, which measure is most important?
Use sterile gloves only
Use PPE according to contact transmission precautions
Ensure patient receives vitamin supplements
Restrict visitors completely
Which combination of precautions is correct for a patient with chickenpox?
Contact + Droplet
Airborne + Contact
Reverse isolation
Standard precautions only
Which infection requires strict isolation due to multiple transmission routes (airborne and contact)?
Hepatitis B
Varicella (chickenpox)
Influenza
Shigella dysentery
A nurse suspects a breach in isolation practice when a colleague:
Uses alcohol rub before entering room
Wears N95 mask for TB patient
Takes stethoscope from one isolation room to another without disinfection
Removes gloves before gown
Which statement about standard precautions is TRUE?
They apply only to patients with confirmed infection
They are required for all patients, regardless of infection status
They replace the need for isolation precautions
They apply only in surgical wards
Gloves should be changed:
Only when visibly soiled
Between care of different patients
At end of shift only
Only for surgical procedures
Which patient requires droplet precautions rather than airborne?
Pertussis
Tuberculosis
Measles
SARS-CoV-2 (COVID-19, aerosol procedures)
A nurse must place a sign outside the room indicating:
Patient’s diagnosis
Type of isolation required
Patient’s immune status
Nurse’s name
Which action is essential after leaving an isolation room?
Immediately document care
Wash hands thoroughly
Remove hospital ID
Change footwear
A nurse educating visitors about contact isolation should emphasize:
Wearing a gown and gloves when entering the room
Visiting only during morning hours
Wearing a surgical mask at all times
Sitting 3 feet away from the patient
Which infection requires contact precautions?
Tuberculosis
Varicella
MRSA
Measles
When caring for a patient under multiple isolation types (airborne + contact), the nurse should:
Apply the highest level of protection required
Only use gloves if touching secretions
Prioritize contact precautions over airborne
Discontinue airborne if contact is in place
Which scenario demonstrates a break in reverse isolation protocol?
Staff wears sterile gown and mask before entry
Room disinfected before admission
Nurse enters after handwashing
Visitor enters without mask after touching other patients
Isolation practices are most effective when:
Implemented selectively based on staff convenience
Strictly followed according to infection control guidelines
Only applied for airborne diseases
Left to patient’s preference
