MCQs: Isolation Definition & Precautions (Q1-20)

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
