1 · End-of-manual check · medium

Why is high immunisation coverage important beyond protecting each individual who is vaccinated?

  1. It reduces circulation of the organism, protecting those who cannot be vaccinated
  2. It makes the vaccine more effective in each person
  3. It allows the vaccine schedule to be shortened
  4. It removes the need for any other infection control measure in hospitals and the community
Answer and working

A. It reduces circulation of the organism, protecting those who cannot be vaccinated

High coverage reduces how much an organism circulates, which protects infants, immunosuppressed patients and those in whom the vaccine did not work. This is why coverage is measured at population level, and why falling coverage produces outbreaks among people who were never the ones declining.

2 · End-of-manual check · medium

Which question most reliably reduces hospital-acquired infection on a ward round?

  1. Which isolation precautions apply here?
  2. Is this device still needed today?
  3. Has the floor been cleaned this morning?
  4. Should a broader antibiotic be used?
Answer and working

B. Is this device still needed today?

Most hospital-acquired infection is linked to a device or procedure breaching a natural defence — catheters, cannulae, tubes and drains. Each is justified while needed and becomes pure risk once it is not, so removing it is the most direct available intervention.

3 · The Chain Of Infection · hard

Why are hospital patients more likely than the public to become infected after the same exposure?

  1. Hospital organisms are more numerous than those outside
  2. Hospital staff carry organisms that are absent elsewhere
  3. Illness, age, drugs and devices weaken their defences
  4. Patients in hospital have fewer normal flora on their skin to compete with pathogens
Answer and working

C. Illness, age, drugs and devices weaken their defences

Whether exposure becomes infection depends on dose, virulence and host defence. Hospital patients have weakened defences and breached barriers.

4 · Hand Hygiene · medium

When must hands be cleaned in relation to wearing gloves?

  1. Gloves remove the need to clean hands at all
  2. After taking gloves off at the end of the shift
  3. Before putting gloves on for sterile procedures
  4. Before putting gloves on and after taking them off
Answer and working

D. Before putting gloves on and after taking them off

Gloves become contaminated and have micro-holes; hands are contaminated when gloves are removed. Gloves are changed between patients and between dirty and clean tasks.

5 · Antimicrobial Resistance · medium

Which practice contributes to antimicrobial resistance?

  1. Reviewing antibiotics at 48-72 hours
  2. Using the narrowest effective drug
  3. Taking cultures before treatment
  4. Giving antibiotics for viral infections
Answer and working

D. Giving antibiotics for viral infections

Unnecessary use selects resistant organisms without benefit. The other three are stewardship practices that reduce resistance.

6 · Antimicrobial Resistance · medium

What is the nurse's part in antimicrobial stewardship?

  1. Stopping antibiotics when the patient feels better
  2. Choosing which antibiotic the patient receives
  3. Doubling doses when a patient is improving slowly
  4. Timely doses, prompting review, specimens first
Answer and working

D. Timely doses, prompting review, specimens first

Nurses give most doses and see the patient throughout, so timing, review prompts and specimen collection are central nursing contributions.

7 · Outbreaks · medium

In an outbreak investigation, what does a case definition do?

  1. Sets clear criteria for who counts as a case
  2. Names the person responsible for the outbreak
  3. Describes the treatment each patient receives
  4. Lists the staff on duty that week
Answer and working

A. Sets clear criteria for who counts as a case

A case definition (person, place, time and clinical criteria) lets cases be counted consistently and the outbreak described.

8 · Infection In The Community · medium

What is the cold chain in immunisation?

  1. Storing every vaccine product in a freezer at minus 20 C until the day of use
  2. Cooling the patient's arm before injection
  3. Keeping vaccines at the right temperature throughout
  4. Giving vaccines during cold weather
Answer and working

C. Keeping vaccines at the right temperature throughout

Many vaccines lose potency if too warm or frozen. Fridge temperatures are monitored and recorded.

9 · Infection At A Wound · medium

Which factor most raises a patient's risk of surgical site infection?

  1. A normal body weight
  2. Poorly controlled diabetes
  3. A low-salt diet
  4. Early mobilisation
Answer and working

B. Poorly controlled diabetes

Hyperglycaemia impairs neutrophil function and healing. Smoking, obesity, malnutrition and immunosuppression also raise the risk.

10 · Infections Carried By Insects and Water · medium

Why do repeated gut infections in children worsen malnutrition?

  1. They raise appetite and cause overeating
  2. They make children grow faster for a time, then slower, with no lasting effect
  3. They leave nutrition unaffected
  4. They impair absorption, which weakens resistance
Answer and working

D. They impair absorption, which weakens resistance

Infection and undernutrition form a cycle; water, sanitation, hygiene and feeding support break it.
