Which of the following would be the most likely cause of an iatrogenic disease?
An inherited disorder from your mother
A combination of specific etiologic disorders
An unwanted effect of a prescription drug
Prolonged exposure to toxic chemicals
Exposure while lying in a hospital bed
The Correct Answer is C
A. An inherited disorder from your mother: Inherited disorders are genetic and not caused by medical intervention - not iatrogenic.
B. A combination of specific etiologic disorders: This describes multifactorial disease causation, not specifically caused by healthcare actions.
C. An unwanted effect of a prescription drug: Iatrogenic disease is any adverse condition caused by medical treatment or diagnostic procedures - adverse drug effects are classic examples.
D. Prolonged exposure to toxic chemicals: Environmental/toxic exposures can cause disease but are not necessarily iatrogenic unless caused by medical care.
E. Exposure while lying in a hospital bed: This is vague; hospital-acquired infections can be iatrogenic, but the best single choice describing iatrogenic cause is adverse effect of a prescription drug.

Correct Answer is C
Explanation
A. 70-year-old with congestive heart failure: Older age and chronic illness can increase infection risk (reduced reserve, hospitalizations), but CHF itself does not specifically cause profound immune suppression.
B. 18-year-old with diabetes: Diabetes (especially if poorly controlled) increases susceptibility to infection and some opportunists, but risk depends on glycaemic control and complications.
C. 24-year-old who is immunocompromised: Immunocompromised individuals (e.g., from HIV, chemotherapy, immunosuppressive drugs) have impaired host defenses and are at greatest risk for opportunistic infections.
D. 30-year-old with pneumonia: Pneumonia is an acute infectious illness that can weaken the host, but it does not by itself confer the same chronic susceptibility to opportunistic pathogens as an immunocompromised state.
Correct Answer is B
Explanation
A. sutured surgical wound: Sutured wounds have edges approximated and heal by primary intention (direct epithelialization with minimal scarring).
B. stage IV ulcer: Stage IV pressure/decubitus ulcers have large tissue loss and damaged margins so they heal by secondary intention (granulation, contraction, lots of scar tissue).
C. sunburn: Superficial epithelial injury (sunburn) typically heals by regeneration of epithelium, not secondary-intention wound healing.
D. paper cut: Small clean lacerations with approximated edges heal by primary intention after closure (or spontaneously with minimal scarring).
