Final answer:
The infection control nurse in the nursing home would likely ask Harold Johnson the question, "During the past 30 days, for about how many days did poor health keep you from doing your usual activities?" This question would provide information about any recent health issues or illnesses that Mr. Johnson may have experienced, which could potentially indicate a weakened immune system or increased vulnerability to infections.
