B. I should tell my friends and family not to send flowers.
D. I should bring in my electric razor to shave.
Explanation -
Sending fresh flowers would have bacteria and would in return cause infection to the patient because of the suppressed functioning of the bone marrow. Use of electric razors would decrease the chances of bleeding unlike razor blades.
Brushing and flossing three times a day might lead to bleeding gums. The visitors who themselves are infected should avoid meeting the patient because the patient has full potential to get the infection because the patient’s immune system is compromised.
