The nursing assistive personnel (NAP) is working on a busy pediatric unit in a hospital. She has a cut on her hand that has not been kept covered
It hurts her to wash her hands or sanitize them, so she has been providing patient care without performing hand hygiene. Several of the patients on the pediatric unit have suffered hospital-associated infections of rotavirus. This was thought to be a result of the NAP's lack of hand hygiene. This type of disease transmission can best be described as: a. indirect.
b. natural active immunity.
c. direct.
d. natural passive immunity.
C
Hands of health care workers often transmit microorganisms. This mode of transmission is called direct transmission. Indirect transmission occurs when microorganisms are transferred to health care workers' hands from contaminated items that are part of patient care, such as a blood pressure cuff or a bedside table. Natural active immunity results from having a certain disease, such as measles, and mounting an immune response that usually lasts a lifetime. Natural passive immunity is the acquisition of an antibody by one person from another, such as a baby born with its mother's antibodies. The baby acquires these antibodies through the placenta during the last months of pregnancy. This type of immunity is of short duration, usually lasting only a few weeks to months.
