| 1. | A nurse is caring for a client with Lyme disease. Which of the following causes Lyme disease? | |
| A) | Rickettsiae | |
| B) | Fungi | |
| C) | Protozoans | |
| D) | Mycoplasmas | |
| Ans: | A | |
| Feedback: | ||
| Rickettsiae that resemble bacteria cause Lyme disease. Intermediate life forms such as fleas, ticks, lice, or mites transmit rickettsial diseases to humans. Fungi include yeasts and molds, which cause infections in the skin, mucous membranes, hair, and nails. Examples of fungal infections include ringworm, athlete’s foot, and vaginal yeast infection. Protozoans are single-celled animals classified according to their ability to move. Mycoplasmas infect the surface linings of the respiratory, genitourinary, and gastrointestinal tracts. Fungi, protozoans, and mycoplasmas do not cause Lyme disease. | ||
| 2. | A nurse is attending to a client with an infectious disease. After changing the linen and caring for the patient, the nurse uses an alcohol-based hand rub. Which of the following is a reason for the nurse to use an alcohol-based hand rub? | |
| A) | It destroys microbial spores on the skin. | |
| B) | It provides the greatest reduction in microbial counts. | |
| C) | It destroys potentially harmful keratin skin cells. | |
| D) | It alters viral replication on the skin. | |
| Ans: | B | |
| Feedback: | ||
| The nurse uses an alcohol-based hand rub as it provides the fastest and greatest reduction in microbial counts on the skin. Other advantages include: alcohol-based hand rubs are more accessible because they do not require sinks or water; they increase compliance because they are easier to perform; they reduce costs by eliminating paper towels and waste management; and they are less irritating and drying than soap because they contain emollients. They can kill viruses but do not alter viral replication. They do not kill skin cells and they are ineffective against some spores. | ||
| 3. | A nurse is observing the housekeeping staff when they are cleaning the premises of a health care facility. Which of the following principles should the housekeeping staff follow for medical asepsis? | |
| A) | Wet-mop floors to avoid distributing microorganisms. | |
| B) | Clean grossly dirty areas before less-soiled areas. | |
| C) | Dust the furniture with a dry cloth to avoid spreading microorganisms. | |
| D) | Place clean items carefully on the floor. | |
| Ans: | A | |
| Feedback: | ||
| Housekeepers who follow the principles of medical asepsis carry out concurrent disinfection methods. The housekeeping personnel should wet-mop floors and damp-dust furniture to avoid distributing microorganisms on dust and air currents. They should never place clean items on the floor or on the furniture. They should always clean less-soiled areas before grossly dirty ones. | ||
| 4. | A home-care nurse is caring for an elderly client with a throat infection at the client’s residence. The nurse uses a stainless steel instrument to examine the client’s throat. At what temperature should the device be boiled to sterilize it? | |
| A) | 5 minutes at 152°F | |
| B) | 15 minutes at 152°F | |
| C) | 5 minutes at 212°F | |
| D) | 15 minutes at 212°F | |
| Ans: | D | |
| Feedback: | ||
| Boiling water is a convenient way to sterilize items used at home. To be effective, contaminated equipment needs to be boiled for 15 minutes at 212°F or longer in places at higher altitudes. | ||
