Nokea
A client visits the clinic reporting a circular rash on the upper right arm. The rash is diagnosed as tinea corporis. For what type of infection does the nurse anticipate the client will be treated?
- A. Rickettsiae
- B. Protozoans
- C. Mycoplasma
- D. Fungus
Correct Answer: D
Rationale: One type of fungal infection is superficial (dermatophytoses), which affect the skin, hair, and nails; examples include tinea corporis, or ringworm, and tinea pedis, also known as athlete's foot. Rickettsiae, protozoans, and mycoplasma have different characteristics and transmission than fungus.

The nurse is caring for a client who has acquired immunodeficiency disease (AIDS) and has developed oral thrush. What type of infection is the nurse aware that has developed due to the immunocompromised state of the client?
- A. Acute
- B. Chronic
- C. Secondary
- D. Opportunistic
Correct Answer: D
Rationale: An opportunistic or superinfection occurs among immunocompromised hosts. Examples would be yeast infections in the mouth, bladder infections, gastroenteritis, and Pneumocystis carinii. An acute infection has a sudden onset with serious and sometimes life-threatening manifestations. A chronic infection is an extended infection that resists treatment. A secondary infection is a complication of some other disease process that occurred first.
A family member wants to donate blood for a client who needs a blood transfusion. What information from the family member would make them ineligible for donation?
- A. The family member was serving in the military in England in 1993 for 2 years.
- B. The family member had a surgical procedure 4 years previously for an inguinal hernia.
- C. The family member received a blood transfusion 10 years previously at a hospital in Canada.
- D. The family member takes an antihypertensive medication for control of blood pressure.
Correct Answer: A
Rationale: The American Red Cross bans blood collection from anyone who has lived in the United Kingdom for a total of 6 months or longer between 1980 and 1996, lived in various countries in Europe including while serving in the military since 1980, received a blood transfusion in the United Kingdom, or lived 5 or more years in various European countries from 1980 to the present. There is a higher risk among these potential donors for BSE or 'mad cow disease.' The other answers are not exclusion criteria for donating blood.
The nurse is giving an educational talk to a local parent-teacher association. A parent asks how to help the family avoid community-acquired infections. What would be the nurse's best response to help prevent and control community-acquired infections?
- A. Encourage your family to adopt a healthy diet and exercise regimen.
- B. Encourage your family to stop smoking.
- C. Make sure your family has all their childhood immunizations.
- D. Make sure your family has regular check-ups.
Correct Answer: C
Rationale: To help prevent and control community-acquired infections, nurses should encourage childhood immunizations. Vaccines stimulate the body to produce antibodies against a specific disease organism. The immunization protects children as well as adults who may not have developed sufficient immunity. Following a proper diet and exercise regimen and going for regular check-ups are important, but these measures do not help prevent or control community-acquired infections. Smoking cessation does not reduce the risk of such infections either.
The nurse gave a client an injection and, when attempting to recap the needle, sustained a needlestick injury to the finger. What is the priority action by the nurse?
- A. Report the injury or exposure to the supervisor.
- B. Document the injury in writing.
- C. Receive instructions on monitoring potential symptoms and medical follow-up.
- D. Receive the most appropriate postexposure prophylaxis.
Correct Answer: A
Rationale: Should needlestick injury or other exposure to a potential blood-borne pathogen occur, healthcare workers are advised to follow postexposure recommendations; report the injury or exposure to one's supervisor immediately; document the injury in writing; identify the person or source of blood; obtain the HIV and HBV statuses of the source of blood, if it is legal to do so. Unless the client gives permission, testing and revealing HIV status are prohibited. Obtain counseling on the potential for infection. Receive the most appropriate postexposure prophylaxis; be tested for disease antibodies at appropriate intervals. Receive instructions on monitoring potential symptoms and medical follow-up.
A client arrives at the clinic reporting vaginal discharge after having sexual intercourse 1 week ago. The client is diagnosed with gonorrhea and given a prescription for treatment. What type of infection transmission does the nurse understand occurred?
- A. Direct contact
- B. Droplet
- C. Airborne
- D. Vehicle
Correct Answer: A
Rationale: The route of transmission for a sexually transmitted disease is by direct contact. An infected person transmits the infection to a susceptible person. A droplet transmission is a spray of moist particles within a 3-foot radius of an infected person. An airborne transmission is suspension and transport on air currents beyond 3 feet. An infection transmitted by vehicle is on or in contaminated food, water, objects, or equipment.
