Asepsis is defined as ________________.
- A. the absence of all microorganisms
- B. the absence of disease-causing germs
- C. a urinary infection
- D. a pathogenic infection
Correct Answer: B
Rationale: Asepsis is defined as the absence of disease-causing germs. It is surgical asepsis that is defined as the absence of all microorganisms, including spores. A pathogenic infection is an invasion of the body by a pathogen, or disease-causing germ, and a urinary infection is only one type of infection.

Sinusitis is caused by:
- A. Bacteria
- B. Fungus
- C. Virus
- D. Any of the above
Correct Answer: D
Rationale: Sinusitis can be caused by bacteria, viruses, or fungi. While bacterial infections are the most common cause, viral or fungal infections can also lead to sinusitis. Therefore, the correct answer is 'Any of the above.' Choices A, B, and C are incorrect because they only represent individual causes of sinusitis, whereas choice D encompasses all possible causes.
The clinic nurse teaches a patient with a 42 pack-year history of cigarette smoking about lung disease. Which information will be most important for the nurse to include?
- A. Options for smoking cessation
- B. Reasons for annual sputum cytology testing
- C. Erlotinib (Tarceva) therapy to prevent tumor risk
- D. Computed tomography (CT) screening for lung cancer
Correct Answer: A
Rationale: The most critical information for the nurse to provide to a patient with a significant smoking history is options for smoking cessation. Smoking is the primary cause of lung cancer, making smoking cessation essential in reducing the risk of developing the disease. Annual sputum cytology testing is not a standard screening test for lung cancer; instead, CT scanning is being explored for this purpose. Erlotinib therapy is used in lung cancer treatment but not for preventing tumor risk in individuals without cancer. CT screening for lung cancer is still under investigation and is not primarily aimed at prevention but rather early detection in high-risk individuals.
Select the age group that is coupled with an infectious disease that is most common in this age group.
- A. Infants: High bilirubin
- B. Pre-School and School Age Children: Shingles
- C. Young Adults and Teenagers: Sexually transmitted diseases
- D. The Elderly: Malaria
Correct Answer: C
Rationale: Young adults and teenagers are at the highest risk for sexually transmitted diseases due to their sexual activity. High bilirubin is a laboratory finding related to jaundice and not an infectious disease. Shingles is more common in the elderly population, not in pre-school and school-age children. Malaria is not most common in the elderly; it is prevalent in regions with specific mosquito vectors. Therefore, the correct answer is that young adults and teenagers are most commonly associated with sexually transmitted diseases.
What action by the nurse will be most effective in decreasing the spread of pertussis in a community setting?
- A. Providing supportive care to patients diagnosed with pertussis
- B. Teaching family members about the importance of careful handwashing
- C. Teaching patients about the necessity of adult pertussis immunizations
- D. Encouraging patients to complete the prescribed course of antibiotics
Correct Answer: C
Rationale: The most effective action by the nurse to decrease the spread of pertussis in a community setting is to teach patients about the necessity of adult pertussis immunizations. The increased rate of pertussis in adults is often attributed to waning immunity after childhood immunization. Immunization is highly effective in protecting communities from infectious diseases. While teaching about handwashing is important for overall infection control, pertussis is primarily spread through respiratory droplets and contact with secretions. Providing supportive care does not significantly impact the disease course or transmission risk. Encouraging completion of antibiotics may help reduce transmission, but patients likely have already spread the disease by the time the diagnosis is made. Therefore, the emphasis should be on prevention through immunization to reduce the spread of pertussis.
Mr. Freeman has difficulty getting out of bed. The nurse should encourage Mr. Freeman to ______________.
- A. ask for assistance before getting out of bed.
- B. remain in bed because it is safer and he will not fall.
- C. instruct him to stand up quickly from the bed.
- D. lean forward and push up and off the bed.
Correct Answer: A
Rationale: The nurse should encourage Mr. Freeman to use his call bell and ask for assistance before getting out of bed. This can prevent him from falling. Patients should not stay in bed; they should be encouraged to get out of bed as much as possible to prevent complications like pressure ulcers and muscle weakness. Instructing a patient to stand up quickly from the bed is unsafe as it can lead to dizziness and falls. Similarly, leaning forward and pushing off the bed can increase the risk of falls and should be avoided. Asking for assistance is the safest and most appropriate option to ensure patient safety and prevent accidents.
