The chain of infection includes the ________________.
- A. germ, agent, reservoir, exit portal, mode of transmission, entry port, and susceptible host
- B. active natural, active artificial, passive natural, and passive artificial
- C. opportunism, weakness, immunity, and colonization
- D. intrinsic, extrinsic, internal, and external transmission
Correct Answer: A
Rationale: The chain, or cycle, of infection includes the germ (microorganism), agent, reservoir, exit portal, mode of transmission, entry port, and susceptible host. This sequence describes how infections are passed from one person to another. Choice B is incorrect because it refers to types of immunity, not components of the chain of infection. Choice C is also incorrect as it lists terms unrelated to the chain of infection. Choice D is incorrect as it describes transmission types, not components of the chain of infection. Understanding the chain of infection is crucial in preventing the spread of infections by breaking one or more links in the chain, such as interrupting the mode of transmission through proper hand hygiene.

Mobility is an important human function. The hazards of immobility lead to many physical and emotional problems. Immobility can lead to detrimental cardiac, muscular, respiratory, skeletal, urinary, gastrointestinal, skin, and emotional changes. Which of the following is an example of a skeletal hazard of immobility?
- A. Contractures.
- B. Constipation.
- C. Calcium loss.
- D. Catabolism.
Correct Answer: C
Rationale: All choices are hazards of immobility, but only calcium loss from the bones is a skeletal system impairment that results from immobility. Contractures are muscle shortening due to prolonged positioning, which affects the muscular system. Constipation is a gastrointestinal issue. Catabolism is a metabolic process, not specific to the skeletal system.
Which information given by a 70-year-old patient during a health history indicates to the nurse that the patient should be screened for hepatitis C?
- A. The patient had a blood transfusion in 2005
- B. The patient used IV drugs about 20 years ago
- C. The patient frequently eats in fast-food restaurants
- D. The patient traveled to a country with poor sanitation
Correct Answer: B
Rationale: The correct answer is 'The patient used IV drugs about 20 years ago.' Any patient with a history of IV drug use should be tested for hepatitis C due to the increased risk of transmission through sharing needles. Blood transfusions given after 1992, when an antibody test for hepatitis C became available, do not pose a risk for hepatitis C. Hepatitis C is not spread by the oral-fecal route, so contaminated food or traveling to countries with poor sanitation are not direct risk factors for hepatitis C.
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.
You are turning your patient in bed and notice that a confused and lethargic patient had loose car keys and lipstick in the bed and had been lying on them. What is this person at risk for due to all three of these factors: confusion, lethargy, and items in the bed?
- A. Falls
- B. Skin breakdown
- C. Apnea
- D. Lack of mobility
Correct Answer: B
Rationale: This patient is at great risk for skin breakdown due to the presence of three specific risk factors: confusion, lethargy, and items in the bed. While confusion puts the patient at risk for falls, confusion and lethargy together may lead to a lack of mobility. However, skin breakdown is the primary concern in this scenario as it is associated with all three risk factors - confusion, lethargy, and the presence of items in the bed. Therefore, the correct answer is 'Skin breakdown'.
When teaching a Vietnamese patient who has been treated for pneumonia and needs to complete her antibiotic regimen at home, what is an important cultural component to consider?
- A. Cupping will help to pull toxins from the body
- B. Coining will help to release the wind or bad energy from the body
- C. Once symptoms disappear there is no longer an illness
- D. Most households consist of at least 3 generations
Correct Answer: C
Rationale: The correct answer is 'Once symptoms disappear there is no longer an illness'. In Vietnamese culture, there is a belief that once symptoms go away, the illness is no longer present and does not require further treatment. This is crucial to understand when educating Vietnamese patients about completing their antibiotic regimen. Choices A and B (cupping and coining) are traditional Vietnamese healing practices that are not directly related to completing antibiotic therapy. Choice D, about households consisting of multiple generations, is not directly relevant to the completion of antibiotic treatment for pneumonia in this context.
