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.

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.
A patient born in 1955 had hepatitis A infection 1 year ago. According to Centers for Disease Control and Prevention (CDC) guidelines, which action should the nurse include in care when the patient is seen for a routine annual physical exam?
- A. Start the hepatitis B immunization series.
- B. Teach the patient about hepatitis A immune globulin.
- C. Ask whether the patient has been screened for hepatitis C.
- D. Test for anti-hepatitis-A virus immune globulin M (anti-HAV-IgM).
Correct Answer: C
Rationale: The correct action for the nurse to include in care when the patient is seen for a routine annual physical exam, according to CDC guidelines, is to ask whether the patient has been screened for hepatitis C. CDC guidelines recommend screening patients born between 1945 and 1965 for hepatitis C due to the high prevalence of undiagnosed cases in this age group. Starting the hepatitis B immunization series is not necessary as the patient already had hepatitis A infection. Teaching the patient about hepatitis A immune globulin is not indicated in this scenario. Testing for anti-hepatitis-A virus immune globulin M (anti-HAV-IgM) is not needed as the patient has already had hepatitis A.
Which of the following is a local sign of infection?
- A. Swelling
- B. Rapid pulse
- C. Fever
- D. High white blood count
Correct Answer: A
Rationale: A local sign of infection refers to symptoms that are specific to the area of infection. Swelling, heat, pain, and redness near the infected site are examples of local signs. In the context of infection, swelling occurs due to an accumulation of fluid and immune cells at the site of infection. Rapid pulse, fever, and high white blood count are more systemic responses to infection and not specific local signs. Rapid pulse can indicate systemic distress or sepsis, fever is a systemic response to infection, and high white blood count is a laboratory finding that suggests an immune response but is not a direct sign of infection at a specific site.
Which of the following white blood cells is the smallest and can be involved in humoral immunity?
- A. Lymphocyte
- B. Monocyte
- C. Basophil
- D. Erythrocyte
Correct Answer: A
Rationale: The correct answer is 'Lymphocyte.' Lymphocytes are the smallest type of white blood cells and play a crucial role in humoral immunity by producing antibodies. Monocytes are actually the largest white blood cells and are involved in phagocytosis rather than humoral immunity. Basophils are a type of granulocyte involved in allergic reactions, and erythrocytes are red blood cells responsible for oxygen transport, not part of the immune system.
Which risk factor places patients and residents at the greatest risk for falls?
- A. Old age
- B. Middle age
- C. Pneumonia
- D. COPD
Correct Answer: A
Rationale: Old age is a significant risk factor for falls as elderly individuals are more prone to falls due to factors like decreased balance, muscle strength, and vision. Middle age is less associated with falls compared to old age. Pneumonia and COPD are medical conditions that are not direct risk factors for falls, unlike aging which significantly increases the risk of falls.
