Exam Cram NCLEX RN Practice Questions Questions
Question 1 of 5
The chain of infection includes the ________________.
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.
Question 2 of 5
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?
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.
Question 3 of 5
Mary T. was admitted to a nursing home on May 1st. On July 4th, she was diagnosed with a skin infection. This infection is considered a ________________ infection.
Correct Answer: A
Rationale: The correct answer is 'nosocomial.' A nosocomial infection is defined as one that is not present upon admission to a healthcare facility but instead occurs during the patient's stay. In this case, since Mary was diagnosed with a skin infection after being admitted to the nursing home, it is considered a nosocomial infection. Nosocomial infections are a significant concern in healthcare settings, and infection control measures are in place to prevent their spread. Choices B, C, and D are incorrect. 'Systemic' refers to a condition affecting the entire body, not specific to a healthcare setting. 'Resident flora' and 'resident aura' are not commonly used terms in healthcare and do not relate to infections acquired in healthcare facilities.
Question 4 of 5
Which of the following is a local sign of infection?
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.
Question 5 of 5
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?
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.
