Which of the following measures the frequency of new cases of the phenomenon during a given period of time?
- A. prevalence rate
- B. proportionate mortality rate
- C. case fatality rate
- D. incidence rate
Correct Answer: D
Rationale: The correct answer is D, incidence rate. Incidence rate measures the frequency of new cases of a phenomenon, providing important information about the risk of developing the condition. Prevalence rate (choice A) reflects both old and new cases, proportionate mortality rate (choice B) is the proportion of deaths due to a specific cause, and case fatality rate (choice C) measures the proportion of deaths among confirmed cases, not just new cases.

While explaining an illness to a 10-year-old, what should the nurse keep in mind about the cognitive development at this age?
- A. They are able to make simple associations of ideas
- B. They are able to think logically in organizing facts
- C. Interpretation of events originates from their own perspective
- D. Conclusions are based on previous experiences
Correct Answer: B
Rationale: Correct answer: At the age of 10, children are in the stage of concrete operational thought, where they can think logically and organize facts. Choice A is incorrect as simple associations of ideas are more characteristic of earlier developmental stages. Choice C is incorrect as while children at this age are developing perspective-taking skills, their interpretations are not solely limited to their own perspective. Choice D is incorrect as while previous experiences influence their thinking, the ability to think logically and organize facts is more prominent in this stage of cognitive development.
Postoperative orders for a client undergoing a mitral valve replacement include monitoring pulmonary artery pressure together with pulmonary capillary wedge pressure with a pulmonary artery catheter. This action by the nurse will assess
- A. Right ventricular pressure
- B. Left ventricular end-diastolic pressure
- C. Acid-Base balance
- D. Coronary artery stability
Correct Answer: B
Rationale: The correct answer is B: Left ventricular end-diastolic pressure. Pulmonary capillary wedge pressure is used to assess left ventricular end-diastolic pressure. This measurement provides valuable information on the filling pressure of the left ventricle. Choices A, C, and D are incorrect because monitoring pulmonary capillary wedge pressure does not directly assess right ventricular pressure, acid-base balance, or coronary artery stability.
A key component of primary prevention strategies is:
- A. aggressive interventions
- B. detection
- C. culture
- D. education
Correct Answer: D
Rationale: The correct answer is 'D: education.' Education plays a vital role in primary prevention strategies by empowering individuals with knowledge and skills to prevent the onset of diseases. Through education, people can make informed decisions about their health, adopt healthy behaviors, and engage in preventive measures. Choice A, 'aggressive interventions,' is incorrect as primary prevention focuses on proactive measures to avoid the development of diseases rather than aggressive reactive interventions. Choice B, 'detection,' is more aligned with secondary prevention, which involves early identification of diseases. Choice C, 'culture,' while important in shaping health behaviors, is not a key component specifically in primary prevention strategies.
During the care of a client with Legionnaire's disease, which finding would require the nurse's immediate attention?
- A. Pleuritic pain on inspiration
- B. Dry mucus membranes in the mouth
- C. A decrease in respiratory rate from 34 to 24
- D. Decrease in chest wall expansion
Correct Answer: D
Rationale: A decrease in chest wall expansion suggests that the client may be experiencing a serious complication, such as worsening pneumonia or respiratory failure, requiring immediate medical attention. This finding indicates a potential decrease in lung function, which could lead to respiratory distress. Pleuritic pain on inspiration may be related to the disease process but does not indicate an immediate need for intervention. Dry mucus membranes in the mouth may require attention but are not as critical as a decrease in chest wall expansion. A decrease in respiratory rate could be concerning but is not as urgent as a decrease in chest wall expansion, which directly impacts respiratory function.
A client with terminal cancer is experiencing severe pain. The nurse plans to implement which of the following pain management strategies?
- A. Administer analgesics on a fixed schedule
- B. Administer analgesics only when the client requests
- C. Use non-pharmacological methods only
- D. Increase the dose of analgesics when the client complains of pain
Correct Answer: A
Rationale: Administering analgesics on a fixed schedule is the most appropriate pain management strategy for a client with terminal cancer experiencing severe pain. This approach ensures consistent pain control and helps prevent breakthrough pain. Administering analgesics only when the client requests (Choice B) may lead to uncontrolled pain as the client may delay requesting medication until the pain becomes unbearable. Using non-pharmacological methods only (Choice C) may not provide adequate pain relief for a client experiencing severe pain. Increasing the dose of analgesics when the client complains of pain (Choice D) may result in inconsistent pain control and could lead to potential overdose or adverse effects.
