Question 1 of 5
Which of the following measures the frequency of new cases of the phenomenon during a given period of time?
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

Question 2 of 5
The RN is making a home visit to a female client with end-stage heart disease. She has a living will and states she will never go back to the hospital. During the visit, the RN notes that the client is pale and SOB while speaking. The RN discovers 3+ edema in both ankles and bilateral pulmonary crackles. Which intervention should the RN implement first?
Correct Answer: B
Rationale: Obtaining a peripheral O2 saturation reading is the priority intervention in this scenario. It helps assess the client's oxygenation status quickly, which is crucial in a client with signs of respiratory distress, such as shortness of breath and bilateral pulmonary crackles. Ordering a chest X-ray (
Choice
A) may be necessary later but does not address the immediate need for oxygen assessment. Obtaining an order for a complete blood count (
Choice
C) is not the priority in this situation as it does not directly address the client's respiratory distress. Instructing the patient to stay in bed (
Choice
D) does not address the underlying issue of potential hypoxia and respiratory compromise.
Question 3 of 5
What is the main focus of secondary prevention?
Correct Answer: A
Rationale: The main focus of secondary prevention is early detection and treatment of disease. This approach aims to identify health conditions in their early stages when they are easier to treat or manage effectively.
Choice B, rehabilitation, is more aligned with restoring function after an illness or injury has occurred.
Choice C, health promotion, concentrates on educating and empowering individuals to adopt healthy behaviors to prevent the onset of diseases.
Choice D, palliative care, is focused on providing comfort and improving the quality of life for individuals with serious illnesses or at the end of life, rather than on early detection and treatment.
Question 4 of 5
The nurse is assessing a client with portal hypertension. Which of the following findings would the nurse expect?
Correct Answer: C
Rationale: Ascites is a common finding in clients with portal hypertension. Portal hypertension results in increased pressure in the portal vein, leading to the development of ascites, which is the accumulation of fluid in the abdominal cavity. Expiratory wheezes (
Choice
A) are associated with respiratory conditions. Blurred vision (
Choice
B) is more commonly linked to eye disorders or neurological issues. Dilated pupils (
Choice
D) can be related to neurological conditions or drug effects, but not specifically to portal hypertension.
Question 5 of 5
Which topic should the nurse include in planning a primary prevention class for adolescents?
Correct Answer: C
Rationale: The correct topic that the nurse should include in planning a primary prevention class for adolescents is suicide risks and prevention. Adolescents are particularly vulnerable to mental health issues, including suicidal ideation. Educating them about suicide risks and prevention strategies is crucial for early intervention and support.
Choices A, B, and D are important topics, but when considering primary prevention for adolescents, addressing suicide risks and prevention takes precedence due to its immediate life-saving implications.
