Nursing Elites

1. 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.

2. What is the measure of the number of existing cases of a disease in a specific population at a given time?

• A. Incidence
• B. Prevalence
• C. Mortality rate
• D. Morbidity rate

Correct answer: B

Rationale: Prevalence is the correct answer as it refers to the number of existing cases of a disease in a specific population at a given time. Incidence, on the other hand, refers to the number of new cases of a disease in a defined population over a specific period. Mortality rate is the measure of the number of deaths in a particular population due to a specific cause, while morbidity rate is the frequency of a disease in a specific population.

3. Which of the following tools is used by community health nurses to identify the health needs of a population?

• A. Health survey
• B. Medical records
• C. Patient interviews
• D. Epidemiological studies

Correct answer: D

Rationale: Epidemiological studies are used by community health nurses to identify the health needs of a population. These studies involve investigating patterns, causes, and effects of health and disease conditions in defined populations. While health surveys, medical records, and patient interviews are valuable tools in healthcare, epidemiological studies provide a broader population-based perspective essential for understanding and addressing community health needs.

4. Which of these tests with frequency would the nurse expect to monitor for the evaluation of clients with poor glycemic control in persons aged 18 and older?

• A. A glycosylated hemoglobin (A1c) should be performed during an initial assessment and during follow-up assessments, which should occur at no longer than 3-month intervals
• B. A glycosylated hemoglobin should be obtained at least twice a year
• C. A fasting glucose and a glycosylated hemoglobin should be obtained at 3-month intervals after the initial assessment
• D. A glucose tolerance test, a fasting glucose, and a glycosylated hemoglobin should be obtained at 6-month intervals after the initial assessment

Correct answer: A

Rationale: Glycosylated hemoglobin (A1c) testing every 3 months is recommended for clients with poor glycemic control to monitor their average blood sugar levels and adjust treatment as necessary. Choice A is correct as it aligns with the guideline of performing A1c testing every 3 months. Choice B is incorrect because testing at least twice a year may not provide adequate monitoring for clients with poor glycemic control. Choice C is incorrect as it only mentions testing at 3-month intervals without specifying the importance of A1c testing. Choice D is incorrect as it includes unnecessary tests like glucose tolerance test and does not emphasize the importance of more frequent A1c monitoring for clients with poor glycemic control.

5. A client with a peptic ulcer is scheduled for a vagotomy and pyloroplasty. The nurse explains that the purpose of this surgery is to:

• A. Increase acid secretion
• B. Reduce acid secretion
• C. Promote gastric emptying
• D. Remove the ulcerated area

Correct answer: B

Rationale: The correct answer is B: "Reduce acid secretion." Vagotomy is performed to reduce acid secretion by cutting the vagus nerve, which stimulates acid production. Choices A, C, and D are incorrect. A vagotomy does not increase acid secretion, promote gastric emptying, or remove the ulcerated area. It specifically aims to decrease acid production to help in the healing of peptic ulcers.
