Question 1

Which pathophysiological concept should the nurse consider when developing a plan of care for a patient with myocardial ischemia?
A) There is a decrease in the amount of oxygen and glucose reaching the myocardium.
B) There is a lack of oxygen reaching the myocardium, but the supply of glucose is adequate.
C) There is a lack of glucose reaching the myocardium, but the supply of oxygen is adequate.
D) There is a complete lack of both oxygen and glucose reaching the myocardium.

Accepted Answer

Myocardial ischemia occurs when there is a reduced blood flow to the heart muscle, leading to decreased oxygen and glucose supply, which are both necessary for proper cardiac function.

Question 2

B) The nurse provides care to individuals with certain diseases.
C) The nurse studies the distribution of disease in a population.
D) The nurse provides care to a population.

Accepted Answer

Epidemiology involves studying the distribution and determinants of health-related states or events in specified populations, and nurses in this field focus on understanding how diseases spread and affect groups of people.

Question 11

Which statement represents the epidemiology nurse's calculation of the incidence of asthma?
A) There were 10 new cases of asthma diagnosed in adults ages 24 to 65 years in the past 12 months in Centerville.
B) There were a total of 3,600 people with a diagnosis of diabetes in Centerville in 2015.
C) There were 2 people diagnosed with Lyme disease in Centerville last year.
D) There were 20 cases of opioid overdose in adults ages 18 to 24 years in Centerville.

Accepted Answer

The incidence of a disease refers to the number of new cases that develop in a specific population during a specific time period. Statement A provides the number of new asthma cases diagnosed in a specific age group over the past 12 months, fitting the definition of incidence.

Question 12

In developing a plan for teaching community health nurses about the role of the nurse in epidemiology, the epidemiology nurse should include:
A) diagnosing the cause of a disease.
B) treating the disease.
C) evaluating therapeutic measures.

Accepted Answer

The answer of In developing a plan for teaching community...

Question 13

When planning community health promotion and prevention programs, the nurse should be aware that the leading cause of death in the United States is:
A) accidents.
B) suicide.
C) heart disease.
D) cancer.

Accepted Answer

Heart disease is the leading cause of death in the United States, making it a critical focus for health promotion and prevention programs.

Question 14

Which information about risk factors should the school nurse use when developing a program to reduce modifiable risk factors in high school students?
A) Sickle cell anemia is an inherited disorder.
B) Heart disease develops at an earlier age in men.
C) Many high school students do not get enough physical activity.
D) Certain ethnic variables increase the risk for chronic disease.

Accepted Answer

Many high school students do not get enough physical activity, which is a modifiable risk factor that can be addressed through a school program.

Question 15

A woman with type 1 diabetes is being seen for her first prenatal examination. Which information should the nurse include in the woman's care plan?
A) Teaching the signs and symptoms of preeclampsia
B) Explaining the fetal risk of microsomia
C) Discussing symptoms of placental abruption to report
