Answer to Question 1

D
An example of a descriptive study would be studying a group of siblings to identify the effects of having a family member diagnosed with schizophrenia. Descriptive studies describe some aspect of an element being studied. Studying nursing students being tested before and after learning a skill and studying the effects of a new vaccine being tested on half the subjects while the other half receive saline injections are examples of quasi-experimental studies. Comparing individuals with depression to individuals without depression is a correlational study.

Answer to Question 2

C
The client exhibiting chronic fatigue and a sense of nonrestful sleep, daytime sleepiness, hypertension, multiple awakenings throughout the night, and snoring is most like experiencing obstructive sleep apnea. In this condition the tissues of the upper airway relax so profoundly during deep sleep that they collapse and obstruct the flow of air into the lungs. When obstruction is only partial, snoring results, but when complete the client often arouses from sleep. Obstructive sleep apnea may increase a person's risk of developing hypertension, heart disease, and depression.
