Answer:
The correct option is : c. subdural space-contains cerebrospinal fluid
Explanation:
The meninges are the protective membranes covering spinal cord and the brain. The meninges is composed of three membrane layers- dura mater, arachnoid mater, pia mater.
Dura mater is the thick durable outermost membrane of the meninges.
Arachnoid mater: It is the middle layer, present between the dura mater and the pia mater. It has a fine spider web-like appearance and thus it is named after the Greek word Arachne, meaning spider.
The pia mater or pia: It is a very thin and delicate innermost layer, which is present on the surface of the brain. The pia mater is loosely connected to arachnoid layer and is fused or firmly bound to the surface of the brain.
The space between arachnoid mater and pia is known as the subarachnoid space. This space is filled with the cerebrospinal fluid.
Therefore, subdural space-contains cerebrospinal fluid is incorrect and thus not the correct match.
Answer: The dependent variable is weight; the independent variable is exercise.
Explanation:
The dependent variable refers to the variable which depends on the independent variables which are the other factors that are measured.
The dependent variable is expected to change due to the manipulation of the independent variables. Since the researcher is investigating the effects of exercise on weight, the dependent variable is weight while the independent variable is exercise.
The ICD-10-CM code(s) is/are reported for the patient would be <u>E66.01, Z68.42.</u>
The most common surgical procedure for morbid obesity is Laparoscopic Roux-en-Y gastric bypass (LRYGB).
It is reported to be the gold standard in the surgical treatment of morbid obesity as it provides long-term weight loss and has acceptable morbidity and mortality.
Code E66* is the diagnosis code used for Overweight and Obesity. It is a disorder marked by an abnormally high, unhealthy amount of body fat. Excess body weight can come from fat, muscle, bone, and/or water retention.
