Select the correct statement regarding adipose tissue.
It is a form of dense connective tissue.
It is composed mostly of extracellular matrix.
Most of the cell volume is occupied by the nucleus.
Mature adipocytes are highly mitotic.
Its primary function is triglyceride storage.
Correct Answer : E
A. Adipose tissue is not classified as dense connective tissue. Adipose tissue, on the other hand, is a type of loose connective tissue that is primarily composed of adipocytes (fat cells) and has a relatively sparse extracellular matrix compared to dense connective tissues.
B. Adipose tissue is composed mainly of adipocytes (fat cells), which occupy most of the tissue’s volume. The extracellular matrix (ECM) in adipose tissue is relatively minimal compared to other types of connective tissue.
C. In adipocytes, most of the cell volume is occupied by a large lipid droplet rather than the nucleus. The nucleus is relatively small and located at the periphery of the cell, while the central portion of the cell is primarily filled with fat storage.
D. Mature adipocytes are not highly mitotic. Adipocytes have a limited ability to divide. Instead, the number of adipocytes can increase primarily through the differentiation of precursor cells (preadipocytes) into mature adipocytes, not through the division of existing adipocytes.
E. The primary function of adipose tissue is the storage of triglycerides (fats). Adipocytes store energy in the form of triglycerides, which can be mobilized when needed for energy. Additionally, adipose tissue plays roles in insulation, cushioning, and hormone production, but triglyceride storage is its main function.

Correct Answer is A
Explanation
A. Severe, prolonged depression has been shown to increase a person's risk for physical illness. Chronic depression can lead to or exacerbate a range of health issues, including cardiovascular disease, weakened immune function, and gastrointestinal problems. The stress and physiological changes associated with depression can contribute to poorer health outcomes and a higher incidence of physical illnesses.
B. Severe, prolonged depression does have an effect on physical health, and the impact is generally detrimental rather than neutral. Ignoring the link between mental health and physical health overlooks the extensive evidence showing how chronic depression can affect physical well-being.
C. Severe, prolonged depression does not typically decrease the risk of physical illness. Instead, it generally increases the risk due to the negative effects on the body’s systems and overall health.
D. Severe, prolonged depression has more than just a little effect on physical health. Its impact is significant and can lead to a range of physical health problems, including increased susceptibility to infections, chronic diseases, and other health complications.
Correct Answer is B
Explanation
A. This principle relates to protecting patient information. It is not relevant to this scenario.
B. This principle respects the patient's right to self-determination. By disregarding the client's preference for walking with her daughter, the nursing assistant violated the client's autonomy.
C. This principle involves doing good for the patient. While the nursing assistant might have intended to benefit the client by encouraging exercise, it was done at the expense of the client's autonomy.
D. This principle involves avoiding harm to the patient. While the client was upset, there is no evidence of physical harm in this situation.
