What is the first threat to life from a massive third-degree burn?
dehydration
unbearable pain
loss of immune function
infection
The Correct Answer is A
A. dehydration: Massive third-degree burns destroy the skin barrier, allowing significant fluid loss through evaporation. This leads to hypovolemic shock, which is the most immediate and life-threatening concern after a severe burn.
B. unbearable pain: Third-degree burns often destroy nerve endings in the affected area, so pain may be minimal at the burn site itself. Pain is distressing but not the first life-threatening issue.
C. loss of immune function: Severe burns compromise the skin’s protective role, increasing susceptibility to infection. However, immune compromise develops over hours to days, making it a secondary threat compared to fluid loss.
D. infection: Infection is a major risk in burn patients due to the loss of the protective barrier, but it typically develops later. Immediate fluid loss poses a more urgent threat to life in the first hours following the burn.

Correct Answer is B
Explanation
A. skeletal MT:Skeletal muscle tissue is under voluntary control and is not found in the walls of the uterus. It is primarily responsible for movements of the skeleton rather than involuntary contractions needed for labor.
B. smooth MT:Smooth muscle tissue makes up the bulk of the uterine wall (myometrium) and is responsible for powerful, rhythmic contractions during labor. These contractions are involuntary and essential for expelling the fetus.
C. stratified squamous ET:Stratified squamous epithelium is a protective tissue commonly found in areas exposed to friction, such as the skin and vaginal canal. It does not contribute to the contractile activity of the uterus.
D. elastic cartilage CT:Elastic cartilage provides flexibility and support in structures like the ear and epiglottis. It has no role in uterine structure or the generation of contractions during labor.
Correct Answer is B
Explanation
A. bone; adipose:Bone is the most solid connective tissue, providing structural support and protection. Adipose tissue, while soft and pliable, is not the most fluid connective tissue since it primarily stores fat rather than circulating or transporting substances.
B. bone; blood:Bone is the densest and most rigid connective tissue, providing support, protection, and leverage for movement. Blood is the most fluid connective tissue, circulating throughout the body to transport nutrients, gases, hormones, and waste products.
C. hyaline cartilage; areolar:Hyaline cartilage is firm but not as rigid as bone, and areolar connective tissue is loose and supportive but not fluid; it serves as a cushioning and binding tissue rather than a circulating medium.
D. fibrocartilage; areolar:Fibrocartilage is tough and less compressible than hyaline cartilage but is still less solid and rigid than bone. Areolartissue is a viscous, gel-like matrix that is not the most fluid type.
