A patient presents at a clinic with a partial-thickness burn on the left arm. The skin appears red and swollen. The patient reports the burn is very painful. What is an additional symptom of a patient with this type of burn?

Charred skin

Blisters

Pale skin

Peeling skin

Answer and Explanation

The Correct Answer is B

Partial-thickness burns are also known as second-degree burns. They involve damage to both the epidermis (the outer layer of skin) and part of the dermis (the inner layer of skin). They cause redness, swelling, pain, and blisters. Blisters are fluid-filled sacs that form as a result of damage to the skin cells and blood vessels.

They help to protect the underlying tissues from infection and further injury.

Correct Answer is C

Explanation

Marfan syndrome is a genetic disorder that affects the connective tissue, causing problems with the heart, blood vessels, eyes, bones, and joints. It is caused by a mutation in the FBN1 gene, which encodes for a protein called fibrillin-1. Marfan syndrome follows an autosomal dominant pattern of inheritance, which means that only one copy of the mutated gene is needed to cause the disorder. A person with Marfan syndrome has a 50% chance of passing on the mutated gene to each child, regardless of the gender of the parent or the child.

A. Extracellular fluid will shift into the interstitial fluid space and tissues will expand. B. Interstitial fluid will shift into the intracellular fluid space and cells will stay the same. C. Extracellular fluid will shift into the intracellular fluid space and cells will expand. D. Intracellular fluid will shift into the extracellular fluid space and cells will shrink.

Correct Answer is C

Explanation

Osmolarity is a measure of the concentration of solutes in a solution. When the osmolarity of the bloodstream increases due to blood loss, water will move from areas of lower osmolarity to areas of higher osmolarity by osmosis. This means that water will move from the extracellular fluid (the fluid outside the cells) to the intracellular fluid (the fluid inside the cells) to balance the osmotic pressure. As a result, the extracellular fluid volume will decrease and the intracellular fluid volume will increase, causing the cells to expand.
