What is a clinical manifestation of dehydration?
Peripheral edema
Oliguria
Elevated blood pressure
Dyspnea
The Correct Answer is B
Oliguria is a condition where the urine output is less than normal, usually less than 500 mL per day in adults. Oliguria can be a sign of dehydration, which occurs when the body loses more water than it takes in. Dehydration can cause various symptoms such as thirst, dry mouth, headache, dizziness, fatigue, and confusion.
Dehydration can also affect kidney function and lead to electrolyte imbalances and acid-base disorders.

Correct Answer is D
Explanation
Diabetes insipidus is a disorder of water balance caused by a deficiency of antidiuretic hormone (ADH) or a resistance to its action. ADH regulates the reabsorption of water in the kidneys and prevents excessive urine output. Without enough ADH or with reduced sensitivity to it, the kidneys produce large amounts of diluted urine, leading to frequent urination and thirst. Chronic fatigue and mild confusion may result from dehydration and electrolyte imbalance. Serum glucose is not affected by diabetes insipidus, unlike diabetes mellitus, which is a disorder of carbohydrate metabolism.
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.
