A strain is an injury to a muscle or a tendon that occurs when it is stretched or torn beyond its normal range of motion.

Explanation

A. Correct. Checking the pH of the gastric aspirate is the most reliable method to verify the correct placement of the NG tube. Gastric aspirate typically has an acidic pH (pH < 5), indicating that the tube is in the stomach.
B. Observing the color of the gastric aspirate after adding blue dye to the formula is not a standard or recommended method for verifying NG tube placement.
C. Auscultating over the epigastrium may help to identify the presence of air in the stomach, but it does not confirm that the NG tube is correctly placed in the stomach or the intestines.
D. Measuring the length of the inserted NG tube can help determine the distance from the nose to the stomach, but it does not ensure correct placement in the stomach.

A. Charred skin B. Blisters C. Pale skin D. Peeling skin

Correct Answer is B

Explanation

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.
