Rationale: The correct answer is C: Blood pressure. Vital signs are measurements that indicate the body's basic functions. Blood pressure is a key vital sign as it reflects the force of blood against the walls of the arteries. Monitoring blood pressure helps assess cardiovascular health. Glucose level (A) is important for assessing blood sugar levels, but it is not considered a vital sign. Urine output (B) is crucial for assessing kidney function, but it is not a vital sign. Blood count (D) refers to various components of blood like red blood cells, white blood cells, and platelets, but it is not a direct measurement of a person's vital signs.

This includes wearing gloves and gowns when in contact with the patient or their environment. Airborne Precautions (A) are for diseases spread through tiny droplets in the air. Droplet Precautions (B) are for diseases spread through larger droplets. Standard Precautions (D) combine practices to prevent the spread of infection and are used for all patients, not just those with specific diseases spread through direct contact.

Correct Answer: A

Rationale: The correct answer is A: First-degree burn. A superficial burn, also known as a first-degree burn, affects only the outer layer of the skin (epidermis). It is characterized by redness, minor swelling, and pain but does not blister. Second-degree burns (choice C) involve the epidermis and part of the dermis, causing blistering. Third-degree burns (choice B) affect all layers of the skin and may involve underlying tissues, while fourth-degree burns (choice D) extend even deeper, affecting muscles and bones. Therefore, the superficial nature of the burn described in the question aligns with a first-degree burn, making it the correct choice.
