A patient is bleeding severely from a severed femoral artery high in the groin region. Which of the following would MOST likely control the bleeding?

Apply a topical hemostatic agent with direct pressure

A 70-year-old man presents with a severe nosebleed. His medical history includes COPD, depression, and a hemorrhagic stroke 3 years ago. His BP is 190/110 mm Hg, his pulse is 100 beats/min, and his respirations are 24 breaths/min. His medications include albuterol, sertraline (Zoloft), and multivitamins. Which of the following is MOST likely causing his nosebleed today?

High blood pressure

Which of the following occurs after tissues are injured?

Platelets collect at the injury site

Which of the following organs can tolerate inadequate perfusion for 2 to 3 hours?

Skeletal muscle

Blood stasis, changes in the vessel wall, and certain medications affect the:

ability of the blood to effectively clot.

Most cases of external bleeding from an extremity can be controlled by:

applying local direct pressure.

The smaller vessels that carry blood away from the heart and connect the arteries to the capillaries are called the:

arterioles.

An organ or tissue may be better able to resist damage from hypo perfusion if the:

body's temperature is considerably less than 98.6°F (37.0°C).

In nontrauma patients, an early indicator of internal bleeding is:

dizziness upon standing.

A 39-year-old male sustained a large laceration to his leg during an accident with a chainsaw and is experiencing signs and symptoms of shock. You should first:

follow appropriate standard precautions

Gastrointestinal bleeding should be suspected if a patient presents with:

hematemesis.

The ability of a person's cardiovascular system to compensate for blood loss is MOST related to:

how rapidly he or she bleeds.

Early signs and symptoms of intra-abdominal bleeding include:

pain and distention

The systemic veins function by:

returning deoxygenated blood back to the heart.
