Understanding Hypovolemic Shock

What is the primary cause of hypovolemic shock?

• Excessive vasodilation

• Increased cardiac output

• Low blood volume

• High blood pressure

What does preload refer to in the context of the heart?

• The amount of blood left in the heart after contraction

• The total blood volume in the body

• The resistance the heart must overcome to eject blood

• The filling of the heart with blood before contraction

How does the body attempt to maintain blood pressure during hypovolemic shock?

• By constricting blood vessels

• By decreasing cardiac output

• By dilating blood vessels

• By increasing heart rate

What is the role of baroreceptors in hypovolemic shock?

• To dilate blood vessels

• To decrease heart rate

• To assess blood pressure

• To increase blood volume

Which of the following is NOT a cause of fluid loss leading to hypovolemic shock?

• Severe diarrhea

• Excessive vomiting

• Internal bleeding

• High protein diet

What symptom is commonly associated with hypovolemic shock due to blood being diverted from the skin?

• Increased sweating

• Warm, flushed skin

• Cool, clammy skin

• Reddened skin

What is a common symptom of hypovolemic shock related to blood loss?

• Cyanosis

• Hyperpigmentation

• Jaundice

• Conjunctival pallor

Which lab test is used to assess tissue oxygenation in hypovolemic shock?

• Electrolyte panel

• Serum lactate

• Complete blood count (CBC)

• Liver function test

What is the purpose of giving IV fluids in the treatment of hypovolemic shock?

• To increase heart rate

• To reduce blood pressure

• To decrease cardiac output

• To replete blood volume

Which of the following is a treatment option for a patient with low blood protein in hypovolemic shock?

• Albumin administration

• Blood transfusion

• Diuretic therapy

• Antibiotic treatment
