Understanding Colloids in Nursing

What is the primary function of colloids in the body?

• To decrease blood pressure

• To increase plasma volume

• To reduce heart rate

• To enhance oxygen transport

How do colloids increase plasma volume?

• By escaping the capillary walls

• By increasing blood cell count

• By pulling water into the intravascular space

• By reducing oncotic pressure

Which of the following is a natural type of colloid?

• Gelatin

• Hydroxyethyl starch

• Dextran

• Human albumin

What is a key difference between colloids and crystalloids?

• Crystalloids are more expensive

• Colloids stay longer in the intravascular space

• Crystalloids create oncotic pressure

• Colloids are small molecules

What should a nurse check before administering colloids?

• Patient's blood type

• Patient's allergies

• Patient's height

• Patient's age

Which of the following is a potential risk when administering colloids?

• Increased blood sugar

• Allergic reactions

• Improved digestion

• Decreased heart rate

What should be monitored to prevent fluid overload?

• Patient's weight and intake/output

• Patient's appetite

• Patient's hair growth

• Patient's skin color

What sound might indicate fluid volume overload in a patient?

• Normal heart sounds

• Crackles in the lungs

• High-pitched wheezing

• Silence in the lungs

What lab result might indicate a bleeding problem when administering colloids?

• Decreased blood glucose

• Increased PT/PTT results

• Normal platelet count

• Decreased cholesterol levels

What is a sign of an allergic reaction to colloids?

• Difficulty breathing

• Improved vision

• Increased energy

• Increased appetite
