Question 1

When a staff member asks how erythrocytes can carry oxygen, the nurse should describe which of the following properties that allow erythrocytes to function as gas carriers? (Select all that apply.)
A) Biconcavity
B) Reversible deformability
C) Undergoes mitotic division
D) Presence of many mitochondria
E) Presence of a nucleus

Accepted Answer

Erythrocytes have a biconcave shape that increases their surface area for gas exchange and reversible deformability that allows them to change shape to pass through small capillaries. They do not undergo mitotic division, lack mitochondria, and do not have a nucleus.

Question 2

Fibrinolysis is mediated by:
A) heparin.
B) fibrinogen.
C) plasmin.
D) albumin.

Accepted Answer

Fibrinolysis is the process of breaking down fibrin in blood clots, and it is primarily mediated by plasmin, an enzyme that degrades fibrin.

Question 3

A nurse is caring for an elderly patient.Which of the following are true regarding the hematologic system and aging? (Select all that apply.)
A) Total serum iron is decreased.
B) Total iron-binding capacity is decreased.
C) Intestinal iron absorption is decreased.
D) Lymphocyte function is unchanged.
E) Platelet aggregation is unchanged.

Accepted Answer

The answer of A nurse is caring for an elderly...

Question 4

A nurse is caring for a patient who cannot clot.Which end product of the clotting cascade is this patient unable to make?
A) Collagen
B) Fibrinogen
C) Thrombin
D) Fibrin

Accepted Answer

The end product of the clotting cascade is fibrin, which forms a mesh that helps to stabilize the blood clot. If a patient cannot clot, they are unable to produce fibrin.
