The nurse preceptor is teaching a newly licensed nurse about blood flow through the heart.
The nurse preceptor knows teaching has been effective when the newly licensed nurse states that the upper chambers of the heart are:.
The thickest part of the heart.
Where blood leaves.
Where blood enters.
Called ventricles.
The Correct Answer is C
Choice A rationale:
The thickest part of the heart is not the upper chambers but the lower chambers, specifically the left ventricle. This is because it needs to pump blood to the entire body.
Choice B rationale:
Blood leaves the heart through the lower chambers, or ventricles, not the upper chambers.
Choice C rationale:
Blood enters the heart through the upper chambers, or atria. This is where deoxygenated blood from the body and oxygenated blood from the lungs first enter the heart.
Choice D rationale:
The term “ventricles” refers to the lower chambers of the heart, not the upper chambers.

Correct Answer is B
Explanation
Choice A rationale:
Checking for a positive Chvostek’s sign is not relevant. This sign is associated with hypocalcemia, not with the lab values provided.
Choice B rationale:
The nurse should request a potassium replacement. The normal range for potassium is 3.5-5.0 mEq/L. A level of 3.0 mEq/L is low, indicating hypokalemia.
Choice C rationale:
Administering glucagon IM is not appropriate. The glucose level is within the normal range (70-110 mg/dL), so there is no need for glucagon.
Choice D rationale:
Discontinuing the TPN infusion is not the first action. The nurse should address the abnormal lab value (low potassium) first.
Correct Answer is B
Explanation
Choice A rationale:
Placing the client in a modified Trendelenburg position is not the first action to take when managing a heavily bleeding wound.
Choice B rationale:
Applying direct pressure to the wound is the first action to take to control bleeding.
Choice C rationale:
Elevating the extremity can help control bleeding, but it is not the first action to take.
Choice D rationale:
Applying a tourniquet is a last resort when other methods of controlling bleeding have failed.
