Which of the following medications from a client's medication list would increase their surgical risk?

A.

Lisinopril

B.

Acetaminophen

C.

Aspirin

D.

Metoprolol

Answer and Explanation

The Correct Answer is C

A.    Lisinopril is an ACE inhibitor used to treat hypertension and heart failure. It can affect blood pressure regulation and might impact intraoperative and postoperative blood pressure control, but it is not generally associated with increased surgical bleeding risk.
B.    Acetaminophen is a pain reliever and antipyretic used for mild to moderate pain and fever. It does not have a significant impact on bleeding risk or interfere with clotting mechanisms. It is generally considered safe for use around the time of surgery.
C.    Aspirin is an antiplatelet medication that inhibits platelet aggregation and can increase the risk of bleeding. It affects blood clotting and can lead to excessive bleeding during and after surgery. It is often recommended to stop aspirin use several days before surgery to reduce this risk, unless specifically directed otherwise by the healthcare provider.
D.    Metoprolol is a beta-blocker used to manage hypertension and heart conditions. It is generally not associated with increased bleeding risk.

Correct Answer is A

Explanation

A. Alcohol can affect blood clotting mechanisms and increase the risk of bleeding. Chronic alcohol consumption is associated with liver dysfunction, which impairs the production of clotting factors, leading to an increased risk of bleeding during and after surgery.
B. Alcohol consumption does not decrease the risk of postoperative infection. In fact, alcohol use, especially if it’s chronic, can impair the immune system and delay wound healing, potentially increasing the risk of postoperative infections.
C. Alcohol does not enhance the effectiveness of anesthesia; rather, it can complicate anesthesia management. Alcohol can interact with anesthetic agents, potentially altering their effects, leading to unpredictable outcomes.
D. Alcohol does not reduce the risk of postoperative nausea and vomiting (PONV). In fact, alcohol use can exacerbate nausea and vomiting, particularly when combined with anesthetic agents.

Correct Answer is D

Explanation

A. Lymphocytes are a type of white blood cell that plays a crucial role in the immune system, specifically in the response to infections and in immune regulation. They do not have a role in the transport of oxygen in the blood.
B. Neutrophils are another type of white blood cell that is essential for fighting bacterial infections. They are part of the body's immune response but do not transport oxygen.
C. Platelets are small cell fragments that are crucial for blood clotting and wound repair. They do not have a role in oxygen transport.
D. Hemoglobin is the primary molecule responsible for transporting oxygen in the blood. It is a protein found in red blood cells (erythrocytes) that binds to oxygen in the lungs and releases it in tissues throughout the body. Hemoglobin carries the majority of oxygen in the bloodstream and is essential for effective oxygen transport and delivery.
