The patient has a diagnosis of atherosclerosis. When a branch of the coronary artery becomes completely blocked, what event will the nurse expect to occur?

A) Heart failure
B) Arrhythmia
C) Myocardial infarction
D) Hypertension

Question 2

The post-anesthesia care unit nurse is serving a patient after a right knee arthroscopy. As the patient begins to wake up from anesthesia, the nurse assesses rigidity, involuntary movements, hyperthermia, and tachycardia.

What would the nurse suspect is causing these effects? A) Neuroleptic malignant syndrome
B) Parkinson-like syndrome
C) Malignant tachycardia
D) Anaphylactic shock

Answer to Question 1

C
Feedback:
The blood supply is most frequently altered, however, when the coronary vessels narrow and do not respond to stimuli to dilate and deliver more blood. This happens in atherosclerosis or coronary artery disease. The end result of this narrowing can be total blockage of a coronary artery, leading to hypoxia and eventual death of the cells that depend on that vessel for oxygen. This is called myocardial infarction (MI); as of 2010, it is the leading cause of death in the United States. An arrhythmia is an alteration in the conduction system. Heart failure is caused by ineffective pumping action of the heart muscle. Hypertension is an increase in blood pressure.

Answer to Question 2

A
Feedback:
Neuroleptic malignant syndrome is a generalized syndrome that includes extrapyramidal symptoms such as slowed reflexes, rigidity, involuntary movements; hyperthermia; autonomic disturbances (e.g., hypertension, fast heart rate); fever may be noted as well. This is most often seen after administering general anesthesia or drugs with central nervous system (CNS) effects. This syndrome was once known as malignant hyperthermia. These symptoms are not consistent with Parkinson-like syndrome or anaphylactic shock. Malignant tachycardia is a distracter.
