Example Question #1261 : Nclex
The nurse cares for a patient in the stroke unit. The physician has ordered thrombolytic therapy for this patient. The nurse knows that the patient cannot receive thrombolytic medication if which of these is true?
The patient takes propranolol every day.
The patient takes ibuprofen every day.
The patient was pregnant three months ago.
The patient had knee replacement surgery two weeks ago.
The patient has a history of cardiac dysrhythmias.
The patient had knee replacement surgery two weeks ago.
Thrombolytic therapy is commonly given to patients who have strokes to dissolve clots. This therapy is contraindicated in people who have recently had surgery due to the risk for hemorrhage. It is also contraindicated in currently pregnant women. Ibuprofen and beta blockers are not contraindications to thrombolytic therapy. Cardiac dysrhythmias are also not contraindicated with thrombolytic therapy.
Example Question #1262 : Nclex
An EKG monitor reveals a patient is in ventricular fibrillation. He is subsequently provided the appropriate management and is converted to normal sinus rhythm. What is the mechanism of this management?
Electrical shock to speed up heart rate
Pharmacologic therapy to slow conduction at the atrioventricular node
Pharmacologic therapy to block the release of angiotensin
Pharmacologic therapy to slow conduction at the sinoatrial node
Electrical shock to restart the electrical conductivity of the heart
Electrical shock to restart the electrical conductivity of the heart
Ventricular fibrillation is a potentially lethal rhythm. It is treated via defibrillation. This is an electrical shock that temporarily stops the heart in an attempt to have the natural pacemaker rhythm of the heart take over. Electrical therapy via defibrillation is the appropriate management of ventricular fibrillation.
