The nurse in the telemetry unit explains two nonpharmacological treatments such as ___________, or ___________, can be used to treat dysrhythmias.
A) ECG; pacemaker
B) Cardioversion; defibrillation
C) Aspirin; Plavix
D) Exercise; stress test โโB) Cardioversion; defibrillation
The more serious types of dysrhythmias are corrected through electrical shock of the heart, a treatment called elective cardioversion, or defibrillation.
The client is scheduled for implantable cardioverter defibrillators (ICD) for treatment of a dysrhythmia. The nurse explains that the action of this procedure is to:
A) Trigger electrical impulses to the heart.
B) Take over SA node function.
C) Block AV node transmission of impulses.
D) Increase ventricular conduction. โโA) Trigger electrical impulses to the heart.
The nurse recognizes the action of beta blockers for treatment of dysrhythmias is:
A) Positive inotropic effect.
B) Negative inotropic effect.
C) Positive chronotropic effect.
D) Negative chronotropic effect. โโD) Negative chronotropic effect.
Beta blockers slow the heart rate (negative chronotropic effect) and decrease conduction velocity through the AV node.
A client with a diagnosis of cardiac dysrhythmias and a history of type I diabetes mellitus is placed on propranolol therapy. The client asks the nurse if the drug will affect insulin needs. The best response by the nurse would be that:
A) The drug will have no effect on insulin needs.
B) The drug might cause hypoglycemia.
C) The drug could cause hyperglycemia.
A) Heart rate.
B) Blood pressure.
D) Glucose.
C) Potassium. โโA) Heart rate.
Rationale: Studies show lack of drug-metabolizing enzyme (mephenytoin hydroxylase) causes Asians to metabolize propranolol more quickly than do Caucasians. The nurse should assess for high early buildup and overdose.
When planning care for a client receiving treatment for cardiac dysrhythmias, an appropriate client outcome would be:
A) The client will avoid use of caffeine during therapy.
B) The client will maintain heart rate below 60 beats per minute.
C) The client will limit fluid intake to 1000 ml/day.
D) The client will limit cigarettes to 15/day. โโA) The client will avoid use of caffeine during
therapy.
Rationale: Causes of dysrhythmias include electrolyte imbalance, hyperthyroidism, anxiety, caffeine ingestion, and tobacco use. The client should be taught to avoid caffeine and tobacco.

When assessing a client for an abdominal aortic aneurysm, which area of the abdomen is most commonly palpated?
A) Right upper quadrant
B) Directly over the umbilicus
C) Middle lower abdomen to the left of the midline
D) Midline lower abdomen to the right of the midline โโC) Middle lower abdomen to the left
of the midline
Which of the following conditions is linked to more than 50% of clients with abdominal aortic aneurysms?
C) Severe lower back pain, decreased BP, decreased RBC, decreased WBC
D) Intermittent lower back pain, decreased BP, decreased RBC, increased WBC โโB) Severe
lower back pain, decreased BP, decreased RBC, increased WBC
Severe lower back pain indicates an aneurysm rupture, secondary to pressure being applied within the abdominal cavity. When rupture occurs, the pain is constant because it can't be alleviated until the aneurysm is repaired. Blood pressure decreases due to the loss of blood. After the aneurysm ruptures, the vasculature is interrupted and blood volume is lost, so blood pressure wouldn't increase. For the same reason, the RBC count is decreased - not increase. The WBC count increases as cells migrate to the site of injury.
A client is admitted with suspected abdominal aortic aneurysm (AAA). A common complaint of the client with an abdominal aortic aneurysm is:
A) Loss of sensation in the lower extremities
B) Back pain that lessens when standing
C) Decreased urinary output

B) Putting several warm blankets on her
C) Monitoring her hourly urine output
D) Assessing her VS especially her RR โโD) Assessing her VS especially her RR

B) The patient will be admitted to the day surgery unit for sclerotherapy.
C) The patient will be admitted to the surgical unit and resection will be scheduled.
D) The patient will be discharged home to follow-up with his cardiologist in 24 hours. โโC)
The patient will be admitted to the surgical unit and resection will be scheduled.
A client with a diagnosis of angina pectoris is hospitalized for an angioplasty.
