Pacemaker

Answer and Explanation

A.   Pulseless ventricular tachycardia requires immediate defibrillation to restore a perfusing rhythm.
B.   Antiarrhythmic medications are not typically effective for pulseless ventricular tachycardia as the heart is not effectively pumping blood.

Correct Answer is ["C","D","E"]

Explanation

A. Digoxin typically decreases the heart rate by increasing vagal tone and reducing conduction through the atrioventricular node.
B. Digoxin may have minimal effects on blood pressure, primarily by improving cardiac output in patients with heart failure, but its primary action is on cardiac contractility and rhythm.
C. Digoxin has a negative chronotropic effect, meaning it slows the heart rate by increasing parasympathetic tone and decreasing conduction through the atrioventricular node.
D. Digoxin has a positive inotropic effect, meaning it increases the force of cardiac contractions, which can be beneficial in patients with heart failure.
E. Digoxin can suppress ectopic beats (abnormal heart rhythms originating outside the sinoatrial node) by slowing conduction through the atrioventricular node and enhancing vagal tone

A. Use contact precautions. B. Administer ibuprofen prior to assisting with ADLS C. Measure rectal temperature every 4 hr. D. Administer a stool softener.

Correct Answer is D

Explanation

A. Leukemia itself doesn't necessitate contact precautions unless there are other specific infectious concerns, which are not mentioned in this scenario.
B. Ibuprofen is contraindicated in patients with low platelet counts due to the risk of bleeding. Therefore, administering ibuprofen would exacerbate the risk of bleeding in this patient.
C. Invasive procedures like rectal temperature measurements should be avoided in patients with low platelet counts due to the risk of bleeding. Thus, this intervention increases the risk of harm to the patient.
D. Patients with low platelet counts are at risk for bleeding, including gastrointestinal bleeding. Administering a stool softener can help prevent straining during bowel movements, reducing the risk of bleeding and promoting patient comfort and safety.
