New-onset atrial fibrillation can be serious for which of the following reasons?
 
  a. It increases the risk of stroke and pulmonary embolism from atrial clots.
  b. It increases the patient's risk of deep venous thrombosis.
  c. It may increase cardiac output to dangerous levels.
  d. It indicates that the patient is about to have an MI.

Question 2

The patient is a gravida 6, para 1
 
  She is admitted after a cesarean section after an amniotic embolus. Her heart rate (HR) is more than 150 beats/min with a systolic BP less than 80 mm Hg. Her temperature is 38 C, and her condition has caused her to develop prerenal azotemia. The patient was fluid resuscitated through a double-lumen catheter, which was placed into her right femoral access, and started on vasopressors with a fair response (BP, 80/50 mm Hg; HR, 122 beats/min). Because of her diagnosis and a concern regarding fulminating sepsis, the patient was begun on CVVH. Identify three complications of CVVH therapy.
 
  a. Fat emboli, increased ultrafiltration, and hypertension
  b. Hyperthermia, overhydration, and power surge
  c. Air embolism, decreased inflow pressure, and electrolyte imbalance
  d. Blood loss, decreased outflow resistance, and acidbase imbalance

Answer to Question 1

A
In atrial fibrillation the atria do not contract normally; they quiver. This increases the chance of the blood clotting in the atria because of a lack of complete emptying of the atria. These clots can break free and cause embolic strokes and pulmonary emboli. Atrial fibrillation does not indicate impending myocardial infarction or an increased risk of deep venous thrombosis. Atrial fibrillation decreases cardiac output from the loss of atrial kick.

Answer to Question 2

C
Air embolism, decreased inflow pressure, electrolyte imbalances, blood leaks, access failure, and clotted hemofilter are just a few complications that can occur with continuous venovenous hemodialysis.
