Results from which two procedures complement each other in the preoperative evaluation of the carotid arteries?
 
  a. Ultrasound Doppler and magnetic resonance angiography
  b. Conventional angiography and evoked potential
  c. CT and magnetic resonance angiography
  d. Transcranial Doppler and extracranial Doppler

Question 2

Which of the following statements are true regarding rotational therapy? (Select all that apply.)
 
  a. Continuous lateral rotation therapy (CLRT) can be effective for improving oxygenation if used for at least 18 hours/day.
  b. Kinetic therapy can decrease the incidence of ventilator-acquired pneumonia in neurologic and postoperative patients.
  c. Use of rotational therapy eliminates the need for other pressure ulcer prevention strategies.
  d. CLRT helps avoid hemodynamic instability secondary to the continuous, gentle turning of the patient.
  e. CLRT has minimal pulmonary benefits for critically ill patients.

Answer to Question 1

A
Magnetic resonance angiography of the carotid arteries has become an established complement to preoperative ultrasound evaluation. It helps determine the area of salvageable tissue (or penumbra) after acute stroke and head injury.

Answer to Question 2

A, B, E
Studies have found that to achieve benefits with CLRT or kinetic therapy, rotation must be aggressive, and the patient must be at least 40 degrees per side, with a total arc of at least 80 degrees for at least 18 hours a day. Kinetic therapy has been shown to decrease the incidence of ventilator-acquired pneumonia, particularly in neurologic and postoperative patients. Complications of the procedure include dislodgment or obstruction of tubes, drains, and lines; hemodynamic instability; and pressure ulcers. Lateral rotation does not replace manual repositioning to prevent pressure ulcers. CLRT has been shown to be of minimal pulmonary benefit for the critically ill patients.

Did you know?

The most common childhood diseases include croup, chickenpox, ear infections, flu, pneumonia, ringworm, respiratory syncytial virus, scabies, head lice, and asthma.

Did you know?

Giardia is one of the most common intestinal parasites worldwide, and infects up to 20% of the world population, mostly in poorer countries with inadequate sanitation. Infections are most common in children, though chronic Giardia is more common in adults.

Did you know?

As many as 28% of hospitalized patients requiring mechanical ventilators to help them breathe (for more than 48 hours) will develop ventilator-associated pneumonia. Current therapy involves intravenous antibiotics, but new antibiotics that can be inhaled (and more directly treat the infection) are being developed.

Did you know?

All adverse reactions are commonly charted in red ink in the patient's record and usually are noted on the front of the chart. Failure to follow correct documentation procedures may result in malpractice lawsuits.

Did you know?

Many people have small pouches in their colons that bulge outward through weak spots. Each pouch is called a diverticulum. About 10% of Americans older than age 40 years have diverticulosis, which, when the pouches become infected or inflamed, is called diverticulitis. The main cause of diverticular disease is a low-fiber diet.
