Question 66

Many chest x-rays taken in the progressive care unit are obtained with which of the following views, with the patient lying supine in bed?

Correct Answer: A
Correct answer: An anterior-posterior view
Many chest x-rays taken in the progressive care unit are obtained with an anterior-posterior (AP) view with the patient lying supine in bed.
Acutely ill patients are rarely able to tolerate the positioning requirements of a posterior-anterior (PA) chest x-ray.
With portable AP chest films, the x-ray machine is only 3 feet away from the patient, which results in greater distortion of chest images; this makes the AP chest x-ray less accurate than the PA method.
When viewing chest x-rays, it is important to know whether an AP or PA view was used to avoid misinterpretation of heart size as cardiomegaly.

Question 67

Of the following, which is the gold standard for detecting pulmonary embolism?

Correct Answer: A
Correct answer: Computed tomography of the pulmonary arteries (CTPAs)
The CTPA is the gold standard for detecting pulmonary embolism (PE). This is a minimally invasive test, requiring only a peripheral line through which to inject the contrast material. An embolus will appear as a dark filling defect on images obtained following injection of the contrast material in an otherwise bright white pulmonary artery that is filled with the contrast material.
CTPA has replaced pulmonary angiography, which is more invasive, in the diagnostic testing for PE.
Ventilation-perfusion scanning may also be used to diagnose PE, but it is a cumbersome test and is not the gold standard. MRI is also not the correct answer.

Question 70

Which of the following statements is true regarding communication with a ventilated patient?

Correct Answer: C
Correct answer: Before attempting to guess the needs of a nonvocal patient, provide them with an opportunity to use gestures to convey their needs Mechanically ventilated patients are unable to speak and communicate verbally due to the presence of a cuffed endotracheal tube or tracheostomy tube. One nonvocal communication method that can prove effective is the use of gestures. The use of this method is best suited for the patient who can move at least one hand, even if only slightly. Practitioners should use simple "yes" or "no" questions but should avoid playing "twenty questions" and should give patients the opportunity to use gestures to communicate before attempting to guess what they need.
There are several methods to augment communication with patients who have artificial airways and with those who are mechanically ventilated; the best way to communicate with these patients is still unknown. Once the most successful methods of communication have been identified with a particular patient, these methods should be added to the plan of care. Continuity among caregivers in their approach to communication improves the quality of care and patient satisfaction.
