Which of the following patients who presented to a walk-in medical clinic is most likely to be diagnosed with a rhinosinusitis rather than a common cold?

A)
A man complaining of general fatigue, a headache, and facial pain with a temperature of 100.9 F
B)
A woman presenting with malaise, lethargy, and copious nasal secretions
C)
A man with a dry, stuffy nasopharynx, a sore throat, and temperature of 98.9 F
D)
A woman complaining of generalized aches and who has a hoarse voice and reddened, painful upper airways

Question 2

An ECG technician is placing leads on a patient who has presented to the emergency department with a sudden onset of chest pain.

The technician would recognize which of the following facts about the placement of leads and the achievement of a clinically accurate ECG?
A)
The electrical potential recorded by a lead on an extremity will vary significantly depending on where the lead is placed on the extremity.
B)
The chest leads measure electrical activity on the horizontal plane, while limb leads measure it on the vertical plane.
C)
Limb leads measure the electrical activity of the heart indirectly through the activity of adjacent skeletal muscle.
D)
A total of 12 chest leads are necessary to attain the most accurate ECG.

Answer to Question 1

Ans:
A

Feedback:

Fever and facial pain are more commonly associated with rhinosinusitis rather than the common cold. The other noted symptoms are indicative of the common cold rather than rhinosinusitis.

Answer to Question 2

Ans:
B

Feedback:

A complete ECG is obtained by combining data from chest leads, which measure activity on the horizontal plane, and limb leads, corresponding to the vertical or frontal plane. The electrical potential recorded by a lead on an extremity should not vary significantly depending on where the lead is placed on the extremity, and limb leads do not measure electrical activity by way of skeletal muscle activity. A total of 12 leads, only six of which are on the chest, are necessary for a complete ECG.
