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.

Did you know?

The use of salicylates dates back 2,500 years to Hippocrates’s recommendation of willow bark (from which a salicylate is derived) as an aid to the pains of childbirth. However, overdosage of salicylates can harm body fluids, electrolytes, the CNS, the GI tract, the ears, the lungs, the blood, the liver, and the kidneys and cause coma or death.

Did you know?

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).

Stroke kills people from all ethnic backgrounds, but the people at highest risk for fatal strokes are: black men, black women, Asian men, white men, and white women.

The Babylonians wrote numbers in a system that used 60 as the base value rather than the number 10. They did not have a symbol for "zero."
