Question 1
2 out of 2 points
When percussing, a dull tone is
... [Show More] expected to be heard over:
Response Feedback: Dull tones are expected over more dense areas such as the liver.
Question 2

The dorsal surface of the hand is most often used for the assessment of:
Response Feedback: The dorsal surface, or back of the hand, can best feel for warmth.
Question 3

A patient in the emergency department has a concussion to the head. You suspect the patient may also have a retinal hemorrhage. You are using the ophthalmoscope to examine the retina of this patient. Which aperture of the ophthalmoscope is most appropriate for this patient?
Response Feedback: The red-free filter permits recognition of hemorrhages. The grid estimates the size of lesions; the slit lamp examines the anterior eye and assesses the elevation of lesions; and the small aperture is used with small pupils. The strabismoscope is used for detecting strabismus.
Question 4
2 out of 2 points
The use of secondary, tangential lighting is most helpful in the detection of:
Response Feedback: Tangential lighting is used to cast shadows in order to best observe contours and variations in body surfaces. All of the other choices are best observed with direct lighting that does not cast shadows.
Question 5
2 out of 2 points
Tuning forks with a frequency of 500 to 1000 Hz are most commonly used to measure:
Response Feedback: Normal speech has a range of 300 to 3000 Hz; therefore, the 500- to 1000-Hz fork is most often used because it can estimate hearing loss in the range of normal speech.
Question 6
2 out of 2 points
Which patient is at the highest risk for the development of latex allergy?
Response Feedback: The patient who has had multiple procedures or surgeries has a higher exposure rate to rubber gloves and to equipment and supplies that contain latex and therefore is at a higher risk for developing an allergic response.
Question 7
2 out of 2 points
A variant of the percussion hammer is the neurologic hammer, which is equipped with which of the following?
Response Feedback: The neurologic hammer unscrews at the handle to reveal a soft brush and the knob on the head unscrews, to which is attached a sharp needle.
Question 8
2 out of 2 points
Transillumination functions on the principle that:
Response Feedback: Transillumination functions to differentiate between various media in a cavity. It can distinguish between air, fluid, and tissue. It consists of a strong light in the visible spectrum with a narrow beam.
Question 9
2 out of 2 points
Which statement is true regarding the relationship of physical characteristics and culture?
Response Feedback: Physical characteristics do not symbolize cultural groups; there is a difference between the two, and they are considered separately. Cultures are dynamic in their evolution.
Question 10
2 out of 2 points
A scale used to assess patients weight should be calibrated:
Response Feedback: Obtaining weight begins with a manual calibration of the scale before the patient stands on the scale. Electronic scales are automatically calibrated before each reading.
Question 11
2 out of 2 points
Which technique is commonly used to elicit tenderness arising from the liver, gallbladder, or kidneys?
Response Feedback: The fist percussion is a direct percussion technique used to elicit tenderness over organs such as the liver, gallbladder, or kidneys.
Question 12
2 out of 2 points
A rubber or plastic ring should be around the bell end-piece of a stethoscope to:
Response Feedback: The ring around the bell portion of the stethoscope functions to secure contact with body surfaces when placed lightly on the skin.
Question 13
2 out of 2 points
In terms of cultural communication differences, Americans are more likely to _____ than are other groups of patients.
Response Feedback: In the United States, individuals are very direct in conversation and come to the point quickly. They also tend to talk more loudly and to worry less about being overheard.
Question 14
2 out of 2 points
For a woman with a small vaginal opening, the examiner should use a _____ speculum.
Response Feedback: The Pederson speculum has blades that are as long as those of the Graves speculum but are both narrower and flatter and therefore more comfortable for women with small vaginal openings. Pediatric or nasal speculums would be too small for adult use. Plastic speculums are similar in uses to the metal counterparts.
Question 15
2 out of 2 points
During percussion, the downward snap of the striking fingers should originate from the:
Response Feedback: The dominant hand s middle finger strikes the stationary finger with a wrist motion and is lifted quickly off the striking surface.
Question 16
2 out of 2 points
You are auscultating a patient s chest. The sounds are not clear, and you are having difficulty distinguishing between respirations and heartbeats. What technique can you use to facilitate your assessment?
Response Feedback: If you are hearing everything at once, it is more difficult to distinguish different sounds. Try isolating each segment and listen to that segment intently, then move on to another segment. For example, listen only to breath sounds, then only to inspiratory breath sounds, then only expiratory breath sounds.
Question 17
2 out of 2 points
Expected normal percussion tones include:
Response Feedback: A normal lung produces resonance percussion tones while an empty stomach is expected to produce tympany. Dull percussion tones are heard over the liver.
Question 18
2 out of 2 points
During auscultation, you can limit your perceptual field best by:
Response Feedback: By closing your eyes, your sense of hearing becomes more acute and it increases your ability to isolate sounds.
Question 19
2 out of 2 points
Standard Precautions apply to all patients:
Response Feedback: Although all of the statements are true, the best answer is 4. Standard Precautions were developed with the intent of application in the care of all hospitalized patients; however, the standard has merit to be applied to all cases of patient care regardless of the environment in which care is delivered.
Question 20
