To assess the tympanic membrane mobility, which instrument is most appropriate for the nurse to use?
Audiometer
Ophthalmoscope
Pneumatic otoscope
Tuning fork
The Correct Answer is C
A. An audiometer is used to assess hearing ability and is not appropriate for examining the tympanic membrane.
B. An ophthalmoscope is used to examine the interior of the eye and cannot assess tympanic membrane mobility.
C. A pneumatic otoscope is specifically designed for examining the tympanic membrane and allows for assessment of its mobility by using air pressure.
D. A tuning fork is used to evaluate hearing and vibration sense, not tympanic membrane mobility.

Correct Answer is D
Explanation
A. Elevated blood pressure is not an indication of dehydration; dehydration is more likely to cause a drop in blood pressure due to decreased blood volume.
B. Dehydration typically does not cause a low body temperature; instead, it can lead to an elevated temperature as the body conserves water.
C. Jugular vein distention is associated with fluid overload or heart failure, not dehydration.
D. Skin tenting, where the skin remains elevated after being pinched, is a classic sign of dehydration due to reduced skin elasticity.
Correct Answer is A
Explanation
A. The carotid pulse should not be assessed bilaterally at the same time, as simultaneous palpation can lead to a decrease in heart rate or cause syncope due to stimulation of the carotid sinus.
B. The radial pulse can be assessed bilaterally without risk.
C. The brachial pulse can also be assessed bilaterally without concern.
D. The femoral pulse is typically assessed one side at a time, but there is no risk in palpating both femoral arteries simultaneously as there is with the carotid.
