The nurse plans to assess the client's hearing.
What action should the nurse take when performing the Weber's test?
The nurse will understand the unaffected ear will show lateralization to the Weber's test.
Place the activated tuning fork to the mid skull and ask if the patient can hear it louder in either ear.
Place the activated tuning fork to the patient's mastoid bone first then place over air.
Place the activated tuning fork to the client's ear over the mastoid bone then activate it again over the air.
The Correct Answer is B
Choice A rationale
Lateralization to the unaffected ear in Weber's test actually indicates sensorineural hearing loss in the affected ear. This choice is incorrect as it doesn’t describe the correct procedure for the test.
Choice B rationale
The Weber's test involves placing an activated tuning fork in the midline of the skull and asking the patient if the sound is heard more loudly in either ear. This helps determine if there is lateralization, which is key in diagnosing the type of hearing loss. Thus, this is the correct procedure for the test.
Choice C rationale
Placing the tuning fork on the mastoid bone and then over air is actually part of the Rinne test, not the Weber test. This choice is, therefore, incorrect for the Weber test.
Choice D rationale
Similar to Choice C, this process describes the Rinne test, which compares air conduction and bone conduction of sound. This is not the correct method for performing Weber’s test.

Correct Answer is A
Explanation
Choice A rationale
Pallor refers to the pale appearance of the skin due to decreased blood flow or decreased hemoglobin levels. It is often seen in conditions such as anemia, where there is a reduced number of red blood cells or hemoglobin, leading to a lack of the red-pink tones normally present in healthy skin.
Choice B rationale
Cyanosis refers to a bluish discoloration of the skin and mucous membranes due to inadequate oxygenation of the blood. It is often seen in respiratory or cardiovascular conditions where there is a decrease in oxygen levels. Cyanosis does not describe the absence of red-pink tones from decreased hemoglobin.
Choice C rationale
Jaundice refers to a yellow discoloration of the skin and eyes due to elevated levels of bilirubin in the blood. It is often seen in liver conditions or hemolysis. Jaundice is not related to decreased hemoglobin levels or the absence of red-pink tones in the skin.
Choice D rationale
Erythema refers to redness of the skin caused by increased blood flow to the capillaries in the dermis. It is often associated with inflammation, infection, or skin irritation. Erythema indicates increased blood flow, not decreased hemoglobin levels.
Correct Answer is D
Explanation
Choice A rationale
The abducens cranial nerve (CN VI) controls the lateral rectus muscle of the eye, which is responsible for outward movement. It is not assessed using the Snellen visual acuity chart. The function of this nerve is tested through the evaluation of lateral eye movements.
Choice B rationale
The optic cranial nerve (CN II) is responsible for vision, including visual acuity and visual fields. It is assessed using the Snellen visual acuity chart to determine how well a person can see at various distances. This test evaluates the clarity and sharpness of vision, making CN II the correct answer.
Choice C rationale
The trochlear cranial nerve (CN IV) controls the superior oblique muscle, which helps with downward and inward eye movements. It is not assessed using the Snellen visual acuity chart but rather through the evaluation of eye movements and alignment.
Choice D rationale
The oculomotor cranial nerve (CN III) controls most of the eye's movements, including those of the superior, inferior, and medial rectus muscles, as well as the inferior oblique muscle. It is also responsible for controlling the pupil's response to light. The Snellen visual acuity chart does not assess the function of CN III, as it focuses on visual clarity and acuity.
