A nurse is preparing to inspect the tympanic membrane of an adult client. Which action demonstrates correct technique?

Insert the otoscope deeply into the ear canal before visualization.

Pull the auricle downward and backward before inserting the otoscope.

Pull the auricle upward and backward before inserting the otoscope.

Ask the client to tilt the head forward during the assessment.

Answer and Explanation

The Correct Answer is C

Rationale:

A. Inserting the otoscope deeply into the ear canal can cause discomfort, pain, or injury to the client’s ear. Proper technique requires gentle insertion just far enough to visualize the tympanic membrane without causing trauma.

B. Pulling the auricle downward and backward is appropriate for children under 3 years old, not adults. Using this technique on an adult may make visualization difficult and does not align with standard adult assessment guidelines.

C. Pulling the auricle upward and backward straightens the ear canal in adults, allowing proper visualization of the tympanic membrane. This technique reduces obstruction from the canal’s natural curve and facilitates accurate assessment while minimizing discomfort.

D. Asking the client to tilt the head forward is not necessary for otoscopic examination. The client should remain seated with the head in a neutral position while the nurse gently straightens the canal with the correct auricle maneuver. Tilting the head forward does not improve visualization.

Correct Answer is D

Explanation

Rationale:
A. Glaucoma is characterized by increased intraocular pressure that can lead to optic nerve damage and gradual peripheral vision loss. The lens remains clear, so a cloudy or opaque lens is not typical of glaucoma.

B. This condition affects the macula, the central portion of the retina, leading to loss of central vision. The lens is not affected, so cloudy or opaque areas over the lens do not occur with macular degeneration.

C. This is a complication of diabetes that damages the retinal blood vessels, causing hemorrhages, exudates, and vision loss. It affects the retina, not the lens, so a cloudy or opaque lens is not a characteristic finding.

D. Cataracts involve clouding of the lens, which obstructs light from passing clearly to the retina. This cloudiness is the hallmark sign of cataracts and can lead to blurred vision, glare, and difficulty seeing in low light. The description of a cloudy, opaque area over the lens directly indicates a cataract.

A. A B. B C. C D. D

Correct Answer is C

Explanation

Rationale:
A. The femoral triangle, located in the upper thigh near the inguinal ligament, is where the femoral artery runs and is palpated for the femoral pulse. It does not provide information about distal lower extremity circulation, so it is not used to assess the posterior tibial pulse.

B. The knee area corresponds to the popliteal artery, which is palpated behind the knee for the popliteal pulse. This site is deeper and more difficult to palpate, and it does not reflect circulation in the foot or ankle.

C. The posterior tibial pulse is located on the postero-medial aspect of the lower third of the leg, just behind the medial malleolus. Palpating here allows assessment of arterial blood flow to the foot and helps detect peripheral arterial disease in the lower extremities.

D. The area between the second and third toes is where the dorsalis pedis artery runs. Palpating this site assesses the dorsalis pedis pulse, not the posterior tibial pulse, and evaluates a different part of foot circulation.
