A patient is diagnosed with left ear unilateral sensorineural hearing loss. During the performance of the Weber test, the nurse expects lateralization of the sound/vibration to the:

Left temporal bone
Both ears equally
Right ear
Left ear
The Correct Answer is C
Choice a reason:
The left temporal bone would be the expected site of lateralization for sound in a Weber test if the patient had conductive hearing loss in the left ear. However, with unilateral sensorineural hearing loss, the sound typically lateralizes to the opposite ear, which is the ear with better hearing.
Choice b reason:
Lateralization to both ears equally during the Weber test would suggest either normal hearing or symmetrical hearing loss. In the case of unilateral sensorineural hearing loss, the sound is not perceived as equal in both ears because the affected ear does not hear as well as the unaffected ear.
Choice c reason:
In a patient with unilateral sensorineural hearing loss in the left ear, the Weber test will lateralize to the right ear, which is the ear with normal hearing. This occurs because the inner ear on the affected side is not able to transmit the sound as effectively as the unaffected side, making the sound seem louder in the ear with better hearing.
Choice d reason:
Lateralization to the left ear in the Weber test would indicate conductive hearing loss in the left ear, not sensorineural hearing loss. In sensorineural hearing loss, the sound vibrates to the ear with better cochlear function, which would be the right ear in this case.

Correct Answer is C
Explanation
Choice A reason:
Tachycardia, or an abnormally rapid heart rate, is not a typical finding in myxedema. Myxedema is associated with hypothyroidism, which usually presents with bradycardia, or a slower than normal heart rate, due to the decreased metabolic demands on the body.
Choice B reason:
Diarrhea is not commonly associated with myxedema. Instead, patients with hypothyroidism and myxedema often experience constipation due to slowed gastrointestinal motility.
Choice C reason:
Facial edema, particularly around the eyes, is a classic sign of myxedema. Myxedema is a severe form of hypothyroidism that can cause mucopolysaccharide deposition in the skin, leading to non-pitting edema. This can be particularly noticeable in the face and periorbital area.
Choice D reason:
Heat intolerance is more commonly associated with hyperthyroidism, not hypothyroidism. Patients with myxedema typically have cold intolerance due to a decrease in basal metabolic rate and reduced heat production.
Correct Answer is B
Explanation
Choice A reason:
Reddened intact skin is typically associated with a stage 1 pressure ulcer, where the skin is not yet broken but shows signs of redness. This stage indicates that the skin is under pressure and may be at risk for further breakdown if the pressure is not relieved.
Choice B reason:
A stage 3 pressure ulcer involves full-thickness skin loss that extends into the subcutaneous tissue layer but does not involve underlying muscle or bone. The ulcer presents as a deep crater, and there may be slough or eschar present. It is important to manage these ulcers carefully to prevent further deterioration and complications such as infection.
Choice C reason:
Skin loss involving up to the dermis layer is characteristic of a stage 2 pressure ulcer. In this stage, the epidermis and part of the dermis are lost, creating a shallow open wound or blister. This stage is less severe than stage 3 and requires different management strategies to promote healing and prevent progression.
Choice D reason:
Exposed bone is indicative of a stage 4 pressure ulcer, which is the most severe stage. It involves full-thickness skin loss with extensive destruction, possibly including muscle, tendon, or bone exposure. These ulcers are at high risk for serious infections, including osteomyelitis, and require aggressive medical and surgical intervention to heal.
