An assessment of a 23-year-old patient reveals the following: an auricle that is tender and reddish blue in colour and has small vesicles. What additional information would the nurse need to know?

Correct Answer: B

Rationale: The correct answer is B: Any recent drainage from the ear. This is crucial because drainage could indicate an infection or other underlying issue causing the auricle symptoms. Hearing changes (option A) may not be directly related to the auricle findings. Recent trauma (option C) would be more evident on inspection. Prolonged cold exposure (option D) is less likely to cause the described symptoms.

Correct Answer: A

Rationale: The correct answer is A: Red and bulging. In otitis media, the tympanic membrane becomes red and bulging due to inflammation and fluid accumulation. This is an early sign as it indicates increased pressure within the middle ear. Choice B (Hypomobility) is incorrect because it refers to decreased movement of the tympanic membrane, which is not specific to otitis media. Choice C (Retraction with landmarks clearly visible) is incorrect as it suggests the tympanic membrane is pulled inward, which is more indicative of otitis media with effusion rather than acute otitis media. Choice D (Flat, slightly pulled in at the center, and moves with insufflation) is incorrect as it describes a normal or retracted tympanic membrane rather than the characteristic red and bulging appearance seen in otitis media.

Correct Answer: D

Rationale: The presence of black and white dots on the tympanic membrane and ear canal wall during an otoscopic examination suggests a yeast or fungal infection. This is because yeast or fungal infections commonly present as white or black dots in the ear canal. Malignancy would typically manifest as abnormal growths or masses, not dots. Viral infections usually do not present as specific dots on the tympanic membrane. Blood in the middle ear would appear as red or pinkish fluid behind the eardrum, not as black and white dots. Therefore, the correct answer is D: Yeast or fungal infection.

Correct Answer: B

Rationale: The correct answer is B: filter out dust and bacteria. The ciliated mucous membrane in the nose traps dust and bacteria present in the inhaled air through the mucus layer and then moves them towards the throat to be swallowed or expelled. This helps in protecting the respiratory system from harmful particles. Choice A is incorrect as the warming of inhaled air is primarily done by the nasal passages and sinuses, not the ciliated mucous membrane. Choice C is incorrect because the filtering of coarse particles is also done by the nasal hairs and the mucous membrane working together, not just the ciliated mucous membrane alone. Choice D is incorrect as the movement of air through the nares is mainly controlled by the size of the nostrils and is not the primary function of the ciliated mucous membrane.

Correct Answer: A

Rationale: The correct answer is A: parotid gland. This gland is located in the cheek in front of the ear. It is the largest salivary gland in the human body. The parotid gland secretes saliva into the mouth through Stenson's duct. The other choices are incorrect because Stenson's gland does not exist, the sublingual gland is located under the tongue, and the submandibular gland is located under the mandible. Therefore, the parotid gland is the only gland that fits the description given in the question.
