Correct Answer: C

Rationale: The correct answer is C: bruising on the buccal mucosa or gums. This is the most relevant choice as it is a common sign of physical abuse in children. Bruising in unusual places or patterns, such as the mouth, should raise suspicion. Swollen, red tonsils (A) are more likely related to infection rather than abuse. Ulcerations on the hard palate (B) can also be due to various non-abuse related reasons. Small yellow papules along the hard palate (D) are typically harmless and not indicative of abuse. It is crucial for the nurse to recognize signs of potential abuse and take appropriate action to protect the child.

Correct Answer: D

Rationale: Clubbing of the fingernails is characterized by an increased angle between the nail base and the nail plate (usually 180 degrees or greater) and a spongy texture at the nail base. This is due to underlying tissue changes associated with conditions like lung disease. Choice D is correct as it accurately describes the characteristic findings of clubbing. Choices A, B, and C do not align with clubbing features. Choice A describes tenderness and firmness, not sponginess and increased angle. Choice B mentions a convex profile and ridges, which are not specific to clubbing. Choice C includes an angle of 150 degrees, which is less than the typical angle seen in clubbing.

Correct Answer: A

Rationale: The correct answer is A: this is most likely serous otitis media. In a child with chronic ear infections, amber-yellow tympanic membrane color and air bubbles suggest fluid accumulation behind the eardrum, characteristic of serous otitis media. The occasional hearing loss and popping sound with swallowing are also common symptoms. Serous otitis media is a non-infectious condition caused by Eustachian tube dysfunction. Choice B: Acute purulent otitis media presents with more severe symptoms like fever and severe ear pain, which are not mentioned in the case. Choice C: Cholesteatoma is a more serious condition characterized by a cyst-like growth in the middle ear, not just fluid accumulation as seen in this case. Choice D: Perforation typically presents with a visible hole in the eardrum and is not consistent with the findings of fluid and air bubbles in this case.

Correct Answer: B

Rationale: The correct answer is B: Basal cell carcinoma. The clinical presentation of a papule with rounded, pearly borders, central red ulcer, slow growth, and location on the nose is highly indicative of basal cell carcinoma. Basal cell carcinoma commonly presents with these characteristics and is the most common type of skin cancer. It is locally invasive but rarely metastasizes. A: Acne is a common skin condition characterized by comedones, papules, and pustules, not typically presenting with the described features. C: Malignant melanoma usually presents as an asymmetric, irregularly bordered, multicolored lesion with rapid growth and potential for metastasis. D: Squamous cell carcinoma typically presents as a scaly, crusted lesion with potential for metastasis, not showing the described features.

Correct Answer: C

Rationale: The correct answer is C: Dysphagia. In a stroke patient with right-sided facial drooping, dysphagia is highly likely due to the involvement of the facial nerve, leading to difficulty swallowing. Epistaxis (A) is nosebleeds, agenesis (B) is the absence of a body part, and xerostomia (D) is dry mouth, which are not directly related to facial drooping in stroke patients. Dysphagia is a common complication post-stroke due to impaired muscle control, making it the most likely concern for the nurse to suspect in this case.
