Correct Answer: A

Rationale: Step-by-step rationale for why choice A (Tachycardia) is correct: 1. Hyperthyroidism leads to increased production of thyroid hormones. 2. Thyroid hormones can increase metabolic rate and heart rate. 3. Tachycardia is a common symptom of hyperthyroidism due to increased metabolic demand. 4. Therefore, the nurse would most likely find tachycardia on examination in a patient with hyperthyroidism. Summary of why other choices are incorrect: B: Constipation - Constipation is more commonly associated with hypothyroidism, not hyperthyroidism. C: Rapid dyspnea - Dyspnea (shortness of breath) is not a typical symptom of hyperthyroidism. D: Atrophied, nodular thyroid - Hyperthyroidism often presents with an enlarged, not atrophied, thyroid gland due to overactivity. Nodules may be present in conditions like thyroid cancer, but not specific to hyper

Correct Answer: B

Rationale: The correct answer is B: This is a bifid uvula, which is a common occurrence in some Aboriginal groups. 1. A bifid uvula is a condition where the uvula is split or divided, which is a common variation seen in some Aboriginal populations. 2. Cleft palate is a different condition involving a gap in the roof of the mouth, not specifically related to Aboriginal people. 3. Uvular injury is not a common cause of a split uvula in children, so reporting to authorities is unnecessary. 4. Torus palatinus is a bony growth on the roof of the mouth and not related to a split uvula or specific to Aboriginal populations.

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: D

Rationale: The correct answer is D because floaters are a common and typically benign phenomenon caused by condensed vitreous fibers in the eye. A nurse should educate the patient that floaters are usually not significant and do not require immediate intervention. Option A is incorrect because counting the number of floaters is unnecessary. Option B is incorrect because presuming glaucoma without proper assessment is inappropriate. Option C is incorrect because seeing occasional floaters is a common and normal occurrence in many individuals.

Correct Answer: C

Rationale: The correct answer is C: Tilt the child's head slightly toward the examiner. This position straightens the ear canal, facilitating visualization. Pulling the pinna down (A) can cause discomfort and obstruct the view. Pulling the pinna up and back (B) is incorrect for a child under 3 years old as it straightens the ear canal in adults. Having the child touch his chin to his chest (D) is unnecessary and may lead to improper examination positioning.
