health assessment practice questions

Correct Answer: B

Rationale: The correct answer is B: the lump is mobile and not hard. A cancerous thyroid nodule is typically fixed and hard, whereas a noncancerous nodule is more likely to be mobile and soft. This characteristic suggests it may be a benign condition such as a thyroid cyst rather than a malignant tumor. The other choices are incorrect because A: tenderness does not necessarily indicate benignity or malignancy, C: disappearance when smiling is more related to a salivary gland issue, and D: hardness and fixation are more indicative of a potentially cancerous nodule.

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: C

Rationale: The correct answer is C because as individuals age, there is a natural decrease in skin elasticity, subcutaneous fat, and moisture content in the skin. These factors contribute to the bones becoming more noticeable in the face. Choice A is incorrect because diets low in protein and high in carbohydrates do not directly cause enlargement of facial bones. Choice B is incorrect as the use of a specific moisturizer does not directly impact the visibility of facial bones. Choice D is incorrect because facial skin actually loses elasticity with age, leading to less taut skin and more prominent bones.

Correct Answer: C

Rationale: The correct answer is C because the frontal sinuses are indeed fairly well developed at birth. This is true as the frontal sinuses start developing around the age of 7-8 years but are present in a rudimentary form at birth. This is because the frontal bone grows rapidly in the first few years of life, allowing for the development of the frontal sinuses. Choice A is incorrect because the sphenoid sinuses are not at full size at birth; they continue to develop throughout childhood. Choice B is incorrect as the maxillary sinuses reach full size around the teenage years, not after puberty. Choice D is incorrect as the frontal sinuses are also present at birth, along with the maxillary and ethmoid sinuses.

Correct Answer: C

Rationale: The correct answer is C because stimulation of the sympathetic branch of the autonomic nervous system results in the elevation of the eyelid (ptosis) and dilation of the pupil (mydriasis). This is due to the action of the dilator pupillae muscle and the superior tarsal muscle. Pupillary constriction (choice A) is controlled by the parasympathetic branch via the sphincter pupillae muscle. Adjusting the eye for near vision (choice B) is controlled by the ciliary muscle, which is under parasympathetic control, not sympathetic. Contraction of the ciliary body (choice D) is also controlled by the parasympathetic system for accommodation of near vision, not the sympathetic system.
