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: D

Rationale: The correct answer is D because a normal pupillary light reflex involves the constriction of both pupils in response to bright light. This reflex is controlled by the autonomic nervous system, specifically the parasympathetic nervous system. When light is detected by the retina, signals are sent to the brain which then triggers the constriction of both pupils to reduce the amount of light entering the eye. Choices A, B, and C are incorrect because they do not accurately describe the pupillary light reflex. Vision convergence, light reflection, and focusing the image at the center of the pupil are not directly related to the pupillary light reflex.

Correct Answer: C

Rationale: The correct answer is C: Bell's palsy. Bell's palsy is characterized by sudden weakness or paralysis of the facial muscles, resulting in drooping of the face, inability to raise the eyebrow or close the eye, and difficulty with facial expressions and functions like whistling. In this case, the patient's symptoms of left-sided facial paralysis point towards Bell's palsy as the likely diagnosis. Cushing's syndrome (A) is a hormonal disorder, Parkinson's syndrome (B) is a neurodegenerative disorder affecting movement, and a cerebrovascular accident (D) typically presents with more generalized neurological deficits rather than isolated facial paralysis.

Correct Answer: C

Rationale: The correct answer is C: tinnitus. Tinnitus is the perception of sound without an external source, often described as ringing, buzzing, or hissing. In this case, the patient reporting a buzzing sound aligns with tinnitus. Vertigo (A) is a sensation of spinning or dizziness, not a sound perception. Pruritus (B) is itching, not a sound perception. Cholesteatoma (D) is a benign growth in the middle ear, not specifically related to sound perception. Therefore, tinnitus is the most appropriate choice based on the patient's symptom of hearing a buzzing sound.
