Correct Answer: D

Rationale: The Romberg test assesses the maintenance of standing balance by having the patient stand with feet together, arms at the sides, and eyes closed. If the patient sways or loses balance, it may indicate proprioceptive deficits. Conductive hearing loss (A) is related to sound transmission issues in the outer or middle ear, not balance. Lateralization of hearing (B) relates to distinguishing sound direction. Sensorineural loss (C) involves inner ear or auditory nerve damage, not balance. Therefore, the correct answer is D as the Romberg test specifically evaluates standing balance.

Correct Answer: D

Rationale: The correct answer is D because cranial nerve X, also known as the vagus nerve, controls the movement of the soft palate and uvula. Asking the patient to say "ahhh" assesses the function of CN X as the soft palate and uvula should elevate symmetrically. A: Observing the patient's ability to articulate specific words does not specifically test CN X function. B: Assessing movement of the hard palate and uvula with the gag reflex primarily tests CN IX (glossopharyngeal nerve). C: Having the patient stick out the tongue and observing for tremors or pulling to one side primarily tests CN XII (hypoglossal nerve).

Correct Answer: A

Rationale: The correct answer is A: An optic disc that is a yellow-orange colour. This is a normal finding because the optic disc typically appears yellow-orange due to the presence of nerve fibers. The yellow-orange color is due to the absence of blood vessels in this area. This is a normal anatomical characteristic of the optic disc. Option B is incorrect because blurred optic disc margins can indicate pathology such as papilledema. Option C is incorrect because the presence of pigmented crescents in the macular area can indicate a condition like myopic degeneration, not a normal finding. Option D is incorrect because the macula is normally located temporally, not nasally, to the optic disc.

Correct Answer: C

Rationale: The correct answer is C because it demonstrates cultural sensitivity and respect for the patient's comfort. Placing the nurse's thumbs on either side of the trachea and tilting the patient's head forward is a non-threatening and non-invasive approach to examining the thyroid. This position allows the nurse to assess the thyroid gland without causing discomfort or intimidation to the patient. Choice A is incorrect because having the nurse's hands placed firmly around the neck from behind may be perceived as invasive and threatening to the patient. Choice B is incorrect because having the nurse's thumbs on the patient's neck with eyes averted toward the ceiling may come across as awkward and unprofessional. Choice D is incorrect because tilting the patient's head backward can cause discomfort and may not be culturally sensitive as it can be perceived as invasive.

Correct Answer: D

Rationale: The correct answer is D: Elongated head with heavy eyebrow ridge. Paget's disease is a bone disorder characterized by abnormal bone remodeling, leading to enlarged and deformed bones. The elongated head and heavy eyebrow ridge are typical features seen in individuals with Paget's disease due to overgrowth of bones in the skull. A: Positive MacEwen's sign - This finding is associated with congenital hip dysplasia, not Paget's disease. B: Premature closure of the sagittal suture - This is a characteristic finding in craniosynostosis, not Paget's disease. C: Headache, vertigo, tinnitus, and deafness - These symptoms are more indicative of an inner ear disorder or vestibular dysfunction, not Paget's disease.
