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.

Correct Answer: D

Rationale: The correct answer is D: increased intracranial pressure. Papilledema is swelling of the optic disc due to increased pressure in the brain. It is a sign of serious conditions like brain tumors, head trauma, or hydrocephalus. The other choices are incorrect because retinal detachment presents with visual disturbances and floaters (A), diabetic retinopathy with retinal damage due to diabetes (B), and acute-angle glaucoma with sudden eye pain and blurred vision (C). Papilledema specifically indicates increased intracranial pressure, making choice D the correct answer.

Correct Answer: C

Rationale: The correct answer is C because the nurse should use the Snellen chart positioned 6.1 m (20 ft) away to assess visual acuity. This is the standard method for testing distance vision. The nurse should ask the patient to read the letters on the chart from the top row down, covering one eye at a time if necessary. This method provides an accurate measurement of visual acuity at a distance. A: Performing the confrontation test assesses visual fields, not visual acuity. B: Using a Jaeger card is for near vision testing, not distance visual acuity. D: Assessing the ability to read newsprint at a close distance does not provide an accurate measurement of visual acuity at a distance.

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).
