5. Neurological Assessment and Complex Disorder Management
1. A patient with a history of Graves' disease presents with increased heart rate, tremors, and
exophthalmos. Which finding would be most consistent with the expected TSH and free T4
levels in this patient?
A. Elevated TSH, elevated free T4
B. Suppressed TSH, elevated free T4
C. Suppressed TSH, low free T4
D. Normal TSH, elevated free T4
CORRECT ANSWER : B
Rationale: Graves' disease is a form of primary hyperthyroidism caused by thyroid-stimulating
immunoglobulins that mimic TSH, leading to autonomous production of thyroid hormones. The
high circulating T4 levels exert negative feedback on the anterior pituitary, resulting in
suppressed TSH production.
2. A 55-year-old patient is diagnosed with Syndrome of Inappropriate Antidiuretic Hormone
(SIADH). Which laboratory finding would a nurse practitioner anticipate?
, A. Hypernatremia and high serum osmolality
B. Hyponatremia and low serum osmolality
C. Hyperkalemia and metabolic acidosis
D. Elevated serum ADH and diluted urine
CORRECT ANSWER : B
Rationale: SIADH involves excessive, unregulated release of ADH, leading to free water
retention and dilutional hyponatremia. This results in decreased serum osmolality and typically
concentrated, rather than diluted, urine.
3. A patient with metastatic lung cancer presents with a serum calcium level of 14 mg/dL. Which
mechanism most likely explains this finding?
A. Increased dietary calcium intake
B. Parathyroid hormone-related protein (PTHrP) secretion
C. Decreased renal clearance of calcium
D. Primary hyperparathyroidism
CORRECT ANSWER : B
Rationale: Many malignancies, particularly squamous cell carcinomas of the lung, secrete
PTHrP, which binds to PTH receptors and stimulates bone resorption and renal calcium
reabsorption. This is distinct from primary hyperparathyroidism and is a common cause of
hypercalcemia of malignancy.
4. A patient is prescribed a fentanyl patch for chronic cancer pain. Which education point is critical
to prevent fatal toxicity?
A. Apply heat to the patch site to improve absorption
B. Avoid external heat sources over the patch application site
C. Change the patch every 12 hours
D. Cut the patch in half to adjust the dose
CORRECT ANSWER : B
, Rationale: Fentanyl patches rely on a steady-state absorption rate through the skin; external
heat sources (heating pads, hot baths) significantly increase drug absorption, leading to
potentially fatal respiratory depression. Patches should never be cut, and the typical dosing
interval is 72 hours.
5. A patient with Parkinson’s disease reports increased "off" time between doses of
carbidopa/levodopa. What is the most appropriate medication adjustment strategy?
A. Increase the dose of carbidopa only
B. Add a COMT inhibitor or MAO-B inhibitor
C. Discontinue levodopa immediately
D. Administer the medication with a high-protein meal
CORRECT ANSWER : B
Rationale: COMT inhibitors and MAO-B inhibitors decrease the metabolic breakdown of
levodopa, effectively extending its duration of action and reducing "off" time. Protein competes
with levodopa for transport across the blood-brain barrier, so meals should be separated from
dosing.
6. A patient presents with signs of Cushing's syndrome. An elevated 24-hour urinary free cortisol
level is confirmed. Which diagnostic test would best differentiate between an adrenal source and
a pituitary source?
A. Serum TSH level
B. Low-dose and high-dose dexamethasone suppression tests
C. Fasting blood glucose
D. MRI of the kidneys
CORRECT ANSWER : B
Rationale: Dexamethasone suppression tests help determine the feedback sensitivity of the
hypothalamic-pituitary-adrenal axis. Pituitary tumors (Cushing's disease) often show
suppression with high-dose dexamethasone, whereas adrenal tumors do not suppress at any
dose.
7. Which pharmacological agent is considered the first-line treatment for neuropathic pain
associated with diabetic peripheral neuropathy?
A. Ibuprofen
, B. Gabapentin or Pregabalin
C. Morphine sulfate
D. Acetaminophen
CORRECT ANSWER : B
Rationale: Neuropathic pain arises from nerve damage and often responds poorly to NSAIDs or
opioids; calcium channel alpha-2-delta ligands like gabapentin and pregabalin modulate
excitatory neurotransmitter release and are established first-line therapies.
8. A 30-year-old female presents with irregular menses, hirsutism, and acne. Ultrasound reveals
multiple ovarian cysts. Which underlying pathophysiology is the most likely driver?
A. Primary ovarian failure
B. Hyperandrogenism and insulin resistance
C. Elevated estrogen levels
D. Decreased LH/FSH ratio
CORRECT ANSWER : B
Rationale: Polycystic Ovary Syndrome (PCOS) is frequently characterized by hyperandrogenism
and insulin resistance, which interfere with normal follicle development and ovulation.
Treatment focuses on managing insulin sensitivity and the hormonal imbalance.
9. A patient is receiving chemotherapy and develops febrile neutropenia. What is the primary
priority in clinical management?
A. Increase the chemotherapy dose to kill residual cells
B. Immediate administration of broad-spectrum antibiotics
C. Administer corticosteroids to reduce inflammation
D. Discontinue all medications for 48 hours
CORRECT ANSWER : B
Rationale: Febrile neutropenia is a life-threatening oncological emergency because the patient
lacks the immune cells to fight off even minor infections. Prompt, broad-spectrum antibiotic
coverage is critical before cultures are even finalized.
