2024 APEA PREDICTOR EXAM 2 WITH ACTUAL 60
QUESTION AND ANSWERS RATED A GRADE.
What is the clinically recommended therapeutic approach for managing pityriasis rosea?
CORRECT ANS: Nothing; it is a viral rash and can last up to two months before clearing on its own.
Expert Rationale: Pityriasis rosea is a self-limiting, acute exanthematous skin condition that is believed to
be triggered by a viral infection, most likely a reactivation of human herpesvirus 6 or 7. The condition
follows a predictable course, typically resolving spontaneously within six to twelve weeks without any
specific medical intervention. As such, treatment is generally symptomatic and supportive, focusing on
managing pruritus with antihistamines or topical corticosteroids if necessary. There is no curative
treatment, and the primary role of the clinician is to reassure the patient of its benign and self-resolving
nature while monitoring for any atypical presentations.
What term is used to describe an agent or factor that causes harm or damage to biological tissues?
CORRECT ANS: Deleterious.
Expert Rationale: The term "deleterious" is an adjective used to describe something that has a harmful,
damaging, or injurious effect. In a medical and clinical context, it is frequently applied to agents,
substances, or processes that cause adverse effects on the body's cells, tissues, or organs. For example,
chronic ultraviolet radiation is a deleterious factor for the skin, leading to photoaging and an increased
risk of malignancy. Identifying deleterious factors is a critical component of patient assessment and risk
management, guiding clinical decision-making and preventive health strategies.
What is the standard formula utilized to calculate the ideal body weight for adult males?
CORRECT ANS: Start at 106 pounds and then add 6 for every inch above 5 feet.
Expert Rationale: The Hamwi method is a widely recognized and historically utilized formula for
estimating ideal body weight (IBW) in adults. For males, the formula establishes a baseline weight of 106
pounds for a height of 5 feet. Subsequently, an additional 6 pounds is added for each inch of height
exceeding this baseline. This calculation serves as a valuable clinical tool for estimating weight-related
parameters, including drug dosing, nutritional assessment, and determining pulmonary function test
predicted values. It is important to note that while useful, this formula provides an estimate and does
not account for individual variations in body composition, such as muscle mass and skeletal frame size.
,What is the recommended treatment regimen for managing lichen sclerosus?
CORRECT ANS: Topical steroids, topical calcineuronin inhibitors to suppress the immune system, topical
or oral retinoids, phototherapy.
Expert Rationale: Lichen sclerosus is a chronic, inflammatory dermatological condition of unknown
etiology, characterized by atrophic, white, and wrinkled patches of skin, most commonly affecting the
anogenital region. The primary goal of treatment is to manage symptoms, prevent atrophy, and reduce
the risk of malignant transformation. First-line therapy typically consists of ultrapotent topical
corticosteroids, such as clobetasol propionate, to control inflammation. Topical calcineurin inhibitors
(e.g., tacrolimus, pimecrolimus) are considered steroid-sparing alternatives or adjuncts. In more
refractory cases, topical or oral retinoids may be utilized. Phototherapy, including narrowband UVB or
PUVA, is also a recognized therapeutic option. The treatment strategy is highly individualized and
depends on the severity of the disease, the patient's age, and their response to initial therapies.
What is the characteristic clinical hallmark that serves as a tell-tale sign of malignant hypertension?
CORRECT ANS: Retinopathy and blurred vision; characterized by a diastolic BP of greater than 130.
Expert Rationale: Malignant hypertension is a severe and potentially life-threatening form of
hypertensive emergency characterized by a rapid and significant elevation in blood pressure, classically
defined as a diastolic pressure exceeding 130 mm Hg. It is a medical emergency that can lead to acute
end-organ damage. The hallmark clinical manifestation is hypertensive retinopathy, which is detectable
on fundoscopic examination and may present with findings such as flame-shaped hemorrhages, cotton-
wool spots, and papilledema. Concurrently, patients commonly report symptoms of blurred vision due to
retinal and optic nerve involvement. These signs are critical red flags that necessitate immediate medical
intervention to prevent irreversible damage to the cerebral, cardiac, and renal systems.
What is the fundamental pathophysiological and clinical distinction between a Parkinsonian tremor and
an essential tremor?
CORRECT ANS: A Parkinsonian tremor is also known as a resting tremor and is seen at rest, may look like
pill-rolling. An essential tremor is bilateral, symmetric, and seen when the hands are doing something.
Expert Rationale: Distinguishing between a Parkinsonian tremor and an essential tremor is a critical
component of differential diagnosis in neurology. A Parkinsonian tremor is a resting tremor, meaning it
characteristically presents when the limb is at rest and supported, and it often diminishes with voluntary
movement. It is typically asymmetric and unilateral in its early presentation, manifesting as a slow,
coarse, 4-6 Hz "pill-rolling" movement of the fingers. Conversely, an essential tremor is an action tremor,
most prominent during active movement or sustained posture. It is typically bilateral, symmetric, and
exhibits a higher frequency (8-12 Hz). Essential tremor is the most common movement disorder and its
severity is often exacerbated by stress, fatigue, or anxiety.
, What clinical factors are known to exacerbate an essential tremor, and what factors can provide
symptomatic relief?
CORRECT ANS: Worsened by stress or fatigue, improved by alcohol.
Expert Rationale: The severity of essential tremor is modulated by various physiological and
psychological states. It is well-established that physical and emotional stress, as well as fatigue and
anxiety, can significantly amplify the amplitude of the tremor, making it more noticeable and functionally
limiting. Conversely, the ingestion of small amounts of alcohol (ethanol) is a classic and well-documented
feature of essential tremor, often providing a temporary and substantial improvement in tremor
amplitude. This paradoxical response is a helpful diagnostic clue, although the use of alcohol is not
recommended as a therapeutic strategy due to the risks of dependence and its short-lived effects. The
response to alcohol is thought to be mediated through its effects on the central nervous system.
What is the established first-line pharmacological treatment for the management of trigeminal
neuralgia?
CORRECT ANS: Carbamazepine (Tegretol) or amitriptyline.
Expert Rationale: Trigeminal neuralgia is a neuropathic pain disorder characterized by severe,
paroxysmal, electric shock-like or stabbing pain in the distribution of the trigeminal nerve. The first-line
medical therapy for trigeminal neuralgia is the use of anticonvulsant agents that stabilize neuronal
membranes. Carbamazepine is considered the gold-standard initial treatment, having shown the most
robust evidence for efficacy in reducing the frequency and severity of pain episodes. Oxcarbazepine is
often used as a better-tolerated alternative. Amitriptyline is a tricyclic antidepressant commonly used as
a second-line agent or adjunctive therapy for neuropathic pain. Other options include gabapentin or
pregabalin in cases where first-line agents are ineffective or poorly tolerated.
Are Parkinsonian tremors initially unilateral or bilateral in their presentation?
CORRECT ANS: Unilateral.
Expert Rationale: A cardinal clinical feature of Parkinson's disease is the asymmetric onset of motor
symptoms. The resting tremor, which is one of the hallmark signs, almost always presents unilaterally in
the early stages of the disease. This asymmetry is a key distinguishing factor from other tremor
disorders, such as essential tremor, which is typically bilateral. As the disease progresses over time, the
tremor may eventually become bilateral, though some degree of asymmetry often persists throughout
the disease course.
Where is the temporomandibular joint (TMJ) optimally located and palpated?
CORRECT ANS: Anterior to the tragus.
Expert Rationale: The temporomandibular joint is a complex synovial joint located on each side of the
head that connects the mandible to the temporal bone. For clinical assessment, the TMJ is best palpated
