1. Which of the following is recommended to be tried first for the treatment of mild migraine attacks without significant nausea or vomiting in an adult?
-
Nonsteroidal anti-inflammatory drugs (NSAIDs)
-
Serotonin 1b/1d agonists (triptans)
-
Calcitonin gene-related peptide (CGRP) antagonists
-
Ergotamine (Ergomar) or ergot derivatives
Explanation
Explanation
Correct Answer: (A) Nonsteroidal anti-inflammatory drugs (NSAIDs).
For mild to moderate migraine attacks without significant nausea or vomiting, current guidelines recommend starting with simple analgesics or NSAIDs (such as ibuprofen, naproxen, or aspirin) as first-line therapy. These medications are effective, widely available, and well-tolerated. Triptans are reserved for moderate to severe migraines or those that fail to respond to NSAIDs.
Why Other Options are Incorrect:
B - Triptans: Triptans are highly effective and are the first-line treatment for moderate to severe migraines, but for mild attacks without nausea or vomiting, NSAIDs are the recommended initial treatment due to their comparable efficacy and lower cost.
C - CGRP antagonists: CGRP antagonists (gepants) are newer agents used for acute migraine treatment and prevention, but they are not the recommended first-line therapy for mild migraine attacks. They are typically considered when other options fail or are contraindicated.
D - Ergotamine or ergot derivatives: Ergotamines are older migraine treatments associated with significant side effects including nausea, vasoconstriction, and risk of medication overuse headache. They are not recommended as first-line therapy and have largely been replaced by triptans for moderate to severe attacks.

2. The nurse practitioner is performing an assessment on a female with surgically induced menopause. Which problem is NOT likely related to estrogen deficiency?
-
Iron deficiency anemia
-
Sleep disturbances
-
Vaginal dryness
-
Bone loss
Explanation
Explanation
Correct Answer: (A) Iron deficiency anemia.
Iron deficiency anemia is not a consequence of estrogen deficiency. In fact, women who undergo surgical menopause (oophorectomy) no longer experience menstrual bleeding, which actually reduces iron loss and lowers their risk of iron deficiency anemia compared to premenopausal women. Iron deficiency anemia is more commonly associated with menstruation, poor dietary intake, or gastrointestinal blood loss.
Why Other Options are Incorrect:
B - Sleep disturbances: Estrogen deficiency causes vasomotor symptoms including hot flashes and night sweats, which directly disrupt sleep. Sleep disturbances are a well-established consequence of menopause and estrogen deficiency.
C - Vaginal dryness: Estrogen plays a key role in maintaining vaginal epithelial health and lubrication. Estrogen deficiency leads to genitourinary syndrome of menopause, which includes vaginal dryness, atrophy, and dyspareunia.
D - Bone loss: Estrogen is critical for bone density maintenance by inhibiting osteoclast activity. Its deficiency accelerates bone resorption, leading to osteopenia and osteoporosis. This risk is particularly pronounced in surgically induced menopause, which causes an abrupt drop in estrogen.

3. A 22-year-old patient presents with a mildly erythematous, nontender, rubbery nodule on the right upper eyelid. This is consistent with:
-
conjunctivitis.
-
a hordeolum.
-
blepharitis.
-
a chalazion.
Explanation
Explanation
Correct Answer: (D) a chalazion.
A chalazion is a chronic, granulomatous inflammation of a meibomian gland in the eyelid, presenting as a nontender, firm, rubbery nodule with mild surrounding erythema. Unlike a hordeolum (stye), which is an acute, painful infection, a chalazion is typically painless and develops gradually due to obstruction and lipid accumulation in the gland. It is the classic presentation described in this question.
Why Other Options are Incorrect:
A. Conjunctivitis — Conjunctivitis involves inflammation of the conjunctiva, presenting with redness, discharge, and irritation of the eye itself, not a discrete nodule on the eyelid.
B. A hordeolum — A hordeolum (stye) is an acute, painful, tender abscess of an eyelid gland caused by bacterial infection, typically Staphylococcus aureus. The nontender, rubbery nature of this nodule rules out a hordeolum.
C. Blepharitis — Blepharitis is a chronic inflammation of the eyelid margins presenting with crusting, scaling, and irritation along the lid edge, not a discrete nodular mass.

4. A 33-year-old female patient presents with complaints of diplopia. On assessment, she exhibits strabismus when she looks to the left. These findings are consistent with palsy of:
-
cranial nerve III.
-
cranial nerve IV.
-
cranial nerve V.
-
cranial nerve VI.
Explanation
Explanation
Correct Answer: (D) Cranial nerve VI.
Cranial nerve VI (the abducens nerve) controls the lateral rectus muscle, which is responsible for abducting the eye (moving it outward/to the side). A palsy of CN VI results in the inability to abduct the affected eye, causing the eye to deviate medially. When the patient attempts to look to the left, the left eye cannot move laterally, resulting in strabismus and diplopia. This is a classic presentation of CN VI palsy.
Why Other Options are Incorrect:
A - Cranial nerve III: CN III (oculomotor) palsy typically presents with ptosis, a "down and out" eye position, and a dilated pupil. It does not specifically cause the inability to look laterally.
B - Cranial nerve IV: CN IV (trochlear) controls the superior oblique muscle and its palsy causes vertical diplopia, particularly when looking downward and inward (e.g., difficulty going down stairs), not lateral gaze deficits.
C - Cranial nerve V: CN V (trigeminal) is a sensory and motor nerve for the face and jaw. It has no role in eye movement and would not cause diplopia or strabismus.

5. A 47-year-old male with gastroesophageal reflux disease (GERD) is experiencing symptoms of esophagitis. The NP prescribed a proton pump inhibitor (PPI) instead of an H2 receptor antagonist because the PPI:
-
has a more immediate onset of action.
-
is better at controlling nocturnal acid breakthrough.
-
has fewer drug-drug interactions.
-
has better efficacy in the healing of esophagitis.
Explanation
Explanation:
Correct Answer: (D) Has better efficacy in the healing of esophagitis.
PPIs are the preferred treatment for esophagitis associated with GERD because they provide superior acid suppression compared to H2 receptor antagonists. PPIs irreversibly inhibit the proton pump, leading to more complete and sustained suppression of gastric acid, which promotes healing of esophageal mucosa more effectively.
Why Other Options are Incorrect:
A - Has a more immediate onset of action: H2 receptor antagonists actually have a faster onset of action compared to PPIs. PPIs require activation in an acidic environment and take longer to reach full effect.
B - Is better at controlling nocturnal acid breakthrough: H2 receptor antagonists are actually sometimes added at bedtime specifically to address nocturnal acid breakthrough, which can still occur with PPI use.
C - Has fewer drug-drug interactions: PPIs are metabolized through the CYP450 system and can have significant drug interactions (e.g., with clopidogrel), so this is not an advantage of PPIs over H2 blockers.

6. Which of the following is a secondary cause of hyperlipidemia?
-
Hypothyroidism
-
Recent dietary excess and weight gain
-
Lack of exercise
-
Osteoporosis
Explanation
Explanation
Correct Answer: (A) Hypothyroidism.
Secondary hyperlipidemia refers to elevated lipid levels caused by an underlying medical condition or medication rather than primary (genetic) dyslipidemia or lifestyle factors. Hypothyroidism is a well-established secondary cause of hyperlipidemia, as thyroid hormone plays a critical role in regulating LDL receptor expression and lipid metabolism. Reduced thyroid hormone levels lead to decreased LDL clearance and elevated total cholesterol and triglycerides.
Why Other Options are Incorrect:
B - Recent dietary excess and weight gain: While a high-fat diet and obesity contribute to elevated lipid levels, these are lifestyle-related risk factors for primary or mixed hyperlipidemia, not secondary causes arising from an underlying disease process.
C - Lack of exercise: Physical inactivity can worsen lipid profiles, particularly by lowering HDL levels, but it is a lifestyle factor rather than a disease-based secondary cause of hyperlipidemia.
D - Osteoporosis: Osteoporosis is a condition of reduced bone density and is not associated with causing hyperlipidemia. It is unrelated to lipid metabolism.

7. Which of the following symptoms is typical of hypothyroidism?
-
Cold intolerance
-
Diarrhea
-
Increased perspiration
-
Weight loss
Explanation
Explanation
Correct Answer: (A) Cold intolerance
Hypothyroidism results from insufficient thyroid hormone production, leading to a generalized slowing of metabolic processes. Cold intolerance is a classic symptom because reduced thyroid hormone impairs thermogenesis and the body's ability to maintain normal temperature. Other hallmark symptoms include fatigue, weight gain, constipation, dry skin, bradycardia, and depression.
Why Other Options are Incorrect:
B. Diarrhea — Diarrhea is associated with hyperthyroidism, where accelerated gut motility results from excess thyroid hormone. Hypothyroidism characteristically causes constipation due to slowed gastrointestinal motility.
C. Increased perspiration — Increased perspiration (diaphoresis) is a symptom of hyperthyroidism due to increased metabolic rate and heat production. Hypothyroid patients typically present with dry skin and reduced sweating.
D. Weight loss — Weight loss is characteristic of hyperthyroidism due to an elevated metabolic rate. Hypothyroidism causes weight gain due to reduced metabolism and fluid retention.

8. The guardian of a healthy 3½-year-old male reports continuous unsuccessful attempts at toilet training over the past 6 months. The guardian states that the child is incontinent of urine at least once daily and a few nights a week. He wears "pull-up" diapers and successfully uses a toddler toilet chair for bowel movements only. Urine dipstick is negative for blood and leukocytes. The most appropriate intervention is to:
-
provide the most current and proven recommendations for toilet training.
-
prescribe desmopressin (DDAVP) nightly.
-
encourage continued toilet training. This is normal for a child his age, and he may need a little more time.
-
encourage the mother to seek a psychological evaluation for her child.
Explanation
Explanation:
Correct Answer: (C) Encourage continued toilet training. This is normal for a child his age, and he may need a little more time.
Bladder control and toilet training readiness varies among children. At 3½ years, it is developmentally normal for some children to still be working on urinary continence, especially at night. Since the urine dipstick is negative and the child is already using the toilet for bowel movements, there is no pathological concern. Reassurance and encouragement are the most appropriate interventions at this stage.
Why Other Options are Incorrect:
A - Provide the most current and proven recommendations for toilet training: While education is helpful, the clinical picture here points to normal developmental variation, making simple reassurance and encouragement more appropriate than formal training recommendations.
B - Prescribe desmopressin (DDAVP) nightly: DDAVP is indicated for primary nocturnal enuresis in children typically older than 6 years; it is not appropriate for a 3½-year-old who is still in the normal range of toilet training development.
D - Encourage the mother to seek a psychological evaluation: There is no indication of a psychological issue here. The child's presentation is within normal developmental limits and does not warrant psychological referral.

9. The finding that would be most concerning for testicular cancer in a 22-year-old male is:
-
painless unilateral testicular swelling.
-
an inflamed scrotum.
-
bilateral testicular pain.
-
bilateral diffuse scrotal edema.
Explanation
Explanation
Correct Answer: (A) Painless unilateral testicular swelling.
The classic presentation of testicular cancer is a painless, firm, unilateral testicular mass or swelling. The absence of pain is a key distinguishing feature, as many patients delay seeking care because they assume pain is necessary for a serious condition. Testicular cancer is the most common malignancy in males aged 15–35, making this finding in a 22-year-old highly concerning and requiring urgent evaluation with scrotal ultrasound.
Why Other Options are Incorrect:
B - An inflamed scrotum: Scrotal inflammation is more consistent with epididymitis, orchitis, or scrotal cellulitis — all of which are infectious or inflammatory conditions rather than malignancy.
C - Bilateral testicular pain: Pain in both testes is more consistent with an infectious, inflammatory, or referred pain etiology. Testicular cancer typically presents unilaterally and without significant pain.
D - Bilateral diffuse scrotal edema: Bilateral scrotal edema suggests a systemic cause such as heart failure, hypoalbuminemia, or venous insufficiency rather than a localized testicular malignancy.

10. An adult patient assigned female at birth reports urinary leakage, frequency, and nocturia. Obtaining a postvoid residual urine volume and a voiding diary are the most beneficial in identifying:
-
urinary tract infections.
-
urge incontinence.
-
overflow incontinence.
-
stress incontinence.
Explanation
Explanation
Correct Answer: (C) Overflow incontinence.
A postvoid residual (PVR) urine volume measurement is specifically useful in identifying overflow incontinence, which occurs when the bladder cannot empty completely, leading to overdistension and leakage. An elevated PVR (typically >200 mL) indicates incomplete bladder emptying, consistent with overflow incontinence. A voiding diary helps document patterns of frequency, nocturia, and leakage, which together support this diagnosis.
Why Other Options are Incorrect:
A - Urinary tract infections: UTIs are diagnosed through urinalysis and urine culture, not primarily through PVR measurement or a voiding diary.
B - Urge incontinence: Urge incontinence is characterized by a sudden, strong urge to void followed by involuntary leakage. While a voiding diary can support its diagnosis, a PVR is not the key diagnostic tool for urge incontinence, as bladder emptying is typically complete.
D - Stress incontinence: Stress incontinence involves leakage with increased intra-abdominal pressure (e.g., coughing, sneezing) and is typically diagnosed clinically through history and provocative testing, not PVR measurement.
