Work through these case-based single-best-answer questions. Open the answer only after committing to a choice, then review the clinical reasoning and safety priority.
These educational samples emphasize diagnosis, investigations, emergencies, pharmacology, interactions, and referral. They are not official CONO questions.
Question 1
Clinical case: A 62-year-old patient presents with crushing substernal chest pressure, diaphoresis, and nausea for 30 minutes.
What is the most appropriate immediate action?
Show correct answer and explanation
Correct answer: C
This presentation is concerning for acute coronary syndrome. Emergency activation and immediate medical assessment take priority over outpatient or naturopathic management.
Question 2
Clinical case: A patient taking warfarin asks about adding a concentrated herbal product that may increase bleeding risk.
What is the best next step?
Show correct answer and explanation
Correct answer: C
Medication reconciliation and interaction assessment are essential. Changes to anticoagulation should be coordinated with the prescribing clinician and monitored appropriately.
Question 3
Clinical case: A 24-year-old has polyuria, polydipsia, abdominal pain, vomiting, deep rapid respirations, and confusion.
Which diagnosis is most concerning?
Show correct answer and explanation
Correct answer: B
The combination of osmotic symptoms, GI symptoms, Kussmaul-type respirations, and altered mental status is highly concerning for diabetic ketoacidosis and requires emergency care.
Question 4
Clinical case: A patient has fatigue, pallor, microcytosis, low ferritin, and elevated total iron-binding capacity.
Which diagnosis best fits this pattern?
Show correct answer and explanation
Correct answer: A
Low ferritin with microcytosis and increased iron-binding capacity is the classic laboratory pattern of iron-deficiency anemia. The underlying cause should also be investigated.
Question 5
Clinical case: A patient develops sudden unilateral weakness, facial droop, and difficulty speaking 20 minutes ago.
What is the most appropriate response?
Show correct answer and explanation
Correct answer: C
Acute focal neurological deficits suggest stroke. Time-sensitive emergency assessment and reperfusion eligibility evaluation are critical.
Question 6
Clinical case: A patient with asthma is using a short-acting bronchodilator several times every day and waking at night with symptoms.
What does this pattern most strongly indicate?
Show correct answer and explanation
Correct answer: B
Frequent rescue use and nocturnal symptoms indicate inadequate asthma control. The patient needs prompt reassessment of severity, adherence, technique, triggers, and controller therapy.
Question 7
Clinical case: A pregnant patient at 34 weeks has severe headache, visual changes, right upper quadrant pain, and markedly elevated blood pressure.
What is the priority?
Show correct answer and explanation
Correct answer: C
Severe hypertension with neurological and hepatic symptoms in pregnancy is an obstetric emergency requiring urgent hospital assessment.
Question 8
Clinical case: A patient presents with a hot, swollen, exquisitely painful single joint and fever.
Which condition must be urgently excluded?
Show correct answer and explanation
Correct answer: A
Septic arthritis can rapidly destroy a joint and cause systemic illness. Urgent aspiration, culture, and medical treatment are required.
Question 9
Clinical case: A patient taking an ACE inhibitor reports new facial and tongue swelling with difficulty breathing.
What is the most appropriate action?
Show correct answer and explanation
Correct answer: C
ACE inhibitor-associated angioedema can threaten the airway. Emergency airway assessment is required.
Question 10
Clinical case: A patient has recurrent episodes of palpitations, sweating, severe headache, and markedly elevated blood pressure.
Which diagnosis should be considered?
Show correct answer and explanation
Correct answer: A
The episodic triad of headache, diaphoresis, and palpitations with hypertension is classic for catecholamine excess and warrants appropriate medical evaluation.
