ACE inhibitors such as ramipril are first-line for CHF with reduced ejection fraction, but a common adverse effect is a dry cough due to bradykinin accumulation. Angiotensin II receptor blockers (ARBs) offer the same hemodynamic and survival benefits without causing cough.
Toronto Notes 2023 - Cardiology, "Heart Failure" Section:
"In patients intolerant to ACE inhibitors due to cough, an ARB (e.g., losartan, valsartan) is the recommended substitute. ARBs also reduce mortality and hospitalizations in heart failure with reduced ejection fraction." MCCQE1 Objectives (Internal Medicine > 76-3: Congestive Heart Failure):
"Candidates should recognize ARBs as an alternative to ACE inhibitors in patients who develop adverse effects such as cough, while maintaining the mortality benefit." Other options (B-E) do not offer mortality benefits in CHF and may worsen the condition (e.g., CCBs, alpha- blockers, NSAIDs like COX-2 inhibitors).

In most Canadian provinces and territories, physicians are legally obligated to report patients who pose a danger due to medical conditions affecting driving ability. Given the history of TIAs and continued unsafe driving, reporting is necessary for public safety.
Toronto Notes 2023 - ELOM, "Fitness to Drive" Section:
"Physicians must report to motor vehicle authorities if a patient poses a risk to public safety due to a medical condition. TIAs are considered reportable if they impair ability and the patient does not comply with driving restrictions." MCCQE1 Objectives (ELOM > 99-1: Medical Fitness and Reporting):
"Candidates must recognize situations requiring mandatory reporting of patients unfit to drive due to neurologic or other impairing conditions." You may still discuss with the patient (B), but this does not replace the duty to report. Physically taking the license (C) is illegal. Refusing care (D) is unethical. A neurologist (E) could be helpful but would delay action in a clear case.

Nonprescription opioid use during opioid agonist therapy is not uncommon. The response shouldbe supportive and not punitive. Increasing the frequency of follow-up enhances monitoring, supports adherence, and prevents relapse.
Toronto Notes 2023 - Psychiatry, "Substance Use Disorders":
"Patients who relapse during opioid agonist treatment benefit from closer monitoring and increased support, including more frequent follow-up and psychosocial interventions." MCCQE1 Objectives (Psychiatry > 71-5: Substance Use and Addiction):
"Candidates must manage relapses in opioid use by optimizing follow-up and support, not by discontinuing or reducing therapy prematurely." Tapering or discontinuing therapy (A, E) risks destabilizing treatment. Removing take-home doses (B) may be warranted later but not first. Cannabinoids (D) are not first-line adjuncts.

Children with a first-degree relative who has premature coronary artery disease or hypercholesterolemia should undergo fasting lipid screening between ages 2-10. Since the child is 10, screening is indicated.
Toronto Notes 2023 - Pediatrics, "Preventive Care in Children":
"Lipid screening is recommended for children #2 years old with a family history of early cardiovascular disease or hypercholesterolemia." MCCQE1 Objectives (Pediatrics > 78-1: Preventive Medicine):
"Candidates must screen children at high risk of cardiovascular disease appropriately, including lipid profile for familial hyperlipidemia." Diet and exercise counseling may follow screening, but testing is the first step. Reassurance alone (C) is inappropriate. Homocysteine (E) and HbA1c are not first-line tests in this setting.

Comprehensive and Detailed Explanation:
This patient is pregnant and febrile with a new headache, photophobia, and clonus - all features concerning for preeclampsia with neurologic involvement. Clonus is a key finding suggestive of central nervous system irritability. Urine protein/creatinine ratio helps confirm the diagnosis of preeclampsia.
Toronto Notes 2023 - Obstetrics, Hypertensive Disorders in Pregnancy:
"Headache, clonus, and visual disturbances are concerning for severe preeclampsia. A urine protein/creatinine ratio or 24-hour urine collection confirms diagnosis." MCCQE1 Objectives - Obstetrics > Hypertension in Pregnancy:
"Candidates must recognize signs of preeclampsia and assess with appropriate biochemical testing." CT (A) or LP (B) are not indicated unless focal neurologic signs or seizures are present. Fetal imaging and amniocentesis (C, D) do not address maternal symptoms.
