An 80 year old woman has a painful right wrist and is seen in the Emergency Department. X-ray: Fracture of right distal radius. Which is the most appropriate treatment?

Correct Answer: A

Rationale: The most appropriate treatment for an 80-year-old woman with a painful right wrist and a distal radius fracture is option A) Below elbow backslab plaster of Paris. The rationale for this choice is based on the principles of managing distal radius fractures in elderly patients. Conservative management with a below elbow backslab plaster of Paris is preferred in this age group due to the potential risk of complications associated with surgical interventions, such as open reduction and internal fixation. Option B) Below elbow full plaster of Paris is not the best choice as it may restrict wrist movement unnecessarily, leading to stiffness and discomfort. Option C) Closed reduction of fracture may not provide adequate stability for proper healing in this elderly patient population. Option D) Open reduction and internal fixation is a more invasive approach that carries higher risks of complications in older adults. In an educational context, it is important for healthcare professionals to consider the age and specific needs of patients when determining the most appropriate treatment for distal radius fractures. Conservative management with a backslab plaster of Paris is often the preferred initial approach in elderly patients to minimize risks and promote optimal healing outcomes.

Correct Answer: B

Rationale: The correct initial treatment for a 28-year-old woman with intermittent headaches, dull ache, and neck tightness is option B) Paracetamol. Paracetamol is a first-line treatment for tension-type headaches, which present with dull, non-throbbing pain often associated with neck tightness. It is safe, effective, and well-tolerated for mild to moderate headaches. Option A) Aspirin is not the best choice because it may aggravate the headaches or cause medication-overuse headaches if used frequently. Option C) Prednisolone is a corticosteroid used for inflammatory conditions, not for primary headaches. Option D) Sumatriptan is a triptan medication used for migraines, not for tension-type headaches. In an educational context, understanding the appropriate treatment for different types of headaches is crucial for healthcare providers to provide effective care. This question emphasizes the importance of differentiating between headache types and selecting the most suitable treatment based on the patient's symptoms and history. It also highlights the significance of choosing safe and evidence-based treatments to manage psychiatric emergencies effectively.

Correct Answer: C

Rationale: In this scenario, the most appropriate treatment for the 45-year-old woman with flu-like symptoms, palpitations, and abnormal thyroid function tests indicating hyperthyroidism is option C) Propranolol. Propranolol is a non-selective beta-adrenergic blocker that helps alleviate symptoms of hyperthyroidism such as palpitations, tremors, and anxiety by blocking the effects of excessive thyroid hormones on the heart and other tissues. Option A) Carbimazole is used to treat hyperthyroidism by inhibiting thyroid hormone synthesis and is not indicated for immediate symptom relief. Option B) Prednisolone is a corticosteroid that does not address the underlying cause of hyperthyroidism and is not the first-line treatment for this condition. Option D) Radioiodine is a definitive treatment for hyperthyroidism but is not the initial choice for managing acute symptoms. Educationally, understanding the appropriate treatment for psychiatric emergencies like hyperthyroidism is crucial for healthcare providers, particularly in emergency settings. Propranolol can provide rapid relief of symptoms while further diagnostic workup and definitive treatment planning can be initiated. Emphasizing the rationale behind each treatment option helps learners grasp the importance of targeted therapy based on underlying pathophysiology.

Correct Answer: C

Rationale: In this scenario, the most appropriate diagnostic investigation for a 5-day-old boy with poor urinary stream and bilateral hydronephrosis on antenatal ultrasound is a MCUG (Voiding Cystourethrogram). The MCUG is the best choice because it is a dynamic study that can evaluate vesicoureteral reflux, urethral abnormalities, and bladder emptying. It provides valuable information on the anatomy and function of the urinary tract in infants. CT scan of the renal tract (Option A) involves radiation exposure and is not typically indicated as a first-line study in infants due to concerns about radiation exposure. DMSA (Option B) is usually used to assess for renal scarring, not for evaluating hydronephrosis. Repeat ultrasound (Option D) may not provide the functional information needed to guide management in this case. Educationally, understanding the appropriate diagnostic investigations in pediatric patients with urinary issues is crucial for healthcare professionals working in pediatric emergency settings. It is essential to consider the risks and benefits of each diagnostic test, especially in infants, to provide optimal care while minimizing unnecessary radiation exposure.

Correct Answer: D

Rationale: In the case of a 58-year-old woman with worsening urinary frequency and urgency, the most appropriate initial management is option D) Supervised bladder training. This choice is correct because supervised bladder training involves behavioral techniques aimed at improving bladder control by gradually increasing the time between bathroom visits. It helps the patient regain control over their bladder function and can be effective in managing urinary symptoms like frequency and urgency. Option A) Intermittent self-catheterization is not the most appropriate initial management in this case because it is typically used in conditions where the patient is unable to empty their bladder completely, not for urinary frequency and urgency. Option B) Nitrofurantoin is an antibiotic commonly used to treat urinary tract infections, which may not address the underlying issue of urinary frequency and urgency in this patient. Option C) Oxybutynin is a medication used to treat overactive bladder by relaxing the bladder muscles. While it can be beneficial for some patients with urinary urgency and frequency, supervised bladder training is often preferred as a first-line non-pharmacological approach before resorting to medications. In an educational context, it is important to understand the principles behind different management options for urinary symptoms to provide optimal care for patients. Behavioral interventions like supervised bladder training can empower patients to actively participate in managing their symptoms and improve their quality of life without necessarily resorting to medications or invasive procedures. Understanding the rationale behind each option helps healthcare providers make informed decisions tailored to individual patient needs.
