MCCQE Dumps With Exact Questions and Answers

This patient has been assessed as incapable of making the decision regarding dialysis. MCCQE ELOM objectives emphasize that when a patient lacks decision-making capacity, treatment decisions must be made by a legally authorized substitute decision-maker (SDM) according to provincial/territorial hierarchy. The appropriate next step is to determine whether a formal SDM has been appointed (e.g., power of attorney for personal care) or identify the legally ranked default SDM.

Although the wife may often be the default SDM, this depends on jurisdiction and whether a formal representative has been designated. It is inappropriate to automatically follow the son’s wishes, as he may not be the legal SDM. Nor should the physician impose their own recommendation without engaging the proper decision-making process. A large family meeting may be helpful later but does not replace identifying the legally authorized decision-maker.

Once identified, the SDM must make decisions based on the patient’s prior capable wishes or, if unknown, the patient’s best interests. Properly establishing the SDM ensures ethical and legal compliance in incapacity situations.

Comprehensive and Detailed Explanation:

Patients undergoing splenectomy are at lifelong risk for overwhelming post-splenectomy infection (OPSI), particularly from encapsulated organisms. Vaccination against Streptococcus pneumoniae, Haemophilus influenzae type b, and Neisseria meningitidis is recommended at least 2 weeks prior to elective splenectomy.

Toronto Notes 2023 – Hematology / Surgery:

“Patients undergoing elective splenectomy should receive vaccines against pneumococcus, H. influenzae type b, and meningococcus at least 2 weeks before surgery.”

MCCQE1 Objectives (Hematology > 38-2: Thrombocytopenia and Splenectomy):

“Candidates must ensure vaccination prior to splenectomy to prevent postsplenectomy sepsis.”

Calcium (B) may be considered in chronic steroid users but is not the priority. Azithromycin (C) is not indicated. D is unsafe without tapering. E is only for acute bleeding or extremely low platelets.

This infant has persistent vomiting with feeding-associated distress and poor weight gain, despite appropriate initial nonpharmacologic measures (thickened feeds and hypoallergenic formula). MCCQE pediatrics objectives emphasize distinguishing physiologic reflux (“happy spitter”) from gastroesophageal reflux disease (GERD), which is suggested by feeding aversion/crying and failure to thrive. When conservative strategies fail and GERD is causing significant symptoms or complications (e.g., poor growth, suspected esophagitis contributing to irritability and possibly anemia), escalation to acid suppression is appropriate; a proton pump inhibitor such as omeprazole is used to treat acid-related esophageal injury and improve symptoms in selected infants with suspected erosive disease.

Metoclopramide is not preferred due to limited benefit and risk of extrapyramidal adverse effects. Calcium carbonate antacids are not recommended as ongoing therapy in infants due to safety concerns and inferior efficacy for esophagitis. Bismuth sulfate is not indicated. Loperamide is inappropriate and potentially harmful in infants. Continued monitoring of growth and reassessment for alternative diagnoses or alarm features is essential.
