Incorrect- It is not an essential part of physical examination for a newly diagnosed patient with hypertension. +
The cellular organelle involved in I-cell disease disease is the Golgi apparatus, which normally modifies N-oligosaccharides on asparagine and adds O-oligosaccharides to serine and threonine residues. +
Incorrect- Idiopathic thrombocytopenic purpura is a bleeding disorder in which the immune system destroys platelets, which are necessary for normal blood clotting. Persons with the disease have too few platelets in the blood. But findings of gastroenteritis and acute renal failure are more suggestive of HUS. +
Incorrect- This newborn is showing signs of Down syndrome. Café au lait spots are associated with neurofibromatosis. +
Incorrect- If aortic stenosis is found on echocardiogram and the patient is symptomatic, the next test would be cardiac catheterization. This would allow for direct measurement of the pressure gradient across the valve. It would also allow for evaluation of the status of the coronary arteries in order to determine whether CABG would need to be performed along with valve replacement. +
Pasteurella multocida is sensitive to amoxicillin-clavulanate, which can be used in the prophylaxis and treatment of pasteurellosis. The disease may also be treated with fluoroquinolones or tetracyclines. +
Empiric treatment of hematogenous osteomyelitis in patients with hemoglobinopathies includes coverage for Salmonella, ''E. coli'', and ''S. aureus'' species. Regimens should include ciprofloxacin and either oxacillin/nafcillin/ceftriaxone or vancomycin/linezolid depending on risk of MRSA. +
Agents that lack anaerobic coverage as well as coverage against ''Eikenella corrodens'', ''Haemophilus'' species, and ''Staphylococcus aureus'' are not appropriate for prophylaxis. Cefazolin does not cover anaerobic organisms or ''Eikenella'' species. +
Huntington disease has an autosomal dominant mode of inheritance similar to familial hypertrophic cardiomyopathy (HCM). +
N-Acetylcysteine replenishes the reduced form of glutathione, which neutralizes the oxidative stress associated with acetaminophen overdose. It is also used in reducing the mucus viscosity in patients with cystic fibrosis by isolating disulfide bonds. +
Coarctation of the aorta, which is commonly associated with Turner syndrome, results from ectopic ductal tissue or from abnormal development of the fourth and sixth aortic arch. +
<font color="Green">'''Correct.'''</font>Calcium supplementation (calcium gluconate 10% (10ml), preferably through a central venous catheter as the calcium may cause phlebitis) does not lower potassium but decreases myocardial excitability, protecting against life threatening arrhythmias. +
<font color="red">'''Incorrect.'''</font> Oral NSAIDs may slightly control the pain associated with a plain rib fracture, but it is not enough to prevent the hypoventilation which could lead to pneumonia, specially in the elderly. +
<font color="red">'''Incorrect.'''</font>This is an important step to rule out arrhythmias in case of a myocardial contusion. +
