The patient is on Iv pressors already and switching to another pressor will be of little benefit. The mainstay of treatment is stop the blood loss as early as possible. +
Hemodilution and increased GFR associated with pregnancy leads to low values of BUN and Creatinine. +
'''Incorrect'''-Estrogen use through any route increases the risk of thromboembolitic events like deep vein thrombosis and stroke. +
A chest X-ray is not necessary because the patient has no cardiac or pulmonary pathology. +
Cryptococcus neoformans causes meningitis in AIDS patients predominantly those with a CD4 below 100 cells/mm<sup>3</sup>. +
Pick bodies are aggregates of tau proteins that are characteristic of Pick's disease. Patients with Pick's disease present with frontotemporal atrophy that causes dementia, parkinsonism, change in personality, and aphasia. Elevation of 14-3-3 protein in CSF is not typical in Pick's disease. +
'''Incorrect''' : Patients with the constellation of reactive arthritis, tenosynovitis, and urethritis (formerly Reiter syndrome), unlike those with typical DGI, also have one or more of the following: conjunctivitis; circinate balanitis; or keratoderma blenorrhagicum +
'''Correct'''-Diabetics have a high risk of erectile dysfunction due to vascular complications and neuropathy. This risk progressively increases with the patient’s age and duration of diabetes. Psychological causes also should not be overlooked in this age group. The first line of treatment is phosphodiesterase inhibitors (e.g. sildenafil). When treating with phosphodiesterase inhibitors, the following should to be considered.
1.Sildenafil while combining with an alpha-blocker, it is essential to give the drugs with at least 4-hour interval to reduce the risk of hypotension since the half-life of sildenafil is about 4 hours.
2.Sildenafil is contraindicated in patients treated with nitrates.
3.Sildenafil should be used with precaution in conditions predisposing to priapism.
4.Concurrent use of drugs that interfere with the metabolism of sildenafil (e.g. erythromycin, cimetidine) may predispose to adverse reactions by prolonging its plasma half-life. +
'''Correct'''-Any patient with acute and severe illness may have an abnormal thyroid function test. This is sick euthyroid syndrome (low T3 syndrome), which is due to the caloric deprivation and increased cytokine levels during the period of illness. The abnormality pattern is usually a low total or free T3 level with normal T4 and TSH levels, due to decrease in the peripheral conversion of T4 to T3. Longer the duration of illness, T3 fall might be followed by fall in T4 and TSH levels. On recovery from illness there might be a transient increase in TSH levels. For this reason, a thyroid test is usually not performed in severely ill patients unless there is a strong indication, since these abnormalities can be misleading. +
'''Correct'''-Self-induced water intoxication should always be considered in the differential diagnosis of confusional states and seizures in schizophrenic patients. As many as 20% of patients with a diagnosis of schizophrenia drink excessive amounts of water. At least 4% of these patients suffer from chronic hyponatremia and recurrent acute water intoxication. They typically have low plasma and urine osmolality. +
'''Incorrect'''-Periodic stimulated serum calcitonin measurement was previously used to diagnose early medullary thyroid carcinoma before the advent of genetic tests. It is a labor intensive and time consuming test. It is still used to identify residual medullary thyroid carcinoma after thyroidectomy. +
'''Incorrect'''-Metabolic alkalosis do occur due to high aldosterone induced renal reabsorption of bicarbonate. But this is again not specific for the diagnosis. +
Alport syndrome is not primarily associated with abnormal values of alanine aminotransferase (ALT) or liver abnormalities. +
'''Correct''' : Apathetic thyrotoxicosis is an atypical though not rare manifestation of hyperthyroidism that requires high level of suspicion and could be ruled out through thyroid function tests. +
'''Correct''' : Normal insulin dose on the night before surgery, and start the patient on an insulin drip and infusion of D5 1/2NS with 40 mEq of KCL to keep the blood glucose below 160 mg/dl would be the best option for controlling the patient diabetic status +
