Explanation
Primary treatment for stenotrophomonas maltophilia is SMX-TMP. Meropenem, ciprofloxacin, Ampicillin and vancomycin have no coverage.

Explanation
A, B - false - dapsone inhibits bacterial synthesis of dihydrofolic acid, via competition with para- aminobenzoate for the active site of dihydropteroate synthetase. Dapsone is both bacteriostatic and weakly bactericidal against M. leprae. Neither of the listed mechanisms are the cause of these effects. C - False - A substance with both anti-leprosy and anti-inflammatory activity, clofazimine is weakly bactericidal against M.
leprae by binding to the guanine bases of bacterial DNA, not DNA polymerase directly. D - False - See below. E - True - Rifampin is bactericidal by inhibiting RNA synthesis by blocking DNA-dependent RNA polymerase.

Explanation
The diagnosis of Zollinger-Ellison syndrome is suggested when plasma gastrin is > 1000 pg/ml and the basal acid output is > 15 mEq/h or when associated with a pH < 2. The treatment is focused on controlling gastric acid hypersecretion and localisation of the tumour and its metastases. Proton pump inhibitors are the most effective antisecretory drugs and can be administered at high dosages

The concentration is the first thing to calculate, using 1 mL of octreotide solution containing a concentration of
0.5mg/mL is really using 0.5mg of octreotide. If this is placed in 50 mL NS then it is 0.5mg/50mL which is
0.01mg/mL or 10 mcg/mL. If the patient needs 50 mcg of octreotide per hour then the patient will need 5, 10 mcg/mL doses or 5 mLs. So the rate for this patient would be 5 mL/hr.

Explanation
Ceftaroline covers MRSA, but it does not cover pseudomonas. Ertapenem does not cover pseudomonas.
Cefazolin does not cover MRSA nor Pseudomonas. Cefepime has pseudomonas coverage. Vancomycin does not cover gram negative bacteria.
