A. Active vitamin D (calcitriol) and vitamin D analogs (paricalcitol and doxercalciferol) may worsen hypercalcemia in this pt through increased GI absorption and are not recommended until the calcium levels are lowered. Cinacalcet works to decrease secretion of PTH and does not cause hypercalcemia (risk hypocalcemia). This agent is approved only in pts w/ CKD on HD so would be appropriate in this case. Vit D should be considered when this pt's calcium lvls are within normal range. Ergocalciferol is a vit d precursor that requires activation by the kidney and would not be recommended as the sole vit d agent for a pt with stage 5ckd w/o the necessary activity of the enzyme in the kidney responsible for final conversion to the active form. Ergocalciferol would also carry the risk of hypercalcemia if converted to the active form.

Which of the following is true regarding a pt w/ refractory SE who is placed in a medically induced coma with a barb? A. if the pt is MV, the barb will induce respiratory arrest B. the goal of a coma that is medically induced w/ a barb is to induce burst suppression (isoelectric) on EEF C. if hypotension develops, the pt should be given nitroprusside D. the barbs are not associated w/ di E. a major problem w/ this type of therapy is renal failure

B. The goal is to produce a "flat" EEG. If the pt is mv, the effect of a medication on respiration is not a factor in its administration. Although pentobarb may cause hypotension if given too rapidly, nitroprusside is a vasodilator used to treat hypertension. The barbs are known inducers. A coma that is medically induced w/ a barb does not cause renal failure

Lidocaine will be given as a constant rate infusion for the treatment of ventricular arrhythmia. A plasma conc of 3mcg/mL was decided on as the therapeutic target conc.

B. The maintenance dose MD required to achieve an average ss conc of 50ng/mL for an oral dosing regimen given by MD=Css,av x CL/F The oral clearance CL/F can be determined from the relationship btw dose and AUC CL/F=D/AUC, therefore MD= Css,av x D/AUC=50ng/mLx80mg/962ng*h/mL MD= 50 x 80/ 962 = 4.16mg/h 4.16mg/h x 12hr = 50mg q12

A 30yo schizophrenic pt was receiving quetiapine 3mg BID for 12weeks with very little response. Which recommendation is the best for this pt? A. increase quetiapine dose to 600mg bid B. switch the pt to clozapine C. add risperidone 3mg bid to quetiapine D. add fluoxetine and ECT E. continue current therapy

B. The only antipsychotic proven effective for refractory schizo is clozapine. b/c the pt has had little to no response to quetiapine, raising her quetiapine dose is inappropriate. little evidence supports the use of multiple antipsychotics in the treatment of schizo. Augmenting quetiapine therapy w/ prozac and ECT is inappropriate b/c the pt has had little response to quetiapine. Guidelines for the treatment of schizo recommend two adequate trials of antipsychotic monotherapy before switching the pt to clozapine unless clozapine use is ci or inappropriate for the pt

WHich of the following is correct regarding the treatment of ADHF? A. nesiritide is the agent of choice in pts w/ ADHF and hypotension B. milrinone is preferred over dobutamine in pts receiving concomitant BB therapy C. absorption of oral loop diuretics is increased D. dobutamine and milrinone improve survival E. verapamil reduces volume overload and improves CO

B. The positive inotropic effect of milrinone is NOT mediated through the B receptor; therefore, its effects are not diminished by concomitant BB therap. Nesiritide is associated with an increased risk of hypotension. No inotropic agents are shown to improve survival. Verapamil is a negative inotrope and would worsen volume status.

A. the drug is secreted and not reabsorbed B. the drug has a pka value of 5 C. the drug has a small volume of distribution D. all of the drug is excreted unchanged by the kidneys (ex: fe=1)

B. Weakly acidic drugs with pka values 3 and 7.5 can be highly unionized in the range of urine pH (5-8), and can thus undergo significant reabsorption if the unionized form is nonpolar. A: No pH sensitivity in renal clearance is expected unless the drug is reabsorbed Eratio <<1). C: Clearance and volume have nothing to do with a drug's likelihood of being affected by changes in urine pH. D. The fraction excreted unchanged says nothing about the mechanisms of renal elimination. However, it is important to note that for drugs with high fe values that are susceptible to changes in urine pH, large changes in the PK of the drug may be observed.

Initiation of lithium requires several baseline lab tests; pregnancy test, ECG, and BP to assess cardiovascular status, thyroid function tests to rule out euthyroid goiter or hypothyroidism, Scr/BUN (lithium is 100% renally eliminated), and CBC with differential to evaluate for leukocytosis. Electrolytes should also be evaluated (decreased sodium can increase lithium lvls). The pregnancy test should not be performed b/c the pt is male. LFTs must be performed prior to initiation of divalproex. Baseline fasting glucose must be performed when prescribing atypical antipsychotics

Margaret Q, (100kg, 26yo) presents to the ED with acute sx of asthma. She recently started smoking again and has been taking oral theophylline for several years. The immediate determination of her theophylline plasma conc results in a lvl of 4mg/L. Theophylline population pk parameters: CL 0.04L/h/kg; V 0.5 L/kg; Therapeutic range: 10-20mg/L What is the appropriate IV LD of aminophylline for Margaret to achieve a target concentration of 12mg/L A. 300mg B. 400mg C. 500mg D. 600mg E. 750mg

C. LD = Css x Vss = (Ctarget - Cpredose) x Vd LD = 12-4mg/L x (0.5L/kg x 100kg)= 400mg theophylline = 500mg aminophylline The LD can be determined on the basis of the target concentration to be achieved and the Vd. The predose lvl of 4mg/L needs to be subtracted from the target conc, b/c the LD has to account for only the conc difference.

A 7yo boy on VA for partial complex seizures w/ secondary generalization that are refractory to phenobarb, phenytoin, carbamazepine, and gabapentin continued to have seizures and was started on lamictal 2weeks ago. Today he presents w/ a diffuse maculopapular erythematous rash with lesions on his lips. Which of the following is correct? A. a rash associated with lamotrigine generally occurs w/in the first few days; hence, the rash is not associated with an anticonvulsant B. the pt should be given diphenhydramine, and lamotrigine should be continue C. lamotrigine should be d/c D. the rash is secondary to drug interaction btw gabapentin and carbamazepine E. all of the anticonvulsants are associated with a life-threatening rash. To prevent SE associated w/ abrupt d/c of the anticonvulsants, the medications should be slowly d/c'd

C. Lamotrigine has FDA boxed warning for severe rash. Because this pt has a diffuse rash and lesions on his lips, lamotrigine should be discontinued. Because the incidence of severe rash may be higher in children than in adults, current practice would be to d/c lamictal and not "treat through" the rash w/ benadryl. Gabapentin does not interact w/ lamictal; however, the combo of valproic acid and lamotrigine is associated with a higher incidence of rash. Although abrupt d/c of an anticonvulsant may induce SE< an anticonvulsant may be abruptly d/c'd in the face of a life threatening event

During nutritional assessment, the measurement of body cell mass includes A. bone B. interstitial fluid C. skeletal muscle D. intravascular fluid E. extracellular fluid solids

A pt who is receiving chronic phenytoin therapy is hospitalized for an elective surgical procedure. Admission labs note that the pt has a phenytoin conc of 8mcg/mL (therapeutic range=10-20mcg/mL) and an albumin conc of 3g/dL. Phenytoin: F=0.2-0.9, CL-variable, <1% excreted unchanged in the urine 88-93% bound to plasma proteins (primarily albumin). Given this information and the therapeutic range of phenytoin, you would recommend that the physician A. decrease dose phenytoin, b/c high-extraction drugs exhibit increased unbound conc with increases in fraction unbound in the plasma B. increase dose rate of phenytoin, b/c low-extraction drugs exhibit increased CL w/ increases in fraction unbound in the plasma C. not change the dose rate of phenytoin b/c low-extraction drugs do not exhibit changes in unbound conc w/ increases in fraction unbound in the plasma D. not change the dose rate of phenytoin b/c low-extraction drugs exhibit equal and offsetting changes in CL and F with increases in fraction unbound in plasma

C. Phenytoin has to be a low-extraction drug b/c its bioavailability is as high as 90%. The large range in F is due to variability in the absorption of the drug. You know it is not high extraction b/c if it were, you could never get an F=90%. Phenytoin is a low-extraction drug and restrictively cleared. Normal albumin ranges: 3.5-5mg/dL. Thus, the pt probably has increased fraction unbound in plasma d/t low albumin levels. Because phenytoin is a low-extraction drug, CL is dependent on Fup and CLint. Increased fup would lead to increased CL and decreased total plasma concentrations.

A. SL NTG PRN B. Inderal C. Zestril and SL NTG PRN D. Cardiezem and SL NTG PRN E. Coreg and SL NTG

D. All pts with chronic chest pain need SL NTG for acute use but SL NTG is not ok as monotherapy. CCB would help control his angina as well as lower his BP. Although BB should be considered first line in pts with stable angina for anti-ischemic effects, CCB can be additive or used in settings where a CI exists. In this case, the pt has asthma so a cardioselective BB is needed. Both inderal (propranolol) and coreg (carvedilol) are not cardioselective. ACEI are not effective as antianginal agents

A 45yo m presents to his local health care provider w/ a complaint of extreme stiffness for the past 2 months that begins in the morning and lasts until noon on most days. he also states that he feels "drained" all the time and that both of his knees are swollen and painful. Also notes rheumatoid nodules. Labs significant for elevated CRP and ESR and +Rh factor. States that he has been taking OTC ibuprofen at a dose of 200mg 2-3x/d w/o relief. Which of the following represents the best drug therapy for this pt?

D. Because of fluoxetine long half-life, 5 weeks should pass before initiating MAOI therapy. If fluoxetine is not cleared from the body by the time the MAOI is started, there is a risk of developing serotonin syndrome

A new anticonvulsant has just been approved by the FDA. It's bioavail>95% and its highly protein bound to a1-acid glycoprotein. It undergoes extensive hepatic metabolism by 2c9. Less than 5% excreted unchanged in urine. It is known to inhibit 3a4. A pt on this anticonvulsant has developed significant depression and is being started on an antidepressant that is 93% bound to albumin and is potent inhibitor of 2c19. The antidepressant is a pro-drug that is metabolized by 3a4 to an active metabolite that is hepatically cleared by 2c9. The neurologist wants to know if any di may occur that would necessitate a change in drug dosage. Which of the following is the appropriate response? A. no drug interactions should occur in this pt B. the dose of the anticonvulsant should be reduced b/c of a potential pr bound interaction that would increase the serum concentration of the anticonvulsant C. the dose of the anticonvulsant should be increased D. the pt may not benefit from the antidepressant, and another antidepressant that is not metabolized by cyp3a4 should be used E. b/c of interaction in the gut that decreases bioavailability, the dose should be increased

D. Because the new anticonvulsant inhibits cyp3a4, D is the correct answer.B/c the antidepressant is a prodrug, which must be metabolized to become active, it may not be effective
