Depression
A 45-year-old patient reported to the clinic today with the following blood pressure history: 154/96 (previous visit) and 149/96 (current visit). Based on these readings, which of the following statements is most appropriate?

Shake well to suspend the injection solution
administer intravenously over 20 minutes
inject a once-monthly dose over 5 minutes with an on-body infusor

Inhibits sodium and water reabsorption in the distal convoluted tubule by inhibiting the Na/Cl co-transporter
A 50-year-old African American male with a past medical history of hyperlipidemia, hypertension, type 2 diabetes, myocardial infarction (MI) status post stent placement (4 months prior), and depression presents to your clinic for hyperlipidemia management. He does not use any tobacco products and drinks approximately 20 beers in 1 week. He is currently on pravastatin 80 mg daily and tolerating it well.

LZ is a 55-year-old African American male who has been in atrial fibrillation for the last ten days. LZ's past medical history includes STEMI s/p CABG three years ago and diabetes mellitus. This is LZ's first episode of atrial fibrillation. His echocardiogram from one month ago shows an ejection fraction of 50% and no left ventricular hypertrophy. LZ complains of occasional palpitations that occur mostly while he is active (e.g., doing yard work). His current heart rate is 120 bpm, and his blood pressure is 130/85 mmHg. Current medications include aspirin 81 mg daily and metoprolol tartrate 50 mg by mouth twice daily for coronary artery disease, lisinopril 10 mg by mouth once daily for his hypertension and glipizide 5 mg by mouth once daily for his diabetes. Which of the following antiarrhythmic agents is NOT recommended to maintain normal sinus rhythm in LZ?
propafenone
dofetilide
amiodarone
dronedarone
Which of the following is an accurate statement about P2Y12 ADP receptor antagonists?
Clopidogrel only undergoes phase II metabolism to get activated and is a reversible inhibitor of the P2Y12 ADP receptor
Patients who have received Brilinta may not have to wait 5 days if open heart surgery is needed due to its reversible inhibition
Ticlopidine only needs to be dosed once daily but requires monitoring of the CBC due to a risk of agranulocytosis
Effient is metabolized by CYP3A4 to inactive metabolite and causes a reversible inhibition of the P2Y12 ADP receptor

change rosuvastatin to atorvastatin
change metoprolol to verapamil

Patients who are on sacubitril/valsartan therapy have elevated BNP levels
BNP should not be used to assist with diagnosis or exclusion of heart failure (HF) as a cause of symptoms (dyspnea or weight gain)
