Physical examination reveals a thin man generic viagra plus 400 mg overnight delivery, sitting upright, breathing rapidly on 2 L of 22 BOARD REVIEW oxygen. His vital signs include the following: temperature, 98. Cardiac examination reveals normal rate and rhythm without murmur, and neck veins are not elevated. ECG shows normal sinus rhythm with occasional premature ventricular contractions and ST segment elevations of 0. Which of the following interventions is NOT indicated for this patient at this time? Streptokinase Key Concept/Objective: To understand the initial management of acute MI This patient meets criteria for acute MI with a characteristic history and ECG changes. Emergent therapy should include oxygen, aspirin, analgesia, nitrates, beta blockers, and early reperfusion. The prophylactic administration of antiarrhythmic agents in the absence of significant arrhythmias does not reduce mortality and may actually increase mortality through increased incidence of bradyarrhythmias and asystole. The patient in Question 38 receives thrombolytic therapy with streptokinase within 30 minutes of the onset of his chest pain. Soon after administration of streptokinase, the ECG changes revert to baseline. He is monitored on telemetry for 48 hours without any arrhythmias. He is able to walk around the ward without difficulty.
Fewer than 5% of patients are afebrile buy viagra plus 400 mg line; such patients are often elderly, markedly malnourished, or azotemic. Fever and other nonspecific symp- toms in the presence of a predisposing cardiac lesion may be the only clinical manifes- tations of SBE in some patients. In most patients with SBE, blood cultures drawn before initiation of antibiotic therapy are positive, reflecting the sustained bacteremia associ- ated with an infected endothelial surface. Factors associated with an increased risk of embolization include vegetations of 10 mm or more in size as seen on echocardiogra- phy; vegetations on the mitral valve, particularly the anterior leaflet; vegetations that increase in size during therapy; and infection by Staphylococcus aureus. The incidence of arterial emboli decreases about 10-fold during the initial 2 weeks of antimicrobial therapy. A 35-year-old man presents in the urgent care clinic complaining of fever. He reports that for the past 2 days, he has been experiencing subjective fever, shaking chills, and pleuritic chest pain. The patient denies having any underlying medical conditions. Results of physical examination are as follows: temperature, 103. The neck veins are flat, and the heart is tachycardic with a short systolic ejection murmur that is louder on inspiration. For this patient, which of the following statements about infective endocarditis in intravenous drug users (IDUs) is true? The mitral valve is the most commonly involved valve B. The majority of IDUs who develop endocarditis have preexisting valvular heart disease C.
This patient’s clinical presentation and history are most consistent with which of the following hair disorders? Cicatricial alopecia Key Concept/Objective: To know the clinical presentation of telogen effluvium Telogen effluvium is the most common form of diffuse alopecia buy viagra plus 400 mg line. It presents as a general- ized shedding of telogen hairs from normal resting follicles. The basic cause of telogen effluvium is a premature interruption of anagen, which leads to an increase in the num- ber of hairs phased into telogen. When the 3-month telogen period ends, new anagen hairs grow in and numerous telogen hairs fall out. Patients may need reassurance that this apparent loss of hair is actually a sign of regrowth. Acute telogen effluvium can be caused by childbirth, febrile illnesses, surgery, chronic systemic diseases, crash diets, traction, severe emotional stress, and drug reactions. During acute telogen effluvium, pull tests are positive all over the scalp, yield- ing two to 10 club hairs. Telogen effluvium is often accompanied by bitemporal recession; this is a useful diagnostic sign in women. The diagnosis is usually made on the basis of the history of an initiating event 3 months before the onset of shedding. No treatment is needed for acute telogen effluvium, because the hair invariably regrows within a short time. Alopecia areata is characterized by patchy areas of hair loss, not the diffuse hair loss seen in this patient.
