Pepito is trying to isolate a very rare bacteria (Coronacation indefinitus) for research purposes. The prevalence of the bacteria is roughly 1 in 10,000 bacteria. If Pepito performs a serial dilution, which test tubes in the dilution gradient are most likely to contain the bacteria of interest?

The nurse cares for a client recently admitted to the emergency department (ED).  The client reports chest pain.  In which time frame must the nurse obtain an electrocardiogram (ECG), after the client’s report of chest pain?

The nurse cares for a client diagnosed with myocardial infarction (MI). The right atrial pressure (RAP/CVP) is 5 mm Hg, the pulmonary artery wedge  (PAWP) pressure is 20 mm Hg.  The client reports shorness of breath.  Oxygen saturation is 91% on room air and inspiratory crackles are auscultated bilaterally.  Blood pressure is 190/110 mm Hg.  Heart rate is 124.  Which does the nurse suspect?

When stained properly Gram-negative bacteria stain pink always, whereas, Gram-positive bacteria stain purple always. 

Which of the following is caused by partial obstruction of one or more coronary arteries

The nurse cares for a client diagnosed with an anterior wall infarction. Occlusion of which coronary artery would the nurse anticipate being the cause of this infarction?

When the agonist alone is given the patient experiences bradycardia, an increase in diastolic blood pressure, and pupil dilation.  After the antagonist, the agonist produces no alteration in normal heart rate, a decrease in diastolic blood pressure, and no pupil dilation. The antagonist is:
