Hypokalemia is a common disorder that can negatively affect organ function. Magnesium supplementation is frequently recommended despite limited evidence to support its use. ⋯ Magnesium coadministration during hypokalemia treatment did not affect time to serum potassium normalization but was associated with more hypermagnesemia.

What is the Best Agent for Rate Control of Atrial Fibrillation With Rapid Ventricular Response?
Atrial fibrillation (AF) is a common dysrhythmia associated with significant morbidity and mortality. Although many patients have stable AF, some patients can present with a rapid ventricular response (RVR). In these patients, it is important to lower their heart rate. However, there are several options available for rate control in the emergency department setting. ⋯ Based upon the available literature, diltiazem likely achieves rate control faster than metoprolol, though both agents seem safe and effective. Clinicians must consider the individual patient, clinical situation, and comorbidities when selecting a medication for rate control.

Distribution of Lower Extremity Deep Vein Thrombosis and Implications for Limited Compression Ultrasound Examinations.
Limited compression bedside ultrasonography (LCUS) including two-point, three-point, and extended compression examinations have become increasingly popular among emergency physicians to assess for lower extremity deep venous thrombosis (DVT). ⋯ In our study, a significant number of DVTs were identified in sites that may have been potentially missed on LCUS examinations, thereby supporting the use of complete duplex ultrasonography when available.
