A patient with a history of asthma is admitted to the emergency department with severe wheezing, shortness of breath, and retractions. After initial administration of albuterol via nebulizer, the patient's symptoms persist. What is the next best course of action for managing this patient's asthma exacerbation?
Initiate intravenous corticosteroids
Provide supplemental oxygen and reassess in 30 minutes.
Administer a second dose of albuterol immediately.
Administer an oral antihistamine to reduce airway inflammation.
The Correct Answer is A
A. Intravenous corticosteroids are the next appropriate step to reduce inflammation in the airways and improve symptoms of asthma exacerbation.
B. Providing supplemental oxygen and reassessing in 30 minutes might be necessary, but corticosteroids are the priority in this case to address the underlying inflammation.
C. A second dose of albuterol may be considered, but corticosteroids should be administered as soon as possible to treat the inflammation in the airways.
D. An oral antihistamine is not indicated for asthma exacerbations, as it does not target the underlying inflammation in the airways.

Correct Answer is D
Explanation
A. A blood glucose level of 140 mg/dL is too low for DKA, which typically involves hyperglycemia above 250 mg/dL.
B. A blood glucose level of 180 mg/dL and normal ketone levels are inconsistent with DKA, as DKA involves both high glucose and elevated ketones.
C. A blood glucose level of 250 mg/dL with normal ketone levels would not suggest DKA. Elevated ketones are a critical part of diagnosing DKA.
D. A blood glucose level of 600 mg/dL with elevated ketone levels in blood and urine confirms DKA, a life-threatening complication of Type 1 diabetes.
Correct Answer is ["A","C","D","G"]
Explanation
A. Smoking can exacerbate GERD symptoms. It weakens the lower esophageal sphincter (LES), increasing the likelihood of acid reflux.
B. GERD is not primarily caused by excessive production of stomach acid. It is usually due to a failure of the lower esophageal sphincter to prevent the backflow of stomach contents into the esophagus.
C. GERD is caused by the relaxation of the lower esophageal sphincter. When the LES is weakened or relaxes abnormally, acid can reflux into the esophagus, causing symptoms.
D. Elevating the head of the bed can help reduce GERD symptoms. It helps to prevent acid from moving back into the esophagus during sleep.
E. A diet high in citrus fruits is not recommended for GERD management. Citrus fruits can aggravate acid reflux symptoms.
F. Antibiotics are not the first-line treatment for GERD. Proton pump inhibitors (PPIs) or H2 blockers are typically used to manage GERD symptoms.
G. Obesity is a risk factor for GERD. It can increase intra-abdominal pressure, which may contribute to the reflux of acid into the esophagus.
