A patient with a severe bacterial infection has been prescribed a continuous IV infusion of an antibiotic at a rate of 5 mg/kg/hour. The patient weighs 72 kg. The pharmacy provides the antibiotic in a concentration of 400 mg/100 mL what will be the infusion rate?

Answer and Explanation

The Correct Answer is ["90"]

Calculate the required dosage: 5 mg/kg/hour × 72 kg = 360 mg/hour.

Determine the volume required based on the concentration: 360 mg ÷ (400 mg/100 mL) = 90 mL/hour.
The correct infusion rate is 90 mL/hour for this patient.

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.

A. Erosion of the gastric mucosa on endoscopy B. Decreased serum amylase levels C. Presence of Helicobacter pylori antibodies in serum D. Hypersecretion of hydrochloric acid

Correct Answer is A

Explanation

A. Erosion of the gastric mucosa on endoscopy is the hallmark of acute gastritis. Chronic alcohol use can irritate and inflame the stomach lining, leading to mucosal erosion, which is commonly seen during endoscopy in patients with this condition.
B. Decreased serum amylase levels are not typically associated with acute gastritis. Amylase levels are more commonly elevated in cases of pancreatitis, not gastritis.
C. The presence of Helicobacter pylori antibodies in serum is more indicative of chronic gastritis or peptic ulcer disease rather than acute gastritis. H. pylori is a long-term cause of gastric inflammation.
D. Hypersecretion of hydrochloric acid is more commonly associated with conditions such as Zollinger- Ellison syndrome and is not a typical finding in acute gastritis caused by alcohol use.
