A 45-year-old male patient complaints of chronic stomach pain and is diagnosed with a Helicobacter pylori infection. The physician decided to initiate triple therapy. Which combination of medications is most appropriate for this treatment?
Ciprofloxacin, Metronidazole and Ranitidine
Amoxicillin, Clarithromycin and Omeprazole
Metronidazole, Tetracycline and Bismuth subsalicylate
Erythromycin, Amoxicillin and Famotidine
The Correct Answer is B
A. Ciprofloxacin, Metronidazole, and Ranitidine: Ciprofloxacin and ranitidine are not recommended for H. pylori treatment. Ciprofloxacin is not typically used, and ranitidine is an H2 blocker, not a proton pump inhibitor.
B. Amoxicillin, Clarithromycin, and Omeprazole: This combination is a standard triple therapy for H. pylori infection. Amoxicillin and clarithromycin are antibiotics, and omeprazole (a proton pump inhibitor) reduces stomach acid to help eradicate the bacteria.
C. Metronidazole, Tetracycline, and Bismuth subsalicylate: This combination is part of quadruple therapy rather than triple therapy. Quadruple therapy is usually reserved for cases resistant to initial treatment.
D. Erythromycin, Amoxicillin, and Famotidine: Erythromycin is not part of standard triple therapy, and famotidine is an H2 blocker, not a proton pump inhibitor.

Correct Answer is C
Explanation
A. Initiation of a high-sodium diet. A high-sodium diet is not indicated in pulmonary embolism management; it could worsen fluid retention and cardiovascular strain.
B. Application of a cast to the affected limb. Casting is not appropriate for pulmonary embolism, as it is not an orthopedic injury. Immobilization could increase the risk of further clot formation.
C. Administration of anticoagulant therapy. Anticoagulant therapy, such as heparin or warfarin, is the primary treatment for pulmonary embolism to prevent further clot formation and allow the body to dissolve the clot.
D. Administration of bronchodilators. Bronchodilators may alleviate respiratory symptoms but do not treat the underlying clot in pulmonary embolism. Anticoagulation remains the primary treatment.
Correct Answer is D
Explanation
A. Elevated blood pressure. Blood pressure typically drops in hypovolemic shock as blood volume decreases.
B. Warm, flushed skin. As hypovolemic shock progresses, skin becomes cool and clammy due to decreased blood flow and compensatory vasoconstriction.
C. Increased urine output. Hypovolemic shock leads to decreased urine output due to reduced renal perfusion.
D. Increased heart rate. An increased heart rate is an early compensatory response in hypovolemic shock as the body attempts to maintain cardiac output.
