"A patient is preparing to take aspirin 650 mg PO. Available is aspirin 125 mg tablets. How many tablets should the patient administer?" (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["5"]
Step 1: Identify the prescribed dose and the dose per tablet. The prescribed dose is 650 mg and the dose per tablet is 125 mg.
Step 2: Divide the prescribed dose by the dose per tablet to find out how many tablets are needed. So, 650 mg (prescribed dose) ÷ 125 mg/tablet (dose per tablet) = 5.2 tablets
Since we need to round to the nearest whole number, 5.2 tablets rounds to 5 tablets.

Correct Answer is B
Explanation
Choice A reason: A pH of 7.39 is near the lower end of the normal range (7.35-7.45) and would not typically indicate respiratory acidosis.
Choice B reason: A pH of 7.31 is below the normal range, indicating an acidic environment, which is consistent with respiratory acidosis.
Choice C reason: A pH of 7.48 is above the normal range, indicating a more alkaline environment, which would suggest respiratory alkalosis, not acidosis.
Choice D reason: A pH of 7.50 is also above the normal range and would indicate alkalosis rather than acidosis.
Correct Answer is A
Explanation
Choice A reason: Hyperventilation is a compensatory mechanism in metabolic acidosis where the body tries to decrease carbon dioxide levels to balance the acidity.
Choice B reason: Cold, clammy skin is not a typical manifestation of metabolic acidosis; it may be associated with shock or hypoglycemia.
Choice C reason: Increased blood pressure is not directly related to metabolic acidosis. It can be influenced by various factors, including stress or other underlying conditions.
Choice D reason: Bradycardia, or a slow heart rate, is not a common manifestation of metabolic acidosis. Tachycardia, or a fast heart rate, might be observed instead.
