Answer and Explanation

The Correct Answer is ["0.5"]

· Convert grams to milligrams: 1 gram = 1000 mg

· Determine the concentration: The vial contains 1000 mg of streptomycin in 2.5 mL of solution.

· Set up a proportion: (Desired dose / Concentration) Volume = Amount to administer

(200 mg / 1000 mg) x 2.5 mL = X mL

· Solve for X: 0.2 x 2.5 mL = 0.5 mL

Correct Answer is ["2.5"]

Explanation

Convert mcg to mg: 1 mg = 1000 mcg, so 125 mcg = 125/1000 = 0.125 mg

· Set up a proportion: (Desired dose / Concentration) = Volume to administer

0.125 mg / 0.05 mg/mL = X mL

· Solve for X: X = 2.5 mL

A. Check for neck vein distention. B. Auscultate heart sounds. C. Measure oxygen saturation. D. Determine pulse pressure.

Correct Answer is C

Explanation

A. Check for neck vein distention is important for assessing cardiovascular status, but it is not the first priority when accessory muscle use indicates potential respiratory distress.

B. Auscultate heart sounds is a useful assessment for cardiac issues but does not directly address the immediate concern of respiratory effort and oxygenation.

C. Measure oxygen saturation is the first priority because accessory muscle use suggests increased respiratory effort, which may indicate hypoxemia. Measuring oxygen saturation provides immediate information about the client’s oxygenation status and guides further interventions.

D. Determine pulse pressure is not directly relevant to the observation of accessory muscle use and would not address the immediate respiratory concern.
