The healthcare provider prescribes streptomycin 200 mg IM every 12 hours. The vial is labeled, "Streptomycin 1 gram/2.5 mL." How many milliliters should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["0.5"]
To find out how many milliliters the nurse should administer, we first need to calculate the volume required to deliver 200 mg of streptomycin.
Given:
Streptomycin concentration: 1 gram/2.5 mL
Dose prescribed: 200 mg
We'll start by converting the dose prescribed from milligrams (mg) to grams (g) since the concentration is given in grams:
200 mg = 0.2 grams
Now, we can set up a proportion to find the volume (x) needed to deliver 0.2 grams of streptomycin:
1 gram / 2.5 mL = 0.2 grams / x
Cross-multiplying:
1 * x = 0.2 * 2.5
x = 0.5 mL
So, the nurse should administer 0.5 milliliters of streptomycin.

Correct Answer is C
Explanation
Correct answer: C
A. Irrigate the nasogastric tube with water:
This option is not the best immediate action when a client is choking after vomiting. While irrigating the nasogastric tube with water may help clear the tube itself, it does not directly address the choking episode or potential airway obstruction. The priority in this situation is to ensure the client's airway is clear and maintain their safety.
B. Perform oropharyngeal suctioning:
While suctioning might be used later to clear the airway of secretions, it's not the first-line intervention when someone is actively choking. Suctioning can stimulate the gag reflex and worsen vomiting..
C. Elevate the head of bed 45 degrees:
The primary concern is preventing aspiration (inhaling vomit) which can lead to serious complications. Elevating the head of the bedhelps keep the head and neck in a position that promotes drainage of fluids and reduces the risk of aspiration.
D. Review the advance directive document:
Reviewing the advance directive document is important for understanding the client's wishes regarding their healthcare decisions, but it is not the appropriate action in the immediate management of a choking episode. Ensuring the client's safety and addressing the choking episode take precedence over reviewing documentation.
