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 D
Explanation
A. How many popsicles are available.
This information might be helpful for logistical purposes or to assess how much the child has consumed, but it's not directly relevant to ensuring the appropriateness of the popsicles for a clear liquid diet.
B. If the popsicles are completely frozen.
While it's important that popsicles are properly frozen to avoid potential choking hazards, this does not address whether the popsicles meet the dietary requirement of clear liquids.
C. The color and flavor of gelatin used.
While this might be of interest, the key concern is whether the popsicles contain any non-clear components like fruit or pulp.
D. Whether they contain pulp or fruit.
For a child who needs clear liquids, it is important to ensure that the popsicles do not contain any solids like fruit or pulp. Clear liquids are meant to be easily digestible and not irritate the stomach further. Popsicles with pulp or fruit can be too heavy and might not be appropriate in this situation.
Correct Answer is B
Explanation
A. Regular exercise:
Regular exercise is important for overall cardiovascular health and can help reduce the risk of developing heart disease. However, smoking cessation is more crucial because smoking is a significant risk factor for heart disease and quitting smoking has immediate and long-term benefits for heart health.
B. Smoking cessation:
Smoking is a major risk factor for heart disease as it damages the blood vessels, increases blood pressure, reduces oxygen supply to the heart, and promotes the formation of blood clots. Encouraging smoking cessation is essential for reducing the risk of heart disease and improving overall health.
C. Low-fat diet:
Adopting a low-fat diet can help lower cholesterol levels and reduce the risk of heart disease, but it may not be as critical as smoking cessation for individuals with a family history of cardiac disease.
D. Stress reduction:
While stress reduction techniques such as relaxation exercises, meditation, and mindfulness can be beneficial for heart health, addressing smoking cessation is more urgent for individuals with a family history of cardiac disease, as smoking is a more significant risk factor for heart disease.
