A healthcare provider orders atropine sulfate 400 mcg IM as a preoperative medication. The medication is provided as 0.1 mg/mL. How many mL should the nurse administer?
2 mL
3 mL
4 mL
5 mL
The Correct Answer is C
The ordered dose is 400 mcg, which is equal to 0.4 mg..
The medication is provided as 0.1 mg/mL, so to administer 0.4 mg, the nurse needs to give:.
0.4 mg ÷ 0.1 mg/mL = 4 mL.
Therefore, the nurse should administer 4 mL of atropine sulfate.

Correct Answer is D
Explanation
According to the web, the abdomen is the preferred site for insulin injection because insulin is absorbed more quickly and predictably there.
This helps to maintain a stable blood glucose level and avoid hypoglycemia or hyperglycemia.
The other choices are not answers because:
Choice A (it is the least painful location for this injection) is incorrect because pain depends on various factors, such as needle size, injection technique, and individual sensitivity. The abdomen may not be the least painful location for everyone.
Choice B (it causes less bruising at the site) is incorrect because bruising can occur at any injection site if the needle damages a blood vessel. The abdomen does not have less blood vessels than other sites.
Choice C (there are fewer insulin side effects when given in this site) is incorrect because insulin side effects are not related to the injection site, but to the dose, type, and quality of insulin. The abdomen does not reduce the risk of side effects such as allergic reactions, weight gain, or low blood sugar.
Correct Answer is B
Explanation
Choice A:One tablet contains 500 mg, which is far below the prescribed dose of 15 g/day. Administering one tablet daily would only provide 500 mg/day, which is insufficient.
Choice B:Each dose of 2 tablets provides 1000 mg (1 g), and giving this dose three times daily totals 3000 mg (3 g/day). This is significantly less than the required 15 g/day.
Choice C:Half a tablet would provide 250 mg/day, which is far below the prescribed dose of 15 g/day. This is inadequate and does not meet the prescription requirements.
Choice D:Each tablet contains 500 mg, so 4 tablets provide 2000 mg (2 g). Administering 4 tablets every 8 hours (three times daily) totals 12 tablets/day, which equals 15,000 mg (15 g/day) and fulfills the prescription accurately.
