A student nurse is studying drugs for anxiety and insomnia.
Which of the following should be avoided as they counteract anxiolytics and sedatives and may worsen anxiety symptoms?
Coffee
Tea
Chocolate
All of the above
The Correct Answer is D
Choice A rationale
Coffee contains caffeine, a stimulant that can increase alertness and counteract the effects of anxiolytics and sedatives. However, not all individuals with anxiety or insomnia need to avoid coffee. Some people may find that they can tolerate a small amount of caffeine without it worsening their symptoms.
Choice B rationale
Like coffee, tea also contains caffeine, which can counteract the effects of anxiolytics and sedatives. However, the amount of caffeine in tea is usually less than in coffee, and some types of tea, such as herbal teas, are naturally caffeine-free.
Choice C rationale
Chocolate, especially dark chocolate, contains small amounts of caffeine. However, the amount of caffeine in chocolate is usually much less than in coffee or tea. Some people with anxiety or insomnia may find that they can tolerate chocolate without it worsening their symptoms.
Choice D rationale
All of the above (coffee, tea, and chocolate) contain caffeine, which can counteract the effects of anxiolytics and sedatives and may worsen anxiety symptoms. Therefore, individuals taking these medications for anxiety and insomnia should be advised to avoid or limit their intake of these items.

Correct Answer is B
Explanation
The correct answer is B. 10 units of Humulin R insulin in a 500-unit insulin syringe.
Choice A rationale: This choice is incorrect because a 100-unit syringe would not be able to hold enough U-500 insulin (5 times more concentrated) to deliver the prescribed 10 units. Using a 100-unit syringe could lead to an inaccurate dose.
Choice B rationale: This choice is correct. U-500 Humulin R insulin is a concentrated form containing 5 times more insulin per milliliter compared to U-100 insulin. Therefore, a 500-unit syringe is appropriate to measure the prescribed 10 units accurately.
Choice C rationale: This choice is incorrect. A 30-unit syringe would not have the capacity to hold even the 10 units of U-500 insulin. It would be impossible to draw up the correct dose with this syringe size.
Choice D rationale: This choice is incorrect. Similar to choice A, a 50-unit syringe is not suitable for U-500 insulin due to its limited capacity. It would lead to an inaccurate measurement of the 10-unit dose.
Correct Answer is D
Explanation
Step 1:
1000 mL ÷ 5 hours = 200 mL/hour
Step 2:
200 mL/hour ÷ 60 minutes = (200 ÷ 60) mL/minute = 3.33 mL/minute
Step 3:
3.33 mL/minute × 15 drops/mL = 49.95 drops/minute
Answer:
200 mL/hour and 50 drops/minute (rounded to the nearest whole number)
