How many units is the arrow pointing to on the syringe below? Enter numeric value only
The Correct Answer is ["35"]
Insulin syringes are commonly marked in units rather than milliliters (mL). If it's a U-100 insulin syringe, each marking represents 1 unit. The plunger in the image above is at 35 indicating 35 units of insulin.

Correct Answer is D
Explanation
A. While morphine may be indicated for pain management, particularly if the pain is severe, the priority is first to assess the cause of the chest pain. Chest pain in a patient with myxedema could be related to a number of serious conditions, such as a myocardial infarction or worsening cardiovascular issues, so it is important to assess the pain thoroughly before administering any medications.
B. Stopping thyroid hormone administration is not the correct action. Myxedema is a severe form of hypothyroidism, and thyroid hormone therapy is essential in treating this condition. However, if there is a concern about the cause of the chest pain (such as a heart attack), stopping the thyroid hormone might not be appropriate unless directly indicated by a physician.
C. While obtaining cardiac enzymes can be an important diagnostic step if the chest pain is suspected to be related to a cardiac event, the priority at this moment is to assess the pain and clinical presentation more thoroughly. Cardiac enzymes can be checked after a full assessment of the symptoms.
D. The first priority is to complete a comprehensive pain assessment. The nurse should assess the quality, intensity, and duration of the chest pain and ask relevant questions to determine if the pain is cardiac in nature (e.g., tightness, radiating to left arm, sweating) or possibly related to the thyroid condition (e.g., could be related to complications of myxedema, such as hypothyroid-induced cardiac dysfunction). This step is critical to understanding the cause and ensuring appropriate next steps for care.
Correct Answer is ["15"]
Explanation
- The desired insulin infusion rate is 15 units per hour.
- The concentration of the insulin solution is 100 units in 100 mL.
- This means there is 1 unit of insulin in every 1 mL of the solution (100 units ÷ 100 mL = 1 unit/mL).
- To find the milliliters per hour to administer, we need to deliver 15 units per hour, and since there is 1 unit per mL, the flow rate will be: 15 units/hr ÷ 1 unit/mL = 15 mL/hr
