A patient has been prescribed to receive 0.3 mL of U-500 insulin. Which syringe will the nurse use to administer the medication?
3-mL syringe
U-100 syringe
Needleless syringe
Tuberculin syringe
The Correct Answer is D
A. A 3-mL syringe is not appropriate for administering U-500 insulin, as the concentration may not allow for accurate dosing at such a small volume.
B. A U-100 syringe is designed for U-100 insulin and would not provide accurate measurement for U-500 insulin.
C. A needleless syringe may be useful in certain contexts, but it does not specifically provide the necessary precision for insulin dosage.
D. A tuberculin syringe is suitable for administering small doses (like 0.3 mL) and provides more accurate measurement for high-concentration insulin such as U-500.

Correct Answer is C
Explanation
A. Certification relates to additional qualifications and does not directly involve independent nursing actions in patient care.
B. Licensure is the legal permission to practice nursing but does not describe decision-making and action in patient care.
C. Autonomy is demonstrated when the nurse independently assesses the patient’s fluid status and takes action to promote health by encouraging fluid intake. This reflects the nurse’s ability to make decisions and act based on professional judgment.
D. Accountability refers to being responsible for one's actions but does not specifically cover the independent decision-making shown here.
Correct Answer is C
Explanation
A. Elevated blood pressure may occur with various conditions but is not a specific late sign of hypoxia.
B. An increased pulse rate can be an early compensatory response to hypoxia rather than a late sign.
C. Cyanosis, which is a bluish discoloration of the skin and mucous membranes, is a classic late sign of hypoxia, indicating severe oxygen deprivation.
D. Restlessness may indicate early signs of hypoxia or anxiety rather than a late sign and can occur before cyanosis develops.
