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

Answer and Explanation

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 B

Explanation

A. While anxiety relief is important, holistic care encompasses the patient's overall well-being and not just the alleviation of symptoms.
B. Understanding how anxiety impacts the patient's daily functioning allows for a more comprehensive approach to care, addressing both psychological and practical concerns.
C. It is inappropriate to suggest to the patient that there is little hope for relief, as this can negatively affect their mental health.
D. Focusing solely on quick fixes does not address the underlying issues of chronic anxiety and may not lead to long-term improvements.

A. Decrease in hemoglobin level B. Increase in diastolic filling time C. Increase in stroke volume D. Decrease in cardiac output

Correct Answer is D

Explanation

A. An increase in heart rate does not directly affect hemoglobin levels; this option is incorrect.
B. A higher heart rate decreases diastolic filling time, as there is less time for the heart to fill between beats, which can lead to reduced stroke volume.
C. An increased heart rate does not inherently increase stroke volume; in fact, at very high rates, stroke volume can decrease due to reduced filling time.
D. The significant increase in heart rate to 164 beats/min can lead to decreased cardiac output due to compromised diastolic filling and reduced stroke volume.
