Correct Answer is A
Explanation
A. The nurse should review the patient's vital signs as soon as they are done. Even though vital signs can be delegated, the nurse retains accountability for assessing the data, interpreting abnormalities, and determining if further action is needed.
B. The nurse assistant should not be responsible for obtaining vital signs. Nurse assistants can take vital signs if they are properly trained and it is within their scope of practice. However, the nurse remains responsible for interpreting and acting on the results.
C. The nurse is not responsible if the nurse assistant fails to obtain the vital signs. The nurse remains accountable for delegated tasks and must ensure they are completed correctly.
D. The nurse assistant should determine if the patient's vital signs are abnormal. Nurse assistants can report abnormal findings, but they are not responsible for interpreting results or making clinical decisions—this is the nurse’s responsibility.
Correct Answer is ["15"]
Explanation
Calculation:
To determine the volume to administer, use the formula:
Volume = (Dose ordered/ Dose available)× mL per dose
Given:
- Ordered dose = 37.5 mg
- Available concentration = 12.5 mg/5 mL
Volume = (37.5/12.5)× 5mL
= 3× 5mL
= 15mL
Thus, the nurse will administer 15 mL.
