A nurse is preparing to administer regular and NPH insulin to a client. Which of the following actions should the nurse take?
Mix the medications in a 3-mL syringe.
Inject air into the regular vial first.
Administer the medications in two separate syringes.
Withdraw the NPH insulin last.
The Correct Answer is D
D. Drawing the NPH last ensures that it does not contaminate the short acting insulin. The regular insulin should be drawn first.
A. Regular and NPH insulin should not be mixed together in a single syringe prior to administration. Mixing them could alter their action profiles and affect their effectiveness.
B. While injecting air into the vial before withdrawing medication helps prevent negative pressure and facilitates easy withdrawal of the medication, it should be done for each vial individually, not specifically for the regular insulin vial.
C. The medication should be drawn up into the same syringe before administration to the patient.

Correct Answer is A
Explanation
A. According to the recommended immunization schedule, the second dose of the MMR vaccine is typically administered at 4 to 6 years of age, before starting school. This booster dose helps ensure long- term immunity against measles, mumps, and rubella.
B. The MMR vaccine is typically administered in two doses: the first dose at 12 to 15 months of age and the second dose at 4 to 6 years of age. There is no need for additional MMR immunizations over the next 2 years if the child receives the recommended doses.
C. While the child may receive additional immunizations at 3 years of age, such as the hepatitis B vaccine, the second dose of the MMR vaccine is typically administered at 4 to 6 years of age, not 3 years.
D. Titer testing is typically not recommended for determining the need for further MMR immunizations in young children. The immunization schedule provides specific recommendations for MMR vaccine doses based on age, rather than individual titers.
Correct Answer is ["2.3"]
Explanation
1 lb = 0.453592 kg (conversion factor)
Weight in kilograms = 152 lb × 0.453592 kg/lb ≈ 68.946 kg
Calculate the total dosage based on the client's weight:
Total dosage = 5 mg/kg × 68.946 kg
≈ 344.73mg
Determine the volume of enoxaparin solution needed based on the concentration provided: Available concentration: 120 mg/0.8 mL
Dosage required: 344.73mg Using the formula:
Volume (mL) = Dosage required (mg) / Concentration (mg/mL)
= 344.73mg / 120 mg/0.8 mL
= 2.3ml
