A nurse is preparing to administer enoxaparin 5 mg/kg subcutaneous daily to a client who has deep-vein thrombosis. The client weighs 152 lb. Available is 120 mg/0.8 mL prefilled syringe. Calculate the dosage in mL that the nurse should administer. (Round the answer to the nearest tenth. Use a leading zero if applicable. Do not use a trailing zero.)
The Correct Answer is ["2.3"]
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: 344.73 mg Using the formula:
Volume (mL) = Dosage required (mg) / Concentration (mg/mL)
= 344.73mg / 120 mg/0.8 mL
= 2.3ml

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 D
Explanation
D. The Quadrivalent human papillomavirus (HPV) vaccine is recommended for both males and females to protect against certain strains of HPV that can lead to cervical cancer, genital warts, and other HPV- related cancers. It is typically administered in a series of doses starting around 11-12 years of age.
A. Hepatitis B vaccine is typically administered at birth, followed by a series of doses at 1-2 months and 6-18 months of age. By the age of 11, the child would have completed the series if they were up to date on immunizations. Therefore, it is unlikely that the child would need another dose of the Hepatitis B vaccine at this age.
B. Rotavirus vaccine is usually administered in infancy, with the first dose given around 2 months of age and the last dose by 8 months of age. By the age of 11, the child would have completed the series if they were up to date on immunizations. So, administering the Rotavirus vaccine to an 11-year-old who is up to date on immunizations is unnecessary.
C. The Pneumococcal conjugate vaccine protects against infections caused by the bacterium Streptococcus pneumoniae, such as pneumonia and meningitis. It is typically administered in infancy, with a booster dose recommended at around 12-15 months of age. However, the CDC recommends a single revaccination dose of Pneumococcal conjugate vaccine for children aged 6 through 18 years who are at high risk of infection. If the child falls into this category, the nurse should plan to administer the vaccine.
