The nurse is preparing to administer IV fluids to the 13-kg child who has dehydration. The daily IV fluid requirement is to administer 1000 mL / 50 mL/kg over 10 kg. How many milliliters per hour should the nurse calculate to administer the IV therapy correctly?
Correct Answer: 48
Rationale: This child weighs 13 kg; the daily requirement is 1000 mL + (50 mL x 3) = 1150 mL/24 hr. The hourly rate is 1150 mL/ 24 hr = 47.9167 mL/hr, rounded to 48 mL/hr.
Question 2 of 5
The LPN is caring for a client newly diagnosed with HIV. Which statement made by the client regarding antiretroviral therapy (ART) would require correction from the nurse?
Correct Answer: D
Rationale: The World Health Organization (WHO) recommends making treatment for those with a CD4 count of ≤ 350 cells/mm3 a priority, as early intervention can help delay disease progression. Studies have shown that ART can reduce HIV transmission to sexual partners by up to 96%. Conditions such as pregnancy and Hepatitis B and C increase the need to initiate therapy sooner and are in no way contraindicated. ART does not cure HIV, but to maintain viral suppression, it should be continued indefinitely.
