A nurse is preparing to administer cefacior to a preschooler who weighs 20 kg. The child is to receive cefacior 30 mg/kg/day to divide equally every 8 hr. Available is cefaclor suspension 125 mg/5 mL. How many mL should the nurse administer for one dose? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["8"]
To calculate the dose;
Weight= 20kg
Dose = 30mg/kg/day 8 hourly
Dose per day = 2030= 600mg
8hourly dose= 600/3= 200mg
Volume to give
125mg= 5ml
200mg = 2005/125
= 8ml

Correct Answer is A
Explanation
A. This hernia is a normal variation that resolves without treatment: Umbilical hernias are common in infants and usually resolve on their own by around 1 to 2 years of age without any specific treatment.
B. An abdominal binder can be worn daily to reduce the protrusion: Using an abdominal binder is not recommended for treating umbilical hernias in infants, as they typically resolve spontaneously and do not require intervention.
C. Restrictive clothing will be adequate to help the hernia go away: Restrictive clothing is not necessary and will not affect the resolution of an umbilical hernia in infants.
D. The quarter should be secured with an elastic bandage wrap: Securing a quarter over the umbilicus with an elastic bandage wrap is not an appropriate treatment for an umbilical hernia and may cause harm.
Correct Answer is C
Explanation
A. Conversion of the PPD test from negative to positive indicates exposure to tuberculosis but does not contraindicate the administration of isoniazid. It may actually indicate the need for prophylactic treatment.
B. A history of intravenous drug abuse is not directly related to the administration of isoniazid. However, it may be important for assessing risk factors for tuberculosis transmission and adherence to treatment.
C. Isoniazid can cause hepatotoxicity, so it is essential to assess for pre-existing liver conditions such as hepatitis B before administering the medication. Hepatitis B may increase the risk of liver damage associated with isoniazid.
D. The length of time of exposure to tuberculosis is important for assessing the risk of infection and determining the need for prophylactic treatment but does not impact the administration of isoniazid.
