Dopamine 5 mcg/kg/minute IV is prescribed for a client who weighs 132 pounds. The pharmacy dispenses a 500 mL IV solution of 0.9% normal saline with dopamine 1600 mg. The nurse should program the infusion pump to deliver how many ml/hour? (Enter numeric value only. If rounding is required, round to the nearest tenth)
The Correct Answer is ["5.6"]
Convert pounds to kg 1kg= 2.2 pounds 132pounds= 132/2.2=60kg
Desired dose per minute= 5 mcg/kg= 560=300mcg/min Desired dose per hour= 300mcg60mins= 18000mcg Available dose= 1600mg/500ml
1mg=1000mcg
Available dose = 1600000mcg/500ml Infusion rate:
1600000mcg=500ml 18000mcg=18000500/1600000
= 5.625 mL/hour
Rounded to the nearest tenth: 5.6 ml/hour

Correct Answer is A
Explanation
A. Provide disposable training pants while calming the mother: This option addresses the
immediate need to provide comfort and support to the child and mother. Offering disposable
training pants can help manage the situation while the nurse addresses the mother's distress and educates her about age-appropriate toilet training expectations.
B. Refer the mother to a community parent education program: While parent education programs can be beneficial, they are not the initial action needed in this situation, which requires
immediate intervention to support the child and mother.
C. Suggest that the mother consult a pediatric nephrologist: Referring the mother to a pediatric nephrologist may not be necessary at this point, as wetting accidents are common in young
children during the toilet training process. The nurse should first address the immediate emotional needs of the child and mother.
D. Inform the mother that toilet training is slower for boys: While it's true that toilet training can vary in timing for different children, simply providing this information to the mother may not be sufficient in addressing the distressing situation at hand.
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.
