An infant who weighs 22 pounds receives a prescription for amoxicillin 20 mg/kg/day by mouth in divided doses every 8 hours. The bottle is labeled, "Amoxicillin for Oral Suspension, USP 250 mg per 5 mL." How many mL should the nurse administer with each dose? (Enter numerical value only. If rounding is necessary, round to the nearest tenth.)
The Correct Answer is ["1.3"]
1. Convert the infant's weight from pounds to kilograms. We can use the conversion factor 1 kg
= 2.2 lb. So, 22 lb x (1 kg / 2.2 lb) = 10 kg.
2. Calculate the total daily dose of amoxicillin for the infant. We can use the formula D = d x W, where D is the total daily dose, d is the dose per kg per day, and W is the weight in kg. So, D = 20 mg x 10 kg = 200 mg.
3. Calculate the single dose of amoxicillin for the infant. We can divide the total daily dose by the number of doses per day. Since the prescription is for every 8 hours, there are 3 doses per day. So, 200 mg / 3 = 66.67 mg.
4. Calculate the volume of amoxicillin suspension for the single dose. We can use the ratio of the concentration of the suspension, which is 250 mg per 5 mL. So, 66.67 mg x (5 mL / 250 mg) =
1.33 mL.
5. Round the volume to the nearest tenth= 1.3 mL

Correct Answer is B
Explanation
MRSA is a highly contagious bacteria that can easily spread from person to person through direct contact or contact with contaminated surfaces. By instructing the family to adhere to contact precautions, the nurse can help prevent the spread of MRSA to the client's postoperative wound. Contact precautions typically involve wearing gloves and a gown when in direct contact with the client or the client's immediate environment.
While reporting any increase in the white blood cell count, changing the surgical dressing when soiled, and wearing a face mask during wound care are all important aspects of postoperative care, they are not specifically targeted at preventing the recurrence of MRSA. Adhering to contact precautions is the most effective measure to prevent the spread of MRSA and protect the client from further infection.
Correct Answer is A
Explanation
A) Correct- Zidovudine is an antiretroviral medication used in the treatment of HIV infection.
One of the potential side effects of zidovudine is hematological toxicity, including anemia (low red blood cell count) and neutropenia (low white blood cell count). The appearance of pinpoint, red, round spots on the skin could be indicative of petechiae, which are small hemorrhages caused by the leakage of blood into the skin. Petechiae can occur due to low platelet counts, a
component of the complete blood count (CBC). Monitoring the complete blood count is important for clients receiving zidovudine to identify any potential adverse effects on blood cell counts. Anemia and neutropenia can increase the risk of infection, bleeding, and other complications. Therefore, any changes in blood cell counts, including the presence of petechiae, should be reported to the healthcare provider for further evaluation and management.
B) Incorrect- This is used to assess allergic reactions and is not specifically related to the appearance of petechiae.
C) Incorrect- A skin biopsy is typically performed to diagnose skin conditions or diseases and is not the primary assessment to evaluate the cause of petechiae.
D) Incorrect- Electromyography is a diagnostic test used to assess muscle and nerve function and is not relevant to the appearance of petechiae associated with zidovudine use.
