It is important for the nurse to assess for the use of complementary and alternative medicine (CAM) because:

To find the volume of amoxicillin solution the nurse needs to administer, we can divide the desired dose (300 mg) by the concentration of the solution (250 mg/5 mL).

Here's the calculation:

Amoxicillin volume (mL) = Desired dose (mg) / Concentration (mg/mL) Amoxicillin volume (mL) = 300 mg / 250 mg/5 mL

Since we're dividing by a fraction, it's mathematically equivalent to multiply by the reciprocal of the fraction. The reciprocal of 250 mg/5 mL is 5 mL/250 mg.

Amoxicillin volume (mL) = 300 mg * (5 mL / 250 mg)

Cancel out the milligrams (mg) units:

Amoxicillin volume (mL) = 300 mg / 250 mg * 5 mL

Amoxicillin volume (mL) = 1.2 mL (rounded to one decimal place)

However, since we are dealing with medication, it's best to round to the nearest whole number for accuracy in administering the dose.

Therefore, the nurse should administer 6.0 mL of amoxicillin oral solution.

A. Platelets 74,000/mm: A platelet count of 74,000/mm³ is significantly lower than the normal range (typically 150,000 to 450,000/mm³). This could indicate heparin-induced thrombocytopenia (HIT), a serious adverse effect of heparin therapy where the immune system forms antibodies against heparin bound to platelet factor 4, leading to a decrease in platelets and increased risk of thrombosis. This is a critical finding and should be reported immediately to the provider for further evaluation and potential adjustment of the treatment plan.

B. White blood cell count 8,000/mm³: This is within the normal range (typically 4,000 to 11,000/mm³) and does not indicate an immediate problem related to heparin therapy or pulmonary embolism management.

C. Partial thromboplastin time (PTT) 55 seconds: While slightly elevated, this PTT is within the therapeutic range for a patient receiving IV heparin (typically 1.5 to 2.5 times the normal control value, or about 45 to 70 seconds). This indicates that the heparin is having the desired anticoagulant effect.

D. Hematocrit 45%: This is within the normal range for adults (typically 38-50% for men and 35-45% for women) and does not indicate an immediate concern related to heparin therapy or pulmonary embolism.
