How many tablets should a 39 kg patient take every four hours?
PolarNik [594]
50 mg/kg/day x 34 kg = 1700 mg/day
1700 mg/day x 1 day/24 hrs x 4 hrs = 283 mg every 4 hrs

283 mg/4hrs x 1 tablet/400 mg = 0.7 tablets

So to acieve the desired dose, the pati should take seven tenths of a tablet every 4 hours. Thats an unusual dosage since it’s difficult to take 0.7 tablet. The question didnt ask about the liquid suspension so I didn’t include that.

Help me please with this question
lukranit [14]

Answer:

see explanation

Step-by-step explanation:

2B + 3C

= 2 \left[\begin{array}{ccc}4&-5\\-2&1\\\end{array}\right] + 3 \left[\begin{array}{ccc}1&-1\\-6&3\\\end{array}\right]

Multiply each element in the matrices by the scalar quantity, that is

= \left[\begin{array}{ccc}8&-10\\-4&2\\\end{array}\right] + \left[\begin{array}{ccc}3&-3\\-18&9\\\end{array}\right]

Add corresponding elements from each matrix

= \left[\begin{array}{ccc}8+3&-10-3\\-4-18&2+9\\\end{array}\right]

= \left[\begin{array}{ccc}11&-13\\-22&11\\\end{array}\right]
