Answer:
The plateau phase seen during the action potential of a cardiac muscle cell is due to e. opening of calcium fast channels.
Explanation:
During cardiac contraction, myocardic cells reach a phase called phase 2 in which thanks to the umbral valor that they reach on the previous phase 1, calcium fast channels that are voltage dependent are open. Those fast channels just stay open by a few decimals of seconds. When those channels of calcium are open, a lot of calcium ions get into the cell maintaining depolarization of the myocardic cells. All positive charge that posses the cell due to the previous situation, causes efflux of potassium(an ion which have also a positive charge) like a way to reach a physiologic balance.
Answer:
Therefore 2.5 ml of Lanoxin (digoxin) Pediatric Elixir is to be administered to the child daily
Explanation:
The child weighs 81 pound. The weight of the child is needed to be converted from pound to kg.
1 kg= 2.2 pound
Therefore 81 pound = 81/2.2 kg = 36.8 kg
Since the child is to be administered bases on 3.4 mcg/ kg/day, the volume of Lanoxin elixir qd to be administered to the 81 pound (36.8 kg) in one day = 36.8 kg × 3.4 mcg/ kg/day = 125.12 ≅ 125 mcg
Lanoxin (digoxin) Pediatric Elixir is 50 mcg (0.05 mg)/mL, therefore 125 mcg = 125 mcg / 50 mcg/ml = 2.5 ml
Therefore 2.5 ml of Lanoxin (digoxin) Pediatric Elixir is to be administered to the child daily
