P wave is the atria “firing”/depolarizing, the QRS complex is the ventricles depolarizing (and the atria are depolarizing while this happens), and the T wave is the ventricles depolarizing. Depolarizing is when it contracts, and repolarizing is when it relaxes and refills.
Answer:
Is a bone marrow biopsy painful? Most people need only local anesthesia, as bone marrow aspiration, in particular, can cause brief, but sharp, pain. Individuals are fully awake during the procedure, but the aspiration and biopsy site will be numbed to reduce pain.
Answer:
The client has to drink 1,350 mL between 7 a.m. and 10 p.m.
Explanation:
The answer requires a bit of problem solving analysis.
The client has to receive 1,800 mL in one day (24 hours).
<em>Between 7 a.m. and 10 p.m., he needs to receive 3/4 of the fluid. </em>This means that you have to calculate the amount of fluid by considering the given factors.
So, 3/4 of 1,800 mL is equivalent to 1,350 mL.<em> You can get this by multiplying 3/4 (0.75) to 1,800 and this will give you an answer of 1,350.</em>
Thus, the amount that the client will drink between 7 a.m. and 10 a.m. is 1,350 mL and the remaining 450 mL (1,800 mL minus 1,350 mL) will be consumed within the remaining time period of 21 hours.
