Medicine
1 answer:
Sveta_85 [38]3 years ago
6 0

Answer:

True

Explanation:

Pacemaker cells, unlike other neurons in the body, can depolarized themselves (and therefore can fire action potentials) without the need of an external innervation of the autonomic nervous system.  

Each class of pacemaker cells has its own intrinsic rate.

For example, sinoatrial node rate is 60-100 bpm (the normal heart frequency).  

The atrioventricular node is also part of the electrical conduction system of the heart. When the sinoatrial node fails, atrioventricular node takes the lead (40-60 bpm).

A client is to receive 1,800 mL of fluid during a 24-hour period. The client is to receive 3/4 of the fluid between 7 AM and 10
mart [117]

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.
