An IV bag of 500 mL solution is started at 1900. The flow rate is 38 gtts per minute, and the drop factor is 10 gtts per mL. At
Ronch [10]

Answer: your bag will finish at 2112.

Explanation: (38gtt/min) × (10gtt/ml).

Cross multiply. (38gtt×1ml) × (1min×10gtt)

This gives you 38/10...and the gtts cancel out so, it's 38ml/10min.

Simplify this to 3.8 ml/min.

Now, 3.8ml/x min = 500 ml.

Take 500/3.8. This gives you about 132 minutes if you round to the nearest minute. 60 min/he means 132 min = 2h12m. 2h12m from 1900 is 2112.

Mandarinka [93]

Answer:

- First, place some gauze pads or a clean cloth on the wound and hold for 10 minutes.

- If the gauze or cloth becomes soaked with blood, without removing it, place another on top and continue pressing for another 10 minutes.

- If the blood does not stop flowing, place the wound raised upwards to avoid excessive bleeding.

While you call an Emergency Ambulance.  

Explanation:

Bleeding usually occurs from a cut or trauma that causes the blood vessels to break.

An arterial hemorrhage occurs when the outflow of blood comes from the circulatory system to the outside caused by the rupture of an artery.

Until the artery closes or the wound is cauterized, blood is likely to continue to flow until the person shows symptoms of confusion, slow heart rate, and shock that ultimately leaves the person to bleed to death.
