Answer:

- Chemical A binds to and blocks Ach receptors of muscle cells

Explanation:

When the Ach receptor in the neuromuscular terminal is blocked by chemical A, the muscles cells will not receive the impulse from the central nervous system. This is the most common type of drug administered to patients during surgery.

In the case of chemical B, flooding the muscle cells' cytoplasm with Ca2+, will cause exactly the opposite, muscle contraction. The reason for this is that high concentration of  Ca2+ in the cytoplasm is an essential part of the mechanism that triggers muscle contraction.

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.

Heparin 12, 000 units subcutaneous is prescribed. Stock ampoules contain 25, 000 units/ 5ml. What volume in ml should be drawn u
Nutka1998 [239]

Answer: The volume in ml that should be drawn is 2.4ml.

Explanation:

Heparin is an anticoagulant which is administered to prevent the formation of blood

clot in high risk patients. The high risk patients include those undergoing open-heart surgery, bypass surgery, kidney dialysis, and blood transfusions. This medication can be administered subcutaneously ( that is, under the skin) by a health care provider. The exact dosage should be administered to avoid adverse effects.

From the question given,

In 5 ml of stock ampoules, there are 25,000 units.

To calculate how many millilitres will deliver 1 unit, divide by 25,000

5 ÷ 25000 = 0.0002

Therefore 0.0002 ml will deliver 1 Unit.

To calculate the volume that will deliver 12,000 units, multiply by 12,000.

Therefore,

12,000 × 0.0002 = 2.4mL

From the calculation, the volume in ml that should be drawn is 2.4ml
