A hormone carries out a single a single specific function.<br> a. True<br> b. False
agasfer [191]

Answer: False  

Explanation:

A hormone can have multiple function based on the cell on which it is received which means that it depends on the receptor on which the hormone is received.

A single hormone has more than one specific function as it depends on receptors because one hormone can have multiple receptors.

The same can be coupled to different intracellular pathway in the different cell types.  

hence, the given statement is False, a single hormone carries out different function.

Your team is resuscitating a newborn whose heart rate remains less than 60 bpm despite effective ppv and 60 seconds of chest com
Talja [164]

According to the 8th edition, the volume of normal saline flush that you should administer is 3mL.

The administration of epinephrine with normal saline has changed from the 7th edition of neonatal resurrection to the 8th edition.

<h3 /><h3> Epinephrine and normal saline volumes</h3>
  • In the 7th edition volume of normal saline was 0.5 to 1mL depending on the weight.
  • In the 8th edition, the volume increased to 3mL for all newborn's weights.

In conclusion, the intravenous flush of epinephrine and normal saline should be 3mL.

How to calculate the heart rate from the electrocardiogram ?​
Masja [62]

Answer:

ECG paper is a grid where time is measured along the horizontal axis.

Each small square is 1 mm in length and represents 0.04 seconds.

Each larger square is 5 mm in length and represents 0.2 seconds.

Voltage is measured along the vertical axis.

10 mm is equal to 1mV in voltage.

The diagram below illustrates the configuration of ECG graph paper and where to measure the components of the ECG wave form

Heart rate can be easily calculated from the ECG strip:

When the rhythm is regular, the heart rate is 300 divided by the number of large squares between the QRS complexes.

For example, if there are 4 large squares between regular QRS complexes, the heart rate is 75 (300/4=75).

The second method can be used with an irregular rhythm to estimate the rate. Count the number of R waves in a 6 second strip and multiply by 10.

For example, if there are 7 R waves in a 6 second strip, the heart rate is 70 (7x10=70).
