Answer:
Isovolumetric Phase
Explanation:
Heart contraction presents various phases that depend on the volume of blood and pressure present in each chamber. From these variables, one can plot blood volume vs pressure in an x and y axis.
This question describes a phase where all valves are closed and no changes in blood volume is present. This occurs during two parts of the heart cycle called isovolumetric (iso-: same, -volumetric: volume) phase, which can be seen during contraction and relaxation. This phenomen is due to the pressure gradients the ventricle has to overcome to open the valves.
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).
The nurse should tell the parent that the infant should be kept in the harness at all times, even if they are changing the diaper or the clothes of the patient. The nurse should also recommend sponge baths instead of full baths for the baby, and also to keep the baby as dry and clean as possible.
