Papillary muscles, attached via chordae tendineae, help to close the valves and prevent regurgitation.
Pectinate muscles are parallel ridges in the walls of the atrium of the heart, mainly in right atrium. They can stretch during adverse loading conditions, to <em>help the right atrium to dilate without much wall stres</em>s.
Answer:
231 ml
Explanation:
Let x represent the amo unt of Dextrose 70% in ml and y represent the amount of Dextrose 5% in ml needed to prepare 1,000mL of Dextrose 20%.
Since 1000 ml of Dextrose 20% is needed, hence:
x + y = 1000 (1)
Also 70% Dextrose is mixed with 5% dextrose to produce 20% dextrose. i.e.:
70% of x + 5% of y = 20% of 1000
0.7x + 0.05y = 200 (2)
We have to solve equations 1 and 2 simultaneously.
Let us multiply equation 2 by 20:
14x + y = 4000 (3)
subtract equation 1 from 3:
13x = 3000
x = 231 ml
Put x = 231 in equation 1 to find y:
231 + y = 1000
y = 769 ml
Therefore 231 ml of Dextrose 70% must be mixed with 769 ml of Dextrose 5% to prepare 1,000mL of Dextrose 20%? *

Answer:
3 Monitor intake and output
Explanation:
This client is admitted for heart failure and acute pulmonary edema, which means that his/her heart is not pumping blood as it should, and that there's liquid in the lungs, causing the client symptoms such as dyspnea (shortness of breath).
IV Furosemide, a loop diuretic is prescribed. This drug increases renal excretion of water and electrolytes out of the body, resulting in the mobilization of excess fluid from the body and a decrease in blood pressure. The indication to give the client a second dose of furosemide in an hour is because of its delayed effect.
Since furosemide causes liquids to exit the body, it is important to monitor fluid balance in order to evaluate the effectiveness of this medication. Monitoring fluid balance refers to observing and registering all liquids that come in (IV, orally) and out (urine) of the body. For the client, being admitted to the hospital and receiving IV medication, the nursing personnel should be registering all the liquids the client is receiving (IV and orally) and voiding (urine).
