<em><u>Answer:</u></em>
<em><u>Answer:The ventricles of the heart have thicker muscular walls than the atria. This is because blood is pumped out of the heart at greater pressure from these chambers compared to the atria. The left ventricle also has a thicker muscular wall than the right ventricle, as seen in the adjacent image</u></em>.
Answer:
There are three main ways of avoiding the spreading of an invasive plant species via manual control. Manual control techniques include activities such as hand-pulling, digging, flooding, mulching, burning, removal of alternate hosts and manual destruction or removal of nests, egg masses or other life stages. These techniques work best on small populations or in areas where chemicals or motorized equipment cannot be used. Manual control efforts must be persistent and several treatments may be needed to reduce or eliminate the target population. If infestations are too pervasive, manual control may become labor intensive and thus not economically feasible. Digging/Hand-pulling: Remove entire root to prevent resprouting. Usually works best with small or young plants, in sandy or loose soils, or when soils are damp. Smothering: Use mulch, black plastic, carpet, or any other impenetrable barrier to cover target plants for at least one growing season. The effectiveness of this technique can be increased by first cutting the target plants and then smothering them. If dealing with a species that produces clones, be sure to cover all stems of the species. Flooding: This is only feasible where water levels can be manipulated to completely cover cut plants for a period of time. The depth of water necessary and the amount of time cut plants should be covered will vary from species to species.
Answer:
Yes, both Coumadin and Heparin can be given at the same time.
Explanation:
Both Coumadin and Heparin can be given at the same time. Heparin is is a blood thinner (anti-coagulant) used to prevent and treat blood clots.The patient has been diagnosed with Deep Vein Thrombosis (DVT) which is the formation of blood clot in a vein located deep in the body (usually the lower thigh or leg). The heparin drip she is being administered will help treat the blood clot
Coumadin is also an anticoagualnt and is used for treating blood clotts. However, it takes days (about 3-4) before the treatment starts to work. It stops the synthesis of the four vitamin K–dependent clotting factors in the liver (factors II, VII, IX, X).
Both Heparin and Coumadin are overlapped for at least five days as they work differently. The Heparin is discontinued after anticoagulation occurs and the client starts to be treated with coumadin.
