Answer:

The answer is b. False

Explanation:

Ischemia refers to the detention or decrease in the blood flow through the arteries to a determined area. When this happens, cells located in that area are unable to receive enough oxygen and nutrients, therefore they are susceptible to suffer damage. Depending on the level and duration of the ischemia, the damage can be minor or extremely severe.

Whenever we are in presence of heart ischemia, the heart muscle cells suffer deprivation of oxygen and nutrients, and in consequence the cellular function is altered. Due to this fact, the heart beat and the heart sounds might be affected. Heart ischemia is usually caused by blockage of the coronary arteries. This event is referred as a myocardial ischemic infarction.

High-density lipoproteins (HDLs) transport cholesterol from cells to the liver, where it becomes part of bile. HDLs are ________

Rudik [331]

Answer: HDLs are antiatherogenic lipoproteins....

Explanation:

The anti-atherogenic effect of HDL occurs, above all, because of its properties to carry lipids, mainly cholesterol esters from peripheral tissues to the liver, which is known as reverse cholesterol transport(RCT). However, other protective actions of HDL, in addition to RCT, have been described in several experimental models and epidemiological studies. These actions include antioxidant protection, mediation of cholesterol efflux, inhibition of the expression of cell adhesion, leukocyte activation, regulation of blood coagulation and platelet activity.

a nurse is caring for an infant who has been prescribed a one-time dose of ceftriaxone (rocephin) 50 mg/kg im. the infant weighs

RideAnS [48]

The nurse should administer 0.8 mL ceftriaxone IM.

<h3>How to calculate the value?</h3>

Determine the infant's weight in kg: 2.2 lb / x kg

= weight in lb / 1 kg; 2.2 lb / x kg = 17.6 lb / 1 kg.

Cross multiply and x = 8 kg

Find total of one-time dose:

Amount prescribed x kg weight (mg x kg)

= total daily dose; 50 mg x 8 kg = 400 mg

What is the dose needed?

Dose needed = Desired; Desired = 400 mg

What is the dose available?

Dose available = Have; Have = 500 mg

Set up an equation using knowledge about basic equivalents.

Desired x Quantity / Have

= Amount to be given; 400 mg x 1 mL / 500 mg = x mL; 400 x 1

= 400 ÷ 500 = 0.8 mL
