Aclient diagnosed with heart failure presents with a temperature of 99.1° f, pulse 100 beats/minute, respirations 42 breaths/minute, bp 110/50 mm hg; crackles in both lung bases; nausea; and pulse oximeter reading of 89%. which finding indicates a need for immediate attention?

The medical finding of the patient diagnosed with the heart failure demanding the attention of the doctor is the crackles in the both lung bases. This is a sign of the lung congestion. The patient is suffering from the congestive heart failure. The congested lungs are mostly a result of the accumulation of the blood back into the veins taking blood through a person's lungs because the heart is unable to pump it efficiently to the body. The increased pressure in these veins makes the fluid to flow in the alveloi leading to low levels of oxygen making it difficult for the person to breathe.

Hence, the answer is 'lung congestion'.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
