Answer:
Pallor
Fatigue
Easy bruising
Cyanosis
When symptoms begin, a child appears pale, fatigues easily, and has anorexia from the lowered RBC count and tissue hypoxia. Because of reduced platelet formation (thrombocytopenia), the child bruises easily or develops petechiae (pinpoint, macular, purplish-red spots caused by intradermal or submucous hemorrhage). A child may have excessive nosebleeds or gastrointestinal bleeding. As a result of a decrease in WBCs (neutropenia) a child may contract an increased number of infections and respond poorly to antibiotic therapy. Observe closely for signs of cardiac decompensation such as tachycardia (not bradycardia), tachypnea (not bradypnea), shortness of breath, or cyanosis from the long-term increased workload of all these effects on the heart.

Answer:
The correct option is : a. causing threshold to be reached more quickly
Explanation:
Norepinephrine, also known as noradrenalin, is an organic compound, which belongs to the catecholamine family. It acts as a hormone and a neurotransmitter in the brain and the body and also impacts the heart.
It is one of the hormones secreted by the adrenal medulla. Norepinephrine is a part of the fight-or-flight mechanism of the body. It acts by binding to the β-1 receptors and opens the chemical or ligand gated calcium and sodium ion channels. Therefore, <u>it causes the threshold to be reached faster </u>by increasing the rate of depolarization and thus causes heart arrhythmia.
Therefore, <u>Norepinephrine acts on the heart by </u><u>causing threshold to be reached faster.</u>
The nursing action that reduces the risk of falling as a patient is getting into or out of a bathtub is to place a skidproof disposable bath mat in front of the tube.
<h3>What is a skidproof disposable bath mat?</h3>
A skidproof disposable bath mat is a functional material that is made up of quick-dry microfiber surface which helps to provide friction for wet surfaces of the bathroom.
It is the duty of the nurse to educate the patient on various measures to take in order to prevent any impending harm.
Therefore, to prevent or reduce the risk of falling in the bathtub, the nurse should place a skidproof disposable bath mat in front of the tube.
