Answer: The volume in ml that should be drawn is 2.4ml.
Explanation:
Heparin is an anticoagulant which is administered to prevent the formation of blood
clot in high risk patients. The high risk patients include those undergoing open-heart surgery, bypass surgery, kidney dialysis, and blood transfusions. This medication can be administered subcutaneously ( that is, under the skin) by a health care provider. The exact dosage should be administered to avoid adverse effects.
From the question given,
In 5 ml of stock ampoules, there are 25,000 units.
To calculate how many millilitres will deliver 1 unit, divide by 25,000
5 ÷ 25000 = 0.0002
Therefore 0.0002 ml will deliver 1 Unit.
To calculate the volume that will deliver 12,000 units, multiply by 12,000.
Therefore,
12,000 × 0.0002 = 2.4mL
From the calculation, the volume in ml that should be drawn is 2.4ml

Explanation:
Bleeding usually occurs from a cut or trauma that causes the blood vessels to break.
An arterial hemorrhage occurs when the outflow of blood comes from the circulatory system to the outside caused by the rupture of an artery.
Until the artery closes or the wound is cauterized, blood is likely to continue to flow until the person shows symptoms of confusion, slow heart rate, and shock that ultimately leaves the person to bleed to death.
Answer:
For heart disease and hypertension: Because they contain NSAIDs. It can raise blood pressure and cause other related problems.
For glaucoma: Because is a selective alpha-1 adrenergic receptor agonist, which can induce angle closure by mydriasis. People with glaucoma have narrow drainage angles.
For urinary retention: It can cause urinary retention because of its systemic action on α-adrenergic receptors.
The nurse is teaching a patient who is diagnosed with aortic stenosis the importance of attempting to relieve the symptom of angina without drugs, so the nurse should teach the patient to rest and relax before taking nitroglycerin.
<h3>What is nitroglycerin?</h3>
Nitroglycerin is used to prevent chest pain (angina) that is caused by coronary artery disease. In addition, nitroglycerin is used to relieve an angina attack that is already occurring.
This medicine belongs to the group of nitrates (vasolidator medications). Nitroglycerin works by relaxing the blood vessels and increasing the supply of blood and oxygen to the heart while reducing its work load. When it is used regularly on a long-term basis, or right before exercise or a stressful event, it helps prevent angina attacks from occurring.
