Confirmatory Tests vary, and may be wrong from time to time. As time passes, the test is not as reliable as stated. If the so called "blood" is on a leather surface, blood isn't too prone to sticking to leather, so it may (or may not) be blood.
In the following orbital the lone pair on each N atom is present:
N1: sp3,
N2: p,
N3: p,
N4: sp2,
N5: sp2
Sitagliptin is an anti-diabetic drug used to treat type 2 diabetes and is marketed under the brand names Januvia and others. One carbon atom has no pi bonds, while the first nitrogen atom is linked to two hydrogen atoms. It thus possesses sp3 hybridization.
The second nitrogen atom possesses a single pair of electrons and is bound to three other atoms. It is hence sp2 hybridized. The nitrogen atoms in positions 3, 4, and 5 have sp2 hybridization.
The lone pair of nitrogen in the first nitrogen atom is in the sp3 orbital. The second and third nitrogen atoms' only pair of electrons are in p-orbitals. The fourth and fifth nitrogen atoms' lone pair of electrons are in sp2 orbitals.

An emergency room nurse is speaking with a patient who is exhibiting symptoms of an ischemic stroke that started two hours ago. The client mentions having had a cholecystectomy six weeks prior and using labetalol, digoxin, and warfarin. What element puts the patient's thrombolytic therapy at risk?
What is ischemic stroke?
An ischemic stroke is the loss of brain tissue (cerebral infarction) brought on by insufficient oxygen and blood flow to the brain as a result of an arterial blockage. An artery leading to the brain can get blocked, frequently by a blood clot or a fatty buildup brought on by atherosclerosis, leading to an ischemic stroke.
In patients with ischemic stroke, thrombolytic therapy must be started within three hours. If the patient underwent surgery within the last 14 days, she is not qualified for thrombolytic therapy. Labetalol and digoxin do not preclude thrombolytic treatment.
