NURS 615 Exam IV/ 81 Q&A/ Already Graded
A+/ 2024-2025.
How will you prescribe lipase, protease, and amylase components? - Answer:
Patients with cystic fibrosis are often prescribed enzyme replacement for
pancreatic secretions each replacement drug has amylase, lipase and protease
components, however the drug is prescribed in units of lipase
What is the medication of choice for hypertensive crisis with pheochromocytoma?
- Answer: Surgical resection of the tumor is the first treatment of choice either my
open laparotomy or laparoscopy either surgical option requires prior treatment of
nonspecific irreversible adrenergic adrenoreceptor blocker phenoxybenzamine or
a shorter acting alpha antagonists, prazosin, terazosin, and doxazosin. Mainly use
phenozibenamine in practice. Doing so promotes the surgery to proceed while
minimizing the likelihood of severe intraoperative hypertension which is likely
when the tumor is manipulated.

, Ketoacidosis- hallmark symptoms include acetone breath like nail polish remover
or fruity breath. Also abdominal pain, nausea, vomiting and sob.
When changing from NPH to glargine insulin, how will you adjust the patient's
dose? - Answer: The initial dose of glargine is reduced by 20% to prevent
hypoglycemia.
How does metformin work? - Answer: Decreases hyperglycemia by decreasing
hepatic glucose production called hepatic gluconeogenesis. The average person
with type 2 diabetes has three times the rate of gluconeogenesis, metformin
treatment reduces this by over 1/3rd. The molecular mechanism of metformin
isn't completely understood. In addition to suppressing hepatic glucose
production, metformin increases insulin sensitivity, enhances peripheral glucose
uptake by inducing the phosphorilization of glu4 enhancer factor, decreases
insulin induced suppression of fatty acid oxidation, and decreases absorption of
glucose from the GI tract. Also of note** Metformin helps reduce LDL cholesterol
and triglyceride levels and is not associated with weight gain, in some people it
helps promote weight loss**
What diagnostic testing is required before and throughout therapy with
metformin? - Answer: Metformin is not metabolized, it is cleared from the body
by tubular secretion and is secreted unchanged in the urine. Metformin is
undetectable in blood plasma within 24 hrs of a single oral dose the average
elimination half-life in plasma is 6.2 hrs as it is secreted in the urine you should
check a serum crt to assess renal function.
