The nurse is reviewing Mg levels for a pt. What is the importance of assess this level
for a pt?
a. It may cause ECF overload.
b. Can affect neuromuscular excitability and contractility.
c. It's the most abundant intracellular cation present in the body
d. The pt is at risk for hypotension when the levels decrease.
Give this one a try later!
, b. Can affect neuromuscular excitability and contractility.
Alterations in serum Mg levels profoundly affect neuromuscular excitability
and contractility b/c Mg directly acts on the myoneural junction. A
decrease in blood Mg levels increases the BP. Mg is the second most
abundant intracellular cation (K is the first). The majoring of the body's Mg
is present in the bones.
Normal range for Mg is 1.5 - 2.3 mEq/L.
Which statement by a pt indicates insufficient understanding of the rx'd med
metformin?
a. I should take this med in the AM w/ breakfast.
b. I will need to have my A1c level check in 3 months.
c. I may have diarrhea w/ this med but I should not stop taking it.
d. I will take this med when my blood sugar is > 200 mg/dL.
Give this one a try later!
d. I will take this med when my blood sugar is > 200 mg/dL
Metformin should be taken daily for diabetes control. It's not indicated for
as-needed use. It should be taken w/ breakfast and may initially cause
diarrhea, which will resolve. Drug class = biguanide. It works by reducing
glucose production by the liver and enhancing insulin sensitivity at the
tissue level and improves glucose transport into the cells. It is the most
effective first-line tx for DM type 2. Moderate weight loss is common.
Which persons are most suited for DM screening? Select all that apply.
a. Person w/ HTN
b. Person who's physically inactive
c. Person w/ polycystic ovarian syndrome
,d. Person who delivered a baby weighing 9 lbs
e. Person whose BMI is 25.
Give this one a try later!
A. HTN
b. Physically inactive
c. Polycystic ovarian syndrome
All risk factors of diabetes. In HTN, there's decrease perfusion to tissues,
which may increase the risk of developing DM.
Absence of physical activity results in weight gain d/t lack of utilization of
energy produced by the body.
Hormonal imbalance is seen in pt's w/ polycystic ovarian syndrome, which
may increase the risk for DM.
Which class of drugs used to tx DM may be referred to as "insulin sensitizers?"
a. Sulfonylureas
b. Thiazolidinediones
c. a-glucosidase inhibitors
d. Dipeptidyl peptidase-5 (DPP-4) inhibitors
Give this one a try later!
b. Thiazolidinediones
Thiazolidinediones are a class of drugs used to tx DM. They are often
referred to as "insulin sensitizers." This class of drugs improves insulin
sensitivity, transport, and utilization at target tissues. They are most effective
for pt's who have insulin resistance. Do not cause hypoglycemia. Rarely
used d/t the cardio effects.
Examples include pioglitazone (Actos) and rosiglitazone (Avandia).
Sulfonylureas increases insulin production by the pancreas.
, a-glucosidase inhibitors slow down absorption of the carbohydrate in the
small intestine.
DPP-4 inhibitors enhance the activity of incretins, which stimulate release of
insulin from pancreatic B-cells. Also decreases hepatic glucose production.
A patient with lung cancer is scheduled for surgery. What should the nurse assess to
determine the patient's ability to withstand surgery?
a. Neuro Fx
b. Integumentary Fx
c. Musculoskeletal Fx
d. Cardiopulmonary fx
Give this one a try later!
d. Cardiopulmonary fx
The nurse should perform pulmonary function studies and arterial blood
gases (ABGs) to assess the cardiopulmonary function because these
studies can determine any risks associated with surgery. Neurologic
assessments are performed if brain metastasis is suspected in the patient.
Integumentary and musculoskeletal functions should be assessed in
patients who are suspected to be at risk for distant metastasis.
The nurse is caring for a pt admitted w/ HF. The lab results reveal a serum K level of
2.9 mEq/L. What class of meds should be withheld until consulting the HCP?
a. Antibiotics
b. Loop Diuretics
c. Bronchodilators
d. Antihypertensives
