NRSG 3100 Exam 2 MEDS QUESTIONS WITH
COMPLETE SOLUTIONS
A deficiency in ADH results in __________. Correct Answer
Diabetes insipidus
Acute adrenal insufficiency usually occurs with abrupt
withdrawal of: Correct Answer Long-term corticosteroid
therapy
Adrenergic agonists have a positive inotropic effect. What does
this mean? Correct Answer Increases the HR and the force of
contraction to increase cardiac output (CO)
Advanced or decompensated heart failure may require
__________ to increase myocardial contractility, without
increasing oxygen demands on the heart and possibly worsening
HF. Correct Answer Positive inotropic drugs
Beta1 activation results in: (3) Correct Answer Increased HR,
increased force of contraction, and increased velocity of impulse
conduction across myocardium
Certain physiologic response are common to all types of shock.
What are they? Correct Answer Hypoperfusion, decreased
oxygenation
D50W is indicated for: Correct Answer The emergency
treatment of insulin hypoglycemia to restore blood glucose
levels
,Glycogen is stored and broken down into glucose by the
__________. Correct Answer Liver
Heart failure is accelerated by conditions such as: (3) Correct
Answer CAD, MI, HTN
HHS is characterized by: (4) Correct Answer Hyperglycemia
(>600 mg/dL), hyperosmolarity (>310 mOsm/L) with
dehydration, CNS dysfunction, and absence of ketoacidosis
How does potassium iodide protect the thyroid in instances of
radiation exposure secondary to nuclear accident? Correct
Answer Potassium iodide is taken up by the thyroid gland,
blocking the uptake of radioactive iodide
How is phenylephrine different compared to epinephrine? (3)
Correct Answer Compared to epinephrine is has a long
duration of action, less significant cardiac effects, and may
cause bradycardia
How should D50W be administered? Correct Answer IV in a
large vein
Hyperosmolar Hyperglycemic State (HHS) is generally seen in:
(4) Correct Answer Generally seen in type 2 DM; often
elderly, obese, with comorbidities
In DM, excess glucose molecules increase osmotic pressure,
leading to: Correct Answer Polyuria and polydipsia
, In DM, insufficient nutrient stores become depleted, triggering
__________. Correct Answer Polyphagia
In what group does thyroid crisis occur most often in? Correct
Answer Young women with undiagnosed/untreated
hyperthyroidism
Insulin and glucagon are both released by the __________.
Correct Answer Pancreas
IV administration of nonselective adrenergic agonists initiates
widespread __________, causing an intense "fight or flight"
response. Correct Answer Activation of the sympathetic
nervous system
Phenylephrine should not be administered within 21 days of an
MAOI. Why? Correct Answer It may cause a hypertensive
crisis
Selective alpha adrenergic agonists are used to treat: Correct
Answer Hypotension associated with shock
Serum glucose is maintained by what hormones? Correct
Answer Insulin and glucagon
Some drugs, such as __________, mask sympathetic symptoms
of hypoglycemia, delaying awareness and treatment. Correct
Answer Beta-adrenergic blockers
