WGU D027 PRACTICE EXAM 2
QUESTIONS AND ANSWERS WITH
VERIFIED SOLUTIONS 100%
CORRECT!!!
1. What causes edema during the inflammatory response?
✔✔ Increased capillary permeability. This allows plasma to leak into surrounding
tissues, leading to swelling and is the main reason for inflammation-related edema.
2. A 56-year-old diabetic patient has skipped insulin for 4 days and presents to
the emergency department with high blood glucose. Which electrolyte should
be evaluated first?
✔✔ Potassium.
Insulin helps move potassium into cells. Without insulin, potassium remains in the
bloodstream, leading to elevated serum potassium levels.
3. A 46-year-old woman is considering pregnancy. She is informed that having
children later in life is associated with a higher risk of which condition in the
child?
✔✔ Down syndrome. Maternal age over 35 increases the risk of chromosomal
abnormalities, particularly Down syndrome.
Down syndrome
Down syndrome risk increases with Maternal age.
Klinefelter syndrome
,Turner syndrome
4.A patient with several risk factors is concerned about developing type 2 diabetes.
The healthcare professional advises the patient to lose weight, explaining that
obesity is an important risk factor for type 2 diabetes mellitus because it causes
what? - ANSWER✔✔Reduced insulin production by the pancreas
Increased resistance to insulin in the cells
People with type 2 diabetes mellitus suffer from insulin resistance. Obesity causes
this resistance so their cells have difficulty using insulin. Obesity does not lead to
reduced insulin production, obstructed insulin outflow, or stimulation of glucose
production.
Obstructed outflow of insulin from the pancreas
Stimulation of glucose production by the liver
5.When evaluating a patient for hypertensive target organ damage, the APRN
looks for evidence of: - ANSWER✔✔Lipid abnormality
Insulin resistance
Left ventricular hypertrophy
Clotting disorders
, 6.On ultrasound a patient had 4-chamber dilation with an ejection fraction of 15%
and a pleural effusion on chest x-ray. Elevated liver function tests, hypokalemia,
and hypomagnesema are seen on lab results. Blood pressure is 115/60 and heart
rate is 110 bpm with regular rate and rhythm, respiratory rate 30 bpm and O2
saturation is 88% on room air. Initial therapy should include all of the following
except: - ANSWER✔✔Diuretic
ACE Inhibitor
Digoxin
Beta Blocker
7.A patient in the emergency department is suspected of having a myocardial
infarction (MI). The initial cardiac troponin 1 level was negative. What action by
the healthcare professional is best? - ANSWER✔✔Administer thrombolytic
therapy.
Discharge the patient.
Schedule repeat troponin within a few hours.
Several cardiac biomarkers exist including the most specific, cardiac troponin 1
(cTnI), cTnI begins to rise within 2 to 4 hours after cardiac injury, so if the initial
result is normal, the test should be repeated within 6 to 9 hours and again at 12 to
24 hours. It is not known yet if the patient has had an MI so treatment with
