Detailed Explanations
1. During the body's inflammatory process, what causes
edema?
A. Decreased capillary hydrostatic pressure
B. Increased capillary permeability
C. Decreased plasma protein concentration
D. Increased lymphatic drainage
Correct Answer: B. Increased capillary permeability
Rationale: During inflammation, chemical mediators like
histamine cause vasodilation and increase capillary permeability.
This allows fluid, proteins, and cells to move from the blood
vessels into the interstitial space, resulting in edema.
2. A 56-year-old diabetic patient has not taken his insulin in 4
days due to him "feeling well without it." He is admitted to
the ED with an elevated blood sugar. What electrolyte should
be assessed FIRST?
A. Sodium
B. Potassium
,C. Calcium
D. Magnesium
Correct Answer: B. Potassium
Rationale: The patient is at high risk for Diabetic Ketoacidosis
(DKA). In DKA, insulin deficiency leads to the movement of
potassium out of the cells and into the bloodstream
(hyperkalemia), while total body potassium is depleted. Insulin
therapy will drive potassium back into the cells, which can cause a
rapid and life-threatening drop in serum potassium
(hypokalemia). Therefore, potassium levels must be assessed and
monitored closely before and during insulin administration.
3. A 46-year-old woman is considering having another child.
The healthcare providers are explaining to the woman that
children born to women late in life have an increased rate of
having children with which condition?
A. Cystic Fibrosis
B. Down Syndrome
C. Sickle Cell Anemia
D. Hemophilia
Correct Answer: B. Down Syndrome
Rationale: Advanced maternal age (typically defined as over 35)
, is a significant risk factor for chromosomal nondisjunction during
meiosis, which most commonly results in Trisomy 21, also known
as Down 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?
A. Increased resistance to insulin in the cells
B. Decreased production of insulin by the pancreas
C. Increased destruction of insulin by the liver
D. Decreased glucose absorption in the gut
Correct Answer: A. Increased resistance to insulin in the cells
Rationale: Obesity, particularly visceral adiposity, is a primary
driver of insulin resistance. Adipose tissue releases free fatty acids
and inflammatory cytokines that interfere with insulin signaling in
target cells (muscle, liver, fat), leading to decreased glucose
uptake and increased blood glucose levels.
5. When evaluating a patient for hypertensive target organ
damage, the APRN looks for evidence of:
A. Left ventricular hypertrophy
