NUR 452 Test Questions with 100% Correct
Answers
Which of these clients seen at a health fair will be most at risk for hypertension?
1
23-year-old white man
2
44-year-old white woman
3
50-year-old Mexican-American woman
4
62-year-old African American man
62-year-old African American man
African Americans have the highest risk for hypertension; before the age of 45, men are at
higher risk than women. A 23-year-old white man would be a low risk for hypertension. A
44-year-old white woman would be a somewhat higher risk, but still much less than an
African American man or woman. Mexican-American clients are less likely to seek treatment
for hypertension, but they are not at higher risk than African Americans.
When hypokalemia is suspected, which diagnostic test will the nurse use to confirm the
diagnosis?
1
Complete blood cell count
2
Serum potassium level
,3
X-ray film of long bones
4
Blood Cultures x3
A serum potassium level less than 3.5 mEq/L (3.5 mmol/L) indicates hypokalemia. Complete
blood cell count, x-ray film of long bones, and blood cultures ×3 will have no significance in
the diagnosis of a potassium deficit.
Which of the following would the client with palpitations from premature heartbeats be
taught to avoid?
1
Bananas
2
Tomatoes
3
Energy drinks
4
Green leafy vegetables
Energy drinks should be avoided in the client with palpitations from premature heartbeats
because they contain caffeine and can increase ectopic beats. Bananas and tomatoes are high
in potassium and are not a contraindication for the client with ectopic beats. Dark green leafy
vegetables should be avoided by the client taking warfarin, because the vitamin K content
counteracts the medication's therapeutic blood thinning.
How would the nurse document a drop in blood pressure when a client moves rapidly
from a lying to a standing position?
, 1
Malignant hypotension
2
Orthostatic dehydration
3
Orthostatic hypotension
Orthostatic hypotension specifically refers to an abnormally low blood pressure that occurs
when an individual assumes a standing position. Orthostatic hypotension is also known as
postural hypotension. It may be a result of internal bleeding, fluid depletion, or loss of
neurovascular control preventing vasoconstriction from regulating blood pressure. Malignant
hypotension and orthostatic dehydration are inaccurate terms that are not used. Vasomotor
instability occurs during menopause and results in hot flashes and night sweats.STUDY TIP:
A word of warning: Do not expect to achieve the maximum benefits of this review tool by
cramming a few days before the examination. It doesn't work! Instead, organize planned
study sessions in an environment that you find relaxing, free of stress, and supportive of the
learning process.
Which part of the electrocardiogram (ECG) represents depolarization of the ventricles?
1
P wave
2
T wave
3
PR interval
4
QRS interval
