NURSING NR 603 WEEK 4 APEA PREDICTOR EXAM | QUESTIONS AND ANSWERS WITH DETAILED EXPLANATIONS 
1.During pregnancy, dyspnea accompanied by increased respiratory rate,
cough, rales, or respiratory distress raises concerns of:
peripartum cardiomyopathy
Explanation:
Dyspnea accompanied by increased respiratory rate, cough, rales, or respiratory distress
raises concerns of possible infection, asthma, pulmonary embolus, or peripartum
cardiomyopathy.
2.The middle section of the thoracic cavity containing the esophagus, trachea,
heart, and great vessels is the:
mediastinum
Explanation:
The middle section of the thoracic cavity containing the esophagus, trachea, heart, and
great vessels is the mediastinum. The right and left pleural cavities, are on either side of
the mediastinum and those contain the lungs. The visceral pleura encloses the lung. The
pericardium surrounds the heart.
3.A patient is unable to identify the smell of an orange. This inability could
reflect an abnormality in cranial nerves:
CN I
Explanation:
Cranial Nerve I is the olfactory nerve responsible for the sense of smell. To test the
sense of smell, the examiner presents the patient with familiar and nonirritating odors.
A person should normally perceive odor on each side and correctly identify the source.
Cranial Nerves II and III assess vision and pupillary reaction. Cranial Nerve VIII tests the
hearing and balance.
4.A transient ischemic attack is:
a transient episode of neurologic dysfunction by focal brain, spinal cord, or retinal
ischemia, without acute infarction
Explanation:
TIA is now defined as “a transient episode of neurological dysfunction caused by focal
brain, spinal cord, or retinal ischemia, without acute infarction.” Ischemic stroke is “an
infarction of central nervous system tissue” that may be symptomatic or silent. The
other terms are not related to the new definitions.
5.The term asteatosis refers to:
skin that is dry, flaky, rough, and often itchy
Explanation:
Physiologic changes of aging include loss of elastic turgor, and wrinkling. Skin that
appears dry, flaky, rough, and itchy is termed asteatosis. Sun exposure can cause
damage to the skin resembling an appearance as weather beaten, thickened,
yellowed, and deeply furrowed.
Seborrheic keratosis appear as raised, yellowish lesions that feel greasy, velvety, or
warty. Painful vesicular lesions in a dermatomal distribution may suggest herpes
zoster.
6.An enlarged liver with a smooth tender edge may suggest:
right-sided heart failure.
Explanation:
An enlarged liver with a smooth, tender edge suggests inflammation, as in hepatitis, or
venous congestion, as in right-sided heart failure. Cirrhosis, hematochromatosis
(increased amount of iron in the blood), and lymphoma produce an enlarged liver with
a firm, nontender edge. An enlarged liver that is firm or hard and has an irregular edge
or surface suggests hepatocellular carcinoma.
7.New onset hypertension with proteinuria or end-organ damage is:
preeclampsia
Explanation:
Chronic hypertension occurs when systolic BP (SBP) >140 mm Hg or diastolic BP (DBP)
>90 mm Hg documented prior to pregnancy, before 20 weeks, or beyond 12 weeks
postpartum.
Gestational hypertension refers to elevated blood pressure detected after 20 weeks
gestation in the absence of proteinuria. Pre-eclampsia occurs in a woman who was
previously normotensive but now has new onset hypertension with either proteinuria
or end-organ damage. Primary hypertension, formerly known as essential
hypertension, is a disorder which is associated with elevated blood pressure and an
unidentifiable cause.
