administration of the drug, the nurse will assess for:
- CORRECT ANSWER a. increased heart rate.
The nurse is observing the patient's electrocardiographic monitor after insertion of a temporary
pacemaker. Seeing a P-wave after the pacing artifact, the nurse knows that the:

heart rate is 70 beats/min. This phenomenon is reflective of
- CORRECT ANSWER b. pacing artifact; the pacemaker is sensing and capturing.

(MAP) = 95 mm Hg and an intracranial pressure (ICP) = 15 mm Hg.
- CORRECT ANSWER b. 80 mm Hg

for surgery?
- CORRECT ANSWER embolization that can be done to secure the lesion without surgery.
When the condition is more stable, an operation might be considered if needed.
Knowing that a patient has hypoxemia and ischemia in his brain, the nurse anticipates which of
the following?
- CORRECT ANSWER a. Cerebrovascular dilation
The nurse's priority in eye care for the patient in a coma will be:
- CORRECT ANSWER c. keeping the eyes moist to prevent corneal ulceration.

need to have the imbalance of which electrolyte corrected as soon as possible?

Which assessment findings would indicate fluid volume excess?
- CORRECT ANSWER edema, auscultation of a third heart sound, crackles in lungs,
bounding pulses, AMS, olguria, HTN
The report of a renal patient's laboratory results shows that the blood urea nitrogen (BUN)
level is less than 25 mg/dL. To fully understand the patient's renal status, the nurse must
consider this value along with:
CORRECT ANSWER c. creatinine level.
To determine whether edema in a patient's hands is due to circulatory compromise or another
cause, the nurse might:
- CORRECT ANSWER elevate the patient's extremities for 1 hour and observe the degree of
edema still present.
