Which of the following are symptoms of hypoglycemia?
A - tachycardia and trembling
B - bradycardia and diaphoresis
C - anxiety and flushed, dry skin
D - flushed, dry skin and tachycardia - Correct Answer ✔✔ A - tachycardia and
trembling
When the blood glucose drops, sympathetic stimulation occurs. (symptoms are masked
for a patient who is receiving beta-adrenergic blocker drugs.) Flushed, dru skin is a sign
of hyperglycemia.
Which of the following is TRUE for a patient who has had a right-sided stroke and
develops increased intracranial pressure?
A - pupils will change before level of consciousness does, there will be right-sided
paralysis, eyes will be deviated to the left, and there will be a left pupil change
B - pupils will change before level of consciousness does, there will be left-sided
paralysis, eyes will be deviated to the right, and there will be a right pupil change
C - level of consciousness will change before pupil changes, there will be right-sided
paralysis, eyes will be deviated to the left, and there will be a left pupil change
D - level of consciousness will change before there will be pupil changes, there will be
left-sided paralysis, eyes will be deviated to the right, and there will be a right pupil
change - Correct Answer ✔✔ D - level of consciousness will change before there will be
pupil changes, there will be left-sided paralysis, eyes will be deviated to the right, and
there will be a right pupil change
Higher brain centers (cerebral cortex) are the first to be affected by increased ICP.
Therefore, the level of consciousness is the first sign (except for epidural hematoma).
Pupil changes are ipsilateral (same side as the injury) d/t compression of cranial nerve
III against the transtentorial notch. Motor changes are contralateral (oppo side of the
injury) d/t motor fiber crossing in the brain stem.
A patient status-post head trauma has an IP of 32 mmHG. Which of the following
interventions is contraindicated for this patient?
A - provide enteral feeding via nasal tube
B - elevate HOB 30-45 degrees
C - maintain MAP 50-60 mmHg
D - avoid hypotonic IV solutions - Correct Answer ✔✔ C - maintain MAP 50-60 mmHg
, Patient has an elevated ICP and requires MAP > 50-60 mmHg in order to maintain
cerebral perfusion pressure and prevent brain ischemia. The remaining interventions
are INDICATED for a patient with elevated ICP.
Which of the following is associated with mitral regurgitation?
A - systolic murmur, sinus bradycardia
B - diastolic murmur, heart failure
C - systolic murmur, inferior wall MI
D - diastolic murmur, complete heart block - Correct Answer ✔✔ C - systolic murmur,
inferior wall MI
Inferior wall MI may result in ischemia and dysfunction (regurgitation) of the mitral valve.
The mitral valve is closed during systole (left ventricular ejection). A murmur is produced
when the mitral valve is not fully closed during systole.
A nurse knows that research supports a patient having unrestricted access to his or her
designated support person (according to the patient's wishes). However, the nurse's
unit restricts all patient visitors to set times. The nurse's best response would be to:
A - gather facts and propose a policy change to the manager of the unit
B - tell patient's/visitors that the unit's policy is outdated but there is nothing that can be
done about it
C - continue to follow the unit policy
D - complain to colleagues about the unit's outdated policy - Correct Answer ✔✔ A -
gather facts and propose a policy change to the manager of the unit
AACN Synergy Model supports patient advocacy. Unrestricted access to a designated
support person is an evidence-based practice that is included in the "Family Presence:
Visitation in the Adult ICU" AACN Practice Alert. Choice A is an effective strategy for
change.
Nitrate therapy is indicated for the treatment of unstable angina and acute heart failure
because it:
A - decreases preload and increases myocardial 02 demand
B - increases preload and increases myocardial 02 demand
C - increases preload and decreases myocardial 02 demand
D - decreases preload and decreases myocardial O2 demand - Correct Answer ✔✔ D -
decreased preload and decreases myocardial O2 demand
Nitrates cause venodilation, which results in a decrease in venous return to the heart
(left ventricular preload reduction). The decrease in preload decreases the work of the
left ventricle and the myocardial oxygen demand.
