2024 CCRN TEST BANK EXAMWITH CORRECT ANSWERS
A patient who has been on prolonged bed rest is now allowed to have
physical therapy. Which is an indication of tolerance after 2 days of therapy?
a) SvO2 58%
b) HR 84 (resting HR 68)
c) RR 24
d) SBP 140 mm Hg (resting SBP 118 mm Hg) - CORRECT-ANSWERSCorrect
Answer: HR 84 (resting HR 68)
The following are indications of tolerance to physical therapy: an SBP of 20
mm Hg over or under resting SBP, a RR less than or equal to 20 breaths/min,
a HR less than or equal to 20 beats per minute over resting HR, and a SvO2
greater than or equal to 60%.
When providing care to a patient with status epilepticus, the nurse should
recognize that usually
a) it is a state of continuous seizures lasting more than two minutes.
b) it results from abrupt discontinuation of anti-seizure medications.
c) the patient comes out of the post ictal state between seizures.
d) the cause of death is due to cerebral hemorrhage. - CORRECT-
ANSWERSCorrect Answer: it results from abrupt discontinuation of anti-
seizure medications.
Abrupt discontinuation of anti-seizure medications can cause continuous
seizures or status epilepticus. In status epilepticus, the continuous seizures
last at least five minutes. The patient remains in status epilepticus while in
the post ictal state. The cause of death is usually related to cerebral
hypermetabolism.
REF: Urden LD, et al. 2018.
The nurse is caring for a patient with hypercalcemia. For which imbalance
should the nurse observe?
a) hypoalbuminemia
b) hypokalemia
c) hyperphosphatemia
d) hypermagnesemia - CORRECT-ANSWERSCorrect Answer: hypokalemia
Hypokalemia accompanies hypercalcemia. In rare cases, an increase in
albumin may cause a pseudohypercalcemia. Hypercalcemia leads to urinary
, excretion of magnesium. Hypophosphatemia is associated with
hypercalcemia. REF: Morton PG, Fontaine DK. 2018.
Which is an advantage of pressure support ventilation?
a) decreased muscular endurance
b) decreased inspiratory flow
c) decreased work of breathing
d) decreased FiO2 - CORRECT-ANSWERSCorrect Answer: decreased work of
breathing
Pressure support ventilation assists spontaneous breathing efforts by
delivering a high flow of gas early in inspiration and maintaining that level
through the inspiratory phase. Specific uses of pressure support ventilation
are to promote patient comfort and synchrony with the ventilator, decrease
work of breathing necessary to overcome resistance of the endotracheal
tube, and weaning. The patient's effort determines the rate, inspiratory flow
and tidal volume. As a weaning tool, pressure support ventilation is thought
to increase endurance of respiratory muscles by decreasing physical work
and oxygen demands during spontaneous breathing. Because the level of
pressure support can be gradually decreased, endurance conditioning is
enhanced. Pressure support ventilation does not impact oxygen delivery or
lead to decreased FiO2
Which is an endpoint of volume resuscitation?
a) base deficit 4 mmol/L
b) CVP 3 mm Hg
c) CI 2.4 L/min/m2
d) oxygen consumption 250 mL/min - CORRECT-ANSWERSCorrect Answer:
oxygen consumption 250 mL/min
Oxygen consumption is the amount of oxygen used by the body; normal is
approximately 250 mL/min. CVP below the normal range or at the lower end
of normal and CI below normal range are not therapeutic endpoints for
volume resuscitation. An elevated base deficit is not an indicator of adequate
volume resuscitation. REF: Urden LD, et al. 2018.
Which 12-lead ECG changes should be expected in a patient with ACS
involving the inferior wall?
a) ST segment elevation in leads II, III and all the precordial leads
b) ST segment elevation and deeply inverted T waves in leads II, III and AvF
c) ST segment elevation and deeply inverted T waves in leads V4-V6, I and
aVL
