Test Bank for Pediatric Nursing : The Critical Components of Nursing Care, 2nd Edition, Kathryn Rudd, Diane Kocisko

Chapter 14: Nervous System Alterations Test Bank MULTIPLE CHOICE 1. The nurse admits a patient to the critical care unit following a motorcycle crash. Assessment findings by the nurse include blood pressure 100/50 mm Hg, heart rate 58 beats/min, respiratory rate 30 breaths/min, and temperature of 100.5°. The patient is lethargic, responds to voice but falls asleep readily when not stimulated. Which nursing action is most important to include in this patient’s plan of care? a. Frequent neurological assessments b. Side to side position changes c. Range of motion to extremities d. Frequent oropharyngeal suctioning ANS: A Nurses complete neurological assessments based on ordered frequency and the severity of the patient’s condition. The newly admitted patient has an altered neurological status so frequent neurological assessments are most important to include in the patient’s plan of care. Side to side position changes, range of motion exercises, and frequent oral suctioning are nursing actions that may need to be a part of the patient’s plan of care but in the setting of increased intracranial pressure should not be regularly performed unless indicated.

Her blood pressure is 144/90 mm Hg, and her mean arterial pressure (MAP) is 108 mm Hg. What is the cerebral perfusion pressure (CPP)? a. 54 mm Hg b. 72 mm Hg c. 90 mm Hg d. 126 mm Hg ANS: C CPP = MAP – ICP. In this case, CPP = 108 mm Hg – 18 mm Hg = 90 mm Hg. All other calculated responses are incorrect. DIF: Cognitive Level: Comprehension REF: pp. 360-361 OBJ: Complete an assessment on a critically ill patient with nervous system injury.

While caring for a patient with a traumatic brain injury, the nurse assesses an ICP of 20 mm Hg and a CPP of 85 mm Hg. What is the best interpretation by the nurse? a. Both pressures are high. b. Both pressures are low. c. ICP is high; CPP is normal. d. ICP is high; CPP is low. ANS: C The ICP is above the normal level of 15 mm Hg. The CPP is within the normal range. All other listed responses are incorrect. DIF: Cognitive Level: Comprehension REF: p. 361 OBJ: Complete an assessment on a critically ill patient with nervous system injury.

The nurse needs to perform an hourly neurological assessment, suction the endotracheal tube, perform oral hygiene care, and reposition the patient to the left side. What is the best action by the nurse? a. Hyperoxygenate during endotracheal suctioning. b. Elevate the patient’s head of the bed 30 degrees. c. Apply bilateral heel protectors after repositioning. d. Provide rest periods between nursing interventions. ANS: D Sustained increases in ICP lasting longer than 5 minutes should be avoided. This is accomplished by spacing nursing care activities to allow for rest between activities. All other nursing actions are a part of the patient’s plan of care; however, spacing out interventions is the priority.

While caring for a patient with a basilar skull fracture, the nurse assesses clear drainage from the patient’s left naris. What is the best nursing action? a. Have the patient blow the nose until clear. b. Insert bilateral cotton nasal packing. c. Place a nasal drip pad under the nose. d. Suction the left nares until the drainage clears. ANS: C In the presence of suspected cerebrospinal fluid leak, drainage should be unobstructed and free flowing. Small bandages may be applied to allow for fluid collection and assessment. Patients should be instructed not to blow their nose because that action may further aggravate the dural tear. Suction catheters should be inserted through the mouth rather than the nose to avoid penetrating the brain due to the dural tear.

The patient was unconscious at the scene briefly but is now conscious upon arrival at the emergency department (ED) with a GCS score of 15. One hour later, the nurse assesses a GCS score of 3. What is the priority nursing action? a. Stimulate the patient hourly.
