The nurse would monitor what lab value for a patient who has gone for a CT scan with contrast
Serum creatinine level
Based on the knowledge of the primary cause of ESRD, the RN knows to assess what most important indicator?
Serum glucose
Client with ESKD. The nurse is concerned that the client is developing renal osteodystrophy. It is noted that calcium level is 11 mg/dL for the past 3 days and phosphate level is 5.5 mg/dL. The RN anticipates the administration of which medication?
Sevelamer hydrochloride
A nurse completes the Glasgow Coma Scale on a patient with traumatic brain injury (TBI). Her assessment results in a score of 6, which is interpreted as:
Severe TBI A score of 13 to 15 is classified as mild TBI, 9 to 12 is moderate TBI, and 3 to 8 is severe TBI. A score of 3 indicates severe impairment of neurologic function, deep coma, brain death, or pharmacologic inhibition of the neurologic response; a score of 8 or less typically indicates an unconscious patient; a score of 15 indicates a fully alert and oriented patient.
What clinical characteristics are representative of neurogenic shock?
Signs of parasympathetic stimulation—dry, warm skin, hypotension, bradycardia** (other forms of shock are characterized by tachycardia)
A patient in the progressive stage of shock has blood in the NG tube and when connected to suction. You understand that this most likely means that
The patient has developed a stress ulcer that is bleeding
A patient is being seen in a clinic to rule out mitral valve stenosis. Which assessment data would be most significant?
The patient reports shortness of breath when walking.
A patient has an S5 spinal fracture from a fall. What type of assistive device will this patient require?
The patient will be able to ambulate independently. Any injury from S1 - S5, client should be able to move independently without an assist device
In the compensatory stage of shock the nurse understands that which system is stimulated and what occurs
The sympathetic nervous system is stimulated thus stimulating catecholamine release and increasing cardiac contractility
A nurse is preparing a teaching plan regarding biological tissue valve replacement. What is a disadvantage of this type of valve replacement?
The valve has to be replaced frequently.
What does the nurse understand if they notice bubbling in the water seal chamber?
There is an air leak
The nurse is caring for a ventilated client after coronary artery bypass graft surgery. What are the criterions for extubation for the client? Select all that apply.
adequate cough and gag reflexes acceptable arterial blood gas values breathing without assistance of the ventilator
The nurse is discussing basic cardiac hemodynamics and explains preload to the client. What nursing intervention will ****decrease***** preload? application of antiembolic stockings increasing activity administration of a vasodilating drug (as ordered by a health care provider) sustained elevation of the client's legs
administration of a vasodilating drug (as ordered by a health care provider)
Several temporary and permanent sources are available for covering a burn wound. These may be manufactured synthetically, obtained from a biologic source, or a combination of the two. Which graft is described as a biologic source of skin similar to that of the client?
allograft Allograft or homograft is a biologic source of skin similar to that of the client. A xenograft or heterograft is obtained from animals, principally pigs or cows. An autograft uses the client's own skin, transplanted from one part of the body to another.
The most important variable in gas exchange is
alveolar ventilation
What is the drug of choice for a stable client with ventricular tachycardia?
amiodorone
The nurse is providing care to a client with cardiogenic shock requiring a intra-aortic balloon pump (IABP). What is the therapeutic effect of the IABP therapy?
decreased left ventricular workload
Aortic dissection
diagnosis in which the arterial wall splits apart (separates)
Mitral stenosis murmur is a
diastolic rumble heard at apex and/or opening snap
Which is a cerebrovascular manifestation of heart failure?
dizziness
If the aortic valve doesn't close properly during diastole, does blood a) Leak into the right ventricle b) Leak out of the right ventricle c) Leak into the right atrium d) Leak out of the right atrium e) Something else.
e) something else If aortic valve doesnt close, blood leaks back into the LEFT ventricle called aortic regurgitation
A client with a history of mitral stenosis is admitted to the intensive care unit (ICU) with the abrupt onset of atrial fibrillation. The client's heart rate ranges from 120 to 140 bpm. The nurse recognizes that interventions are implemented to prevent the development of
embolic stroke Rationale: mitral stenosis --> increased risk of stroke
ET Tube placement is verified by
end tidal CO2 levels and confirmed via chest x ray
in dilated cardiomyopathy you would expect
enlarged heart on chest x ray systolic murmur at apex dilated heart walls on echocardiogram
