How do young children respond to decreased cardiac output? (cardiac 3) A. SV and HR are increased B. SV and HR are decreased C. SV stays the same and HR is increased D. SV is decreased and HR is increased - ANSC The majority of cardiac arrests in kids are due to - ANSRespiratory failure Adrenergic stimulation is one of the compensatory mechanisms used when cardiac output fails. Which of the following is a result of adrenergic stimulation? (cardiac 6) A. Longer diastolic period B. Blocka...

What is vasogenic cerebral edema? - ANSVasogenic cerebral edema is an increase in extracellular fluid caused by a breakdown of the blood-brain barrier with the resultant increase in vascular permeability. This cerebral edema begins locally and becomes more generalized. Common causes are trauma (including surgical trauma), tumors, hemorrhage, and abscesses What ventilator parameter indicates fluid volume excess? - ANSAn A:a gradient greater than 10 mm Hg is a reflection of a diffusion defec...

The nurse is caring for a patient with acute inferior wall MI, post-coronary artery stent deployment, For optimal care of the patient, the nurse should: - ANSContinuously monitor the patient in lead II It is best practice to monitor the patient status post PCI with stent, in the lead that was most abnormal during the acute occlusion. The ECG demonstrates ST elevation in leads II, III and aVF. The nurse needs to monitor the patient closely for which of the following? - ANSComplication likel...

2. A patient presents with a productive cough, hypoxemia, a fever, hypotension, tachycardia, and tachypnea. Hypoxemia was corrected with the administration of oxygen. Which of the following should be done next? A. Administer antibiotics. B. Start a vasopressor. C. Collect a sputum culture. D. Initiate 0.9 normal saline. - ANS(D) Correcting the hypotension (with isotonic fluid resuscitation in order to maintain organ perfusion) is the priority at this time. Antibiotics (choice (A)) will ...

In regards to the Synergy Model for patient care, which of the following refers to an ongoing process in which a nurse generates changes to his or her medical practice via experiential learning and research utilization? A. Clinical inquiry B. Systems thinking C. Response to diversity D. Advocacy/moral agency - ANSA. Clinical Inquiry A patient in the ICU is experiencing acute substance withdrawal. The patient is presenting with symptoms similar to alcohol withdrawal, but it is known that ...

You are monitoring a patient with a pulmonary artery catheter. You are unable to measure the patient's pulmonary artery wedge pressure. To obtain a value that corresponds to the pulmonary artery wedge pressure, you check the: A. Right ventricular pressure B. Pulmonary artery diastolic pressure C. Pulmonary artery mean pressure D. Right atrial pressure - ANSB. Pulmonary artery diastolic pressure When you cannot obtain a pulmonary artery wedge pressure, use the pulmonary artery diastolic ...
