Now I got it. Thank you for the detailed explanation.

That made complete sense. Thank you so much.

I'm reading in my HESI book that signs of intestinal obstruction include anorexia. How does intestinal obstruction cause anorexia? I cannot animate this in my head. Please help me understand this.

I do not have anything online related to Critical Care. I do have evolve access which includes Evolve case studies, but it does not have Critical Care questions/case studies. It does has some Medical Surgical content, but it does not include topics such as Ventilators, ET tubes, and dysrhythmias. Thanks so much for your response.

Yes I do, but it doesn't has any of the Critical Care contents, like ventilator, ET tube, Dysrhythmia. It does has MedSurge content just not Critical Care content. Thanks so much for responding.

Hi, I'm in need of HESI practice questions for my Critical Care Class. I have search on the internet and even on this site, but I could not find it. I did find HESI practice questions for the HESI exit exam (the test you take so you can graduate), but not for the Critical Care HESI class. I have a HESI book. It comes with a cd with questions but it only has 55 Critical Care questions. Is this any other place where I can find HESI practice questions relating specifically to Critical Care Class? Any help would be much appreciated. Thank you and god bless. NurseForever123

I'm having a hard time understanding the difference between volume and pressure on a ventilator. I know that the "amount" of air that the machine gives to the patient is in mL's, which would mean that it is the volume. Then what/where is the pressure on the vent? I don't understand! Also, I know that minute ventilation is tidal volume times respiratory rate. Is there any significance to this calculation? My med surge book just has the formula, but it does not indicate when this calculation would be Used.

Hypercapnic Respiratory Failure: *Abnormalities of CNS: *Independent of direct brainstem dysfunction, metabolic or structural brain injury resulting in significant depression of consciousness or loss of consciousness may interfere with the patient's ability to manage*secretions or adequately protect his or her airway. What does it mean when the book ways that the patient cannot control their airway? Does it mean that they cannot close their glottis if they need to ?

"The bronchodilator effects of these medications can sometimes cause a worsening of arterial hypoxemia by redistributing the inspired gas to areas of decreased perfusion. Administering the bronchodilator with an mixture oxygen- enriched gas usually alleviates this effect." I don't understand what is meant by "redistributing the inspired gas to areas of decreased perfusion" How does this causes worsening of hypoxemia? Shouldn't it be the opposite?

"Hypoxemia secondary to an intrapulmonary shunt is usually not responsive to high O2 concentrations, and the patient will usually require a positive pressure ventilation." I do not understand this concept. Positive pressure ventilation is either a Cpap or a biPap. A Cpap does not give oxygen, it only give room air. If this is the case, then how does this affect hypoxemia? If this does work, then how come oxygen by face mask does not work? * I do not know what kind of equiptment comes under the category of positive pressure ventilation. Can some body please clarify this for me?

"hypoxemic respiratory failure is commonly defined as a pao2 of 60 mm hg or less when the patient is receiving an inspired o2 concentration of 60% or greater." what does inspired o2 concenteration mean? how does the patient receive this oxygen? is it through the nasal cannula?

Hello, I'm a nursing student in the state of IL, in a BSN program. I have completed Fundaments, Medsurge, and Psych. Unfortunately ever since I started nursing school, I have been having health problems. My condition got so bad that I fell asleep during my final exam and failed OB. I went back to the same college after that and after attending a semester, I started having headaches and jaw pain and found out that my wisdom teeth needs to be removed. I had to take more time off from school to take care of this problem. I do not have health insurance, and I went to the cook county hospital to get my wisdom teeth extraction and they gave me an appointment 8 months from now. The thing is that I'm very worried about failing out of my nursing school. Do you know of any colleges that transfer nursing school classes from a previous school? Also, may I be able to take an LPN route? how long would that take? I hope I dont get sick again. I do not know why God does not want me to go on with my nursing education. It would be a dream job for me.

I'm a BSN student, and I'm ready to apply for my Master's program. But there are so many tracks of MSN that it is getting very confusing. How long does it take to be a Nurse Practitioner? What is the difference between a Nurse Practitioner's education and a general MSN education? For example, my school is offerering a Execute Track MSN program next year. I don't even know what that is. I asked the counselor and he said there's no information on that particular concentration. I surfed the web, but mostly it just said that the Executive Track is mostly for administrative position. But my question is, what exactly do you do as an Administrator? Do you manage the nurses on the floor? Or do you manage financial costs, i.e. what brand of equiptment to use, and things like labor? I'm very confused. I would like to apply for a Master's Program, but I hear different stories from different people. For example, my clinical Preceptor, who is a Nurse Practitioner specializing in Women's Health, told me that the MSN program she was in took 3 years. Another teacher, who is a Family Nurse Practitioner, told me it took her almost 4 years. If the MSN program takes that long, then it just might be worth it to go to Medical School. Please help me understand this! Yes I did surf the web for more information but it only made things complicated! :-(

Hello all. I posted my first thread a couple weeks ago, and I was so pleased with the quick and thoughtful responses that I got from several people. So thank you! I really appreciate people responding to my threads. I'm in the MedSurge semester of the BSN program. We are using Brunner & Suddarth's Textbook of Medical-Surgical Nursing, 11th Edition. We already had our first test on fluids & electrolytes, which was very tough. Our next test is on cardiovascular system/diseases. The test is on about 300 pages of the book. So what my question is: How can I study for this EFFECTIVELY? I'm not asking whether I should use notecards, or type up my paper again and again, or take NCLEX book questions. But rather, how do I recognize important information in the chapter? I want to know what sections I should pick out and concentrate on. For every heart disease in the book, there's sections on pathology, symptoms, risk, medical and nursing management. I don't think most of the information on pathology and symptoms will be on the test, because we've already been tested on that information on pathophysiology. Is that assumption logical? Any advice is appreciated. I'm study atleast 8 hours a day, and NOT procrasting. But I want to make sure I'm studying effectively. There's nothing worse than wasted time.
