Question The nurse is caring for a client with heart failure. On assessment, the nurse notes that the client is dyspneic and crackles are audible on auscultation. What additional signs would the nurse expect to note in this client if excess fluid volume is present? 1. Weight loss 2. Flat neck an

What is the first intervention for a client experiencing MI? Administer oxygen Administering supplemental oxygen to the client is the first priority of care. The myocardium is deprived of oxygen during an infarction, so additional oxygen is administered to assist in oxygenation and prevent further damage. Morphine and nitro are also used to treat MI, but they’re more commonly administered after the oxygen. An ECG is the most common diagnostic tool used to evaluate MI Question : A 60-year-old comes into the emergency department with crushing substernal chest pain that radiates to the shoulder and left arm. The admitting diagnosis is acute myocardial infarction (MI). Admission prescriptions include oxygen by nasal cannula at 4 L/min, complete blood count (CBC), a chest radiograph, a 12-lead electrocardiogram (ECG), and 2 mg of morphine sulfate given IV. The nurse should first: 1. Administer the morphine. 2. Obtain a 12-lead ECG. 3. Obtain the blood work. 4. Prescr
Breast Examination
The nurse is conducting a class about breast self-examination (BSE). Which of these statements indicates proper BSE technique? a.The best time to perform BSE is in the middle of the menstrual cycle. b.The woman needs to perform BSE only bimonthly unless she has fibrocystic breast tissue. c.The best time to perform a BSE is 4 to 7 days after the first day of the menstrual period. d.If she suspects that she is pregnant, then the woman should not perform a BSE until her baby is born. ANS: The best time to perform BSE is 4 to 7 days after the first day of the menstrual period. The nurse should help each woman establish a regular schedule of self-care. The best time to conduct breast self-examination is right after the menstrual period, or the fourth through seventh day of the menstrual cycle, when the breasts are the smallest and least congested. Advise the pregnant or menopausal woman who is not having menstrual periods to select a familiar date to examine her bre
Breast Feeding and Bottele feeding
During an interview, a patient reveals that she is pregnant. She states that she is not sure whether she will breastfeed her baby and asks for some information about this. Which of these statements by the nurse is accurate with regard to breastfeeding? a."Breastfed babies tend to be more colicky." b."Breastfeeding provides the perfect food and antibodies for your baby." c."Breastfed babies eat more often than infants on formula." d."Breastfeeding is second nature, and every woman can do it." ANS: "Breastfeeding provides the perfect food and antibodies for your baby." Exclusively breastfeeding for 6 months provides the perfect food and antibodies for the baby, decreases the risk of ear infections, promotes bonding, and provides relaxation When a breastfeeding mother is diagnosed with a breast abscess, which of these instructions from the nurse is correct? The mother needs to: a.Continue to nurse on both sides to enc
Biostatistics - Case Fatality Rate
Question : According to 2008 Estimated cancer prevelance and 2011 deaths (in thousands and rounded ) that shown on ( Table below ) , what is the case-fatality rate for pancreatic cancer ? A- 05% B-14 % C-75% D-33% The answer is 30/40 or, 75% . The two pieces of data you need are highlighted green. That’s it!!! The mistake some students make in the forums is that they add the number of fatalities to the total (“All”). For example, the MISTAKE-ANSWER would look like, 30/70. Here, the denominator (70) double counts the 30 fatalities. The number of fatalities, the number males, number of persons over 50, the number of tall people – or, whatever – are ALL subsets of “All.” “All” is the denominator and the ‘thing’ being asked about, like fatalities , in the numerator. BTW, “All” is analogous to “n” (total population) in the many formulae you’ve seen throughout your education.
Descriptive and analytical epidemiology
Descriptive and analytical epidemiology Descriptive epidemiology is used to characterize the distribution of disease within a population. It describes the person, place, and time characteristics of disease occurrence. Analytical epidemiology, on the other hand, is used to test hypotheses to determine whether statistical associations exist between suspected causal factors and disease occurrence. It also is used to test the effectiveness and safety of therapeutic and medical interventions. The tests of analytical epidemiology are carried out through four major types of research study designs: cross-sectional studies, case-control studies , cohort studies, and controlled clinical trials. Cross-sectional studies are used to explore associations of disease with variables of interest. For example, a cross-sectional study designed to investigate whether residential exposure to the radioactive gas radon increases the risk of lung cancer may examine the level of radon gas in
Incidence and prevalence rates
Incidence and prevalence rates The occurrence of disease can be measured by using incidence rates and prevalence rates. The incidence rate measures the occurrence of new cases of a disease in a population over a period of time. The incidence rate is an important measure for evaluating disease-control programs and has implications for the future problems of medical care. For example, the calculation of incidence rates of HIV/ AIDS provides insight into whether the disease is spreading and whether HIV-prevention programs are working. The prevalence rate measures the total number of existing cases of a disease in a population at a given point in time or over a period of time. The prevalence rate is a useful indicator of the burden of a disease on the medical and social systems of a geographic region. It is useful only for diseases of long duration (months or years). For example, within countries, prevalence rates can be used to determine the medical, economic, and social
