Non-invasive indirect tests
Ureolytic based tests
13C-urea breath technique
UBT as a direct non-invasive test with diagnostic accuracy of >95% (sensitivity >95%, Specificity >95%) is easy to perform and based on urea hydrolysis achieving within gastric mucosal epithelial cells produces ammonia and CO2. In this test, when an individual with H.pylori infection ingests 13C-labled urea, H.pylori as a famous urease enzyme producer breaks down the urea and the labeled CO2 will be monitored within a short time. It takes 2h for collecting the breath samples of patients. Also, a single sample is collectable in 40 min by the help of hyamine as a CO2 trapping agent for exhaling into it. Finally, the percentage of radioactivity of each sample is calculated by a scintillation counter. 13C has a non-radioactive property; so, the test is safe for children and pregnant women. UBT is occurred in different manners such as meal-based 13C UBT, tablet-based 13C UBT and, 14C UBT. Recently, the tablet-based 13C UBT is recommended. Different reports confirm UBT as an accessible, accurate, safe and practical test (45, 48, 58-62).
Serum bicarbonate and Ammonia vapor tests
In addition to UBT, there are other ureolytic techniques including serum bicarbonate and ammonia vapor which have their special applications. In serum bicarbonate test, the measure of serum 13C-carbonate is evaluated. This test is reliable and suitable as post-treatment setting (46).
Ammonia vapor test is used for assessing the level of ammonia gas in the patient breath. This method is absolutely cost effective method (46, 63).

...ophylactic health care is the first choice in the field of infectious diseases. Rapid and accurate diagnostics are absolutely determinant factors to control and treat the infection in early stages.
There are various invasive and non-invasive diagnostic methods for detecting H.pylori infection.
Among non-invasive assays UBT and SAT (FAT) are first-line diagnostic approaches and the serologic tests have the low accuracy. However, the availability, cost and the condition of test performance may differ from place to place. Thus, to improve the diagnostic methods there is no choice rather than combination of two or more techniques with each other.
There are a number of pharmacotherapies which depending on the condition of infection. Preferably, triple therapy is an appropriate choice but in the presence of drug resistant strains, quadruple therapy is recommended.
Ascertaining the adequacy of gaseous exchange is the major purpose of the respiratory assessment. The components of respiratory assessment comprises of rate, rhythm, quality of breathing, degree of effort, cough, skin colour, deformities and mental status (Moore, 2007). RR is a primary indicator among other components that assists health professionals to record the baseline findings of current ventilatory functions and to identify physiological respiratory deterioration. For instance, increased RR (tachypnoea) and tidal volume indicate the body’s attempt to correct hypoxaemia and hypercapnia (Cretikos, Bellomo, Hillman, Chen, Finfer, & Flabouris, 2008). The inclusive use of a respiratory assessment on a patient could lead to numerous potential benefits. Firstly, initial findings of respiratory assessment reveals baseline data of patient’s respiratory functions. Secondly, if the patient is on respiratory medication such as salbutamol and ipratropium bromide, the respiratory assessment enables nurses to measure the effectiveness of medications and patient’s compliance towards those medications (Cretikos, Bellomo, Hillman, Chen, Finfer, & Flabouris, 2008). Thirdly, it facilitates early identification of respiratory complications and it has the potential to reduce the risk of significant clinical

Direct legal issues that result in inadequate infection-control practices, medical costs of healthcare-associated infections and the amount of deaths that have occurred due to these preventable infections are the main targeted issues that will focus on this project. Reporting requirements of HAIs vary from state to state, provider, facility, frequency, and type of infection. Due to this, there is inconsistency in the methods of data collected, risk management, data validation, and the requirement or reporting HAIs. The legal requirements and statutes that mandate disclosure of errors need to be addressed in order to reduce and prevent HAIs. In addition, the discussion of legal duties and responsibilities of the care providers, facilities and patients are discussed.
The ARNP would concentrate her assessment on the respiratory system as Brian presented with a fever and stuffy nose, the condition of cystic fibrosis causes mucus to be thick and sticky which results in narrowing of the airways and hence reduction in air flow thereby affecting oxygenation(Book ref).From the scenario Brian’s height and weight is under the 10th percentile on the growth chart which means that his digestive system has also been affected, hence the physical assessment would be focused on the respiratory, digestive and the immune system.Cystic fibrosis affects the digestive system by blocking the flow of pancreatic enzymes due to obstruction of the thicken pancreatic secretions which blocks the ducts. This results in malabsorption

Factors such as high population density, high speed air travel and antibiotic resistance aid the spread of the disease and contribute to it becoming an outbreak. Epidemiology and other safety measures aid in the protection of the population from outbreaks of disease and alter the susceptibility of the human race to outbreaks of disease.

The signs and symptoms of respiratory distress can be presented clinically as hypoxemia which characterized as a po2 below 50 mmHg and hypercapnia which is an excessive CO2 level in the bloodstream above 45 mmHg. The signs that will manifest on the patient are dyspnea, hyperpnea, intercostal retractions, and cyanosis on digitals. The patient will present anxious and restless and if deteriorate he can be altered. Children can present with the same symptoms along with nasal flaring, retractions, grunting and irritable and later lethargic as he deteriorates his level of consciousness. Nursing interventions include to monitor patient and protect the airway along with preparing for an oral airway insertion or a tracheostomy. Essential interventions may also include raising the head of the bed, suctioning present secretions, monitoring lung sounds for a pneumothorax, monitoring the respiratory effort and depending on the situation we can provide emotional support to decrease the level of anxiety in order to help the patient not work against the o2 delivery method and maximize the
The diagnoses are based on medical tests, a physical examination, and family, medical and diet history, as well as a review of the symptoms. Under family, medical and diet history, the history of the three factors is taken to assist in the diagnosis. The history is analyzed in close association with the symptoms. Symptoms alone cannot be depended on for diagnosis because they might be as a result of other dietary reasons. During physical examinations, a health provider can check for issues like bloating in the abdomen using a stethoscope or tapping on the abdomen to check for pain or tenderness. One of the recommendations that a health provider can offer is the complete elimination of milk and its products from a patient’s dietary composition for some time to observe if the symptoms disappear. In case the symptoms, go away then the lactose intolerance diagnoses can be confirmed. Two main medical tests are used to measure the patient’s lactose digestion ability. One of the tests is the Hydrogen breath test that records hydrogen amounts in the breath of a patient (Ghoshal, 2016). Under normal circumstances, only a little hydrogen amount is detectable. However, in the case of undigested lactose, higher levels of hydrogen are detected. The test involves drinking a beverage containing specified lactose amounts. Then the patient breathes into a container shaped like a balloon that measures the levels of hydrogen. Certain medication, food, as well as smoking might alter the accuracy of the outcomes from this test. The other medical test is the stool acidity test. The test can detect lactic acid, as well as other fatty acids created by undigested

The most effective way to combat pathogenic bacteria which invade the body is the use of antibiotics. Overexposure to antibiotics can easily lead to resistant strains of bacteria. Resistance is dangerous because bacteria can easily spread from person to person. Simple methods for preventing excessive bacterial spread are often overlooked. Not all preventative measures are even adequate. Doctors and patients often use antibiotics unnecessarily or incorrectly, leading to greater resistance. Antibiotics are used heavily in livestock and this excessive antibiotic use can create resistant bacteria and transfer them to humans. In order to reduce resistant bacteria,
Scientifically known as carbonyldiamide or carbonyldiamine, it is a nitrogenous organic compound with the molecular formula of (NH2)2CO as shown in Figure 1.1 below (NCBI, n.d.). While researching on human urine, urea was discovered by H.M. Roulle in 1773 and was first synthesized by a German scientist Friedrich Wohler in 1828 through a mistake when he was actually trying to synthesize ammonium cyanate (Arthur Greenberg, 2007). In the presence of hydrated air, urea has the characteristic smell of ammonia and is odourless in the presence of dry air (NCBI, n.d.). The chemical and physical properties of urea were summarized in Table 1.1 (National Library of Medicine, n.d.)
Avoiding infection or, at least, breaking the chain of transmission is vital in any setting, but more so in healthcare environments where infections and vulnerable hosts are moving under the same roof. What needs to be done, then?
