Final answer:
A home health nurse evaluates caregivers' techniques, ensures all aspects of care are properly managed including checking instruments and labeling specimens, and may provide critical treatments such as dialysis. In research contexts, such as studying disease incidence in a nursing home, statistical hypothesis testing is applied to make conclusions.
Step-by-step explanation:
The home health nurse (hhn) evaluating the caregiver's technique for providing care to a client with a chronic tracheostomy is performing a critical function to ensure that the client receives appropriate care. The nurse reviews procedures and confirms that everything is executed correctly, including checking sponge and instrument counts, making sure specimens are correctly labeled with the patient's name, and noting any equipment issues that need to be addressed. For direct patient care, such as providing dialysis treatments under the direct supervision of a registered nurse, the nurse assesses the patient's history and current condition, responds to needs before and during treatment, monitors the process, and maintains sterility and accuracy of the procedure. In an instance of a research study of an infectious disease within a nursing home, utilizing statistics to conduct a hypothesis test can determine if the local incidence rate is lower than the known percentage. Using a significance level of 0.05, statistical evidence is reviewed to reach a conclusion on the hypothesis.
