Which approach is the best way to prevent infections when providing care to clients in the home setting?

Correct Answer: A

Rationale: The correct answer is A: Handwashing before and after examination of clients. Handwashing is crucial in preventing the spread of infections as it helps eliminate germs on the hands. Before examining clients, handwashing reduces the risk of transferring pathogens from one client to another. After examination, it helps protect the client and the caregiver from potential infections. Choice B is not the best approach as gloves can sometimes create a false sense of security and may not be as effective as proper handwashing. Choice C may help prevent cross-contamination between client belongings and the nurse's bag but does not directly address infection prevention during care provision. Choice D is specific to certain types of examinations and may not be necessary for all client interactions. Handwashing remains the most effective and universal preventive measure.

Correct Answer: C

Rationale: The correct answer is C: Review the events leading up to each medication administration error. This strategy should be initiated first because it focuses on identifying the root causes of the errors. By reviewing the events, the committee can understand why the errors occurred and implement targeted interventions to prevent them in the future. This proactive approach addresses the underlying issues in the medication administration process, leading to sustainable improvements. Choice A is incorrect because providing an inservice on medication administration to all nurses may not address the specific causes of the errors. Choice B is incorrect as requiring staff nurses to pass an examination may not necessarily prevent errors if the underlying system issues are not addressed. Choice D is also incorrect as developing a quality improvement program for nurses involved in errors is reactive rather than proactive, and does not prevent future errors.

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. A is the correct answer because it addresses the behavior professionally and focuses on unit expectations, not personal attacks. 2. By discussing delegation and task completion expectations, it provides a constructive approach to resolving the conflict. 3. B is incorrect as it focuses on hearsay and does not offer a solution to the problem. 4. C is incorrect as it threatens rather than offering guidance on how to improve. 5. D is incorrect as it uses accusatory language and does not provide a pathway for improvement.

Correct Answer: B

Rationale: The correct answer is B: Income. A continuous variable is one that can take on any value within a certain range. Income can vary continuously and can take on any numerical value within a wide range, making it a prime example of a continuous variable. Gender (A), Religion (C), and Ethnicity (D) are not continuous variables as they are categorical and do not have a continuous range of values. Gender is typically classified as male or female, Religion is categorized into specific belief systems, and Ethnicity is also categorized into distinct groups, making them all discrete variables.

Correct Answer: C

Rationale: The correct answer is C because a confounding variable is a variable that affects both the independent and dependent variables, leading to a false association between them. This can result in misleading conclusions about the relationship between the variables of interest. In contrast, choice A is incorrect because a variable not measured in the study would not impact the relationship between the variables being studied. Choice B is incorrect because a variable manipulated by the researcher would be the independent variable, not a confounding variable. Choice D is incorrect because a variable that is kept constant would not introduce any confounding effects.
