The nurse obtains a sample of a client's arterial blood gas (ABGs). Which of the following statements is NOT true about ABGs?

Correct Answer: D

Rationale: Arterial blood gases (ABGs) do not directly assess the client's electrolyte and fluid balance. ABGs primarily evaluate the client's acid-base balance and oxygenation status by measuring levels of pH, partial pressure of carbon dioxide (PCO2), and bicarbonate (HCO3) in the arterial blood. While ABGs can provide some information about blood parameters, such as oxygen saturation, they do not comprehensively assess electrolyte levels or fluid balance. To specifically assess electrolytes and fluid balance, additional tests like basic metabolic panels or comprehensive metabolic panels would be required.

Correct Answer: D

Rationale: Knowing the prevalence of diseases provides information on the magnitude of health problems within a community. Prevalence refers to the proportion of individuals in a population who have a particular disease or condition at a specific point in time. By understanding the prevalence rates of different diseases, healthcare providers can better assess the extent of health issues affecting the community. This information is crucial for prioritizing resources and interventions to address the most pressing health concerns effectively. Additionally, prevalence data can guide public health efforts in developing targeted prevention strategies and allocating resources appropriately to improve community health outcomes.

Correct Answer: A

Rationale: Quality improvement measures are most effective when everyone within an organization is involved. This includes not only professional and management staff but also consumers or customers who are directly impacted by the products or services being provided. By involving everyone, a more comprehensive and diverse perspective can be gained, leading to better identification of areas for improvement and more successful implementation of quality improvement initiatives. Additionally, by involving all stakeholders, there is a greater buy-in and commitment to the process, increasing the likelihood of sustainable improvements being made.

Correct Answer: B

Rationale: To keep abreast with the latest trends in peri-operative nursing, Merle should employ a combination of attending training and seminars, performing researches, and pursuing graduate studies. Attending training and seminars will expose Merle to new information, techniques, and best practices in peri-operative nursing. Performing researches will help Merle stay updated with current developments and evidence-based practices in the field. Pursuing graduate studies will provide Merle with advanced knowledge and skills, allowing for a deeper understanding of peri-operative nursing concepts and practices. By incorporating all of these strategies, Merle can ensure that he remains knowledgeable and competent in his role as a peri-operative nurse.

Correct Answer: A

Rationale: The most likely causative agent in this scenario is Plasmodium falciparum, a protozoan parasite that causes malaria. The patient's symptoms of fever, chills, headache, and myalgia align with the typical presentation of malaria. Additionally, the presence of intraerythrocytic ring forms and trophozoites on blood smear examination is characteristic of Plasmodium species, particularly P. falciparum, which causes the most severe form of malaria.

Correct Answer: B

Rationale: In a professional setting like a classroom or a meeting, it is important for the CI (chief instructor) to set the atmosphere by welcoming everyone and discussing the objectives of the ward class. By discussing the objectives, the CI can provide a clear direction for the session and ensure that everyone is on the same page in terms of what needs to be accomplished. This not only helps focus the participants but also creates a sense of purpose and organization, setting a positive tone for the rest of the interaction. Showing a picture of the breast or giving an anecdote about an old man may not be appropriate or relevant in this context. Going ahead with the first part of the lecture without any welcoming or setting the atmosphere may make the participants feel rushed or disconnected from the session's purpose.

Correct Answer: B

Rationale: Opsonization is a process in the immune response where opsonins, which are proteins such as antibodies and complement proteins, bind to pathogens such as bacteria, making them more easily recognized and engulfed by phagocytic cells like macrophages and neutrophils. This coating of pathogens by opsonins enhances the efficiency of phagocytosis, helping in the elimination of pathogens from the body. Opsonins do not facilitate cell lysis, neutralize toxins, or stimulate histamine release; their main function is to tag pathogens for phagocytosis.

Correct Answer: D

Rationale: The most appropriate response is "Many of the health services are given free, but we people pay for them just the same through our taxes." This response acknowledges the fact that public health services are funded by taxpayers, even though they may be perceived as free by the public. It highlights the connection between government funding and the provision of health services, emphasizing that these services are not truly free but are paid for through taxes. It also addresses the misconception that these services are entirely free without any costs involved.

Correct Answer: D

Rationale: Non-maleficence is the ethical principle that emphasizes the obligation to avoid causing harm to patients. In this scenario, the ER nurse clarifies the doctor's prescription to ensure the correct dosage of the pain medication based on the pain scale assessment and the patient's age. By doing so, the nurse is ensuring that the medication is safe and effective for the patient, thus adhering to the principle of non-maleficence. This action demonstrates the nurse's commitment to preventing harm and promoting the well-being of the patient through proper medication management.
