Nurse Roberto is aware that a client who has experienced cardiac arrest is MOST at risk for which of the following imbalances?

Correct Answer: D

Rationale: When a client experiences cardiac arrest, their breathing may become insufficient, leading to inadequate elimination of carbon dioxide (CO2) from the body. With reduced CO2 elimination, the level of CO2 in the bloodstream increases, causing respiratory acidosis. This imbalance is characterized by a decrease in blood pH along with an increase in CO2 levels in the blood, resulting in an acidic environment. Respiratory acidosis is the most common imbalance seen in clients who have experienced cardiac arrest, as impaired gas exchange impacts the body's ability to maintain proper acid-base balance.

Correct Answer: A

Rationale: When handling information about families in the community, the nurse should consider the principle of confidentiality as ethical. Confidentiality refers to the obligation of healthcare providers to safeguard the privacy of patient information. By maintaining confidentiality, the nurse upholds trust and respect in the nurse-family relationship. This principle ensures that sensitive information shared by families is kept secure and not disclosed without permission, thus respecting their autonomy and promoting open communication in healthcare settings.

Correct Answer: D

Rationale: The most common symptom of scabies that the family would report to Nurse Emma is itchiness. Scabies is a contagious skin condition caused by the Sarcoptes scabiei mite, which burrows into the skin and lays eggs, leading to intense itching, especially at night. The itching is a result of the body's allergic reaction to the mites and their waste products. While rashes, scaling, and swelling can also occur with scabies, the hallmark and most bothersome symptom experienced by individuals with scabies is the intense itchiness, making it the most common symptom reported by affected individuals or their families during the history-taking process.

Correct Answer: C

Rationale: Assessing the mental status of the patient is the PRIORITY nursing action to determine the patient's ability to concentrate and focus. This assessment includes evaluating the patient's level of alertness, orientation, memory, thought processes, and mood. By observing the patient's mental status, the nurse can gain valuable information about the patient's cognitive function, attention span, and ability to concentrate. This assessment will help guide further interventions and care planning for the patient. Asking for academic performance or conducting paper and pencil tests may be useful tools to assess concentration and focus, but they should come after a comprehensive evaluation of the patient's mental status. Referring the patient to a psychiatrist may be necessary based on the assessment findings, but it should not be the first step in determining the patient's ability to concentrate and focus.

Correct Answer: C

Rationale: In the context of CO-PAR (Community Organizing Participatory Action Research), the most important role of the public health nurse is being an expert. Public health nurses are expected to have specialized knowledge and skills in the field of public health, allowing them to provide evidence-based guidance and interventions to support community health initiatives. As an expert, the public health nurse can assess community needs, develop appropriate interventions, educate community members on health promotion and disease prevention, and evaluate the effectiveness of implemented programs. By utilizing their expertise, public health nurses can effectively contribute to improving the health outcomes and well-being of the community they serve.
