Correct Answer: B

Rationale: In status epilepticus, the most crucial nursing assessment is the level of consciousness. Assessing the client's level of consciousness is vital as prolonged seizures can result in hypoxia, brain damage, and require immediate intervention. Pulse and respirations (choice C) are important assessments, but in status epilepticus, the priority is to monitor the client's neurological status. Checking intravenous fluid infusion (choice A) and extremities for injuries (choice D) are not the primary assessments needed in managing a client experiencing status epilepticus.

Correct Answer: C

Rationale: The correct answer is C, 'Prolonged hypoxemia.' Prolonged hypoxemia is a critical condition that requires specialized pediatric care due to the high risk of cardiac arrest. The other choices, such as congenital cardiac defects, acute febrile illness, and severe multiple trauma, may also require attention, but prolonged hypoxemia poses the highest risk for cardiac arrest and demands specialized expertise in managing pediatric patients with this condition.

Correct Answer: A

Rationale: The correct answer is A: 'Families in their homes, School population, Workers in factories.' As a community health nurse, you are responsible for providing healthcare services and promoting health within the community. This includes visiting families in their homes to assess their health needs, working with the school population to educate them on preventive health measures, and ensuring the health and safety of workers in factories. Choices B, C, and D are incorrect because they do not encompass the full scope of a community health nurse's responsibilities. Choice B does not include workers in factories, Choice C excludes an important population group, and Choice D excludes an essential setting where healthcare services are provided.

Correct Answer: C

Rationale: Immunization programs are the most effective way to prevent the spread of communicable diseases. Vaccinations help build immunity against specific diseases, reducing the likelihood of an outbreak. Regular health check-ups (Choice A) are important for individual health but do not directly prevent the spread of diseases on a community level. Isolation of infected individuals (Choice B) is a containment measure rather than prevention for the entire community. Public health education (Choice D) is valuable in raising awareness but may not be as effective as immunization programs in directly preventing the spread of communicable diseases.

Correct Answer: C

Rationale: The correct answer is C: 'Dyspnea and cough.' Pulmonary embolism often presents with a sudden onset of dyspnea (difficulty breathing) and cough, which are due to the obstruction of blood flow in the pulmonary arteries. Choices A, B, and D are incorrect. Positive Homan's sign is associated with deep vein thrombosis, fever and chills are nonspecific symptoms commonly seen in infective endocarditis, and sensory impairment is not typically indicative of pulmonary embolism.
