Correct Answer: A

Rationale: The key to preventing a pandemic influenza is early detection. Detecting influenza cases early allows for timely public health responses to limit the spread of the virus. Early detection helps in implementing measures such as isolation, treatment, and vaccination to prevent the development of a full-blown pandemic. Antibiotics are not effective against influenza viruses, so early antibiotic treatment is not the key to prevention. While vaccination of at-risk populations is important in controlling the spread of influenza, early detection is crucial as it allows for timely implementation of vaccination strategies. Isolation of suspected cases is a containment measure rather than a prevention strategy; the key to prevention lies in early detection to stop the spread before it becomes a pandemic.

Correct Answer: C

Rationale: The correct answer is C. The evaluation stage of the nursing process involves reviewing the assessments, diagnoses, and interventions given to the client and then determining if the client is meeting expected outcomes. In this scenario, the nurse is assessing whether the client is meeting the outcomes set for their care plan and making revisions as needed. Choice A is incorrect as assigning a nursing diagnosis is part of the nursing diagnosis phase, not the evaluation phase. Choice B represents the assessment phase of the nursing process, not the evaluation phase. Choice D involves discussing the client's health history, which is more aligned with the assessment phase rather than the evaluation phase.

Correct Answer: A

Rationale: The presence of small blue-white spots on the oral mucosa, known as Koplik's spots, is characteristic of measles (rubeola) infection. These spots typically appear on the buccal mucosa opposite the second molars, 1-2 days before the rash onset, and last until 2 days after the rash appears. While Koplik's spots are pathognomonic for measles, their absence does not rule out the diagnosis. Therefore, choice A is the correct answer. Choices B, C, and D are incorrect because the rash pattern, presence of low-grade fever, and characteristic appearance of lesions are not specific indicators of measles infection.

Correct Answer: A

Rationale: Abdominal respirations in infants are considered normal due to the underdeveloped intercostal muscles. Infants rely more on their abdominal muscles to facilitate breathing since their intercostal muscles are not fully matured. Therefore, abdominal respirations do not typically require further investigation. Inspiratory grunt, nasal flaring, and cyanosis are findings that warrant additional assessment as they can indicate potential respiratory distress or other underlying health issues in infants. Inspiratory grunt may suggest respiratory distress, nasal flaring can be a sign of increased work of breathing, and cyanosis indicates poor oxygenation, all of which require prompt evaluation and intervention to ensure the infant's well-being.

Correct Answer: A

Rationale: Cultural knowledge involves seeking information and educating oneself about different cultural groups. In this scenario, the nurse is demonstrating cultural knowledge by learning more about deaf culture to improve the care provided to the deaf client. This proactive approach helps in understanding the client's background, beliefs, and communication preferences, leading to better outcomes. 'Cultural noise' and 'Cultural divide' are incorrect as they do not reflect the nurse's positive action of seeking knowledge to enhance care. 'Cultural diversity' is also incorrect as it does not accurately describe the nurse's specific action of acquiring knowledge about a particular culture.
