Several passengers aboard an airliner suddenly become weak and suffer breathing difficulty. The diagnosis is likely to be

Correct Answer: B

Rationale: In the scenario described, where multiple passengers on an airliner experience sudden weakness and breathing difficulty simultaneously, the most likely cause is chemical exposure. This is because a sudden onset of similar symptoms in a group of individuals suggests a common environmental factor affecting them. Options A, C, and D are less likely as they do not explain a sudden onset of symptoms in multiple individuals simultaneously. Asian flu (Option A) is a viral infection and would not typically result in sudden symptoms in multiple individuals at the same time. Bacterial pneumonia (Option C) is a localized infection and not a probable cause for a sudden onset of symptoms in a group. An allergic reaction (Option D) would usually occur in individuals with specific allergies rather than affecting a group of passengers at the same time.

Correct Answer: A

Rationale: In an emergency situation to assess for airway obstruction, the nurse should prioritize assessing the client's ability to speak. If a client can speak, it indicates that the airway is patent and not completely obstructed, allowing air to pass through the vocal cords for speech production. Choices B, C, and D are not the primary assessments for determining airway obstruction. Assessing the ability to hear is not directly related to an airway obstruction. While oxygen saturation and adventitious breath sounds are important in respiratory assessments, they are not the initial indicators of an airway obstruction. Oxygen saturation reflects the amount of oxygen in the blood, and adventitious breath sounds refer to abnormal lung sounds that may indicate conditions like pneumonia or bronchitis, but they do not specifically confirm airway patency.

Correct Answer: A

Rationale: When assessing a client's mobility status, it is crucial to start by examining their gait. Gait assessment is usually conducted as the client walks into the room. Normal gait is described as smooth, flowing, and rhythmic without the need for assistive devices. Choices B, C, and D are incorrect as they do not represent the standard practice of beginning the assessment of mobility status with gait examination.

Correct Answer: B

Rationale: The correct answer is B: Eclampsia. Eclampsia is a disorder of pregnancy characterized by hypertension, proteinuria, and edema. This condition can cause seizures and/or coma but does not typically present with vaginal bleeding. Choices A, C, and D are abnormal conditions that can cause bleeding, particularly in the third trimester. Placenta previa (choice A) is a condition where the placenta partially or completely covers the cervix, leading to vaginal bleeding. Abruptio placentae (choice C) is the premature separation of the placenta from the uterine wall, causing vaginal bleeding. Uterine rupture (choice D) is a serious obstetrical emergency where the uterus tears during pregnancy or childbirth, resulting in severe bleeding.

Correct Answer: B

Rationale: The correct answer is 'Toddlers.' Toddlers are at the highest risk of unintentional poisoning due to their natural curiosity, explorative behavior, and lack of awareness of potential dangers. Infants are typically closely monitored, teens are more aware of risks, and adults generally have better judgment and understanding of hazardous substances, making them less susceptible to unintentional poisoning. Therefore, toddlers, being inquisitive and unaware of risks, are the most vulnerable group in terms of unintentional poisoning incidents.
