Correct Answer: A

Rationale: The correct answer is A: Administer oxygen. ARDS is characterized by severe hypoxemia, and oxygen therapy is essential to improve oxygenation. Administering corticosteroids (B) is not recommended as they do not improve outcomes in ARDS. Monitoring serum glucose (C) is unrelated to the treatment of ARDS. Administering pain relief (D) is important for patient comfort but does not address the underlying hypoxemia in ARDS. Oxygen therapy is the primary treatment to support respiratory function and improve oxygen delivery in ARDS.

Correct Answer: D

Rationale: The correct answer is D: Head to toe. This assessment framework allows for modesty by assessing one body part at a time, starting from the head down to the toe. This approach ensures clients, especially teenage girls, feel comfortable and respected during the assessment process. Other choices like A (Body systems) involve assessing multiple body parts simultaneously, potentially compromising modesty. Functional assessment (B) focuses on assessing specific functions rather than individual body parts, which may not address the modesty concern. Focused assessment (C) targets a specific area of concern, which may not provide a comprehensive evaluation while also potentially overlooking modesty concerns.

Correct Answer: A

Rationale: The correct answer is A: Administer albuterol. Albuterol is a bronchodilator that helps open the airways, relieving wheezing in asthma patients. It is the first-line treatment for acute asthma exacerbations. Antihistamines (B) do not treat asthma symptoms. Monitoring for infection (C) is important but not the immediate action for wheezing. Epinephrine (D) is used for severe allergic reactions, not routine asthma management.

Administering corticosteroids (B) is not recommended as they do not improve outcomes in ARDS. Monitoring serum glucose (C) is unrelated to the treatment of ARDS. Administering pain relief (D) is important for patient comfort but does not address the underlying hypoxemia in ARDS. Oxygen therapy is the primary treatment to support respiratory function and improve oxygen delivery in ARDS.

Correct Answer: D

Rationale: The correct answer is D because crossing arms and legs can indicate defensiveness or discomfort, which may suggest the parent is uneasy discussing their son's treatment. This nonverbal cue could signal a need for empathy and sensitivity in communication. Choice A is incorrect as it overlooks the significance of body language. Choice B assumes comfort without considering the context. Choice C assumes tiredness without considering other possibilities. Understanding body language cues can help in building rapport and addressing concerns effectively.
