Correct Answer: A

Rationale: The correct answer is A: Administer oxygen. In ARDS, the primary issue is hypoxemia due to impaired gas exchange in the lungs. Administering oxygen helps to increase the oxygen levels in the blood, improving oxygenation to vital organs. Corticosteroids (B) are not indicated as they have not shown consistent benefit in ARDS treatment. Bronchodilators (C) are not effective as ARDS is not primarily a bronchoconstrictive disorder. Applying an ice pack to the chest (D) is not relevant and will not address the underlying hypoxemia. Administering oxygen is the most effective and essential intervention to correct hypoxemia in ARDS.

Correct Answer: B

Rationale: The correct answer is B: Increased shortness of breath. During a COPD exacerbation, airflow limitation worsens, leading to increased difficulty in breathing. This is a common sign due to air trapping and inflammation in the airways. Sudden weight gain (A) is not typically associated with COPD exacerbation. Decreased heart rate (C) is not a common sign and is more likely to occur in other conditions. Increased energy levels (D) are unlikely during a COPD exacerbation as the body is under stress from impaired lung function.

Correct Answer: A

Rationale: The correct answer is A: Perform a lumbar puncture. This is the first action because diagnosing meningitis requires cerebrospinal fluid analysis obtained through a lumbar puncture. It helps identify the specific type of meningitis (bacterial, viral, or fungal) and guides appropriate treatment. Administering pain relief (B) or oxygen (C) may be necessary but not the initial priority. Administering antibiotics (D) should be based on the results of the lumbar puncture to ensure targeted therapy.

Correct Answer: A

Rationale: The correct answer is A: Administer IV fluids. The initial priority in managing sepsis is to restore perfusion and oxygenation by giving IV fluids to support blood pressure and organ perfusion. This helps to improve tissue oxygenation and prevents further organ damage. Administering insulin (choice B) is not the priority in the initial management of sepsis. Monitoring blood pressure (choice C) is important but not the first step in the management of sepsis. Administering insulin is also listed twice and is not relevant to the immediate management of sepsis.

Correct Answer: A

Rationale: The correct answer is A because using the defrost setting on microwave ovens can help safely heat breast milk or formula for the infant without compromising its quality. This method ensures that the milk is heated evenly and prevents hot spots that could burn the baby's mouth. Choice B is incorrect because refrigerating partially used bottles can lead to bacterial growth and contamination. Choice C is incorrect as mixing water and concentrate in different ratios can result in either too diluted or too concentrated formula, which can be harmful to the infant. Choice D is incorrect as adding new formula to partially used bottles can also lead to bacterial growth and spoilage.
