Correct Answer: A

Rationale: The correct answer is A because a functional assessment primarily focuses on evaluating an individual's health patterns, including their roles and relationships in daily life. This comprehensive approach helps healthcare professionals understand the impact of health on a person's overall well-being and quality of life. Choice B is incorrect because a functional assessment does not specifically cover life-threatening conditions; it is more holistic in nature. Choice C is incorrect as a functional assessment does not prioritize a single health issue but considers multiple aspects of a person's functioning. Choice D is incorrect because although vital sign abnormalities may be part of the assessment, they are not the primary purpose of a functional assessment.

Correct Answer: C

Rationale: The correct answer is C: Critical thinking. Critical thinking involves analyzing information, evaluating options, and making sound decisions. When caring for multiple clients with complex care, critical thinking enables nurses to prioritize tasks, anticipate complications, and adapt care plans accordingly. Diagnostic reasoning (A) is important but focuses on identifying specific health issues. Physical assessment (B) is crucial but only addresses one aspect of care. Nursing care plans (D) are essential tools but rely on critical thinking for effective implementation. In conclusion, critical thinking is the key as it encompasses all aspects of problem-solving in complex care situations.

Correct Answer: A

Rationale: The correct answer is A: Administer albuterol. Albuterol is a bronchodilator that helps open airways, making it effective in treating respiratory distress. It works quickly to relieve symptoms such as shortness of breath and wheezing. Corticosteroids (B) may be used in conjunction with albuterol for severe cases, but albuterol is the immediate intervention. Providing pain relief (C) is not the primary intervention for respiratory distress. Nebulizers (D) are a delivery method for medications like albuterol, but the key intervention is administering the medication itself.

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: Administer bronchodilators. When a client is experiencing respiratory distress, the priority intervention is to open up the airways to improve breathing. Bronchodilators help relax and widen the airways, making it easier for the client to breathe. This intervention addresses the immediate need for improved respiratory function. Administering corticosteroids (choices B and C) may be beneficial in some cases but is not the priority in acute respiratory distress. Monitoring respiratory rate (choice D) is important but does not directly address the underlying issue of airway constriction in respiratory distress.
