A nurse is caring for a patient with asthma. The nurse should educate the patient about using a peak flow meter. What is the primary purpose of this device?

Correct Answer: B

Rationale: The correct answer is B: To monitor the amount of airway obstruction. A peak flow meter is used to measure how well the patient can exhale air from the lungs, indicating the degree of airway obstruction in conditions like asthma. By monitoring peak flow readings, the nurse can assess the severity of the patient's asthma and adjust treatment accordingly. Choices A, C, and D are incorrect: A: To measure the amount of oxygen in the blood - This is the function of a pulse oximeter, not a peak flow meter. C: To measure the frequency of inhaler use - This is not the primary purpose of a peak flow meter, which is specifically used to monitor airway obstruction. D: To track blood glucose levels - This is the function of a glucometer, not a peak flow meter used for asthma management.

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. Sodium restriction helps prevent fluid retention and high blood pressure in CKD. 2. Limiting sodium intake is crucial in managing CKD-related complications. 3. Excess sodium can worsen fluid retention and strain the kidneys. 4. Proper understanding of sodium limitation shows patient's grasp of CKD management. Incorrect Choices: B. Increasing fluid intake can worsen fluid retention in CKD patients. C. Excessive protein intake can burden the kidneys in CKD. D. High potassium levels in CKD can lead to dangerous heart rhythm abnormalities.

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: C

Rationale: The correct answer is C: Functional. Functional assessment focuses on roles and relationships of the client by evaluating how well they can perform daily activities and interact with others. This type of assessment provides valuable insights into a client's overall well-being and ability to function independently. Incorrect choices: A: Body systems - This type of assessment focuses on the physical structures and functions of the body, not on the client's roles and relationships. B: Head to toe - This refers to a comprehensive physical examination from head to toe, which does not specifically address the client's roles and relationships. D: Focused - This type of assessment targets a specific issue or concern, but it may not necessarily delve into the client's roles and relationships.

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.
