Correct Answer: A

Rationale: Correct Answer: A Rationale: Using the inhaler when feeling an asthma attack coming on allows for prompt relief by opening airways. Waiting for symptoms to worsen (B) can lead to a severe attack. Using the inhaler only when short of breath (C) may delay treatment. Skipping the inhaler when feeling fine (D) can be dangerous if an attack occurs suddenly. Answer A ensures timely intervention for effective asthma management.

Correct Answer: B

Rationale: The correct answer is B: Monitor INR levels. INR (International Normalized Ratio) is a crucial parameter to monitor for clients on anticoagulant therapy, as it measures the effectiveness of the medication in preventing blood clots. By monitoring INR levels, the nurse can ensure the client is within the therapeutic range to prevent both bleeding and clotting complications. Choice A (Monitor platelet count) is incorrect because anticoagulant therapy does not directly affect platelet count, and monitoring platelets is more relevant for clients on antiplatelet therapy. Choice C (Monitor bleeding) is partially correct, but focusing solely on monitoring bleeding may not provide a comprehensive assessment of the client's response to anticoagulant therapy. Choice D (Monitor renal function) is incorrect as anticoagulant therapy primarily affects coagulation factors and not renal function. Renal function monitoring may be necessary for certain medications but is not a primary consideration for anticoagulant therapy.

Correct Answer: B

Rationale: The correct answer is B: Encouraging deep breathing and coughing exercises. This is prioritized in the immediate post-operative period to prevent respiratory complications like atelectasis and pneumonia. Deep breathing helps to expand the lungs and coughing helps clear secretions. Administering pain medication (A) is important but not the top priority. Monitoring for signs of infection (C) is crucial but usually done after ensuring respiratory stability. Providing solid food (D) is contraindicated initially to prevent post-operative complications like ileus.

Correct Answer: D

Rationale: The correct answer is D: Scurvy. Scurvy is caused by a deficiency in vitamin C, which is essential for collagen synthesis. Without enough vitamin C, collagen production is impaired, leading to symptoms like bleeding gums, fatigue, and joint pain. Incorrect Choices: A: Rickets is caused by a deficiency in vitamin D, not vitamin C. B: Marasmus is a severe form of malnutrition due to inadequate intake of calories and protein, not specifically vitamin C. C: Kwashiorkor is a form of severe acute malnutrition typically caused by inadequate protein intake, not vitamin C deficiency. In summary, the correct answer is D (Scurvy) because it directly relates to inadequate intake of vitamin C, while the other choices are associated with different nutrient deficiencies.

Correct Answer: B

Rationale: The correct answer is B: Monitoring serum albumin levels. This is because serum albumin is a protein synthesized by the liver that reflects long-term protein intake and overall nutritional status. Low levels indicate malnutrition or inflammation. Obtaining a dietary history (choice A) is important but may not always reflect the actual nutritional status. Monitoring weight (choice C) is helpful but may not provide a comprehensive view of the client's nutritional status. Providing a meal plan (choice D) is a proactive approach but does not directly assess the client's current nutritional status.
