Correct Answer: C

Rationale: The correct answer is C: Deep vein thrombosis (DVT). After knee replacement surgery, the patient is at a higher risk for developing DVT due to immobility and altered blood flow. Monitoring for signs such as calf pain, swelling, and redness is crucial to prevent complications like pulmonary embolism. Pulmonary embolism (Choice A) is a potential complication of untreated DVT. Gastrointestinal bleeding (Choice B) is not directly related to knee replacement surgery. Hypoglycemia (Choice D) is not a common complication post-knee replacement. Monitoring for DVT is essential in preventing life-threatening complications for the patient.

Correct Answer: C

Rationale: The correct answer is C because spirituality is a personal and intrinsic search for meaning and purpose in life, which is central to the human experience. This definition aligns with the concept of spirituality as a journey of self-discovery and reflection, independent of organized religion or cultural background. Explanation for why other choices are incorrect: A: Worshiping a higher power within an organization implies a religious practice rather than spirituality, which is more individualistic and introspective. B: Attendance at a specific house of worship is a religious practice, not necessarily reflective of spirituality, which can exist outside formal religious institutions. D: While spirituality can be influenced by cultural background, it is not solely tied to it, as it transcends social, ethnic, and historical boundaries.

Correct Answer: C

Rationale: The correct answer is C because stopping the inhaler once feeling better is incorrect. Inhalers are used to manage COPD symptoms long-term, not just when feeling unwell. Step 1: Explain that inhalers are essential for managing COPD and should be used consistently. Step 2: Emphasize that stopping inhaler use prematurely can lead to exacerbation of symptoms and worsening of the condition. Step 3: Reinforce the importance of following the prescribed treatment plan for optimal COPD management. Other choices are incorrect: A: True, avoiding second-hand smoke is crucial for COPD management. B: True, taking medications as prescribed is essential. D: True, breathing exercises can help improve lung function.

Correct Answer: D

Rationale: The correct answer is D because in children, the lung sounds can be different due to their thinner chest walls and more prominent bronchial markings. The louder, longer, and lower-pitched tones heard upon percussion are normal findings in pediatric patients, indicating increased air content in the lungs. Palpating for pain or tenderness (choice A) is not necessary as these findings are expected in children. Asking the child to take shallow breaths and percussing again (choice B) is not needed as the initial findings are normal for the age group. Referring the child immediately (choice C) is unnecessary as these findings are within the normal range for a 4-year-old.

Correct Answer: B

Rationale: The correct answer is B: Providing a source of fast-acting carbohydrate. In hypoglycemia, the priority is to quickly raise the patient's blood sugar levels to prevent potential complications like seizures or loss of consciousness. Fast-acting carbohydrates, such as glucose tablets or juice, can rapidly increase blood sugar levels. Administering insulin (A) would further lower blood sugar levels, worsening the situation. Administering an oral hypoglycemic agent (C) is not appropriate in an acute hypoglycemic episode. Monitoring blood pressure (D) is important but not the priority in this situation.
