Correct Answer: C

Rationale: When evaluating the therapeutic effectiveness of digoxin in a client with heart failure, the nurse should expect to find improved respiratory status and increased urinary output. Digoxin helps improve cardiac output and reduces fluid accumulation, leading to improved breathing and increased urinary output. Choices A, B, and D are incorrect because diaphoresis with decreased urinary output, increased heart rate with increased respirations, and decreased chest pain with decreased blood pressure are not indicative of the therapeutic effectiveness of digoxin in heart failure management.

Correct Answer: C

Rationale: The correct answer is C because pain and swelling in the calf can indicate a new or worsening DVT, requiring immediate attention. Bruising on the arms and legs may be a common side effect of anticoagulants but is not as concerning as a potential DVT. Severe headache may indicate other conditions like a migraine or hypertension and is not directly related to DVT. Increased urination is not typically associated with DVT and may point towards other health issues like diabetes or urinary tract infections.

Correct Answer: C

Rationale: A temperature of 99.5 degrees Fahrenheit is slightly elevated but not immediately critical. In a postoperative patient, an elevated temperature could indicate an infection, which requires prompt attention to prevent complications. The respiratory rate, blood pressure, and heart rate within normal ranges are important to monitor but do not indicate an immediate need for intervention as an elevated temperature does.

Correct Answer: D

Rationale: The correct answer is to instruct the client to increase protein intake. This is appropriate because increasing protein intake can help maintain muscle mass and strength in clients with COPD. Option A, 'Drink carbonated beverages,' is incorrect as carbonated beverages can exacerbate COPD symptoms. Option B, 'Decrease fiber intake,' is also incorrect as fiber is important for digestion and should not be decreased unless specifically advised by a healthcare provider. Option C, 'Use bronchodilators after meals,' is incorrect because bronchodilators are typically used before meals to help open the airways for better breathing, not after meals.

Correct Answer: A

Rationale: The correct answer is A because wearing a mask in public can help prevent the spread of TB to others. Choice B is incorrect as taking medication as prescribed helps in treating the infection within the individual but does not directly prevent spreading it to others. Choice C is important for respiratory hygiene but may not be sufficient to prevent transmission. Choice D, isolation until treatment is complete, is crucial for preventing the spread but is not specifically about understanding transmission.
