Correct Answer: D

Rationale: The correct answer is 'D.' The client stating 'I may experience some neck swelling' does not indicate a need for further teaching since neck swelling is an expected side effect of radioactive iodine therapy. Choices A and B are correct statements as the client should avoid close contact with pregnant women and children for a few days due to radiation exposure, and dry mouth and taste changes are common side effects. Choice C is redundant with choice D, making D the correct answer.

Correct Answer: C

Rationale: An elevated B-type natriuretic peptide indicates worsening heart failure, which requires immediate attention.

Correct Answer: C

Rationale: A respiratory rate of 26 breaths per minute is an abnormal finding and indicates that the client is experiencing respiratory distress, requiring immediate intervention. This rapid respiratory rate can signify inadequate oxygenation and ventilation. Oxygen saturation of 88% is low but not as immediately concerning as a high respiratory rate, which indicates the body is compensating for respiratory distress. The use of accessory muscles for breathing and a barrel-shaped chest are typical findings in clients with COPD but do not indicate an immediate need for intervention as they are more chronic in nature and may be seen in stable COPD patients.

Correct Answer: C

Rationale: Scheduling an appointment with a podiatrist ensures that the client receives professional foot care.

Correct Answer: D

Rationale: In a client with COPD admitted with pneumonia, a productive cough with green sputum indicates a potential bacterial infection. Green sputum is commonly associated with bacterial pneumonia, which requires immediate intervention with appropriate antibiotics. Monitoring oxygen saturation, respiratory rate, and heart rate are essential in COPD patients, but the presence of green sputum suggests an urgent need for targeted treatment to address the underlying infection. Oxygen saturation of 88% is concerning but may not directly indicate the need for immediate intervention in the absence of other critical symptoms. Respiratory rate of 24 breaths per minute and a heart rate of 90 beats per minute are within normal limits and may not be indicative of an acute issue requiring immediate intervention in this context.
