Correct Answer: B

Rationale: The correct answer is B: Respiratory failure. Patients with COPD have impaired lung function, making them at risk for respiratory failure due to inadequate oxygenation. This can occur due to exacerbation of COPD, infections, or other factors. Monitoring for signs of respiratory distress is crucial. A: Pneumonia - While patients with COPD are at higher risk for pneumonia due to impaired lung function, respiratory failure is a more immediate and critical complication to monitor for in this scenario. C: Hypoglycemia - COPD does not directly increase the risk of hypoglycemia, so monitoring for this complication is not a priority in this case. D: Hypertension - Although some patients with COPD may have hypertension, it is not a common complication directly related to COPD. Monitoring for respiratory failure is more essential in this situation.

Correct Answer: B

Rationale: The correct answer is B: Increased wheezing and shortness of breath. During an asthma exacerbation, bronchial airways become inflamed and narrowed, leading to increased wheezing and shortness of breath. This is a classic sign of worsening asthma. Other choices are incorrect because: A) Decreased work of breathing is not expected in an asthma exacerbation as the patient usually struggles to breathe. C) Improved oxygen saturation is unlikely as airway obstruction can lead to decreased oxygen levels. D) Decreased sputum production is not a typical sign of asthma exacerbation; in fact, increased sputum production may occur due to airway inflammation.

Correct Answer: B

Rationale: The correct answer is B: Percuss the thorax bilaterally, noting any differences in percussion tones. This is the best action because it allows the nurse to assess for potential underlying issues such as pneumothorax or pleural effusion which could be causing the respiratory distress. Percussion can help identify abnormal air or fluid accumulation in the chest. Choice A is incorrect because simply counting respirations does not provide immediate information on the cause of distress. Choice C is incorrect as inspecting for masses and bleeding does not directly address the urgency of the situation. Choice D is incorrect as waiting for a chest x-ray would delay necessary interventions in a critical situation.

Correct Answer: B

Rationale: The correct answer is B because the nurse's response was therapeutic by sharing her own experience to empathize with the patient. This helps establish a connection and validate the patient's feelings. It shows understanding without dismissing the patient's concerns. A is incorrect because the nurse did not provide false reassurance but offered a comforting perspective. C is incorrect as the nurse did not imply that medication was necessary but rather highlighted its availability as an option. D is incorrect since the response did not provide false assurance but rather shared personal experience to offer support.

Correct Answer: A

Rationale: The correct answer is A: Hypertensive crisis. The nurse should be most concerned about this option because the patient has a history of hypertension and is experiencing new onset symptoms such as headaches, nausea, and dizziness, which could indicate a sudden and severe increase in blood pressure. This condition, if left untreated, can lead to serious complications such as stroke or heart attack. Summary: - B: Migraine headache is unlikely as the symptoms described are not typical of a migraine. - C: Benign positional vertigo is unlikely as it does not explain the presence of headaches and nausea. - D: Tension headache is less concerning compared to hypertensive crisis, given the patient's history of hypertension and the severity of symptoms.
