Correct Answer: C

Rationale: Bradycardia, which is a slow heart rate, is not typically associated with a pneumothorax. In a pneumothorax, the presence of air in the pleural space can lead to lung collapse, causing symptoms such as tachypnea (rapid breathing), deviation of the trachea, and pleuritic pain. Monitoring for bradycardia may not be as relevant in this context as it is not a typical indicator of a pneumothorax.

Correct Answer: A

Rationale: Vecuronium is a neuromuscular blocking agent used for muscle relaxation during mechanical ventilation. When administering vecuronium, it is common to also give an opioid analgesic, such as fentanyl, to manage pain and ensure the patient's comfort. Fentanyl is often used in combination with neuromuscular blocking agents to provide balanced anesthesia, making it the appropriate medication to anticipate administering in this scenario.

Correct Answer: A

Rationale: Thrombolytic therapy involves the use of medications to dissolve blood clots. Hip arthroplasty (joint replacement surgery) performed recently is a contraindication to thrombolytic therapy due to the risk of bleeding. Elevated sedimentation rate, exercise-induced asthma, and elevated platelet count are not contraindications to thrombolytic therapy.

Correct Answer: C

Rationale: Ethambutol is associated with potential vision changes, including optic neuritis. Patients should be instructed to report any visual disturbances immediately to prevent permanent vision loss. Monitoring for changes in vision is crucial to detect any adverse effects early on and prevent serious complications.

Correct Answer: B

Rationale: The correct statement indicating understanding of tuberculosis medication regimen is 'I will wash my hands each time I cough.' This statement shows knowledge of infection control practices to prevent the spread of tuberculosis. Washing hands after coughing helps in reducing the transmission of the disease to others. The other options are incorrect. Option A is incorrect as each medication in the regimen has a specific role, and substituting one for another can compromise the effectiveness of treatment. Option C is incorrect as obtaining sputum specimens is essential for monitoring treatment response. Option D is incorrect as the client should still adhere to infection control measures and avoid exposing others to tuberculosis.
