A client has a new diagnosis of tuberculosis and has been placed on a multi-medication regimen. Which of the following instructions should the nurse give the client related to ethambutol?

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: Weight gain is not a typical manifestation of tuberculosis. The characteristic symptoms of tuberculosis include a persistent cough, fatigue, and night sweats. Weight loss, not weight gain, is a common symptom associated with tuberculosis due to the impact of the infection on the body's metabolism. Therefore, the healthcare professional should exclude weight gain from the teaching on tuberculosis manifestations.

Correct Answer: B

Rationale: Postmenopausal status is not a significant risk factor for pulmonary embolism. Risk factors for pulmonary embolism include obesity (BMI of 30 or higher), immobility such as having a fractured femur, and conditions like chronic atrial fibrillation that increase the risk of blood clot formation. While postmenopausal status may be associated with other health risks, it is not directly linked to an increased risk of pulmonary embolism.

Correct Answer: A

Rationale: In a client with a pulmonary embolism, bradypnea, which is abnormally slow breathing, is not an expected finding. Pulmonary embolism typically presents with tachypnea (rapid breathing) due to the body's compensatory mechanism to increase oxygen levels. Pleural friction rub, petechiae, and tachycardia are commonly associated with a pulmonary embolism due to the impaired oxygenation and increased workload on the heart. Therefore, the healthcare professional should not expect to find bradypnea during the assessment of a client with a pulmonary embolism.

Correct Answer: C

Rationale: In a client with acute dyspnea, diaphoresis, tachycardia, tachypnea, fever, and hypotension, the priority is to ensure adequate oxygenation. Administering oxygen therapy helps improve oxygenation levels and stabilize the client's condition. This intervention takes precedence over notifying the provider, administering heparin, or obtaining a CT scan, as oxygen therapy addresses the client's immediate need for respiratory support.
