A nurse is assessing a client who has tuberculosis and recently began taking ethambutol. The nurse should identify which of the following findings as an adverse effect of this medication?

Blurred vision

Tinnitus

Peripheral edema

Bradycardia

Answer and Explanation

The Correct Answer is A

Rationale:
A. Blurred vision: Ethambutol is known to cause optic neuritis, which can lead to blurred vision, decreased visual acuity, and impaired red-green color discrimination. Clients on ethambutol should be monitored for changes in vision and advised to report any visual disturbances immediately.

B. Tinnitus: Tinnitus is not a typical adverse effect of ethambutol. It is more commonly associated with other anti-tuberculosis drugs such as streptomycin, which can cause ototoxicity, especially affecting the auditory and vestibular systems.

C. Peripheral edema: Peripheral edema is not commonly linked to ethambutol use. It may occur with certain cardiovascular medications or conditions but is not an expected side effect of this antitubercular drug.

D. Bradycardia: Bradycardia is not a recognized adverse effect of ethambutol. This medication primarily affects the eyes rather than the cardiovascular system. Monitoring for vision changes is a higher priority when assessing for side effects.

Correct Answer is ["A","B","C","D","E","F","G"]

Explanation

Rationale:

Client reports chest pain as 4 on a scale of 0 to 10: Chest pain, even when moderate, is a red flag symptom for possible myocardial ischemia, especially in a high-risk client. Prompt evaluation is essential to rule out unstable angina or early myocardial infarction.
Client reports fatigue over the last several months: Chronic fatigue may be an early and often overlooked symptom of cardiovascular disease in women. In the context of other cardiac risk factors, this requires further cardiac workup.
Client reports intermittent epigastric discomfort upon exertion: Epigastric discomfort on exertion may reflect angina equivalents, especially in women and diabetic patients. It may indicate myocardial ischemia and requires immediate attention.
Client reports experiencing occasional nausea and heart palpitations: Nausea and palpitations may be atypical symptoms of cardiac ischemia or arrhythmias. These signs are concerning when paired with chest discomfort and cardiovascular history.
History of smoking 1 pack per day for the past 30 years: Smoking is a major modifiable risk factor for coronary artery disease. Long-term tobacco use contributes to endothelial dysfunction and increases the risk of acute cardiac events.
Past medical history of type 2 diabetes mellitus, systemic lupus erythematosus, hypertension, and hyperlipidemia: This cluster of comorbidities places the client at extremely high risk for cardiovascular complications. Each condition independently contributes to atherosclerosis and cardiac event risk.
Father died at age 50 with coronary artery disease:A strong family history of premature CAD significantly elevates this client’s cardiac risk. It intensifies the concern for hereditary predisposition to cardiovascular events.

A. Remain 0.3 m (1 ft) away from children. B. Limit the time spent around women who are pregnant to 10 min daily. C. Use disposable utensils for meals. D. Use an absorbent pad if incontinent.

Correct Answer is C

Explanation

Rationale:
A. Remain 0.3 m (1 ft) away from children: Clients receiving radioactive iodine therapy are advised to maintain a greater distance—typically 1 to 2 meters (3 to 6 feet)—from children and pregnant women for several days to limit radiation exposure.

B. Limit the time spent around women who are pregnant to 10 min daily: Clients should actually avoid close contact with pregnant women entirely for several days post-treatment, not merely limit contact time, to prevent radiation exposure to the fetus.

C. Use disposable utensils for meals: After radioactive iodine therapy, clients may excrete small amounts of radiation in saliva and other bodily fluids. Using disposable utensils helps prevent contaminating shared household items and protects others from exposure.

D. Use an absorbent pad if incontinent: While using precautions to manage bodily fluids is important, this instruction is relevant only if the client is incontinent. It is not a universal teaching point for all clients undergoing radioactive iodine therapy.
