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 D

Explanation

Rationale:
A. Verify the alarm settings on the ventilator: Ensuring alarms are properly set is a routine safety check but does not directly address the client's agitation or risk of self-extubation. It is important but not the priority action in this scenario.

B. Turn on the television: Providing distraction may help reduce mild anxiety but is insufficient for managing significant agitation in a mechanically ventilated client who may become dangerous to themselves if they pull out the endotracheal tube.

C. Obtain a prescription for a vest restraint: Physical restraints should be a last resort after attempting less restrictive methods. Using restraints without addressing the underlying cause of agitation (e.g., discomfort, anxiety, pain) can increase distress and injury risk.

D. Administer a sedative medication: Sedation is appropriate for a mechanically ventilated client who is agitated and at risk for self-extubation. Sedatives help ensure patient comfort, reduce anxiety, and promote ventilator synchrony while protecting the airway.

A. Continuous passive motion device B. Elevated toilet seat C. Trapeze bar D. Compression garment

Correct Answer is B

Explanation

Rationale:
A. Continuous passive motion device: This device is typically used following total knee arthroplasty to maintain joint mobility and prevent stiffness. It is not commonly indicated after total hip arthroplasty, where excessive hip movement is discouraged during early recovery.

B. Elevated toilet seat: An elevated toilet seat helps prevent excessive hip flexion, which reduces the risk of hip dislocation after surgery. It allows the client to sit and stand more safely without bending the hip beyond 90 degrees, which is a critical precaution following hip arthroplasty.

C. Trapeze bar: A trapeze bar may assist some clients in repositioning while in bed, but it is not a standard discharge requirement for hip arthroplasty. Its use is more common in inpatient rehabilitation or in clients with prolonged immobility.

D. Compression garment: While compression stockings may be used to reduce the risk of deep vein thrombosis (DVT), a compression garment is not a standard or essential piece of home equipment following hip replacement surgery unless specifically indicated by the healthcare provider.
