A client with left ventricular failure complains of a hacking cough that worsens at night and further complains that shortness of breath sometimes occurs upon wakening. Which intervention should the nurse include in the bedtime preparation?

Rationale:
A. Apply compression stockings: Compression stockings help prevent deep vein thrombosis in clients with limited mobility but do not address spasticity. While important for circulation, they are not effective for controlling involuntary muscle movements.

B. Perform active range of motion exercises: Range of motion exercises maintain joint flexibility and prevent contractures, but they do not sufficiently manage spasticity, which is caused by upper motor neuron injury and requires targeted intervention.

C. Massage the extremities twice a week: Massage may provide temporary relief or comfort but is insufficient to control the frequency or intensity of spastic muscle movements. Relying solely on massage would not adequately manage the condition.

D. Give antispasmodic medications: Antispasmodic agents, such as baclofen or tizanidine, reduce muscle tone and control spasticity by acting on the central nervous system. Administering these medications directly addresses involuntary muscle contractions and improves functional mobility and comfort.

Rationale:
A. Unstable hemodynamics: Performing a thoracentesis in a client with unstable blood pressure or cardiac output increases the risk of circulatory collapse. Fluid removal can further compromise venous return and perfusion, making hemodynamic stability a critical prerequisite for the procedure.

B. Coagulation deficiencies: Clients with coagulopathies, such as low platelet counts or elevated INR, face a high risk of bleeding into the pleural space or chest wall during thoracentesis. Correction of clotting abnormalities is necessary before proceeding to prevent hemothorax or uncontrolled bleeding.

C. Hypertension: Elevated blood pressure alone is not a contraindication for thoracentesis. It may require monitoring and control, but it does not inherently increase procedural risk unless accompanied by other cardiovascular instability.

D. Mechanical ventilation required: Clients on mechanical ventilation can safely undergo thoracentesis when carefully monitored, although it requires expert technique to prevent pneumothorax. The need for mechanical ventilation is not an absolute contraindication.

E. Tracheal deviation: Tracheal deviation is often a sign of mediastinal shift or large pleural effusion, not a reason to avoid thoracentesis. In fact, the procedure may help relieve pressure by removing excess pleural fluid.

F. Infection is incorrect because systemic infection alone is not a strict contraindication; however, infection at the puncture site would be a concern, but this option is too general.
