A nurse is planning care for a client diagnosed with systemic scleroderma. The nurse recognizes that an appropriate nursing diagnosis for systemic scleroderma is altered tissue perfusion secondary to which of the following?

A. Chemotherapy is only used for palliation: While chemotherapy can be used for palliative care to relieve symptoms and improve quality of life in advanced cancer, it is also used with curative intent in some cases, especially when cancer is diagnosed early or is responsive to chemotherapy.

B. Chemotherapy cures prostate cancer that has metastasized to the bone: Chemotherapy alone is generally not curative for prostate cancer that has metastasized to the bone. It may help slow disease progression, relieve symptoms, or prolong survival, but it is not typically curative on its own.

C. Chemotherapy is used in conjunction with other treatment modalities in this type of cancer: Chemotherapy is often used in combination with other treatment modalities such as hormone therapy, radiation therapy, or surgery in the management of prostate cancer with bone metastasis. The goal is to target cancer cells using multiple approaches to achieve the best possible outcome for the patient.

D. Chemotherapy makes the body fluid a biohazard: Chemotherapy drugs can be excreted in body fluids such as urine, saliva, and sweat, making them potentially hazardous. However, this statement does not specifically address the role of chemotherapy in the treatment of prostate cancer with bone metastasis.

A. Complete Heart Block: Complete heart block (third-degree AV block) occurs when there is no communication between the atria and ventricles. The atria and ventricles beat independently, resulting in a very slow ventricular rate. This rhythm is characterized by regular P waves that have no relation to the QRS complexes.

B. Sinus Tachycardia: Sinus tachycardia is a rhythm originating from the sinoatrial node with a heart rate typically between 100-150 beats per minute. The rhythm is regular, and the P waves precede each QRS complex consistently.

C. Ventricular Tachycardia: Ventricular tachycardia is a fast heart rhythm that originates from the ventricles. It is characterized by wide and abnormal QRS complexes with a rate usually between 150-250 beats per minute. There may be no visible P waves, and if present, they are not associated with the QRS complexes.

D. Idioventricular Rhythm: Idioventricular rhythm is a slow rhythm originating from the ventricles with a heart rate usually between 20-40 beats per minute. It has wide and abnormal QRS complexes and no visible P waves.
