Question 2 of 5

You are evaluating a 6-mo-old girl with a firm right suprarenal mass. Histologically, there is no bony involvement, 10% bone marrow involvement, subcutaneous nodules involvement, and massive abdominal mass. The N-myc oncogene is not amplified. According to the international neuroblastoma staging system, the infant is stratified as

A. stage I B. stage II A C. stage III D. stage IV S

Correct Answer: D

Rationale: Stage IV S refers to infants <1 year with localized primary tumor, distant metastases limited to liver, skin, or bone marrow (with <10% involvement), and no amplification of N-myc.

Question 3 of 5

The nurse should include which of the following in preprocedure teaching for a patient scheduled for carotid angiography?

A. "You will be put to sleep before the needle Is inserted." B. "The test will take several hours." C. "You may fee! a burning sensation when the dye is injected." D. "There will be no complications."

Correct Answer: C

Rationale: It is important for the nurse to include in preprocedure teaching for a patient scheduled for carotid angiography the information that the patient may feel a burning sensation when the dye is injected. This information helps prepare the patient for a common sensation during the procedure, reducing anxiety and promoting patient understanding and cooperation. Providing this education enhances the patient's overall experience and enables them to better cope with the procedure. The other options are not accurate or complete in providing necessary preprocedure information for the patient.

Question 4 of 5

For a client with polycythemia vera, how can the nurse help decrease the risk for thrombus formation?

A. Teach the client how to perform isometric exercises B. Help the client don thromboembolic stocking or support hose during waking hours C. Advise drinking 3 quarts (L) of fluid per day D. Instruct the client to rest immediately if chest pain develops ïƒ¢ïƒ¢ A1 PASSERS TRAINING, RESEARCH, REVIEW & DEVELOPMENT COMPANY MEDICAL SURGICAL NURSING SET I THE HEMATOLOGIC SYSTEM

Correct Answer: B

Rationale: For a client with polycythemia vera, there is an increased risk for thrombus formation due to the increased viscosity of the blood. Wearing thromboembolic stockings or support hose can help promote circulation, prevent stasis, and reduce the risk of thrombus formation. Compression stockings provide external pressure to the legs, which helps prevent blood from pooling and clotting. This intervention is commonly recommended for patients at risk for thrombus formation to improve blood flow in the lower extremities and reduce the risk of deep vein thrombosis (DVT) and pulmonary embolism.
