護理師照護疑似嗜鉻細胞瘤的病人。為了預防高血壓危象，哪項行動是禁忌？
A nurse is caring for a client with a suspected pheochromocytoma. Which action is contraindicated to prevent a hypertensive crisis?
- AAdministering alpha-adrenergic blockers施用甲型腎上腺素受體阻斷劑
- BEncouraging a high-calorie diet鼓勵攝取高熱量飲食
- CPalpating the abdomen✓ 正解觸診腹部
- DMonitoring blood pressure frequently頻繁監測血壓
嗜鉻細胞瘤 (pheochromocytoma) 是一種罕見的腎上腺髓質腫瘤，會不規則地分泌過量的兒茶酚胺 (catecholamines)，如腎上腺素 (epinephrine) 和正腎上腺素 (norepinephrine)。這些激素會導致血壓急劇升高，引起陣發性高血壓危象 (hypertensive crisis)，嚴重時可能危及生命。 在照護疑似嗜鉻細胞瘤的病人時，護理師的首要目標是避免任何可能刺激腫瘤釋放兒茶酚胺的行為，以預防高血壓危象的發生。觸診腹部 (palpating the abdomen) 會直接刺激腎上腺區域的腫瘤，導致大量兒茶酚胺突然釋放，從而引發嚴重且致命的高血壓危象。因此，觸診腹部是絕對禁忌的行動，護理師必須避免。 其他選項的行動則是必要的監測或治療措施，有助於管理病情。
Pheochromocytoma is a rare adrenal medullary tumor that secretes excess catecholamines (epinephrine and norepinephrine) irregularly. These hormones cause abrupt severe BP elevation and paroxysmal hypertensive crisis, which can be life-threatening. In caring for a client with suspected pheochromocytoma, the priority is to avoid any action that could stimulate tumor release of catecholamines. Palpating the abdomen directly stimulates the adrenal mass and can trigger sudden, massive catecholamine release, producing a severe and potentially fatal hypertensive crisis. Therefore, abdominal palpation is absolutely contraindicated. The other options are appropriate monitoring or treatment measures.
