A nurse is providing care for a client experiencing obstructive shock. Which of the following diagnoses should the nurse expect?

A) "Pentoxifylline can be administered to help the platelets from sticking together and occluding the vessels": Pentoxifylline is a medication used to improve blood flow by decreasing the viscosity of blood. However, it is not typically used to treat mitral valve stenosis. This statement does not accurately reflect treatment options for this condition.

B) "A heparin bolus is administered and followed with a continuous infusion to help keep the blood thinner": Heparin is an anticoagulant used to prevent blood clot formation, but it is not a treatment for mitral valve stenosis itself. While anticoagulants may be used in certain situations with mitral valve stenosis (such as in the setting of atrial fibrillation), they do not directly address the underlying valve narrowing.

C) "A flexible catheter will be inserted into a vessel of the arm, neck, or groin and advanced to the heart to dilate a narrowed or occluded artery": This statement describes a procedure known as percutaneous transluminal mitral valvuloplasty (PTMV), which is a minimally invasive intervention used to treat mitral valve stenosis. During this procedure, a catheter with a deflated balloon on its tip is inserted into a vessel and guided to the heart, where the balloon is inflated to widen the narrowed valve.

D) "A small catheter with a balloon on the end is threaded into a vessel in the groin and advanced to the heart where the balloon will be inflated, and the narrowed valve will be dilated": This statement accurately describes balloon valvuloplasty, which is a common procedure used to treat mitral valve stenosis. By inflating the balloon within the narrowed valve, the procedure aims to widen the valve opening, thus improving blood flow through the heart.

A. Poor functional ability: While poor functional ability may impact the overall prognosis and quality of life for a client with a subarachnoid hemorrhage (SAH), it is not directly associated with a high mortality rate. Functional ability can be improved with rehabilitation and supportive care.

B. Rebleeding of the injury: Rebleeding of the SAH is a significant risk factor associated with a high mortality rate. Rebleeding can lead to increased intracranial pressure, worsening neurological deficits, and even death. Preventing rebleeding is a critical aspect of managing SAH to improve outcomes.

C. Decreased cerebrospinal fluid: Decreased cerebrospinal fluid (CSF) may indicate conditions such as hydrocephalus, which can complicate the management of SAH. However, it is not directly associated with a high mortality rate compared to rebleeding.

D. Use of nimodipine: Nimodipine is a calcium channel blocker commonly used in the management of SAH to prevent cerebral vasospasm, which can lead to ischemia and worsen outcomes. While nimodipine plays a role in improving outcomes by preventing vasospasm, its use is not directly associated with mortality rates.
