CCRN-Adult Exam Dumps : CCRN (Adult) - Direct Care Eligibility Pathway

The spleen plays a crucial role in filtering bacteria and old or damaged blood cells, as well as mounting an immune response. After a splenectomy, the patient is at increased risk for infections, particularly from encapsulated organisms like Streptococcus pneumoniae, Haemophilus influenzae, and Neisseria meningitidis. This heightened susceptibility to infection can lead to sepsis, a life-threatening condition. References: AACN Adult CCRN Certification Review Course, AACN CCRN Exam Handbook.

Sodium nitroprusside (Nipride) is administered after a carotid endarterectomy to decrease mean arterial pressure (MAP) and reduce the risk of hemorrhage at the surgical site. By lowering the blood pressure, it minimizes the chance of bleeding while ensuring adequate cerebral perfusion through careful monitoring.

Nimodipine is a calcium channel blocker that is used to prevent or treat cerebral vasospasm after subarachnoid hemorrhage. It works by relaxing the smooth muscle of the cerebral arteries and improving blood flow to the brain. Nimodipine is the only FDA-approved agent for vasospasm and has been shown to reduce the risk of ischemic complications and improve neurological outcomes12. Lorazepam, propranolol, and pentobarbital are not effective for treating cerebral vasospasm and may have adverse effects on the patient’s blood pressure, heart rate, and level of consciousness.
