CCRN-Adult Dumps with Practice Exam Questions Answers

An increase in intracranial pressure (ICP) above 25 mm Hg often results in changes in the waveform morphology observed in the monitoring of intracranial pressure. Specifically, the amplitude of P2 becomes greater than P1, which is indicative of decreased intracranial compliance. This pattern is known as the "pathological waveform," suggesting increased intracranial pressure and decreased ability of the brain to accommodate the pressure changes.

The absence of regulators from O2 tanks is a serious issue that can affect patient care1. The nurse manager is in a position to address this problem effectively by ensuring the availability of necessary equipment2. Therefore, the best action would be to inform the nurse manager of the need for more regulators123. While documenting the issue and reporting to the shift supervisor are important, they do not directly address the problem. Forming a task force could be helpful, but it might take more time to implement solutions23.

Given the symptoms of unilateral facial droop and slurred speech, a stroke is highly suspected. A head and neck CT scan is the most appropriate initial imaging to quickly evaluate for the presence of an ischemic or hemorrhagic stroke, which is critical for determining the appropriate treatment plan. An MRI may provide more detailed information later but is not the initial test of choice in the acute setting. References: = CCRN Exam Handbook, AACN Adult CCRN Certification Review Course

When dealing with a spouse who feels helpless, the most effective nursing intervention is to identify and reinforce their support systems. This helps the spouse feel less isolated and more empowered. Offering solutions to problems, encouraging other family members to make decisions, or providing reassurance that visiting is not necessary do not directly address the spouse's feelings of helplessness and may even contribute to feelings of exclusion or inadequacy.

The patient who has been in the unit for 60 hours and reports agitation, noise disturbances, and an inability to get peace and quiet may be experiencing sleep disturbances. Factors such as the ICU environment, frequent interventions, and the medications being administered (e.g., benzodiazepines, opioids, and bronchodilators) can significantly disrupt sleep patterns, leading to further agitation and delirium. Addressing the patient's sleep hygiene and implementing measures to promote rest can be beneficial.References: = CCRN Exam Handbook, page 52
