AACN CCRN-Adult - CCRN (Adult) - Direct Care Eligibility Pathway

The primary consideration is to ensure that the family understands the unit's visitation policies. While alternative modalities like therapeutic touch can be beneficial, the nurse must adhere to established policies and explain the rationale to the family. This helps maintain the integrity of unit operations and ensures that all patients receive equitable care. Explaining the policies also provides an opportunity to discuss alternative ways to support the patient within the existing framework.

The patient's tachycardia and hypotension following bowel resection surgery indicate potential severe complications such as hemorrhage or septic shock, which require immediate intervention. If the on-call surgical resident does not provide new orders, the nurse must act promptly to prevent further deterioration by initiating the rapid response team (RRT). The RRT can provide critical interventions and facilitate timely transfer to a higher level of care if needed. References: = CCRN Exam Handbook, AACN Adult CCRN Certification Review Course

A consistent prolongation of the P-R interval beyond 0.20 seconds indicates a first-degree atrioventricular (AV) block. This type of block is characterized by a delay in the conduction of electrical impulses through the AV node, resulting in a prolonged P-R interval. However, every P wave is still followed by a QRS complex, distinguishing it from higher-degree AV blocks where some P waves are not followed by QRS complexes.References: = CCRN Exam Handbook, page 35

Splenomegaly

An x-ray of a person's body Description automatically generated

The patient’s presentation is suggestive of splenic abscess, which is a rare but serious complication of splenomegaly. Splenic abscess is caused by bacterial or fungal infection of the spleen, usually from hematogenous spread or contiguous spread from adjacent organs. The most common symptoms are fever, chills, abdominal pain, and left shoulder pain (Kehr sign). The most significant laboratory finding is positive blood cultures, which indicate systemic infection and sepsis. Other laboratory findings may include leukocytosis, anemia, thrombocytopenia, elevated inflammatory markers, and abnormal liver function tests. However, these are nonspecific and may vary depending on the underlying cause of splenomegaly and the type of microorganism involved.

Glucagon is a hormone that stimulates the liver to release glucose from glycogen stores or from gluconeogenesis. However, when the hepatocytes are damaged by alcoholism or other causes of hepatic failure, glucagon is ineffective because the liver cannot respond to its signal. Glucagon administration is contraindicated for hypoglycemic patients with hepatic failure because it will not raise their blood glucose levels and may worsen their acidosis and electrolyte imbalance123

Anaphylactic shock is characterized by widespread vasodilation due to the release of histamine and other inflammatory mediators. This vasodilation causes a significant drop in systemic vascular resistance and maldistribution of blood volume, leading to hypotension. The explanation addresses the pathophysiological changes that occur during anaphylactic shock. References: AACN Adult CCRN Certification Review Course, AACN CCRN Exam Handbook.

Verified Answer: B. Consult with the pharmacist on the effects of the specific herbs. Herbal therapy is a type of complementary and alternative medicine (CAM) that uses plants or plant extracts to treat various health conditions. Many patients use herbal therapy for various reasons, such as cultural beliefs, personal preferences, or dissatisfaction with conventional medicine. However, herbal therapy is not without risks and challenges, especially in the hospital setting. Some of the potential problems include lack of standardization, quality control, and regulation of herbal products; adverse effects and interactions with other medications; and ethical and legal issues regarding informed consent, documentation, and liability12. Therefore, the nurse’s first action should be to consult with the pharmacist on the effects of the specific herbs that the family wants to administer to the patient. The pharmacist can provide information on the safety, efficacy, dosage, and compatibility of the herbs with the patient’s condition and current medications. The nurse should also inform the patient’s primary provider and obtain an order for the herbs before allowing the patient to take them. The nurse should document the use of herbal therapy in the patient’s medical record and monitor the patient for any adverse effects or changes in response to other treatments. Informing the family that herbal therapy is not appropriate in the hospital is not respectful of the patient’s autonomy and cultural values. Allowing the patient to take the herbs without consulting the pharmacist and obtaining an order is not safe and may violate the hospital’s policies and standards of care.

The appropriate outcomes for a patient with status asthmaticus are normal PaCO2 and increased FEV1. Status asthmaticus is a severe and life-threatening asthma exacerbation that does not respond to conventional treatment. It causes severe bronchoconstriction, air trapping, and mucus plugging, leading to hypoxemia, hypercapnia, and respiratory failure. The goals of treatment are to reverse the airway obstruction, improve gas exchange, and prevent complications. PaCO2 is the partial pressure of carbon dioxide in the blood, which reflects the adequacy of ventilation. FEV1 is the forced expiratory volume in one second, which measures the amount of air that can be forcefully exhaled in the first second of a breath. It reflects the degree of bronchoconstriction and airflow limitation. A patient with status asthmaticus typically has elevated PaCO2 and reduced FEV1 due to poor ventilation and severe obstruction. Therefore, normalizing PaCO2 and increasing FEV1 indicate improvement in the patient’s condition and response to treatment.

Status Asthmaticus: Symptoms, Causes, Diagnosis, and Treatment - Healthline: This article states that “Status asthmaticus is a severe form of asthma with symptoms similar to a typical asthma attack. But for status asthmaticus, symptoms may worsen as the asthma attack continues. Status asthmaticus is an older, less precise term for what’s now more commonly known as acute severe asthma or a severe asthma exacerbation. It refers to an asthma attack that doesn’t improve with traditional treatments, such as inhaled bronchodilators. These attacks can last for several minutes or even hours.”

Status Asthmaticus (Severe Acute Asthma) - WebMD: This article states that “Status asthmaticus is a severe asthma attack that doesn’t get better with your usual treatments. It can be life-threatening and needs urgent medical attention. If you have a bad asthma attack and your rescue inhaler or your nebulizer doesn’t help, you need medical care right away. If an attack comes on quickly and it doesn’t respond to regular treatment, it can lead to status asthmaticus.”

Management of Status Asthmaticus | SpringerLink: This article states that “Status asthmaticus is a life-threatening condition characterized by progressive respiratory failure despite aggressive treatment. It is defined as an acute exacerbation of asthma that remains unresponsive to initial treatment with bronchodilators. Status asthmaticus can vary in severity from mild to fatal. The pathophysiology of status asthmaticus is complex and involves airway inflammation, bronchospasm, airway edema, mucus plugging, and increased airway resistance. The clinical manifestations of status asthmaticus include dyspnea, wheezing, cough, chest tightness, tachypnea, tachycardia, hypoxemia, and hypercapnia. The diagnosis of status asthmaticus is based on history, physical examination, and laboratory tests, such as arterial blood gas analysis, spirometry, and chest radiography. The management of status asthmaticus consists of oxygen therapy, inhaled beta-2 agonists, systemic corticosteroids, and adjunctive therapies, such as anticholinergics, magnesium sulfate, ketamine, and noninvasive or invasive mechanical ventilation. The goals of treatment are to relieve bronchoconstriction, reduce airway inflammation, correct hypoxemia, normalize or reduce carbon dioxide levels, and avoid or treat complications.”

Given the patient's symptoms of hypotension, tachycardia, and intermittent confusion, the safest course of action is to keep the patient in bed to prevent falls and further injury. The patient is at high risk for falls due to their hemodynamic instability and altered mental status. Using a bed pan minimizes the risk of injury compared to allowing the patient to walk, which could lead to falls and worsen their condition.

When seeking to make changes to a documentation screen in the electronic health record (EHR), it is crucial to involve all relevant stakeholders to ensure their buy-in and support. This includes discussing the proposed changes with those who will be directly impacted by it and obtaining their feedback. This collaborative approach can help in identifying potential issues and garnering the necessary support for the proposal, increasing the likelihood of it being accepted by the EHR committee in the future.References: = CCRN Exam Handbook, page 58
