While it is important to support family involvement, previous disruptive behavior necessitates setting clear behavioral limits to ensure a safe and therapeutic environment for the patient. Allowing the visit with established guidelines helps balance the need for patient support with maintaining unit order. This approach also respects the patient's rest and recovery needs.

The patient’s findings are consistent with a ruptured diaphragm, which is a tear in the muscle that separates the chest and abdominal cavities. A blunt chest trauma can cause a sudden increase in intra-abdominal pressure, which can rupture the diaphragm and allow abdominal organs to herniate into the thorax. This can cause dyspnea, hypotension, shoulder pain, and bowel sounds over the lower thorax. A ruptured abdominal viscus would cause peritonitis, which would present with abdominal pain, distension, fever, and signs of sepsis. A flail chest would cause paradoxical chest movement, respiratory distress, and cyanosis. A mediastinal shift would cause tracheal deviation, decreased breath sounds, and jugular venous distension.

Dopamine, when administered at a dose of 10 mcg/kg/min, acts primarily as an alpha-adrenergic agonist, leading to vasoconstriction. This results in increased systemic vascular resistance (SVR) and increased mean arterial pressure (MAP), which are desired outcomes in the treatment of septic shock. This effect helps improve perfusion to vital organs and stabilize hemodynamics in patients with septic shock. References: =

The syndrome of inappropriate antidiuretic hormone (SIADH) is characterized by excessive release of antidiuretic hormone (ADH), leading to water retention. This results in fluid intake being greater than urine output (UO), weight gain due to fluid retention, and concentrated urine with increased osmolality and sodium levels. SIADH does not typically present with severe pitting edema or increased serum osmolality and sodium. References: =

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

Verified Answer: C. establish a schedule with the provider. Neurological assessments are important for monitoring the patient’s neurological status and detecting any changes that may indicate a complication or improvement. However, frequent interruptions of sleep can have negative effects on the patient’s health and well-being, such as impaired cognition, mood, immune function, and wound healing. Therefore, the nurse should collaborate with the provider to establish a schedule for neurologic assessments that balances the need for monitoring and the need for rest. This may involve reducing the frequency of assessments during the night, clustering other interventions to minimize disruptions, and using non-invasive methods of assessment when possible. Discontinuing neurologic assessments, encouraging the patient to sleep between assessments, or moving the patient to a quieter part of the unit are not appropriate actions as they do not address the root cause of the problem or ensure adequate monitoring of the patient’s condition.

The first step in developing an orientation plan is to assess the new nurse’s current knowledge and skills. This helps tailor the orientation to address any gaps and build on existing competencies. Understanding the new nurse's background ensures that the training is efficient and effective, focusing on areas that need improvement rather than repeating familiar information.

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.

JVD stands for jugular venous distension, which is a sign of increased pressure in the right atrium and the superior vena cava. Hepatomegaly means enlargement of the liver, which can occur due to congestion of blood in the portal vein and the hepatic vein. Both JVD and hepatomegaly are common symptoms of right-sided heart failure, as they indicate fluid retention and backup in the systemic circulation12. Hypotension and oliguria are not specific to right-sided heart failure, as they can also occur in left-sided heart failure or other conditions that affect the cardiac output and renal perfusion. Hypertension and polyuria are unlikely to be seen in right-sided heart failure, as they indicate increased blood pressure and urine output, which are opposite to the effects of reduced cardiac function and fluid overload. Pulmonary edema and restlessness are more characteristic of left-sided heart failure, as they indicate fluid accumulation and impaired gas exchange in the lungs12.
