RN exams medical-surgical practice questions set 4

Correct answer:

The correct answer is C because the patient experiencing a loss of consciousness immediately following the injury, regaining consciousness quickly, and then losing consciousness again is indicative of an epidural hematoma. This pattern is known as the "lucid interval," where the initial impact causes bleeding between the skull and dura mater, leading to a temporary improvement in symptoms before the hematoma expands, causing increased intracranial pressure and loss of consciousness. Choice A (Goose egg' noted on patient's head) is not specific to epidural hematoma and can occur in various head injuries. Choice B (The patient is unconscious when you arrive on the scene and remains that way throughout transport) is more indicative of a severe traumatic brain injury with continuous loss of consciousness rather than the characteristic pattern of an epidural hematoma. Choice D (Sudden, severe headache) is more commonly associated with subarachnoid hemorrhage or traumatic brain injury but not specifically with epidural hematoma.

Correct answer:

The most critical action to prioritize for ensuring patient safety during a cardiopulmonary exercise stress test is to monitor the patient's electrocardiogram (ECG) rhythm continuously during the test (Option B). This monitoring allows the healthcare team to promptly detect any abnormal heart rhythms or signs of cardiac distress, enabling timely intervention if necessary. Continuous ECG monitoring is essential during exercise testing as it helps in assessing the heart's response to physical activity and identifying any potential cardiac abnormalities or complications that may arise during the test. By closely monitoring the ECG rhythm, the nurse can ensure the patient's safety and well-being throughout the procedure. Administering a beta-blocker medication before the test (Option A) may be indicated in some cases but is not as crucial as continuous ECG monitoring during the test. Encouraging the patient to consume a heavy meal before the test (Option C) is contraindicated as it can interfere with the accuracy of the results

Correct answer:

When assessing and managing distress in a patient with advanced dementia who is no longer able to communicate verbally, the palliative nurse should consider exploring non-verbal cues and behaviors to identify the underlying causes of distress. Since the patient cannot communicate through words, it is essential to pay close attention to their non-verbal cues such as facial expressions, body language, and changes in behavior. Distress in dementia patients can be caused by a variety of factors including physical discomfort, unmet needs, environmental stressors, emotional distress, or even medication side effects. By carefully observing and interpreting non-verbal cues, the nurse can gain insight into what might be causing the patient's distress and tailor interventions accordingly. Simply focusing on physical comfort measures may not address the root cause of the distress, and administering sedative medications without understanding the underlying cause is not considered best practice in palliative care for dementia patients.

Correct answer:

Epidermal layers have distinct roles and compositions. The stratum germinativum is the basal layer where cell division occurs, producing cells that eventually keratinize, but it is not primarily associated with keratin itself. The stratum corneum, the outermost layer, is packed with keratin, not melanocytes, which are found in the stratum germinativum and produce melanin. The stratum granulosum is where keratinization begins, with cells accumulating keratin as they die and move upward, making it a fitting match for keratin. The stratum lucidum, present only in thick skin, consists of dead, keratinized cells but lacks blood vessels, which are exclusive to the dermis. The correct pairing hinges on the layer most directly tied to keratin production and accumulation. The stratum granulosum's role in this process forming keratohyalin granules and initiating the transition to the stratum corneum makes it the strongest match, aligning with histological descriptions of epidermal differentiation and keratin's protective function.

Correct answer:

In a situation where a patient with terminal cancer is experiencing severe pain despite receiving analgesics, consulting with a pain management specialist is the most appropriate intervention. Pain management specialists have expertise in managing complex pain situations, especially in cases of terminal illness where pain control is crucial for improving quality of life. The specialist can review the current pain management plan, suggest alternative or adjunct therapies, adjust medication dosages, or explore different types of analgesics to optimize pain relief for the patient. Collaborating with a pain management specialist can help ensure the patient receives the most effective and personalized pain management approach tailored to their specific needs. Increasing the dose of analgesics, administering a different type of analgesic, or recommending non-pharmacological techniques may be appropriate interventions but should be guided by a specialist to ensure safe and effective pain management in a palliative care setting.

Correct answer:

In this scenario, the patient is presenting with acute exacerbation of chronic heart failure (CHF) complicated by pulmonary edema and respiratory distress. The priority intervention for managing this exacerbation is to initiate positive pressure ventilation for respiratory support. Positive pressure ventilation, such as non-invasive positive pressure ventilation (NIPPV) or invasive mechanical ventilation, can help improve oxygenation and decrease the work of breathing for the patient. By providing adequate respiratory support, ventilation can reduce the negative effects of pulmonary edema and respiratory distress due to CHF exacerbation. Administering intravenous loop diuretics (Choice A) might be necessary to address fluid overload, but it is not the initial priority as ensuring adequate ventilation is crucial. Emergent pericardiocentesis (Choice C) is not indicated in this scenario as there is no mention of cardiac tamponade. Inotropic medications (Choice D) may be considered in managing acute exacerbation of CHF but

Correct answer:

The correct answer is D because it encompasses all the key differences between first-degree and second-degree burns. A: A first-degree burn affects only the epidermis, while a second-degree burn affects both the epidermis and the dermis. This is correct as first-degree burns are superficial, affecting only the outer layer of the skin, while second-degree burns penetrate deeper into the dermis. B: A first-degree burn is characterized by redness and pain, while a second-degree burn is characterized by blisters and swelling. This is accurate as first-degree burns typically result in redness and pain, whereas second-degree burns involve blister formation and swelling due to damage to deeper skin layers. C: A first-degree burn heals within a few days, while a second-degree burn may take several weeks to heal. This is true as first-degree burns are minor and usually heal quickly, whereas second-degree burns require more time to heal due to the deeper tissue damage. Therefore, by considering all the distinctions

Correct answer:

In this scenario, the client is presenting with signs of sepsis, such as hypotension, hypothermia, and a recent history of partial-thickness burns with open wounds. The development of watery diarrhea further raises suspicion for sepsis. With a blood pressure of 82/40 mmHg and a low temperature of 96°F (36.6°C), the nurse should recognize the potential for septic shock. Notifying the rapid response team is crucial in this situation as the client requires immediate intervention and management to prevent deterioration and address the underlying septic process. Increasing the room temperature (Choice A) is not the priority as the low body temperature is likely due to systemic vasodilation and not environmental factors. While assessing oxygen saturation (Choice B) is important, the client's hypotension and hypothermia take precedence. Continuing to monitor vital signs (Choice C) alone is insufficient given the critical condition of the client and the need for prompt action to address the sepsis and potential septic shock.
