Care of Patients with Alzheimers Disease Basic Concept ATI Questions
Question 1 of 5
Your adult patient has suffered a prolonged cardiac arrest interval and is receiving advanced cardiac life-support interventions. When administering medications intravenously, why should calcium chloride and sodium bicarbonate not be administered through the same IV line?
Correct Answer: A
Rationale: In the context of caring for a patient with Alzheimer's Disease, understanding the principles of medication administration during advanced cardiac life-support interventions is crucial for providing safe and effective care. The correct answer is A) Calcium chloride will precipitate/crystallize when mixed with sodium bicarbonate. This is because when calcium chloride, which is a cation, comes into contact with sodium bicarbonate, which is an anion, they can form a precipitate or crystals that can potentially lead to blockages in the IV line, compromising the delivery of essential medications to the patient. Option B) Calcium chloride will antagonize the effects of sodium bicarbonate is incorrect because these two medications do not directly counteract each other's effects. Option C) Sodium bicarbonate will cause a rebound acidosis when mixed with calcium chloride is incorrect as mixing these two substances does not lead to a rebound acidosis. Option D) Sodium bicarbonate will act as an agonist to the calcium chloride causing hypercalcemia is incorrect as sodium bicarbonate does not act as an agonist to calcium chloride, nor does it cause hypercalcemia. Educationally, it is vital for healthcare professionals to understand the compatibility and incompatibility of medications when administering them intravenously to prevent adverse reactions and ensure the optimal delivery of treatment to patients, especially those in critical conditions like prolonged cardiac arrest intervals. This knowledge helps in maintaining patient safety and promoting successful outcomes in clinical practice.
Question 2 of 5
You are on-scene with an unconscious adult female who you suspect may be intoxicated. The patient's vital signs are within normal limits; however, her blood glucose level is low. Which of the following should be administered first to prevent Wernicke-Korsakoff syndrome, after initiating oxygen therapy and IV access?
Correct Answer: A
Rationale: In this scenario, the correct answer is A) Thiamine. Administering thiamine first is crucial in preventing Wernicke-Korsakoff syndrome in patients with low blood glucose levels. Thiamine is essential for glucose metabolism, and in cases of low blood glucose, the body's thiamine stores can become depleted rapidly. Wernicke-Korsakoff syndrome is a neurological disorder caused by thiamine deficiency, and prompt administration of thiamine can prevent its development. Option B) Ondansetron is used to treat nausea and vomiting, which are not the primary concerns in this case. Option C) Narcan is used to reverse opioid overdose, which is not indicated in a patient with low blood glucose. Option D) Dextrose 50 percent (D50) may seem appropriate for low blood glucose; however, administering dextrose without thiamine can exacerbate or precipitate Wernicke-Korsakoff syndrome in patients with thiamine deficiency. In an educational context, understanding the importance of thiamine administration in patients with suspected alcohol intoxication and low blood glucose levels is crucial for healthcare providers. Recognizing the risk of Wernicke-Korsakoff syndrome and the role of thiamine in preventing it underscores the significance of prompt and appropriate interventions in such cases.
Question 3 of 5
You have just inserted a nasogastric (NG) tube in your intubated patient to relieve gastric distension. Which of the following confirmation means is most appropriate for determining the placement of an NG tube?
Correct Answer: B
Rationale: The correct answer is option B: Auscultate the epigastric region while injecting 20 to 30 mL of air into the NG tube. This method is the most appropriate for determining NG tube placement because it utilizes a reliable and commonly accepted technique. By injecting air and auscultating the epigastric region, healthcare providers can listen for a "whoosh" sound, indicating that the tube is in the stomach and not the lungs. This method is safer and more accurate compared to the other options. Option A is incorrect because relying solely on the pre-measurement black line at the nares does not guarantee proper placement, as the tube could still be in the lungs. Option C is incorrect because rolling the patient and applying suction is not a reliable method for confirming NG tube placement. Option D is incorrect because watching for distension to decrease after attaching suction does not confirm the tube's location in the stomach. In an educational context, it is crucial for healthcare providers to understand and utilize evidence-based practices for patient care. Proper NG tube placement is critical to prevent complications such as aspiration. By mastering techniques like auscultation after air injection, caregivers can ensure safe and effective patient care in scenarios like gastric distension in intubated patients.
Question 4 of 5
You are called to assist a 50-year-old patient with rapid-onset pain in his right lower calf. The patient denies trauma but has a past medical history of hypertension and heart disease. The right lower leg is cool and pale, and the patient reports cramp-like pain in the area that began while he was sitting. His left leg remains asymptomatic. Which of the following conditions should be suspected until proven otherwise?
Correct Answer: A
Rationale: In this scenario, the correct answer is A) Acute femoral artery occlusion. This condition should be suspected until proven otherwise due to the patient's symptoms of rapid-onset pain in the right lower calf, cool and pale extremity, and cramp-like pain. These symptoms are indicative of a potential arterial occlusion, specifically in the femoral artery, which is a critical blood vessel supplying the lower extremities. Option B) Acute iliac artery occlusion is less likely in this case because the symptoms are localized to the right lower calf, suggesting a more distal occlusion in the femoral artery rather than a more proximal occlusion in the iliac artery. Option C) Acute abdominal aorta occlusion typically presents with more diffuse and severe symptoms affecting multiple lower extremities, as opposed to the unilateral symptoms described in the scenario. Option D) Acute mesenteric artery occlusion would manifest with symptoms related to abdominal pain and potential bowel ischemia, which are not consistent with the patient's presentation of pain in the right lower calf. From an educational perspective, understanding the importance of prompt recognition and differentiation of acute arterial occlusions is crucial in the care of patients with cardiovascular conditions. Recognizing the specific symptoms and appropriate differential diagnosis can lead to timely intervention and prevention of serious complications such as limb ischemia or necrosis. This case highlights the significance of clinical reasoning and assessment skills in providing optimal care for patients with acute vascular issues.
Question 5 of 5
Absence of breath sounds and dullness to percussion over the left hemithorax are best explained by:
Correct Answer: A
Rationale: In this scenario, the correct answer is A) Left hemothorax. When a patient presents with absence of breath sounds and dullness to percussion over the left hemithorax, it indicates the presence of fluid or blood in the pleural space, characteristic of a hemothorax. This condition can result from trauma or injury to the chest, leading to bleeding into the pleural cavity, which in turn causes the lung to collapse partially or completely. Option B) Cardiac contusion is incorrect because it typically presents with symptoms related to the heart, such as chest pain, arrhythmias, or cardiac dysfunction, rather than respiratory findings like absent breath sounds and dullness to percussion. Option C) Left simple pneumothorax is incorrect as it would manifest with decreased or absent breath sounds but hyperresonance to percussion due to the presence of air in the pleural space, not fluid or blood as seen in a hemothorax. Option D) Left diaphragmatic rupture is incorrect because it would present with other signs such as bowel sounds in the chest, not just absence of breath sounds and dullness to percussion over the left hemithorax. In an educational context, understanding the pathophysiology and clinical manifestations of different thoracic conditions is crucial for nurses caring for patients with respiratory or chest trauma. Recognizing these signs and symptoms promptly is vital for initiating appropriate interventions and preventing further complications in patients with thoracic injuries.
