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 administering medications intravenously during advanced cardiac life-support interventions, it is crucial to understand the compatibility of different medications to prevent adverse reactions. The correct answer, option A, states that calcium chloride should not be administered through the same IV line as sodium bicarbonate because calcium chloride will precipitate or crystallize when mixed with sodium bicarbonate. This is important because the interaction between calcium chloride and sodium bicarbonate can lead to the formation of calcium carbonate precipitates, which can cause blockages in the IV line and potentially harm the patient by impeding the delivery of medications or causing emboli. Options B, C, and D are incorrect because they do not address the specific chemical reaction that occurs between calcium chloride and sodium bicarbonate. Understanding the chemical compatibility of medications is essential in clinical practice to ensure patient safety and the effectiveness of treatment. Educationally, this scenario highlights the importance of medication administration knowledge, especially in critical care situations. Healthcare providers must be aware of potential drug interactions and incompatibilities to prevent adverse outcomes for patients. Proper education and training on medication administration protocols can help healthcare professionals make informed decisions and provide safe and effective care.
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. Thiamine is essential for preventing Wernicke-Korsakoff syndrome, a condition characterized by severe memory issues and confusion that can result from thiamine deficiency, often seen in alcohol intoxication. Thiamine plays a crucial role in brain function and glucose metabolism. Administering thiamine first helps prevent this debilitating condition. Now, let's discuss why the other options are incorrect: - Option B) Ondansetron: Ondansetron is used to treat nausea and vomiting, which are not the immediate concerns in this case. - Option C) Narcan: Narcan is used to reverse opioid overdose, which is not indicated based on the presentation of low blood glucose. - Option D) Dextrose 50 percent (D50): While correcting low blood glucose is important, administering dextrose before thiamine can worsen Wernicke-Korsakoff syndrome in thiamine-deficient patients. Educational Context: Understanding the importance of administering thiamine first in cases of suspected alcohol intoxication with low blood glucose levels is vital for healthcare providers, especially when managing patients at risk for Wernicke-Korsakoff syndrome. This knowledge can prevent severe neurological complications and guide appropriate interventions in emergency situations.
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, option B, is the most appropriate means for confirming the placement of an NG tube in an intubated patient. Auscultating the epigastric region while injecting 20 to 30 mL of air into the NG tube is a reliable method to verify proper placement. When air is injected, a "whooshing" sound should be heard in the epigastric area if the tube is correctly positioned in the stomach. Option A is incorrect because relying solely on the pre-measurement black line at the nares does not guarantee proper placement within the gastrointestinal tract. Option C is incorrect as rolling the patient onto the left side and applying suction does not provide a definitive confirmation of tube placement. Option D is incorrect as watching for distension to decrease after attaching suction does not offer direct confirmation of NG tube placement. In an educational context, it is vital for healthcare providers to understand and apply proper techniques for confirming NG tube placement to prevent potential complications such as aspiration. Teaching this skill ensures patient safety and effective care delivery in various clinical settings. Remembering these key methods can help ensure accurate NG tube placement and provide optimal patient care.
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. When a patient presents with sudden-onset pain, coolness, pallor, and cramping in the lower extremity, it raises suspicion for acute arterial occlusion. The femoral artery supplies blood to the lower extremities, and occlusion can lead to severe ischemia and tissue damage. Prompt recognition and intervention are crucial to prevent complications like tissue necrosis or limb loss. Option B) Acute iliac artery occlusion is less likely in this case because the symptoms are localized to the right lower calf and not involving the entire leg or both legs. Option C) Acute abdominal aorta occlusion typically presents with severe abdominal pain and is not consistent with the symptoms described. Option D) Acute mesenteric artery occlusion presents with abdominal pain after eating due to inadequate blood supply to the intestines, which is not reflected in this case. Educationally, understanding the different presentations of arterial occlusions is vital for healthcare providers to provide timely and appropriate care. Recognizing the signs and symptoms of acute femoral artery occlusion can help prevent further complications and improve patient outcomes. This knowledge is crucial for nurses, physicians, and other healthcare professionals caring for patients at risk for vascular conditions.
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. Hemothorax refers to the presence of blood in the pleural cavity, which can lead to the absence of breath sounds due to the accumulation of blood obstructing the transmission of sound. Dullness to percussion occurs due to the presence of fluid or blood in the pleural space, which dampens the resonance of sound during percussion. Option B) Cardiac contusion is less likely to cause absence of breath sounds and dullness to percussion in the left hemithorax. Cardiac contusion typically presents with symptoms related to cardiac dysfunction rather than respiratory findings. Option C) Left simple pneumothorax is incorrect because pneumothorax (presence of air in the pleural space) typically presents with hyperresonance to percussion rather than dullness. Breath sounds may also be decreased but are typically decreased on the affected side. Option D) Left diaphragmatic rupture is less likely to cause absence of breath sounds and dullness to percussion over the left hemithorax. Diaphragmatic rupture can lead to bowel sounds in the chest cavity but would not typically present with absence of breath sounds and dullness to percussion. Educationally, understanding the characteristic signs and symptoms associated with different thoracic conditions is crucial for nurses caring for patients with Alzheimer's disease or any other population. This knowledge helps nurses assess and manage respiratory complications promptly and effectively, improving patient outcomes.
