Which of the following is the BEST method in assessing for the correct placement of the NGT?

Correct Answer: A

Rationale: In the context of assessing the correct placement of a nasogastric tube (NGT), the BEST method is using an X-ray. This is because an X-ray provides a definitive confirmation of the tube's location, ensuring it is in the stomach and not inadvertently in the lungs. Option B, immersing the tip of the tube in water to check for bubbles, is not a reliable method as it may not always accurately indicate proper placement. Option C, aspirating gastric content to check for acidity, can be misleading as it does not definitively confirm the tube's placement. Option D, instilling air in the NGT and listening for a gurgling sound, is not a recommended method as it may lead to misinterpretation and incorrect placement assumptions. From an educational standpoint, it is crucial for healthcare professionals to understand the importance of proper NGT placement to prevent complications such as aspiration pneumonia. Emphasizing the use of X-rays for confirmation ensures patient safety and effective care delivery. Relying on evidence-based practices and established protocols promotes accurate assessment and management in clinical settings.

Correct Answer: C

Rationale: The correct answer, option C (-120 to -150 mmHg), is the recommended suction pressure for adult endotracheal suctioning due to several important reasons. This range is selected to effectively remove secretions while minimizing trauma to the delicate mucosal lining of the trachea. Applying a suction pressure within this range ensures that an adequate amount of secretions is removed without causing damage or irritation to the airway. Options A, B, and D are incorrect for various reasons. Option A (0 to -80 mmHg) is too low to effectively remove secretions, potentially leaving behind respiratory secretions that can obstruct the airway. Option B (-80 to -120 mmHg) is also suboptimal as it may not provide enough suction force to clear the airway adequately. Option D (150 to 200 mmHg) is too high and poses a significant risk of causing trauma to the fragile mucosal lining of the trachea, leading to potential complications such as bleeding or inflammation. In an educational context, understanding the correct suction pressure for endotracheal suctioning is crucial for nursing students and healthcare professionals caring for patients requiring airway management. Proper suctioning techniques help maintain airway patency, prevent complications such as atelectasis or respiratory infections, and ensure optimal oxygenation. It is essential to adhere to evidence-based guidelines and recommendations to provide safe and effective care to patients with compromised respiratory function.

Correct Answer: C

Rationale: The correct answer is C) Increase inspiratory pause. In the given ABG results, the patient is experiencing metabolic acidosis (low HCO⁴‚ƒ) and hypoxemia (low PaO₂). By increasing the inspiratory pause during mechanical ventilation, more time is allowed for gas exchange to occur, improving oxygenation levels. This adjustment directly addresses the low PaO₂ value of 66, helping to enhance oxygen delivery to the patient's tissues. Option A) Decrease PIP is incorrect because altering peak inspiratory pressure would not directly address the underlying issue of hypoxemia and metabolic acidosis seen in the ABG results. Option B) Decreasing rise time is incorrect as it pertains to the speed at which pressure is delivered during inspiration, which is not the primary concern in this scenario related to oxygenation and acid-base balance. Option D) Increase respiratory rate is incorrect because simply increasing the respiratory rate may not necessarily improve oxygenation in this case. Addressing the underlying metabolic acidosis and optimizing gas exchange are more crucial for enhancing oxygen delivery. In an educational context, understanding how to interpret ABG values and make appropriate ventilator adjustments is essential for healthcare professionals, especially those working in critical care settings. This question highlights the importance of tailoring mechanical ventilation settings to address specific patient needs, such as optimizing oxygenation and correcting acid-base imbalances, to provide effective respiratory support.

Correct Answer: D

Rationale: In the context of oxygenation, understanding the different classes of medications used to manage respiratory conditions like COPD is crucial for nursing practice. The correct answer, D) Anoro Ellipta, is a combination medication that includes a Long-Acting Beta Agonist (LABA) called vilanterol and a Long-Acting Muscarinic Agent (LAMA) called umeclidinium. This combination is effective in providing bronchodilation and improving airflow in patients with COPD, ultimately enhancing oxygenation. Option A) Onbrez Breezhaler contains Indacaterol, which is a LABA but does not have the LAMA component required in the correct answer. Option B) Flovent Diskus contains fluticasone, a corticosteroid used for anti-inflammatory purposes, not a LABA or LAMA. Option C) Spiriva Respimat contains tiotropium, which is a LAMA but lacks the LABA component found in Anoro Ellipta. Educationally, understanding the mechanism of action of different respiratory medications is vital for nurses to appropriately administer and monitor their patients. Recognizing the specific components of combination therapies like Anoro Ellipta helps nurses tailor patient care to optimize oxygenation and manage respiratory conditions effectively. This knowledge also aids in patient education, ensuring they understand the purpose and proper use of their prescribed medications for optimal oxygenation and respiratory function.

Correct Answer: D

Rationale: In the context of oxygenation and its impact on stroke risk, it is crucial to understand that all of the options provided - diabetes mellitus, hypertension, and smoking - are indeed common risk factors for stroke. Diabetes mellitus predisposes individuals to stroke by causing damage to blood vessels over time, leading to atherosclerosis and increased risk of blood clots. Hypertension, on the other hand, puts strain on blood vessels, making them more susceptible to rupture or blockage, which can result in a stroke. Smoking is detrimental to cardiovascular health as it narrows blood vessels, raises blood pressure, and promotes the formation of blood clots. Therefore, option D, "All of the above," is the correct answer because each of these risk factors independently contributes to an increased likelihood of experiencing a stroke. Understanding these risk factors is essential for healthcare professionals to assess and educate patients on modifiable behaviors that can help reduce their risk of stroke. By recognizing and addressing these risk factors, individuals can take proactive steps to improve their cardiovascular health and lower their chances of suffering a stroke. This knowledge is vital for nurses, physicians, and other healthcare providers to effectively educate patients and implement preventive strategies in their care plans.
