1. Which of the following is the best method for confirming nasogastric tube placement?

• A. Auscultating over the stomach while injecting air
• B. Checking the pH of the aspirate
• C. Observing the patient’s response during feeding
• D. Measuring the external length of the tube

Correct answer: B

Rationale: Checking the pH of the aspirate is the most reliable method to confirm nasogastric tube placement as it provides direct evidence of the tube's location in the stomach. When the pH is acidic (pH < 5), it indicates that the tube is correctly placed in the stomach. Auscultating over the stomach while injecting air may not always be accurate, as the sound can be misleading due to various factors. Observing the patient’s response during feeding is not a definitive method for confirming tube placement, as it can be influenced by other factors. Measuring the external length of the tube does not ensure correct placement within the GI tract and can be affected by external factors like patient anatomy.

2. After adding feeding solution to a client's tube feeding system as seen in the picture, what action should the PN take next?

• A. Remove the air from the solution bag
• B. Obtain a piston syringe and irrigation set
• C. Record the solution added as fluid intake
• D. Calculate the rate of flow of the solution

Correct answer: B

Rationale: After adding feeding solution, obtaining a piston syringe and irrigation set is necessary to flush the feeding tube and ensure patency before starting the feeding. This helps prevent blockages and ensures proper delivery of the nutritional solution. Option A is incorrect because removing air from the solution bag is not the immediate next step after adding the feeding solution. Option C is incorrect as recording the solution added as fluid intake is important but not the immediate next step. Option D is incorrect as calculating the rate of flow of the solution is not the next step after adding the feeding solution.

3. Which type of cell is responsible for producing antibodies in the immune system?

• A. B lymphocytes
• B. T lymphocytes
• C. Macrophages
• D. Neutrophils

Correct answer: A

Rationale: The correct answer is A: B lymphocytes. B lymphocytes (B cells) are a crucial part of the adaptive immune system. They produce antibodies, which are proteins that specifically target and neutralize pathogens such as bacteria and viruses. T lymphocytes (choice B) are involved in cell-mediated immunity rather than antibody production. Macrophages (choice C) are phagocytic cells that engulf and digest pathogens but do not produce antibodies. Neutrophils (choice D) are a type of white blood cell that primarily function in the innate immune response by phagocytosing pathogens.

4. What is the first step in using an automated external defibrillator (AED) on a patient who has collapsed?

• A. Apply the pads to the chest
• B. Turn on the AED and follow the voice prompts
• C. Check the patient's pulse
• D. Ensure the area is clear before delivering a shock

Correct answer: B

Rationale: The correct answer is B: Turn on the AED and follow the voice prompts. This is the first step in using an AED as the device will guide you through the process of analyzing the heart rhythm and delivering a shock if necessary. Choice A, applying the pads to the chest, comes after turning on the AED. Checking the patient's pulse (Choice C) is not necessary before using an AED as the device is specifically designed to assess the need for defibrillation. Ensuring the area is clear (Choice D) is important for safety but is not the initial step in using an AED.

5. A full-term, 24-hour-old infant in the nursery regurgitates and suddenly turns cyanotic. Which immediate intervention should the PN implement?

• A. Stimulate the infant to cry
• B. Give oxygen by positive pressure
• C. Suction the oral and nasal passages
• D. Turn the infant onto the right side

Correct answer: C

Rationale: Suctioning the oral and nasal passages is the correct immediate intervention in this scenario. Regurgitation leading to cyanosis indicates a potential airway obstruction, which requires prompt action to clear. Stimulating the infant to cry (Choice A) may not address the underlying issue of airway obstruction. Giving oxygen by positive pressure (Choice B) can be beneficial, but clearing the airway obstruction takes precedence. Turning the infant onto the right side (Choice D) does not directly address the need to clear the airway.
