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. When teaching a patient about the side effects of a new medication, which teaching method is most effective?

• A. Providing a written pamphlet
• B. Giving verbal instructions only
• C. Demonstrating how to take the medication
• D. Using a combination of verbal, written, and demonstration methods

Correct answer: D

Rationale: The most effective teaching method when educating a patient about the side effects of a new medication is to use a combination of verbal, written, and demonstration methods. This comprehensive approach ensures that the patient receives information through multiple channels, catering to different learning styles. Verbal instructions allow for direct communication, written materials provide a reference for the patient to review later, and demonstrations offer a visual aid that can enhance understanding. Providing a combination of these methods increases the likelihood of the patient retaining and comprehending the information effectively. Choices A, B, and C are less effective as they do not encompass the benefits of utilizing multiple teaching modalities.

3. Which laboratory value is most important to monitor for a patient receiving heparin therapy?

• A. Platelet count
• B. Prothrombin time (PT)
• C. Partial thromboplastin time (PTT)
• D. International normalized ratio (INR)

Correct answer: C

Rationale: The correct answer is C, Partial thromboplastin time (PTT). PTT is monitored to assess the therapeutic effect of heparin therapy. It helps ensure that the heparin levels are within the desired range to prevent either clotting or excessive bleeding. Platelet count (A) is important but does not directly assess heparin's therapeutic effect. Prothrombin time (PT) (B) and International normalized ratio (INR) (D) are used to monitor patients on warfarin, not heparin therapy.

4. What is the primary cause of diabetic ketoacidosis (DKA)?

• A. Insulin deficiency
• B. Overhydration
• C. Excess carbohydrate intake
• D. Excess insulin

Correct answer: A

Rationale: The correct answer is A: Insulin deficiency. Diabetic ketoacidosis occurs due to a severe lack of insulin, causing the body to break down fat for energy, leading to the production of ketones and acidification of the blood. Option B, Overhydration, is incorrect as DKA is characterized by dehydration rather than overhydration. Option C, Excess carbohydrate intake, is incorrect because while high blood sugar levels can contribute to DKA, the primary cause is insulin deficiency. Option D, Excess insulin, is also incorrect as DKA is not caused by an excess of insulin but rather by a lack of it.

5. The PN reviews a client's medication history and learns that the client takes an anticoagulant and has recently started taking phenytoin. Which instruction should the PN provide when assigning the client's morning care to a UAP?

• A. Measure the temperature every 4 hours
• B. Elevate both feet on two pillows
• C. Initiate hourly turning schedule
• D. Protect skin from injury and bruising

Correct answer: D

Rationale: The correct answer is D: Protect skin from injury and bruising. Phenytoin and anticoagulants both increase the risk of bleeding. Protecting the skin from injury and bruising is critical to prevent complications, making it important to instruct the UAP accordingly. Measuring the temperature every 4 hours (Choice A) may not be directly related to the client's medications. Elevating both feet on two pillows (Choice B) is more relevant for issues like edema. Initiating an hourly turning schedule (Choice C) is important for preventing pressure ulcers, but in this case, the priority is to prevent bleeding due to the medications.
