Theories of Health Behavior Change Questions
Question 1 of 5
For a diabetic male client with a foot ulcer, the doctor orders bed rest, a wet-to-dry dressing change every shift, and blood glucose monitoring before meals and bedtime. Why are wet-to-dry dressings used for this client?
Correct Answer: C
Rationale: The correct answer is C because wet-to-dry dressings are used to debride the wound by removing necrotic tissue and promoting healing by secondary intention. Here's the rationale: 1. Wet-to-dry dressings involve moistening the gauze dressing with saline solution before placing it on the wound. 2. As the dressing dries, it adheres to the wound bed and necrotic tissue, helping to remove it during dressing changes. 3. This debridement process helps in promoting healing by allowing healthy tissue to grow and fill in the wound. 4. The wet-to-dry dressing method is specifically indicated for wounds with necrotic tissue, like foot ulcers in diabetic clients. In summary, the other choices are incorrect because A focuses on maintaining a moist environment, B on protecting the wound, and D on preventing infection and minimizing discomfort, which are not the primary purposes of wet-to-dry dressings in this context.
Question 2 of 5
While monitoring a client for the development of disseminated intravascular coagulation (DIC), the nurse should take note of what assessment parameters?
Correct Answer: A
Rationale: Rationale: 1. Platelet count: DIC causes excessive clotting leading to platelet consumption. 2. Prothrombin time (PT): Evaluates the extrinsic pathway of coagulation, prolonged in DIC. 3. Partial thromboplastin time (PTT): Assesses intrinsic pathway, also prolonged in DIC. Therefore, A is correct for monitoring DIC. Summary: B is incorrect because blood glucose and WBC count are not directly related to DIC. C is incorrect as thrombin time, calcium, and potassium levels are not specific to DIC. D is incorrect as fibrinogen level is not included in standard DIC monitoring.
Question 3 of 5
Nurse Evangeline teaches an elderly client how to use a standard aluminum walker. Which of the following behaviors, if demonstrated by the client, indicates that the nurse's teaching was effective?
Correct Answer: A
Rationale: The correct answer is A because it demonstrates the proper technique for using a standard aluminum walker. By pushing the walker forward 12 inches first and then taking small steps while leaning on the walker, the client ensures stability and support. This method helps prevent falls and promotes safe mobility. Option B is incorrect because lifting the walker may lead to instability and increase the risk of falling. Option C is incorrect because supporting weight on the walker while advancing may not provide adequate support. Option D is incorrect because sliding the walker forward may cause the client to lose balance and stability.
Question 4 of 5
Nurse Ron begins to teach a male client how to perform colostomy irrigations. The nurse would evaluate that the instructions were understood when the client states, "I should:
Correct Answer: B
Rationale: The correct answer is B because keeping the irrigating container less than 18 inches above the stoma helps regulate the flow rate of the solution, preventing discomfort or damage to the stoma. Placing the container too high can cause rapid flow, leading to cramping or leakage. Choices A, C, and D are incorrect. Choice A is incorrect because the client should actually lie on his back, not the left side, to facilitate the irrigation process. Choice C is incorrect as instilling too much solution can cause discomfort or damage to the bowel. Choice D is incorrect because the client should not insert the catheter deeper if cramping occurs, as this could cause injury to the bowel.
Question 5 of 5
Nurse Tristan is caring for a male client in acute renal failure. The nurse should expect hypertonic glucose, insulin infusions, and sodium bicarbonate to be used to treat:
Correct Answer: C
Rationale: The correct answer is C, hyperkalemia. In acute renal failure, the kidneys are unable to excrete potassium effectively, leading to elevated levels in the blood. Hypertonic glucose with insulin helps shift potassium into the cells, reducing blood levels. Sodium bicarbonate can also help by correcting acidosis, which can worsen hyperkalemia. A: Hypernatremia involves high sodium levels, treated with fluid restriction or diuretics. B: Hypokalemia is low potassium levels, treated with potassium supplementation. D: Hypercalcemia is high calcium levels, treated with hydration and medications to lower calcium levels.
