Theories of Health Behavior Change Questions
Question 1 of 5
A male client with inflammatory bowel disease undergoes an ileostomy. On the first day after surgery, Nurse Oliver notes that the client's stoma appears dusky. How should the nurse interpret this finding?
Correct Answer: A
Rationale: The correct answer is A: Blood supply to the stoma has been interrupted. A dusky appearance of the stoma indicates poor blood supply, which can lead to tissue ischemia and necrosis. This is a critical finding that requires immediate intervention to prevent further complications. In contrast, the other options are incorrect. Option B is incorrect because a dusky stoma is not a normal finding post-ileostomy surgery. Option C is incorrect as adjusting the ostomy bag will not address the underlying issue of compromised blood supply. Option D is incorrect as an intestinal obstruction would present with different symptoms and would not cause the stoma to appear dusky.
Question 2 of 5
When evaluating an arterial blood gas from a male client with a subdural hematoma, the nurse notes the Paco2 is 30 mm Hg. Which of the following responses best describes the result?
Correct Answer: A
Rationale: Rationale: - Correct answer (A): Paco2 of 30 mm Hg is appropriate because lowering CO2 helps reduce ICP in clients with subdural hematoma. - Incorrect answer (B): Paco2 is not indicative of oxygenation status; it measures CO2 levels. - Incorrect answer (C): Paco2 of 30 mm Hg is low, not normal. - Incorrect answer (D): Paco2 of 30 mm Hg indicates hyperventilation, not hypoventilation.
Question 3 of 5
Nurse Lourdes is teaching a client recovering from addisonian crisis about the need to take fludrocortisone acetate and hydrocortisone at home. Which statement by the client indicates an understanding of the instructions?
Correct Answer: C
Rationale: The correct answer is C because it demonstrates an understanding of the dosing schedule for both medications. Fludrocortisone acetate is usually taken in the morning to mimic the body's natural cortisol release, while hydrocortisone is typically taken in divided doses throughout the day to prevent adrenal insufficiency. Option C shows the client plans to take two-thirds of the dose in the morning and one-third in the late afternoon, aligning with the recommended dosing schedule. Option A is incorrect because taking hydrocortisone in the late afternoon is not ideal for mimicking the body's natural cortisol release. Option B is incorrect as taking all hydrocortisone in the morning may lead to suboptimal control of adrenal insufficiency throughout the day. Option D is incorrect because taking the entire dose at bedtime does not align with the recommended dosing schedules for these medications.
Question 4 of 5
Cleo is diagnosed with osteoporosis. Which electrolytes are involved in the development of this disorder?
Correct Answer: B
Rationale: The correct answer is B: Calcium and phosphorous. Osteoporosis is a condition characterized by weak and brittle bones. Calcium and phosphorous are essential minerals for bone health and strength. Calcium is a major component of bone tissue, while phosphorous plays a key role in bone mineralization. A deficiency in either of these electrolytes can lead to decreased bone density and increased risk of fractures. Sodium, potassium, and other electrolytes do not directly contribute to bone health in the same way that calcium and phosphorous do. Therefore, choices A, C, and D are incorrect as they do not involve the electrolytes crucial for bone health.
Question 5 of 5
Nurse Michelle calculates the IV flow rate for a postoperative client. The client receives 3,000 ml of Ringer's lactate solution IV to run over 24 hours. The IV infusion set has a drop factor of 10 drops per milliliter. The nurse should regulate the client's IV to deliver how many drops per minute?
Correct Answer: B
Rationale: To calculate the IV flow rate in drops per minute, we use the formula: (Drop factor x Volume to be infused in ml) / Time in minutes Given drop factor of 10, 3,000 ml to be infused over 24 hours (1,440 minutes), we get: (10 drops/ml x 3,000 ml) / 1,440 minutes = 21 drops/minute (Answer B). Choice A (18) is incorrect as it does not consider the correct drop factor and volume. Choice C (35) and D (40) are incorrect as they result from incorrect calculations.
