Question 1 of 5
Terence suffered form burn injury. Using the rule of nines, which has the largest percent of burns?
Correct Answer: D
Rationale: The rule of nines is used to estimate the percentage of body surface area affected by burns. The upper trunk comprises 18% of the total body surface area, making it the largest single area. This is why choice D is the correct answer. The other choices are incorrect because the face and neck (choice A) represent 4.5%, the right upper arm and penis (choice B) represent 4.5%, and the right thigh and penis (choice C) represent 9%, which are all smaller percentages compared to the upper trunk.
Question 2 of 5
Mr. Mendoza who has suffered a cerebrovascular accident (CVA) is too weak to move on his own. To help the client avoid pressure ulcers, Nurse Celia should:
Correct Answer: A
Rationale: The correct answer is A: Turn him frequently. Turning the client frequently helps redistribute pressure, reducing the risk of pressure ulcers. This promotes circulation and relieves pressure on specific areas. Passive ROM exercises (B) are important for maintaining joint mobility but do not directly prevent pressure ulcers. Reducing fluid intake (C) is not recommended as hydration is crucial for skin health. Using a footboard (D) may help with positioning but is not as effective as regular turning for preventing pressure ulcers.
Question 3 of 5
A female client arrives at the emergency department with chest and stomach pain and a report of black tarry stool for several months. Which of the following order should the nurse Oliver anticipate?
Correct Answer: C
Rationale: The correct order to anticipate for the female client with chest and stomach pain and black tarry stool is option C. Firstly, an electrocardiogram is necessary to assess for any cardiac issues related to the chest pain. Next, a complete blood count is essential to evaluate for any potential blood disorders causing the black tarry stool. Testing for occult blood helps identify any gastrointestinal bleeding. Lastly, a comprehensive serum metabolic panel provides a broad assessment of the client's overall health status. Option A is incorrect as creatine kinase and lactate dehydrogenase levels are not typically indicated for the presenting symptoms. Option B focuses on coagulation parameters, which are not the primary concern in this case. Option D includes tests unrelated to the client's symptoms, making it an inappropriate choice.
Question 4 of 5
Norma asks for information about osteoarthritis. Which of the following statements about osteoarthritis is correct?
Correct Answer: C
Rationale: Rationale for Correct Answer (C): Osteoarthritis is the most common form of arthritis, affecting millions worldwide. It is characterized by the breakdown of cartilage in joints. This statement is correct as it accurately reflects the prevalence and impact of osteoarthritis. Summary of Incorrect Choices: A: Osteoarthritis can indeed be debilitating, especially in advanced cases, affecting mobility and quality of life. B: Osteoarthritis is not rare; it is prevalent, particularly in older populations. D: While osteoarthritis is more common in older adults, it can also affect people of all ages, including younger individuals due to factors like joint injury or genetics.
Question 5 of 5
Capillary glucose monitoring is being performed every 4 hours for a client diagnosed with diabetic ketoacidosis. Insulin is administered using a scale of regular insulin according to glucose results. At 2 p.m., the client has a capillary glucose level of 250 mg/dl for which he receives 8 U of regular insulin. Nurse Mariner should expect the dose's:
Correct Answer: C
Rationale: The correct answer is C. Regular insulin typically has an onset of action around 30 minutes after administration, with its peak action occurring around 2-4 hours later. In this case, the insulin was administered at 2 p.m., so the onset would be around 2:30 p.m. and the peak around 4 p.m. Option A is incorrect because the onset of action is not immediate at 2 p.m. and peak action happens later. Option B is incorrect as the onset would be closer to 2:30 p.m. Option D is incorrect as the peak action would not occur 2 hours after onset. Therefore, option C is the most appropriate based on the pharmacokinetics of regular insulin.
