Question 1 of 5
A nurse is preparing to administer acetaminophen 10 mg/kg/dose to a child who weighs 28 lb. The amount available is acetaminophen 120 mg/5 mL. How many ml should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 5.3
Rationale:
To calculate the correct dose, we first convert the child's weight from lb to kg: 28 lb / 2.2 = 12.73 kg.
Then, we multiply the weight by the dose (10 mg/kg): 12.73 kg * 10 mg/kg = 127.3 mg. Next, we convert mg to mL using the available concentration: 127.3 mg / 120 mg = 1.06 mL, which rounds to 1 decimal place as 5.3 mL.
Therefore, the nurse should administer 5.3 mL. Other choices are incorrect because they do not follow the correct conversion and calculation steps, leading to inaccurate dosing.
Question 2 of 5
A nurse is teaching the family of a client who is receiving treatment for a spinal cord injury with a halo fixation device. Which of the following statements should the nurse make?
Correct Answer: B
Rationale: The correct answer is B: The purpose of this device is to immobilize the cervical spine. The halo fixation device is used to stabilize and immobilize the cervical spine to promote proper healing. Allowing neck movement (
A) would counteract the purpose of the device. Turning screws daily (
C) could lead to complications. Applying talcum powder (
D) is not necessary and may cause skin irritation.
Question 3 of 5
A nurse is caring for a client who has global aphasia. Which of the following actions should the nurse take?
Correct Answer: B
Rationale: The correct answer is B: Speak to the client about one idea at a time. Global aphasia impairs the ability to understand and communicate effectively. By speaking about one idea at a time, the nurse helps the client focus and process information easier. This approach reduces confusion and frustration for the client.
Choice A is incorrect because multitasking can overwhelm someone with global aphasia.
Choice C is incorrect as using multiple forms of communication may be too challenging.
Choice D is incorrect as limiting questions to yes and no may not address the client's needs fully.
Question 4 of 5
A nurse who is mentoring a graduate nurse explains the correlation between severe blood loss and the effect on the client's mean arterial pressure (MAP). The graduate nurse demonstrates correct understanding when he states which of the following:
Correct Answer: D
Rationale: The correct answer is D: Lower blood volume lowers MAP. Mean Arterial Pressure (MAP) is determined by cardiac output and systemic vascular resistance. Severe blood loss results in decreased blood volume, leading to a decrease in cardiac output. With lower cardiac output, there is less blood being pumped into the arteries, resulting in lower pressure exerted on the arterial walls, hence lowering the MAP.
Choices A and B are incorrect as severe blood loss reduces cardiac output and would not raise it or cause vasoconstriction.
Choice C is incorrect as there is a direct correlation between blood loss and MAP.
Question 5 of 5
A nurse assesses a client with a brain injury. The client opens his eyes when the nurse calls his name, does not understand questions, and brings his arm up in response to a trapezius squeeze by the nurse. How would the nurse document this client's assessment using the Glasgow Coma Scale?
Correct Answer: D
Rationale: The correct answer is D: 9. The Glasgow Coma Scale (GCS) assesses eye opening, verbal response, and motor response. In this scenario, the client opens his eyes in response to a stimulus (4 points), has no verbal response (1 point), and exhibits localizing pain motor response by bringing his arm up to the trapezius squeeze (4 points). This totals 9 points on the GCS, indicating a moderate level of consciousness.
Choices A, C, and G are incorrect as they do not accurately reflect the client's assessment findings.
Choice B is incorrect as a score of 1 on the GCS indicates the lowest level of consciousness.
