1. A client is evaluated by a nurse regarding the use of a sequential compression device. Which of the following client statements indicates understanding of the device's purpose?

Correct answer: B

Rationale: The correct answer is B because sequential compression devices are utilized to enhance circulation and prevent clot formation in the legs. Option A is incorrect because these devices are not primarily meant to prevent skin sores. Option C is incorrect because the devices do not directly address muscle weakness. Option D is incorrect as the main purpose of sequential compression devices is not related to joint health.

2. What is the most important assessment for the LPN/LVN to perform on a client with a history of chronic obstructive pulmonary disease (COPD) receiving oxygen therapy at 2 liters per minute via nasal cannula?

Correct answer: B

Rationale: Measuring the client's oxygen saturation level is the most important assessment in this scenario. Oxygen saturation level reflects how well the client is oxygenating, which is crucial in assessing the effectiveness of oxygen therapy for a client with COPD. Monitoring the respiratory rate and effort (Choice A) is important but assessing oxygenation with saturation levels takes precedence. While arterial blood gas levels (Choice C) provide comprehensive information, checking oxygen saturation is a quicker and more immediate way to assess oxygenation status. Checking blood pressure (Choice D) is not the priority when evaluating the effectiveness of oxygen therapy in COPD.

3. The healthcare professional is evaluating the body alignment of a patient in the sitting position. Which observation will indicate a normal finding?

Correct answer: B

Rationale: In a normal sitting position, both feet should be supported on the floor with the ankles comfortably flexed. This position helps in maintaining stability and proper alignment. Choice A is incorrect because the edge of the seat pressing against the popliteal space may cause discomfort and is not indicative of proper alignment. Choice C is incorrect as the body weight should be evenly distributed for proper alignment and comfort, not solely on the buttocks. Choice D is incorrect as the position of the arms alone does not indicate proper body alignment in the sitting position; proper arm positioning is important for comfort but not a key indicator of body alignment.

4. A healthcare professional is preparing to administer dextrose 5% in water (D5W) 1,000-mL IV to infuse over 10 hr. How many mL/hr should the IV infusion pump be set to deliver? (Round the answer to the nearest whole number. Do not use a trailing zero.)

Correct answer: A

Rationale: To infuse 1,000 mL over 10 hr, the IV pump should be set to deliver 100 mL/hr. This calculation is derived by dividing the total volume (1,000 mL) by the total time in hours (10 hr), resulting in the infusion rate of 100 mL/hr. Choices B, C, and D are incorrect as they do not accurately reflect the correct calculation for this scenario.

5. During an assessment, a healthcare professional is evaluating the body alignment of a standing patient. Which finding will the healthcare professional report as normal?

Correct answer: A

Rationale: During a standing assessment, the healthcare professional should observe the patient laterally. In a normal body alignment, the head is erect, and the spinal curves align in a reversed 'S' pattern, aiding in maintaining balance and posture. Choice B is incorrect because hips and shoulders should be level and not form an 'S' pattern when observed posteriorly. Choice C is incorrect as the position of the arms is not a key indicator of body alignment. Choice D is incorrect as the feet should be shoulder-width apart with toes pointing forward for optimal balance and stability.
