Correct Answer: A

Rationale: The correct rate of delivery is 107 mL/hr. To find the rate of delivery, divide the total volume by the total time: 750 mL / 7 hours = 107 mL/hr. Choice B, C, and D are incorrect as they do not match the correct calculation based on the total volume and time provided.

Correct Answer: A

Rationale: Assessing the client's sleep and activity patterns is crucial in understanding the factors contributing to the sleep difficulties and headaches. By evaluating these patterns, the nurse can identify triggers, stressors, and lifestyle habits that may be impacting the client's sleep quality and overall well-being. This assessment will guide the nurse in formulating an appropriate care plan tailored to the client's specific needs. Option B is not appropriate as it focuses solely on providing medication without addressing underlying issues. Option C is premature as a thorough assessment should precede any referrals for specialized studies. Option D, while important, should come after understanding the client's sleep patterns to provide more targeted coping strategies.

Correct Answer: D

Rationale: The correct answer is D. Eating foods high in potassium can lead to hyperkalemia when taken with digoxin, indicating a need for further teaching. Choices A, B, and C are all correct statements that demonstrate understanding of digoxin therapy. Taking the pulse, maintaining a consistent dosing schedule, and avoiding antacids to prevent interactions with digoxin are all appropriate client responses.

Correct Answer: B

Rationale: The correct action for the nurse to take when measuring a client's oral temperature using an electronic thermometer is to inquire whether the client has smoked in the last 30 minutes. Smoking can affect the accuracy of oral temperature readings. Providing oral hygiene (Choice A) is not directly related to ensuring accurate temperature measurement. Connecting the red tip probe (Choice C) is not specific to oral temperature measurement accuracy. Positioning the probe tip against the buccal mucosa (Choice D) is incorrect as oral temperature is typically measured under the tongue, not against the cheek.

Correct Answer: A

Rationale: The correct answer is to repeat each joint motion five times during each session. Repetition is crucial to maintaining joint flexibility and muscle function. By ensuring each joint motion is repeated, the client can benefit fully from the passive range-of-motion exercises. Choice B is incorrect because quick performance may compromise technique and risk injury. Choice C is incorrect as neglecting less affected joints can lead to imbalances and hinder overall progress. Choice D is incorrect as assessing the client's range of motion beforehand is vital, but it is not the immediate action to take during the exercise session.
