The nurse enters a male client's room to administer routine morning medications, and the client is on the phone. Which action is best for the nurse to take?

Correct Answer: B

Rationale: The best action for the nurse to take in this situation is to wait for the client to excuse himself from the telephone conversation and then observe the client taking the medication. This approach ensures that the client takes the medication as prescribed, promoting compliance and safety. Choice A is not ideal as it involves unnecessary delegation and may lead to confusion. Choice C is incorrect because assuming refusal without direct communication can compromise patient care. Choice D is not recommended as leaving the medication with the client unsupervised may result in non-compliance or potential errors.

Correct Answer: D

Rationale: The TENS unit works by providing a mild electrical stimulus to the skin, which helps to 'close the gate' on pain signals, reducing the perception of pain. Choice A is incorrect because distraction is not the primary mechanism of action for TENS. Choice B is incorrect as it describes a different method of pain management involving medication infusion into the spinal canal. Choice C is incorrect as it inaccurately describes the location of pain perception modulation by the TENS unit.

Correct Answer: A

Rationale: Hyperkalemia is the correct answer as it can lead to dangerous cardiac arrhythmias due to its effects on the electrical conduction of the heart. High levels of potassium can disrupt the normal electrical activity of the heart, potentially leading to life-threatening arrhythmias. Hypocalcemia (choice B) is not the most likely cause of cardiac arrhythmias compared to hyperkalemia. Hypernatremia (choice C), referring to high sodium levels, is not directly associated with causing cardiac arrhythmias. While hypokalemia (choice D), low potassium levels, can also lead to cardiac arrhythmias, hyperkalemia is the more likely culprit in causing severe disturbances in heart rhythm.

Correct Answer: D

Rationale: The correct intervention for a client in active labor complaining of a leg cramp is to extend the leg and flex the foot. This action helps stretch the muscles that are cramping, providing relief. Massaging the calf and foot (Choice A) may not be as effective for relieving the cramp. Elevating the leg above the heart (Choice B) is not indicated for a leg cramp. Checking the pedal pulse in the affected leg (Choice C) is unrelated to addressing the leg cramp.

Correct Answer: A

Rationale: The correct answer is A. Going over the surgical procedure with the patient is typically done preoperatively, not intraoperatively. Intraoperative tasks of a nurse involve strictly adhering to asepsis during procedures, monitoring the patient's physical status, and providing emotional support to the patient and their family during the surgery. Choices B, C, and D are all tasks that are directly related to the nurse's responsibilities during the intraoperative phase of care.

Correct Answer: A

Rationale: The practical nurse should record the findings and report the symptoms to the charge nurse. These behaviors may indicate a serious underlying condition such as depression or physical illness. By reporting to the charge nurse, the client can receive appropriate assessment and intervention promptly. Choice B is incorrect as family visits may not address the root cause of the symptoms. Choice C is incorrect as it oversimplifies the situation and may not be effective in addressing the underlying issue. Choice D is incorrect because withholding medications without proper assessment and guidance can be harmful to the client's health.

Correct Answer: B

Rationale: The correct answer is B: Ensuring the tracheostomy ties are secure. This is the nurse's first priority because it is critical to prevent accidental decannulation, which could compromise the patient's airway. Providing humidified oxygen, suctioning the tracheostomy tube, and monitoring for signs of infection are important aspects of care but ensuring the tracheostomy ties' security takes precedence to maintain the patient's airway.

Correct Answer: B

Rationale: A heart rate of 120 beats per minute is within the normal range for a 2-month-old infant. Therefore, it is safe to administer the digoxin and document the heart rate as part of routine care. Choice A is incorrect as withholding the medication is not necessary since the heart rate is normal. Choice C is incorrect as there is no need to delay the administration until the next scheduled dose when the heart rate is within the normal range. Choice D is incorrect as the primary nurse is not needed to administer the medication since the heart rate is normal and falls within the safe range for administration.

Correct Answer: B

Rationale: During an acute exacerbation of multiple sclerosis, it is important to encourage self-care to maintain the client's independence. Allowing rest periods helps prevent fatigue, which is crucial in managing MS exacerbations. Choice A is incorrect as hot baths can exacerbate symptoms in MS. Choice C is about communication techniques and not directly related to client care during an exacerbation. Choice D is not a priority intervention during an MS exacerbation.
