Correct Answer: D

Rationale: In this scenario, the priority action is to notify the healthcare provider of the client's medication history. This is important because understanding the client's medication history, especially if they are taking anticoagulants or other medications that could affect bleeding and surgery, is crucial in ensuring safe management of the client's condition. Option A, ensuring the client is NPO and documenting the last meal, is important but not the priority in this situation. Administering pain medication (Option B) should only be done after ensuring the client's safety and stability. Applying a sterile dressing (Option C) is also important but not as critical as informing the healthcare provider of the medication history.

Correct Answer: D

Rationale: In a patient with COPD and HF, monitoring electrolyte levels is essential due to potential imbalances caused by medications or fluid shifts. Maintaining pulse oximetry is crucial to assess oxygenation status in COPD and HF. Providing assistance with mobility helps prevent deconditioning and complications. Therefore, all the actions mentioned are necessary for comprehensive care in this scenario, making option D the correct answer. Choices A, B, and C are all important aspects of managing COPD and HF, ensuring holistic and effective care.

Correct Answer: B

Rationale: The correct answer is B: Sensorineural. Ototoxic medications can lead to sensorineural hearing loss by affecting the inner ear or auditory nerve. Conductive hearing loss is related to issues in the middle or outer ear, not typically caused by ototoxic medications. Mixed hearing loss is a combination of conductive and sensorineural components. Central hearing loss is related to the central nervous system, not commonly caused by ototoxic medications. Therefore, in this case, the nurse should suspect sensorineural hearing loss.

Correct Answer: D

Rationale: The correct answer is D. Decreased frequency of ventricular tachycardia (VT) episodes indicates that the lidocaine infusion is effectively managing the ventricular tachycardia. Stabilization of BP ranges (choice A) may not directly correlate with the therapeutic response to lidocaine for VT. Cessation of chest pain (choice B) may indicate pain relief but does not specifically address the effectiveness of lidocaine for VT. Reduced heart rate (choice C) is not a direct indicator of the response to lidocaine for managing VT.

Correct Answer: C

Rationale: The most crucial instruction for a client with an indwelling urinary catheter post-bladder surgery is to keep the drainage bag positioned lower than the level of the bladder. This positioning prevents backflow of urine into the bladder, reducing the risk of infection. Choice A, avoiding coiling the tubing and keeping it free of kinks, is important to maintain proper flow but not as critical as ensuring the drainage bag is lower than the bladder. Choice B, cleansing the perineal area, is essential for overall hygiene but not directly related to catheter care instructions. Choice D, drinking fluids to irrigate the catheter, is not recommended as it may increase the risk of infection and should be guided by healthcare providers based on specific needs.
