Correct Answer: D

Rationale: When caring for a comatose client, it is crucial to monitor and maintain the integrity of the indwelling urinary catheter to prevent urinary tract infections and other complications. Changing the urinary catheter less frequently than recommended increases the risk of infection. In this scenario, the most concerning issue is the prolonged duration since the last change of the indwelling urinary catheter, which poses an immediate risk to the client's health. While repositioning every 2 hours is essential to prevent skin breakdown, the most critical aspect in this case is the catheter care. Bathing and skin assessment are important for overall hygiene and skin integrity but are not as urgent as catheter care. The timing of the PEG tube change, while relevant for care planning, is not as immediate a concern as the indwelling urinary catheter status.

Correct Answer: A

Rationale: A high ammonia level can lead to hepatic encephalopathy, which includes symptoms like confusion, disorientation, and can progress to coma. Coma is a severe condition of unconsciousness. Edema is swelling caused by excess fluid trapped in body tissues, not typically associated with high ammonia levels. Hypoxia is a condition of inadequate oxygen supply to tissues and organs, not directly related to high ammonia levels. Polyuria is excessive urination, which is not a typical sign of high ammonia levels.

Correct Answer: A

Rationale: The correct instruction for a client undergoing mammography is not to use underarm deodorant. Underarm deodorant can cause confusing shadows on the X-ray film, affecting the accuracy of the mammogram. Choices B, C, and D are incorrect. While wearing comfortable clothing is advisable, it is not the primary instruction for mammography. Avoiding caffeine and bringing a list of current medications are not specific instructions related to mammography preparation and are therefore not the correct answers.

Correct Answer: D

Rationale: The nurse acts as an advocate for the nursing profession by encouraging appropriate persons to become nurses, by being a positive role model and mentor, and by communicating the needs of nurses in the most professional manner possible to those making the laws. Encouraging as many persons as possible to become nurses may not align with the advocacy role, as the focus should be on quality rather than quantity. Choices A, B, and C are activities that align with being an advocate for the nursing profession by promoting political involvement, providing first aid, and precepting newly licensed nurses, respectively.

Correct Answer: B

Rationale: The correct answer is 'Risk for Injury.' Epileptic clients are at risk for injury due to complications of seizure activity, such as falls that could lead to head trauma. 'Dysreflexia' is not typically associated with epilepsy but rather with spinal cord injury. 'Urinary Retention' is not a common nursing diagnosis for epileptic clients unless specifically indicated. 'Unbalanced Nutrition' may not be a priority nursing diagnosis compared to the immediate risk of injury in epileptic clients.
