A nurse is caring for a group of clients in a medical unit. Which of the following clients is at the highest risk for developing osmotic cerebral edema?
A client with a decreased potassium level
A client with a decreased serum glucose
A client with an increased hemoglobin A1C
A client with an increased creatinine level
None
None
The Correct Answer is B
Choice A Reason:
A client with a decreased potassium level is incorrect. Hypokalemia (decreased potassium level) can cause various neurological symptoms, but it doesn't directly lead to osmotic cerebral edema.
Choice B Reason:
When plasma glucose levels are rapidly lowered, an osmotic gradient develops between the brain and plasma, which can lead to cerebral edema. Brain cells pull water from the plasma, resulting in widespread edema.
Choice C Reason:
While HbA1c is an important marker of diabetes control and may indicate poor long-term management, it does not directly relate to the acute metabolic derangements (e.g., rapid osmotic shifts, severity of acidosis) that predispose to cerebral edema in DKA.
Choice D Reason:
A client with an increased creatinine level is incorrect. Elevated creatinine levels typically indicate kidney dysfunction or dehydration, but they don't directly cause osmotic cerebral edema.

Correct Answer is ["B","C","D","E"]
Explanation
Choice A Reason:
Obtaining a hospital bed and keeping all four siderails up, may not be the best choice. While a hospital bed with siderails may be appropriate for some individuals with Parkinson's disease who are at high risk of falls, keeping all four siderails up continuously can potentially restrict mobility and independence. It's important to balance safety with the client's comfort and ability to move independently.
Choice B Reason:
Removing all throw rugs from the home is correct. Throw rugs can be tripping hazards, especially for individuals with mobility issues or balance problems. Removing throw rugs can reduce the risk of trips and falls within the home.
Choice C Reason:
Installing handrails in the bathroom is correct. Installing handrails in the bathroom, especially near the toilet and shower, can provide additional support and stability for individuals with Parkinson's disease when performing daily activities. This can help prevent falls in a potentially slippery environment.
Choice D Reason:
Ensuring adequate lighting along walking spaces is correct. Good lighting is crucial for individuals with Parkinson's disease to see obstacles and hazards clearly. Adequate lighting along walking spaces helps improve visibility and reduces the risk of falls, especially during nighttime or low-light conditions.
Choice E Reason:
Keeping walking areas free of clutter is correct. Clutter and obstacles in walking areas increase the risk of tripping and falling, particularly for individuals with Parkinson's disease who may have difficulty with balance and coordination. Keeping walking areas clear of clutter helps create a safer environment.
Correct Answer is ["B","C","D","E"]
Explanation
Choice A Reason:
Pleural cavity decompression via needle aspiration is inappropriate. Pleural cavity decompression via needle aspiration may be indicated in cases of tension pneumothorax, a potentially life-threatening condition in which air accumulates in the pleural space and compresses the lung. While it is an intervention rather than a diagnostic tool, it may be performed emergently if tension pneumothorax is suspected based on clinical findings.
Choice B Reason:
Focused assessment with sonography in trauma (FAST) is appropriate. FAST is a bedside ultrasound examination commonly used in trauma settings to rapidly assess for the presence of free fluid in the pericardial, pleural, and peritoneal spaces. It can help identify hemopericardium, hemothorax, or intra-abdominal hemorrhage, which may be indicative of thoracic injury.
Choice C Reason:
Chest x-ray is appropriate. Chest x-ray is a commonly used imaging modality for evaluating thoracic injuries. It can help visualize abnormalities such as rib fractures, pneumothorax, hemothorax, pulmonary contusions, or other traumatic injuries to the chest.
Choice D Reason:
Thoracentesis is appropriate. Thoracentesis is a procedure used to sample fluid from the pleural space for diagnostic or therapeutic purposes. It may be indicated if there is a suspicion of pleural effusion or if fluid accumulation is seen on imaging studies such as chest x-ray or ultrasound.
Choice E Reason:
Ultrasound is appropriate. Ultrasound can be used to evaluate various aspects of thoracic injuries, including the presence of pneumothorax, hemothorax, or pleural effusion. It is often used as part of the FAST examination but can also be performed separately for more detailed assessment.
