Which of the following could the nurse expect to observe in an older adult client who has a pneumothorax?
A. Higher oxygen saturations of 98% to 99%
Higher oxygen saturations of 98% to 99% is inappropriate. A pneumothorax involves the presence of air in the pleural space, which can compromise lung function and gas exchange. This compromised lung function typically leads to decreased oxygenation of the blood, resulting in lower oxygen saturations rather than higher saturations.
B. Lower oxygen saturations of 93% to 94%
Lower oxygen saturations of 93% to 94% is appropriate. A pneumothorax disrupts the normal exchange of oxygen and carbon dioxide in the lungs due to partial or complete lung collapse. As a result, the affected lung is unable to adequately oxygenate the blood, leading to lower oxygen saturations, which are indicative of hypoxemia.
C. Lower energy expenditure
Lower energy expenditure is inappropriate. Energy expenditure is not typically affected by a pneumothorax. While the discomfort and respiratory distress associated with a pneumothorax may cause the individual to limit physical activity, there is no direct impact on overall energy expenditure.
D. Increased lung capacity
Increased lung capacity is inappropriate. A pneumothorax results in partial or complete collapse of the affected lung, reducing lung capacity rather than increasing it. The presence of air in the pleural space creates positive pressure, which can compress the lung and decrease its ability to expand fully during inhalation.

Full Explanation
Choice A Reason:
Higher oxygen saturations of 98% to 99% is inappropriate. A pneumothorax involves the presence of air in the pleural space, which can compromise lung function and gas exchange. This compromised lung function typically leads to decreased oxygenation of the blood, resulting in lower oxygen saturations rather than higher saturations.
Choice B Reason:
Lower oxygen saturations of 93% to 94% is appropriate. A pneumothorax disrupts the normal exchange of oxygen and carbon dioxide in the lungs due to partial or complete lung collapse. As a result, the affected lung is unable to adequately oxygenate the blood, leading to lower oxygen saturations, which are indicative of hypoxemia.
Choice C Reason:
Lower energy expenditure is inappropriate. Energy expenditure is not typically affected by a pneumothorax. While the discomfort and respiratory distress associated with a pneumothorax may cause the individual to limit physical activity, there is no direct impact on overall energy expenditure.
Choice D Reason:
Increased lung capacity is inappropriate. A pneumothorax results in partial or complete collapse of the affected lung, reducing lung capacity rather than increasing it. The presence of air in the pleural space creates positive pressure, which can compress the lung and decrease its ability to expand fully during inhalation.

A nurse is caring for a client in the emergency department who has a preliminary diagnosis of a transient ischemic attack (TIA). Which of the following diagnostic testing should the nurse anticipate the provider to prescribe?
A. Prothrombin time (PT)
Prothrombin time (PT) is a laboratory test that measures the time it takes for blood to clot is incorrect. While PT may be part of a comprehensive evaluation in some cases, it is not typically the initial diagnostic test performed for a TIA. A TIA is caused by a temporary disruption of blood flow to the brain, often due to an embolus or transient blockage in a cerebral artery, rather than a primary disorder of blood clotting.
B. Complete blood count (CBC)
Complete blood count (CBC) is incorrect. A complete blood count (CBC) is a common laboratory test that evaluates the cellular components of the blood, including red blood cells, white blood cells, and platelets. While CBC can provide valuable information about hematological conditions such as anemia or thrombocytosis, it is not specific to diagnosing the cause of a TIA. TIA is primarily a vascular event related to transient ischemia in the brain rather than a disorder of blood cell counts.
C. Computerized tomography angiography (CTA)
Computerized tomography angiography (CTA) is appropriate. CTA is a non-invasive imaging test that combines computed tomography (CT) scanning with contrast dye to visualize blood vessels throughout the body, including those in the brain. CTA can help identify any blockages, narrowing, or abnormalities in the blood vessels supplying the brain, which may be contributing to the TIA. It provides detailed images of the blood vessels' structure and can help guide further management and treatment decisions.
D. Transesophageal echocardiogram (TEE)
Transesophageal echocardiogram (TEE) is inappropriate. Transesophageal echocardiogram (TEE) is an imaging test that provides detailed images of the heart and major blood vessels using sound waves. While TEE may be indicated in some cases of TIA to evaluate for potential cardiac sources of emboli (blood clots), such as atrial fibrillation or cardiac valve abnormalities, it is not typically the first-line diagnostic test performed in the emergency department setting for evaluating a TIA. Initial imaging studies such as CTA or magnetic resonance imaging (MRI) of the brain are usually prioritized to assess for acute changes in cerebral blood flow and potential causes of the TIA.

A nurse is providing care for a client who is at risk of cerebral aneurysm rupture. Which of the following interventions should the nurse include in the care plan?
A. Keep lights turned to medium level in the evening.
Keeping lights turned to medium level in the evening is incorrect. This intervention is aimed at reducing environmental stimuli, which may be appropriate for some patients with neurological conditions to minimize sensory overload and promote rest. However, it is not a specific intervention for preventing cerebral aneurysm rupture.
B. Maintain the head of the bed between 30 and 45°.
Maintaining the head of the bed between 30 and 45° is correct. Keeping the head of the bed elevated can help reduce intracranial pressure and decrease the risk of cerebral aneurysm rupture or rebleeding in patients with aneurysmal subarachnoid hemorrhage. This position promotes venous drainage from the brain and helps prevent increases in intracranial pressure.
C. Administer hypotonic intravenous solutions.
Administering hypotonic intravenous solutions is incorrect. Hypotonic intravenous solutions have a lower osmolarity than blood plasma and can lead to cerebral edema, which may exacerbate intracranial pressure and increase the risk of cerebral aneurysm rupture. Isotonic solutions, such as normal saline (0.9% NaCl) or lactated Ringer's solution, are typically preferred for fluid resuscitation and maintenance in patients at risk of cerebral aneurysm rupture.
D. Reposition the client every shift.
Reposition the client every shift is incorrect. Repositioning the client every shift helps prevent complications associated with immobility, such as pressure ulcers, pneumonia, and venous thromboembolism. While important for overall patient care, repositioning alone does not directly address the risk of cerebral aneurysm rupture.

A nurse is caring for a client who has a transection of the spinal cord at the level of cervical 7. Which of the following assessment findings should the nurse anticipate?
A. The client has no sensation or movement below the level of the injury.
The client has no sensation or movement below the level of the injury is correct. This is a characteristic finding of a complete spinal cord injury, where there is total loss of sensory and motor function below the level of the injury. This pattern is often seen in injuries involving the cervical spinal cord, such as at the level of C7.
B. The client has some movement but no sensation below the level of the injury.
The client has some movement but no sensation below the level of the injury is incorrect. This finding would be more indicative of an incomplete spinal cord injury, where there is partial preservation of sensory or motor function below the level of the injury. However, with a transection of the spinal cord at C7, it is less likely for the client to have retained movement below the level of injury.
C. The client has some movement and also some sensation below the level of the injury.
The client has some movement and also some sensation below the level of the injury is incorrect. This finding is not typically associated with a spinal cord injury at the level of C7. With a transection of the spinal cord at this level, there is typically complete loss of sensory and motor function below the level of the injury.
D. The client has some sensation but no movement below the level of the Injury.
The client has some sensation but no movement below the level of the injury is incorrect. This finding is more consistent with an incomplete spinal cord injury, where there may be partial preservation of sensory function but no motor function below the level of the injury. However, with a transection of the spinal cord at C7, it is less likely for the client to have retained sensation below the level of injury.
