An acute care nurse receives a shift report for a client who has increased intracranial pressure. The nurse is told that the client demonstrates decorticate posturing. Which of the following findings should the nurse expect to observe when assessing the client?
Pronation of the hands.
Extension of the arms.
External rotation of the lower extremities.
Plantar flexion of the legs.
The Correct Answer is D
Choice A Reason:
Pronation of the hands.
Pronation of the hands is not typically associated with decorticate posturing. Decorticate posturing is characterized by the flexion of the arms and wrists, with the hands often clenched into fists. Pronation refers to the rotation of the hands so that the palms face downward, which is not a feature of decorticate posturing.
Choice B Reason:
Extension of the arms.
Extension of the arms is more characteristic of decerebrate posturing, not decorticate posturing. In decorticate posturing, the arms are flexed and held tightly to the chest, not extended. This flexion is due to damage to the cerebral hemispheres, which affects the corticospinal tract.
Choice C Reason:
External rotation of the lower extremities.
External rotation of the lower extremities is not a typical finding in decorticate posturing. In decorticate posturing, the legs are usually extended and rigid, with the toes pointed. External rotation would indicate a different type of posturing or neurological condition.
Choice D Reason:
Plantar flexion of the legs.
Plantar flexion of the legs is a characteristic finding in decorticate posturing. This involves the toes pointing downward, which is a result of the increased muscle tone and reflexes due to the brain injury. This posture indicates severe damage to the brain, specifically the corticospinal tract.

Correct Answer is ["B","C","E"]
Explanation
Choice A: Lean on your back with your knees bent.
Reason: This instruction is incorrect. Pursed lip breathing is typically performed in a seated position with the neck and shoulders relaxed. Lying on your back with knees bent is not a recommended position for this breathing technique.
Choice B: Use your abdominal muscles to squeeze air out of your lungs.
Reason: This instruction is correct. Using the abdominal muscles helps to expel air more effectively from the lungs, which is a key component of pursed lip breathing. This technique helps to improve ventilation and reduce the work of breathing.

Choice C: Breathe out slowly without puffing your cheeks.
Reason: This instruction is correct. Breathing out slowly through pursed lips without puffing the cheeks helps to keep the airways open longer, allowing more air to be expelled from the lungs. This technique is particularly beneficial for individuals with chronic obstructive pulmonary disease (COPD) or other respiratory conditions.
Choice D: Focus on inhaling and holding your breath as long as you can.
Reason: This instruction is incorrect. The focus of pursed lip breathing is on controlled exhalation rather than holding the breath. Inhaling should be done slowly through the nose, and exhaling should be prolonged through pursed lips.
Choice E: Exhale at least twice the amount of time it took to breathe in.
Reason: This instruction is correct. The exhalation phase should be longer than the inhalation phase, typically taking at least twice as long. This helps to improve the efficiency of breathing and reduce shortness of breath.
Choice F: Open your mouth and breathe deeply.
Reason: This instruction is incorrect. Pursed lip breathing involves breathing in through the nose and exhaling through pursed lips. Opening the mouth and breathing deeply is not part of this technique.
Correct Answer is D
Explanation
Choice A Reason:
Assess the client’s oxygen saturation and, if normal, turn off the oxygen. This option is not ideal because turning off the oxygen completely can lead to a rapid drop in oxygen saturation levels, especially in patients who require continuous oxygen therapy. Monitoring oxygen saturation is crucial, but turning off the oxygen is not recommended unless specifically advised by a healthcare provider. Normal oxygen saturation levels typically range from 95% to 100%1. If the levels drop below 90%, it can lead to hypoxemia, which can cause serious complications.
Choice B Reason:
Have the client lift the mask off the face when taking bites of food. This option is also not ideal because it can be cumbersome for the client and may lead to inconsistent oxygen delivery. The Venturi mask is designed to provide a precise concentration of oxygen, and lifting it off repeatedly can disrupt this consistency. Additionally, it can be uncomfortable and impractical for the client to manage the mask while eating.
Choice C Reason:
Turn the oxygen off while the client eats the meal and then restart it. This option is not recommended for similar reasons as Choice A. Turning off the oxygen can lead to a significant drop in oxygen saturation levels, which can be dangerous for the client. Continuous oxygen therapy is essential for maintaining adequate oxygen levels in patients who require it. Interrupting this therapy, even temporarily, can have adverse effects on the client’s health.
Choice D Reason:
Determine if the client can switch to a nasal cannula during the meal. This is the best option because a nasal cannula allows the client to receive continuous oxygen while eating. The nasal cannula is less obtrusive and more comfortable for the client, enabling them to eat without significant interruption to their oxygen therapy. Nasal cannulas are commonly used for patients who need supplemental oxygen but also need to perform activities such as eating and talking. This approach ensures that the client maintains adequate oxygen levels while having their meal.
