A nurse is educating a group of nursing students about brain herniation.
Which of the following interventions should the nurse include as a potential treatment for brain herniation?
Hyperventilate the patient.
Decrease sedation.
Reduce the temperature in the room.
Lower blood pressure.
The Correct Answer is A
Choice A rationale
Hyperventilation is a potential treatment for brain herniation. Hyperventilation causes a decrease in carbon dioxide levels in the blood, leading to vasoconstriction of the cerebral blood vessels. This reduces cerebral blood flow and decreases intracranial pressure, which can help in the management of brain herniation.
Choice B rationale
Decreasing sedation is not typically a treatment for brain herniation. Sedation can be used in the management of increased intracranial pressure, but it is not a direct treatment for brain herniation.
Choice C rationale
Reducing the temperature in the room is not a direct treatment for brain herniation. While temperature control is important in the overall management of a patient with brain injury, it does not directly treat brain herniation.
Choice D rationale
Lowering blood pressure is not a direct treatment for brain herniation. While maintaining optimal blood pressure is important in the management of brain injury, aggressive lowering of blood pressure is not typically done as it could compromise cerebral perfusion.

Correct Answer is C
Explanation
Choice A rationale
Lifting a patient under the shoulders by two nurses can be strenuous and may not provide adequate support for a patient who can only partially assist.
Choice B rationale
While this method may work for some patients, it relies heavily on the patient’s strength and ability to push with their feet. If the patient is weak or unable to exert enough force, this method could be unsafe.
Choice C rationale
Using a device to reduce friction is the most appropriate technique when shifting a patient who can only partially assist. Devices such as slide sheets or transfer boards can help move the patient smoothly and with less physical strain on the healthcare provider.
Choice D rationale
Lifting the patient’s legs while the patient uses a trapeze bar requires significant upper body strength from the patient and may not be feasible for all patients.
Correct Answer is B
Explanation
Choice A rationale
Phosphate levels are not directly affected by spironolactone. Spironolactone is a potassium- sparing diuretic and does not typically affect phosphate levels.
Choice B rationale
Decreased potassium level is not typically expected in a patient taking spironolactone. Spironolactone is a potassium-sparing diuretic, meaning it can actually lead to increased potassium levels. However, in the context of liver failure and ascites, other factors may influence potassium levels.
Choice C rationale
Chloride levels are not directly affected by spironolactone. Spironolactone primarily affects the balance of potassium and sodium in the body.
Choice D rationale
Sodium levels could potentially be decreased in a patient taking spironolactone, as it can cause the body to lose sodium. However, in the context of liver failure and ascites, sodium levels are often carefully managed.
