A nurse is caring for a client who has sustained a traumatic brain injury. The nurse should monitor the client for which of the following manifestations of increased intracranial pressure?
Tachypnea
Hypotension
Decreased level of consciousness
Bilateral weakness of extremities
The Correct Answer is C
Choice A: Tachypnea Tachypnea, or rapid breathing, is not typically a direct sign of increased ICP. While it can be associated with various medical conditions, it is not specifically indicative of increased ICP. However, it’s important to note that breathing patterns can change with advanced ICP changes, but these are usually characterized by irregularities rather than just increased rate. Increased intracranial pressure (ICP) is a critical condition that can occur after a traumatic brain injury (TBI). It results from the brain tissue’s response to injury, leading to swelling or bleeding within the skull. The skull is a rigid structure, so any increase in content, such as blood or edema, can lead to an increase in pressure.
Choice B: Hypotension Hypotension, or low blood pressure, is generally not associated with increased ICP. In fact, one of the signs of increased ICP is Cushing’s triad, which includes hypertension (high blood pressure), bradycardia (slow heart rate), and irregular respirations. Therefore, hypotension would not be a typical manifestation of increased ICP.
Choice C: Decreased level of consciousness A decreased level of consciousness is a hallmark sign of increased ICP. As pressure within the skull increases, it can lead to compression of the brain tissue and disruption of cerebral blood flow. This can manifest as changes in alertness, drowsiness, confusion, and in severe cases, loss of consciousness1. when monitoring a client who has sustained a TBI, the nurse should be vigilant for signs of increased ICP, with a decreased level of consciousness being a primary indicator. Other signs may include headache, nausea, vomiting, and changes in pupil size or reactivity. It is crucial to identify and treat increased ICP promptly to prevent further brain injury and potential long-term consequences.
Choice D: Bilateral weakness of extremities While bilateral weakness can be a sign of neurological damage, it is not specific to increased ICP. Increased ICP is more likely to cause global effects on consciousness and brain function rather than isolated weakness in limbs unless there is focal brain injury causing raised ICP.

Correct Answer is A
Explanation
Choice A reason: A distended bladder is a common cause of autonomic dysreflexia. It can trigger an exaggerated response from the autonomic nervous system, leading to a rapid increase in blood pressure. This is because the full bladder sends signals to the spinal cord, which then attempts to send signals to the brain. However, due to the injury, these signals cannot pass through, resulting in a reflex that increases blood pressure.
Choice B reason: While a severe headache is a symptom of autonomic dysreflexia, it is not a cause. The headache results from the body's response to a triggering stimulus, such as a distended bladder, which leads to the high blood pressure characteristic of autonomic dysreflexia.
Choice C reason: Nasal congestion is not typically a cause of autonomic dysreflexia. The condition is usually triggered by a noxious stimulus below the level of the spinal cord injury, such as a full bladder or bowel, skin irritation, or other types of physical discomfort.
Choice D reason: Elevated blood pressure is a symptom, not a cause, of autonomic dysreflexia. The condition itself causes a sudden spike in blood pressure due to an uncontrolled reflex sympathetic discharge in response to a triggering stimulus below the level of the injury.
Correct Answer is C
Explanation
Choice A reason: Myocardial infarction (MI) is not limited to occurrences with exertion. While stable angina typically occurs during physical activity or emotional stress, MI can happen at any time, even at rest. The underlying cause of an MI is the complete blockage of blood supply to a part of the heart muscle, usually due to a blood clot in a coronary artery. This blockage can lead to the death of heart muscle tissue, a condition that requires immediate medical attention.
Choice B reason: Stable angina does not typically last for more than 30 minutes. It is characterized by chest pain or discomfort that occurs predictably with exertion or emotional stress and is relieved within minutes by rest or nitroglycerin. In contrast, the pain from an MI is more prolonged and severe, and it is not relieved by rest or nitroglycerin. If chest discomfort lasts longer than 15 minutes and is not alleviated by rest or nitroglycerin, it is a warning sign that the individual may be experiencing an MI.
Choice C reason: This is the distinguishing feature between stable angina and an MI. Stable angina is usually relieved within 3-5 minutes by rest or nitroglycerin, which helps to dilate the coronary arteries and improve blood flow to the heart muscle. Nitroglycerin is ineffective in relieving the symptoms of an MI because the problem is not just reduced blood flow but a complete blockage that nitroglycerin cannot overcome.
Choice D reason: The pain associated with an MI typically lasts for more than 15 minutes and can be quite severe. Unlike stable angina, the pain of an MI is not relieved by rest or nitroglycerin. The duration and severity of the pain, along with other symptoms such as shortness of breath, sweating, nausea, or lightheadedness, help differentiate an MI from stable angina.
