A nurse is evaluating the central venous pressure (CVP) of a client who has sustained multiple traumas. Which of the following interpretations of a low CVP should the nurse make?
Fluid overload
Intracardiac shunt
Hypovolemia
Left ventricular failure
The Correct Answer is C
Choice A Reason: This is incorrect because fluid overload is a condition of excess fluid volume in the body. A client who has fluid overload is more likely to have a high CVP, which indicates increased pressure in the right atrium and vena cava.
Choice B Reason: This is incorrect because an intracardiac shunt is a condition of abnormal blood flow between the chambers of the heart. A client who has an intracardiac shunt may have a normal or high CVP, depending on the direction and magnitude of the shunt.
Choice C Reason: This is correct because hypovolemia is a condition of low fluid volume in the body. A client who has hypovolemia is more likely to have a low CVP, which indicates decreased pressure in the right atrium and vena cava.
Choice D Reason: This is incorrect because left ventricular failure is a condition of impaired pumping function of the left ventricle. A client who has left ventricular failure may have a normal or high CVP, depending on the degree of backward failure and pulmonary congestion.

Correct Answer is B
Explanation
Choice A: Drainage of clear fluid from the ears is not an expected finding for a client who has an epidural hematoma, but rather a sign of a basilar skull fracture, which is a different type of head injury. The clear fluid is cerebrospinal fluid (CSF), which leaks from the brain through the fractured skull.
Choice B: Alternating periods of alertness and unconsciousness is an expected finding for a client who has an epidural hematoma, because it indicates a rapid increase in intracranial pressure (ICP) due to bleeding between the dura mater and the skull. The client may have a brief loss of consciousness at the time of injury, followed by a lucid interval, and then a rapid deterioration of mental status.
Choice C: Narrowing pulse pressure is not an expected finding for a client who has an epidural hematoma, but rather a sign of increased ICP due to any cause. Pulse pressure is the difference between systolic and diastolic blood pressure. As ICP rises, it compresses the brainstem and causes bradycardia and hypertension, resulting in a decreased pulse pressure.
Choice D: Extensive bruising in the mastoid area is not an expected finding for a client who has an epidural hematoma, but rather a sign of a basilar skull fracture, which is a different type of head injury. The bruising is also known as Batle's sign, and it occurs due to blood pooling behind the ear.
Correct Answer is B
Explanation
Choice A Reason: This choice is incorrect because urinary hesitancy is not the priority finding for the nurse to address.
Urinary hesitancy is a difficulty or delay in starting or maintaining a urine stream. It may be caused by various factors such as prostate enlargement, urinary tract infection, medication side effects, or psychological issues. It may cause discomfort, pain, or urinary retention, but it does not pose an immediate threat to the client's life.
ChoiceB Reason: This choice is correct because dysphagia is the priority finding for the nurse to address. Dysphagia is a difficulty or inability to swallow food or liquids. It may be caused by various factors such as stroke, Parkinson's disease, dementia, esophageal cancer, or oral infections. It may cause malnutrition, dehydration, aspiration, or choking, which can lead to serious complications such as pneumonia, sepsis, or death. Therefore, the nurse should assess the client's swallowing function and provide appropriate interventions such as modifying the diet texture, using thickening agents, or teaching swallowing techniques.
ChoiceC Reason: This choice is incorrect because swollen gums are not the priority finding for the nurse to address. Swollen gums are an inflammation or enlargement of the gingival tissue that surrounds the teeth. They may be caused by various factors such as poor oral hygiene, gum disease, vitamin deficiency, medication side effects, or hormonal changes. They may cause bleeding, pain, or infection, but they do not pose an immediate threat to the client's life.
Choice D Reason: This choice is incorrect because pruritus is not the priority finding for the nurse to address. Pruritus is a sensation of itching that affects the skin. It may be caused by various factors such as dry skin, allergies, eczema, psoriasis, liver disease, or kidney disease. It may cause discomfort, scratching, or skin damage, but it does not pose an immediate threat to the client's life.
