A nurse is collecting data from a client who has encephalitis due to West Nile virus. Which of the following findings should the nurse expect? (Select all that apply.)

Unilateral weakness

Stiff neck

Photophobia

Epigastric pain

Lethargy

Answer and Explanation

Correct Answer : B,C,E

Choice A reason: Unilateral weakness is an incorrect finding, because it is more indicative of a stroke or a brain tumor than encephalitis. Encephalitis is an inflammation of the brain that can cause neurological symptoms, but they are usually bilateral and symmetrical.

Choice B reason: Stiff neck is a correct finding, because it is a sign of meningeal irritation, which can occur in encephalitis due to the involvement of the meninges (the membranes that cover the brain and spinal cord).

Choice C reason: Photophobia is a correct finding, because it is another sign of meningeal irritation, which can cause sensitivity to light and sound.

Choice D reason: Epigastric pain is an incorrect finding, because it is not related to encephalitis. Epigastric pain is more likely to be caused by a gastrointestinal disorder, such as gastritis or peptic ulcer.

Choice E reason: Lethargy is a correct finding, because it is a sign of altered mental status, which can occur in encephalitis due to the damage to the brain tissue.

Correct Answer is D

Explanation

Choice A reason: This is an incorrect purpose, because raising the bed linens off the client's feet to prevent plantar flexion is not related to the use of an abduction pillow. An abduction pillow is a wedge-shaped pillow that is placed between the client's legs to keep them apart and aligned. Raising the bed linens off the client's feet can be achieved by using a foot cradle or a bed frame.

Choice B reason: This is an incorrect purpose, because keeping the client's heels off the bed to prevent pressure ulcers is not related to the use of an abduction pillow. An abduction pillow is a wedge-shaped pillow that is placed between the client's legs to keep them apart and aligned. Keeping the client's heels off the bed can be achieved by using a heel protector or a pillow under the lower legs.

Choice C reason: This is an incorrect purpose, because positioning the client off the operative site while in bed is not related to the use of an abduction pillow. An abduction pillow is a wedge-shaped pillow that is placed between the client's legs to keep them apart and aligned. Positioning the client off the operative site can be achieved by using a trochanter roll or a pillow under the hip.

Choice D reason: This is the correct purpose, because preventing dislocation of the hip during position changes or movement is the main reason for using an abduction pillow. An abduction pillow is a wedge-shaped pillow that is placed between the client's legs to keep them apart and

A. Respiratory alkalosis B. Metabolic acidosis C. Respiratory acidosis D. Metabolic alkalosis

Correct Answer is A

Explanation

Choice A reason: This is the correct imbalance, because respiratory alkalosis is a condition that occurs when the blood pH is high, the PaCO2 is low, and the HCO3 is normal or low. Respiratory alkalosis is caused by hyperventilation, which can result from anxiety, fever, pain, or mechanical ventilation.

Choice B reason: This is an incorrect imbalance, because metabolic acidosis is a condition that occurs when the blood pH is low, the PaCO2 is normal or low, and the HCO3 is low. Metabolic acidosis is caused by the accumulation of acids in the blood, which can result from diabetic ketoacidosis, renal failure, or lactic acidosis.

Choice C reason: This is an incorrect imbalance, because respiratory acidosis is a condition that occurs when the blood pH is low, the PaCO2 is high, and the HCO3 is normal or high. Respiratory acidosis is caused by hypoventilation, which can result from airway obstruction, chest injury, or narcotic overdose.

Choice D reason: This is an incorrect imbalance, because metabolic alkalosis is a condition that occurs when the blood pH is high, the PaCO2 is normal or high, and the HCO3 is high. Metabolic alkalosis is caused by the loss of acids from the blood, which can result from vomiting, gastric suction, or diuretic therapy.
