Extract:
Question 1 of 5
The nurse is caring for the client who had a stroke affecting the right hemisphere of the brain. The nurse should assess for which problem initially?
Correct Answer: C
Rationale: A stroke affecting the right hemisphere may produce left, not right hemiparesis. Motor fibers in the brain cross over in the medulla before entering the spinal column. This client may or may not have aphasia because the center for language is located on the left side of the brain in 75% to 80% of the population; this client had a stroke involving the right hemisphere. Even though the client may have expressive aphasia, it is more important to assess for poor impulse control due to the risk for injury. The client with a stroke affecting the right side of the brain often exhibits impulsive behavior and is unaware of the neurological deficits. Poor impulse control increases the client’s risk for injury. Tetraplegia (quadriplegia) is associated with an SCI; tetraplegia usually does not occur from a stroke.
Question 2 of 5
The nurse is caring for the client who has limited intake due to dysphagia following an ischemic stroke. Which serum laboratory result should the nurse review to verify that the client is dehydrated?
Correct Answer: B
Rationale: The serum creatinine is elevated with renal insufficiency or renal failure. The BUN is elevated when the client is dehydrated due to the lack of fluid volume to excrete waste products. The Hgb is decreased with blood loss or anemia from nutritional deficiencies, not with dehydration. A decreased prealbumin indicates a nutritional deficiency.
Question 3 of 5
Which behavior is a risk factor for developing and spreading bacterial meningitis?
Correct Answer: A
Rationale: URI (
A) increases the risk of bacterial meningitis by facilitating bacterial invasion. Sexual intercourse (
B), alcohol (
C), and tobacco (
D) are not direct risk factors.
Question 4 of 5
Which intervention should the nurse take with the client recently diagnosed with amyotrophic lateral sclerosis (Lou Gehrig's disease)?
Correct Answer: C
Rationale: ALS is progressive and terminal. Providing an advance directive (
C) ensures the client’s wishes are respected early. Gastrostomy (
A) is later, fistulas (
B) are unrelated, and leg braces (
D) are less urgent.
Question 5 of 5
Which assessment data would indicate to the nurse that the client would be at risk for a hemorrhagic stroke?
Correct Answer: C
Rationale: Severe hypertension (BP 220/120 mm Hg,
C) is a major risk factor for hemorrhagic stroke due to vessel rupture. High blood glucose (
A) is more linked to ischemic stroke, a carotid bruit (
B) indicates atherosclerosis, and bronchogenic carcinoma (
D) is unrelated.
