A nurse is planning care for several clients and is considering the clients' risk for stroke. Which of the following conditions places the client at risk for an ischemic embolic stroke?

A client who has an arteriovenous malformation

A client who has thrombocytopenia

A client who has chronic atrial fibrillation

A client who has uncontrolled hypertension

Answer and Explanation

The Correct Answer is C

A client who has chronic atrial fibrillation is at risk for an ischemic embolic stroke. An ischemic embolic stroke occurs when a blood clot that forms in one part of the body travels to the brain and blocks blood ﬂow. Atrial fibrillation is a type of irregular heart rhythm that can cause blood to pool, thicken, and clot in the heart or arteries near it. Pieces of these clots can travel to the brain and cause an ischemic embolic stroke.

a. A client who has an arteriovenous malformation is not at risk for an ischemic embolic stroke.
b. A client who has thrombocytopenia is not at risk for an ischemic embolic stroke.
d. A client who has uncontrolled hypertension is at risk for a stroke but not specifically an ischemic embolic
stroke.

Correct Answer is D

Explanation

The nurse should immediately report small drops of clear ﬂuid in the left ear to the charge nurse. This finding could indicate a cerebrospinal ﬂuid (CSF) leak, which can occur as a result of a head injury. A CSF leak can be a serious medical condition that requires immediate attention.

An edematous bruise on the forehead, client disorientation to place, and a heart rate of 110/min and regular are also important findings that the nurse should report to the charge nurse. However, these findings are not as urgent as the presence of small drops of clear ﬂuid in the left ear.

A. Nuchal rigidity B. Batle's sign C. Polyuria D. Lethargy

Correct Answer is D

Explanation

The nurse should monitor the client for lethargy as a manifestation of increased intracranial pressure. Increased intracranial pressure (ICP) is a rise in pressure around the brain that can occur due to various reasons such as brain injury, bleeding into the brain, swelling in the brain, or an increase in cerebrospinal ﬂuid. Lethargy (feeling less alert than usual) is a common symptom of increased ICP.

a. Nuchal rigidity is not a common symptom of increased ICP.
b. Batle's sign is not a common symptom of increased ICP.
c. Polyuria is not a common symptom of increased ICP.
