The nurse is teaching the client who is scheduled for an outpatient EEG. Which instruction should the nurse include?
- A. Remove all hairpins before coming in for the EEG test.
- B. Avoid eating or drinking at least 6 hours prior to the test.
- C. Some hair will be removed with a razor to place electrodes.
- D. Have blood drawn for a glucose level 2 hours before the test.
Correct Answer: A
Rationale: In an EEG, electrodes are placed on the scalp over multiple areas of the brain to detect and record patterns of electrical activity. Preparation includes clean hair without any objects in the hair to prevent inaccurate test results. The client should not be NPO since a usual glucose level is important for normal brain functioning. The scalp will not be shaved; the electrodes are applied with paste. There is no indication to have a serum glucose drawn before the test.

If the drug is administered every 3 to 4 hours, which nursing action is most appropriate at this time in response to the client's statement?
- A. Administer another dose of the nonopioid analgesic immediately.
- B. Rearrange medication times so that the client receives pain medication hourly.
- C. Consult the physician about ordering an opioid analgesic.
- D. Use a nondrug intervention such as listening to a guided imagery tape.
Correct Answer: D
Rationale: Using a nondrug intervention like guided imagery is appropriate since it's too early for another dose, and it avoids escalating to opioids prematurely.
The client with PD has a new surgically implanted DBS. After the stimulator is operational, which criterion should the nurse use to evaluate that the DBS is effective?
- A. The client has cogwheel rigidity when moving the upper extremities.
- B. The client has a decrease in the frequency and severity of tremors.
- C. The client has less facial pain and converses with more facial expression.
- D. The client no longer experiences auras or a severe frontal headache.
Correct Answer: B
Rationale: Cogwheel rigidity, a symptom of PD, is interrupted muscular movement and is not treated with the DBS. DBS is a treatment used for intractable tremors associated with PD. The electrical current interferes with the brain cells initiating the tremors. Severe facial pain is associated with trigeminal neuralgia, not PD rau. The DBS will not affect facial expression. Auras are unusual sensations experienced before a seizure occurs and are not associated with PD.
The experienced nurse is instructing the new nurse on subarachnoid hemorrhage. The nurse evaluates that the new nurse understands the information when the new nurse makes which statements? Select all that apply.
- A. “Subarachnoid hemorrhage is often associated with a rupture of a cerebral aneurysm.”
- B. “Subarachnoid hemorrhage occurs during sleep and is noticed when the client awakens.”
- C. “The client experiencing a subarachnoid hemorrhage may state having a severe headache.”
- D. “Tissue plasminogen activator (tPA) should be given to treat a subarachnoid hemorrhage.”
- E. “A subarachnoid hemorrhage often results in the cerebrospinal fluid appearing bloody.”
Correct Answer: A,C,E
Rationale: A subarachnoid hemorrhage is usually caused by rupture of a cerebral aneurysm. Ischemic stroke in older adults, not a subarachnoid hemorrhage, often occurs during sleep when circulation and BP decrease. Irritation of the meninges from bleeding into the subarachnoid spaces causes a severe headache. Thrombolytic therapy with tPA lyses clots and is contraindicated in subarachnoid hemorrhage. Bleeding into the subarachnoid space will cause the CSF to be bloody.
Which intervention should the nurse implement when caring for the client diagnosed with encephalitis? Select all that apply.
- A. Turn the client every two (2) hours.
- B. Encourage the client to increase fluids.
- C. Keep the client in the supine position.
- D. Assess for deep vein thrombosis (DVT).
- E. Assess for any alterations in elimination.
Correct Answer: A,D,E
Rationale: Turning every 2 hours (A) prevents pressure ulcers, assessing DVT (D) addresses immobility risks, and monitoring elimination (E) ensures bowel/bladder function. Increased fluids (B) depend on status, and supine positioning (C) may increase ICP.
The nurse is preparing the male client for an electroencephalogram (EEG). Which intervention should the nurse implement?
- A. Explain that this procedure is not painful.
- B. Premedicate the client with a benzodiazepine drug.
- C. Instruct the client to shave all facial hair.
- D. Tell the client it will cause him to see 'floaters.'
Correct Answer: A
Rationale: Explaining that the EEG is painless (A) reduces anxiety. Benzodiazepines (B) are not routine, shaving (C) is unnecessary, and floaters (D) are not associated.
