A nurse teaches a client who is scheduled for a positron emission tomography scan of the brain. Which statement should the nurse include in this client's teaching?
- A. Avoid caffeine-containing substances for 12 hours before the test.
- B. Increase your fluid intake before and after the test.
- C. Do not take your cardiac medication the morning of the test.
- D. Remove your dentures and any metal before the test begins.
Correct Answer: A
Rationale: Caffeine is a central nervous system stimulant that may alter PET scan results, so it should be avoided for 12 hours prior. Increased fluid intake is unnecessary, cardiac medications should be continued, and metal removal is relevant for MRI, not PET.

A nurse prepares to teach a client who has experienced damage to the left temporal lobe of the brain. Which action should the nurse perform when educating this client about newly prescribed medications?
- A. Help the client identify each medication by its color.
- B. Provide written materials with large print size.
- C. Sit on the client's right side and speak into the right ear.
- D. Allow the client to use a white board to ask questions.
Correct Answer: C
Rationale: The temporal lobe contains the auditory center for sound interpretation. The client's hearing will be impaired in the left ear. The nurse should sit on the client's right side and speak into the right ear to compensate for the hearing impairment caused by left temporal lobe damage. The other interventions do not directly address the hearing deficit associated with this condition.
A nurse cares for a client who is experiencing deteriorating neurologic function. The client states, 'I am worried I will not be able to care for my young children.' How should the nurse respond?
- A. Caring for your children is a priority. You may not want to ask for help, but you have to.
- B. Our community has resources that may help you with household tasks so you have energy to care for your children.
- C. You seem distressed. Would you like to talk to a psychologist about adjusting to your changing status?
- D. Give me more information about what worries you, so we can see if we can do something to make adjustments.
Correct Answer: D
Rationale: Exploring the client's specific concerns allows the nurse to tailor interventions and provide appropriate support. The other options make assumptions or suggest solutions without fully understanding the client's needs.
A nurse obtains a focused health history for a client who is scheduled for magnetic resonance angiography. Which priority question should the nurse ask before the test?
- A. Have you had a recent blood transfusion?
- B. Do you have allergies to iodine or shellfish?
- C. Are you taking any cardiac medications?
- D. Do you currently use oral contraceptives?
Correct Answer: B
Rationale: Allergies to iodine or shellfish are critical to assess because the contrast used in magnetic resonance angiography may cause a similar allergic reaction. The other options do not affect the safety or outcome of the procedure.
A nurse plans care for an 83-year-old client who is experiencing age-related sensory perception changes. Which intervention should the nurse include in this client's plan of care?
- A. Provide a call button that requires only light pressure to activate.
- B. Ensure the path to the bathroom is free from equipment.
- C. Encourage the client to season food to stimulate nutritional intake.
- D. Provide written instructions in large print for the client.
Correct Answer: B
Rationale: Clearing the path to the bathroom ensures safe ambulation for a client with sensory perception changes, reducing fall risk. The other options do not directly address the safety concerns related to impaired sensory perception.
A nurse cares for a client who is recovering from a single-photon emission computed tomography (SPECT) with a radiopharmaceutical agent. Which statement should the nurse include when discussing the plan of care with this client?

- B. You are radioactive and must use a private bathroom.
- C. Frequent assessments of the injection site will be completed.
- D. We will be monitoring your renal function closely.
Correct Answer: A
Rationale: No special precautions are needed after SPECT, as radioisotopes are eliminated in urine without requiring monitoring or activity restrictions. The other options are unnecessary.
