The nurse is caring for a client who is undergoing single-photon emission computed tomography (SPECT). What is a potential side effect that this client may suffer?
- A. Headache and pain in the neck
- B. Claustrophobia
- C. Allergic reaction to the imaging material
- D. Allergic reaction to radioactive rays
Correct Answer: C
Rationale: SPECT obtains images of the brain after the client intravenously receives radiopharmaceuticals and radioisotopes approximately 1 hour before the test begins. A potential risk of SPECT is the client's allergic reaction to the imaging material. Headache is an aftereffect of a cisternal puncture, and claustrophobia is experienced by clients during a magnetic resonance imaging scan.

A client undergoes a scheduled electroencephalogram (EEG). Which post-procedure activity is most appropriate?
- A. Measure the heart and the pulse rate.
- B. Provide the client with caffeine-rich drinks.
- C. Allow the client to wash hair and rest.
- D. Measure the level of consciousness (LOC) of the client.
Correct Answer: C
Rationale: After an EEG, the nurse should ensure rest for the sleep-deprived client and allow the client to wash hair to remove the glue used to affix electrodes to the scalp. The client is advised not to take sedative drugs and caffeine-related drinks before the EEG; therefore, there is no reason to provide the client with them after the test. The nurse should not measure the LOC, the heart rate, or the pulse rate of the client unless advised by the health care provider.
A nurse is noting from a client's neurologic assessment findings that the client's motor impulses are interrupted from the brain to the spinal cord. It also appears that the client lacks sensory impulses from the peripheral sensory neurons to the brain. Which area has the deficit?
- A. Midbrain
- B. Medulla oblongata
- C. Pons
- D. Subarachnoid space
Correct Answer: B
Rationale: The medulla oblongata lies below the pons and transmits motor impulses from the brain to the spinal cord, and sensory impulses from the peripheral sensory neurons to the brain. The pons is part of the brainstem. The midbrain forms the forward part of the brainstem and connects the pons and the cerebellum with the two cerebral hemispheres. The subarachnoid space lies between the pie matter and the arachnoids membrane.
A client is waiting in a triage area to learn the medical status of family members following a motor vehicle accident. The client is pacing, taking deep breaths, and handwringing. Considering the effects in the body systems, what does the nurse anticipate the liver will do?
- A. Cease function and shunt blood to the heart and lungs.
- B. Convert glycogen to glucose for immediate use.
- C. Produce a toxic by-product in relation to stress.
- D. Maintain a basal rate of functioning.
Correct Answer: B
Rationale: When the body is under stress, the sympathetic nervous system is activated to ready the body for action. The effect of the body is to mobilize stored glycogen to glucose to provide additional energy for body action.
The nurse is assessing the client's pupils following a sports injury. Which assessment finding(s) indicates a neurologic concern? Select all that apply.
- A. Unequal pupils
- B. Pupil reaction quick
- C. Pinpoint pupils
- D. Absence of pupillary response
- E. Pupil reacts to light
Correct Answer: A,C,D
Rationale: Normal assessment findings include the pupils being equal and reactive to light. Pupils that are unequal, pinpoint in nature, or fail to respond indicate a neurologic impairment.
A nurse is caring for a client with an injury to the central nervous system. When caring for a client with a spinal cord insult that is slowing transmission of the motor neurons, in what would the nurse anticipate a delayed reaction?
- A. Identification of information due to slowed passages of information to brain.
- B. Cognitive ability to understand relayed information.
- C. Processing information transferred from the environment.
- D. Response due to interrupted impulses from the central nervous system
Correct Answer: D
Rationale: The central nervous system is composed of the brain and the spinal cord. Motor neurons transmit impulses from the central nervous system. Slowing transmission in this area would slow the response of transmission leading to a delay in reaction. Sensory neurons transmit impulses from the environment to the central nervous system, allowing identification of a stimulus. Cognitive centers of the brain interpret the information.
