ANS: B Agnosia is a total or partial loss of the ability to recognize familiar objects or people through sensory stimuli as a result of organic brain damage.

23. An 83-year-old patient has had a stroke. He is right-handed and has a history of hypertension and "little" strokes. He presents with right hemiplegia. To afford him the best visual field, the nurse should approach him a. from the right side. b. from the left side. c. from the center. d. from either side.

ANS: B Another perceptual problem is hemianopia, which is characterized by defective vision or blindness in half of the visual field. If the patient has hemianopia, which is common, the patient should be approached from the nonparalyzed side for care.

18. A patient, age 52, is brought to the emergency department by ambulance after she hit her head on her bathroom sink and fell unconscious to the floor. Which assessment should the nurse perform first? a. History of health problems b. Patency of airway c. Neurological status d. Status of bodily functions

ANS: B Nursing diagnosis and interventions for the patient with a severe head injury may include Ineffective breathing pattern related to neuromuscular impairment. Nursing interventions will be to maintain a patent airway.

28. In the aging process, older adults are able to a. react to events immediately. b. master new material quickly. c. remember information from the immediate present (short-term memory). d. learn new skills.

ANS: D Most older people possess the ability to learn, but the speed of learning is slowed. Short-term memory is more affected by aging than is long-term memory.

11. A patient has a history of tonic-clonic seizures. She was admitted to the neurological unit after having had three tonic-clonic seizures in the past 2 days. Her husband reported that she had been sleeping for long periods after each seizure. The nurse explains to him that this rest period after a tonic-clonic seizure is called a a. convalescent period. b. post-status epilepticus period. c. post-tonic-clonic period. d. postictal period.

ANS: D Seizures are followed by a rest period of variable length, called a postictal period.

During planning, the nurse remembers this is a degenerative neurological disease that a. occurs most often in tropical climates. b. occurs most often in the older adult. c. has classic signs and symptoms that are readily recognized. d. results from demyelination of the nerve sheath.

ANS: D In patients with multiple sclerosis, multiple foci of demyelination are distributed randomly in the white matter of the brain stem, spinal cord, optic nerves, and cerebrum.

21. When planning care for a patient with aphasia, the nurse should a. talk loudly so he or she can hear. b. refrain from giving explanations about procedures because the patient cannot understand them anyway. c. provide as much environmental stimuli as possible to prevent feelings of isolation. d. consider the type of aphasia that the patient has and adapt communication methods accordingly.

ANS: D Many stroke patients have communication problems, including dysarthria and aphasia. The nurse should wait for the patient to communicate, rather than prompting or finishing the sentence before the patient has a chance to find the appropriate word.

13. A patient has been complaining of headaches. If the headaches are migraine, the nurse would expect to assess that the headaches: a. They are observed during times of stress. b. They become worse toward evening. c. They have their onset when the person is in his or her twenties or thirties. d. They may cause unusual smells or sounds for the patient before the pain begins.

ANS: D Migraine headaches are unusual in that there are prodromal (early signs and symptoms of a developing condition or disease) signs and symptoms that occur before the acute attack.

1. The name of this area of the brain means "bridge." It is the origin of cranial nerves V through VIII and is responsible for sending impulses to the structures inferior and superior to it. It also contains a respiratory center that complements the part of the brain stem located inferior to it. It is called the a. medulla oblongata. b. diencephalon. c. cerebellum. d. pons.

ANS: D The pons connects the midbrain to the medulla oblongata. The word pons means "bridge." It is the origin of cranial nerves V and VIII.
