A patient experiencing fluctuating levels of awareness, confusion, and disturbed orientation shouts, 'Bugs are crawling on my legs! Get them off!' Which problem is the patient experiencing?
- A. Aphasia
- B. Dystonia
- C. Tactile hallucinations
- D. Mnemonic disturbance
Correct Answer: C
Rationale: The patient feels bugs crawling on both legs, although no sensory stimulus is actually present. This description coincides with the definition of a hallucination, a false sensory perception. Tactile hallucinations may be part of the symptom constellation of delirium. Aphasia refers to a speech disorder. Dystonia refers to excessive muscle tonus. Mnemonic disturbance is associated with dementia rather than delirium.

A patient has progressive memory deficit associated with dementia. Which nursing intervention would best help the individual function in the environment?
- A. Assist the patient to perform simple tasks by giving step-by-step directions.
- B. Reduce frustration by performing activities of daily living for the patient.
- C. Stimulate intellectual function by discussing new topics with the patient.
- D. Promote the use of the patient's sense of humor by telling jokes.
Correct Answer: A
Rationale: Patients with a cognitive impairment should perform all tasks of which they are capable. When simple directions are given in a systematic fashion, the patient is better able to process information and perform simple tasks. Stimulating intellectual functioning by discussing new topics is likely to prove frustrating for the patient. Patients with cognitive deficits may lose their sense of humor and find jokes meaningless.

What is the priority nursing intervention for a patient diagnosed with delirium who has fluctuating levels of consciousness, disturbed orientation, and perceptual alterations?
- A. Avoidance of physical contact
- B. High level of sensory stimulation
- C. Careful observation and supervision
- D. Application of wrist and ankle restraints
Correct Answer: C
Rationale: Careful observation and supervision are of ultimate importance because an appropriate outcome would be that the patient remains safe and free from injury. Physical contact during care cannot be avoided. Restraint is a last resort, and sensory stimulation should be reduced.
A patient diagnosed with moderate to severe Alzheimer's disease has a dressing and grooming self-care deficit. The nurse notes that the patient is wearing mismatched clothing and has poor personal hygiene. Which interventions should be included in the patient's plan of care?
- A. Provide clothing with elastic and hook-and-loop closures.
- B. Label clothing with the patient's name and name of the item.
- C. Administer antianxiety medication before bathing and dressing.
- D. Provide necessary items and direct the patient to proceed independently.
- E. If the patient resists, use distraction and then try again after a short interval.
Correct Answer: A,B,E
Rationale: Providing clothing with elastic and hook-and-loop closures facilitates patient independence. Labeling clothing with the patient's name and the name of the item maintains patient identity and dignity (and provides information if the patient has agnosia). When a patient resists, using distraction and trying again after a short interval are appropriate because patient moods are often labile; the patient may be willing to cooperate during a later opportunity. Providing the necessary items for grooming and directing the patient to proceed independently are inappropriate. Staff members are prepared to coach by giving step-by-step directions for each task as it occurs. Administering anxiolytic medication before bathing and dressing is inappropriate. This measure would result in unnecessary overmedication.
