Which statement best describes the pathophysiology of dementia of the Alzheimer type?
- A. There is a genetic predisposition and dysregulation of neurotransmitters.
- B. The dementia is transient and secondary to a physical imbalance or disorder.
- C. Hypoxia and decreased perfusion of select areas of the brain cause tissue damage.
- D. The presence of amyloid plaques is associated with brain tissue destruction.
Correct Answer: D
Rationale: In Alzheimer's disease, the accumulation of amyloid plaques in the brain is a hallmark feature. These plaques are associated with the destruction of brain tissue, contributing to the cognitive decline seen in dementia. Genetic predisposition and dysregulation of neurotransmitters are factors linked to the development of Alzheimer's disease, but the primary pathology lies in the amyloid plaques. Transient dementia is not characteristic of Alzheimer's disease, which is a progressive neurodegenerative disorder. Hypoxia and decreased perfusion are more typical of vascular dementia, where blood flow to the brain is compromised.

Which characteristic usually results in a behavior being viewed and accepted as normal?
- A. Fits within standards accepted by one's society
- B. Helps the person reduce the need for coping skills
- C. Allows the person to express feelings and thoughts
- D. Facilitates achievement of short-term and long-term goals
Correct Answer: A
Rationale: Behaviors that align with the standards accepted by a society are generally viewed as normal. Societal norms and values play a significant role in defining what is considered normal behavior. Choices B, C, and D may be important aspects of an individual's functioning, but they do not solely determine whether a behavior is viewed as normal. Coping skills, expressions of feelings, and goal achievement can vary in their cultural context and societal acceptance, therefore they are not definitive indicators of normalcy.
The nurse develops a goal that makes a client feel as if they are engaging in a competition. Which type of motivation is the nurse using in this situation?
- A. Power motivation
- B. Affiliative motivation
- C. Avoidance motivation
- D. Achievement motivation
Correct Answer: A
Rationale: The nurse is using power motivation in this situation. Power-motivated individuals tend to have assertive and aggressive behavior. By designing goals that make clients feel like they are in a competition, the nurse appeals to their need for power and accomplishment, even when they are competing against themselves. Affiliative motivation is characterized by nonassertive behavior and dependence on others, which is not applicable here. Avoidance motivation focuses on anxiety, fear of failure, and phobias, which are not relevant to the scenario. Achievement motivation does not involve aggressive behavior or the need for competition, making it an incorrect choice for this scenario.
After a mastectomy or a hysterectomy, a client may feel incomplete as a woman. Which statement would alert the nurse to this feeling in a client who has undergone a total hysterectomy?
- A. "I don't know who can help me during my recovery."
- B. "I feel washed out; there isn't much left."
- C. "I'm scared about the pain in recovery."
- D. "I can't wait to get home; I so want to see my grandchild."
Correct Answer: B
Rationale: The correct answer is "I feel washed out; there isn't much left." This statement suggests a feeling of emptiness or incompleteness after the surgical procedure. Concern about who can assist during recovery, fear of pain, or excitement to go home and see a grandchild are not indicative of feeling incomplete as a woman after a hysterectomy. These other statements focus on practical concerns, physical discomfort, and positive emotions, respectively.
The parents tell the nurse that their preschooler often awakes from sleep screaming in the middle of the night. The preschooler is not easily comforted and screams if the parents try to restrain the child. What should the nurse instruct the parents to do?
- A. Always read a story to the child before bedtime.
- B. Intervene only if necessary to protect the child from injury.
- C. Discuss counseling options with the primary health care provider.
- D. Try to wake the child and ask the child to describe the dream.
Correct Answer: B
Rationale: Waking up screaming from sleep at night indicates sleep terrors. The nurse would advise the parents to observe the child and intervene only if there is a risk for injury. Reading a story before bedtime helps calm the child before sleeping, but it does not ensure that the child will not have a sleep terror. There is no need for professional counseling because sleep terrors are a common phenomenon in preschool-age children. Trying to wake the child and asking the child to describe the dream is not appropriate as the child is not aware of anybody's presence during a sleep terror, and this may cause the child to scream and thrash more.
The family of a child with cerebral palsy (CP) is at risk for difficult parenting issues. Which basis would the nurse conclude as the probable cause for this difficulty?
- A. Lack of social support
- B. Unrealistic expectations
- C. Loss of the expected healthy child
- D. Having a child with cognitive impairment
Correct Answer: C
Rationale: The correct answer is 'Loss of the expected healthy child.' Parents of a child with cerebral palsy often grieve the loss of the healthy child they expected, mourning what could have been and what may never be. While lack of social support can contribute to parenting difficulties, it is not the primary basis in this case. Unrealistic expectations may play a role for some parents, but not all. Additionally, it is important to note that not all children with cerebral palsy experience cognitive impairment; around 30% to 50% of children with cerebral palsy have cognitive challenges.
