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.

When doing an admission assessment for a patient, the nurse notices that the patient pauses before answering questions about the health history. Which action by the nurse is most appropriate?
- A. Interview a family member instead.
- B. Wait for the patient to answer the questions.
- C. Remind the patient that you have other patients who need care.
- D. Give the patient an assessment form listing the questions and a pen.
Correct Answer: B
Rationale: When a patient pauses before answering questions about their health history, it is important for the nurse to be patient and wait for the patient to answer the questions. Patients from different cultures may take time to consider a question carefully before responding. By waiting patiently, the nurse shows respect for the patient's pace and helps foster a trusting relationship. Asking a family member to answer instead may not provide accurate information from the patient themselves. Reminding the patient about other patients needing care could make the patient feel rushed or unimportant. Giving the patient an assessment form and pen does not address the underlying reason for the pause and may come across as dismissive of the patient's need for time to respond thoughtfully.
What is a priority goal of involuntary hospitalization of the severely mentally ill client?
- A. Re-orientation to reality
- B. Elimination of symptoms
- C. Protection from harm to self or others
- D. Return to independent functioning
Correct Answer: C
Rationale: The priority goal of involuntary hospitalization of severely mentally ill clients is to ensure protection from harm to self or others. Involuntary hospitalization is often necessary for individuals who are deemed dangerous to themselves or others or who are considered gravely disabled. Re-orientation to reality, elimination of symptoms, and return to independent functioning are important aspects of mental health care but are not the primary goals of involuntary hospitalization. The main focus during involuntary hospitalization is to address safety concerns and prevent harm.
Which behavior best indicates that the client has received adequate preparation for the scheduled diagnostic studies?
- A. Asks for the tests to be explained again
- B. Checks the appointment card multiple times
- C. Arrives early and waits quietly to be called for the tests
- D. Paces back and forth in the hallway on the morning of the tests
Correct Answer: C
Rationale: The correct answer is arriving early and waiting quietly to be called for the tests. This behavior indicates that the client is prepared, as early arrival suggests an expected degree of anxiety and the quiet waiting indicates a lower level of anxiety and adequate preparation. Asking for the tests to be explained again may signal inadequate explanation, nervousness, or poor memory. Checking the appointment card repeatedly or pacing up and down the hallway indicate a high level of anxiety, which could be associated with inadequate teaching. Nurses providing preprocedural teaching should assess for anxiety related to procedures, coping mechanisms, and retention of information post-teaching. If issues are identified, strategies such as paraphrasing information, having a support person present, seeking advice from someone who has undergone the procedure, or visiting the test center beforehand can be utilized.
What psychodynamic process is suggested by a client calling the emergency department during a suicide attempt?
- A. A cry for help
- B. A need for attention
- C. Ambivalence about dying
- D. An inability to stick to a decision
Correct Answer: C
Rationale: The correct answer is 'Ambivalence about dying.' When a client calls the emergency department during a suicide attempt, it suggests conflicting feelings about living and dying. This act can indicate an unconscious desire to be stopped from dying, showing ambivalence between the wish to die and the wish to live. It is not primarily a cry for attention or a need to punish others. The client's intention of suicide alongside seeking help demonstrates the struggle between life and death, making ambivalence the key psychodynamic process at play.
The nurse is performing an admission assessment for a non-English speaking patient who is from China. Which actions could the nurse take to enhance communication (select one that does not apply)?
- A. Use an electronic translation application.
- B. Use a telephone-based medical interpreter.
- C. Wait until an agency interpreter is available.
- D. Ask the patient's teenage daughter to interpret.
Correct Answer: D
Rationale: Electronic translation applications, telephone-based medical interpreters, and agency interpreters are all appropriate tools to enhance communication with non-English-speaking patients. However, asking the patient's teenage daughter to interpret is not recommended due to potential misinterpretation of crucial information during the admission assessment. While family members may be considered in the absence of a professional interpreter, there is a risk of misunderstanding or lack of sharing essential details. It is important to rely on trained interpreters to ensure accurate communication and avoid miscommunication or misinterpretation of critical information. Using gestures can be helpful, but over-exaggeration of gestures is unnecessary and may lead to confusion.
