The wife of a patient diagnosed with paranoid schizophrenia asks: “I’ve been told that my husband’s illness is probably related to imbalanced brain chemicals. Can you be more specific?”

Correct Answer: C

Rationale: The correct answer is C: An increase in the brain chemical dopamine explains the presence of delusions and hallucinations. In paranoid schizophrenia, there is an overactivity of dopamine receptors in the brain, leading to an excess of dopamine. This excess dopamine is associated with symptoms like delusions and hallucinations. Therefore, an increase in dopamine levels is directly linked to these specific symptoms in individuals with paranoid schizophrenia. Explanation for why the other choices are incorrect: A: Breakdown of dopamine producing LSD does not directly relate to the symptoms of paranoid schizophrenia. B: Decreased amounts of dopamine do not explain the presence of delusions and hallucinations in paranoid schizophrenia; it is the increase in dopamine that is associated with these symptoms. D: An increase in dopamine is more closely related to delusions and hallucinations rather than lack of motivation and disordered affect in paranoid schizophrenia.

Correct Answer: D

Rationale: The correct answer is D: Losing control over her emotions. The teen's statement indicates a fear of losing control if she starts crying. This fear suggests that she believes crying will lead to an inability to stop, indicating a concern about managing her emotions. This fear of losing control over her emotions aligns with the teen's hesitance to express her grief through tears. A: Appearing emotionally immature - This choice is incorrect as the teen's statement does not directly suggest a fear of appearing emotionally immature. B: Embarrassing herself by crying in public - This choice is incorrect as the teen's statement does not mention a fear of embarrassment. C: Losing the support of her friends and family - This choice is incorrect as the teen's statement does not indicate a fear of losing support from others.

Correct Answer: D

Rationale: The correct answer is D: Adventitious crisis. This type of crisis is triggered by external events such as moving to a retirement center after 50 years in the same home. The sudden change in environment can lead to distress and challenges for the elderly couple, causing an adventitious crisis. Acute grief (A) and traumatic grief (B) are typically associated with the loss of a loved one, not a change in lifestyle. Chronic sorrow (C) refers to ongoing grief related to a chronic illness or disability, which is not the case in this scenario.

Correct Answer: D

Rationale: The correct answer is D because selecting foods high in vitamins A, C, and E supports the principles of the cross-links theory of aging, which focuses on the accumulation of damage from oxidative stress. Vitamins A, C, and E are antioxidants that help combat oxidative stress and reduce the formation of cross-links in tissues. This intervention can potentially slow down the aging process by reducing cellular damage. Choice A is incorrect because applying an elastin-sustaining moisturizer does not directly address the oxidative stress aspect of the cross-links theory of aging. Choice B is incorrect as assessing family history for genetic diseases does not specifically target the mechanisms involved in the cross-links theory of aging. Choice C is incorrect because questioning about exposure to environmental toxins may be important for overall health but is not directly related to the principles of the cross-links theory of aging.

Correct Answer: D

Rationale: The correct answer is D because it accurately reflects the typical memory impairment after ECT treatments. ECT affects both recent and remote memory, leading to profound confusion and cognitive difficulties. This is due to the disruption of neural pathways involved in memory consolidation and retrieval. Choice A is incorrect as ECT does have predictable effects on memory. Choice B is incorrect because patients typically have more difficulty with recent memory than remote memory. Choice C is also incorrect as patients usually experience more than just mild difficulty remembering recent events; the memory impairment is more severe than just forgetting what was eaten for breakfast.

Correct Answer: A

Rationale: The correct answer is A. An impulsive child typically acts without thinking or considering consequences, such as running into the street without looking. This behavior is impulsive, risky, and disregards safety instructions. Choices B and C describe behaviors that are more indicative of other issues like hyperactivity or hallucinations. Choice D suggests difficulty concentrating, which is not directly related to impulsivity. In summary, the key characteristic of an impulsive child is acting quickly without considering potential dangers or instructions.

Correct Answer: A

Rationale: The correct answer is A: Implement suicide precautions. This is the highest priority because the patient has a plan for suicide, which poses an immediate risk to their safety. Implementing suicide precautions involves ensuring the patient's environment is safe, removing any potential means of self-harm, and closely monitoring the patient to prevent any suicide attempts. Choice B is incorrect because offering high-calorie snacks and fluids frequently addresses the physical aspect of weight loss but does not address the immediate safety concern of suicide. Choice C is incorrect because assisting the patient to identify personal strengths is important for building self-esteem but is not the highest priority when the patient is at risk for suicide. Choice D is incorrect because observing the patient for therapeutic effects of antidepressant medication is important but not as urgent as ensuring the patient's safety in the case of suicidal ideation.

Correct Answer: B

Rationale: The correct answer is B because it emphasizes the nurse's role in actively working with the patient to address interpersonal problems. The nurse's initial role is to provide support and assistance to the patient in resolving their issues collaboratively. Choice A focuses on medical treatment and collaboration with the doctor, not specifically addressing interpersonal problems. Choice C solely emphasizes the role of medications in improving the patient's well-being, neglecting the interpersonal aspect. Choice D suggests passing off the responsibility to other professionals, which contradicts the nurse's initial role as a source of help for the patient. In summary, choice B is correct because it highlights the nurse's active involvement in solving the patient's interpersonal problems.

Correct Answer: C

Rationale: The correct answer is C: Medications the patient has recently taken. This information is crucial because certain medications can cause symptoms of delirium or exacerbate confusion in elderly patients. By reviewing the patient's recent medications, healthcare providers can identify potential drug-induced causes of confusion and adjust the treatment accordingly. Choice A (Evidence of spasticity or flaccidity) is incorrect because these symptoms are more related to neurological conditions such as stroke or spinal cord injury, not specifically delirium. Choice B (The patient’s level of motor activity) is not as relevant in distinguishing delirium from other problems as medication history, as motor activity can be influenced by various factors. Choice D (Level of preoccupation with somatic symptoms) is also less relevant compared to medication history in differentiating delirium, as somatic symptoms may not always directly indicate the underlying cause of confusion in elderly patients.
