You are reviewing lab findings on an 88-year-old patient and note that her vitamin B12 level is low. A decrease in B12 among older adults frequently results in:

Correct Answer: B

Rationale: In older adults, a decrease in vitamin B12 levels often leads to pernicious anemia. Pernicious anemia is caused by a lack of intrinsic factor, a protein needed for B12 absorption in the gut. Without sufficient B12, red blood cell production is impaired, leading to anemia characterized by enlarged red blood cells. This condition is common in older adults due to age-related changes in the stomach lining affecting intrinsic factor production. Option A, aplastic anemia, is not directly related to B12 deficiency but rather involves bone marrow failure leading to decreased production of all blood cells. Option C, folate anemia, results from a deficiency in folic acid, not B12. Option D, Wernicke's anemia, is not a recognized medical condition; Wernicke's encephalopathy is a neurological disorder caused by thiamine (B1) deficiency. Understanding the relationship between vitamin B12 deficiency and pernicious anemia is crucial for healthcare providers caring for older adults. Regular monitoring of B12 levels and prompt treatment with B12 supplements or injections can help prevent complications associated with pernicious anemia and improve patient outcomes.

Correct Answer: D

Rationale: In the context of mental disorders, anxiety is a common symptom that manifests in various ways across different conditions. Anxiety disorders, such as generalized anxiety disorder, panic disorder, and social anxiety disorder, are characterized by excessive and persistent feelings of worry, fear, or nervousness. These feelings can significantly impact a person's daily functioning and quality of life. Therefore, option D, anxiety, is the correct answer as it directly relates to mental health conditions. Anger, on the other hand, while present in some mental disorders like intermittent explosive disorder, is not a universal symptom and does not encompass the wide range of mental health conditions that may present with other symptoms. Sleep deprivation can be a consequence of mental health issues like insomnia or mood disorders, but it is not a primary symptom used to diagnose mental disorders. Speech abnormalities are more commonly associated with neurological conditions or developmental disorders rather than primary mental health diagnoses. Educationally, understanding the specific symptoms associated with mental disorders is crucial for healthcare professionals to accurately assess, diagnose, and treat individuals experiencing these conditions. By recognizing the nuances of symptoms like anxiety, professionals can provide appropriate interventions and support for individuals struggling with mental health issues.

Correct Answer: A

Rationale: In the context of pharmacology and mental health, it is important to consider the impact of anxiety on the body and how nutrition can play a role in managing anxiety symptoms. Option A, high blood pressure, is the correct answer in this scenario. When a client is experiencing anxiety, their body's stress response is activated, leading to an increase in blood pressure. By providing educational information on nutrition, specifically focusing on a diet low in sodium and rich in fruits, vegetables, and whole grains, individuals can better manage their blood pressure levels, which can in turn help reduce anxiety symptoms. Options B, increased heart rate, and C, decreased oxygen supply, are common physiological responses to anxiety as well. However, these are more directly related to the body's immediate stress response rather than being influenced by nutrition. It is important to address these symptoms through relaxation techniques, stress management strategies, and potentially medication if necessary. Option D, muscle relaxation, is also a relevant aspect of managing anxiety; however, nutrition plays a more significant role in affecting blood pressure levels, which is why option A is the most appropriate choice in this context. Educating clients on a well-balanced diet and its impact on blood pressure can empower them to make positive lifestyle changes to support their mental health.

Correct Answer: D

Rationale: In the context of a client diagnosed with anxiety, the high-priority nursing diagnosis and intervention would be "Muscle relaxation" (Option D). This is the correct answer because anxiety often manifests physically, leading to muscle tension and discomfort. By promoting muscle relaxation techniques such as deep breathing exercises, progressive muscle relaxation, or guided imagery, nurses can help alleviate the physical symptoms of anxiety and promote overall well-being. The other options (A, B, and C) are incorrect in this scenario. High blood pressure (Option A) and increased heart rate (Option B) are physiological responses to anxiety but are not direct nursing diagnoses or interventions for anxiety itself. While anxiety can indeed lead to increased heart rate and blood pressure, addressing these symptoms alone may not effectively address the root cause of anxiety. Similarly, decreased oxygen supply (Option C) is not a high-priority nursing diagnosis for a client with anxiety unless there are specific respiratory issues present. In the context of anxiety, focusing on promoting relaxation techniques and addressing the psychological aspects of anxiety would be more beneficial than solely focusing on oxygen supply. In an educational context, it is crucial for nursing students to understand the holistic approach to managing anxiety. Recognizing the physical manifestations of anxiety and implementing appropriate interventions like muscle relaxation techniques can significantly improve patient outcomes and enhance overall quality of care. Nurses play a vital role in addressing both the physical and psychological aspects of anxiety to support the holistic well-being of their patients.

Correct Answer: A

Rationale: In the context of pharmacology, especially when considering a client's response to stimuli, it is crucial for nurses to understand the principles of sensory overload. The correct answer, A) Reducing activity, is the most appropriate nursing intervention to help a client avoid dealing simultaneously with multiple stimuli. By reducing activity, the nurse can control the environment to minimize excessive stimuli that may overwhelm the client, allowing them to focus on one stimulus at a time. This is particularly important when a client is on medications that can affect their sensory perception or cognitive function. Option B) Touching the client as often as possible is incorrect as it may actually increase stimuli for the client, especially if they are sensitive to touch or if it is not a preferred form of communication for them. Option C) Increasing bright lights can exacerbate sensory overload for a client, as bright lights can be overwhelming and distracting. Option D) Taking a position as close to the client as possible can also contribute to sensory overload by invading the client's personal space and adding another layer of stimuli to process. Educationally, understanding how to manage sensory overload is essential for nurses caring for clients on pharmacological treatments that can impact their sensory perception. By implementing appropriate interventions like reducing activity, nurses can create a therapeutic environment that promotes the client's well-being and aids in their recovery process.
