Chemicals called ________ are stored in neurons and released when the cell is stimulated by a signal.

Correct Answer: D

Rationale: The correct answer is D: neurotransmitters. Neurons store and release neurotransmitters in response to signals to communicate with other neurons or target cells. Neurotransmitters play a crucial role in transmitting signals across synapses. Toxins (A) are harmful substances, not involved in neuronal communication. Cytokines (B) and chemokines (C) are signaling molecules involved in immune responses, not neuronal communication. Therefore, the correct choice is neurotransmitters.

Correct Answer: A

Rationale: The correct answer is A: Reflexes will be normal. In a patient with a head injury resulting from trauma and no other injuries, deep tendon reflexes are typically unaffected by the injury. The brain stem controls deep tendon reflexes, and since there are no other injuries, the reflexes should remain normal. Choices B, C, and D are incorrect because they do not align with the typical response of deep tendon reflexes in a head injury without other injuries. Choice B stating that reflexes cannot be elicited is incorrect as deep tendon reflexes are usually intact in this scenario. Choice C suggesting all reflexes will be diminished but present is incorrect as deep tendon reflexes are typically not affected by head injuries. Choice D stating that some reflexes will be present depending on the area of injury is incorrect because deep tendon reflexes are primarily controlled by the brain stem, which is not directly affected in this situation.

Correct Answer: C

Rationale: Rationale for Choice C: Shifting the focus from somatic symptoms to feelings is crucial as it helps address the underlying emotional factors contributing to the somatic system disorder. By exploring the patient's emotions and addressing them, the nurse can help the patient gain insight into their condition and potentially reduce the somatic symptoms. This intervention promotes holistic care by addressing both physical and emotional aspects of the disorder. Summary of other choices: A: Implying that somatic symptoms are not real can invalidate the patient's experience and hinder therapeutic progress. B: Helping the patient suppress feelings of anger can lead to emotional repression and exacerbate somatic symptoms. D: Investigating each physical symptom as soon as it is reported may overlook the emotional root causes of the somatic system disorder.

Correct Answer: A

Rationale: Correct Answer: A. Depersonalization Rationale: 1. Depersonalization involves feeling detached from oneself or reality, as described by the patient. 2. The patient's description of feeling like they are looking through a cloudy window aligns with depersonalization symptoms. 3. Interference with work and study suggests significant distress, a common feature of depersonalization disorder. Summary of other choices: B. Hypochondriasis: Involves excessive worry about having a serious illness, which is not indicated in the patient's complaint. C. Dissociation: While depersonalization is a type of dissociative symptom, it specifically refers to feeling detached and unreal, not necessarily a broader dissociative disorder. D. Malingering: Involves feigning or exaggerating symptoms for secondary gain, which is not evident in the patient's genuine distress and impairment.
