Situational stressor

Correct Answer: A

Rationale: Step 1: Loss of job is a situational stressor as it involves a significant change or loss in one's life, leading to emotional distress and uncertainty. Step 2: Job interview may cause stress, but it is a specific event, not a broader situational stressor like losing a job. Step 3: Choices C and D are incomplete, making them incorrect as they do not provide relevant information related to situational stressors. Summary: Loss of job is the correct answer as it aligns with the definition of a situational stressor, while the other choices are incorrect due to their lack of direct relevance to the concept.

Correct Answer: A

Rationale: The correct answer is A because insomnia is a common symptom of depression. When someone is depressed, they may have difficulty falling asleep or staying asleep. This is often due to racing thoughts, feelings of worthlessness, or changes in brain chemistry. In contrast, the inability to cry (option B) is not a defining feature of depression. Options C and D are blank and irrelevant. In summary, the inability to sleep is a hallmark symptom of depression, making option A the correct choice.

Correct Answer: B

Rationale: The correct answer is B: Between the lips. Oral temperature measurement should be taken between the lips using a thermometer. This method ensures accurate reading by placing the thermometer in the sublingual pocket under the tongue. Choice A (Sublingual) is incorrect as it refers to the correct location within the oral cavity. Choice C and D are incomplete options and do not provide a valid alternative method for taking oral temperature.

Correct Answer: A

Rationale: In the context of client safety in nursing, understanding the role of hormones in regulating body temperature is crucial for providing effective care. Option A is correct because hormones such as thyroid hormone and cortisol can influence the body's temperature regulation mechanism. Thyroid hormone, for example, can increase metabolism and heat production, leading to an increase in body temperature. By choosing option A, students demonstrate their knowledge of this important physiological process. Option B is incorrect because it does not address the role of hormones in temperature regulation. This option might be tempting for students who are not familiar with the specific physiological mechanisms involved in temperature control, but it lacks the depth needed to explain the relationship between hormones and body temperature. Option C is also incorrect as it does not provide any information related to hormones and their impact on body temperature. This option may mislead students who are not attentive to the specific details of endocrine system function and its relevance to maintaining homeostasis. Option D is incorrect as it does not mention anything about hormones and their connection to temperature regulation. Without this essential information, students selecting this option would not demonstrate an understanding of the physiological processes that govern body temperature. In an educational context, emphasizing the role of hormones in temperature regulation helps students grasp the intricate mechanisms that ensure client safety in nursing practice. By understanding how hormones influence body temperature, nurses can better assess and respond to changes in their patients' condition, contributing to effective care delivery and patient outcomes.

Correct Answer: A

Rationale: The correct answer is A. A too narrow cuff causes false high blood pressure readings because it compresses the artery, leading to an overestimation of pressure. On the other hand, a too wide cuff causes false low readings as it doesn't provide enough pressure to occlude the artery, resulting in underestimation of blood pressure. Therefore, it is crucial to use an appropriate cuff size to ensure accurate blood pressure measurements. Choices B, C, and D are incorrect because they do not accurately describe the effects of using incorrect cuff sizes on blood pressure readings.
