Depression

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: 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.

Correct Answer: B

Rationale: The correct answer is B, the hydrochloric acid. The stomach's defense against infection is mainly attributed to its acidic environment, created by the hydrochloric acid. This acid helps to kill ingested pathogens, preventing them from causing infections. Additionally, the low pH of the stomach acid aids in the breakdown of food and the activation of digestive enzymes. The other choices are incorrect as the intestines do not directly play a role in the stomach's defense against infection.

Correct Answer: B

Rationale: Development is about progress and improvement, which aligns with the concept of quality rather than quantity. Quality development focuses on enhancing effectiveness, efficiency, and overall value. Quantity, on the other hand, emphasizes the sheer volume or amount without considering the actual impact or value. Choice A is incorrect as development is not solely about quantity but more importantly about the quality of growth and advancement. Choices C and D are incomplete and do not provide any relevant information to determine the nature of development.
