Stress, except

Correct Answer: B

Rationale: The correct answer is B: Happy. Stress typically leads to increased vital signs (choice A) such as heart rate and blood pressure due to the body's fight or flight response. Choice C and D are incomplete options. In summary, stress does not typically result in feelings of happiness; instead, it often leads to negative emotions and physiological changes.

Correct Answer: A

Rationale: The correct answer is A: Birthmark. A macule is a flat, discolored spot on the skin that is smaller than 1 cm in diameter. Birthmarks are common pigmented or vascular skin lesions present at birth or appearing shortly after. Birthmarks are typically macules and can be various colors. In this case, the macule on the arm of the patient is likely a birthmark due to its appearance and location. Other choices are incorrect as they do not align with the characteristics of a birthmark or a macule.

Correct Answer: A

Rationale: The electronic thermometer is the most accurate temperature-taking method due to its precision and digital display. It provides quick and reliable readings, minimizing human error. Other choices like traditional mercury thermometers (B) are less accurate and can be hazardous. Infrared thermometers (C) may not provide as precise readings as electronic thermometers. Other options (D) are not valid alternatives for accurate temperature measurement.

Correct Answer: B

Rationale: The correct answer is B, intercourse with someone. Direct contact refers to physical contact between individuals that allows for the transmission of infectious agents, such as through sexual intercourse. Touching the patient's stuff (choice A) may lead to indirect contact transmission but not direct contact transmission as specified in the question. Choice C and D are not provided, so they are automatically incorrect. In summary, the correct answer is B because it involves direct physical contact that can transmit infectious agents, while the other choices are unrelated or do not meet the criteria for direct contact transmission.

Correct Answer: B

Rationale: The correct answer is B: Conduction. When you remove your sweater and start sweating, the heat transfer is through conduction. Conduction is the transfer of heat through direct contact between objects or substances. In this scenario, your body's heat is transferred to the surrounding air through direct contact, causing you to sweat. Radiation (choice A) involves heat transfer through electromagnetic waves, which is not applicable in this case. Choices C and D are not relevant to the situation described.
