One function of the blood is to

Correct Answer: C

Rationale: The correct answer is C: Control pH levels. Blood helps maintain a stable pH level in the body by acting as a buffer system to prevent drastic changes in acidity or alkalinity. This is crucial for proper function of enzymes and other biochemical processes. Incorrect choices: A: Remove oxygen from the cells - This is incorrect as blood carries oxygen to cells, not removes it. B: Control blood vessel size - While blood vessels can regulate their size, it is not the primary function of blood. D: Increase body temperature - Blood does contribute to temperature regulation through circulation, but its primary role is not to increase body temperature.

Correct Answer: D

Rationale: Thyroid hormones, such as T3 and T4, are primarily responsible for regulating metabolism and growth in the body. They control how the body uses energy and help in the synthesis of proteins. Thyroid hormones do not directly influence heart rate and respiration (Choice A), bile production and potassium levels (Choice B), or kidney and liver function (Choice C). Thus, the correct answer is D as it aligns with the known functions of thyroid hormones.

Correct Answer: D

Rationale: The correct answer is D: Sharing a drug needle with an infected person. This is because HIV is transmitted through blood, and sharing needles can lead to direct blood-to-blood contact, increasing the risk of HIV transmission. Kissing on the cheek (A), shaking hands (B), and sharing utensils (C) do not involve direct blood contact, so the risk of HIV transmission through these methods is extremely low or non-existent.

Correct Answer: D

Rationale: The correct answer is D: Supine position. When using a pulse oximetry device, the supine position can lead to inaccurate readings due to potential compression of blood vessels. This can result in false low oxygen saturation readings. Avoiding the supine position ensures accurate readings. Choices A, B, and C are incorrect because excessive fluids, loose tape, and other factors do not directly impact the accuracy of pulse oximetry readings like the supine position does.

Correct Answer: C

Rationale: Certainly. The correct answer is C: Consider a compromise. This is because compromising involves finding a middle ground that is acceptable to all parties, promoting cooperation and reaching a mutually beneficial solution. It acknowledges the needs and perspectives of both sides, fostering understanding and maintaining relationships. In contrast, A (Never meet halfway) is rigid and ignores the importance of finding common ground. B (Always challenge policy) may escalate conflict and hinder finding a resolution. D (Antagonize coworkers) is counterproductive and worsens the situation by creating hostility. In summary, choosing to consider a compromise is the most effective and constructive approach to resolving conflicts.
