Which of the following blood pressure measurements would be considered elevated?

Correct Answer: A

Rationale: The correct answer is A (120/85) because it falls within the elevated blood pressure range based on current guidelines. Elevated blood pressure is defined as systolic pressure between 120-129 mm Hg and diastolic pressure below 80 mm Hg. Choice B (110/76) is within normal range. Choice C (118/72) and D (114/66) are also within normal range. Thus, only choice A meets the criteria for elevated blood pressure.

This is supported by statistics and medical research. A, C, and D are incorrect: A: Testicular cancer does not begin within the ovaries. C: Testicular cancer is not similar to chlamydia; they are entirely different conditions. D: Testicular cancer can sometimes be detected by self-examination at home, not exclusively by a doctor.

Rationale: Correct Answer: B - Broken skin between the toenails Rationale: Broken skin between the toenails can indicate the presence of a pressure injury, also known as a pressure ulcer. Pressure injuries often start as damage to the skin, such as breaks or tears, and can progress to more severe stages if not addressed promptly. Summary of Other Choices: A: Intact skin - This is not a sign of a pressure injury as intact skin does not show any visible damage or breakdown. C: Clean skin - Clean skin does not necessarily indicate the presence of a pressure injury, as cleanliness alone does not provide information on skin integrity. D: Adequate resident hydration - While hydration is important for overall skin health, it is not a direct indicator of a pressure injury.

C: Body temperature regulation is mainly controlled by the thermoregulatory system, not the respiratory system. D: Protection of internal organs from injury is primarily the function of the skeletal and muscular systems, not the respiratory system.
