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 according to the American Heart Association guidelines. The top number (systolic pressure) of 120 is considered elevated (120-129) and the bottom number (diastolic pressure) of 85 is within the elevated range (80-89). Choice B (110/76) falls within the normal range for blood pressure. Choice C (118/72) also falls within the normal range. Choice D (114/66) has a systolic pressure within the normal range but a diastolic pressure below the normal range, therefore not considered elevated.

Correct Answer: B

Rationale: The correct answer is B: Testicular cancer is a common form of cancer in younger men. This is because testicular cancer primarily affects men between the ages of 15 to 44. It is one of the most common forms of cancer in this age group. The other choices are incorrect because: A) Testicular cancer does not begin within the ovaries, as it specifically affects the testicles in men; C) Testicular cancer is not similar to chlamydia, which is a sexually transmitted infection caused by bacteria; D) Testicular cancer can be detected through self-exams and does not necessarily require a doctor's exam for detection.

Correct Answer: B

Rationale: The correct answer is B: Broken skin between the toenails. This should be reported as a possible sign of a pressure injury because it indicates skin breakdown, which can be a precursor to pressure ulcers. Broken skin between the toenails is a specific area where pressure injuries can develop due to friction and pressure. It is important to report this promptly to prevent further damage and provide appropriate care. A: Intact skin is not a sign of a pressure injury, so it does not need to be reported. C: Clean skin is a positive sign of good hygiene and does not necessarily indicate a pressure injury. D: Adequate resident hydration is important for overall health but does not directly relate to pressure injuries.

Correct Answer: B

Rationale: The correct answer is B: Act as an air filter cleaning inhaled air. The respiratory system filters and cleans the air we breathe, removing harmful particles and pollutants. This is crucial for maintaining healthy lungs and preventing respiratory issues. Choice A is incorrect as moving lymph is a function of the lymphatic system. Choice C is incorrect as controlling body temperature is primarily regulated by the thermoregulatory system. Choice D is incorrect as protecting internal organs from injury is a function of the skeletal system and other structures such as muscles and fat.

Correct Answer: C

Rationale: The correct answer is C because dementia indeed affects the ability to reason and remember due to brain damage. It is not always reversible (A), as it is often progressive and irreversible. It is not a sudden state of confusion (B), but a gradual decline in cognitive function. Lastly, dementia is a serious illness (D) that can significantly impact a person's quality of life and independence.
