Which number of respirations would be considered abnormal?

Correct Answer: B

Rationale: The correct answer is B (22 breaths per minute) as it falls outside the normal range of adult respiration rate, which is typically 12-20 breaths per minute. A (17 breaths per minute) is within the normal range, while C (13 breaths per minute) and D (12 breaths per minute) are below the normal range, indicating potential respiratory depression or bradypnea. Abnormal respiration rates can signify underlying health issues or respiratory distress.

Correct Answer: D

Rationale: The correct answer is D: Trichomoniasis. Trichomoniasis is caused by a protozoan parasite called Trichomonas vaginalis. This infection is transmitted through sexual contact. The other choices (A, B, C) are incorrect because HPV infection (A) is caused by a virus, genital herpes (B) is caused by the herpes simplex virus, and syphilis (C) is caused by the bacterium Treponema pallidum. Trichomoniasis is the only option caused by a protozoa, making it the correct answer in this context.

Correct Answer: D

Rationale: The correct answer is D: Systole. During systole, the ventricles of the heart contract to pump blood out into the circulation. This phase is essential for maintaining blood flow and delivering oxygen and nutrients to the body. A: Flatlining is incorrect as it refers to a complete absence of heart activity, which is a medical emergency. B: Diastole is incorrect as it is the phase when the heart muscle relaxes and fills with blood. C: Homeostasis is incorrect as it refers to the body's ability to maintain internal balance, not a specific phase of heart function.

Correct Answer: C

Rationale: The correct answer is C: Oxygen in the blood decreases. As people age, lung function declines, leading to reduced oxygen intake and exchange in the bloodstream. This is a normal age-related change due to decreased lung elasticity and efficiency. Choice A is incorrect as air sacs typically decrease in number and size with age. Choice B is incorrect because chest muscles tend to weaken, not strengthen, as individuals age. Choice D is also incorrect since lung capacity tends to decrease with age due to changes in lung tissue and decreased respiratory muscle strength.

Correct Answer: D

Rationale: The correct answer is D: Burnout. Burnout is a state of mental and physical exhaustion caused by prolonged stress and frustration. It is typically related to work or caregiving responsibilities. Agitation (A) refers to a state of anxiety or nervousness. Social anxiety disorder (B) is characterized by excessive fear of social situations. Sundowning (C) is a term used to describe the increase in confusion and agitation that occurs in the late afternoon or evening for individuals with dementia. Burnout specifically addresses the concept of exhaustion due to prolonged stress and frustration, making it the most appropriate choice in this context.
