Which type of sexually-transmitted infection is caused by a protozoa (single-cell animal)?

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 caused by viruses (HPV, herpes) or bacteria (syphilis), not protozoa. Trichomoniasis is characterized by symptoms like vaginal discharge, itching, and discomfort during urination. Treatment typically involves antibiotics. In summary, Trichomoniasis is the only option caused by a protozoa, making it the correct answer.

Correct Answer: C

Rationale: The correct answer is C because as individuals age, there is a natural decrease in the ability of the lungs to efficiently exchange oxygen and carbon dioxide, leading to a decrease in oxygen levels in the blood. This is due to factors such as decreased lung elasticity, reduced respiratory muscle strength, and changes in lung structure. Explanation for other choices: A: Air sacs do not increase in the lungs with age, rather they may lose elasticity. B: Chest muscles tend to weaken with age, not strengthen. D: Lung capacity typically decreases with age due to changes in lung function and structure, not increases.

Correct Answer: D

Rationale: The correct answer is D: Burnout. Burnout is the result of prolonged stress and frustration, leading to mental and physical exhaustion. It specifically occurs in response to chronic work-related stress. Agitation (A) refers to a state of anxiety or nervousness. Social anxiety disorder (B) is a mental health condition characterized by intense fear of social situations. Sundowning (C) is a phenomenon associated with confusion and agitation in the late afternoon or evening, commonly seen in individuals with dementia. Therefore, only burnout accurately describes the condition of mental or physical exhaustion due to prolonged stress and frustration.

Correct Answer: A

Rationale: The correct answer is A: Biopsy. A biopsy involves the removal of a sample of tissue for diagnostic purposes. It is commonly used to detect cancer or other diseases. Arthroscopy (B) is a minimally invasive surgical procedure to visualize, diagnose, and treat problems inside a joint. Telemetry (C) is the automatic measurement and transmission of data from remote sources. Bronchoscopy (D) is a procedure to examine the airways in the lungs. Only biopsy directly involves the removal of tissue for diagnosis.

Correct Answer: A

Rationale: The correct answer is A because it involves providing physical guidance to assist the resident in performing a task independently. By placing her hand around the resident's hand to help with bringing the spoonful of food to her mouth, the NA is offering direct physical support without taking over the task completely. This method promotes the resident's independence by allowing her to actively participate in the action with assistance. Option B simply instructs the resident to take a sip of water, which does not involve physical cueing. Option C involves verbal instruction, which is not a physical cue. Option D lists steps for the resident to complete, which may be helpful but does not involve physical guidance.
