Shingles is a viral infection caused by the same virus that causes _______ and can occur in anyone who has had it.

Correct Answer: C

Rationale: The correct answer is C: Chickenpox. Shingles is caused by the reactivation of the varicella-zoster virus, which is the same virus that causes chickenpox. After a person has had chickenpox, the virus remains dormant in the body and can reactivate later in life, causing shingles. Scabies (A) is a skin infestation caused by mites, not a viral infection. Herpes (B) is caused by the herpes simplex virus, not the varicella-zoster virus. Eczema (D) is a skin condition characterized by inflammation, not a viral infection.

Correct Answer: C

Rationale: The correct answer is C (90 degrees) because excessive bending or flexion of the hip joint post total hip replacement can lead to dislocation. Keeping the hip flexion limited to 90 degrees helps prevent this complication while allowing for functional movements. Choices A, B, and D are incorrect as they exceed the safe range of hip flexion post-surgery, increasing the risk of dislocation and compromising the success of the procedure.

Correct Answer: B

Rationale: The correct answer is B because using dishes without patterns and simple place settings can help residents with Alzheimer's disease focus on their meal. Complex patterns can be distracting and confusing for them. This approach promotes independence and reduces agitation during mealtime. Choice A is incorrect because presenting multiple types of food on the plate can overwhelm and confuse the resident, leading to decreased appetite and difficulty eating. Choice C is incorrect as withholding food until the resident is very hungry can lead to frustration, increased agitation, and may even result in malnutrition. Choice D is incorrect because serving steaming hot food can pose a burn risk to the resident if they have sensory impairments or cognitive deficits that prevent them from recognizing the temperature.

Correct Answer: B

Rationale: The correct answer is B: Having unprotected sex puts a person at a high risk for HIV/AIDS. This statement is true because HIV is primarily transmitted through unprotected sexual contact. It is important to practice safe sex to prevent the transmission of HIV. Choice A is incorrect because there is currently no cure for AIDS, only treatments to manage the virus. Choice C is incorrect as Standard Precautions should always be practiced to prevent the spread of infections, including with individuals who have AIDS. Choice D is incorrect as it is illegal to discriminate against an individual with HIV/AIDS in the workplace.

Correct Answer: A

Rationale: The correct answer is A: Gurgling. Symptoms of respiratory distress often include gurgling sounds due to fluid accumulation in the airway. Decreased respiratory rate (B) is not typically seen in respiratory distress, as it usually involves rapid or labored breathing. Redness of the skin (C) may indicate other conditions but is not specific to respiratory distress. Apathy (D) is a non-specific symptom and is not typically associated with respiratory distress.
