Correct Answer: D

Rationale: Chlamydia is a sexually transmitted infection that requires notification and intervention due to its public health implications and potential complications if left untreated. Reporting Chlamydia is crucial to initiate appropriate treatment, prevent further spread of the infection, and provide necessary counseling to affected individuals. While other infections like herpes simplex, human papillomavirus, and candidiasis are also significant, Chlamydia is particularly important to report in this context.

Correct Answer: A

Rationale: Pregabalin is commonly used to manage pain associated with fibromyalgia. It works by reducing the number of pain signals sent out by damaged nerves. Lorazepam is a benzodiazepine used for anxiety, not pain management. Colchicine is primarily used for gout treatment, and codeine, while an analgesic, is not typically the first-line choice for fibromyalgia pain due to its potential for side effects and misuse.

Correct Answer: B

Rationale: Toddlers with acute lymphocytic leukemia may have compromised immune systems and need to avoid activities that increase infection risk. Playing with a large plastic truck is a safe and engaging activity that does not pose a high risk of infection. This choice also promotes physical activity and creativity, which are beneficial for a toddler's development during illness.

Correct Answer: A

Rationale: Children with varicella (chickenpox) are contagious until all vesicles are crusted over. The contagious period starts 1-2 days before the rash appears and continues until all lesions are dried and crusted. It is important to educate healthcare providers about the contagious period to prevent the spread of the virus to susceptible individuals.

Correct Answer: A

Rationale: The correct answer is to use three-pronged grounded plugs because they are safer and reduce the risk of electrical fires. Option B is incorrect as covering extension cords with a rug can pose a fire hazard. Option C is incorrect; tingling sensations around a cord indicate an electrical issue, not proper functioning. Option D is unsafe; plugs should be removed from the socket by pulling the plug, not the cord, to prevent damage and reduce the risk of electrical hazards.
