Correct Answer: C

Rationale: Stool positive for occult blood indicates potential gastrointestinal bleeding, a serious adverse effect of enoxaparin (a low-molecular-weight heparin), requiring immediate reporting to the provider.
Choice A is incorrect because a hemoglobin of 10 g/dL is low but not critical unless accompanied by signs of active bleeding; it should be monitored.
Choice B is incorrect because a platelet count of 100,000/mm3 is low but not immediately concerning unless trending downward or associated with bleeding.
Choice D is incorrect because INR is not used to monitor enoxaparin; it is relevant for warfarin therapy, and 1.2 is within normal limits.

Correct Answer: B

Rationale: Reporting signs of infection is critical with prednisone due to immunosuppression. It's taken with food, weight gain is expected, and stopping abruptly risks adrenal crisis.

Correct Answer: A

Rationale: Soy products can interfere with levothyroxine absorption by binding to the medication in the gastrointestinal tract, reducing its effectiveness, and should be avoided at the same time as the dose.
Choice B is incorrect because bananas do not affect levothyroxine absorption and are safe to consume.
Choice C is incorrect because lean beef does not significantly impact levothyroxine absorption, though high-protein meals may have a minor effect if taken concurrently.
Choice D is incorrect because carrots do not interfere with levothyroxine absorption.

Correct Answer: D

Rationale:
Choice A is wrong because synthetic fabrics can generate static electricity, which can also cause sparks and ignite oxygen. The client's bedding should be made of cotton or wool, which are natural fabrics that do not produce static electricity.
Choice B is wrong because petroleum jelly is a petroleum-based product that can react with oxygen and cause skin irritation or burns. The client should use water-based moisturizers to soothe the mucous membranes.
Choice C is wrong because alcohol-based cleaning products are also flammable and can cause fires or explosions when exposed to oxygen. The client should use mild soap and water to clean the equipment, and follow the manufacturer's instructions for maintenance. Nail polish remover contains acetone, which is a flammable substance that can ignite in the presence of oxygen. Using nail polish remover around the client can increase the risk of fire and burn injuries.

Correct Answer: A

Rationale: The nurse should ensure the state health department has been notified of the child's Lyme disease, as it is a reportable disease in most states. Reporting helps to monitor the incidence and prevalence of Lyme disease and to implement prevention and control measures.
Choice B is wrong because antitoxin is not used to treat Lyme disease. Antitoxin is a substance that neutralizes the effects of a toxin, such as botulism or tetanus. Lyme disease is caused by a bacterium called Borrelia burgdorferi, which can be treated with antibiotics.
Choice C is wrong because Lyme disease is not transmitted by sharing personal belongings. Lyme disease is spread to humans by the bite of infected ticks that carry the bacterium. The risk of getting Lyme disease can be reduced by avoiding tick-infested areas, wearing protective clothing, using insect repellent, and removing ticks promptly.
Choice D is wrong because skin necrosis is not a common complication of Lyme disease. Skin necrosis is the death of skin tissue due to lack of blood supply or infection. Lyme disease can cause a characteristic skin rash called erythema migrans, which is usually circular or oval and expands over time. Other possible signs and symptoms of Lyme disease include fever, headache, fatigue, joint pain, and neurological problems.
