A nurse in a coronary care unit is admitting a patient who has had CPR following a cardiac arrest.

The patient is receiving lidocaine IV at 2 mg/min.
When the patient asks the nurse why he is receiving that medication, the nurse should explain that it has which of the following actions?

Choice A rationale

Nystagmus, which is involuntary eye movement, is not a common adverse effect of a platelet transfusion.

Choice B rationale

Bradycardia, or a slow heart rate, is not typically associated with platelet transfusions.

Choice C rationale

Chills can be an adverse effect of a platelet transfusion. This could be a sign of a reaction to the transfusion, such as an allergic reaction or a febrile non-hemolytic transfusion reaction.

Choice D rationale

Hypothermia is not a common adverse effect of a platelet transfusion.

Choice A rationale

A water heater temperature of 54.4°C (130°F) is a safety risk because it can cause burns. Older adults have thinner skin and are more susceptible to burns.

Choice B rationale

Electric cords behind furniture can be a safety risk because they can cause tripping or fire if the cords are damaged.

Choice C rationale

Throw rugs are a safety risk because they can slide underfoot and cause falls, especially in older adults who may have balance issues.

Choice D rationale

Raised toilet seats are not a safety risk. In fact, they are often recommended for older adults to prevent falls in the bathroom.

Choice E rationale

A bathtub with rails is not a safety risk. Rails can provide support and prevent falls when the older adult is entering or exiting the bathtub.
