A nurse is teaching a client about the benefits of exercise.
The nurse knows teaching has been effective when the client lists which of the following health benefits of exercise? (Select all that apply).

The proper length of the needle to administer a subcutaneous injection depends on the amount of adipose tissue over the muscle.

The needle should be long enough to reach the subcutaneous layer but not so long that it penetrates the muscle. The needle gauge and length vary depending on the patient’s size and the injection site

Choice A is wrong because the age of the client does not determine the needle length.

However, age may affect the amount of adipose tissue and muscle mass, which are factors to consider when choosing a needle length.

Choice B is wrong because the viscosity of the solution does not determine the needle length. However, viscosity may affect the needle gauge, which is the diameter of the needle.

Thicker solutions may require larger gauge needles to allow easier flow.

Choice D is wrong because the quantity of the solution does not determine the needle length.

However, quantity may affect the syringe size, which is the volume of medication that can be held by the syringe.

The syringe size should match the prescribed dose as closely as possible to ensure accuracy and ease of measurement.

Heat application increases blood flow and reduces muscle spasms, which can help relieve pain and promote healing. However, heat should not be applied for longer than 30 minutes at a time, as it can cause tissue damage and inflammation.

Choice A is wrong because maximum benefits do not occur within the first five minutes.

It takes time for heat to penetrate the tissues and cause vasodilation.

Choice C is wrong because the heat should not be left in place for at least one hour to be effective.

This can lead to burns, increased edema, and decreased blood flow.

Choice D is wrong because heat can not be left in place for as long as 12 hours without harmful effects.

This can cause severe tissue damage, infection, and necrosis.

Normal ranges for heat application are between 104°F and 113°F (40°C and 45°C).

The temperature should be checked frequently and adjusted according to the patient’s comfort and tolerance.

The skin should also be inspected for signs of erythema, blisters, or burns.
