A nurse is caring for a patient who has a respiratory infection.
What technique should the nurse use when performing nasotracheal suctioning for the patient?

Choice A rationale

Injecting 5 units of air into the bottle of regular insulin is the second step in the procedure. This is done after injecting air into the NPH insulin bottle. The purpose of this step is to pressurize the vial, making it easier to withdraw the insulin.

Choice B rationale

Withdrawing the correct dose of NPH insulin from the bottle is the last step in the procedure. This is done after withdrawing the regular insulin to prevent contamination of the regular insulin with the NPH insulin.

Choice C rationale

Injecting 10 units of air into the bottle of NPH insulin is the first step in the procedure. This is done before injecting air into the regular insulin bottle. The purpose of this step is to pressurize the vial, making it easier to withdraw the insulin.

Choice D rationale

Withdrawing the correct dose of regular insulin from the bottle is the third step in the procedure. This is done after injecting air into the regular insulin bottle and before withdrawing the NPH insulin. The purpose of this step is to ensure that the correct dose of regular insulin is administered.

Choice A rationale

Granulation tissue covering the wound bed is a positive sign of wound healing. Granulation tissue is a key component of the wound healing process, typically forming during the proliferation phase. It consists of new connective tissue and tiny blood vessels that develop in the wound bed as part of the body’s response to injury. Therefore, the presence of granulation tissue covering the wound bed indicates an improvement in the patient’s condition.

Choice B rationale

Slight erythema at the wound edges could be a sign of inflammation or infection. Erythema, or redness of the skin, is often associated with inflammation or infection. While it can be a normal part of the healing process, persistent or increasing erythema could indicate a problem such as infection or irritation. Therefore, slight erythema at the wound edges does not necessarily indicate an improvement in the patient’s condition.

Choice C rationale

The surrounding tissue being warm to touch could be a sign of inflammation or infection. When skin feels hot to the touch, it often means that the body’s temperature is hotter than normal. This can happen due to an infection or an illness, but it can also be caused by an

environmental situation that increases body temperature. Therefore, the surrounding tissue being warm to touch does not necessarily indicate an improvement in the patient’s condition.

Choice D rationale

The patient reporting pain as a 2 on a scale from 0 to 10 could indicate that the patient’s pain is minor. On a pain scale, a score of 2 usually indicates minor pain. However, pain is a subjective experience and can vary greatly among individuals. Therefore, while a lower pain score generally suggests less severe pain, it does not necessarily indicate an improvement in the patient’s overall condition.
