A nurse is preparing to instill 840 mL of enteral nutrition via a patient’s gastrostomy tube over 24 hours using an infusion pump.

How many mL/hr should the nurse set the infusion pump to deliver?

Choice A rationale

Granulation tissue forming at the bottom of the wound bed is a characteristic of secondary intention healing, not primary intention. In secondary intention, the wound is left open and fills with granulation tissue.

Choice B rationale

A wound that was contaminated at the time of injury would likely require secondary intention healing to allow for cleaning and observation of the wound. This is not typical of primary intention healing.

Choice C rationale

Prolonged healing of the wound is not a characteristic of primary intention healing. In primary intention, the wound edges are brought together (approximated), which allows for rapid healing.

Choice D rationale

In primary intention healing, the skin edges of the wound are sutured closed. This is the most distinctive feature of primary intention healing, as it allows for minimal scar formation and quick healing.

The correct answer is choicea. Increase daily caloric intake by 300 to 400 calories,b. Consume folic acid supplements daily, andd. Take daily iron and calcium supplements.

Choice A rationale:

Pregnant teenagers need to increase their daily caloric intake by 300 to 400 calories to support the growth and development of the fetus.

Choice B rationale:

Folic acid is crucial for preventing neural tube defects in the developing fetus.Daily supplementation is recommended.

Choice C rationale:

Pregnant teenagers need to increase their protein intake to support fetal growth and maternal health.Maintaining current protein intake is not sufficient.

Choice D rationale:

Iron and calcium are essential for the development of the fetus and the health of the mother.Daily supplementation helps prevent deficiencies.

Choice E rationale:

Limiting weight gain to no more than 15 pounds is not recommended.Healthy weight gain during pregnancy varies but is generally higher than 15 pounds to support fetal development.
