The nurse is preparing to administer a feeding to a client with a gastrostomy tube. What should the nurse do before providing this feeding?

Measure vital signs.

Lower the head of the bed.

Verify tube patency.

Assist the client to a prone position.

Answer and Explanation

The Correct Answer is C

C. Before administering a feeding through a gastrostomy tube, it is essential to verify that the tube is patent (open and unobstructed). Tube patency ensures that the feeding formula or medication can flow freely into the stomach or intestines without encountering any blockages or resistance. The nurse should flush the tube with water to check for patency and ensure proper functioning before initiating the feeding.

A. Vital signs are typically assessed for overall health monitoring and to detect any immediate changes in the client's condition. However, they are not specifically required before every feeding via gastrostomy tube unless there are specific concerns about the client's stability.

B. This option is not typically necessary before administering a feeding through a gastrostomy tube. In fact, elevating the head of the bed to at least 30 to 45 degrees is often recommended during and after feeding to minimize the risk of aspiration. This position helps to promote digestion and reduce the likelihood of reflux or regurgitation of the feeding.

D. Assisting the client to a prone (face-down) position is unnecessary and potentially unsafe before administering a feeding through a gastrostomy tube. The recommended position for feeding via gastrostomy tube is typically semi-Fowler's position (elevated head of the bed), which helps prevent aspiration and facilitates digestion.

Correct Answer is A

Explanation

A. The JP drain helps prevent excessive accumulation of fluid in the wound by actively draining it away. If fluid were to accumulate excessively, it could impair wound healing and increase the risk of infection.

However, the primary purpose of the JP drain is to remove fluid rather than prevent its collection altogether.

B. The JP drain does not directly assess the degree of healing. Its primary function is to drain fluid from the wound to promote healing by preventing fluid accumulation, which could hinder healing. Assessing the degree of healing typically involves visual inspection of the wound by the healthcare provider rather than relying on the drain.

C. This is not the purpose of the JP drain. Healing generally occurs by the gradual migration of cells and tissues to close the wound, which is an internal process. The JP drain assists in the healing process by preventing complications due to fluid accumulation but does not influence healing from outside to inside.

D. While the JP drain itself does not directly prevent the entrance of microorganisms into the wound, it indirectly contributes to infection prevention by removing excess fluid. Accumulated fluid can provide a medium for bacterial growth, potentially leading to infection. By draining fluid effectively, the JP drain helps maintain a cleaner wound environment, reducing the risk of infection.

A. second intercostal space, left sternal border. B. third intercostal space, left sternal border. C. second intercostal space, right sternal border D. fourth intercostal space, left sternal border.

Correct Answer is A

Explanation

A. The pulmonic valve is best auscultated at the second intercostal space (ICS) on the left sternal border. This is where the area corresponding to the pulmonic valve is most accurately heard due to the anatomical positioning of the heart.

B. This area does not correspond to any valvular area.

C. This location corresponds to the aortic valve, not the pulmonic valve. The aortic valve is best auscultated at the second ICS, right sternal border.

D. This location corresponds to the tricuspid valve, not the pulmonic valve. The tricuspid valve is best auscultated at the fourth or fifth ICS along the left sternal border.
