A nurse is assessing a client who is in skeletal traction for a fractured left tibia. The nurse should identify that which of the following findings indicates altered tissue perfusion of the affected extremity?

A. This is an incorrect action. Inserting air in the tube and listening for gurgling sounds in the epigastric area is not a reliable method to confirm NG tube placement, as it can produce false-positive results due to air entering the stomach or intestines.

B. This is a correct action. Aspirating contents from the tube and verifying the pH level is a valid method to confirm NG tube placement, as gastric contents typically have a pH of less than 5.5, while intestinal or respiratory contents have a higher pH.

C. This is an incorrect action. Reviewing the medical record for previous x-ray verification of placement is not sufficient to confirm NG tube placement, as the tube can migrate or become dislodged after insertion. X-ray verification should be done initially and whenever there is doubt about the tube's position.

D. This is an incorrect action. Auscultating the lungs for adventitious breath sounds is not a specific method to confirm NG tube placement, as it can indicate other conditions such as pneumonia or pulmonary edema. It can also miss signs of respiratory complications due to NG tube misplacement, such as pneumothorax or bronchial obstruction.

Choice A reason

"I can use natural-skin condoms to prevent sexually transmitted infections." This statement is incorrect. Natural-skin or lambskin condoms are not recommended for preventing sexually transmitted infections (STIs). They may provide some protection against pregnancy but do not effectively protect against STIs. Clients should use latex or polyurethane condoms to reduce the risk of STIs.

Choice B reason

"I can use petroleum jelly as a lubricant with the condom." This statement is also incorrect. Petroleum jelly (Vaseline) and other oil-based lubricants can damage latex condoms, leading to a higher risk of breakage or failure. Clients should use water-based or silicone-based lubricants with latex or polyurethane condoms.

Choice C reason:

"I can re-use the condom one time after initial use." This statement is incorrect. Condoms are designed for single-use only. Reusing a condom increases the risk of breakage, failure, and the transmission of STIs or unwanted pregnancy. Clients should always use a new condom for each sexual act.

Choice D reason:

"I can store the condoms in the drawer of my nightstand." This statement is correct because it indicates that the client understands the proper storage of condoms. Storing condoms in a cool, dry place, such as a drawer or a condom case, helps protect them from damage or deterioration, ensuring they remain effective when needed.
