A nurse is reviewing the medical history of a client prior to medication administration and notes a history of an anaphylactic reaction to penicillin.
The nurse should identify that which of the following medications is contraindicated for this client?
Vancomycin.
Clarithromycin.
Metronidazole.
Ceftriaxone.
The Correct Answer is D
Ceftriaxone is contraindicated for this client because it is a cephalosporin antibiotic, which has a similar structure to penicillin and can cause cross-reactivity in individuals with a penicillin allergy.
Choice A is wrong because Vancomycin is not a beta-lactam antibiotic and does not have cross-reactivity with penicillin.
Choice B is wrong because Clarithromycin is a macrolide antibiotic and does not have cross-reactivity with penicillin.
Choice C is wrong because Metronidazole is a nitroimidazole antibiotic and does not have cross-reactivity with penicillin.

Correct Answer is A
Explanation
Total parenteral nutrition (TPN) is a method of administration of essential nutrients to the body through a central vein.
TPN solutions are customized for each client’s needs, including the exact amount of calories and nutrients necessary for total nutritional needs.
Monitoring the client’s weight daily is important to determine if nutritional goals are being met and to assess fluid volume status.
Choice B is wrong because TPN solutions are concentrated and can cause thrombosis of peripheral veins, so they require a central venous catheter and should not be hung to gravity to infuse.
Choice C is wrong because TPN solution should not be titrated to blood pressure.
Choice D is wrong because the client’s blood glucose level should be monitored more frequently than weekly when receiving TPN.
Correct Answer is A
Explanation
Total parenteral nutrition (TPN) is a highly concentrated solution that provides nutrients to the body intravenously.
It is typically administered through a central venous access device, such as a central venous catheter or a peripherally inserted central catheter (PICC), because it can irritate the walls of smaller veins.
Choice B is wrong because Midline catheter, is not an appropriate route for TPN administration because it is not a central venous access device.
Choice C is wrong because Subcutaneous, is not an appropriate route for TPN administration because it is not given intravenously.
Choice D is wrong because Intraosseous, is not an appropriate route for TPN administration because it is typically used in emergency situations when intravenous access cannot be obtained.
