A nurse is teaching a client who has a new prescription for total parenteral nutrition (TPN). Which of the following information should the nurse include in the teaching?
"The TPN will stimulate your appetite so that you'll be able to eat more food."
"The TPN contains medication that will help your digestive tract absorb nutrients."
"The TPN will provide nutrients while your bowels have time to rest."
"The TPN will help keep your bowels clear in case you need surgery."
The Correct Answer is C
C) "The TPN will provide nutrients while your bowels have time to rest": Total parenteral nutrition (TPN) is a method of providing nutrition intravenously to clients who are unable to tolerate or absorb adequate nutrients through the gastrointestinal tract. It bypasses the digestive tract entirely, delivering a balanced mixture of nutrients directly into the bloodstream. One of the primary indications for TPN is to provide nutritional support while allowing the gastrointestinal tract to rest, particularly in cases where the bowels are inflamed, injured, or unable to function properly. By bypassing the digestive system, TPN can provide essential nutrients to the body while reducing the workload on the gastrointestinal tract. Therefore, the nurse should include this information in the teaching to help the client understand the purpose and benefits of TPN therapy.
A) "The TPN will stimulate your appetite so that you'll be able to eat more food": TPN does not stimulate appetite. In fact, TPN is often used when the client cannot eat or tolerate oral intake due to various medical conditions or gastrointestinal issues. Therefore, this statement is incorrect and may confuse the client about the purpose of TPN therapy.
B) "The TPN contains medication that will help your digestive tract absorb nutrients": TPN does not contain medication to help the digestive tract absorb nutrients. Instead, TPN provides nutrients directly into the bloodstream, bypassing the need for digestion. This statement is inaccurate and does not accurately describe the mechanism of action of TPN.
D) "The TPN will help keep your bowels clear in case you need surgery": While TPN can help maintain nutritional status in clients who are unable to eat or tolerate oral intake, it is not primarily used to keep the bowels clear for surgery. Bowel preparation for surgery typically involves other interventions such as bowel rest, mechanical cleansing, or medication administration. Therefore, this statement is not directly related to the purpose of TPN therapy and may mislead the client about its intended use.

Correct Answer is D
Explanation
A) "This medication will not interfere with the effectiveness of oral contraceptives": Rifampin is known to induce hepatic enzymes, which can accelerate the metabolism of oral contraceptives and reduce their effectiveness. Therefore, it is essential for clients taking rifampin to use alternative or additional contraceptive methods to prevent pregnancy.
B) "You can continue to wear soft contact lenses while taking this medication": Rifampin can cause discoloration of bodily fluids, including tears, which may stain soft contact lenses. Therefore, clients taking rifampin should be advised to avoid wearing soft contact lenses during treatment to prevent discoloration and potential eye irritation.
C) "You should take this medication once each day at bedtime": Rifampin is usually taken once daily, but the specific timing may vary depending on the indication and healthcare provider's instructions. While taking rifampin at bedtime may be suitable for some clients, it is important to follow the prescribed dosing schedule provided by the healthcare provider.
D) "Your urine will turn orange while you are taking this medication": Rifampin can cause harmless discoloration of urine, tears, saliva, sweat, and other bodily fluids, turning them orange-red. This side effect is temporary and not harmful. However, informing the client about this potential effect is essential to prevent alarm or unnecessary concern.
Correct Answer is A
Explanation
A) Hypertension: Phenelzine is a monoamine oxidase inhibitor (MAOI) used as an antidepressant medication. It works by inhibiting the breakdown of neurotransmitters such as serotonin, norepinephrine, and dopamine in the brain. When phenelzine is taken with foods high in tyramine, such as aged cheese, a potentially dangerous interaction can occur. Tyramine-rich foods can cause the release of stored catecholamines, leading to a sudden increase in blood pressure, known as a hypertensive crisis. Symptoms of a hypertensive crisis can include severe headache, palpitations, chest pain, nausea, vomiting, and sweating. Therefore, hypertension is a manifestation of the interaction between phenelzine and aged cheese.
B) Bradycardia: Bradycardia, or slow heart rate, is not typically associated with the interaction between phenelzine and aged cheese. Instead, the interaction is more commonly associated with a sudden increase in blood pressure (hypertension).
C) Somnolence: Somnolence, or drowsiness, is a common side effect of phenelzine but is not specifically related to the interaction between phenelzine and aged cheese.
D) Diarrhea: Diarrhea is not typically associated with the interaction between phenelzine and aged cheese. Instead, the interaction is more commonly associated with a sudden increase in blood pressure (hypertension).
