The nurse is administering subcutaneous enoxaparin to a client following knee replacement surgery to prevent a deep vein thrombosis. Which laboratory result requires immediate action by the nurse?

Reference Range:

Hematocrit [42% to 52% (0.42 to 0.52 volume fraction)]

Platelets [150,000 to 400,000/mm (150 to 400 x 10L)

Creatinine (0.5 to 1.1 mg/dL (44 to 97 μmol/L)]

Blood Urea Nitrogen (BUN) [10 to 20 mg/dl (3.6 to 7.1 mmol/L)]

A) Bronchitis: Methylphenidate, a central nervous system stimulant, is not contraindicated in clients with bronchitis. While caution may be warranted in individuals with respiratory conditions due to potential stimulant effects, bronchitis alone does not necessitate specific precautions or contraindications for methylphenidate use.

B) Diabetes mellitus: Methylphenidate use does not typically pose significant risks for individuals with diabetes mellitus. While stimulant medications may affect appetite and blood glucose levels, they are not contraindicated in clients with diabetes. Monitoring blood glucose levels may be prudent, but it is not the primary concern when reviewing the medical record before administering methylphenidate.

C) Hypertension: Reviewing the medical record for hypertension is essential before administering methylphenidate. Stimulant medications like methylphenidate can increase heart rate and blood pressure, potentially exacerbating hypertension or cardiovascular conditions. Clients with uncontrolled hypertension may require dose adjustments or alternative treatments to mitigate cardiovascular risks associated with methylphenidate use.

D) Hypercholesterolemia: Methylphenidate is not contraindicated in clients with hypercholesterolemia. While stimulant medications may have minor effects on lipid profiles, they are not typically considered significant enough to warrant specific precautions or contraindications in individuals with hypercholesterolemia.

A) Deep-fried shrimp: While deep-fried foods are generally high in fat and calories, there is no specific contraindication for clients taking phenelzine to avoid deep-fried shrimp. However, clients with hypertension may benefit from reducing their intake of high-fat foods.

B) Pan-seared catfish: Pan-seared catfish is a relatively lean protein source and does not contain ingredients known to interact with phenelzine. However, clients with hypertension may benefit from limiting their intake of high-sodium foods, such as pan-seared catfish if it is prepared with added salt.

C) Pepperoni pizza: Pepperoni pizza is a high-sodium food due to its processed meat toppings and cheese, and it may contain ingredients that interact with phenelzine. Phenelzine is a monoamine oxidase inhibitor (MAOI), and consuming foods high in tyramine, such as aged or fermented foods like pepperoni, can lead to hypertensive crisis. Therefore, the nurse should instruct the client to avoid pepperoni pizza to prevent potential interactions and exacerbation of hypertension.

D) Beef tips with gravy: While beef tips with gravy may be high in sodium depending on how it is prepared, there is no specific contraindication for clients taking phenelzine to avoid this food. However, clients with hypertension may benefit from choosing lean cuts of beef and limiting their intake of high-sodium gravies.
