Which of the following is a precaution associated with low molecular weight heparin (LMWH)?

Low molecular weight heparin (LMWH) is derived from unfractionated heparin and is commonly used as an anticoagulant. One important precaution to consider when using LMWH is related to allergies, particularly to pork, as many forms of heparin are sourced from porcine mucosa. Patients with a known allergy to pork may be at risk for an allergic reaction to LMWH, which can lead to serious complications.

Understanding this precaution is essential for healthcare providers, as it informs the decision-making process regarding anticoagulation therapy in patients with dietary restrictions or allergies. While the other options (sensitivity to aspirin, history of hypertension, and respiratory issues) may be relevant in the management of various medical conditions, they are not specifically associated with the precautions necessary for administering LMWH.
