The healthcare provider prescribes the anticoagulant heparin for a client with a pulmonary embolism. Before initiating the medication, the nurse should ensure that which drug is readily available in case of heparin overdose?

A) Avoid the intake of dairy products while using the medication: There is no specific requirement to avoid dairy products when using bulk-forming laxatives. The primary concern with bulk-forming laxatives is to ensure they are taken with adequate fluids.
B) Take the medication one hour after meals and other medications: Bulk-forming laxatives should be taken with a meal or at a different time from other medications to prevent interactions, but the key aspect is to follow the medication with sufficient fluids rather than timing relative to meals.
C) Remain upright for thirty minutes following drug administration: While remaining upright can help prevent potential esophageal irritation, it is not the primary instruction for bulk-forming laxatives. The more critical instruction is related to fluid intake to ensure effectiveness and prevent complications.
D) Follow medication administration with an additional glass of water: Bulk-forming laxatives require adequate fluid intake to function properly. Following the medication with an additional glass of water helps the laxative form a gel-like substance in the intestines, which aids in bowel movement and prevents potential complications like obstruction.

A) Protect the skin from sunlight while taking the drug: Tetracycline is known to increase sensitivity to sunlight, leading to a higher risk of sunburn and skin reactions. Advising clients to protect their skin from sun exposure and to use sunscreen is essential to prevent these adverse effects. This precaution helps mitigate the risk of photosensitivity reactions that are commonly associated with tetracycline use.
B) Take with orange juice to enhance gastrointestinal (GI) absorption: Tetracycline should not be taken with dairy products or antacids, as they can bind with the medication and reduce its absorption. While orange juice can enhance absorption, this is not a standard recommendation for tetracycline. Instead, it is generally advised to take tetracycline with water and avoid substances that could interfere with its absorption.
C) Return to the clinic weekly to obtain serum drug levels: Tetracycline typically does not require regular monitoring of serum drug levels, as it does not have a narrow therapeutic index like some other drugs. Instead, patients are generally advised on how to manage side effects and adherence to the medication regimen, rather than frequent clinic visits for drug level monitoring.
D) Take with milk or antacids to prevent gastrointestinal (GI) irritation: Milk and antacids should be avoided when taking tetracycline because they can bind to the medication and significantly reduce its effectiveness. This instruction could lead to decreased therapeutic efficacy and should be avoided. Tetracycline should be taken on an empty stomach to ensure optimal absorption, avoiding interactions with these substances.
