A nurse is caring for a client who has leukemia. Which of the following findings is the highest priority for the nurse to report to the provider?

Choice A reason: Taking the medication right before eating breakfast is not an appropriate instruction, as it can reduce the absorption and effectiveness of alendronate, which is a bisphosphonate drug that inhibits bone resorption and increases bone density. The client should take the medication at least 30 min before eating or drinking anything other than water.

Choice B reason: Drinking milk with the medication is not an appropriate instruction, as it can interfere with the absorption and effectiveness of alendronate, which can bind to calcium and other minerals and form insoluble complexes that are excreted in feces. The client should avoid consuming dairy products or supplements that contain calcium, iron, magnesium, or aluminum for at least 30 min after taking the medication.

Choice C reason: Staying upright for 30 to 60 min after taking the medication is an appropriate instruction, as it can prevent esophageal irritation or ulceration that can be caused by alendronate, which can be corrosive to the mucosa if it remains in contact with it for too long. The client should not lie down or bend over until after their first food of the day.

Choice D reason: Chewing the tablets thoroughly is not an appropriate instruction, as it can increase the risk of esophageal irritation or ulceration that can be caused by alendronate, which can be abrasive to the mucosa if it is not swallowed whole with a full glass of water. The client should not crush, break, or dissolve the tablets in any liquid.

Choice A reason: BUN or blood urea nitrogen 30 mg/dL is above the normal range of 10 to 20 mg/dL and indicates renal impairment or dehydration, which can be caused by contrast dye used during coronary angiography or blood loss during or after the procedure. The nurse should report this value to the provider and monitor the client for signs of acute kidney injury, such as oliguria, edema, or electrolyte imbalances.

Choice B reason: Sinus rhythm 95/min on a cardiac monitor is within the normal range of 60 to 100/min and does not indicate any cardiac arrhythmia or ischemia.

Choice C reason: Respiratory rate 12/min is within the normal range of 12 to 20/min and does not indicate any respiratory distress or hypoxia.

Choice D reason: PTT or partial thromboplastin time 25 seconds is within the normal range of 25 to 35 seconds and does not indicate any bleeding disorder or anticoagulant therapy.
