A nurse is obtaining a medication history from a client who reports taking 1 oz of magnesium hydroxide daily as a laxative. The nurse should identify that this dose equates to how many mL?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A reason: This is incorrect because fentanyl 25 mcg/hr transdermal patch is a common and appropriate dose for chronic pain management. Fentanyl is a potent opioid analgesic that delivers a steady amount of medication through the skin over 72 hours.

Choice B reason: This is incorrect because meloxicam 15 mg PO daily is a standard and safe dose for treating inflammation and pain caused by arthritis. Meloxicam is a nonsteroidal anti-inflammatory drug (NSAID) that reduces the production of prostaglandins, which are involved in inflammation.

Choice C reason: This is correct because regular insulin 8 units subcutaneous before meals is a vague and potentially dangerous prescription. Regular insulin is a short-acting insulin that lowers blood glucose levels by facilitating the uptake of glucose into the cells. The dose of insulin should be individualized based on the client's blood glucose level, carbohydrate intake, and activity level. The nurse should contact the provider for clarification on how to adjust the dose according to the client's needs.

Choice D reason: This is incorrect because docusate sodium 200 mg PO at bedtime is a usual and effective dose for preventing constipation. Docusate sodium is a stool softener that works by increasing the amount of water in the stool, making it easier to pass.

Choice A reason: Atenolol is a beta blocker that lowers blood pressure and heart rate. The nurse should hold atenolol for this client because the client's heart rate is already low (52 beats per minute), and giving atenolol could cause bradycardia (slow heart rate), which can lead to dizziness, fainting, or heart failure. The nurse should notify the provider and monitor the client's vital signs and cardiac rhythm.

Choice B reason: Captopril is an ACE inhibitor that lowers blood pressure and prevents kidney damage. The nurse should not hold captopril for this client because the client's blood pressure is still high (138/90 mmHg), and captopril could help lower it to the target range. The nurse should administer captopril as prescribed and monitor the client's blood pressure and renal function.

Choice C reason: Warfarin is an anticoagulant that prevents blood clots and reduces the risk of stroke. The nurse should not hold warfarin for this client because the client's INR (a measure of blood clotting time) is within the therapeutic range (2.0 to 3.0), and warfarin could help prevent post-operative complications such as deep vein thrombosis or pulmonary embolism. The nurse should administer warfarin as prescribed and monitor the client's INR and bleeding signs.

Choice D reason: Glipizide is not a medication for this client. Glipizide is an oral hypoglycemic agent that lowers blood sugar levels in people with diabetes. This client does not have diabetes and does not need glipizide. The nurse should check the medication order and the client's medical history and clarify any discrepancies with the provider.
