Which of the following clients would the nurse question an order for labetalol 50 mg PO?
28 year old woman with pregnancy-induced hypertension
Pizza delivery driver with 5 year history of smoking
Client with a history of uncontrolled asthma
55 year old male who had a myocardial infarction 2 days ago
The Correct Answer is C
Choice A reason: This is incorrect because labetalol is a safe and effective medication for treating hypertension in pregnancy. Labetalol is a beta-blocker that lowers blood pressure by reducing the heart rate and the force of contraction. It does not affect the blood flow to the placenta or the fetus.
Choice B reason: This is incorrect because labetalol is not contraindicated for smokers. However, smoking is a risk factor for cardiovascular disease and should be discouraged by the nurse. Smoking can increase blood pressure, heart rate, and the risk of blood clots.
Choice C reason: This is correct because labetalol is contraindicated for clients with a history of uncontrolled asthma. Labetalol is a non-selective beta-blocker that can block the beta-2 receptors in the lungs and cause bronchoconstriction. This can worsen asthma symptoms and trigger an asthma attack.
Choice D reason: This is incorrect because labetalol is a suitable medication for clients who had a myocardial infarction. Labetalol can prevent further damage to the heart muscle by reducing the oxygen demand and the workload of the heart. It can also prevent arrhythmias and angina.

Correct Answer is ["18"]
Explanation
To calculate the dose of methylprednisolone sodium succinate that the nurse should administer, we can follow these steps:
Convert the client's weight from pounds to kilograms:
169 lb ÷ 2.2 = 76.82 kg (rounded to two decimal places)
Calculate the dose of methylprednisolone sodium succinate:
30 mg/kg × 76.82 kg = 2,304.6 mg
Determine the volume of methylprednisolone sodium succinate needed using the available concentration:
2,304.6 mg ÷ 125 mg/mL = 18.437 mL
Rounding to the nearest whole number, the nurse should administer 18 mL of methylprednisolone sodium succinate via intermittent IV bolus.
Correct Answer is C
Explanation
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.
