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 ["1"]
Explanation
To determine the number of tablets the nurse should administer for each dose, we can use the following calculation:
75 mg/day ÷ 2 doses = 37.5 mg/dose
Since 37.5 mg tablets are available, the nurse should administer 1 tablet with each dose.
Correct Answer is C
Explanation
Choice A reason: This is incorrect. INR level is a measure of blood clotting time and is not directly affected by digoxin. It is more relevant for patients who are taking anticoagulants, such as warfarin.
Choice B reason: This is incorrect. Temperature is not a priority assessment for a patient receiving digoxin. It may indicate an infection or inflammation, but it is not related to the action or toxicity of digoxin.
Choice C reason: This is correct. Apical heart rate is the priority assessment for a patient receiving digoxin. Digoxin is a cardiac glycoside that increases the force and efficiency of the heart contractions, but also slows down the heart rate. The nurse should monitor the apical pulse for one full minute before administering digoxin and withhold the dose if the pulse is below 60 beats per minute for adults or below the age-specific normal range for children. A low or irregular pulse may indicate digoxin toxicity, which can be life-threatening.
Choice D reason: This is incorrect. Blood pressure is not a priority assessment for a patient receiving digoxin. Digoxin does not have a direct effect on blood pressure, although it may improve the cardiac output and reduce the fluid retention in patients with heart failure. Blood pressure should be monitored regularly, but it is not as critical as the apical heart rate.
