The nurse administers risedronate to a client with osteoporosis at 0700. The client asks for a glass of milk to drink with the medication. Which action should the nurse take?
Instruct the client that it is necessary to take nothing but water with the medication.
Assign an unlicensed assistive personnel (UAP) to bring the client a glass of low fat milk.
Withhold the medication until the client's breakfast tray is available on the unit.
Consult with a pharmacist about scheduling the dose one hour after the client eats.
The Correct Answer is A
Choice A reason: Risedronate is a bisphosphonate that is used to treat osteoporosis by inhibiting bone resorption. It should be taken on an empty stomach with a full glass of water at least 30 minutes before any other food, beverage, or medication. This is because food, milk, and antacids can interfere with the absorption of risedronate and reduce its effectiveness.
Choice B reason: Milk contains calcium, which can bind to risedronate and prevent its absorption. Therefore, the client should not drink milk with or within 2 hours of taking risedronate.
Choice C reason: Withholding the medication until the client's breakfast tray is available is not appropriate, as it would delay the administration of risedronate and disrupt the dosing schedule. The client should take risedronate as soon as possible after waking up and before eating anything.
Choice D reason: Consulting with a pharmacist about scheduling the dose one hour after the client eats is not necessary, as risedronate should be taken at least 30 minutes before any food or beverage. Taking risedronate one hour after eating may not ensure adequate absorption of the drug.

Correct Answer is C
Explanation
Choice A reason: Stopping the oral contraceptive immediately is not necessary and may increase the risk of unintended pregnancy. Erythromycin can reduce the effectiveness of oral contraceptives by interfering with their metabolism, but it does not make them completely ineffective.
Choice B reason: Taking the medications at least 12 hours apart is not sufficient to prevent the interaction between erythromycin and oral contraceptives. The interaction can occur regardless of the timing of the doses.
Choice C reason: Using an additional form of contraception is the best instruction for the client who is taking an oral contraceptive and erythromycin. This can prevent pregnancy in case the oral contraceptive fails due to the interaction with erythromycin. The additional form of contraception should be non-hormonal, such as a barrier method or a copper intrauterine device.
Choice D reason: Avoiding prolonged exposure to direct sunlight is a good advice for anyone taking erythromycin, as it can cause photosensitivity and increase the risk of sunburn. However, this is not related to the interaction with oral contraceptives and does not affect their efficacy.
Correct Answer is C
Explanation
Choice B reason: Epoetin alfa is a synthetic form of erythropoietin, a hormone that stimulates the production of red blood cells (RBCs) in the bone marrow. Epoetin alfa is used to treat anemia, or low RBC count, which can be caused by CKD, chemotherapy, HIV infection, or other conditions. Anemia can cause symptoms such as weakness, fatigue, shortness of breath, pale skin, and chest pain. Hemoglobin is the protein in RBCs that carries oxygen throughout the body. The normal range of hemoglobin for males is 14 to 18 g/dL (8.7 to 11.2 mmol/L). Therefore, an increase in hemoglobin from below normal to within normal indicates that epoetin alfa has been effective in increasing RBC production and improving oxygen delivery. The nurse should monitor the client's hemoglobin level regularly and adjust the dose of epoetin alfa as needed.
Choice A reason:While iron therapy supports the effectiveness of epoetin alfa by providing the necessary substrate for erythropoiesis, tolerating iron therapy is not an indicator of epoetin alfa's efficacy.
Choice C reason: Epoetin alfa is used to treat anemia associated with chronic kidney disease (CKD) by stimulating erythropoiesis (red blood cell production). The primary measure of its effectiveness is an increase in hemoglobin (Hgb) levels toward the target range. The hemoglobin level increasing to 12 g/dL (7.45 mmol/L) reflects a significant improvement from an anemic state and is within the target range for patients receiving epoetin alfa therapy (generally 10–12 g/dL). This is the most objective and definitive indicator of the medication's effectiveness.
Choice D reason: Taking concurrent iron therapy without adverse effects is not a finding that best indicates that the medication is effective, but rather a preventive measure that can reduce the risk of iron deficiency and improve the efficacy of epoetin alfa. Iron therapy refers to taking oral or intravenous iron supplements to increase iron levels in the blood. Iron therapy can cause side effects such as nausea, vomiting, constipation, diarrhea, dark stools, metallic taste, or allergic reactions. The nurse should instruct the client on how to take iron therapy safely and monitor for any adverse effects.
