The nurse is planning the home care of a client who is receiving a mydriatic medication. Which environment is best for this client?

A cool, humidified air.

A quiet, restful environment.

A dimly lit room.

A warm room temperature.

Answer and Explanation

The Correct Answer is C

Choice A reason: A cool, humidified air is not relevant for this client, as it does not affect the eyes or vision. A cool, humidified air may be beneficial for clients with respiratory conditions, such as asthma or bronchitis.

Choice B reason: A quiet, restful environment is not specific for this client, as it does not address the effects of mydriatic medication on the eyes or vision. A quiet, restful environment may be helpful for clients with stress, anxiety, or insomnia.

Choice C reason: A dimly lit room is the best environment for this client, as it reduces the glare and discomfort caused by mydriatic medication. Mydriatic medication is a type of eye drop that dilates the pupils and prevents them from constricting in response to light. This can improve the examination of the retina and optic nerve, but it also makes the eyes more sensitive to light and reduces the ability to focus on near objects.

Choice D reason: A warm room temperature is not necessary for this client, as it does not affect the eyes or vision. A warm room temperature may be comfortable for clients with cold intolerance, such as hypothyroidism or Raynaud's phenomenon.

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.

A. Stop the oral contraceptive immediately. B. Take the medications at least 12 hours apart. C. Use an additional form of contraception. D. Avoid prolonged exposure to direct sunlight.

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.
