Question 1 of 9
A client has a prescription to take guaifenesin (Humibid) every 4 hours, as needed. The nurse determines that the client understands the most effective use of this medication if the client states that he or she will:
Correct Answer: B
Rationale: Guaifenesin is an expectorant used to help loosen mucus and make coughs more productive. Taking it with a full glass of water helps decrease the viscosity of secretions, making it easier to expel mucus from the respiratory tract. It is important not to crush sustained-release tablets, as this can alter the intended release of the medication and lead to potential adverse effects.
Question 2 of 9
A client who received a kidney transplant is taking azathioprine (Imuran), and the nurse provides instructions about the medication. Which statement by the client indicates a need for further instructions?
Correct Answer: B
Rationale: Azathioprine is an immunosuppressant taken for life. Discontinuing the medication after 14 days is incorrect.
Question 3 of 9
The nurse provides medication instructions to an older hypertensive client who is taking 20 mg of lisinopril (Prinivil, Zestril) orally daily. The nurse evaluates the need for further teaching when the client states which of the following?
Correct Answer: A
Rationale: Lisinopril should be taken daily as prescribed and not skipped. Skipping doses can lead to ineffective treatment.
Question 4 of 9
A client who has been newly diagnosed with diabetes mellitus has been stabilized with daily insulin injections. Which information should the nurse teach when carrying out plans for discharge?
Correct Answer: B
Rationale: When a client is stabilized with daily insulin injections, it is crucial to rotate the injection sites systematically. This practice helps prevent the development of lipodystrophy, which can affect insulin absorption and lead to inconsistent glucose control. Additionally, rotating sites minimizes discomfort and tissue damage, ensuring optimal insulin delivery and effectiveness.
Question 5 of 9
Which statement by the client indicates a need for further teaching about the use of metoprolol (Lopressor)?
Correct Answer: D
Rationale: The correct answer is D because taking metoprolol (Lopressor) at bedtime is not specifically recommended. Metoprolol should be taken with food to enhance absorption. It is crucial for the client not to stop taking the medication abruptly to prevent rebound hypertension or other adverse effects. Additionally, monitoring the pulse before taking metoprolol is important for assessing its effect on heart rate.
Question 6 of 9
A client who had a kidney transplant is receiving therapy with cyclosporine (Sandimmune). Which statement by the client indicates a need for further instruction?
Correct Answer: A
Rationale: The correct answer is A. Cyclosporine is an immunosuppressant that can reduce the effectiveness of vaccines. Clients should avoid vaccinations without consulting their health care provider to prevent potential complications or reduced efficacy of the vaccines.
Question 7 of 9
A client has been started on long-term therapy with rifampin (Rifadin). A nurse teaches the client that the medication:
Correct Answer: C
Rationale: Rifampin causes orange-red discoloration of body secretions, including sweat, tears, urine, and feces. It can also permanently stain soft contact lenses. It is essential to take rifampin exactly as directed and not discontinue it without consulting the healthcare provider.
Question 8 of 9
Tamoxifen is prescribed for the client with metastatic breast carcinoma. The nurse understands that the primary action of this medication is to:
Correct Answer: D
Rationale: The primary action of tamoxifen, an antineoplastic medication used in metastatic breast carcinoma, is to compete with estradiol for binding to estrogen receptors in tissues with high receptor concentrations. By doing so, tamoxifen reduces DNA synthesis and estrogen response, leading to its therapeutic effect in inhibiting the growth of estrogen-sensitive breast cancer cells.
Question 9 of 9
Isotretinoin is prescribed for a client with severe acne. Before the administration of this medication, the nurse anticipates that which laboratory test will be prescribed?
Correct Answer: B
Rationale: Before administering Isotretinoin, it is important to check the client's triglyceride levels. Isotretinoin is known to elevate triglyceride levels, hence monitoring them before and periodically during treatment is essential to prevent potential adverse effects.
