A client has the feeling of having “chest tightness” while experiencing “cold-like” symptoms. Her cough is nonproductive. Her physician prescribed guaifenesin (Mucinex) to help with secretions.
When teaching about this medication, what should the nurse instruct? (Select all that apply)
“Drink extra water while taking this medication.”
“Monitor urine output closely.”
“Take it with an oral antihistamine for better effectiveness.”
“Avoid driving or using heavy machinery while on this medication.”
Correct Answer : A
A. “Drink extra water while taking this medication.”
This is correct. Guaifenesin is an expectorant that works by thinning and loosening mucus in the airways. Drinking extra water helps to enhance its effectiveness by keeping the patient well-hydrated.
B. “Monitor urine output closely.”
Monitoring urine output is not typically necessary with guaifenesin. It does not have a diuretic effect, and excessive monitoring of urine output may not be relevant in this context.
C. “Take it with an oral antihistamine for better effectiveness.”
Guaifenesin is often used in combination with other medications, but taking it with an oral antihistamine is not a standard recommendation. The combination should be based on the specific guidance of the healthcare provider.
D. “Avoid driving or using heavy machinery while on this medication.”
Guaifenesin does not typically cause sedation or impairment, so there is generally no need to avoid driving or using heavy machinery. This instruction may not be necessary for this medication.

Correct Answer is D
Explanation
Choice A rationale: Incorrect. Methotrexate is a chemotherapy drug and an immunosuppressant but not an antibiotic. It inhibits the metabolism of folic acid, which is necessary for cell replication, but it does not have antibiotic properties.
Choice B rationale: Incorrect. Antiestrogens are a class of drugs used to treat hormone-sensitive cancers like breast cancer by blocking the effects of estrogen. They are not antibiotics and do not have antimicrobial properties.
Choice C rationale: Incorrect. Corticosteroids are used in cancer treatment primarily to reduce inflammation and manage side effects of chemotherapy, such as nausea and allergic reactions. They have immunosuppressive properties but are not antibiotics.
Choice D rationale: Correct. Doxorubicin (Doxil) is an antitumor drug that also has antibiotic properties. It belongs to the anthracycline class of chemotherapy drugs and works by intercalating DNA, disrupting the replication and transcription processes, leading to cell death. Doxorubicin was originally derived from the bacterium Streptomyces peucetius, which imparts its antibiotic properties.

A. Chest X-rays
Chest X-rays are imaging tests that provide detailed pictures of the inside of the chest, including the heart, lungs, and other structures. They are noninvasive as they do not involve any penetration or insertion into the body.
B. Echocardiogram
An echocardiogram is a noninvasive test that uses sound waves to create images of the heart. It provides information about the structure and function of the heart without the need for invasive procedures.
C. Pulmonary function tests
Pulmonary function tests (PFTs) are noninvasive tests that assess the function of the lungs. They include various breathing exercises and measurements to evaluate lung capacity and respiratory function.
D. Cardiac catheterization
Cardiac catheterization is an invasive procedure that involves the insertion of a catheter into the heart. It is not considered noninvasive.
