A 54-year-old man has a myocardial infarction, resulting in left-sided heart failure.
The nurse caring for the man is most concerned that he will develop edema in what area of the body.
Peripheral.
Pulmonary.
Liver.
Abdominal.
The Correct Answer is B
Choice A rationale
Peripheral edema is more commonly associated with right-sided heart failure rather than left-sided. This is because right-sided heart failure leads to systemic venous congestion, causing fluid to accumulate in the peripheral tissues, particularly in the legs and ankles.
Choice B rationale
Pulmonary edema is a major concern in left-sided heart failure due to the inability of the left ventricle to effectively pump blood out to the systemic circulation. This results in blood backing up into the pulmonary veins, leading to fluid accumulation in the lungs.
Choice C rationale
Liver edema, or hepatomegaly, is more typically seen in right-sided heart failure, where the failure of the right ventricle causes blood to back up into the systemic circulation, affecting the liver and other organs.
Choice D rationale
Abdominal edema, or ascites, is also more associated with right-sided heart failure. This condition occurs due to increased pressure in the veins and capillaries, leading to fluid leakage into the abdominal cavity.

Correct Answer is D
Explanation
Choice A rationale
Antihistamines can enhance the sedative effects of cyclobenzaprine, increasing the risk of drowsiness and accidents. Patients should avoid combining these medications.
Choice B rationale
Antiemetics are not contraindicated with cyclobenzaprine, although they should be used cautiously due to potential interactions that can increase sedation.
Choice C rationale
Antibiotics do not generally interact significantly with cyclobenzaprine. There are no specific contraindications against their combined use.
Choice D rationale
Alcohol can significantly increase the sedative effects of cyclobenzaprine, leading to enhanced drowsiness, impaired motor functions, and an increased risk of accidents. Patients should avoid alcohol while taking this medication.
Correct Answer is C
Explanation
Choice A rationale
Anticholinergic drugs do not cause pupil restriction; they relax the muscles around the eye, leading to dilation.
Choice B rationale
Decreased lacrimal secretions are a secondary effect of anticholinergics and not their primary purpose in ophthalmology.
Choice C rationale
Anticholinergics cause pupil dilation (mydriasis) by relaxing the muscles that constrict the pupil, allowing for a better examination of the eye's interior.
Choice D rationale
Sedation is not a primary effect of anticholinergics used in ophthalmology.
