A nurse is admitting a client who has hepatitis C. Which of the following precautions should the nurse implement?

Choice A reason : Headaches are a common side effect of nitroglycerin due to its vasodilatory effects, which can cause blood vessels to expand, leading to headaches. Patients should be informed that this is a common reaction and can be managed with over-the-counter pain relievers if necessary¹²³⁴.

Choice B reason : A headache is not typically an indication of an allergy to nitroglycerin. Allergic reactions would more likely present with symptoms such as rash, itching, or difficulty breathing.

Choice C reason : While anxiety can cause headaches, in this context, the headache is more likely a direct side effect of the nitroglycerin, especially since it occurred after taking the medication and the chest pain was relieved.

Choice D reason : Tolerance to medication refers to a reduced response to a drug over time, requiring higher doses to achieve the same effect. A headache after taking nitroglycerin does not indicate tolerance; it is a known side effect of the drug.

Choice A reason : Fibromyalgia can indeed be associated with migraine headaches. Many individuals with fibromyalgia report experiencing headaches, and migraines are a common comorbidity. The exact link between fibromyalgia and migraines is not fully understood, but it is believed that the same abnormalities in neurotransmitter levels that contribute to fibromyalgia pain may also predispose individuals to migraines¹².

Choice B reason : The statement "Fibromyalgia causes joint inflammation" is incorrect and indicates a need for further teaching. Fibromyalgia does not cause inflammation within the joints. It is characterized by widespread musculoskeletal pain, fatigue, and tenderness in specific areas, but it does not involve the type of joint inflammation seen in conditions like rheumatoid arthritis¹². This misconception may arise because the symptoms can be similar to those of arthritic conditions, but the underlying mechanisms are different.

Choice C reason : Fibromyalgia may indeed cause chest pain, which is often referred to as costochondritis when it involves the cartilage of the rib cage. This chest pain can mimic that of a heart attack or other heart conditions, but it is actually a common symptom of fibromyalgia and is related to the tender points in the chest area¹².

Choice D reason : It is true that fibromyalgia symptoms may worsen depending on the weather. Many patients report that their symptoms flare up in response to changes in weather, temperature, and humidity. However, the reasons for this sensitivity are not entirely clear, and research on the subject has produced mixed results¹².
