A client who has Graves’ disease is prescribed methimazole.
Which of the following effects should the nurse expect to see after the client has taken the medication for 2 months?

Lisinopril is an angiotensin converting enzyme (ACE) inhibitor that is used to treat high blood pressure and heart failure. It works by relaxing the blood vessels and increasing the supply of blood and oxygen to the heart. However, one of the common side effects of lisinopril is hypotension, which means low blood pressure. Hypotension can cause dizziness, faintness, or lightheadedness when getting up suddenly from a lying or sitting position. Therefore, the nurse should monitor the client’s blood pressure when administering lisinopril and report any signs of hypotension to the doctor.

Choice A is wrong because tinnitus, which means ringing or buzzing in the ears, is not a common or serious side effect of lisinopril.

Tinnitus can be caused by other factors such as ear infections, loud noises, or medications such as aspirin or antibiotics.

Choice C is wrong because hypokalemia, which means low potassium levels in the blood, is not a common or serious side effect of lisinopril. In fact, lisinopril can cause hyperkalemia, which means high potassium levels in the blood, especially in patients with kidney problems or diabetes. Hyperkalemia can cause irregular heartbeats, muscle weakness, or numbness. Therefore, the nurse should monitor the client’s potassium levels when administering lisinopril and avoid giving potassium supplements or salt substitutes that contain potassium.

Choice D is wrong because bradycardia, which means slow heart rate, is not a common or serious side effect of lisinopril.

Lisinopril does not affect the heart rate directly, but it can lower the blood pressure and improve the heart function.

Bradycardia can be caused by other factors such as heart block, sinus node dysfunction, or medications such as beta blockers or calcium channel blockers.

Pruritus is a common adverse effect of morphine administered via continuous epidural infusion. It is caused by the release of histamine from mast cells in the skin. Pruritus can be treated with antihistamines or opioid antagonists. Choice A is wrong because gastric bleeding is not a common adverse effect of morphine administered via continuous epidural infusion.

Gastric bleeding can occur due to peptic ulcer disease, nonsteroidal anti inflammatory drugs (NSAIDs), or anticoagulants.

Choice C is wrong because cough is not a common adverse effect of morphine administered via continuous epidural infusion.

Cough can be caused by respiratory infections, asthma, or chronic obstructive pulmonary disease (COPD).

Choice D is wrong because tachypnea is not a common adverse effect of morphine administered via continuous epidural infusion.

Tachypnea can be caused by hypoxia, anxiety, pain, or fever. Morphine can cause respiratory depression, which is characterized by bradypnea, not tachypnea.
