The nurse is caring for a client who is refusing to take their prescribed metformin (Glucophage). The nurse understands that the most common side effects of metformin are:

Choice A reason: Limit caffeine intake is not an instruction that the nurse should provide to the client who has asthma and a new prescription for inhaled fluticasone. Fluticasone is a medication that reduces inflammation and swelling in the airways, which can improve breathing and prevent asthma attacks. Fluticasone does not interact with caffeine or affect the heart rate or blood pressure. Caffeine is a stimulant that can cause nervousness, insomnia, or palpitations in some people, but it does not worsen asthma symptoms or interfere with fluticasone therapy. The nurse should advise the client to consume caffeine in moderation and avoid it before bedtime.

Choice B reason: Take the medication with meals is not an instruction that the nurse should provide to the client who has asthma and a new prescription for inhaled fluticasone. Fluticasone is a medication that reduces inflammation and swelling in the airways, which can improve breathing and prevent asthma attacks. Fluticasone is administered by inhalation, not by mouth, and it does not affect the digestion or absorption of food. The nurse should instruct the client to use the inhaler as prescribed, usually twice a day, regardless of the mealtimes.

Choice C reason: Rinse the mouth after administration is an instruction that the nurse should provide to the client who has asthma and a new prescription for inhaled fluticasone. Fluticasone is a medication that reduces inflammation and swelling in the airways, which can improve breathing and prevent asthma attacks. Fluticasone is a corticosteroid, which can cause side effects such as oral thrush, hoarseness, or sore throat if it remains in the mouth after inhalation. The nurse should instruct the client to rinse the mouth with water and spit it out after each dose of fluticasone to prevent these side effects. The nurse should also teach the client how to use the inhaler properly and check the inhaler technique regularly.

Choice D reason: Check the pulse after medication administration is not an instruction that the nurse should provide to the client who has asthma and a new prescription for inhaled fluticasone. Fluticasone is a medication that reduces inflammation and swelling in the airways, which can improve breathing and prevent asthma attacks. Fluticasone does not affect the heart rate or blood pressure, and it is not a rescue medication that should be used for acute asthma symptoms. The nurse should monitor the respiratory rate and the oxygen saturation of the client after administering fluticasone and advise the client to use a short acting bronchodilator, such as albuterol, for quick relief of wheezing or shortness of breath.

Choice A reason: This is correct. Blood pressure is the most important vital sign to monitor after giving sublingual nitroglycerin to a client with chest pain. Nitroglycerin is a medication that dilates the blood vessels and lowers the blood pressure. This can relieve the chest pain caused by angina, which is a condition where the heart muscle does not get enough oxygen due to narrowed or blocked arteries. However, if the blood pressure drops too low, the client may experience dizziness, fainting, or shock. Therefore, the nurse should check the blood pressure before and after giving nitroglycerin and report any significant changes to the doctor.

Choice B reason: This is incorrect. Blood glucose levels are not directly affected by sublingual nitroglycerin. However, some clients with chest pain may also have diabetes, which is a risk factor for heart disease. Diabetes is a condition where the body cannot regulate the amount of sugar in the blood. High or low blood sugar levels can cause symptoms such as thirst, hunger, fatigue, blurred vision, or confusion. Therefore, the nurse should check the blood glucose levels of clients with diabetes and follow the doctor's orders for managing their blood sugar.

Choice C reason: This is incorrect. Body temperature is not directly affected by sublingual nitroglycerin. However, some clients with chest pain may also have a fever, which is a sign of infection or inflammation. Fever is a condition where the body's temperature rises above the normal range. Fever can cause symptoms such as sweating, chills, headache, or muscle ache. Therefore, the nurse should check the body temperature of clients with fever and follow the doctor's orders for treating their infection or inflammation.

Choice D reason: This is incorrect. Respiratory rate is not directly affected by sublingual nitroglycerin. However, some clients with chest pain may also have difficulty breathing, which is a sign of heart failure or lung disease. Difficulty breathing is a condition where the client cannot get enough air into or out of the lungs. Difficulty breathing can cause symptoms such as coughing, wheezing, or gasping. Therefore, the nurse should check the respiratory rate of clients with difficulty breathing and follow the doctor's orders for improving their oxygenation.
