The nurse is providing medication teaching to a client prescribed lisinopril 10 mg PO daily. Which side effect of the medication will the nurse explain to the client is most common?

Choice A reason: Limiting the intake of citrus juices is not related to the teaching about hydrochlorothiazide. Citrus juices are rich in vitamin C, which has no significant interaction with hydrochlorothiazide. The client does not need to avoid or limit citrus juices unless they have other medical conditions that require dietary restrictions.

Choice B reason: Eating bananas daily to lower the potassium level is a wrong statement. Bananas are high in potassium, which is a mineral that hydrochlorothiazide can deplete from the body. The client may need to increase their potassium intake or take a potassium supplement to prevent hypokalemia, a condition of low potassium level that can cause muscle weakness, cramps, and arrhythmias.

Choice C reason: Taking the pill each day in the morning is the correct statement. Hydrochlorothiazide is a diuretic that increases the urine output and reduces the blood volume and pressure. The client should take the pill in the morning to avoid nocturia, which is frequent urination at night that can disrupt the sleep quality and increase the risk of falls.

Choice D reason: Taking the pill each day after dinner is not the best statement. Hydrochlorothiazide can cause diuresis, which is increased urine production and excretion. Taking the pill after dinner can lead to nocturia, which is frequent urination at night that can interfere with the sleep cycle and cause fatigue and irritability. The client should take the pill in the morning to prevent nocturia and its complications.

Choice A reason: This is not the best answer. Respiratory rate and depth can indicate the client's oxygenation and ventilation, but not necessarily their fluid status. The client may have normal or increased respiratory rate and depth due to dehydration, acidosis, or anxiety, but this does not reflect their fluid volume or distribution. The nurse should monitor the client's respiratory rate and depth, but also assess other parameters of fluid status.

Choice B reason: This is not the best answer. Rectal temperature can indicate the client's core body temperature, but not necessarily their fluid status. The client may have normal or elevated rectal temperature due to infection, inflammation, or dehydration, but this does not reflect their fluid volume or distribution. The nurse should monitor the client's rectal temperature, but also assess other parameters of fluid status.

Choice C reason: This is the best answer. Blood pressure lying, sitting and standing can indicate the client's fluid status and vascular tone. The client may have low blood pressure due to fluid loss, hypovolemia, or vasodilation, and this can cause orthostatic hypotension, which is a drop in blood pressure when changing positions. The nurse should measure the client's blood pressure in different positions and observe for signs of orthostatic hypotension, such as dizziness, fainting, or blurred vision.

Choice D reason: This is not the best answer. Pulse oximetry reading at rest can indicate the client's oxygen saturation, but not necessarily their fluid status. The client may have normal or decreased pulse oximetry reading due to hypoxia, anemia, or poor peripheral perfusion, but this does not reflect their fluid volume or distribution. The nurse should monitor the client's pulse oximetry reading, but also assess other parameters of fluid status.
