The nurse is teaching a client with hypertension about the prescribed hydrochlorothiazide 10 mg PO daily. Which statement, made by the client, would indicate that the teaching has been effective? "I will:
A. Limit my intake of citrus juices
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.
B. Eat bananas daily to lower my potassium level
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.
C. Take my pill each day in the morning
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.
D. Take my pill each day after dinner
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.

Similar Questions
The nurse administers atenolol 50 mg PO bid to a client who has coronary artery disease. The nurse understands that the therapeutic effect of this medication for this client is to:
A. Decrease the incidence of tachycardia
Decreasing the incidence of tachycardia is not the main therapeutic effect of atenolol for coronary artery disease. Atenolol is a beta-blocker that lowers the heart rate, but this is not the primary goal of therapy for coronary artery disease. Coronary artery disease is caused by atherosclerosis, which is the buildup of plaque in the arteries that supply the heart. This reduces the blood flow and oxygen to the heart muscle and causes angina, or chest pain.
B. Dilate the coronary arteries
Dilating the coronary arteries is not the therapeutic effect of atenolol for coronary artery disease. Atenolol does not directly affect the diameter of the coronary arteries. It works by blocking the beta receptors in the heart and reducing the response to adrenaline and other stress hormones. This lowers the blood pressure and the oxygen demand of the heart.
C. Decrease cardiac workload
This is the correct answer. Decreasing cardiac workload is the therapeutic effect of atenolol for coronary artery disease. Atenolol reduces the contractility and the excitability of the heart muscle, which lowers the force and the frequency of the heartbeats. This decreases the amount of work that the heart has to do and the amount of oxygen that it needs. This helps prevent or relieve anginal attacks and improve the quality of life of the client.
D. Increase the strength of myocardial contraction
Increasing the strength of myocardial contraction is not the therapeutic effect of atenolol for coronary artery disease. Atenolol does not increase the strength of myocardial contraction, but rather decreases it. Increasing the strength of myocardial contraction would increase the oxygen demand of the heart and worsen the angina. Atenolol aims to reduce the oxygen demand of the heart and improve the blood supply to the heart.

The nurse obtains the following arterial blood gas results on a client: pH 7.2, PaO2 88 mmHg, PaCO2 40 mmHg, HCO3 19 mEq/L. Which acid-base imbalance is the client experiencing?
A. Respiratory alkalosis
Respiratory alkalosis is not the correct answer. Respiratory alkalosis is a condition where the blood pH is high (above 7.45) due to low carbon dioxide levels (below 35 mmHg) caused by hyperventilation. The client's blood pH is low (7.2) and the carbon dioxide level is normal (40 mmHg), which does not indicate respiratory alkalosis.
B. Metabolic alkalosis
Metabolic alkalosis is not the correct answer. Metabolic alkalosis is a condition where the blood pH is high (above 7.45) due to high bicarbonate levels (above 26 mEq/L) caused by excessive loss of acids or intake of alkali. The client's blood pH is low (7.2) and the bicarbonate level is low (19 mEq/L), which does not indicate metabolic alkalosis.
C. Respiratory acidosis
Respiratory acidosis is not the correct answer. Respiratory acidosis is a condition where the blood pH is low (below 7.35) due to high carbon dioxide levels (above 45 mmHg) caused by hypoventilation. The client's blood pH is low (7.2) but the carbon dioxide level is normal (40 mmHg), which does not indicate respiratory acidosis.
D. Metabolic acidosis
This is the correct answer. Metabolic acidosis is a condition where the blood pH is low (below 7.35) due to low bicarbonate levels (below 22 mEq/L) caused by excessive production or intake of acids or loss of alkali. The client's blood pH is low (7.2) and the bicarbonate level is low (19 mEq/L), which indicates metabolic acidosis.

The nurse instructs a client diagnosed with hypertension and coronary artery disease who has been given a new prescription for carvedilol 6.25 mg PO bid to:
A. Increase the intake of dietary fiber
Increasing the intake of dietary fiber is not related to the instruction for carvedilol. Dietary fiber is beneficial for lowering cholesterol and blood sugar levels, but it does not affect the action or side effects of carvedilol. The client should follow a balanced diet that is low in sodium, fat, and cholesterol.
B. Change from a lying to sitting position slowly
This is the correct answer. Changing from a lying to sitting position slowly is an important instruction for carvedilol. Carvedilol is a beta-blocker that lowers the blood pressure and the heart rate. It can cause orthostatic hypotension, which is a sudden drop in blood pressure when changing positions. This can lead to dizziness, fainting, or falls. The client should change positions gradually and avoid sudden movements.
C. Expect weight gain of 6-8 pounds
Expecting weight gain of 6-8 pounds is not an instruction for carvedilol. Weight gain is not a common or expected side effect of carvedilol. It can indicate fluid retention, which can worsen the heart condition and the blood pressure. The client should monitor their weight regularly and report any significant changes to the health care provider.
D. Take the medication after eating breakfast
Taking the medication after eating breakfast is not an instruction for carvedilol. Carvedilol can be taken with or without food, depending on the client's preference and tolerance. The important thing is to take the medication at the same time every day and not to skip or double the doses.
