When teaching a patient who is taking thiazide diuretics, the nurse will encourage the patient to increase the intake of which electrolyte?
Potassium
Magnesium
Calcium
Sodium
The Correct Answer is A
A. Thiazide diuretics can lead to hypokalemia (low potassium levels) as they increase potassium excretion in the urine. Therefore, increasing potassium intake is crucial to prevent hypokalemia and its associated complications, such as arrhythmias.
B. While magnesium levels can also be affected by diuretics, it's not as significant as potassium depletion.
C. Thiazide diuretics can actually increase calcium reabsorption in the kidneys, leading to potential hypercalcemia. Therefore, increasing calcium intake is not recommended.
D. Thiazide diuretics are used to reduce sodium and water retention, so increasing sodium intake would counteract their effect.

Correct Answer is ["5.3"]
Explanation
1 kilogram equals 2.2 pounds.
The preschooler weighs 29 pounds, which is approximately 13.18 kilograms (29/2.2). The order is for 40 mg/kg/day
13.18 kg * 40 mg/kg = 527.2 mg/day.
Since the medication is to be administered every 12 hours, divide this daily dosage by 2 to get the per dose amount: 527.2 mg/day / 2 = 263.6 mg/dose.
Now, using the concentration of the elixir, which is 250 mg/5 mL, set up a proportion to find out how many milliliters are needed for the prescribed dose: 250 mg : 5 mL = 263.6 mg : X mL.
Solving for X gives us (263.6 mg * 5 mL) / 250 mg = 5.272 mL per dose.
Rounding to the nearest tenth, the nurse should administer 5.3 mL per dose.
Correct Answer is B
Explanation
A. Apnea refers to a temporary cessation of breathing. If a patient is experiencing apnea, there would be a complete stop in respiratory activity, which does not apply to a respiratory rate of 36 breaths per minute.
B. Tachypnea is defined as an increased respiratory rate, typically greater than 20 breaths per minute in adults. A respiratory rate of 36 breaths per minute falls well within this range, indicating that the patient is experiencing tachypnea.
C. Bradypnea refers to a decreased respiratory rate, usually defined as fewer than 12 breaths per minute. Since the patient’s rate is 36 breaths per minute, this option does not apply.
D. Orthopnea refers to difficulty breathing when lying flat and is not specifically related to the respiratory rate itself. It usually describes a positional dyspnea rather than a numerical measurement of breathing.
