A client is taking furosemide (Lasix) for management of mild hypertension. The nurse knows to assess laboratory results for a side effect of this diuretic. Select the lab value that matches a common side effect of this medication.
A serum potassium level of 5.6 mEq/L
A serum sodium level of 142 mEq/L
A serum sodium level of 138 mEq/L
A serum potassium level of 2.8 mEq/L
The Correct Answer is D
Choice A reason: A serum potassium level of 5.6 mEq/L is not a common side effect of furosemide, but of hyperkalemia. Hyperkalemia is a condition where the blood potassium level is too high. It can cause muscle weakness, irregular heartbeat, and cardiac arrest. Furosemide is a loop diuretic that increases the urinary excretion of water, sodium, chloride, and potassium. It can cause hypokalemia, which is a low blood potassium level, not hyperkalemia.
Choice B reason: A serum sodium level of 142 mEq/L is not a common side effect of furosemide, but of normal sodium level. The normal range of serum sodium level is 135 to 145 mEq/L. Sodium is an electrolyte that helps regulate the fluid balance, nerve impulses, and muscle contractions in the body. Furosemide can cause hyponatremia, which is a low blood sodium level, but not a normal sodium level.
Choice C reason: A serum sodium level of 138 mEq/L is also not a common side effect of furosemide, but of normal sodium level. As explained in choice B, the normal range of serum sodium level is 135 to 145 mEq/L. Furosemide can cause hyponatremia, which is a low blood sodium level, but not a normal sodium level.
Choice D reason: A serum potassium level of 2.8 mEq/L is a common side effect of furosemide, and of hypokalemia. Hypokalemia is a condition where the blood potassium level is too low. It can cause muscle cramps, fatigue, weakness, arrhythmias, and paralysis. Furosemide is a loop diuretic that increases the urinary excretion of water, sodium, chloride, and potassium. It can cause hypokalemia, which is a low blood potassium level. The nurse should monitor the client's serum potassium level and signs of hypokalemia, and advise the client to eat potassium-rich foods, such as bananas, oranges, and potatoes. The nurse should also report the lab value to the prescriber, who may adjust the dose of furosemide or prescribe a potassium supplement.

Correct Answer is C
Explanation
Choice A reason: This statement is false. A 12-month-old who is 2-days post-op cleft palate repair whose vital signs are within normal limits is not the priority for pain medication. This infant may have some pain from the surgery, but it is likely to be mild and manageable with non-pharmacological interventions, such as distraction, comfort, or oral care.
Choice B reason: This statement is false. A 6-month-old who is crying and becomes calm when held by a parent is not the priority for pain medication. This infant may have some pain from an unknown cause, but it is likely to be transient and responsive to non-pharmacological interventions, such as soothing, rocking, or cuddling.
Choice C reason: This statement is true. An 8-month-old with legs drawn to chest and a temperature of 39.5 degrees C is the priority for pain medication. This infant may have severe pain from an infection, such as appendicitis, meningitis, or urinary tract infection. This infant may also have signs of inflammation, such as fever, leukocytosis, or elevated C-reactive protein. This infant needs immediate pain relief and antibiotic therapy.
Choice D reason: This statement is false. A 4-month-old that has just returned from the recovery room is not the priority for pain medication. This infant may have some pain from the surgery, but it is likely to be moderate and controlled with pharmacological interventions, such as opioids, NSAIDs, or local anesthetics.
Correct Answer is A
Explanation
Choice A reason: Cushing's syndrome is caused by excess cortisol, a type of glucocorticoid hormone, in the body. This can result from overproduction of cortisol by the adrenal glands, or from prolonged use of corticosteroid medications. Elevated glucocorticoid level is the correct alteration in endocrine function for this condition.
Choice B reason: Decreased aldosterone level is not related to Cushing's syndrome. Aldosterone is another hormone produced by the adrenal glands, but it regulates the balance of sodium and potassium in the body. Decreased aldosterone level can cause low blood pressure, dehydration, and electrolyte imbalance.
Choice C reason: Elevated aldosterone secretion is also not related to Cushing's syndrome. Elevated aldosterone secretion can cause high blood pressure, fluid retention, and hypokalemia (low potassium level). This condition is known as hyperaldosteronism or Conn's syndrome.
Choice D reason: Diminished glucocorticoid level is the opposite of Cushing's syndrome. Diminished glucocorticoid level can cause low blood sugar, fatigue, weight loss, and poor stress response. This condition is known as Addison's disease or adrenal insufficiency.
