Correct Answer: B

Rationale: Muscle weakness is a common finding in clients with hypokalemia, as potassium is essential for proper muscle function. Diarrhea (choice A) is more commonly associated with hyperkalemia rather than hypokalemia. Hypertension (choice C) is not typically a direct result of low potassium levels. Bradycardia (choice D) is more commonly associated with hyperkalemia, not hypokalemia.

Correct Answer: C

Rationale: Correct! Dry mucous membranes are a common finding in clients with dehydration. Dehydration leads to reduced fluid volume in the body, resulting in dryness of mucous membranes, decreased skin turgor, and thirst. Bradycardia (slow heart rate) is not typically associated with dehydration, as the body tries to compensate for decreased fluid volume by increasing heart rate. Hypotension (low blood pressure) is a possible finding in dehydration due to reduced circulating volume. Tachypnea (rapid breathing) is more commonly seen in conditions like respiratory distress or metabolic acidosis, rather than dehydration.

Correct Answer: A

Rationale: The correct answer is A: Hypokalemia. Patients on diuretics are at risk of developing hypokalemia due to increased potassium excretion by the kidneys. Hypokalemia can lead to serious consequences such as cardiac arrhythmias. Hyponatremia (choice B) is an imbalance of sodium levels and is not typically associated with diuretic use. Hyperkalemia (choice C) is the opposite condition where potassium levels are elevated and is less common in patients on diuretics. Hypercalcemia (choice D) is an excess of calcium in the blood and is not directly related to diuretic use. Therefore, monitoring for hypokalemia is crucial in patients taking diuretics.

Correct Answer: A

Rationale: The correct answer is A: Hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss in the body, resulting in hypokalemia. Monitoring potassium levels is crucial in patients on furosemide to prevent complications such as cardiac arrhythmias and muscle weakness. Choice B, hyponatremia, is not typically associated with furosemide use. Hyperkalemia (choice C) and hypercalcemia (choice D) are not commonly linked to furosemide therapy; therefore, they are incorrect choices.

Correct Answer: B

Rationale: The correct instruction is to rinse the mouth after each use of a corticosteroid inhaler to prevent oral candidiasis (thrush). Choice A is incorrect because corticosteroid inhalers are usually used on a regular schedule to control asthma symptoms, not just for acute symptoms. Choice C is incorrect as corticosteroid inhalers are typically used for long-term management, not just during asthma attacks. Choice D is incorrect as administering a bronchodilator after using a corticosteroid is not a standard practice and is not necessary for the effectiveness of the corticosteroid inhaler.
