Nursing Elites

1. A nurse is preparing to administer potassium chloride IV to a client who has hypokalemia. Which of the following actions should the nurse take?

• A. Give the medication as a bolus over 10 minutes.
• B. Dilute the medication before administration.
• C. Infuse the medication at a rate of 10 mEq/hr.
• D. Administer the medication undiluted.

Correct answer: C

Rationale: The correct action the nurse should take when administering potassium chloride IV to a client with hypokalemia is to infuse the medication at a rate of 10 mEq/hr. This slow infusion rate is crucial to prevent the development of hyperkalemia, a potentially dangerous condition. Option A is incorrect because giving the medication as a bolus over 10 minutes can lead to adverse effects. Option B is incorrect as potassium chloride does not necessarily need to be diluted before administration in this scenario. Option D is incorrect as administering the medication undiluted can also increase the risk of hyperkalemia.

2. A nurse is assessing a client who is receiving furosemide for heart failure. Which of the following findings is the priority to report to the provider?

• A. Blood pressure of 98/58 mm Hg
• B. Urine output of 50 mL/hr
• C. Serum potassium level of 3.2 mEq/L
• D. Weight loss of 0.5 kg (1.1 lb) in 24 hours

Correct answer: C

Rationale: The correct answer is C. A serum potassium level of 3.2 mEq/L indicates hypokalemia, a potential complication of furosemide therapy, and should be reported immediately. Hypokalemia can lead to serious cardiac dysrhythmias. Choices A, B, and D are important assessments but are not as critical as managing serum potassium levels in a client receiving furosemide for heart failure.

3. Which electrolyte imbalance is commonly seen in patients receiving furosemide?

• A. Hypokalemia
• B. Hypercalcemia
• C. Hyponatremia
• D. Hyperkalemia

Correct answer: A

Rationale: The correct answer is A: Hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss, resulting in hypokalemia. This electrolyte imbalance necessitates close monitoring to prevent complications such as cardiac arrhythmias. Choices B, C, and D are incorrect. Hypercalcemia is not a common side effect of furosemide. Hyponatremia is more commonly associated with other medications like thiazide diuretics. Hyperkalemia is the opposite electrolyte imbalance and is not typically seen with furosemide use.

4. A nurse is providing discharge teaching to a client who has a new prescription for lithium. Which of the following instructions should the nurse include?

• A. Take this medication on an empty stomach.
• B. Avoid eating foods that contain tyramine.
• C. Drink at least 2 liters of water each day.
• D. Take this medication in the evening before bedtime.

Correct answer: C

Rationale: The correct instruction for a client prescribed lithium is to drink at least 2 liters of water each day. This is important to prevent dehydration and reduce the risk of lithium toxicity. Option A is incorrect because lithium is usually taken with food to minimize gastrointestinal side effects. Option B is unrelated to lithium and is more applicable to clients taking MAOIs. Option D is incorrect as lithium is typically taken in divided doses throughout the day to maintain therapeutic levels.

5. Which electrolyte imbalance is common in patients receiving diuretics?

• A. Hypokalemia
• B. Hypercalcemia
• C. Hyponatremia
• D. Hypermagnesemia

Correct answer: A

Rationale: The correct answer is Hypokalemia. Diuretics, such as furosemide, commonly cause potassium loss in patients, leading to hypokalemia. This electrolyte imbalance should be closely monitored to prevent complications like cardiac arrhythmias. Hypercalcemia (Choice B) is not typically associated with diuretic use. Hyponatremia (Choice C) involves low sodium levels and can occur in conditions like syndrome of inappropriate antidiuretic hormone secretion (SIADH) but is not directly caused by diuretics. Hypermagnesemia (Choice D) is an excess of magnesium, usually not a common electrolyte imbalance induced by diuretics.
