A client with a history of heart failure is receiving furosemide. Which of the following laboratory values should the nurse monitor?
- A. Sodium 140 mEq/L
- B. Calcium 9.0 mg/dL
- C. Potassium 3.2 mEq/L
- D. Chloride 100 mEq/L
Correct Answer: C
Rationale: The correct answer is C: Potassium 3.2 mEq/L. A potassium level of 3.2 mEq/L is below the normal range and should be monitored in clients receiving furosemide due to the risk of hypokalemia. Furosemide is a loop diuretic that can cause potassium depletion, leading to hypokalemia. Monitoring potassium levels is crucial to prevent complications such as cardiac arrhythmias. Choices A, B, and D are not directly impacted by furosemide therapy in the same way as potassium levels, making them less relevant for monitoring in this scenario.

A nurse is teaching a newly licensed nurse about using a portable oxygen system. What instruction should the nurse include?
- A. The oxygen should be kept in a storage room when not in use.
- B. Turn off the oxygen when not in use.
- C. Check the oxygen level regularly using a pulse oximeter.
- D. Never leave the oxygen running when transporting a client.
Correct Answer: C
Rationale: The correct answer is to check the oxygen level regularly using a pulse oximeter. This instruction is crucial as it ensures safe and adequate oxygenation for the client. Option A is incorrect as oxygen should not be stored in a storage room but in a well-ventilated area. Option B is not ideal as oxygen should be left on unless otherwise specified by a healthcare provider. Option D is also important but not directly related to the primary instruction of monitoring oxygen levels.
A healthcare provider is teaching a client who has a new diagnosis of hypertension about dietary management. Which of the following foods should the healthcare provider recommend?
- A. Carrots
- B. Whole grains
- C. Lean beef
- D. Bananas
Correct Answer: C
Rationale: The correct answer is 'Lean beef.' Lean beef is a good source of protein, which is essential for a balanced diet. While carrots and bananas are healthy food choices, they are not specifically recommended for clients with hypertension. Whole grains are a better alternative to refined grains for individuals with hypertension, but lean beef is a more suitable recommendation due to its protein content.
A client is being taught about patient-controlled analgesia (PCA). Which statement should be included in the teaching?
- A. The PCA will deliver a double dose of medication when you push the button twice.
- B. Continuous PCA infusion is designed to allow fluctuating plasma medication levels.
- C. You should push the button before physical activity to allow maximum pain control.
- D. You can adjust the amount of pain medication you receive by pushing on the keypad.
Correct Answer: D
Rationale: The correct statement to include in the teaching about PCA is that the client can adjust the amount of pain medication they receive by pushing on the keypad. This empowers the client to control their pain management effectively. Choice A is incorrect because PCA systems are programmed to prevent double dosing when the button is pressed multiple times in quick succession. Choice B is incorrect as continuous PCA infusion aims to maintain a steady plasma medication level. Choice C is incorrect because it is not necessary to push the button before physical activity to ensure maximum pain control; the client should use the PCA as needed for pain relief.
A client has a new prescription for hydrochlorothiazide. Which of the following instructions should the nurse include?
- A. Take this medication at bedtime to prevent dizziness.
- B. Increase your intake of potassium-rich foods.
- C. Take this medication with food to prevent gastrointestinal upset.
- D. This medication can increase your blood pressure.
Correct Answer: B
Rationale: The correct instruction that the nurse should include for a client prescribed hydrochlorothiazide is to increase their intake of potassium-rich foods. Hydrochlorothiazide is a diuretic that can lead to potassium depletion, so increasing potassium-rich foods helps prevent hypokalemia. Option A is incorrect because hydrochlorothiazide is usually taken in the morning to prevent diuresis at night. Option C is not necessary as hydrochlorothiazide can be taken with or without food. Option D is incorrect because hydrochlorothiazide is used to lower blood pressure, not increase it.
A client who has a new prescription for spironolactone is being taught by a nurse. Which of the following client statements indicates an understanding of the teaching?
- A. I will avoid foods that are high in potassium.
- B. I will avoid foods that are high in sodium.
- C. I will need to have my blood pressure checked regularly while taking this medication.
- D. I will need to have my potassium levels checked regularly while taking this medication.
Correct Answer: D
Rationale: The correct answer is D because clients taking spironolactone should have their potassium levels checked regularly. Spironolactone is a potassium-sparing diuretic, meaning it helps the body retain potassium and can lead to hyperkalemia if levels become too high. Choices A, B, and C are incorrect because avoiding foods high in potassium, sodium, or monitoring blood pressure are not specific to the teaching related to spironolactone.
