Question 1 of 5

When using a metered-dose inhaler (MDI), which step is most important for ensuring effective medication delivery?

Correct Answer: A

Rationale: The correct step to ensure effective medication delivery when using a metered-dose inhaler (MDI) is to exhale completely before using the inhaler. This action helps create more space in the lungs for the medication to reach deeply into the airways. Inhaling quickly while pressing down on the inhaler (Choice B) may cause the medication to impact the throat rather than reaching the lungs. Shaking the inhaler for 10 seconds before use (Choice C) is important to mix the medication but not the most crucial step for effective delivery. While holding the breath for 5 seconds after inhaling (Choice D) can help the medication stay in the lungs momentarily, exhaling completely before inhalation is more critical for optimal drug deposition.

Question 2 of 5

The nurse is assessing a client with congestive heart failure who is receiving furosemide (Lasix). Which laboratory value should the nurse monitor closely?

Correct Answer: B

Rationale: The correct answer is B: Potassium level. Furosemide is a loop diuretic that can cause potassium loss, leading to hypokalemia. Monitoring the potassium level is crucial to prevent complications such as cardiac arrhythmias. Sodium level (choice A) is not typically affected by furosemide. Calcium level (choice C) and chloride level (choice D) are also not the primary focus of monitoring when a client is on furosemide for heart failure.

Question 3 of 5

A client with a diagnosis of bipolar disorder is taking lithium. What is the most important information the nurse should provide?

Correct Answer: B

Rationale: The correct answer is B. Sodium levels can affect lithium levels in the body, so it is crucial to monitor sodium intake to prevent toxicity or subtherapeutic levels. Lithium is typically taken on an empty stomach to enhance absorption, making choice A more accurate than the original 'Take the medication with food.' Reporting weight gain, as mentioned in choice C, is important for monitoring side effects but is not as critical as ensuring proper lithium levels through sodium intake monitoring. Choice D, avoiding excessive caffeine intake, is not a priority concern directly related to lithium therapy.

Question 4 of 5

A client with a history of chronic obstructive pulmonary disease (COPD) is prescribed oxygen therapy at 2 liters per minute via nasal cannula. What is the most important instruction the nurse should provide?

Correct Answer: C

Rationale: The most important instruction the nurse should provide to a client with COPD prescribed oxygen therapy is not to adjust the oxygen flow rate without consulting a healthcare provider. This is crucial because too much oxygen can suppress the client's respiratory drive, leading to further complications. Choice A is incorrect because increasing the oxygen flow rate without medical advice can be harmful. Choice B is incorrect as oxygen therapy should be used as prescribed, not just when symptoms occur. Choice D is incorrect as the priority is to ensure the correct oxygen flow rate rather than using a humidifier.

Question 5 of 5

A client with a diagnosis of chronic heart failure is receiving digoxin. What is the most important instruction the nurse should provide?

Correct Answer: B

Rationale: The most important instruction the nurse should provide is to monitor pulse rate daily before taking the medication. Digoxin can lead to bradycardia, so it is crucial to assess the pulse rate before administering the medication. This practice helps ensure that the heart rate is not too low for the safe use of digoxin. Choice A is incorrect as there is no specific requirement to take digoxin with a high-fiber meal. Choice C is also incorrect because there is no need to avoid dairy products while on digoxin. Choice D is incorrect since blurred vision is not a common side effect of digoxin; hence, it is not the most critical instruction to provide.
