A nurse is reviewing the plan of care for a client who is receiving oxygen therapy. Which of the following interventions should the nurse include to prevent complications?

Correct Answer: B

Rationale: The correct answer is B: Provide humidified oxygen. Providing humidified oxygen helps prevent dryness and irritation of the respiratory tract during oxygen therapy. This intervention is crucial in preventing complications such as mucous membrane dryness and potential damage to the airways. Checking the client's oxygen saturation every 2 hours (choice A) is essential for monitoring the client's response to therapy but does not directly prevent complications. Instructing the client to perform deep breathing exercises (choice C) is beneficial for respiratory function but does not directly address preventing complications related to oxygen therapy. Using an oxygen mask for delivery (choice D) is a common method of administering oxygen but does not specifically focus on preventing complications like dryness and irritation.

Correct Answer: A

Rationale: The correct intervention to manage fatigue in a client receiving chemotherapy is to encourage the client to take short naps during the day. Fatigue is a common side effect of chemotherapy, and allowing the client to rest can help combat this symptom. Instructing the client to remain on bedrest (Choice B) is not recommended as it may lead to deconditioning and worsen fatigue. Providing a high-calorie diet (Choice C) may be beneficial for overall nutrition but does not directly address fatigue. Encouraging the client to increase activity levels (Choice D) may exacerbate fatigue instead of alleviating it.

Correct Answer: C

Rationale: Administering 4 oz of orange juice is the appropriate action for a client experiencing hypoglycemia due to diabetes mellitus. Orange juice contains simple sugars that can quickly raise blood glucose levels. Insulin (Choice A) would further lower blood sugar, worsening the condition. Glucagon (Choice B) is used in severe hypoglycemia when the client cannot take anything by mouth. Administering 1 L of water (Choice D) is not indicated in hypoglycemia treatment; the priority is to raise blood sugar levels. Therefore, the correct choice is to administer orange juice to address the low blood sugar in this situation.

Correct Answer: B

Rationale: The correct answer is B: Potassium. Furosemide is a loop diuretic that can cause potassium depletion through increased urinary excretion. Monitoring potassium levels is crucial to prevent hypokalemia, which can lead to cardiac dysrhythmias, muscle weakness, and other serious complications. Monitoring sodium, calcium, and magnesium levels is not typically associated with furosemide therapy, making choices A, C, and D incorrect.

Correct Answer: A

Rationale: The most important consideration in managing a patient with heart failure is to monitor daily weight. This allows healthcare providers to assess fluid retention, adjust medications based on weight changes, and detect early signs of worsening heart failure. While oxygen therapy may be necessary in acute situations, it is not a routine management strategy for stable heart failure patients. Encouraging a low-sodium diet is important to manage fluid retention, but daily weight monitoring is a more direct measure of fluid status. Monitoring for signs of fluid overload is essential, but monitoring daily weight is a proactive approach to detect fluid accumulation before overt symptoms appear.
