You are working with a client who has cancer and is undergoing treatment. The client complains of a loss of appetite. You will most need to make certain that your client eats which one of the following foods?

Correct Answer: D

Rationale: For a cancer client with poor appetite, protein is most critical to maintain muscle mass and support healing during treatment. Fruits and vegetables offer vitamins, and carbohydrates provide energy, but protein deficiency risks wasting, common in cancer. Nurses prioritize this nutrient to bolster resilience against treatment side effects.

Correct Answer: C

Rationale: Pain is defined by the client's self-report, per McCaffery's standard, not nurse expertise, cause, or research. Nurses honor this subjective experience for care.

Correct Answer: B

Rationale: Immobility often causes hypoxia due to shallow breathing and limited lung expansion, reducing oxygen delivery to tissues a frequent issue in sedentary patients. This stems from decreased chest movement, risking conditions like atelectasis. Excessive breathing isn't typical, as immobility slows respiratory effort, not accelerates it. Low or high blood pressure relates more to cardiovascular dynamics than lung function in this context. Nurses address this by encouraging deep breathing or repositioning, countering the oxygen deficit that immobility fosters, ensuring respiratory health remains a priority in care planning.

Correct Answer: D

Rationale: For a client with severe hypoxemia, a non-rebreather mask (D) is the most appropriate delivery method because it delivers the highest oxygen concentration up to 95% via a reservoir bag and one-way valves that prevent rebreathing exhaled air, ensuring maximal oxygen intake. Nasal cannula (A) provides low flow (24-44% oxygen) and suits mild hypoxemia, not severe cases. Simple face mask (B) offers moderate oxygen (40-60%) for stable needs, inadequate for severe hypoxemia. Venturi mask (C) delivers precise oxygen (24-50%) for conditions like COPD but not the high levels needed here. The non-rebreather's design addresses acute oxygen deficits effectively, critical in emergencies like severe hypoxemia, aligning with respiratory care standards to prevent tissue hypoxia and organ damage, per AACN guidelines.

Correct Answer: B

Rationale: Adjusting the oxygen flow rate as prescribed (B) is essential for a Venturi mask, ensuring the exact FiO2 (24-50%) matches the order for precise delivery. Continuous SpO2 (A) may be excessive. Lung sounds q-shift (C) are routine. Loose fit (D) reduces accuracy. Prescription adherence, per respiratory standards, optimizes therapy.
