1. Which oxygen delivery system would provide the highest concentrations of oxygen to the client?

Correct answer: C

Rationale: The correct answer is the non-rebreather mask. This oxygen delivery system has a one-way valve that prevents exhaled air from entering the reservoir bag and one or more valves covering the air holes on the face mask itself to prevent the inhalation of room air but allow exhalation of air. When a tight seal is achieved around the mask, up to 100% of oxygen is available. Choice A, the Venturi mask, delivers precise oxygen concentrations but not as high as the non-rebreather mask. Choice B, the partial rebreather mask, allows the client to rebreathe some exhaled air, resulting in lower oxygen concentrations than the non-rebreather mask. Choice D, the simple face mask, delivers low to moderate oxygen concentrations and is not designed to provide the highest concentrations like the non-rebreather mask.

2. Which intervention will the nurse include in the plan of care for a patient diagnosed with a lung abscess?

Correct answer: D

Rationale: For a patient diagnosed with a lung abscess, the priority intervention is to educate them about the importance of prolonged antibiotic therapy post-hospital discharge. Long-term antibiotic treatment is crucial for eradicating the infecting organisms in a lung abscess. Chest physiotherapy and postural drainage are not recommended for lung abscess as they can potentially spread the infection. While foul-smelling and bloody sputum are common in lung abscess, immediate notification to the healthcare provider is essential. Avoiding the use of over-the-counter expectorants is not necessary, as expectorants can be used to facilitate coughing and clearing of secretions in this condition.

3. When admitting a 64-year-old patient with acute pancreatitis, the healthcare provider should specifically inquire about a history of

Correct answer: D

Rationale: In patients with acute pancreatitis, alcohol consumption is a significant risk factor and one of the most common causes in the United States. It is crucial to assess alcohol intake as it plays a key role in the development of pancreatitis. While cigarette smoking, diabetes mellitus, and high-protein diets can contribute to various health issues, they are not directly associated with the development of acute pancreatitis.

4. A client is being instructed in the use of an incentive spirometer. Which of the following statements from the nurse indicates correct teaching about using this device?

Correct answer: D

Rationale: An incentive spirometer is a device used to improve lung function and reduce the risk of atelectasis. The correct way to use the spirometer is by sitting up and taking slow, deep breaths to achieve the set goal, not by lying back in a reclining position or taking rapid, quick breaths. Setting a goal of using the spirometer multiple times a day is beneficial, but it is not the best indicator of correct teaching. After using the spirometer, the client should practice coughing to help clear any loosened secretions that may have occurred during the breathing exercises.

5. A home care nurse instructs the mother of a 5-year-old child with lactose intolerance about dietary measures for her child. The nurse should tell the mother that it is necessary to provide which dietary supplement in the child's diet?

Correct answer: D

Rationale: In lactose intolerance, the inability to digest lactose, the sugar in dairy products, can lead to calcium deficiency if dairy products are removed from the diet. Calcium is crucial for bone health and other bodily functions, so alternative calcium sources like fortified non-dairy milks or leafy greens must be included to prevent deficiency. While fats and proteins are important nutrients, they are not typically deficient in lactose intolerance. Zinc, although an essential mineral, is not the primary concern in this case.
