Correct Answer: D

Rationale: To best listen to breath sounds, the nurse should have the client sit, leaning slightly forward, with arms resting comfortably across the lap. The client should be instructed to breathe through the mouth a little deeper than usual, but to stop if feeling dizzy. The nurse should hold the flat diaphragm end piece of the stethoscope firmly against the client's chest wall. It is crucial to listen for at least one full respiration in each location on the chest to assess breath sounds accurately. Side-to-side comparison is essential in breath sound assessment. Therefore, options A, B, and C are incorrect as they do not align with the correct procedure for listening to breath sounds.

Correct Answer: D

Rationale: The nurse should follow up on the client's lack of a support system. Even if there is no family in the area, there are supportive resources in the community that may help the client through the pregnancy and into motherhood. It is normal for the client to worry about labor, address financial concerns, and express displeasure from early pregnancy symptoms such as nausea. However, the priority is to address the client's statement about preparing to handle the pregnancy on her own due to the absence of nearby family support. This could have significant implications for the client's emotional well-being and ability to cope effectively throughout the pregnancy journey.

Correct Answer: C

Rationale: The correct answer is 'getting out of bed to use the bathroom.' Risperdal can cause orthostatic hypotension, leading to a drop in blood pressure when changing positions from lying down to standing up. This effect increases the risk of falls, emphasizing the need to assist the client with this task to prevent potential harm. Choices A, B, and D are less likely to be directly impacted by the medication, unlike the significant risk of orthostatic hypotension associated with changing positions.

Correct Answer: C

Rationale: The least appropriate action is for the LPN to administer all ordered medications except for the Cefazolin. The LPN should always consider the client's documented allergy to Penicillin seriously. It is crucial to discuss the order with the care team before administering Cefazolin to ensure patient safety. Administering a medication that could potentially cause harm due to a documented allergy is unsafe practice. While monitoring the client after a test dose of Cefazolin is important, it should not precede clarification with the care team regarding the allergy and the appropriateness of the medication. Therefore, withholding the Cefazolin is the most appropriate action in this scenario.

Correct Answer: C

Rationale: Kleinman's Explanatory Model of Health and Illness is significant because it emphasizes the influence of popular and folk domains on health perceptions. Kleinman distinguishes between disease, representing the biomedical view, and illness, reflecting individual understanding. The model underscores that cultural factors shape the significance of popular and folk influences on health beliefs. Choice A is incorrect as the model focuses on broader cultural influences, not individual family beliefs. Choice B is incorrect as it oversimplifies the model's emphasis on various cultural aspects. Choice D is incorrect as the model's significance lies in its cultural framework rather than an educational base.
