The nurse is teaching an elderly client how to use MDIs (multi-dose inhalers). The nurse is concerned that the client is unable to coordinate the release of the medication with the inhalation phase. What is the nurse's best recommendation to improve the delivery of the medication?

Correct Answer: B

Rationale: Adding a spacer device to the MDI canister is the best recommendation in this scenario. The spacer device helps to improve coordination and medication delivery by allowing the client more time to inhale the medication effectively. Nebulized treatments for home care (Choice A) involve a different delivery method and are not directly related to improving coordination with MDIs. Asking a family member to assist (Choice C) may not address the core issue of coordination between releasing the medication and inhalation. Requesting a visiting nurse (Choice D) may not be necessary if the client can improve coordination with the spacer device.

Correct Answer: B

Rationale: A new or changed heart murmur is a common sign of valve involvement in infective endocarditis, indicating a complication such as valve damage or regurgitation. Dyspnea is more commonly associated with respiratory or cardiac conditions not directly related to infective endocarditis. A macular rash is not a typical symptom of infective endocarditis, suggesting other conditions like infectious diseases. Hemorrhage is not a direct complication of infective endocarditis but may occur due to factors such as anticoagulant therapy or underlying bleeding disorders.

Correct Answer: A

Rationale: The correct answer is A: 'Folic acid should be taken before and after conception.' Folic acid supplementation before and during early pregnancy has been shown to significantly reduce the risk of neural tube defects. Choice B is incorrect because while multivitamin supplements are beneficial during pregnancy, the specific focus for preventing neural tube defects is on folic acid. Choice C is a general statement about a well-balanced diet and does not specifically address neural tube defects. Choice D is incorrect as it focuses on dietary iron, which is important for overall health but not specifically proven to prevent neural tube defects.

Correct Answer: D

Rationale: The correct answer is D. Patients with Parkinson's disease should not stop taking their medication if they feel better, as doing so can worsen symptoms. It is crucial for patients to continue their prescribed medication regimen as directed by their healthcare provider. Choices A, B, and C are all appropriate actions that promote the well-being of a client with Parkinson's disease. Choice A emphasizes medication adherence, which is vital for symptom management. Choice B addresses a common issue in Parkinson's patients and shows an understanding of the importance of dietary management. Choice C highlights the significance of physical activity in maintaining mobility, which is essential for overall quality of life in Parkinson's disease.

Correct Answer: A

Rationale: The correct answer is A: Spinach. Spinach is high in oxalate, a compound that can contribute to the formation of calcium oxalate kidney stones. Therefore, advising the client to avoid spinach is crucial in reducing the risk of stone recurrence. Bananas (choice B) are not high in oxalate and do not directly contribute to the formation of calcium oxalate stones, so they do not need to be avoided. Similarly, choices C and D, chicken, and rice, are not typically associated with high oxalate content, making them safe choices and do not need to be avoided specifically to prevent calcium oxalate kidney stones.
