Correct Answer: D

Rationale: In cystic fibrosis patients with pancreatic insufficiency, pancreatic enzyme replacement therapy is vital for aiding digestion. This therapy helps compensate for the decreased production of digestive enzymes by the pancreas, enabling the proper breakdown and absorption of nutrients. Options A, B, and C are not the primary focus of nutrition therapy for cystic fibrosis patients with pancreatic insufficiency.

Correct Answer: A

Rationale: The correct order of basic CPR steps is as follows: first, ensure the scene is safe to approach, then assess the individual's responsiveness. After confirming the need for help, start chest compressions, then provide two rescue breaths. Option B, 'Give two rescue breaths,' is incorrect as chest compressions should be initiated before giving rescue breaths. Option C, 'Look, listen, and feel for breathing,' is also incorrect as immediate chest compressions are crucial in CPR. Option D, 'Begin chest compressions,' is partially correct but misses the crucial initial steps of ensuring scene safety and assessing responsiveness.

Correct Answer: C

Rationale: The correct answer is C because an audible S3 in a client with mitral valve prolapse could indicate heart failure and requires immediate assessment. Choice A is not as urgent as an audible S3 in mitral valve prolapse. Choice B, a client with coronary artery disease wanting to ambulate, does not present an immediate concern compared to a potential heart failure indicated by an audible S3. Choice D, a client with pericarditis in normal sinus rhythm, is stable and does not require immediate attention when compared to a potential heart failure situation signified by an audible S3 in mitral valve prolapse.

Correct Answer: A

Rationale: Administering intravenous antibiotics is the priority intervention in this scenario. Cellulitis is a bacterial skin infection that requires prompt treatment with antibiotics to prevent its spread and potential complications. While warm moist packs and elevation can be beneficial as adjunct measures, they are not the initial priority. Teaching about skin and foot care is important, but it can be addressed after stabilizing the acute condition with antibiotics.

Correct Answer: B

Rationale: Clients who smoke require more vitamin C due to increased oxidative stress and depletion of vitamin C. Smoking leads to the generation of free radicals in the body, causing oxidative stress and consuming higher levels of antioxidants like vitamin C. Choices A, C, and D are incorrect as they do not directly relate to the increased need for vitamin C as seen in smokers.
