A nurse is teaching a client newly diagnosed with Emphysema about the disease process. Which of the following statements best explains the problems associated with emphysema and could be adapted for use in the nurse's discussion with the client?

Correct Answer: B

Rationale: The correct answer is: 'Larger than normal air spaces and loss of elastic recoil cause air to be trapped in the lung and collapse airways.' Emphysema is a breakdown of the elastin and fiber network of the alveoli where the alveoli enlarge or the walls are destroyed. This alveolar destruction leads to the formation of larger-than-normal air spaces. Emphysema is one of a group of pulmonary diseases of a chronic nature characterized by increased resistance to airflow; the entity is part of chronic obstructive pulmonary disease (COPD). Choice A is incorrect because emphysema is not primarily characterized by hyperactivity of the medium-sized bronchi causing wheezing and tightness in the chest. Choice C is incorrect because vasodilation, congestion, and mucosal edema are not the primary mechanisms involved in emphysema, and they do not directly lead to chronic cough and sputum production. Choice D is incorrect because emphysema is not related to chloride transport issues and thick viscous mucus production.

Correct Answer: B

Rationale: When a person using over-the-counter nasal decongestant drops experiences unrelieved and worsening nasal congestion, it is crucial to discontinue the medication for a few weeks. Prolonged use of decongestant drops can lead to rebound congestion, which is relieved by stopping the medication for a period of time. Nasal congestion occurs due to various factors like infection, inflammation, or allergy, leading to swelling of the nasal cavity. Nasal decongestants work by stimulating alpha-adrenergic receptors, causing vasoconstriction and shrinking of nasal mucous membranes. However, prolonged use can result in vasodilation, worsening nasal congestion. Switching to a stronger dose of the same medication is not recommended as it can exacerbate the issue. Continuing the same medication more frequently or using a combination of medications are also not advised and may lead to side effects. Educating individuals on proper decongestant use and potential risks of prolonged usage is essential, especially for those with specific health conditions.

Correct Answer: B

Rationale: A client with sickle cell disease has a genetic condition that can be passed on to their offspring. The most appropriate statement for the PN to provide is to acknowledge this fact and inform the client that sickle cell disease is genetically based and might be passed on to children. This empowers the client with accurate information. Choice A has been refined to emphasize discussing the inheritance risk, making it a better option than the vague original choice. Choices C and D provide incorrect information. Sickle cell disease is indeed genetically based and can be inherited.

Correct Answer: C

Rationale: A client newly diagnosed with Diabetes Mellitus requires education on managing their condition. Choice C is the correct answer because it emphasizes the importance of a comprehensive approach involving both diet and exercise. This holistic approach is crucial in managing blood sugar levels and overall health for individuals with diabetes. Choice A is incorrect as it provides misleading information by suggesting that the client can eat anything as long as it doesn't contain sugar, which is not accurate for diabetes management. Choice B is not the best option as it focuses solely on weight loss rather than addressing the holistic needs of a diabetic individual. Choice D is incorrect as it suggests eliminating all salt, fat, and sugar, which is an extreme approach and not a realistic or balanced way to manage diabetes.

Correct Answer: C

Rationale: Placenta previa is a disorder where the placenta implants in the lower uterine segment, causing painless bleeding in the third trimester of pregnancy. The bleeding results from tearing of the placental villi from the uterine wall as the lower uterine segment contracts and dilates. It can be slight or profuse and can include bright red, painless bleeding. While anemia (choice A) may be a consequence of chronic bleeding from placenta previa, it is not a direct indicator. Edema (choice B) and fatigue (choice D) are nonspecific symptoms that can occur in pregnancy but are not specific to placenta previa.
