Correct Answer: A

Rationale: Step 1: Gerontological nursing certification focuses on advanced knowledge and skills for caring for older adults. Step 2: This certification is not a requirement for all nurses in long-term care or limited to rehabilitation centers. Step 3: Nurses with various levels of education, not just a master's degree, can obtain gerontological certification. Therefore, option A is correct as it accurately states that gerontological nursing certification signifies advanced knowledge and skills specific to older adult care. Options B, C, and D are incorrect as they provide inaccurate information about the certification requirements and scope.

Correct Answer: A

Rationale: The correct answer is A: Diarrhea. Diarrhea is not a risk factor for developing pneumonia in elderly individuals. The rationale for this is that pneumonia is primarily caused by respiratory infections, not gastrointestinal issues like diarrhea. Neurological disease, heart failure, and COPD are all risk factors for pneumonia because they can weaken the immune system or impair lung function, making individuals more susceptible to respiratory infections. These conditions can lead to aspiration, impaired cough reflex, or compromised lung function, increasing the likelihood of developing pneumonia.

Correct Answer: D

Rationale: The correct answer is D because assisting with upper endoscopy is not a standard nursing intervention for CHF. Nursing interventions for CHF focus on managing symptoms, medication adherence, and lifestyle modifications. Choices A, B, and C are correct as they address important aspects of CHF management such as monitoring symptoms, educating on medications, and promoting a low-sodium diet. Helping with an upper endoscopy is unrelated to the management of CHF and falls outside the scope of nursing care for this condition.

Correct Answer: C

Rationale: The correct answer is C because a room with hardwood floor and large windows overlooking a garden area offers a safe, non-slip surface for exercise and natural light for a pleasant environment. Hardwood floors are ideal for exercise to prevent slipping, and the large windows provide a view of the garden area, which can enhance motivation and mood. The other choices are incorrect because A has throw rugs, which can cause tripping hazards, B lacks natural light and ventilation, and D has a linoleum floor which may not be as safe for exercise compared to hardwood.

Correct Answer: D

Rationale: The correct answer is D: Circulatory problems related to age and a chronic illness. Severe edema, hair loss on the legs, and foot ulcerations are indicative of poor circulation, often seen in conditions like peripheral artery disease. Age and chronic illnesses can contribute to circulatory issues. A diet low in protein (choice A) would not directly cause these symptoms. Exposure to cold (choice B) would not explain the specific symptoms mentioned. Frequent falls (choice C) do not align with the symptoms provided.
