Correct Answer: C

Rationale: The correct angle for administering a subcutaneous injection, such as insulin, is 90 degrees. This angle allows for the medication to be delivered into the subcutaneous layer of tissue beneath the skin. A 45-degree angle is typically used for administering subcutaneous injections in infants or those with reduced adipose tissue, while a 60-degree angle is commonly used for intramuscular injections. A 30-degree angle is not a standard angle for subcutaneous injections.

Correct Answer: B

Rationale: The correct answer is B: Meals on Wheels. Meals on Wheels is a community resource that provides food for older adults who are unable to cook for themselves, promoting independence and ensuring proper nutrition. Hospice care (choice A) focuses on providing comfort and support for individuals with life-limiting illnesses; it is not primarily aimed at providing meals. Home health services (choice C) typically involve skilled nursing care and therapy services provided in the home setting, rather than meal delivery. The American Association of Retired Persons (choice D) offers advocacy, support, and resources for older adults but does not directly address the specific needs mentioned in the client's situation.

Correct Answer: D

Rationale: The correct answer is D. Rinsing the skin with soap and water following exposure to the botulism toxin is crucial as it helps remove the toxin from the skin, preventing further absorption. Choices A, B, and C are incorrect. Immunoglobulin E (IgE) is not used in the management of botulism. Airborne precautions are not necessary for botulism as it is not transmitted through the air. Aminoglycoside medications are not the treatment of choice for botulism.

Correct Answer: A

Rationale: The correct action for the nurse to include in the plan of care for an older adult at risk for falls is to lock beds and wheelchairs when not in use. This measure is crucial for preventing falls and ensuring patient safety in healthcare settings. Administering sedatives at bedtime (Choice B) is not recommended as it does not address the underlying risk factors for falls and may increase the risk of injury. Providing information about home safety checks (Choice C) is important for fall prevention in the home environment but is not directly related to healthcare settings. Teaching balance and strengthening exercises (Choice D) is beneficial for fall prevention but may not be suitable for all older adults at risk for falls, especially in acute care settings.

Correct Answer: C

Rationale: The correct answer is C: 'Determine whether the condition is reportable under state requirements.' Listeriosis is a reportable disease, meaning healthcare providers are legally required to report cases to public health authorities. By checking the state requirements for reportable diseases, the nurse ensures compliance with public health regulations. Choice A is incorrect because providing the client's information to the CDC is not the immediate action needed. Choice B is incorrect as direct observation of treatment is not a standard procedure for listeriosis. Choice D is also incorrect as determining if the condition is endemic in the client's neighborhood is not the primary concern when managing a diagnosed case of listeriosis.
