Correct Answer: B

Rationale: The correct answer is B because insulin cannot be taken orally as it gets destroyed by stomach acid. Choice A is incorrect as the speed of action is not the reason why insulin can't be in pill form. Choice C is incorrect as it doesn't address the nature of insulin. Choice D is incorrect as it doesn't provide a factual reason why insulin can't be in pill form.

Correct Answer: B

Rationale: High doses of prednisone are commonly prescribed for giant cell arthritis to reduce inflammation. Aspirin is not typically used for this condition. Methotrexate is more commonly used for conditions like rheumatoid arthritis, not giant cell arthritis. Albuterol is a bronchodilator used for respiratory conditions, not for giant cell arthritis.

Correct Answer: C

Rationale: The nurse should contact the case manager to discuss discharge options and support the client's partner. This action is appropriate as it involves seeking professional guidance and support for the client's partner who is struggling to care for the client. Option A is not the best choice as it solely focuses on involving another family member without addressing the partner's concerns directly. Option B is premature as recommending long-term care should be a well-considered decision involving multiple healthcare professionals. Option D delays the inevitable without providing a solution to the partner's current challenges.

Correct Answer: B

Rationale: Rotating injection sites when administering insulin helps prevent insulin lipodystrophy, which is the abnormal distribution of fat at injection sites. Insulin edema (choice A) is not prevented by rotating injection sites; it is characterized by swelling at the site of insulin injection due to increased capillary permeability. Insulin resistance (choice C) is a condition where the body's cells become less responsive to insulin, and rotating injection sites does not directly prevent this. Systemic allergic reactions (choice D) are not specifically prevented by rotating injection sites; they are related to an allergic response to insulin.

Correct Answer: B

Rationale: The correct answer is B: Preventive care. Primary healthcare emphasizes preventive care, which includes promoting overall health, preventing diseases, and providing early intervention to avoid the progression of illnesses. Emergency care (choice A) is focused on immediate medical attention for urgent health situations but is not the primary focus of primary healthcare. Specialized treatment (choice C) refers to care provided by specialists for specific health conditions, which is not the main focus of primary healthcare. Hospital-based services (choice D) involve inpatient care provided in a hospital setting, which is not the primary focus of primary healthcare that aims to provide comprehensive and accessible care at the community level.
