Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. Aseptic technique prevents infection at IV site. 2. TPN is a high-risk solution, requiring strict aseptic administration. 3. Contaminated site can lead to sepsis or other serious complications. 4. Choice B increases risk of contamination. 5. Choice C increases risk of bacterial growth. 6. Choice D may introduce air or contamination. Summary: Choice A is correct as it emphasizes infection prevention. Choices B, C, and D pose risks of contamination, bacterial growth, or air introduction.

Correct Answer: A

Rationale: The correct answer is A because hyperparathyroidism is not caused by increased levels of thyroxine but by overactivity of the parathyroid glands. This would lead to symptoms of heat intolerance due to increased metabolism and systolic hypertension due to the effects of excess parathyroid hormone on calcium levels. Choice B is incorrect because diastolic hypertension and widened pulse pressure are not typical symptoms of hyperparathyroidism. Choice C is incorrect because weight gain is not a common symptom of hyperparathyroidism. Choice D is incorrect because anorexia and hyper-excitability are not typical symptoms of hyperparathyroidism.

Correct Answer: B

Rationale: The correct answer is B because it encourages the patient to reflect on potential causes of their fatigue, leading to a more in-depth exploration of the issue. Option A focuses on stress, not necessarily fatigue. Option C is too specific and may not uncover underlying causes. Option D assumes sleep duration is the only factor contributing to fatigue.

Correct Answer: D

Rationale: The correct answer is D: Reduce airway inflammation. Corticosteroids like methylprednisolone are used in emphysema to reduce inflammation in the airways, which can help improve lung function and symptoms. Corticosteroids work by suppressing the immune response that leads to inflammation in the airways. This can help decrease swelling, mucus production, and constriction of the airways, all of which contribute to the symptoms of emphysema. Dry secretions (choice A) and improving oxygen-carrying capacity (choice B) are not the primary purposes of corticosteroid treatment in emphysema. Treating infection that causes a low level of hemoglobin (choice C) is not relevant to corticosteroid treatment for emphysema.

Correct Answer: C

Rationale: The correct answer is C: Amount and color of sinus drainage. Assessing the amount and color of sinus drainage is crucial in evaluating the effectiveness of nursing interventions for sinusitis discomfort as it indicates the presence of infection or inflammation. Changes in color or amount can signify improvement or worsening of the condition. WBC count (A) may indicate infection but doesn't directly reflect sinusitis discomfort. Capillary refill (B) assesses circulation, not sinusitis. Comfort level (D) is subjective and can vary among individuals, making it less reliable for assessing the effectiveness of interventions.
