Correct Answer: C

Rationale: Correct Answer: C - Used crutches with no difficulties Rationale: 1. "Used crutches with no difficulties" reflects the patient's successful application of the taught skill. 2. This information indicates the patient's ability to independently perform the task. 3. It demonstrates the effectiveness of the teaching provided by the nurse. 4. "Used crutches with no difficulties" is a specific and objective observation of the patient's performance. Summary: A. "Patient went up and down stairs" is too general and does not indicate the patient's proficiency. B. "Demonstrated use of crutches" does not confirm the patient's actual performance. D. "Deficient knowledge related to never using crutches" is incorrect as it does not reflect the patient's successful use of crutches.

Correct Answer: A

Rationale: The correct answer is A: Hematologic spread. In this case, the cancer cells have traveled through the bloodstream to reach the bones and liver. This process is known as hematologic spread, where cancer cells enter the blood vessels and spread to distant organs. Lymphatic circulation (B) involves the spread of cancer cells through the lymphatic system, which is less likely in this scenario. Invasion (C) refers to cancer cells infiltrating nearby tissues, not distant organs. Angiogenesis (D) is the process of new blood vessel formation to support tumor growth, but it does not explain the spread of cancer cells to other organs.

Correct Answer: B

Rationale: The correct answer is B: Administer calcium gluconate. Magnesium sulfate can cause respiratory depression, leading to a low respiratory rate. Calcium gluconate is the antidote for magnesium sulfate toxicity, as it antagonizes the effects of magnesium on the neuromuscular junction. Administering calcium gluconate helps reverse the respiratory depression caused by magnesium sulfate. Increasing IV fluids (Choice A) is not directly related to treating respiratory depression. Vigorously stimulating the patient (Choice C) can exacerbate respiratory depression. Instructing the patient to take deep breaths (Choice D) may not be effective in addressing the underlying cause of respiratory depression due to magnesium sulfate toxicity.

Correct Answer: D

Rationale: The correct answer is D: Surgical intervention. Cataracts are a clouding of the lens in the eye, which can lead to vision impairment. Surgery is the most common and effective treatment for cataracts, involving the removal of the cloudy lens and replacement with an artificial one. Antioxidant supplements (Choice A) may help prevent cataracts but are not a treatment for existing ones. Eyeglasses or magnifying lenses (Choice B) can help with vision correction but do not address the cataracts themselves. Corticosteroid eye drops (Choice C) are used for treating inflammation in the eye, not cataracts. Therefore, surgical intervention is the most appropriate treatment option for age-related cataracts.

Correct Answer: A

Rationale: The correct answer is A: When the patient is resting. This is because the tremor associated with Parkinson's disease is most noticeable when the patient is at rest due to the characteristic "resting tremor" seen in this condition. The tremor tends to lessen or disappear with purposeful movements or activities, making it more difficult to assess during ambulation, meal preparation, or occupational therapy. By observing the patient at rest, the nurse can accurately assess the presence and severity of the tremor, which is a key diagnostic feature of Parkinson's disease. Other answer choices are incorrect because they do not provide the optimal condition for assessing the tremor associated with Parkinson's disease.
