Correct Answer: C

Rationale: Glucose is the correct value to monitor closely while a client is on total parenteral nutrition. Total parenteral nutrition solutions have high glucose concentrations, necessitating monitoring to prevent complications like hyperglycemia. Calcium, magnesium, and cholesterol are not typically closely monitored during total parenteral nutrition as they are not directly related to the solution's composition or potential associated complications.

Correct Answer: C

Rationale: An 18-month-old child should have approximately 12 teeth. Children typically start getting teeth around 6 months of age. By subtracting 6 from the number of months in the child's age, you can calculate the expected number of teeth. For an 18-month-old child, 18 - 6 = 12 teeth. Therefore, the correct answer is 12 teeth. Choices A, B, and D are incorrect because they do not align with the expected dental development in an 18-month-old child.

Correct Answer: A

Rationale: Major competencies for nurses providing end-of-life care involve a combination of skills and qualities. Demonstrating respect and compassion towards the family and the client is essential in end-of-life care. Additionally, applying knowledge and skills in caring for both the family and the client is crucial to ensure comprehensive and compassionate care. Option A is the correct choice as it accurately reflects these key competencies. Option B, which focuses on assessing and intervening for total management, is important but does not fully address the holistic approach necessary for end-of-life care. Option C, about setting goals and expectations, is relevant but not as critical as the core competencies mentioned in option A. Option D is incorrect as withholding sad news goes against the principles of honesty and transparency in end-of-life care.

Correct Answer: B

Rationale: The therapeutic range for carbamazepine (Tegretol) is 4-10 mcg/mL. This range is established based on the optimal balance between effectiveness and safety. Choices A, C, and D are outside the therapeutic range for carbamazepine, which could lead to suboptimal treatment outcomes or increased risk of toxicity. Choice B (4-10 mcg/mL) is the correct range recommended for therapeutic efficacy while minimizing adverse effects.

Correct Answer: D

Rationale: Scurvy is indeed associated with inadequate intake of vitamin C. Vitamin C deficiency leads to scurvy, which is characterized by weakness, anemia, gum disease, and skin hemorrhages. Choices A, B, and C are incorrect because rickets is caused by vitamin D deficiency, marasmus is due to severe malnutrition leading to wasting, and kwashiorkor is a form of severe protein-energy malnutrition.
