Correct Answer: B

Rationale: The correct answer is B. Sucralfate should be taken on an empty stomach, 1 hour before meals. This timing allows sucralfate to form a protective barrier over the ulcer, enhancing healing. Choice A is incorrect because sucralfate should not be taken with an antacid. Choice C is incorrect because sucralfate should not be taken with food. Choice D is incorrect because sucralfate should not be taken at bedtime only; it is best absorbed on an empty stomach.

Correct Answer: D

Rationale: The correct answer is D because transporting a stable child to x-ray is a task that can be safely delegated to an assistive personnel. This task does not require clinical judgment or specialized skills. Choices A, B, and C involve assessments and interventions that require nursing judgment and should be performed by a qualified nurse. Initiating a dietary consult for a toddler involves assessing the child's nutritional needs and must be done by a nurse. Administering a glycerin suppository to a preschool-age child requires medication administration skills and knowledge of appropriate dosages, which are within the nurse's scope of practice. Evaluating gastric residual following intermittent feeding of an adolescent is a clinical assessment that requires interpretation and decision-making based on the findings, making it a nursing responsibility.

Correct Answer: B

Rationale: The correct answer is B: Glycosylated hemoglobin (HbA1c). The glycosylated hemoglobin test measures average blood glucose levels over the past 2-3 months, providing an indication of long-term glycemic control in clients with diabetes. Choice A, postprandial blood glucose, reflects blood sugar levels after a meal and does not provide a long-term view. Choice C, glucose tolerance test, evaluates the body's ability to process sugar but does not offer a continuous assessment like the HbA1c test. Choice D, fasting blood glucose, measures blood sugar levels after a period of fasting, which is more indicative of immediate glycemic status rather than long-term management.

Correct Answer: D

Rationale: The correct answer is to have naloxone available in case of respiratory depression. Morphine is an opioid that can lead to respiratory depression, especially in higher doses. Naloxone is the antidote for opioid overdose and should be readily accessible when administering morphine to reverse respiratory depression if it occurs. Instructing the client to take a deep breath during administration (choice A) is not directly related to ensuring safety in this scenario. Administering the medication over 30 seconds (choice B) may help with the comfort of the client but does not address the potential risk of respiratory depression. Verifying the client's pain level (choice C) is important but not the primary action to ensure safety when administering morphine.

Correct Answer: B

Rationale: A PaCO2 level of 55 mm Hg indicates hypercapnia, which is common in clients with emphysema but may require further treatment if it leads to respiratory acidosis or distress. Elevated PaCO2 levels can indicate inadequate ventilation and impaired gas exchange, potentially leading to respiratory acidosis. The other results fall within normal ranges or compensated values for a client with chronic emphysema and do not necessarily indicate the need for immediate intervention.
