Correct Answer: A

Rationale: The correct answer is A: Diaphoresis. Diaphoresis (sweating) is a classic symptom of hypoglycemia, along with shakiness, confusion, and irritability. These signs help indicate low blood sugar levels. Choices B, C, and D are incorrect. Polyuria (excessive urination), abdominal pain, and thirst are not typical symptoms associated with hypoglycemia. It is crucial for clients with type 1 diabetes mellitus to recognize the early signs of hypoglycemia to take prompt corrective action.

Correct Answer: A

Rationale: Performing chest compressions during cardiac resuscitation is a critical life-saving intervention that can be delegated to an assistive personnel during an emergency. This task requires immediate action and basic training, making it appropriate for delegation. Performing a dressing change for a new amputee involves specialized knowledge and skills, typically performed by licensed healthcare providers. Assessing the effectiveness of medication requires critical thinking and decision-making skills that are within the scope of a licensed healthcare provider. Providing discharge instructions involves educating the patient on post-discharge care and follow-up, which is typically done by a healthcare provider to ensure clear communication and understanding.

Correct Answer: C

Rationale: A temperature of 38.2°C (100.8°F) suggests the possibility of an underlying infection or fever, which should be evaluated before proceeding with the transfusion to prevent complications. Elevated temperature can indicate an immune response to incompatible blood components, increasing the risk of a transfusion reaction. The other vital signs and lab results provided are within acceptable ranges for administering packed RBCs, making choices A, B, and D less likely to cause a delay in the transfusion.

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.

Correct Answer: A

Rationale: Clients should be instructed to complete the entire course of antibiotics, even if they start feeling better, to prevent antibiotic resistance and recurrence of infection.
