Correct Answer: D

Rationale: Step 1: Monitoring Mrs. GC's color, pulse, and respiration is important to assess for any signs of distress during the procedure. Step 2: Labeling all laboratory specimens in numerical order ensures accurate identification and prevents errors in specimen handling. Step 3: Positioning Mrs. GC on her side with knees drawn up to her chest helps maintain proper spinal alignment and reduces the risk of complications. Summary: Option D is correct because all the interventions mentioned are crucial for ensuring patient safety and procedural success. Options A, B, and C are incorrect individually as they each address only one aspect of the procedure, whereas the correct answer encompasses all necessary interventions.

Correct Answer: D

Rationale: The correct answer is D: leukocytosis. Carbamazepine can cause bone marrow suppression, leading to leukocytosis. Monitoring for elevated white blood cell count is essential to detect this potential complication early. A: Adult respiratory distress syndrome is not a common complication of carbamazepine. B: Elevated levels of phenytoin is not a direct complication of carbamazepine use. C: Diplopia is a common side effect of carbamazepine, not a potential complication like leukocytosis.

Correct Answer: A

Rationale: The correct answer is A: New set of tracheostomy tubes and Oxygen tank. Rationale: 1. New set of tracheostomy tubes: Essential for reinserting the cannulas to secure the airway. 2. Oxygen tank: To ensure James has a stable oxygen supply while the tracheostomy tubes are being reinserted. Summary of incorrect choices: B: Theophylline and Epinephrine - These medications are not directly related to managing a dislodged tracheostomy. C: Obturator and Kelly clamp - While these are useful tools for tracheostomy care, they are not the immediate equipment needed in this emergency situation. D: Sterile saline dressing - This is not relevant for a dislodged tracheostomy; the priority is securing the airway.

Correct Answer: B

Rationale: The correct answer is B: Purplish discoloration of hands and feet. Hand-foot syndrome in sickle cell anemia is characterized by pain, swelling, and purplish discoloration of the hands and feet due to vaso-occlusive crisis. Unequal growth of fingers and toes (A), webbing between fingers and toes (C), and deformities of wrists and ankles (D) are not typical findings associated with hand-foot syndrome in sickle cell anemia.

Correct Answer: A

Rationale: The correct answer is A: Norepinephrine. Norepinephrine is the primary neurotransmitter that mediates the sympathetic response. It is released by sympathetic nerve endings and acts on adrenergic receptors in various target organs to initiate the "fight or flight" response. Prostaglandin, acetylcholine, and serotonin do not directly mediate the sympathetic response and are involved in different physiological processes.
