Correct Answer: C

Rationale: The correct answer is C: Axon. The axon is the part of the neuron that transmits impulses away from the cell body towards other neurons or target cells. It is coated with a myelin sheath, which helps speed up the transmission of impulses. Dendrites (A) receive signals from other neurons, the neurolemma (B) is the outermost layer of the myelin sheath, and the synapse (D) is the junction between two neurons where neurotransmitters are released. Therefore, the axon is the only part of the neuron specifically responsible for transmitting impulses away from the cell body.

Correct Answer: D

Rationale: The correct answer is D: Understands discharge instructions. This is crucial for patient safety and recovery post-surgery. Understanding discharge instructions ensures patients know how to care for themselves at home, manage medications, recognize warning signs, and follow-up instructions. Choice A is incorrect as patients should not drive after surgery due to potential impairment. Choice B is incorrect as IV narcotics administration timing is not a discharge criterion. Choice C is irrelevant to the patient's readiness for discharge. Understanding discharge instructions is the key factor in ensuring the patient's well-being and recovery after ambulatory surgery.

Correct Answer: B

Rationale: The correct answer is B: Keep extremities at neutral position. This intervention promotes proper blood flow and reduces the risk of thrombophlebitis by preventing compression or restriction of blood vessels. Removing and reapplying elastic stockings (choice A) can disrupt circulation and increase the risk of thrombophlebitis. Changing the client's position (choice C) may not directly address hemostasis or thrombophlebitis. Using a flotation mattress (choice D) is not specifically focused on maintaining proper positioning of the extremities to promote circulation.

Correct Answer: B

Rationale: The correct answer is B: Nausea and vomiting. Chemotherapeutic drugs commonly cause nausea and vomiting due to their effect on the gastrointestinal system. This is because these drugs can irritate the stomach lining and trigger the vomiting center in the brain. Nausea and vomiting are well-documented side effects of chemotherapy and are often managed with antiemetic medications. A: Painful mouth sores are a common side effect of some chemotherapeutic drugs, but they are not the most common adverse effect. C: Frequent diarrhea can occur as a side effect of chemotherapy, but it is less common than nausea and vomiting. D: Constipation is not a common adverse effect of chemotherapeutic drugs; in fact, diarrhea is more commonly seen.

Correct Answer: A

Rationale: Correct Answer: A - Apply immobilization device after examination by physician Rationale: 1. Immobilization helps reduce pain and prevent further injury. 2. Physician examination ensures proper diagnosis and treatment plan. 3. Immobilization device may include chest binders or splints for support. 4. It is crucial to follow medical advice to prevent complications. Summary: B: Discouraging deep breaths can lead to respiratory complications. C: Advising against analgesics can increase pain and hinder recovery. D: Increased fluid intake is important but not directly related to rib fracture care.
