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, muscles, or glands. Its structure allows for the rapid transmission of electrical signals. Rationale: 1. Dendrites receive signals and transmit them towards the cell body, so A is incorrect. 2. Neurolemma is the outermost layer of a Schwann cell, not a part of the neuron responsible for transmitting impulses, so B is incorrect. 3. The synapse is the junction between two neurons where communication occurs, not a part of the neuron transmitting impulses, so D is incorrect.

Correct Answer: B

Rationale: The correct answer is B: Pallor. Pallor, which refers to paleness of the skin, is an early sign of anemia due to decreased red blood cell levels. Anemia causes reduced oxygen delivery to tissues, leading to paleness. Palpitations (A) may occur in anemia but are not an early sign. Glossitis (C) and weight loss (D) are not typically early signs of anemia and are more commonly associated with other health conditions.

Correct Answer: D

Rationale: The correct answer is D because exhaling deeply before using the spirometer is incorrect. The purpose of the incentive spirometer is to encourage deep inhalation to improve lung function. Exhaling deeply before using the spirometer goes against this goal and may hinder the effectiveness of the device. Choices A, B, and C are all correct actions when using the spirometer. Taking two normal breaths helps to prepare the lungs, sitting upright optimizes lung expansion, and inhaling deeply to reach the target helps to improve lung ventilation.

Correct Answer: C

Rationale: Step-by-step rationale: 1. Anemia is a condition where there is a decrease in the concentration of red blood cells. 2. Red blood cells carry oxygen to the body's tissues, so a decrease in their concentration leads to reduced oxygen delivery. 3. This decrease in red blood cell concentration can be measured through a decrease in hematocrit levels. 4. Choices A and B are incorrect because anemia involves a decrease, not an increase, in red blood cells and hemoglobin. 5. Choice D is incorrect as it mentions "decreased blood count cells," which is not a specific term related to anemia. Summary: The correct answer is C because anemia is characterized by a decrease in the concentration of red blood cells, leading to reduced oxygen delivery, while the other choices are incorrect due to inaccuracies in describing anemia.

Correct Answer: B

Rationale: Step 1: The scenario describes Toni minimizing her visual problems, planning advanced degrees, seeking full-time jobs, and wanting more children. Step 2: Choice B is correct because it recognizes Toni's behavior as a coping mechanism to deal with her illness. Step 3: Minimizing visual problems and focusing on future goals can be a way for Toni to maintain a positive outlook and cope with her challenges. Step 4: Choices A, C, and D are incorrect because they do not address Toni's behavior as a coping mechanism. Choice A mentions euphoria, which is not supported by the scenario. Choice C and D do not acknowledge Toni's coping mechanism but instead focus on different aspects like disease process and physical functioning.
