Which of the following parts of neuron transmits impulses away from the cell body?

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: C

Rationale: The correct answer is C: The patient is apprehensive about discharge. The rationale is that the patient's fear of going home and being alone indicates anxiety about leaving the hospital setting. This subjective data suggests that the patient may not feel ready for discharge despite stable vital signs and nearly healed incision. Choices A and B are incorrect because they assume the patient's readiness for self-care without considering emotional factors. Choice D is incorrect as there is no evidence provided that the surgery was unsuccessful.

Correct Answer: C

Rationale: The correct answer is C because in Addisonian crisis, the client experiences adrenal insufficiency leading to decreased cortisol levels and impaired stress response. Offering extra blankets and raising room temperature helps prevent hypothermia, as clients in crisis are unable to regulate body temperature. Encouraging independence with ADLs (choice A) and ambulation (choice B) are not priorities as the client is in a critical state. Placing the client in a private room (choice D) is not directly related to managing Addisonian crisis.

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.

Correct Answer: A

Rationale: The correct answer is A: Muscle rigidity and spasms. Ketamine can cause muscle rigidity and spasms as a side effect. The anesthesiologist should monitor the client for this adverse reaction. Muscle rigidity and spasms are common with ketamine administration and can affect the client's comfort and safety during the procedure. It is important for the nurse to promptly address any signs of muscle rigidity or spasms to prevent complications. Summary of why other choices are incorrect: B: Hiccups - Ketamine can cause hiccups, but it is not the primary side effect to monitor for in this scenario. C: Extrapyramidal reactions - Ketamine does not typically cause extrapyramidal reactions. D: Respiratory depression - Ketamine is known for its minimal effect on respiratory depression compared to other anesthetics. Monitoring respiratory depression is still important, but not the primary concern with ketamine administration in this case.

Correct Answer: D

Rationale: The correct answer is D, decreased body temperature and cold intolerance, because these are classic signs of hypothyroidism due to decreased thyroid hormone levels. The body's metabolism slows down, leading to a lower core body temperature and reduced ability to tolerate cold. Exophthalmos and conjunctival redness (choice A) are associated with hyperthyroidism. Flushed, warm, moist skin (choice B) is indicative of hyperthyroidism as well, due to increased metabolic rate. A systolic murmur at the left sternal border (choice C) is not a common finding in hypothyroidism.

Correct Answer: D

Rationale: The correct answer is D - Check for a gag reflex before allowing the patient to drink. This is important after a bronchoscopy to prevent aspiration. Step 1: Assessing gag reflex ensures the patient can protect their airway. Step 2: Aspiration risk is high post-bronchoscopy due to sedation and possible throat numbness. Step 3: Allowing fluids without confirming gag reflex can lead to aspiration pneumonia. Other choices are incorrect. A: Ordering a meal immediately is inappropriate after NPO period. B: Encouraging fluids without assessing gag reflex may lead to aspiration. C: Monitoring consciousness is important but not directly related to post-bronchoscopy care.

Correct Answer: B

Rationale: The correct answer is B because tension headaches typically present as a feeling of pressure or steady constriction on both sides of the head. This is due to muscle tension in the head and neck. Choice A is incorrect as sensitivity to light is more characteristic of migraines. Choice C is incorrect as unilateral paralysis is not typically associated with tension headaches. Choice D is incorrect as vague headache especially peri orbital is not a common symptom of tension headaches. Therefore, the best description of discomfort experienced by a client with a tension headache is the pressure or steady constriction on both sides of the head.

Correct Answer: B

Rationale: The correct answer is B because ordinal petition in the family is not a recognized risk factor for developing cancer. Age is a well-known risk factor as cancer incidence increases with age. Race can also influence cancer risk due to genetic and environmental factors. Lifestyle choices such as smoking, diet, and physical activity can significantly impact the likelihood of developing cancer. In contrast, ordinal petition in the family does not have a direct association with cancer risk.
