Question 1 of 5
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 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.
Question 2 of 5
Which of the ff nursing interventions may reduce hemostasis and decrease the potential for thrombophlebitis for a client with a neurologic disorder?
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.
Question 3 of 5
The client is taking phenyton (Dilantin) for seizure control. A sample is drawn to determine the serum drug level, and the nurse reviews the results. Which of the following would indicate a therapeutic serum drug range?
Correct Answer: A
Rationale: The correct answer is A (5 to 10 mcg/ml) because this range is typically considered therapeutic for phenytoin (Dilantin) for seizure control. Levels below 5 mcg/ml may be subtherapeutic, leading to inadequate seizure control. Levels above 10 mcg/ml can increase the risk of toxicity. Choices B, C, and D are incorrect because they are outside the optimal therapeutic range, leading to either ineffective treatment (B, C) or an increased risk of adverse effects (D). Monitoring drug levels helps ensure the medication's effectiveness while minimizing side effects.
Question 4 of 5
Which of the following would the nurse use to document a finding that the patient’s ear is draining?
Correct Answer: A
Rationale: The correct answer is A: Otorrhea. Otorrhea refers to the discharge of fluid from the ear, indicating an abnormal finding of ear drainage. This term specifically describes the symptom of ear drainage, making it the most appropriate choice for documenting this finding. Otalgia (choice B) refers to ear pain, ototoxic (choice C) refers to substances that are harmful to the ear, and tinnitus (choice D) refers to ringing in the ears, none of which accurately describe ear drainage. Therefore, the correct choice is A as it specifically addresses the symptom of ear drainage.
Question 5 of 5
Which of the ff. descriptions by the nurse would best explain glaucoma to a patient?
Correct Answer: B
Rationale: The correct answer is B: "There is an increase in the intraocular pressure." Glaucoma is a group of eye conditions that damage the optic nerve due to increased pressure within the eye. High intraocular pressure is a key factor in the development of glaucoma. Choice A is incorrect because glaucoma is not associated with an increase in vitreous humor. Choice C is incorrect as glaucoma is not related to a decrease in aqueous humor. Choice D is incorrect because glaucoma is characterized by an increase, not a decrease, in intraocular pressure. Therefore, the most accurate description to explain glaucoma to a patient is the one that mentions the increase in intraocular pressure.
