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.

Correct Answer: B

Rationale: The primary purpose of using measurable client outcomes during the nursing process is to evaluate the effectiveness of nursing interventions. This is crucial in determining whether the care provided has led to the desired outcomes for the client's health. By measuring outcomes, nurses can assess if the interventions are successful, make any necessary adjustments to the care plan, and ensure optimal patient outcomes. Choice A is incorrect because diagnosing client conditions accurately is not the primary purpose of using measurable client outcomes; it is more related to the initial assessment phase. Choice C is incorrect because prioritizing nursing diagnoses effectively is an important aspect of the nursing process, but it is not the primary purpose of using measurable client outcomes. Choice D is incorrect because while documentation in the client's health record is important, it is not the primary purpose of using measurable client outcomes.

Correct Answer: C

Rationale: The correct answer is C because firm skin turgor indicates adequate hydration, a key goal of fluid resuscitation in diarrhea management. Firm skin turgor reflects the body's fluid balance and hydration status. When fluid resuscitation is successful, the patient's skin turgor improves due to replenished fluid levels. Choices A, B, and D are incorrect as they do not directly assess hydration status or the effectiveness of fluid resuscitation. Passing formed stools, decrease in stool frequency, and absence of perianal burning may be positive outcomes in diarrhea management, but they do not specifically indicate successful fluid resuscitation.

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: C

Rationale: The correct initial action for the nurse is to choose option C: Notify the physician. Increasing oxygen without a healthcare provider's order can be harmful, especially in COPD patients prone to retaining carbon dioxide. The nurse should communicate the situation to the physician to assess the client's condition and adjust the oxygen therapy appropriately. Option A is incorrect as it neglects the potential risks of high oxygen levels. Option B is incorrect as immediate decrease without proper assessment can be dangerous. Option D is not the priority when the client's oxygen therapy needs evaluation.

Correct Answer: A

Rationale: The correct answer is A: Anticholinesterase drugs. These drugs increase acetylcholine levels at neuromuscular junctions, helping improve muscle strength in myasthenia gravis. Adrenergic drugs (B) and beta-blocker drugs (D) are not typically used to treat muscle weakness in myasthenia gravis. Anticholinergic drugs (C) can worsen symptoms by blocking acetylcholine receptors, making them an inappropriate choice for this condition.

Correct Answer: D

Rationale: The correct answer is D because it involves collaboration with the client to validate their experience. It shows respect for the client's perspective and promotes open communication. Choice A is incorrect as it lacks client involvement. Choice B is incorrect as it focuses on the nurse's interpretation rather than the client's experience. Choice C is incorrect as it may come off as accusatory or judgmental, lacking empathy.

Correct Answer: C

Rationale: Subjective data are information reported by the patient that cannot be observed or measured by others. In this case, choice C is correct because the patient describing excitement about discharge is personal and based on the patient's feelings or perceptions. This is subjective data because it is based on the patient's own experiences and emotions. Choices A and B are incorrect because patient's temperature and wound appearance are objective data that can be measured or observed by the nurse. Choice D is also incorrect as patient pacing the floor is an observable behavior, making it objective data. Therefore, choice C is the correct answer as it represents subjective data in the context of the assessment.

Correct Answer: A

Rationale: The correct answer is A: Teaches proper handwashing technique. This is the most appropriate intervention because proper handwashing can help prevent the spread of infection, including urinary infections. Teaching the patient about handwashing empowers them to take control of their own hygiene, reducing the risk of infection. Summary of why other choices are incorrect: B: Properly cleans the patient's toilet - While important for maintaining cleanliness, this does not directly address the patient's risk for a urinary infection. C: Transports urine specimen to the lab - This is not a direct care intervention for preventing urinary infections. D: Informs the oncoming nurse during hand-off - Hand-off communication is important for continuity of care but does not directly address the patient's risk for a urinary infection.
