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: 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: B

Rationale: The correct answer is B: To prevent respiratory obstruction. An ice collar is used to reduce swelling and inflammation, which can help prevent the abscess from compressing the airway and causing respiratory obstruction. This is crucial in cases of peritonsillar abscess to ensure the client's airway remains patent. Choices A, C, and D do not directly address the primary concern of preventing respiratory obstruction in this context.

Correct Answer: A

Rationale: The correct answer is A because ranking all the patient's nursing diagnoses in order of priority allows the nurse to address the most critical needs first. By prioritizing based on the urgency and potential impact on the patient's health, the nurse can ensure that interventions are carried out effectively. B is incorrect because priorities may need to be adjusted based on the patient's changing condition. C is incorrect as priorities should consider not only physiological but also psychological and sociological factors. D is incorrect because time is an influencing factor, but it should not be the sole consideration when prioritizing interventions.

Correct Answer: D

Rationale: The correct answer is D because morphine helps in acute pulmonary edema by decreasing peripheral resistance, pulmonary capillary pressure, and transudation of fluid. Morphine causes vasodilation, reducing peripheral resistance, which helps redistribute blood flow to the periphery. It also reduces pulmonary capillary pressure by decreasing preload and afterload, leading to decreased fluid transudation into the alveoli. Choices A, B, and C individually do not cover all the effects of morphine in acute pulmonary edema, making them incorrect.

Correct Answer: A

Rationale: Rationale: A: Diphenhydramine hydrochloride (Benadryl) is an antihistamine commonly used to treat allergic reactions, including those from bee stings. It can help alleviate symptoms like itching and swelling. Keeping Benadryl on hand is crucial for managing an allergic reaction promptly. Other Choices: B: Guaifenesin (Robitussin) is an expectorant used to treat coughs, not allergic reactions. C: Pseudoephedrine hydrochloride (Sudafed) is a decongestant used for nasal congestion, not allergic reactions. D: Loperamide (Imodium) is an antidiarrheal used to treat diarrhea, not allergic reactions.

Correct Answer: C

Rationale: The correct answer is C because subjective data refers to information provided by the patient, such as their feelings, perceptions, and symptoms. In this case, the patient describing excitement about discharge is subjective as it is based on their personal experience. The other options (A, B, D) are objective data as they can be measured or observed directly without interpretation. The patient's temperature (A) and wound appearance (B) are physical observations, while the patient pacing the floor (D) is a behavior that can be observed. Therefore, only choice C fits the definition of subjective data in a nursing assessment.

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: A

Rationale: Rationale: Right-sided heart failure leads to fluid backup in the body causing dependent pitting edema due to fluid accumulation in the lower extremities. Orthopnea and exertional dyspnea are typically seen in left-sided heart failure. Hemoptysis is associated with conditions like pulmonary embolism or lung cancer, not right-sided heart failure. Therefore, the correct answer is A as it directly correlates with the symptoms of right-sided heart failure.
