Correct Answer: D

Rationale: The correct answer is D because systemic lupus erythematosus can lead to inflammation in the lungs, causing abnormal lung sounds. Dysphagia (choice A) is not typically associated with lupus. Dryness or itching of genitalia (choice B) is more characteristic of conditions like yeast infections or dermatitis. Decreased visual acuity or blindness (choice C) is not a common manifestation of lupus. Abnormal lung sounds (choice D) are commonly seen in lupus patients due to inflammation and possible lung involvement.

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: 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: 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 correct answer is B because it encourages the patient to share any additional information they may have forgotten or overlooked, ensuring a thorough health history interview. Choice A is incorrect as it implies the interviewer is unprepared or disinterested. Choice C is inappropriate as it may make the patient feel guilty or inadequate. Choice D is incorrect as it does not address the possibility of gathering more relevant information from the patient.
