Correct Answer: C

Rationale: The correct answer is C: Efferent neurons transmit impulses from the central nervous system to muscles and glands. This is because efferent neurons are responsible for carrying motor signals away from the central nervous system to control muscle movement and gland secretion. Afferent neurons (choice A) transmit sensory information from the body to the central nervous system. Affective (choice B) is not a term used in neuroscience for describing neuron functions. Effective (choice D) is not a term used in neuroscience and does not describe the specific function of transmitting impulses from the central nervous system to muscles and glands.

Correct Answer: C

Rationale: The correct answer is C: Pneumonia. Early postoperative ambulation helps prevent pneumonia by promoting lung expansion, increasing oxygenation, and preventing atelectasis. A: Increased peristalsis is unrelated to ambulation. B: Coughing is important for airway clearance but not directly related to ambulation. D: Wound healing is influenced by various factors, but ambulation primarily impacts respiratory function.

Correct Answer: C

Rationale: The correct answer is C: Laryngeal cancer. Persistent hoarseness is a common symptom of laryngeal cancer due to vocal cord involvement. Laryngeal cancer causes changes in voice quality over time. Bacterial infection (A) usually presents with acute symptoms and resolves with treatment. Aphonia (B) is the complete loss of voice, not persistent hoarseness. Peritonsillar abscess (D) causes sore throat and difficulty swallowing, but not persistent hoarseness.

Correct Answer: A

Rationale: The correct answer is A: Where is the pain located? This matches with the "Location" component of the PQRST. This question helps determine the specific area where the pain is occurring, providing crucial information for diagnosis and treatment. This step is important in identifying potential underlying issues related to the pain. Summary of other choices: B: What causes the pain? - This question relates to the "Provocation/Palliation" component, not the location. C: Does it come and go? - This question corresponds to the "Quality" component, focusing on the characteristics of the pain. D: What does the pain feel like? - This question aligns with the "Severity" component, concentrating on the intensity of the pain.

Correct Answer: C

Rationale: The correct answer is C because Nursing Outcomes Classification adds objectivity to judging a patient's progress by providing standardized criteria for assessing outcomes. This helps in evaluating the effectiveness of interventions and tracking improvements accurately. Other choices are incorrect: A is wrong because Nursing Outcomes Classification includes 7 domains but not necessarily for level 1; B is incorrect as it uses a 5-point Likert scale, not a 3-point scale; and D is inaccurate because Nursing Outcomes Classification guides the selection of interventions based on the identified outcomes, not allowing complete freedom in choosing interventions.
