Correct Answer: C

Rationale: The correct answer is C: Bradycardia. Digoxin toxicity often presents with bradycardia, which is a common sign of toxicity associated with this medication. Tachycardia (Choice A) is not typically seen with digoxin toxicity. Hypotension (Choice B) can occur but is less specific to digoxin toxicity. Hyperglycemia (Choice D) is not a typical sign of digoxin toxicity. Therefore, monitoring for bradycardia is crucial in clients receiving digoxin to detect toxicity early.

Correct Answer: D

Rationale: In this situation, the nurse should first stabilize the client's neck to prevent potential spinal cord injuries. Logrolling the client or performing other assessments should only be done after ensuring spinal stabilization. Opening the airway immediately is important in cases of airway obstruction, but stabilizing the neck takes priority in this scenario. Performing a complete neurological assessment may delay immediate stabilization, which is crucial in suspected spinal injuries.

Correct Answer: C

Rationale: The correct answer is 'Normal breathing.' A respiratory rate of 41 breaths per minute is considered normal for an 18-month-old child. Choices A, B, and D are incorrect because a respiratory rate of 41 breaths per minute falls within the normal range for a child of James' age and does not indicate slow, fast, or very fast breathing.

Correct Answer: D

Rationale: Risk for aspiration is a priority concern following a seizure, especially when the child vomits, as there is a danger of aspirating the vomit into the lungs, leading to respiratory complications. The other options are not the priority in this situation. While infection risk and fluid volume deficit are important, ensuring the child's airway is clear and there is no risk of aspiration takes precedence. Altered family processes may be a concern but addressing the immediate physiological risk is the priority.

Correct Answer: B

Rationale: The correct answer is B: Left ventricular end-diastolic pressure. Pulmonary capillary wedge pressure is used to assess left ventricular end-diastolic pressure. This measurement provides valuable information on the filling pressure of the left ventricle. Choices A, C, and D are incorrect because monitoring pulmonary capillary wedge pressure does not directly assess right ventricular pressure, acid-base balance, or coronary artery stability.
