Correct Answer: B

Rationale: Positioning the client with the affected side down following irrigation is crucial as it helps facilitate drainage of the dislodged cerumen and any remaining irrigation solution. This position allows gravity to assist in the removal of the loosened debris. Wearing sterile gloves is a standard precaution in healthcare procedures to prevent infection but is not specific to ear irrigation. Using body-temperature water or a solution at a slightly warmer temperature is recommended to prevent vertigo and discomfort, so using cool fluid is incorrect. Pulling the pinna upward and backward, not downward, straightens the ear canal for adults to facilitate the irrigation process, making choice D incorrect.

Correct Answer: D

Rationale: In the event of accidental poisoning, it is crucial to know the child's age and weight to determine the appropriate treatment. This information helps healthcare providers calculate the correct dosage of antidotes or medications needed based on the child's size and age. The child's age and weight play a significant role in managing accidental poisoning cases. Therefore, this information should be a priority for parents to communicate in such emergencies. Choices A, B, and C are not as critical as the child's age and weight when it comes to immediate treatment decisions for accidental poisoning.

Correct Answer: A

Rationale: The correct answer is A: Hypertension. Pheochromocytoma is characterized by the overproduction of catecholamines, leading to symptoms such as hypertension. Bradycardia (Choice B) is not typical in pheochromocytoma as increased catecholamines usually lead to tachycardia. Hypoglycemia (Choice C) and weight gain (Choice D) are not commonly associated symptoms of pheochromocytoma.

Correct Answer: A

Rationale: The correct answer is A: 'Is unable to swallow foods by mouth.' Tube feeding is prescribed when a client is unable to safely swallow food by mouth but has a functional gastrointestinal tract. Option B, 'Has a gastrointestinal obstruction,' is incorrect as tube feeding is not typically prescribed for this reason. Option C, 'Requires additional caloric intake to support healing,' is incorrect because tube feeding is specifically for clients who are unable to swallow. Option D, 'Is at risk for aspiration,' is also incorrect as tube feeding would not be the primary intervention for aspiration risk; other strategies to reduce aspiration risk would be implemented instead.

Correct Answer: A

Rationale: The appropriate nursing action when an irregularity in the heart rate is observed is to count the apical pulse rate for a full minute and describe the rhythm in the chart. This approach helps in obtaining an accurate assessment of the irregularities present. Measuring the blood pressure (Choice B) is important but not the immediate priority when an irregular heart rate is noted. Performing an ECG (Choice C) may be necessary but is a more advanced intervention that should follow the initial assessment. Rechecking the heart rate after 5 minutes (Choice D) may delay potential interventions for addressing the irregularity, making it less appropriate than the immediate assessment and documentation of the pulse rhythm.
