HESI RN CAT Exit Exam

Correct Answer: A

Rationale: Administering an antiemetic before meals is a crucial intervention to manage chemotherapy-induced nausea. Antiemetics help prevent or reduce nausea and vomiting associated with chemotherapy. Providing frequent mouth care (choice B) is important for managing oral mucositis but not specifically for nausea. Encouraging small, frequent meals (choice C) and offering clear liquids (choice D) are beneficial strategies for managing gastrointestinal side effects but may not be as effective in controlling nausea as administering antiemetics.

Correct Answer: A

Rationale: In a 3-year-old boy presenting with dysphagia, drooling, fever, and stridor, the priority intervention should be to place the child in a mist tent. This intervention helps alleviate respiratory distress, providing immediate relief. Options B, C, and D are not as urgent as ensuring the child's airway is managed effectively. Obtaining a sputum culture, preparing for a tracheostomy, and examining the oropharynx can be done after stabilizing the child's respiratory status.

Correct Answer: C

Rationale: The correct action for the nurse to take first when a client with COPD reports difficulty breathing while receiving oxygen is to check the client's oxygen saturation level. This helps in determining the adequacy of oxygenation and identifying the cause of the breathing difficulty. Increasing the oxygen flow rate (Choice A) may not be appropriate without knowing the current oxygen saturation level. Instructing the client to breathe deeply and cough (Choice B) may not address the immediate need for oxygen assessment. Placing the client in a high-Fowler's position (Choice D) can help with breathing but should come after ensuring proper oxygenation.

Correct Answer: A

Rationale: The correct answer is A: 'Blow cool air from a hairdryer under the cast.' Blowing cool air can help relieve itching without damaging the cast or causing injury. Choice B, twisting the cast back and forth, can lead to discomfort, skin irritation, or even injury. Choice C, shaking powder into the cast, can create a mess, increase the risk of skin issues, and interfere with proper healing. Choice D, pushing a pencil under the cast edge, is dangerous as it can cause injury to the child's skin or the underlying tissues. Therefore, the safest and most effective option to relieve itching under the cast is to blow cool air from a hair dryer.

Correct Answer: D

Rationale: In acute glomerulonephritis, maintaining fluid balance is the priority to prevent complications like fluid overload or dehydration. Monitoring urine output within the range of 1 to 2 ml/kg/hr is crucial in assessing renal function. While activity tolerance, skin integrity, and nutritional status are important aspects of care, fluid balance takes precedence due to its direct impact on the renal condition and overall health outcome for the child.
