HESI RN CAT Exam Quizlet

Correct Answer: D

Rationale: Tomatoes and lettuce are high in vitamin C, making them suitable choices for a diet prescribed for wound healing. Bananas and pineapple (Choice A) are not particularly high in vitamin C compared to tomatoes and lettuce. Cottage cheese and crackers (Choice B) as well as peanut butter and jelly (Choice C) do not provide significant amounts of vitamin C, which is essential for wound healing.

Correct Answer: A

Rationale: In a client post-op with low urinary output, the first action the nurse should take is to assess the client's vital signs. Vital signs can provide valuable information about the client's overall condition, fluid status, and potential complications. Assessing the vital signs can help the nurse to determine if the low urine output is indicative of a larger issue that needs immediate attention. Irrigating the catheter with normal saline may be necessary but should not be the first action without assessing the client. Notifying the healthcare provider should follow assessment if there are concerns. Replacing the catheter with a larger size is not indicated solely based on low urinary output and should not be the first action taken.

Correct Answer: A

Rationale: The correct first action when administering medications to a client with a nasogastric tube is to check for tube placement. This is crucial to ensure that the medications are delivered to the correct location within the gastrointestinal tract. Checking the tube placement helps prevent complications such as medication entering the lungs if the tube is misplaced. Crushing the medications (choice B) or flushing the tube with water (choice C) should only be done after confirming the correct tube placement. Administering the medications (choice D) without verifying the tube placement can lead to serious consequences.

Correct Answer: C

Rationale: Swelling of the fingers can indicate compromised circulation, which is a serious concern in a client with a new cast. It could suggest the development of compartment syndrome, a condition where increased pressure within the muscles can lead to impaired blood flow. This can result in tissue damage and should be addressed promptly. Itching under the cast, pain at the cast site, and warmth over the casted area are common findings after cast application and may not necessarily indicate an urgent issue requiring immediate reporting to the healthcare provider.

Correct Answer: B

Rationale: In acute renal failure with a high serum potassium level, the priority intervention is to lower potassium levels to prevent complications like cardiac arrhythmias. Administering a retention enema of Kayexalate is the correct action as it helps lower high potassium levels by exchanging sodium for potassium in the intestines. Options A, C, and D are incorrect. Administering normal saline rapidly and NPH insulin or adding more potassium to the IV solution can further increase potassium levels, worsening the condition. Lidocaine is not indicated for treating hyperkalemia.
