HESI CAT Exam
1. A client admitted to the intensive care unit with syndrome of inappropriate antidiuretic hormone (SIADH) has developed osmotic demyelination. Which intervention should the nurse implement first?
- A. Patch one eye.
- B. Reorient often.
- C. Range of motion.
- D. Evaluate swallow
Correct answer: B
Rationale: Frequent reorientation is crucial for clients with neurological impairments from osmotic demyelination to prevent confusion and assist with orientation. It helps maintain a proper sense of time, place, and person, reducing disorientation. Patching one eye (Choice A) is not a priority intervention for osmotic demyelination and does not address the immediate need for reorientation. Range of motion exercises (Choice C) may be important for overall care, but reorientation takes precedence due to its impact on neurological functioning. Evaluating swallow (Choice D) is not the primary intervention needed for osmotic demyelination; it is essential but not the first priority.
2. After administering a proton pump inhibitor (PPI), which action should the nurse take to evaluate the effectiveness of the medication?
- A. Ask the client about gastrointestinal pain
- B. Measure the client’s fluid intake and output
- C. Monitor the client’s serum electrolyte levels
- D. Auscultate for bowel sounds in all quadrants
Correct answer: A
Rationale: The correct answer is A: Ask the client about gastrointestinal pain. The effectiveness of a proton pump inhibitor (PPI) is best evaluated by assessing the relief of gastrointestinal symptoms, such as heartburn, acid reflux, or stomach pain. These medications work by reducing the production of stomach acid, so improvement in these symptoms indicates the effectiveness of the PPI. Choices B, C, and D are incorrect because they do not directly reflect the effectiveness of a PPI. Measuring fluid intake and output, monitoring serum electrolyte levels, and auscultating for bowel sounds are important for assessing hydration status, electrolyte balance, and gastrointestinal motility, respectively. However, they are not specific to evaluating PPI effectiveness.
3. A client presents to the healthcare provider with fatigue, poor appetite, general malaise, and vague joint pain that improves mid-morning. The client has been using over-the-counter ibuprofen for several months. The healthcare provider makes an initial diagnosis of rheumatoid arthritis (RA). Which laboratory test should the nurse report to the healthcare provider?
- A. Sedimentation rate
- B. White blood cell count
- C. Anti–CCP antibodies
- D. Activated Clotting Time
Correct answer: A
Rationale: The correct answer is A: Sedimentation rate. Sedimentation rate, Anti–CCP antibodies, and C-reactive protein are commonly used laboratory tests to indicate inflammation and help diagnose rheumatoid arthritis. An elevated sedimentation rate is a nonspecific indicator of inflammation in the body, which is often seen in RA. White blood cell count is not specific for RA and is not typically significant in the diagnosis. Anti–CCP antibodies are specific to RA and are useful in confirming the diagnosis. Activated Clotting Time is not relevant to the diagnosis of rheumatoid arthritis as it is not specific to this condition.
4. A 2-year-old boy with short bowel syndrome has progressed to receiving enteral feedings only. Today his stools are occurring more frequently and have a more liquid consistency. His temperature is 102.2 °F, and he has vomited twice in the past four hours. Which assessment finding indicates that the child is becoming dehydrated?
- A. Occult blood in the stool
- B. Abdominal distention
- C. Elevated urine specific gravity
- D. Hyperactive bowel sounds
Correct answer: C
Rationale: Elevated urine specific gravity indicates concentrated urine, a sign of dehydration. In this scenario, the child is showing signs of dehydration with increased stool frequency, liquid consistency, fever, and vomiting. Occult blood in the stool may indicate gastrointestinal bleeding but is not a specific sign of dehydration. Abdominal distention can be seen in various conditions and is not a specific indicator of dehydration. Hyperactive bowel sounds can be present in various gastrointestinal conditions but are not directly related to dehydration.
5. A 13-year-old girl, diagnosed with diabetes mellitus Type 1 at the age of 9, is admitted to the hospital in diabetic ketoacidosis. Which occurrence is the most likely cause of the ketoacidosis?
- A. Ate an extra peanut butter sandwich before gym class
- B. Incorrectly drew up and administered too much insulin
- C. Was not hungry, so she skipped eating lunch
- D. Has had a cold and ear infection for the past two days
Correct answer: B
Rationale: The correct answer is B. Incorrect insulin administration is a common cause of diabetic ketoacidosis. Administering too much insulin can lead to uncontrolled hyperglycemia, where the body starts breaking down fat for energy, resulting in the production of ketones. Choices A, C, and D are less likely to directly cause diabetic ketoacidosis. Eating an extra peanut butter sandwich, skipping lunch, or having a cold and ear infection would not directly lead to the metabolic derangements seen in diabetic ketoacidosis.
