HESI LPN
CAT Exam Practice Test
1. While changing a client’s chest tube dressing, the nurse notes a crackling sensation when gentle pressure is applied to the skin at the insertion site. What is the best action for the nurse to take?
- A. Apply a pressure dressing around the chest tube insertion site
- B. Assess the client for allergies to topical cleaning agents
- C. Measure the area of swelling and crackling
- D. Administer an oral antihistamine per PRN protocol
Correct answer: A
Rationale: A crackling sensation indicates subcutaneous emphysema, caused by air trapped under the skin. Applying a pressure dressing around the chest tube insertion site can help manage the issue by preventing further air leakage into the tissues. Choice B is incorrect because the crackling sensation is not related to allergies. Choice C is incorrect as measuring the area does not address the underlying cause. Choice D is incorrect as administering an oral antihistamine is not indicated for subcutaneous emphysema.
2. A client with chronic renal failure is receiving erythropoietin (Epogen). The nurse should monitor the client for which of the following side effects?
- A. Hypertension
- B. Hypoglycemia
- C. Hyperkalemia
- D. Hypocalcemia
Correct answer: A
Rationale: The correct answer is A: Hypertension. Erythropoietin can lead to hypertension as a side effect due to its stimulation of red blood cell production, which can increase blood viscosity. This can result in elevated blood pressure. Choices B, C, and D are incorrect. Hypoglycemia is not a common side effect of erythropoietin. Hyperkalemia is more commonly associated with renal failure rather than erythropoietin use. Hypocalcemia is not a typical side effect of erythropoietin administration.
3. A nurse on a medical-surgical unit is receiving a change-of-shift report for four clients. Which of the following clients should the nurse see first?
- A. A client who has new onset of dyspnea 24 hours after a total hip arthroplasty
- B. A client who has acute abdominal pain rated 4 on a scale from 0 to 10
- C. A client who has a UTI and low-grade fever
- D. A client who has pneumonia and an oxygen saturation of 96%
Correct answer: A
Rationale: The nurse should see the client who has new onset of dyspnea 24 hours after a total hip arthroplasty first. New onset of dyspnea, especially after surgery, can indicate a serious complication such as a pulmonary embolism or deep vein thrombosis. It is essential to assess this client promptly to rule out potentially life-threatening conditions. Acute abdominal pain, a UTI with low-grade fever, and pneumonia with an oxygen saturation of 96% are important issues but do not indicate the urgency and potential severity of a post-operative complication like pulmonary embolism or deep vein thrombosis.
4. When a nurse assigned to a manipulative client for 5 days becomes aware of feelings of reluctance to interact with the client, what should be the next action by the nurse?
- A. Discuss the feeling of reluctance with an objective peer or supervisor
- B. Limit contact with the client to avoid reinforcement of the manipulative behavior
- C. Confront the client about the negative effects of behaviors on other clients and staff
- D. Develop a behavior modification plan that will promote more functional behavior
Correct answer: A
Rationale: The correct action for the nurse in this situation is to discuss the feeling of reluctance with an objective peer or supervisor. By doing so, the nurse can address their emotions professionally and seek guidance on how to manage the situation effectively. This approach allows the nurse to receive support and potentially gain insights on how to navigate interactions with the manipulative client. Option B is incorrect because avoiding the client may not address the underlying issues causing the reluctance and can impact the quality of care provided. Option C is inappropriate as confronting the client directly about negative behaviors may escalate the situation and harm the therapeutic relationship. Option D is not the immediate action needed in this scenario; it is essential to address the nurse's feelings first before considering behavior modification plans.
5. A child with Duchenne muscular dystrophy is to receive prednisone as part of his treatment plan. After teaching the child's parents about this drug, which statement by the parents indicates the need for additional teaching?
- A. We should give this drug after he eats something.
- B. We need to watch carefully for possible infections.
- C. The drug should not be stopped abruptly.
- D. He might experience weight gain with this drug.
Correct answer: A
Rationale: Giving prednisone with food helps prevent gastrointestinal upset. Therefore, the correct statement is that the drug should be given after the child eats something, not before. Watching for infections is important due to prednisone's immunosuppressive effects, making choice B correct. Choice C is accurate because prednisone should be tapered off gradually to prevent withdrawal symptoms. Weight gain is a common side effect of prednisone, so choice D is also correct. The incorrect statement is choice A, as prednisone should be administered after a meal.
