HESI LPN
HESI CAT Exam
1. The parents of a 6-year-old recently diagnosed with asthma should be taught that the symptom of acute episodes of asthma is due to which physiological response?
- A. Inflammation of the mucous membrane & bronchospasm
- B. Increased mucus production and bronchoconstriction
- C. Allergic reactions and hyperventilation
- D. Airway narrowing and decreased lung capacity
Correct answer: A
Rationale: The correct answer is A: Inflammation of the mucous membrane & bronchospasm. Acute asthma episodes are primarily caused by inflammation of the airways and bronchospasm, which lead to airway obstruction. Increased mucus production and bronchoconstriction (Choice B) are part of the physiological responses in asthma but do not directly cause acute episodes. Allergic reactions and hyperventilation (Choice C) are related to asthma triggers and responses but are not the direct causes of acute episodes. Airway narrowing and decreased lung capacity (Choice D) are consequences of inflammation and bronchospasm but do not explain the physiological response leading to acute asthma episodes.
2. While caring for a client's postoperative dressing, the nurse observes purulent wound drainage. Previously, the wound was inflamed and tender but without drainage. Which is the most important action for the nurse to take?
- A. Determine if the drainage has an unpleasant odor.
- B. Monitor the client's white blood cell count (WBC).
- C. Request a culture and sensitivity of the wound.
- D. Cleanse the wound with a sterile saline solution.
Correct answer: C
Rationale: Requesting a culture and sensitivity of the wound is the most crucial action in this scenario. This will help identify the specific organism causing the infection and determine its sensitivity to antibiotics, guiding appropriate antibiotic therapy. Option A is less critical as odor alone may not provide enough information about the type of infection. Monitoring the client's white blood cell count (WBC) in option B is important but not as immediate as obtaining a wound culture. Cleansing the wound with a sterile saline solution in option D is necessary but should follow after obtaining the culture results to ensure proper treatment.
3. A client with Addison's disease started taking hydrocortisone in a divided daily dose last week. It is most important for the nurse to monitor which serum laboratory value?
- A. Osmolarity
- B. Glucose
- C. Albumin
- D. Platelets
Correct answer: B
Rationale: The correct answer is B: Glucose. Hydrocortisone can lead to increased blood glucose levels, so monitoring glucose is crucial to assess for hyperglycemia, a common side effect of corticosteroid therapy. Monitoring osmolarity (choice A) is not typically indicated in this scenario. Albumin (choice C) and platelets (choice D) are not directly affected by hydrocortisone therapy and are not the primary focus of monitoring in this case.
4. A client with borderline personality disorder is admitted to the psychiatric unit after a suicide attempt. The client frequently expresses feelings of emptiness and fears of abandonment. What is the most therapeutic nursing approach for this client?
- A. Encourage the client to participate in all group activities.
- B. Set clear and consistent boundaries while providing empathy.
- C. Reassure the client that the staff will not abandon them.
- D. Explore the client's past relationships in depth.
Correct answer: B
Rationale: The most therapeutic nursing approach for a client with borderline personality disorder, who frequently expresses feelings of emptiness and fears of abandonment, is to set clear and consistent boundaries while providing empathy. This approach helps manage the client's fear of abandonment and feelings of emptiness, which are common in borderline personality disorder. Option A may overwhelm the client in a group setting without addressing their specific needs. Option C, while well-intentioned, may not fully address the underlying issues and may create dependency. Option D delves into the client's past relationships, which may be inappropriate and trigger emotional distress in a vulnerable client.
5. Select the tactile sensation that is accurately paired with its description or procedure for testing.
- A. Fine motor coordination: The use of the fingers
- B. Stereognosis: Equal hearing in both ears
- C. Two-point discrimination: The nurse gently pricks the patient's skin
- D. Gross motor function: The use of the lower limbs
Correct answer: C
Rationale: The correct answer is C: Two-point discrimination: The nurse gently pricks the patient's skin. Two-point discrimination assesses the ability to discern two points touched simultaneously on the skin. Fine motor coordination (Choice A) refers to the precise movements of small muscles, not related to tactile sensation. Stereognosis (Choice B) is the ability to recognize objects by touch, not equal hearing in both ears. Gross motor function (Choice D) involves the coordination of large muscle groups, not specifically related to tactile sensation testing.
