Fundamentals of Nursing HESI
1. Which of the following manifestations confirms the presence of pediculosis capitis in students?
- A. Scratching the head more than usual
- B. Flakes evident on a student's shoulders
- C. Oval pattern occipital hair loss
- D. Whitish oval specks sticking to the hair
Correct answer: D
Rationale: The correct answer is D. Whitish oval specks sticking to the hair shaft are nits, which are a definitive sign of pediculosis capitis (head lice). A: Scratching the head more than usual is a common symptom but not confirmatory of head lice infestation. B: Flakes evident on a student's shoulders may indicate dandruff or dry scalp, not necessarily head lice. C: Oval pattern occipital hair loss is not a typical manifestation of pediculosis capitis.
2. The clinician is assessing a client with a Stage 2 skin ulcer. Which of the following treatments is most effective to promote healing?
- A. Covering the wound with a dry dressing
- B. Using hydrogen peroxide soaks
- C. Leaving the area open to dry
- D. Applying a hydrocolloid or foam dressing
Correct answer: D
Rationale: Applying a hydrocolloid or foam dressing is the most effective treatment to promote healing for a Stage 2 skin ulcer. These dressings create a moist environment that supports healing and prevents further tissue damage. Option A (covering the wound with a dry dressing) can lead to drying out the wound bed, hindering healing. Option B (using hydrogen peroxide soaks) can be too harsh and may damage the surrounding healthy tissue. Option C (leaving the area open to dry) can delay healing as it does not provide the necessary moist environment for optimal wound healing.
3. When caring for a client who has overdosed on PCP, the nurse should be especially cautious about which of the following client behaviors?
- A. Visual hallucinations
- B. Violent behavior
- C. Bizarre behavior
- D. Loud screaming
Correct answer: B
Rationale: The correct answer is B: 'Violent behavior.' When a client has overdosed on PCP, the nurse should be particularly cautious about the manifestation of violent behavior. PCP overdose can lead to aggressive and unpredictable actions, posing a significant risk to both the client and healthcare providers. Visual hallucinations (choice A), bizarre behavior (choice C), and loud screaming (choice D) can also occur with PCP overdose, but the primary concern should be the potential for violent behavior, making it the most critical behavior to monitor and manage.
4. What is a common sign of dehydration in a child with diarrhea?
- A. Decreased urine output
- B. Increased appetite
- C. Warm, dry skin
- D. Elevated blood pressure
Correct answer: A
Rationale: The correct answer is A: Decreased urine output. When a child with diarrhea is dehydrated, they may have decreased urine output, indicating that their body is conserving fluids. This sign highlights the importance of fluid replacement to prevent worsening dehydration. Choices B, C, and D are incorrect. Increased appetite is not typically associated with dehydration but can be seen in other conditions. Warm, dry skin may be a sign of fever or other skin conditions, not specifically dehydration. Elevated blood pressure is not a common sign of dehydration in a child with diarrhea.
5. What action should the nurse include in the plan of care for a postoperative client with a history of poor nutritional intake who needs care for wound healing?
- A. Provide a protein intake of 1.5 g/kg of body weight per day.
- B. Increase carbohydrate intake to 50% of daily calories.
- C. Administer high-dose vitamin supplements.
- D. Ensure a daily intake of 1000 calories.
Correct answer: A
Rationale: To promote wound healing in a postoperative client with poor nutritional intake, the nurse should include a protein intake of 1.5 g/kg of body weight per day in the plan of care. Proteins are essential for tissue repair and wound healing. Increasing carbohydrate intake or administering high-dose vitamin supplements may not directly promote wound healing. Ensuring a daily intake of 1000 calories may not provide adequate nutrients for optimal wound healing.
