Nokea
Which best describes a full-thickness (third-degree) burn?
- A. Erythema and pain
- B. Skin showing erythema followed by blister formation
- C. Destruction of all layers of skin evident with extension into subcutaneous tissue
- D. Destruction injury involving underlying structures such as muscle, fascia, and bone
Correct Answer: C
Rationale: The correct answer is C: Full-thickness burns involve the destruction of all layers of skin, extending into the subcutaneous tissue. This type of burn causes severe damage and loss of sensation due to nerve destruction. Choice A, erythema and pain, describes superficial burns (first-degree). Choice B, skin showing erythema followed by blister formation, describes partial-thickness burns (second-degree). Choice D, destruction injury involving underlying structures such as muscle, fascia, and bone, goes beyond the description of full-thickness burns.

During the second week of hospitalization for intravenous antibiotic therapy, a 2-year-old toddler whose family is unable to visit often smiles easily, goes to all the nurses happily, and does not express interest in the parent when the parent does visit. The parent tells the nurse, 'I am pleased about the adjustment but somewhat concerned about my child's reaction to me.' How should the nurse respond?
- A. The child is repressing feelings towards the parent.
- B. Routines have been established, and the child feels safe.
- C. The child has given up fighting and accepts the separation.
- D. Behavior has improved because the child feels better physically.
Correct Answer: C
Rationale: The correct answer is C. The child's behavior of smiling easily, interacting happily with nurses, and showing disinterest in the parent when they visit indicates that the child has emotionally withdrawn and accepted the separation. This response suggests that the child may have given up fighting against the separation from the parent due to prolonged hospitalization. Choices A, B, and D are incorrect. Choice A about the child repressing feelings towards the parent is not supported by the scenario. Choice B about routines and feeling safe does not address the emotional aspect of the child's behavior. Choice D about improved behavior due to feeling better physically does not explain the emotional dynamics at play in the child's behavior.
An 8-year-old child with the diagnosis of meningitis is to have a lumbar puncture. What should the nurse explain is the purpose of this procedure?
- A. To measure the pressure of cerebrospinal fluid
- B. To obtain a sample of cerebrospinal fluid for analysis
- C. To relieve intracranial pressure
- D. To assess the presence of infection in the spinal fluid
Correct Answer: B
Rationale: The primary purpose of a lumbar puncture is to obtain a sample of cerebrospinal fluid for analysis. This sample helps in diagnosing conditions such as meningitis by evaluating the presence of pathogens or abnormalities in the cerebrospinal fluid. Measuring the pressure of cerebrospinal fluid (Choice A) is not the main objective of a lumbar puncture, although it can be done during the procedure. Relieving intracranial pressure (Choice C) is not the direct purpose of a lumbar puncture, as other interventions are typically used for this purpose. Assessing the presence of infection in the spinal fluid (Choice D) is related to the overall goal of obtaining a sample for analysis, making it a secondary outcome of the procedure.
A 6-month-old infant is admitted with a diagnosis of respiratory syncytial virus (RSV). What should the nurse include in the care plan?
- A. Providing small, frequent feedings
- B. Administering antibiotics
- C. Maintaining strict isolation
- D. Elevating the head of the bed
Correct Answer: D
Rationale: Elevating the head of the bed is essential in the care of an infant with RSV as it helps improve breathing by reducing congestion and promoting drainage. This position also aids in maintaining patent airways and can enhance comfort for the infant. Providing small, frequent feedings (Choice A) is generally appropriate for infants but is not a specific intervention for RSV. Administering antibiotics (Choice B) is not indicated for RSV, as it is a viral infection and antibiotics are ineffective against viruses. Maintaining strict isolation (Choice C) is important to prevent the spread of infections, but it is not a direct care intervention for managing RSV symptoms.
What explanation should be given to a parent about the purpose of a tetanus toxoid injection for their child?
- A. Passive immunity is conferred for life.
- B. Long-lasting active immunity is conferred.
- C. Lifelong active natural immunity is conferred.
- D. Passive natural immunity is conferred temporarily.
Correct Answer: B
Rationale: The correct answer is B: 'Long-lasting active immunity is conferred.' Tetanus toxoid injection provides long-lasting active immunity by stimulating the body to produce its own antibodies. Choice A is incorrect because tetanus toxoid injection does not provide passive immunity. Choice C is incorrect because the immunity conferred by the vaccine is not natural but artificially induced. Choice D is incorrect as the immunity provided by the tetanus toxoid injection is active, not passive.
A 6-year-old with muscular dystrophy was recently injured falling out of bed at home. What intervention should the nurse suggest to prevent further injury?
- A. Recommend raising the bed's side rails when a caregiver is not present.
- B. Suggest a caregiver be present continuously to prevent falls from bed.
- C. Encourage the use of loose restraints while in bed.
- D. Recommend raising the bed's side rails throughout the day and night.
Correct Answer: A
Rationale: In this scenario, the most appropriate intervention to prevent further injury is to raise the bed's side rails when a caregiver is not present. This measure helps in preventing falls without the need for constant supervision. Choice B is not practical as continuous caregiver presence may not always be feasible. Choice C is unsafe as loose restraints can pose a strangulation risk. Choice D does not address the need for intervention when a caregiver is absent, potentially leading to an increased risk of falls.
