1. Which of the following can cause coup-contrecoup injuries?

• A. Rotational forces
• B. Deformation forces
• C. Deceleration forces
• D. Acceleration forces

Correct answer: C

Rationale: Deceleration forces occur when the head is moving and abruptly comes to a stop, such as in a car crash. This sudden deceleration can cause the brain to hit against the skull, resulting in coup-contrecoup injuries. In a coup-contrecoup injury, the brain is damaged on opposite sides due to the initial impact and the rebound effect inside the skull. Rotational forces usually result in diffuse axonal injuries rather than coup-contrecoup injuries. Deformation forces can cause focal brain injuries but not coup-contrecoup injuries. Acceleration forces typically lead to diffuse brain injuries, not coup-contrecoup injuries. Therefore, the correct answer is deceleration forces.

2. After performing an assessment of an infant with bladder exstrophy, the nurse prepares a plan of care. The nurse identifies which problem as the priority for the infant?

• A. Urinary incontinence
• B. Impaired tissue integrity
• C. Inability to suck and swallow
• D. Lack of knowledge about the disease (parents)

Correct answer: B

Rationale: In bladder exstrophy, the bladder is exposed and external to the body, leading to impaired tissue integrity related to the exposed bladder mucosa as the priority problem. Urinary incontinence is not a concern as the infant is not yet toilet trained. Inability to suck and swallow is unrelated to the disorder. While educating the parents about the condition is important, it is not the priority over addressing the immediate risk of impaired tissue integrity in the infant.

3. The nurse provides preoperative instruction for a patient scheduled for a left pneumonectomy for lung cancer. Which information should the nurse include about the patient's postoperative care?

• A. Positioning on the right side
• B. Bed rest for the first 24 hours
• C. Frequent use of an incentive spirometer
• D. Chest tube placement with continuous drainage

Correct answer: C

Rationale: After a pneumonectomy, frequent deep breathing and coughing are essential to prevent atelectasis and promote gas exchange. Patients are typically positioned on the surgical side to aid in gas exchange. Early mobilization is crucial to reduce the risk of postoperative complications such as pneumonia and deep vein thrombosis. While chest tubes may or may not be placed in the surgical space, if used, they are clamped and only adjusted by the surgeon to manage serosanguineous fluid accumulation. Overfilling of the chest cavity can compromise remaining lung function and cardiovascular status. Chest x-rays are useful for monitoring fluid volume and space postoperatively. Therefore, the correct postoperative care instruction for the patient undergoing a left pneumonectomy is the frequent use of an incentive spirometer. Choices A, B, and D are incorrect as positioning on the right side, bed rest for the first 24 hours, and continuous chest tube drainage are not standard postoperative care practices for patients undergoing pneumonectomy.

4. A 16-month-old child has just been admitted to the hospital. As the nurse assigned to this child enters the hospital room for the first time, the toddler runs to the mother, clings to her, and begins to cry. What would be the initial action by the nurse?

• A. Arrange to change client care assignments
• B. Explain that this behavior is expected
• C. Discuss the appropriate use of 'time-out'
• D. Explain that the child needs extra attention

Correct answer: B

Rationale: When encountering a 16-month-old child exhibiting fear of strangers by clinging to the parent and crying, it is essential for the nurse to explain that this behavior is expected. Fear of strangers typically emerges around 6-8 months of age and can continue into the toddler years and beyond. This behavior is a normal part of development as the child is displaying attachment and trust in familiar caregivers. Changing client care assignments, discussing 'time-out,' or suggesting the child needs extra attention are not appropriate initial actions in this situation. Changing care assignments is unnecessary and does not address the child's emotional needs. Discussing 'time-out' is not relevant as it pertains to discipline strategies for older children. Suggesting the child needs extra attention may misinterpret the situation; the child's behavior is a normal response to a new environment and does not necessarily indicate a need for additional attention.

5. An infant weighed 7 pounds 8 ounces at birth. If growth occurs at a normal rate, what would be the expected weight at 6 months of age?

• A. Double the birth weight
• B. Triple the birth weight
• C. Gain 6 ounces each week
• D. Add 2 pounds each month

Correct answer: A

Rationale: Infants typically double their birth weight by 6 months of age as part of normal growth and development. This doubling of weight is a common milestone used by healthcare providers to assess a baby's growth progress. Tripling the birth weight or adding 2 pounds each month would result in excessive weight gain, which is not typical or healthy for an infant. Similarly, gaining 6 ounces each week would also lead to rapid and abnormal weight gain, making it an incorrect choice.
