Correct Answer: C

Rationale: Positioning the car seat at a 45-degree angle is correct to ensure the newborn's airway remains open and to reduce the risk of positional asphyxia, as recommended by car seat safety guidelines.
Choice A is wrong because the car seat should never be placed in the front passenger seat, even with the airbag off, due to the risk of injury from airbag deployment or other crash dynamics; the rear seat is safest.
Choice B is wrong because infants should remain in a rear-facing car seat until at least 2 years of age or until they exceed the car seat's height/weight limits, not forward-facing before 1 year.
Choice D is wrong because for rear-facing car seats, the harness straps should be at or below the infant's shoulders to provide proper support and prevent injury during a crash.

Correct Answer: C

Rationale: Verifying the client's identity with two nurses before starting the transfusion is a critical safety measure to prevent transfusion errors, such as administering blood to the wrong client, which can lead to severe complications like hemolytic reactions.
Choice A is wrong because checking the client's temperature 1 hour after the transfusion is not a standard requirement; temperature should be monitored before, during (especially the first 15 minutes), and at the completion of the transfusion to detect febrile reactions.
Choice B is wrong because infusing packed RBCs over 6 hours exceeds the recommended time frame (typically 2-4 hours) and increases the risk of bacterial contamination or hemolysis.
Choice D is wrong because administering a diuretic prior to the transfusion is not routinely indicated unless the client has a specific condition like heart failure or fluid overload, which would be determined by the provider.

Correct Answer: A

Rationale: Monitoring heart rate is essential with metoprolol due to risk of bradycardia. Glucose, potassium, and urine output are less directly affected.

Correct Answer: C

Rationale:
Choice A is wrong because the nurse should not hold the hand flat to perform percussions on the child. Percussions are rhythmic clapping on the chest wall to loosen the mucus. The nurse should use a cupped hand to create a small air pocket that enhances the vibrations and prevents bruising.
Choice B is wrong because the nurse should not perform the procedure twice a day. The recommended frequency of postural drainage is 3 to 4 times a day, or more if needed, depending on the child's condition and tolerance. This is because postural drainage involves positioning the child in different ways to help drain the mucus from the lungs. If the child has a full stomach, this can cause nausea, vomiting, or aspiration.
Therefore, the nurse should perform the procedure before meals or at least 1 hour after meals.
Choice D is wrong because the nurse should not administer a bronchodilator after the procedure. A bronchodilator is a medication that relaxes and widens the airways, making it easier to breathe. The nurse should administer a bronchodilator before the procedure to enhance the effectiveness of postural drainage.

Correct Answer: A

Rationale: This is because boundaries can help the client and family to respect each other's roles, needs, and preferences, and to avoid role confusion, resentment, or guilt. Boundaries can also promote independence and self-care for the client, as well as prevent caregiver burnout for the family.
Choice B is wrong because minimizing open discussion regarding the changes can lead to misunderstanding, frustration, or isolation. The client and family should communicate openly and honestly about their feelings, expectations, and challenges to foster mutual understanding and support.
Choice C is wrong because encouraging authoritative communication from the adult child can create a power imbalance and undermine the client's autonomy and dignity. The client and family should use collaborative and respectful communication to make decisions and solve problems together.
Choice D is wrong because decreasing socialization with extended relatives until roles are identified can isolate the client and family from their social support network. Socialization with extended relatives can provide emotional, practical, and informational support, as well as a sense of belonging and identity for the client and family.
