The nurse is caring for a preterm newborn who requires mechanical ventilation for the treatment of respiratory distress syndrome. What is the preterm newborn at increased risk of due to the mechanical ventilation?

Correct Answer: A

Rationale: Preterm newborns who require mechanical ventilation are at increased risk of developing alveolar rupture. The pressure from mechanical ventilation can lead to overdistension of the alveoli, causing damage to their delicate structure. This can result in the rupture of the alveolar walls, leading to a condition known as pulmonary interstitial emphysema. Alveolar rupture can contribute to the development of other complications such as pneumothorax and air leaks, which can further compromise the newborn's respiratory status. Therefore, close monitoring and adjustment of ventilation parameters are crucial in the care of preterm newborns on mechanical ventilation to minimize the risk of alveolar rupture and its associated complications.

Correct Answer: A

Rationale: Performing monthly breast self-examination (BSE) after menstruation is recommended because during this time, the breasts are less likely to be swollen or tender, which can help to ensure a more accurate examination. Engaging in BSE on a regular basis can help individuals become familiar with their breast tissue and better recognize any changes that may occur. By performing BSE monthly after menstruation, individuals can actively monitor their breast health and potentially detect any abnormalities or signs of breast cancer at an early stage.

Correct Answer: C

Rationale: An important nursing consideration when caring for a child with herpetic gingivostomatitis (HGS) is to wait to brush teeth until lesions are sufficiently healed. This is because brushing teeth while the lesions are present can be painful and potentially disruptive to the healing process. It is important to ensure that the child is comfortable and that the healing of the lesions is not impeded by brushing too early. This consideration helps promote optimal healing and comfort for the child with this condition.

Correct Answer: B

Rationale: Slow-wave sleep is primarily restorative, not protective against brain injury.

Correct Answer: A

Rationale: Painless hematuria, which is the presence of blood in the urine without any associated pain, is an early indicator of bladder cancer. This symptom is often one of the first signs of this type of cancer and should be promptly evaluated by a healthcare provider. It is crucial not to ignore the presence of blood in the urine, as it can indicate various underlying conditions, including bladder cancer. While other symptoms like Nocturia (waking up at night to urinate), Occasional polyuria (increased urination), and Dysuria (painful urination) can also occur with bladder cancer, painless hematuria is a significant red flag for the disease.
