Correct Answer: A

Rationale: When a baby is placed on phototherapy, especially for treating jaundice, it is crucial for the nurses to put sunglasses on the newborn to protect their eyes. Phototherapy involves exposing the baby's skin to certain types of light to help break down the bilirubin causing the jaundice. However, this light can be harmful to the baby's sensitive eyes, potentially leading to eye damage or other eye-related issues if not protected adequately. Therefore, placing sunglasses on the newborn is a necessary precaution to ensure the safety and well-being of the baby's eyes during the treatment.

Correct Answer: A

Rationale: Immunological memory is primarily maintained by the clonal expansion of memory B cells. Memory B cells are a type of long-lived immune cell that originates from previously activated B cells during an immune response to a pathogen. When the immune system encounters the same pathogen again, memory B cells can quickly recognize and respond to it by undergoing rapid clonal expansion and differentiation into plasma cells that produce specific antibodies. This quick and robust response leads to the more efficient elimination of the pathogen during secondary exposure, resulting in the faster and stronger immune response characteristic of immunological memory.

Correct Answer: D

Rationale: When a postpartum client exhibits signs of postpartum psychosis such as hallucinations, delusions, and disorganized behavior, it is crucial to involve the healthcare provider immediately. Postpartum psychosis is a psychiatric emergency that requires prompt assessment and intervention by mental health professionals. The healthcare provider can determine the appropriate course of action, which may include hospitalization, medication management, and specialized psychiatric care. Delaying notification can lead to serious consequences for both the client and her infant, so timely intervention is essential in managing postpartum psychosis.

Correct Answer: D

Rationale: Prinzmetal's angina, also known as variant angina, is characterized by episodes of chest pain that occur at rest and are relieved by nitroglycerin. Patients with Prinzmetal's angina may also have transient ST-segment elevation on an electrocardiogram (ECG) during episodes of chest pain. This is due to coronary artery vasospasm, which causes temporary obstruction of blood flow to the heart muscle. Stable angina typically presents with chest pain on exertion that resolves with rest, while unstable angina and acute myocardial infarction present with chest pain that is not relieved with nitroglycerin and are associated with more severe coronary artery disease.

Correct Answer: B

Rationale: When a patient receiving palliative care for end-stage COPD expresses a desire to discuss advance care planning, the palliative nurse should initiate a conversation about advance directives and future care preferences. Advance care planning involves discussing and documenting a patient's preferences regarding future medical care, particularly in situations where the patient may no longer be able to make decisions. This discussion helps ensure that the patient's wishes are respected and followed in the event they are unable to communicate their preferences. By engaging in advance care planning discussions, the nurse can help the patient feel empowered, supported, and in control of their medical care decisions. It also allows healthcare providers to align care with the patient's values and goals, ultimately improving quality of life and ensuring dignity at the end of life.
