A patient with chronic respiratory failure secondary to severe restrictive lung disease requires long-term oxygen therapy to maintain adequate oxygenation. Which of the following oxygen delivery devices is most appropriate for delivering continuous supplemental oxygen in this patient?

Correct Answer: D

Rationale: The most appropriate oxygen delivery device for a patient with chronic respiratory failure secondary to severe restrictive lung disease requiring continuous supplemental oxygen is a non-rebreather mask. A non-rebreather mask is designed to deliver high-flow oxygen and is typically used for short-term medical treatment in emergency situations or for critically ill patients. It is ideal for providing the highest concentration of oxygen available for inhalation, making it suitable for patients with severe hypoxemia.

Correct Answer: D

Rationale: In a longitudinal study design, the nurse researcher collects data at multiple points over an extended period of time. This design allows for the examination of changes or trends over time within the same group of participants. It helps in understanding the long-term effects and relationships between variables by tracking the same individuals over a prolonged duration. This design is particularly useful in studying developmental patterns, chronic diseases, or long-term treatment outcomes.

Correct Answer: A

Rationale: The right to considerate and respectful care irrespective of socio-economic status is applicable in this case because Mr. Steve is facing financial difficulties in paying for his medical bills. This right ensures that all patients receive proper treatment and care regardless of their ability to pay. It emphasizes that every individual deserves to be treated with dignity and respect, regardless of their financial situation. In Mr. Steve's case, being referred to a social worker due to inability to pay should not impact the quality of care and respect he receives from healthcare providers.

Correct Answer: A

Rationale: The appropriate sequence of steps in the assessment of a conscious trauma patient is the ABCDE approach, which stands for Airway, Breathing, Circulation, Disability, and Exposure.

Correct Answer: A

Rationale: The primary intervention that should be prioritized for managing a catheter-related bloodstream infection (CRBSI) associated with a central venous catheter is to remove the central venous catheter. CRBSI is a serious complication that can lead to severe infections and sepsis. The removal of the catheter is crucial to eliminate the source of the infection and prevent further dissemination of the pathogens into the bloodstream. Once the catheter is removed, the healthcare team can consider other interventions such as administering targeted antibiotics based on culture results, performing blood cultures to identify the causative organism, and implementing sterile dressing changes and catheter care protocols. However, immediate removal of the catheter takes precedence in managing CRBSI to prevent worsening of the infection and improve patient outcomes.

Correct Answer: C

Rationale: The main source of nutrition for the baby during pregnancy is the placenta. The placenta is an organ that develops inside the uterus during pregnancy and provides essential nutrients and oxygen from the mother's blood to the baby through the umbilical cord. It acts as a barrier, protecting the baby from harmful substances while allowing necessary nutrients to pass through. The amniotic fluid serves as a protective cushion for the baby, the uterus provides the space for the baby to grow, and chorionic villi are small, hair-like structures on the placenta that aid in the exchange of nutrients and waste between the mother and the baby. However, the primary source of nutrition for the baby is the placenta, making option C the correct answer in this scenario.

Correct Answer: C

Rationale: The presence of persistent, severe perineal pain along with ecchymosis and swelling of the perineum can indicate a complication such as a hematoma. A hematoma is a collection of blood that can occur in the perineal area postpartum, usually as a result of trauma during delivery. It is essential to notify the healthcare provider immediately to assess the situation, provide appropriate treatment, and prevent further complications. Applying ice packs or administering additional analgesic medication may not address the underlying issue of a possible hematoma, so prompt medical evaluation is crucial in this situation.

Correct Answer: B

Rationale: The presentation of a patient with diabetes mellitus showing symptoms of polyuria, polydipsia, nocturia, and fatigue along with laboratory findings of hyperglycemia, glycosuria, and ketonuria is indicative of diabetic ketoacidosis (DKA). DKA is a serious complication of diabetes characterized by hyperglycemia, metabolic acidosis, and ketosis. The increased glucose levels lead to glycosuria, causing osmotic diuresis resulting in polyuria, polydipsia, and nocturia. The body starts breaking down fats for energy in the absence of sufficient insulin, leading to the production of ketones causing ketonuria. The patient may also experience fatigue due to the metabolic abnormalities present in DKA.

Correct Answer: A

Rationale: When handling information about families in the community, the nurse should consider the principle of confidentiality as ethical. Confidentiality refers to the obligation of healthcare providers to safeguard the privacy of patient information. By maintaining confidentiality, the nurse upholds trust and respect in the nurse-family relationship. This principle ensures that sensitive information shared by families is kept secure and not disclosed without permission, thus respecting their autonomy and promoting open communication in healthcare settings.
