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: D

Rationale: After childbirth, the uterus undergoes involution, which is the process of returning to its pre-pregnant size and location. Initially, the fundus is firm and located at or just below the level of the umbilicus immediately after delivery. Over the next 24 hours, the fundus should gradually decrease in height as involution progresses. By the day after delivery, the nurse would expect the fundal assessment to be in line with the umbilicus or slightly below it, indicating normal involution of the uterus. If the fundus remains high or deviates from this expected progression, further assessment and intervention may be needed to prevent complications such as postpartum hemorrhage.

Correct Answer: C

Rationale: The health care team will try the oral route first for Ms. C for delivering nutrition and fluid because it is the most natural and least invasive method. If the patient is able to tolerate oral intake and has adequate oral intake, it is typically the preferred route. Only if she is unable to meet her nutritional needs orally or has difficulty swallowing, then alternative routes such as nasogastric tube, gastrostomy tube, or intravenous routes may be considered. It's important to promote oral intake whenever possible to maintain the patient's quality of life and prevent complications associated with more invasive methods.

Correct Answer: A

Rationale: Naloxone is a medication used to reverse the effects of an opioid overdose by binding to opioid receptors and displacing the opioids. Administering naloxone intravenously is the recommended intervention for managing a patient with a suspected opioid overdose as it can quickly reverse respiratory depression, sedation, and other effects of opioids. This intervention can be life-saving in cases of opioid overdose and is a critical step in the management of such patients. Providing respiratory support with bag-valve-mask ventilation may be necessary in addition to naloxone administration to ensure adequate oxygenation, but naloxone remains the primary intervention to reverse the effects of opioids. Encouraging the patient to drink fluids rapidly or administering benzodiazepines for sedation are not recommended interventions for managing a suspected opioid overdose.

Correct Answer: A

Rationale: According to RA 9482 or the Anti-Rabies Act of 2007, one of the key components of rabies prevention is to have dogs regularly vaccinated against rabies. This is a crucial step in reducing the risk of rabies transmission from dogs to humans. By ensuring that dogs are vaccinated, the likelihood of rabies exposure is significantly decreased. Additionally, proper vaccination also helps protect the health and well-being of the dogs themselves. Therefore, ensuring regular vaccination of dogs is an applicable and important statement regarding rabies post-exposure prophylaxis as mandated by the law.

Correct Answer: B

Rationale: The clinical scenario described is consistent with a diagnosis of anterior epistaxis due to a prominent vascular lesion located in Little's area, which is an important site for nosebleeds. Silver nitrate cautery is the most appropriate intervention for managing this condition. Silver nitrate cautery is a commonly used method to chemically cauterize and eliminate the friable blood vessels responsible for recurrent epistaxis. It is a cost-effective and minimally invasive technique that can be easily performed in an outpatient setting. Nasal packing with anterior nasal tampons might be considered in cases of severe or refractory epistaxis, but in this scenario, where the source of bleeding is localized and identifiable, silver nitrate cautery is the treatment of choice. Endoscopic cauterization of the sphenopalatine artery and surgical excision of a nasal polyp are unnecessary and overly invasive for the described scenario.

Correct Answer: C

Rationale: The right to anonymity is the basic human right that exists when the subject's identity cannot be linked, even by the researcher, with his or her individual responses. Anonymity ensures that individuals can freely express their thoughts, opinions, and experiences without fear of being identified or facing any consequences. It is crucial in research to protect the privacy and confidentiality of participants, build trust, and encourage honest responses. Anonymity is a fundamental ethical principle in research to safeguard the rights and well-being of participants.

Correct Answer: B

Rationale: When a nurse is delegating tasks to a nursing assistant, the principle that should guide the nurse's delegation decisions is assigning tasks based on the assistant's level of experience (Option B). It is essential to take into consideration the skills, competencies, and experience level of the nursing assistant to ensure that the tasks delegated are suitable for them to perform safely and effectively. Delegating tasks beyond the assistant's level of experience may result in errors, inefficiencies, or compromised patient care. Therefore, matching tasks with the assistant's experience level is crucial in successful delegation and providing quality patient care.
