Gloria decides to include only nurses who have a minimum three years experience as psychiatric nurses. Which of the following terms refer to this?

Correct Answer: D

Rationale: A delimitation in a research study refers to setting specific boundaries or restrictions on the scope of the study. In this scenario, Gloria's decision to include only nurses with a minimum of three years experience as psychiatric nurses is a delimitation because it sets a specific criterion or boundary for the selection of participants. This helps to focus the study on a particular group of individuals who possess the required experience, ensuring the research is targeted and relevant to the topic being investigated.

Correct Answer: A

Rationale: Zenker's diverticulum is a condition in which there is a pouch or sac that forms at the posterior pharyngeal wall above the upper esophageal sphincter. It can present with symptoms such as sensation of a foreign body stuck in the throat, difficulty swallowing (dysphagia), and odynophagia (painful swallowing). Flexible laryngoscopy can reveal a submucosal mass arising from the posterior pharyngeal wall, which is characteristic of Zenker's diverticulum.

Correct Answer: D

Rationale: A patient with chronic kidney disease prescribed a low-protein diet should avoid high-protein foods like grilled salmon, lentil soup, and beef stew. Chicken Caesar salad, on the other hand, typically contains a smaller amount of protein compared to the other options. This choice indicates an understanding of the need to limit protein intake while still enjoying a balanced meal. However, it is important to note that the quantity and portion sizes of high-protein ingredients in the salad should also be moderate to comply with a low-protein diet.

Correct Answer: C

Rationale: The barrier to goal setting between the nurse and the family in this scenario is the failure of the family to perceive the existence of the problem. Goal setting in healthcare generally requires mutual agreement and understanding between the healthcare provider (nurse) and the patient/family. If the family does not perceive that there is an existing problem that needs to be addressed, there will likely be resistance or lack of motivation to set goals and work towards resolving the issue. This barrier can hinder effective communication, collaboration, and ultimately, the successful achievement of healthcare goals. It is important for the nurse to address this barrier through education, communication, and building trust to ensure that all parties are on the same page and actively participate in goal setting and care planning.

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: D

Rationale: The first step Nurse Gabriela should do when handling vaccines is to check the vial for the expiration date. It is crucial to ensure that the vaccine has not expired before proceeding with any further steps. Administering an expired vaccine can be ineffective or even harmful to the patient. Therefore, checking the expiration date is the foundational step in the safe and proper administration of vaccines.

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: Confirmability is the criteria of trustworthiness that refers to the degree to which the findings of a study are based on the data itself and not on the biases, motivations, or interests of the researchers. In this scenario, returning to the participants to confirm the accuracy of the emerged themes is a way to ensure the confirmability of the study findings. By involving the participants in the validation process, the researchers are seeking to verify that the themes identified truly reflect the experiences of the pregnant women in labor as reported by the participants. This practice enhances the credibility and trustworthiness of the study's findings by confirming their alignment with the participants' perspectives and experiences.

Correct Answer: C

Rationale: The PRIORITY nursing action of the nurse for Jose due for oxygen therapy is to turn on the oxygen. Ensuring that the oxygen is turned on is the necessary first step before any other actions can be effective in delivering oxygen to the patient. Without oxygen being turned on, all other steps such as attaching the humidifier, connecting tubing, or adjusting the flow rate would be ineffective in providing the necessary oxygen therapy to the patient. Therefore, turning on the oxygen is the most crucial initial step to take in this situation to ensure that the patient receives the needed oxygen promptly and safely.
