This technique refers to the use of multiple referents to draw conclusions about what constitutes the truth.

Correct Answer: B

Rationale: Triangulation is the technique that refers to the use of multiple referents to draw conclusions about what constitutes the truth. In the context provided in the question, Nurse Tarly is organizing a study to investigate the "Caring behavior of Staff-Nurses and Satisfaction of Women with Ostomy". By gathering data from various sources such as observation, interviews, and surveys, Nurse Tarly can triangulate the information to gain a comprehensive understanding of the situation. Triangulation helps to validate findings, enhance the credibility of the study, and provide a more well-rounded view of the issue at hand.

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: 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: D

Rationale: In this scenario, the patient's presentation of a painless thyroid nodule and hoarseness of voice is consistent with papillary thyroid carcinoma, a type of thyroid cancer. While Hashimoto's thyroiditis and Graves' disease are autoimmune thyroid conditions that can lead to thyroid nodules, they typically do not present with hoarseness of voice. Diabetes mellitus does not directly cause these symptoms. Thyroid cancer, particularly papillary thyroid carcinoma, is the most likely cause based on the patient's clinical presentation and the biopsy results.

Correct Answer: A

Rationale: Betamethasone (Celestone) is a corticosteroid medication that is commonly used to promote fetal lung maturity in pregnant women at risk of preterm delivery. Administering betamethasone to the mother helps accelerate the production of surfactant in the fetal lungs, which is essential for proper lung function and development. This medication is typically given to pregnant women between 24 and 34 weeks of gestation to reduce the risk of respiratory distress syndrome in preterm infants. It does not prevent premature closure of the ductus arteriosus, delay delivery, or stop premature uterine contractions.

Correct Answer: A

Rationale: When a woman in active labor is experiencing intense pain and requests non-pharmacological pain relief measures, the nurse should prioritize providing continuous labor support. Continuous labor support, also known as a doula or labor companion, has been shown to be effective in reducing the perception of pain and improving labor outcomes. The presence of a supportive person can provide physical, emotional, and informational support, helping the woman cope with the pain and navigate through the labor process. This intervention can enhance the woman's overall experience of labor and improve maternal and neonatal outcomes without the need for pharmacological interventions. Administering opioids, performing epidural analgesia, or initiating nitrous oxide inhalation are pharmacological pain relief measures and may not align with the woman's preference for non-pharmacological options.

Correct Answer: D

Rationale: The most appropriate diagnostic examination to confirm the incidence of hypertension among residents is blood pressure (BP) monitoring. Hypertension is defined by elevated blood pressure readings consistently measured over time. Monitoring of blood pressure is essential for diagnosing hypertension and determining the severity of the condition. Chest x-ray, ultrasound, and electrocardiogram are not specific tests for diagnosing hypertension. While these tests may be useful in assessing potential complications or causes of hypertension, they do not directly confirm the presence of high blood pressure. Regular BP monitoring with the use of a sphygmomanometer or automated blood pressure device is crucial in diagnosing and managing hypertension.

Correct Answer: B

Rationale: When a patient with a suspected spinal injury is found unconscious, the priority action is to secure the airway without jeopardizing the cervical spine. A jaw thrust maneuver is the appropriate technique to open the airway in this situation because it allows for the maintenance of neutral alignment of the cervical spine while ensuring proper ventilation. Moving the patient to a flat surface or applying a cervical collar could potentially worsen the spinal injury if not done correctly, and checking for responsiveness should only be done after ensuring a patent airway. Therefore, the safest and most effective initial action is to perform a jaw thrust maneuver to establish a clear airway.

Correct Answer: A

Rationale: Toll-like receptors (TLRs) are a group of cellular receptors responsible for recognizing pathogen-associated molecular patterns (PAMPs), which are molecular components commonly found on pathogens like bacteria and viruses. When TLRs recognize these PAMPs, they initiate signaling pathways that trigger the innate immune response, leading to inflammation, antimicrobial defense, and the activation of adaptive immunity. B cell receptors (BCRs) and T cell receptors (TCRs) are involved in adaptive immune responses and recognize specific antigens rather than PAMPs. Fc receptors primarily bind to the Fc portion of antibodies and are involved in antibody-mediated immune responses. Thus, TLRs specifically play a critical role in sensing and responding to pathogens through the recognition of PAMPs.
