Question 1 of 9
A patient presents with a sensation of fullness and pressure in the left ear, along with hearing loss and occasional tinnitus. Otoscopic examination reveals a retracted tympanic membrane with decreased mobility on pneumatic otoscopy. Which of the following conditions is most likely responsible for this presentation?
Correct Answer: C
Rationale: The presentation described with a sensation of fullness and pressure in the left ear, along with hearing loss and occasional tinnitus, and the findings of a retracted tympanic membrane with decreased mobility on pneumatic otoscopy are most consistent with serous otitis media, also known as otitis media with effusion (OME). OME is characterized by the presence of non-infected fluid in the middle ear space, leading to symptoms such as ear fullness, hearing loss, and occasionally tinnitus.
Question 2 of 9
A patient with systemic lupus erythematosus (SLE) demonstrates a positive antinuclear antibody (ANA) test and elevated levels of anti-double-stranded DNA (anti-dsDNA) antibodies. Which of the following mechanisms is most likely responsible for the production of these autoantibodies?
Correct Answer: A
Rationale: The development of autoantibodies such as antinuclear antibodies (ANA) and anti-double-stranded DNA (anti-dsDNA) antibodies in systemic lupus erythematosus (SLE) is primarily attributed to a loss of self-tolerance. Self-tolerance refers to the immune system's ability to recognize and differentiate self-antigens from foreign antigens. In individuals with SLE, there is a breakdown in immune tolerance mechanisms, leading to the production of autoantibodies against self-antigens like nuclear components (e.g., DNA, RNA, histones). This loss of self-tolerance results in the immune system targeting and attacking its tissues, leading to the systemic inflammation and tissue damage characteristic of SLE. The presence of elevated levels of ANA and anti-dsDNA antibodies in this patient suggests an autoimmune response against nuclear material, further supporting the role of self-tolerance breakdown in SLE
Question 3 of 9
The first standard-step-in oxygen therapy that the nurse should do is which of the following?
Correct Answer: D
Rationale: Before initiating any oxygen therapy, it is crucial for the nurse to first assess the patient's condition. This step allows the nurse to determine the patient's oxygen saturation levels, respiratory rate, lung sounds, and overall respiratory status. Understanding the patient's baseline condition helps in selecting the appropriate oxygen delivery method and flow rate that will best meet the patient's needs. Additionally, assessing the patient's condition allows the nurse to monitor the effectiveness of the oxygen therapy and make any necessary adjustments throughout the treatment process. Therefore, assessing the patient's condition is the necessary first step in providing safe and effective oxygen therapy.
Question 4 of 9
Clients who are taught a variety of skills such as measuring blood glucose, taking blood pressure, changing dressings, and bathing infants belong to which domain of learning?
Correct Answer: A
Rationale: Clients who are taught skills such as measuring blood glucose, taking blood pressure, changing dressings, and bathing infants are learning skills that involve physical movement and coordination. These activities require the integration of mental and physical skills, and they fall under the psychomotor domain of learning. In this domain, individuals develop physical skills and coordination through practice and repetition. The psychomotor domain is one of the three domains of learning, along with the cognitive domain (which involves knowledge and intellectual skills) and the affective domain (which involves emotions, values, and attitudes).
Question 5 of 9
A patient is admitted with a suspected myocardial infarction. Which cardiac biomarker is most specific for myocardial injury?
Correct Answer: A
Rationale: Troponin is the most specific cardiac biomarker for myocardial injury. Troponin I and Troponin T are proteins released into the bloodstream when there is damage to the heart muscle, making them highly indicative of myocardial infarction. Troponin levels rise within a few hours of cardiac injury, peak within 24-48 hours, and can remain elevated for up to 2 weeks. Troponin is considered the gold standard biomarker for the diagnosis of acute myocardial infarction due to its high specificity and sensitivity for cardiac injury. In contrast, Creatine kinase-MB (CK-MB) and myoglobin are also used in diagnosing myocardial infarction but are less specific than troponin. Brain natriuretic peptide (BNP) is primarily used in heart failure diagnosis and management, and its levels are not specific to myocardial injury.
Question 6 of 9
During the postpartum assessment, a new mother reports experiencing mild cramping and uterine contractions while breastfeeding. What physiological process is responsible for these symptoms?
Correct Answer: B
Rationale: Oxytocin release is responsible for the mild cramping and uterine contractions experienced by the new mother while breastfeeding. When a baby suckles at the breast, it stimulates nerve endings that signal the release of oxytocin from the posterior pituitary gland. Oxytocin is a hormone that plays a crucial role in stimulating the contraction of the uterine muscles, helping the uterus to contract back to its pre-pregnancy size. This process, known as uterine involution, is essential for postpartum recovery and preventing excessive bleeding. Therefore, the new mother's experience of mild cramping and uterine contractions while breastfeeding is a normal physiological response mediated by the release of oxytocin.
Question 7 of 9
Falls are one of the leader environmental hazards reported in health facilities. One of the MOST common occurrences that precipitate a patient fall is
Correct Answer: B
Rationale: Leaving the side rails down is one of the most common occurrences that can lead to a patient fall. Side rails are important safety measures designed to prevent patients from falling out of bed. When the side rails are left down, the patient is at a higher risk of accidentally rolling out of bed and falling. It is crucial for healthcare providers to always ensure that the side rails are up and secure to help prevent patient falls.
Question 8 of 9
A woman in active labor has been diagnosed with placenta previa. What is the priority nursing intervention?
Correct Answer: A
Rationale: In the case of a woman in active labor with placenta previa, the priority nursing intervention is to prepare for an immediate cesarean section. Placenta previa is a condition in which the placenta covers part or all of the cervix, which can lead to severe bleeding during labor and delivery. The risk of hemorrhage is significant, making a cesarean section the safest option for both the mother and the baby in this situation. It is crucial to act promptly to prevent complications and ensure the well-being of both the mother and the baby. Administering intravenous oxytocin to augment labor or inserting a Foley catheter to monitor urine output would not address the immediate risk of hemorrhage associated with placenta previa. Implementing bed rest and continuous fetal monitoring may be part of the overall care plan but not the priority intervention in this urgent situation.
Question 9 of 9
A patient presents with sudden-onset severe headache, vomiting, and altered mental status. Imaging reveals a berry-shaped aneurysm at the junction of the anterior communicating artery and anterior cerebral artery. Which of the following neurological conditions is most likely responsible for these symptoms?
Correct Answer: D
Rationale: The presentation of sudden-onset severe headache, vomiting, and altered mental status, along with the presence of a berry-shaped aneurysm on imaging, point towards a diagnosis of subarachnoid hemorrhage. The most common cause of a subarachnoid hemorrhage is the rupture of a saccular (berry) aneurysm, which commonly occurs at the junction of the anterior communicating artery and anterior cerebral artery. The sudden headache is often described as the "worst headache of my life" and is typically associated with nausea and vomiting. Altered mental status may be present due to the effects of increased intracranial pressure and possible associated brain injury. It is important to promptly diagnose and manage subarachnoid hemorrhage to prevent complications such as vasospasm, rebleeding, and ischemic deficits.
