Nurse Bea reviewed the elements of nursing as a profession. Which of the following is an IMPORTANT element that characterizes Nursing as a profession ?
- A. Has members
- B. Possess body of knowledge
- C. Service oriented
- D. A calling
Correct Answer: B
Rationale: Possessing a body of knowledge is an important element that characterizes nursing as a profession. Nursing is a field that requires specialized education, training, and expertise in various areas of healthcare. Nurses are expected to have a comprehensive understanding of anatomy, physiology, pharmacology, and various nursing theories and practices to effectively care for patients. This body of knowledge distinguishes nursing as a profession and supports the delivery of high-quality, evidence-based patient care. While the other options (having members, being service-oriented, and a calling) are also important aspects of nursing, possessing a body of knowledge is fundamental to the profession's identity and practice.

Which of the following statements accurately describes the role of natural killer (NK) cells in the immune response?
- A. NK cells directly kill virus-infected cells and tumor cells.
- B. NK cells produce antibodies against pathogens.
- C. NK cells present antigens to T cells to initiate adaptive immunity.
- D. NK cells release cytokines to recruit other immune cells to the site of infection.
Correct Answer: A
Rationale: Natural killer (NK) cells play a vital role in the innate immune response by identifying and eliminating virus-infected cells, as well as tumor cells, without the need for prior exposure or activation. NK cells are able to detect abnormal cells by recognizing changes in the cell surface molecules, such as downregulation of MHC class I molecules. Once activated, NK cells release cytotoxic granules containing perforin and granzyme, leading to the destruction of the target cell. This direct killing mechanism is crucial for controlling viral infections and preventing the development of tumors. NK cells do not produce antibodies (option B), present antigens to T cells (option C), or release cytokines to recruit other immune cells (option D) as their primary function in the immune response.
A patient presents with fever, chills, and costovertebral angle tenderness. Urinalysis reveals pyuria and bacteriuria. Which of the following conditions is most likely?
- A. Acute pyelonephritis
- B. Chronic kidney disease
- C. Urinary tract infection (UTI)
- D. Renal calculi
Correct Answer: A
Rationale: Acute pyelonephritis is the most likely condition based on the patient presentation and urinalysis findings described. Acute pyelonephritis is an infection of the renal parenchyma and pelvis, typically caused by ascending bacteria from the lower urinary tract. The classic symptoms include fever, chills, flank pain, and costovertebral angle tenderness (tenderness over the kidneys). The presence of pyuria (pus in the urine) and bacteriuria (bacteria in the urine) on urinalysis further supports the diagnosis of acute pyelonephritis. It is crucial to diagnose and treat acute pyelonephritis promptly to prevent complications and recurrent infections.
It a medicine is unavailable and therefore not given to the patient, how is it charted?
- A. Leave it blank.
- B. Sign and make an explanation in the Nurses Notes.
- C. With an asterisk or mark, as per hospital protocol.
- D. Write the letter.
Correct Answer: B
Rationale: When a medication is unavailable and therefore not given to the patient, it is important to document this in the Nurses Notes along with an explanation. Leaving it blank (Option A) may lead to confusion or errors as the reason for not administering the medication would not be clear. Using an asterisk or mark as per hospital protocol (Option C) may not provide enough information about why the medication was missed. Writing the letter (Option D) without any explanation would not suffice in terms of documentation and accountability. Therefore, signing and making an explanation in the Nurses Notes (Option B) is the correct way to chart when a medication is unavailable. This ensures proper documentation of the situation and helps in maintaining the continuity of care for the patient.
A profession is characterized by the following except:
- A. Body of knowledge
- B. Code of ethics
- C. member of professional organization
- D. Engages in research
Correct Answer: C
Rationale: A profession is characterized by having a body of knowledge, a code of ethics, and engaging in research. However, being a member of a professional organization is not a defining characteristic of a profession. While many professionals may choose to join professional organizations for networking, support, and career advancement reasons, membership in such organizations is not universally required or exclusive to being considered a professional in a particular field. Hence, the presence or absence of professional organization membership does not determine the professional status of an individual.
A woman in active labor is diagnosed with uterine rupture, resulting in fetal distress and maternal hemorrhage. What nursing intervention is essential in managing this obstetric emergency?
- A. Initiating immediate oxytocin infusion
- B. Preparing for immediate instrumental delivery
- C. Performing an emergency cesarean section
- D. Administering intravenous magnesium sulfate
Correct Answer: C
Rationale: Uterine rupture is a severe obstetric complication that requires prompt and decisive management to prevent adverse outcomes for both the mother and the baby. In cases of uterine rupture leading to fetal distress and maternal hemorrhage, performing an emergency cesarean section is crucial. This intervention allows for rapid delivery of the baby, relieving the distress on the fetus and enabling immediate access to manage the maternal hemorrhage. By performing a timely cesarean section, healthcare providers can expedite the delivery process and effectively address both the fetal and maternal complications associated with uterine rupture. This intervention is essential in saving lives and reducing the risk of further complications in such a critical obstetric emergency.
