Which criterion refers-to the ability of the instrument to detect fine differences among the subjects being studied?
- A. Reliability
- B. objectivity
- C. Sensitivity
- D. Validity
Correct Answer: C
Rationale: Sensitivity refers to the ability of an instrument to detect small or fine differences among the subjects being studied. In the context of research or measurement tools, sensitivity is crucial for identifying subtle variations in the data that may hold importance in the analysis. A sensitive instrument can accurately measure and record even the smallest changes, making it a valuable criterion when assessing the quality of a measurement tool in research studies. High sensitivity indicates that the instrument is more likely to pick up on nuances and variations in the data, providing researchers with more detailed and accurate information to work with.

A patient presents with polyuria, polydipsia, and polyphagia. Laboratory tests reveal hyperglycemia and glycosuria. Which endocrine disorder is most likely responsible for these symptoms?
- A. Hyperthyroidism
- B. Hypothyroidism
- C. Diabetes mellitus
- D. Cushing's syndrome
Correct Answer: C
Rationale: The symptoms of polyuria (excessive urination), polydipsia (excessive thirst), and polyphagia (excessive hunger) are classic signs of diabetes mellitus. In this case, the presence of hyperglycemia (high blood sugar) and glycosuria (glucose in the urine) further support the diagnosis of diabetes mellitus. Insulin deficiency or resistance in diabetes leads to impaired glucose utilization and excessive glucose in the bloodstream, causing the classic symptoms observed in the patient. Hyperthyroidism, hypothyroidism, and Cushing's syndrome do not typically present with the hallmark symptoms of polyuria, polydipsia, and polyphagia associated with uncontrolled diabetes mellitus.
Nurse Cris received information from some community residents who suspect that a neighbor ls abusing his young child. Which should be the PRIORITY nursing action ?
- A. Report the police authorities.
- B. Notify the social worker.
- C. Ignore the information
- D. Validate the information

Rationale: The PRIORITY nursing action when receiving information about suspected child abuse is to report to the police authorities. Child abuse is a serious issue that requires immediate intervention to ensure the safety and well-being of the child. The police are trained to investigate these types of situations and can take the necessary steps to protect the child from harm. It is essential to act swiftly and report any suspicions of child abuse to the proper authorities to prevent further harm and ensure the child's safety.
A patient with a history of stroke is at risk for impaired skin integrity due to immobility. Which nursing intervention is most effective in preventing pressure ulcers in this patient?
- A. Turning and repositioning the patient every 2 hours
- B. Massaging bony prominences regularly
- C. Applying heating pads to areas of erythema
- D. Using a pressure-reducing mattress
Correct Answer: A
Rationale: Turning and repositioning the patient every 2 hours is the most effective nursing intervention in preventing pressure ulcers in a patient with a history of stroke and immobility. Pressure ulcers, also known as bedsores, are caused by prolonged pressure on the skin, leading to reduced blood flow and tissue damage. By regularly turning and repositioning the patient, pressure is relieved from specific areas of the body, helping to prevent the development of pressure ulcers. This intervention helps to redistribute pressure, improve blood flow, and reduce the risk of skin breakdown, thus promoting skin integrity in immobile patients.
A patient presents with urinary frequency, urgency, dysuria, and suprapubic pain. Urinalysis reveals pyuria and bacteriuria. Which of the following conditions is most likely?
- A. Acute glomerulonephritis
- B. Chronic kidney disease
- C. Urinary tract infection (UTI)
- D. Renal calculi
Correct Answer: C
Rationale: The patient's presentation of urinary frequency, urgency, dysuria, and suprapubic pain along with the urinalysis findings of pyuria (pus in the urine) and bacteriuria (bacteria in the urine) are highly suggestive of a urinary tract infection (UTI). UTIs are one of the most common types of bacterial infections seen in clinical practice. The symptoms described are classic for a lower urinary tract infection. The presence of pyuria and bacteriuria on urinalysis further supports the diagnosis of a UTI. Acute glomerulonephritis typically presents with hematuria, proteinuria, hypertension, and edema. Chronic kidney disease is often asymptomatic in early stages and presents with symptoms like fatigue, edema, and changes in urination later on. Renal calculi are associated with severe colicky flank pain that can radiate to the groin, and they may present with
A nurse is collaborating with other healthcare providers to develop a plan of care for a patient. What is the primary purpose of interdisciplinary collaboration in nursing practice?
- A. Promoting professional development among healthcare providers
- B. Improving communication and coordination of patient care
- C. Establishing hierarchy and authority within the healthcare team
- D. Reducing workload and increasing efficiency in healthcare delivery
Correct Answer: B
Rationale: The primary purpose of interdisciplinary collaboration in nursing practice is to improve communication and coordination of patient care. When healthcare providers from different disciplines work together as a team, they can share their unique perspectives, knowledge, and skills to develop comprehensive care plans that address all aspects of a patient's well-being. This collaborative approach helps ensure that the patient receives holistic and coordinated care, leading to better outcomes and patient satisfaction. Effective communication and coordination among team members also help prevent errors, reduce duplication of efforts, and promote efficient use of resources. Overall, interdisciplinary collaboration is essential for delivering high-quality, patient-centered care in healthcare settings.
