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.

Which is the MOST important risk factor to osteoporosis
- A. Menopause
- B. With history of previous fracture
- C. Being male
- D. Short in height
Correct Answer: A
Rationale: Menopause is the most important risk factor for osteoporosis because it leads to a decrease in estrogen levels, which plays a crucial role in maintaining bone density. After menopause, women are at a higher risk of developing osteoporosis due to loss of estrogen's protective effects on bone mass. Other risk factors like history of previous fracture, being male, and short stature can also contribute to osteoporosis, but menopause has the strongest association with the development of the condition. It is essential for postmenopausal women to be aware of this risk factor and take preventive measures such as regular exercise, adequate calcium and vitamin D intake, and appropriate medical evaluation and treatment as needed.
Which assessment findings is INDICATIVE of the diagnosis of hypertension?
- A. Family members with high blood pressure
- B. Elevation of blood cholesterol level
- C. Stressful work environment
- D. Consistent evaluation of blood pressure
Correct Answer: D
Rationale: The assessment finding that is indicative of the diagnosis of hypertension is consistent evaluation of blood pressure. Hypertension is diagnosed based on repeated measurements of elevated blood pressure. Consistently high blood pressure readings, usually defined as systolic blood pressure consistently at or above 140 mmHg and diastolic blood pressure consistently at or above 90 mmHg, are a key factor in diagnosing hypertension. Family history of high blood pressure (Choice A), elevation of blood cholesterol level (Choice B), and a stressful work environment (Choice C) may be risk factors for hypertension but are not diagnostic criteria. In order to diagnose hypertension, healthcare providers rely on consistent measurement and evaluation of blood pressure over time.
While Mrs. Mely is on TPN she suddenly complained of slight chest pain, dyspnea and appears cyanotic. You suspect that she is experiencing what possible IMMEDIATE complication?
- A. Sepsis due to IV 1ine
- B. Hyperglycemia.
- C. Air embolism
- D. Allergic reaction to TPN
Correct Answer: C
Rationale: The symptoms described in the scenario - chest pain, dyspnea, and cyanosis - are indicative of a potential air embolism. Air embolism occurs when air enters the bloodstream, leading to blockages in blood vessels and impeding oxygen delivery to tissues. In patients receiving Total Parenteral Nutrition (TPN) through intravenous lines, the risk of air embolism exists during line manipulations, disconnections, or improper priming of the tubing. The sudden onset of symptoms like chest pain and cyanosis in a patient on TPN should raise suspicion for an air embolism, as it requires immediate intervention to prevent further complications such as cardiac arrest or stroke.
Bioethical issue should be describe as _____.
- A. the withholding of food and treatment at the request of the patient in a written advance directive given before a patient acquired permanent brain damage from an accident
- B. the physician's making all decisions of client management without getting input from the patient
- C. after the patient gives permission, the physician's disclosing all information to the family for this support in the management of the patient
- D. a research project that included treating all regular employed personnel and not treating all casual employed to compare the outcome of specific drug therapy
Correct Answer: A
Rationale: The bioethical issue described in option A revolves around the concept of advance directives. Advance directives are legal documents that outline a person's wishes regarding medical treatment in the event that they are unable to communicate those wishes themselves. In this scenario, the issue pertains to the withholding of food and treatment based on a written advance directive that was made before the patient suffered permanent brain damage. This raises important ethical considerations about respecting a patient's autonomy and adhering to their previously expressed wishes, even in difficult circumstances. The decision to withhold treatment in such a situation is a complex bioethical issue that needs to be handled carefully while balancing the principles of autonomy and beneficence.
The client being admitted to the oncology unit conveys his wishes regarding resuscitation in the event of cardiopulmonary arrest. The nurse advises the client that it would be in his best interest to obtain which document?
- A. will
- B. Proof of health care power of attorney
- C. living wil l
- D. proxy directive
Correct Answer: C
Rationale: A living will is a legal document that outlines a person's preferences and wishes regarding medical treatment, including resuscitation, in the event they become unable to communicate or make decisions. In this scenario, the client being admitted to the oncology unit wants to convey his wishes regarding resuscitation in case of cardiopulmonary arrest. A living will helps ensure that these wishes are known and respected by healthcare providers and loved ones. While a will addresses how a person's assets should be distributed after death and a health care power of attorney designates someone to make medical decisions on the person's behalf, a living will specifically focuses on healthcare preferences and treatment decisions. A proxy directive is similar to a health care power of attorney, designating someone to make healthcare decisions for the person if they are unable to do so themselves.
