Which criterion refers-to the ability of the instrument to detect fine differences among the subjects being studied?

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.

Correct Answer: D

Rationale: Weight reduction is the most important focus in the health teachings provided by the nurse. Maintaining a healthy weight is crucial for overall well-being and can significantly reduce the risk of various health conditions such as heart disease, diabetes, and certain cancers. By emphasizing weight reduction, the nurse can help improve the patient's overall health and quality of life. Jogging a mile a day and vigorous exercise are beneficial for weight management, but it is important to address the root cause of potential health problems which in this case may be excess weight. Moreover, emphasizing the importance of weight reduction does not necessarily mean encouraging extreme dieting; instead, it involves promoting a balanced and healthy approach to eating and physical activity.

Correct Answer: C

Rationale: The central theme of Sr. Callista Roy's theory is adaptation. Roy's Adaptation Model focuses on the individual's ability to adapt to internal and external stimuli in order to maintain health and well-being. The theory emphasizes the interconnectedness of the individual and their environment, highlighting the dynamic process of adaptation in response to stimuli. By focusing on adaptation, Roy's theory guides nursing practice in promoting holistic care that supports individuals in adapting to changes and achieving optimal health outcomes.

Correct Answer: A

Rationale: Myxedema is a severe form of hypothyroidism that is characterized by the accumulation of mucopolysaccharides in subcutaneous and other interstitial tissues. This condition leads to puffiness, swelling, and thickening of the skin, giving it a waxy appearance. Other symptoms of myxedema include fatigue, weight gain, cold intolerance, and hair loss. It is important to recognize and treat myxedema promptly as it can lead to serious complications such as myxedema coma, which is a life-threatening condition requiring immediate medical attention.

Correct Answer: C

Rationale: Erythropoietin-stimulating agents (ESAs) are prescribed to manage anemia in patients with chronic kidney disease. Monitoring the hemoglobin level closely during ESA therapy is crucial to ensure that the treatment is effective in increasing red blood cell production without causing excessive elevation. Hemoglobin levels should be checked regularly to adjust the ESA dosage accordingly and prevent risks associated with high hematocrit levels, such as increasing blood viscosity and cardiovascular events. Monitoring serum potassium, creatinine, and platelet count are important in the management of chronic kidney disease for different reasons, but for ESA therapy, monitoring hemoglobin is the most essential parameter.

Correct Answer: D

Rationale: While urinalysis can provide valuable information about a person's health status and can be part of a clinical assessment, it is not typically considered a common screening test for specific diseases or conditions. The other options listed - Pap smears for cervical cancer screening, cholesterol levels for heart disease screening, and PSA levels for prostate cancer screening - are all commonly used screening tests aimed at early detection of specific diseases. Urinalysis is more commonly used as part of a broader health assessment or diagnostic evaluation rather than a dedicated screening tool for a specific condition.

Correct Answer: D

Rationale: The ethical principle of beneficence, which is the basis of every nursing action in all work settings, emphasizes the importance of doing good at all times for the benefit of the patient. Nurses are expected to act in the best interest of their patients and strive to promote their well-being and welfare. This principle guides nurses to provide care that is compassionate, effective, and in line with the patient's needs and preferences. By prioritizing the good of the patient in all actions and decisions, nurses uphold the principle of beneficence and demonstrate their commitment to promoting positive outcomes for those under their care.

Correct Answer: A

Rationale: Atopic dermatitis is a chronic, pruritic inflammatory skin condition that typically presents in individuals with a personal or family history of asthma and allergic rhinitis (hay fever). The characteristic presentation includes erythematous papules, vesicles, and excoriations on the flexural surfaces of the elbows and knees. This type of dermatitis is commonly seen in patients with atopy, which refers to a genetic predisposition to develop allergic diseases like asthma, hay fever, and eczema. Therefore, given the patient's personal history of asthma and hay fever along with the described rash distribution and appearance, atopic dermatitis is the most likely diagnosis.

Correct Answer: A

Rationale: When a baby is placed on phototherapy, especially for treating jaundice, it is crucial for the nurses to put sunglasses on the newborn to protect their eyes. Phototherapy involves exposing the baby's skin to certain types of light to help break down the bilirubin causing the jaundice. However, this light can be harmful to the baby's sensitive eyes, potentially leading to eye damage or other eye-related issues if not protected adequately. Therefore, placing sunglasses on the newborn is a necessary precaution to ensure the safety and well-being of the baby's eyes during the treatment.
