The nurse is examining 12-month-old Amy, who was brought to the clinic for persistent diaper rash. The nurse finds perianal inflammation with satellite lesions that cross the inguinal folds. What is most likely the cause of the diaper rash?

Correct Answer: B

Rationale: The presentation of perianal inflammation with satellite lesions that cross the inguinal folds is highly suggestive of a Candida albicans (yeast) diaper rash. Yeast diaper rash is characterized by redness, swollenness, and usually involves the skin folds. The warm, moist environment created by a diaper provides an ideal setting for Candida albicans to grow and cause a rash. The presence of satellite lesions that cross the inguinal folds further supports the diagnosis of a yeast infection rather than other causes like impetigo, irritation from urine and feces, or infrequent diapering. Treatment for yeast diaper rash typically involves antifungal creams or ointments.

Correct Answer: D

Rationale: Huntington's disease is a progressive neurological disorder that affects movement, cognition, and behavior. The three main clinical manifestations of Huntington's disease are abnormal involuntary movements (chorea), intellectual decline, and emotional disturbances. Chorea is characterized by involuntary jerky movements that are often random and unpredictable. Intellectual decline includes difficulties with cognitive functions such as planning, organizing, and remembering. Emotional disturbances may manifest as irritability, depression, anxiety, or mood swings. Overall, individuals with Huntington's disease experience a wide range of symptoms that impact both their physical and mental well-being.

Correct Answer: B

Rationale: Increased urine osmolarity would best support the nursing diagnosis of Deficient fluid volume in a client with hyperglycemia. Hyperglycemia can lead to osmotic diuresis, where the body excretes excessive amounts of water to help eliminate glucose. This results in concentrated urine with a higher osmolarity. A high urine osmolarity indicates that the kidneys are conserving water due to decreased fluid volume in the body, supporting the diagnosis of Deficient fluid volume. The other assessment findings (cool, clammy skin, distended neck veins, serum sodium level) are not specific to the diagnosis of Deficient fluid volume in this context.

Correct Answer: D

Rationale: In stable asthmatic patients, additional interventions like systemic steroids or increased beta-agonist doses are not always necessary unless there are signs of exacerbation.

Correct Answer: B

Rationale: The term that best describes the identification of the distribution and causes of disease, injury, or illness is the epidemiologic process. Epidemiology is the study of the patterns, causes, and effects of health and disease conditions in populations. Through the epidemiologic process, health professionals can investigate and understand the distribution of diseases, determine risk factors, and develop strategies for prevention and control. Nursing process refers to the systematic method nurses use to provide patient-centered care. Community-based statistics are data collected from a specific community for various purposes. Mortality and morbidity statistics provide information on deaths and disease rates but do not encompass the comprehensive approach of the epidemiologic process in understanding the causes and distribution of diseases.
