A female resident's perineal area should be cleaned

Correct Answer: C

Rationale: The correct answer is C: From front to back. This method prevents contamination of the urinary tract with bacteria from the anal area, reducing the risk of urinary tract infections. Cleaning from back to front (choice D) can introduce harmful bacteria to the urethra. Using soap (choice A) can disrupt the natural pH and flora of the perineal area. Using a special oil (choice B) is not necessary and may not effectively remove bacteria. Therefore, choice C is the most appropriate and hygienic method for perineal care.

Correct Answer: D

Rationale: The correct answer is D: Ulcerative colitis. This chronic inflammatory disease specifically affects the large intestine or colon, causing ulcers and inflammation in the colon's lining. Malabsorption (A) is a condition where the small intestine cannot absorb nutrients properly. Fecal impaction (B) is a severe constipation issue, not related to chronic inflammation. Crohn's disease (C) is a separate inflammatory bowel disease that can affect any part of the digestive tract, not just the colon. Ulcerative colitis is the only choice that accurately describes a chronic inflammatory disease specific to the large intestine.

Correct Answer: B

Rationale: The correct answer is B because erectile dysfunction is a medical condition that can be effectively treated with medication. Erectile dysfunction is not a normal part of aging (choice A), as it can occur at any age. It is also not incurable (choice C), as there are various treatment options available. Additionally, erectile dysfunction is not related to inflammation of the testes (choice D), which is a separate medical issue. Therefore, choice B is the correct answer as it aligns with the common treatment approach for erectile dysfunction.

Correct Answer: C

Rationale: The correct answer is C: Pernicious anemia. Pernicious anemia is caused by the body's inability to absorb vitamin B12, leading to a deficiency in this essential nutrient. Vitamin B12 is crucial for the production of red blood cells, and its deficiency can result in anemia. Pulmonary edema (A) is excess fluid in the lungs, congestive heart failure (B) is a heart condition, and phlebitis (D) is inflammation of a vein, none of which are directly related to vitamin B12 absorption.

Correct Answer: B

Rationale: The correct answer is B: Yellow or green sputum. Acute bronchitis is characterized by inflammation of the bronchial tubes, leading to increased mucus production. The sputum can appear yellow or green due to the presence of white blood cells, indicating an infection. Coughing up blood (choice A) is more commonly associated with conditions like pneumonia or lung cancer. Night sweats (choice C) are typically seen in conditions like tuberculosis or lymphoma. Excessive urination (choice D) is not a common symptom of acute bronchitis.
