A weakening or wasting away of a muscle is known as

Correct Answer: C

Rationale: The correct answer is C: Atrophy. Atrophy refers to the weakening or wasting away of a muscle due to disuse or disease. Autonomy (A) means self-governance, not related to muscle wasting. Anatomy (B) is the study of the structure of organisms, not muscle atrophy. Autopsy (D) is a postmortem examination, not related to muscle weakening. Therefore, C is the correct answer as it specifically describes the condition of muscle wasting.

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: C

Rationale: The correct answer is C (58 beats per minute) because a normal adult radial pulse rate typically ranges from 60-100 beats per minute. Therefore, a count of 58 would be considered below the normal range. Choices A and B fall within the normal range, while choice D is above the normal range. The abnormality in choice C warrants further investigation as it may indicate bradycardia or other underlying health conditions.

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.
