Adult Health Nursing Study Guide Answers

Correct Answer: D

Rationale: Escherichia coli (E. coli) is the MOST common causative agent of urinary tract infection (UTI), accounting for approximately 80-85% of all cases. E. coli is a type of bacteria that naturally resides in the gastrointestinal tract and can easily migrate to the urinary tract, causing infection. Its prevalence in UTIs is due to various factors such as its ability to adhere to the uroepithelial cells and form biofilms, leading to persistent infections. Therefore, E. coli is the most common organism responsible for UTIs in both community and healthcare settings.

Correct Answer: D

Rationale: Fats are essential for the absorption of vitamin K in the body. Vitamin K is a fat-soluble vitamin, meaning it is better absorbed in the presence of dietary fats. In the case of postpartum hemorrhage, adequate levels of vitamin K are crucial for proper blood clotting. Thus, incorporating fats in the diet can help ensure sufficient absorption of vitamin K, which can be beneficial in preventing complications related to hemorrhage.

Correct Answer: C

Rationale: Methotrexate is a medication commonly used in the treatment of rheumatoid arthritis. It is known to have potential hepatotoxic effects, meaning it can harm the liver. Monitoring liver function tests (such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), and bilirubin levels) is essential to detect any liver damage early on during methotrexate therapy. By closely monitoring liver function tests, healthcare providers can assess the medication's impact on the liver and determine if any dose adjustments or discontinuation of the drug is necessary to prevent further liver damage. Regular monitoring of liver function tests helps ensure the safe and effective use of methotrexate in patients with rheumatoid arthritis.

Correct Answer: C

Rationale: Ménière's disease is characterized by the triad of symptoms including progressive sensorineural hearing loss, tinnitus, and vertigo. The audiometric testing in Ménière's disease often shows a "carrot-shaped" configuration, which refers to low-frequency hearing loss initially and eventually spreading to involve higher frequencies. This distinctive pattern of hearing loss helps differentiate Ménière's disease from other causes like Presbycusis (age-related hearing loss) or Noise-induced hearing loss. Acoustic neuroma can present with unilateral sensorineural hearing loss but typically does not exhibit the specific "carrot-shaped" configuration seen in Ménière's disease.

Correct Answer: B

Rationale: Carpal tunnel syndrome is a condition caused by compression of the median nerve in the wrist. The surgical procedure commonly performed to treat carpal tunnel syndrome is called median nerve release or carpal tunnel release. During this surgery, the transverse carpal ligament is divided to relieve pressure on the median nerve, reducing symptoms such as pain, numbness, and tingling in the hand and fingers. The goal of this procedure is to improve nerve function and reduce symptoms associated with carpal tunnel syndrome.
