A patient understands the common causes of urinary tract infection if he or she states the following, EXCEPT:

Correct Answer: C

Rationale: Drinking lots of water at night is actually a good practice for promoting urinary health and preventing urinary tract infections (UTIs). Adequate hydration helps to flush out bacteria from the urinary tract, reducing the risk of infections. Therefore, the statement that drinking lots of water at night might have caused a UTI is incorrect. The other choices describe common causes of UTIs such as holding the urge to urinate, introducing bacteria through instruments or catheters, and poor hygiene practices after defecation.

Correct Answer: C

Rationale: The client is taking Isoniazid and Rifampicin, which are two common first-line medications prescribed for the treatment of tuberculosis. Both of these drugs can potentially cause liver toxicity as a side effect. Therefore, the diagnostic test that is most likely to have an abnormal result if the client is taking these medications is the liver function tests. These tests include parameters such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and bilirubin levels, which can indicate liver damage or dysfunction. Monitoring liver function is essential during treatment with these medications to detect any hepatic adverse effects early and make appropriate management decisions.

Correct Answer: C

Rationale: During the surgical procedure, the circulating nurse, scrub nurse, and nurse first assistant are responsible for keeping track of all instruments, needles, and sponges used. As the surgical incision is being closed, the circulating nurse and the scrub nurse/nurse first assistant conduct a final count of all needles, sponges, and instruments to ensure that nothing is accidentally left inside the patient's body. This is a critical step in preventing retained surgical items (RSI), which can lead to serious complications for the patient. It is part of the standard protocol in the operating room to have these specific personnel take charge of counting and verifying all items before the procedure is concluded.

Correct Answer: B

Rationale: Carbamazepine is a known enzyme inducer, and it can increase the metabolism of other drugs, such as phenytoin (Dilantin). This can lead to lower levels of phenytoin in the blood and potentially reduce its effectiveness. Therefore, patients taking carbamazepine should be monitored for elevated levels of phenytoin to ensure optimal seizure control. Diplopia (double vision), leukocytosis, and adult respiratory distress syndrome are not typically associated with carbamazepine use.

Correct Answer: D

Rationale: During the first 24 hours after a client is diagnosed with Addisonian crisis, it is crucial for the nurse to frequently assess the client's vital signs. Addisonian crisis is a life-threatening condition resulting from acute adrenal insufficiency. Monitoring vital signs such as blood pressure, heart rate, respiratory rate, and temperature can provide valuable information about the client's condition and response to treatment. Changes in vital signs may indicate worsening or improvement in the client's health status, helping the nurse to make timely interventions and adjustments in the client's care plan. Regular assessment of vital signs is essential in managing the client's stability and preventing complications during this critical period.
