Correct Answer: A

Rationale: The correct answer is A: Daily intake and output. Monitoring fluid balance involves tracking the amount of fluids taken in and expelled from the body. Intake includes oral, IV, and tube feedings, while output includes urine, vomitus, diarrhea, and any other fluid losses. Daily intake and output provide a comprehensive view of a patient's fluid status, helping identify trends and potential issues. Vital signs (B) provide general information but not specific to fluid balance. Daily weight (C) can fluctuate due to various factors, not just fluid status. Skin turgor (D) is a late sign of dehydration and not as reliable as intake and output monitoring.

Correct Answer: D

Rationale: The correct answer is D: To determine clients response to therapy. Evaluating BUN, creatinine, and serum electrolyte levels in a client being treated for acute pyelonephritis helps the nurse assess the effectiveness of the therapy. Changes in these levels indicate how well the kidneys are functioning and how the client is responding to treatment. Monitoring these parameters allows for adjustments in therapy if needed. Incorrect choices: A: To determine the severity of the disorder - While these tests can provide information about the severity of kidney dysfunction, the primary focus is on monitoring the response to therapy. B: To identify signs of fluid retention - While BUN and creatinine levels can indirectly indicate fluid status, the main purpose of evaluating these tests is to assess therapy response. C: To determine the location of discomfort - These tests do not provide information about the location of discomfort but rather focus on kidney function and response to treatment.

Correct Answer: A

Rationale: The correct answer is A: Secure the cannula with tape. This is the last step in inserting an IV cannula to ensure it stays in place and prevents dislodgement or movement. Securing the cannula with tape helps maintain proper positioning and prevents accidental removal. Documenting the insertion site, date, and type of cannula used (B) is important but typically done earlier in the process. Assessing the site (C) should be done before securing the cannula to ensure proper placement. Placing a sterile dressing over the insertion site (D) is also important, but it usually comes before securing the cannula with tape to maintain a clean and sterile environment.

Correct Answer: B

Rationale: The correct answer is B: A sudden drop in BP may occur during the first 1-3 hours after the initial dose. Angiotensin converting enzyme inhibitors can cause vasodilation, leading to a reduction in blood pressure. In clients with renal or hepatic impairment and in older adults, these medications may not be cleared from the body as efficiently, increasing the risk of hypotension. Monitoring is crucial to prevent complications. Incorrect choices: A: A sudden raise in BP is unlikely with angiotensin converting enzyme inhibitors. C: Angiotensin converting enzyme inhibitors do not affect body temperature. D: Angiotensin converting enzyme inhibitors typically do not cause a sudden rise in pulse rate. In summary, monitoring for a potential drop in blood pressure is essential in vulnerable populations when using angiotensin converting enzyme inhibitors.

Correct Answer: C

Rationale: The correct answer is C: Joint abnormalities. In rheumatoid arthritis, joint abnormalities such as swelling, warmth, and tenderness are the hallmark manifestations. Assessing joint abnormalities first is crucial as they are the primary clinical signs of the disease. Muscle weakness (A) is a common symptom but typically occurs later due to joint inflammation and disuse. Painful subcutaneous nodules (B) are present in some cases but are not as common or prominent as joint abnormalities. Gait disturbances (D) may occur as a result of joint damage, but they are secondary to the primary manifestation of joint abnormalities. By prioritizing the assessment of joint abnormalities, the nurse can promptly identify and address the most prevalent disease manifestations in rheumatoid arthritis.
