Exam 3 254 with verified solutions 2024

1. The nurse would call the primary care provider immediately for which laboratory result? 1. Hgb = 16 g/dL for a male client 2. Hct = 22% for a female client 3. WBC = 9 × 103 /mL3 4. Platelets = 300 × 103 /mL3 correct answersAnswer: 2. Rationale: Option 2 is very low and can lead to death. The client's red blood cells participate in oxygenation. Options 1, 3, and 4 are within normal range and should not be reported to the primary care provider. 2. A 78-year-old male client needs to complete a 24-hour urine specimen. In planning his care, the nurse realizes that which measure is most important? 1. Instruct the client to empty his bladder and save this voiding to start the collection. 2. Instruct the client to use sterile individual containers to collect the urine. 3. Post a sign stating "Save All Urine" in the bathroom. 4. Keep the urine specimen in the refrigerator. correct answersAnswer: 3. Rationale: Option 3 is the most important nursing measure. This will inform the staff that the client is on a 24-hour urine collection. Option 1 is not appropriate since the first voided specimen is to be discarded. Option 2 is not an appropriate nursing measure since the specimen container is clean not sterile, and one container is needed—not individual containers. Option 4 is inappropriate because some 24-hour urine collections do not require refrigeration. 3. The client has a urinary health problem. Which procedure is performed using indirect visualization? 1. Intravenous pyelography (IVP) 2. Kidneys, ureter, bladder (KUB) 3. Retrograde pyelography 4. Cystoscopy correct answersAnswer: 2. Rationale: A KUB is an x-ray of the kidneys, ureters, and bladder. This does not require direct visualization. Option 1 is an IVP, an intravenous pyelogram, which requires the injection of a contrast media. Option 3 is a retrograde pyelography, which requires the injection of a contrast media. Option 4 is a cystoscopy, which uses a lighted instrument (cystoscope) inserted through the urethra, resulting in direct visualization.
