A client is being treated for chronic kidney disease (CKD). On examination, the client has an elevated blood pressure (BP) and is exhibiting changes in mental status. Which intervention in the plan of care should the practical nurse (PN) implement?

- Urinary output is an important indicator of fluid balance and kidney function. After delivery, a woman may experience increased urinary output due to the loss of excess fluid that was retained during pregnancy and the diuretic effect of oxytocin, which is released during breastfeeding. This is a normal and expected finding in the postpartum period.

- However, increased urinary output may also be a sign of urinary retention, which is the inability to empty the bladder completely. Urinary retention can occur due to trauma to the bladder or urethra during delivery, swelling or hematoma of the perineum, epidural anesthesia, or decreased bladder sensation. Urinary retention can lead to complications such as infection, bladder distension, or postpartum hemorrhage.

- Therefore, when a woman who delivered a normal newborn 24 hours ago reports that she seems to be urinating every hour or so, the practical nurse (PN) should measure the next voiding, and then palpate the client's bladder. This will help to assess the amount and quality of urine and the presence or absence of bladder distension. A normal urine output is about 30 ml per hour, and a normal bladder should feel soft and empty after voiding. If the urine output is low or high, or if the bladder feels firm or full after voiding, the PN should report these findings to the primary healthcare provider for further evaluation and intervention.

Therefore, option B is the correct answer, while options A, C, and D are incorrect.

Option A is incorrect because catheterizing the client for residual urine volume is an invasive procedure that should only be done if indicated by the primary healthcare provider.

Option C is incorrect because evaluating for normal involution and massaging the fundus are related to uterine function, not urinary function.

Option D is incorrect because obtaining a specimen for urine culture and sensitivity is not necessary unless there are signs of infection, such as fever, dysuria, or foul-smelling urine.

The PN should palpate the rate and volume of the pulse, measure body weight at the same time daily, and observe the color and amount of urine when assessing a client for signs and symptoms of fluid volume excess. These actions can help detect changes in the cardiovascular, renal, and fluid balance systems that may indicate fluid overload, such as tachycardia, bounding pulse, weight gain, edema, oliguria, or dark urine.

The other options are not correct because:

b. Checking fingernails for the presence of clubbing is not relevant for assessing fluid volume excess, as clubbing is a sign of chronic hypoxia or lung disease that causes enlargement of the fingertips and nails.

e. Comparing muscle strength of both arms is not relevant for assessing fluid volume excess, as muscle weakness is not a specific sign of fluid overload, but may be caused by various factors such as electrolyte imbalance, nerve damage, or fatigue.
