While changing the dressing of a client who is immobile, the nurse notices the boundary of the wound has increased. Given there is a positive methicillin-resistant Staphylococcus aureus (MRSA), which is the most important action for the nurse to take?

- 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 Herpes zoster (shingles) vaccination is recommended for adults aged 60 years and older, regardless of whether they have had shingles or chicken pox before. The vaccine can reduce the risk of developing shingles and its complications, such as postherpetic neuralgia.

The other options are not correct because:

a. The vaccine is useful even if the person has had a case of shingles before, as shingles can recur in some people. The vaccine can prevent or reduce the severity of future episodes.

c. The person needs to get this vaccination even if they have had chicken pox, as shingles is caused by the reactivation of the same virus that causes chicken pox (varicella-zoster virus). The vaccine can boost the immunity against the virus and prevent it from reactivating.

d. The vaccination does not minimize outbreaks of cold sores, as cold sores are caused by a different virus (herpes simplex virus). The vaccine has no effect on this virus or its symptoms.
