A nurse caring for a client who has hypertension is asked about a prescription for propranolol. The nurse should inform the client that this medication is contraindicated in clients who have a history of which of the following conditions?
Asthma
Glaucoma
Depression
Migraines
The Correct Answer is A
Choice A reason: Propranolol is contraindicated in patients with asthma as it may cause bronchoconstriction, exacerbating respiratory difficulties.
Choice B reason: Glaucoma is not a contraindication for propranolol; in fact, betablockers can be used to treat glaucoma by reducing intraocular pressure.
Choice C reason: Depression is not a direct contraindication, but caution is advised as propranolol can sometimes worsen symptoms of depression.
Choice D reason: Propranolol is often used as a preventive treatment for migraines and is not contraindicated in patients with this condition.

Correct Answer is D
Explanation
Choice A reason: Humidifying the client's room can help maintain mucous membrane integrity and prevent respiratory infections, which is crucial for a client with a low WBC count.
Choice B reason: Replacing the water in flower vases daily can prevent the growth of bacteria, reducing the risk of infection for an immunocompromised client.
Choice C reason: Cleaning dentures in a denture cup is a standard infection control practice that helps maintain oral hygiene and prevent infections.
Choice D reason: Serving cooked fruit with meals reduces the risk of transmitting infections that can be associated with raw fruits, which is important for a client with neutropenia.
Correct Answer is C
Explanation
Choice A reason: Renal function is not typically reestablished during the oliguric phase of acute kidney injury; this phase is characterized by a significant reduction in urine output due to renal tubule damage.
Choice B reason: BUN and creatinine levels usually increase during the oliguric phase because the kidneys' ability to filter and excrete these waste products is compromised.
Choice C reason: The oliguric phase is defined by a urine output of less than 400 mL per 24 hours, which is a result of decreased kidney function and damage to the renal tubules.
Choice D reason: The GFR does not recover during the oliguric phase; instead, it is typically low due to reduced kidney function. Recovery of GFR occurs later in the recovery phase of acute kidney injury.
