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 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.
Correct Answer is C
Explanation
Choice A reason: The blood should not be infusing for 5 hours as transfusions of packed RBCs should be completed within 2 to 4 hours to minimize the risk of bacterial growth and transfusion reactions.
Choice B reason: Medications should not be administered through the same IV line as blood products due to the risk of reactions and interactions.
Choice C reason: The packed RBCs are indeed connected by Tubing to normal saline, which is used to keep the line open and prevent clotting.
Choice D reason: The drip chamber should not be filled completely with blood as it is necessary to monitor the drip rate and to ensure that air does not enter the line.
