In the diuretic phase of renal failure, which of the following happens?
Electrolytes improve.
Urine output (UO) does not change.
Urine output (UO) increases.
Oxygenation worsens.
The Correct Answer is C
Choice A rationale:
Electrolytes do not consistently improve during the diuretic phase of renal failure. While urine output increases, the kidneys' ability to regulate electrolytes may still be impaired. Electrolyte imbalances, such as hyperkalemia, hyponatremia, and hyperphosphatemia, can persist or even worsen during this phase.
Close monitoring of electrolytes is crucial to guide appropriate interventions, such as electrolyte replacement or restriction.
Choice B rationale:
Urine output (UO) does not remain unchanged during the diuretic phase. It is a defining characteristic of this phase that urine output increases, often significantly. This increase in urine output is a result of the recovering kidney tubules' ability to excrete fluid and waste products.
Choice C rationale:
Urine output (UO) increases in the diuretic phase of renal failure. This is a key feature that distinguishes this phase from the oliguric phase, which is characterized by decreased urine output. The increase in urine output is typically a sign of kidney function recovery. However, it is important to note that the increase in urine output does not necessarily mean that kidney function has fully recovered.
Choice D rationale:
Oxygenation does not typically worsen during the diuretic phase of renal failure. In fact, oxygenation may improve as fluid overload is resolved and pulmonary edema decreases. However, patients with underlying respiratory conditions or those who experience rapid fluid shifts may still require respiratory support.

Correct Answer is D
Explanation
Choice A rationale:
Fetal lung maturity is not assessed through chorionic villus sampling (CVS). It's primarily evaluated through amniocentesis, a different prenatal diagnostic procedure that involves sampling amniotic fluid.
CVS focuses on placental tissue, not lung development.
It's essential for clients to understand the specific purposes of each prenatal test to make informed decisions and have accurate expectations.
Choice B rationale:
While a non-stress test (NST) might be recommended after CVS in some cases, it's not a routine part of the procedure.
The decision to conduct an NST is based on individual risk factors and assessment by healthcare providers.
It's essential for clients to understand the potential need for additional testing but not assume it's always required.
Choice C rationale:
CVS is considered an invasive procedure, as it involves entering the uterus to collect placental tissue.
Non-invasive prenatal testing (NIPT) methods, which analyze fetal DNA in maternal blood, are available for screening purposes.
It's crucial for clients to differentiate between invasive and non-invasive prenatal testing options to make informed choices based on their preferences and risk factors.
Choice D rationale:
This statement accurately reflects the primary purpose of CVS.
It's a diagnostic procedure that can detect various genetic abnormalities, such as Down syndrome, cystic fibrosis, and TaySachs disease, during the first trimester of pregnancy.
Understanding the ability to detect genetic abnormalities early in pregnancy allows clients to make informed decisions about their pregnancy management and prepare for potential outcomes.
Correct Answer is C
Explanation
Choice A rationale:
Attaching the IV line to the distal port is not a safe practice for oxytocin administration. This is because oxytocin is a high-alert medication that can have serious adverse effects if administered incorrectly. Attaching the IV line to the distal port increases the risk of the medication being infused too quickly, which can lead to uterine hyperstimulation, fetal distress, or even uterine rupture. The safest practice is to attach the IV line to the proximal port, which is closer to the patient's body and allows for slower infusion rates.
Choice B rationale:
Customizing the concentration of oxytocin is not a recommended practice. Oxytocin is available in a premixed solution of 10 units/mL, and this concentration should not be altered. Altering the concentration can lead to dosing errors and increase the risk of adverse effects.
Choice D rationale:
Titrating oxytocin to gravity is not a safe practice. Oxytocin should be administered using an infusion pump that can accurately control the infusion rate. Infusion pumps are necessary to ensure that the medication is administered at the correct dose and rate. Gravity-based infusions are less accurate and can lead to over- or under-infusion of the medication.
Choice C rationale:
Two RN verification is a safe practice for oxytocin administration. This practice involves having two registered nurses independently verify the medication, dose, and infusion rate before administration. This helps to prevent errors and ensure that the medication is administered safely.
