What is an individual’s genetic makeup known as?

Choice A rationale:

Urine output (UO) does not completely stop during the oliguric phase of acute renal failure. While it is significantly reduced, some urine production still occurs. Complete cessation of urine output is known as anuria, which is a more severe condition and a medical emergency.

Anuria may occur in the most severe cases of acute renal failure, but it is not the defining characteristic of the oliguric phase.

It's crucial to distinguish between oliguria and anuria, as their management approaches differ significantly.

Choice B rationale:

During the oliguric phase of acute renal failure, urine output (UO) is less than 400 mL/24 hours. This is the defining characteristic of this phase.

The decrease in urine output is due to damage to the kidneys' filtering units, known as nephrons. As a result, the kidneys are unable to filter waste products and excess fluids effectively from the blood, leading to their accumulation in the body.

This reduced urine output can lead to various complications, including fluid overload, electrolyte imbalances, and a buildup of waste products in the blood (uremia).

Choice C rationale:

Urine output (UO) is always measured during the oliguric phase of acute renal failure. It is a vital clinical indicator to monitor the severity of kidney dysfunction and guide treatment decisions.

Accurate measurement of urine output is essential for assessing fluid balance, kidney function, and the effectiveness of treatment interventions.

Choice D rationale:

Urine output (UO) is not greater than 500 mL/24 hours during the oliguric phase of acute renal failure. A urine output greater than 500 mL/24 hours would indicate a non-oliguric phase of acute renal failure or a potential recovery phase.

Rationale for Choice A:

Administering oxygen via a mask or nasal cannula is the most appropriate nursing intervention in this situation. Here's a detailed explanation:

1. Addresses Hypoxia: The client's symptoms of lightheadedness, dizziness, and tingling fingers strongly suggest hyperventilation, which can lead to hypoxemia (low blood oxygen levels). Administering oxygen directly increases the concentration of oxygen in the client's bloodstream, rapidly addressing the hypoxia and its associated symptoms.
2. Promotes Calmness: Oxygen therapy can also have a calming effect, which can help to slow the client's breathing rate and further improve oxygenation. This is crucial during the transition phase of labor, as anxiety and stress can exacerbate hyperventilation.
3. Supports Fetal Oxygenation: Ensuring adequate maternal oxygenation is essential for fetal well-being. By providing oxygen to the mother, the nurse is also indirectly supporting the oxygen supply to the fetus.

Rationale for Choice B:

Telling the client to breathe at a normal rate is not an effective intervention for hyperventilation. It's often challenging for a client experiencing hyperventilation to control their breathing rate on command. This approach can also increase anxiety, potentially worsening the hyperventilation.

Rationale for Choice C:

While notifying the physician is important to keep them informed of the client's status, it's not the immediate priority in this situation. The nurse can independently initiate oxygen therapy to address the client's hypoxia and improve her condition. The physician can then be consulted for further guidance or interventions if needed.

Rationale for Choice D:

Instructing the client to breathe into her cupped hands is a technique that can sometimes help to slow breathing and increase carbon dioxide levels. However, it's not as effective as administering oxygen in addressing the underlying hypoxia and may not provide sufficient relief for the client's symptoms.
