Q

How does Antidiuretic hormone (ADH) work to maintain fluid balance and homeostasis?

A

by increasing the permeability of the kidney’s collecting ducts and distal convoluted tubules to water. This allows more water to be reabsorbed back into the bloodstream, reducing urine volume and concentrating the urine.

Q

How does Atrial Natriuretic peptide (ANP) work to maintain fluid balance and homeostasis?

A

helps maintain fluid balance by promoting sodium and water excretion by the kidneys. It acts by increasing GFR and inhibiting the reabsorption of sodium in the renal tubules, which leads to increased urine production and reduced blood volume.

Q

Infants’ fluid balance

A

Infants have a higher percentage of body water compared to adults, making them more susceptible to fluid imbalances. Their higher metabolic rate leads to increased water turnover and greater fluid needs.

Q

How does acute illness affect fluid balance?

A

The body’s response to acute infection often includes fever, which increases insensible water loss through sweat and respiration.

38
Q

How does chronic illness affect fluid balance?

A

it can impair the kidneys’ ability to excrete waste and maintain electrolyte levels. This can lead to fluid retention.

39
Q

How does environmental factors affect fluid balance?

A

high temperatures and humidity can increase sweating, leading to reduced urine output as body conserves water. Conversely, cold environments can trigger diuresis, resulting in increased urine production.

40
Q

How can diet affect fluid balance?

A

High sodium intake can lead to fluid retention, deceasing urine output. While diuretic foods and beverages like caffeine and alcohol can increase urine production.

41
Q

How can lifestyle affect fluid balance?

A

High levels of physical activity can increase fluid loss through sweat, leading to reduced urine output if hydration is not adequately maintained. Sedentary lifestyles can contribute to lower fluid intake and potentially result in concentrated urine and reduced kidney function.

42
Q

How can medication affect fluid balance?

A

Diuretics increase urine production by promoting the excretion of sodium and water

43
Q

Describe the reason the registered nurse would promote maintenance of an adequate fluid intake.

A

Essential for maintaining proper hydration,e ensuring optimal kidney function, and preventing urinary tract infections. Adequate fluid intake helps dilute urine

44
Q

Describe the reason the registered nurse would promote maintenance of normal bowel functioning.

A

crucial for preventing constipation and ensuring effective waste elimination. Regular bowel movements help prevent discomfort and complications like haemorrhoids and bowel obstruction.

45
Q

Describe the reason the registered nurse would educate the client about pelvic floor exercises.

A

Important for strengthening the muscles that support the bladder and bowel, which can improve control over urinary and bowel functions.

46
Q

Why does the nurse need to assess skin & mucosal membranes?

A

helps evaluate hydration status and identify signs of dehydration or fluid imbalance. Changes in skin turgor, colour, and mucosal dryness can indicate underlying issues requiring timely intervention

47
Q

Why do nurses need to assess weight changes?

A

to monitor for fluid retention or loss, which can indicate issues such as dehydration, edema, or chronic conditions. Significant or sudden weight fluctuations can help identify and address underlying health problems or the effectiveness of ongoing treatments.

48
Q

Why do nurses need to assess oral intake?

A

to ensure that the patient is receiving adequate hydration and nutrition. Monitoring fluid and food intake helps identify potential deficiencies, imbalances, or excesses, which can impact overall health and guide appropriate dietary or fluid adjustments.

49
Q

Why do nurses need to assess fluid output?

A

to evaluate the body’s ability to excrete waste and maintain fluid balance. Monitoring urine, stool, and other outputs helps identify potential issues such as dehydration, fluid retention, or renal problems, and guides appropriate interventions to address any imbalances.

50
Q

Explain the rationale the registered nurse would record all output and input of fluid.

A

to monitor a patient’s hydration status and detect any early signs of dehydration or overhydration., it helps in detecting complications from medical conditions and evaluating the effectiveness of treatments. What comes in should always come out

51
Q

List the information that would be recorded on a fluid balance chart

A

Patient information, fluid intake, fluid output, total. intake and output, balance and additional notes

52
Q

Explain why a fluid balance chart would be totalled over a 24 hour period.

A

to give a comprehensive overview of a patient’s fluid status, aiding in the identification of trends and imbalances. This timeframe allows for accurate assessment and informed decisions regarding hydration and treatment adjustments
