Q

Patient with acid-base imbalance. (Metabolic Acidosis)
What additional lab values should you check if a patient has (Metabolic-Acidosis)

A
  • Arterial blood gas results for metabolic acidosis are pH less than 7.35 and
    HCO3– less than 22 mEq/L. If compensated, then the PaCO2 is less than 35 mm Hg.
  • Metabolic acidosis is an acid-base imbalance caused by an increased accumulation of metabolic acids that rise in proportion to bicarbonate and result in decreased arterial pH.
  • treatment depends on the underlying cause.
  • Potassium levels

46

Hypokalemia (low potassium)

47
Q

T or F:
if a patient has an NG tube and it is connected to suction, it puts the patient at risk for metabolic alkalosis

True

48
Q

A

dehydration

49
Q

If BP is low, are you going to give 0.45 Normal Saline?

A
  • No we would give pt NS (0.9% NS)
50
Q

Know the different IV fluids and what they are used for when treating a patient.

A

Isotonic Fluids are go-to IV fluids for rehydration and maintenance fluids
o Dehydration
o nausea/vomiting/diarrhea
o Bolus or maintenance
o AKI
o Hyponatremia
o Hypotension
o Sepsis
o burns

Hypotonic fluids have lower concentration of solutes than blood plasm, causing intracellular shift of fluids, leading to cellular swelling
o ½ NS (0.45% NS) (Maintenance fluids, DKA)
o D5W (Mixed with meds, hypernatremia, overly corrected hyponatremia)

Hypertonic Fluids (0.3%) have higher concentration of solutes than blood plasma, causing extracellular shift of fluid leaking to cellular dehydration and “shrinking”
o Severe hyponatremia
o Increased ICP

51
Q

What are the characteristics of Metabolic Alkalosis?

A
  • May be caused by losing too much acid from the body, or by having to much bi carbonate
  • Muscle twitching and cramps
  • Tetany
  • Dizziness
  • Lethargy
  • Weakness
  • Disoriented
  • Coma
  • Nausea / vomiting
  • Depressed respirations
52
Q

What is the function of Aldosterone? If a patient is taking a medication that inhibits Aldosterone secretion and release, what potential complication can it cause? Hint: (What Electrolyte will it affect)

A
  • Aldosterone promotes the retention of sodium and water in the distal nephrons of the kidney, restoring blood volume.
  • Aldosterone is a naturally occurring hormone of the mineralocorticoid type that increases the reabsorption of water and sodium in the kidney at the same time that it promotes excretion of potassium.
  • Any drug or condition that disrupts aldosterone secretion or release increases the clients risk for excessive water loss and increased potassium reabsorption. The client would not be at risk for over hydration or sodium in balance
  • Complication is hyperkalemia / affects potassium
    o Affects potassium as in to much potassium since it is blocking sodium
53
Q

The Potassium level is high what abnormalities will show up on the EKG?

A
  • In potassium levels of greater than 7.5 mEq/L, there is a disappearance of the P wave with the development of junctional rhythms. As the potassium level exceeds 9.0 mEq/L, the QRS complex continues to widen
54
Q

Your patient has Hypocalcemia. What clinical manifestations will be present with Hypocalcemia?

A
  • May have no symptoms, focal numbness, muscle spasm, paresthesias, twitching, tremors and tetany, dysphagia
55
Q

difficulty/pain/discomfort with urination that may indicate obstruction, infection, UTI, or cystitis

A

dysuria

56
Q

presence of blood in the urine

A

hematuria

57
Q

What does Urinary Retention mean?

A
  • occur due to complications from anesthesia, opioids, and immobility.
    o Anesthesia depresses the nervous system, which can affect the nervous system’s control of micturition.
  • can result in a decreased sensation of a full bladder and urinary retention.
    o Opioids -may interfere with the patient’s ability to fully empty the bladder.
    o Immobility and bedrest impact the ability to fully relax the perineal structures to allow voiding and complete emptying of the bladder.
58
Q

Why do percuss the Costovertebral angle?

A
  • Percuss to assess for pain or tenderness-if pain/ tenderness is reported, suggestive of kidney inflammation or infection.
  • location of the kidneys can be estimated by the costovertebral angle
59
Q

How do you collect a Clean Catch Urine Specimen?(

A
  • Wash hands.
  • Remove cap from sterile specimen container, ensuring not to touch the inside of the lid or container.
  • Males: Use enclosed towelette(s) to wipe the head of the penis.
  • Females: Spread the labia with one hand and use the other hand to wipe from front to back with the enclosed towelette(s).
  • Begin urinating a small amount into the toilet. Without stopping the flow of urine, place the cup into the stream of urine and collect enough urine to fill the cup. Finish urinating into the toilet.
  • Securely attach the cap onto the sterile container, ensuring not to touch the inside of the lid or container.
60
Q

A
  • pink tinged urine
    Gross bleeding and/or clots in the urine are not normal and should be reported to the healthcare provider
61
Q

What are some age related changes in the Renal System? SATA
