How to assess a patient's cardiovascular status?
Assess the patient's cardiovascular status by checking pulse and blood pressure.
Why do you need to monitor blood pressure and sodium levels?
Blood pressure, lung sounds, and serum sodium levels must be monitored frequently because of the risk for excess intravascular volume with hypertonic solutions. You are caring for a patient admitted with diabetes, malnutrition, and a massive GI bleed.
What is potassium diuretic?
A potassium-sparing diuretic is contraindicated in a patient with hyperkalemia. Management of patients with hyperkalemia may include limiting foods high in potassium, administering IV insulin and glucose, administering IV calcium gluconate, changing to potassium-wasting diuretics (e.g., furosemide [Lasix]), hemodialysis, administering sodium polystyrene sulfonate (Kayexalate), and IV fluid administration.
What happens when the cap off the central line is off?
The cap off the central line could allow entry of air into the circulation, causing an air embolus. Catheter occlusion, precipitate build up in lumen manifest with sluggish infusions. Insertion site trauma manifests with edema near the insertion site and dysrhythmias.
How many ml syringes to use for catheter flush?
Use a 5-mL syringe to flush the catheter between medications and after use.

Measuring weight is the most reliable means of detecting changes in fluid balance. Weight loss would indicate the dehydration is worsening, whereas weight gain would indicate restoration of fluid volume.
How much fluid is needed to replace insensible fluid loss?
Daily fluid intake and output is usually 2000 to 3000 mL. This is sufficient to meet the needs of the body and replace both sensible and insensible fluid losses. These would include urine output and fluids lost through the respiratory system, skin, and GI tract.
What happens when calcium levels drop?
When blood levels of calcium decline, secretion of parathyroid hormone increases. Calcium moves from bone to blood, intestinal absorption of calcium increases, renal excretion of c ... (more)
When are serum calcium levels monitored?
When bisphosphonates are administered, serum calcium levels are monitored before, during, and after therapy.
What vitamins help bone growth?

Can hypercalcemia cause kidney damage?
Correct response: Hypercalcemia can lead to calcium deposits that damage the kidneys.
Is calcium chloride IV or IV?
Calcium chloride is an IV preparation and calcitriol is a vitamin D preparation given orally. All others are appropriate examples of calcium taken orally.
How much fluid is needed to replace insensible fluid loss?
Daily fluid intake and output is usually 2000 to 3000 mL. This is sufficient to meet the needs of the body and replace both sensible and insensible fluid losses. These would include urine output and fluids lost through the respiratory system, skin, and GI tract.
Why are loop diuretics contraindicated?
Loop diuretics are contraindicated during episodes of hypokalemia because these medications cause the kidneys to excrete sodium and potassium. Thus administration of this type of medication at this time would worsen the hypokalemia, putting the patient at risk for dysrhythmias. The prescribing physician should be consulted for potassium replacement therapy, and the drug should be withheld until the potassium has returned to normal range.
Why is my kidney excreting potassium and sodium?
The patient may be excreting extra sodium and retaining potassium because of malnutrition.
Can hyperkalemia be caused by diabetes?
Hyperkalemia may result from hyperglycemia, renal insufficiency, and/or cell death. Diabetes mellitus, along with the stress of hospitalization and illness, can lead to hyperglycemia. Renal insufficiency is a complication of diabetes. Malnutrition does not cause sodium excretion accompanied by potassium retention.
Does calcium have an inverse relationship with phosphorus?
Calcium has an inverse relationship with phosphorus in the body. When phosphorus levels fall, calcium ris es, and vice versa. Since hypercalcemia rarely occurs as a result of calcium intake, the patient's phosphorus falling to 2.1 mg/dL (normal 2.4-4.4 mg/dL) may be a result of the phosphate-binding effect of calcium carbonate.
Does malnutrition cause potassium retention?
Malnutrition does not cause sodium excretion accompanied by potassium retention. Thus it is not a contributing factor to this patient's potassium level. Stored hemolyzed blood can cause hyperkalemia when large amounts are transfused rapidly. The patient with a massive GI bleed would have an NG tube and not be eating.
What is the most important investigation for hypocalcaemia?
If the cause of hypocalcaemia is not clinically obvious the most important investigation is to measure serum parathyroid hormone. A standard biochemical profile, a parathyroid hormone measurement, and the clinical history will usually provide the likely cause of hypocalcaemia. Figure 55shows an algorithm for investigating hypocalcaemia.
What hormones are responsible for calcium absorption?
The concentration of calcium in the serum (normal range 2.10-2.60 mmol/l)is regulated by the action of parathyroid hormone and vitamin D on the kidneys, bones, and gastrointestinal tract (fig 1)1).. Parathyroid hormone stimulates calcium resorption in the kidney and calcium release from bone. It also stimulates renal production of 1,25-dihydroxyvitamin D (calcitriol) from 25-hydroxyvitamin D. 1,25-Dihydroxyvitamin D is the most active form of vitamin D, and it acts on the gastrointestinal tract to increase calcium absorption. Vitamin D is obtained mainly through synthesis in the skin, with a small contribution from the diet. Skin synthesis requires exposure to ultraviolet light and is reduced by skin pigmentation.
What is the best medication for parathyroid deficiency?
Patients with parathyroid hormone deficiency need calcitriol or alfacalcidol rather than conventional doses of colecalciferol or ergocalciferol
What are the symptoms of hypocalcaemia?
Thus, classic symptoms of hypocalcaemia are neuromuscular excitability in the form of muscle twitching, spasms, tingling, and numbness. Carpopedal spasm is characteristic but in severe cases can progress to tetany, seizures, and cardiac dysrhythmias. In patients without overt signs, underlying neuromuscular excitability can become evident with provocation—tapping the parotid gland over the facial nerve can induce facial muscle spasm (Chvostek’s sign; fig 3)3).. However, 10% of normal people have a positive Chvostek’s sign. Conversely, a small study of patients with hypoparathyroidism and biochemically confirmed hypocalcaemia found that 29% were negative for Chvostek’s sign, which makes this test a poor discriminator.10
What hormones interact with calcium?
Fig 1Regulation of serum calcium. Parathyroid hormone and vitamin D normally interact to protect against hypocalcaemia. Problems at any level can lead to low serum calcium, but the most common problems are vitamin D deficiency and hypoparathyroidism
Why do bisphosphonates cause hypocalcaemia?
Severe hypocalcaemia has been reported in patients with pre-existing vitamin D deficiency who receive intravenous bisphosphonates because these compounds block bone resorption.9Table 11outlines common and less common causes of hypocalcaemia.
Is hypocalcaemia a genetic disorder?
Hypocalcaemia occurs in patients with impaired function of the parathyroid glands. This is most common after thyroid or parathyroid surgery, but it can be idiopathic—mostly in young adults and less often as part of a genetic syndrome, such as autoimmune polyglandular syndrome type 1.7Reduced concentrations of parathyroid hormone lead to excessive renal calcium loss and reduced intestinal absorption of calcium secondary to decreased production of 1,25-dihydroxyvitamin D. Occasionally, tissue resistance to parathyroid hormone can produce a biochemical pattern similar to hypoparathyroidism, even though concentrations of the hormone are high. Such “pseudohypoparathyroidism” is caused by failure of parathyroid hormone to activate its signalling pathways.8Pseudohypoparathyroidism is a genetically heterogeneous condition, with some patients having skeletal abnormalities (Albright’s hereditary osteodystrophy; fig 2)2),, that can occur in other family members independent of any abnormality of serum calcium. The presence of these features and normal calcium biochemistry is termed pseudopseudohypoparathyroidism.
