Q

Hemoglobin A1C

A

a diagnostic test used to measure the percentage of glycosylated hemoglobin in the blood.

  • A normal hemoglobin A1C is 4%-6% in clients without diabetes
  • the goal is to keep the level <7% in clients with diabetes. - The A1C test measures blood glucose control over a period of 2-3 months; higher measurements indicate higher glycemic levels.

Q

Normal weight gain during pregnancy

A
  • A 1.1-4.4 lb (0.5-2.0 kg) weight gain in the first trimester is normal and indicates a good, healthy diet and a growing fetus.
  • After the first trimester, a weight gain of 1 lb (0.5 kg) per week is often expected. This weight gain varies by pre-pregnancy BMI.

25
normal platelet count
150,000-400,000/mm3
26
therapeutic PTT range is
25-35 seconds | normal during anticoagulation therapy is 1.5-2 times the normal reference of 25-35
27
A normal prothrombin time is
11-16 seconds
28
How to calculate mean arterial pressure/what is normal
(Systolic Blood Pressure + (Diastolic Blood Pressure × 2)) all divided by 3 MAP = (2 x DBP + SBP) / 3 A normal MAP is between 70-105 mm Hg. If the MAP falls below <60 mm Hg, vital organs may be underperfused and can become ischemic
29
Normal PaCO2 is
35-45 mm Hg
30
Normal PaO2
>80 mm Hg
31
normal range for the number of wet diapers
- is 6-10/day, or approximately 1 every 4 hours. - Infants create 2 mL/kg/hr normal urine output. The number of wet diapers/day is one of the best indications of adequate fluid intake (hydration).
32
normal BMI
18.5-24.9 kg/m2
33
The Parkland formula
(4 mL * weight in kg * percentage of body burned) calculates the 24-hour fluid resuscitation requirements in a burn client - half is given during the first 8 hours.
34
the goal during anticoagulation therapy is a PTT 1.5-2 times the normal reference range of
25-35 seconds
35
Normal newborn head circumference is
12.5-14.5 in (32-37 cm)
36
The rule of nines
is an estimated percentage of total body surface area burned in an adult. - The head is 9%, anterior torso 18%, posterior torso 18%, each arm 9%, each leg 18%, and groin 1%. - The rule of nines is often used at the initial evaluation and should be recalculated within the first 72 hours.
37
normal CVP (central venous pressure) is
2-8 mm Hg is a measurement of right ventricular preload (volume within the ventricle at the end of diastole) and reflects fluid volume problems. An elevated CVP can indicate right ventricular failure or fluid volume overload.
38
normal SVR (systemic vascular resistance) is
800-1200 dynes/sec/cm-5
39
BNP
normal <100 BNP is a peptide that causes natriuresis. B-type natriuretic peptides are made, stored, and released primarily by the ventricles. They are produced in response to stretching of the ventricles due to the increased blood volume and higher levels of extracellular fluid (fluid overload) that accompany heart failure. Elevation of BNP >100 pg/mL helps to distinguish cardiac from respiratory causes of dyspnea. - elevation is normal in pts with heart failure
40
Normal pupil diameter.
3-5 mm in diameter
41
target range for blood sugar when getting TPN
140-180 mg/dL
42
normal CD4+ cell count
500-1,200/mm3 Low CD4 counts are defined as <750/mm3 for infants 12 months or younger, <500/mm3 for children between age 1-5 years, and <200/mm3 for children age >5 years and adults
43
Normal eosinophil count is
Normal eosinophil count is 1%-2%. Elevated eosinophils are seen in allergy. In a client with an asthma exacerbation, a high eosinophil count would indicate an allergic trigger for the asthmatic response. The nurse should explore the client's allergy history and ways to reduce the allergic exposure that may be contributing to the exacerbation.
44
Normal reticulocyte count is
Normal reticulocyte count is 0.5%-2.0%. Reticulocytes are immature red blood cells Levels are elevated in hemolytic anemia or hemorrhage when the marrow is attempting to compensate for lost blood.
45
Normal neutrophils are
Normal neutrophils are 55%-70%. | Elevated neutrophils indicate infection
46
normal urine output
30 ml/hr | 0.5-1.0 mL/kg/hr
47
normal Glasgow coma scale
15
48
HCO3
22-26 mEq/L
49
Lithium levels
Lithium has a very narrow therapeutic index (0.6-1.2 mEq/L) | levels >1.5 mEq/L (1.5 mmol/L) are considered toxic
50
ALT
10-40 U/L
51
Normal urine specific gravity is
1.003-1.030. | Elevated specific gravity can indicate concentrated urine and be a sign of dehydration
52
vancomycin trough normal level
10-20 mg/L
53
absolute neutrophil count
2200-7700/mm3
54
normal sodium
135-145 mEq/L
55
normal hemoglobin
11.7-15.5 g/dL
56
normal phosphorus levels
2.4–4.4 mg/dL
57
leukocytosis =
elevated WBC >10,0000
58
Naegele's rule
can be used to quickly determine an EDB early in the pregnancy. This calculation uses the date of the first day of the last normal menstrual period (LMP) for determination of EDB. EDB = (LMP minus 3 months) + 7 days
59
A neonate's resting pulse is
110-160/min. Crying or vigorous kicking can cause a temporary rise. Vital signs are concerning if they rise when a client is at rest
60
normal ph level
7.35-7.45
61
LDL
<100 mg/dL
62
normal phosphorous
2.3-4.4 mg/dL
