1.Doğum ve kadın sağlığı hemşireliği
Cevap: C · When she can brake hard without pain
Cevap neden bu
There is no fixed time. She can drive when she can brake suddenly, look over her shoulder and wear a seat belt comfortably. Many women need about 4 to 6 weeks, and insurance rules may apply.
Cevap
C · When she can brake hard without pain
2.Doğum ve kadın sağlığı hemşireliği
Cevap: D · It is abnormal and needs prompt review
Cevap neden bu
A score of 8 to 10 is normal, 6 is equivocal, and 4 or less is abnormal and suggests fetal hypoxia. At term, a low score usually leads to prompt review and consideration of birth.
Cevap
D · It is abnormal and needs prompt review
3.Doz hesapları
Cevap: D = 29,6 mg
Body-surface-area dosing: many cytotoxic and some paediatric doses are prescribed per square metre of body surface area: dose (mg) = dose per m² × BSA (m²). The Mosteller formula estimates BSA = √(height (cm) × weight (kg)/3600).
Doz
D = 20·1,48 = 29,6 mg
Cevap
D = 29,6 mg
4.Doz hesapları
Cevap: D = 197,5 mg
Body-surface-area dosing: many cytotoxic and some paediatric doses are prescribed per square metre of body surface area: dose (mg) = dose per m² × BSA (m²). The Mosteller formula estimates BSA = √(height (cm) × weight (kg)/3600).
Vücut yüzey alanı
BSA = √(131·35/3600) = √1,274 = 1,129 m²
Doz
D = 175·1,129 = 197,5 mg
Cevap
D = 197,5 mg
5.IV infüzyon hızları
Cevap: R = 25 gtt/min
Infusion rates: a pump is set in mL/h = volume/time in hours. A gravity drip is counted in drops per minute: gtt/min = volume (mL) × drop factor (gtt/mL)/time (min). The drop factor is printed on the tubing package: macrodrip sets deliver 10, 15 or 20 gtt/mL (blood sets often 10 gtt/mL in the US, 15 in the UK) and microdrip sets 60 gtt/mL. Always use the drop factor the question or package gives.
Dose-based infusions: concentration = amount of drug in the bag/bag volume. Pump rate (mL/h) = dose per hour/concentration, and dose per hour = mL/h × concentration. Convert per-minute doses to per-hour (× 60) and keep the mass units the same (1 g = 1000 mg, 1 mg = 1000 mcg).
