NSG 303 LAB FINAL EXAM REVIEW
Your patient is on a heparin drip protocol for treatment of DVT. The most recent PTT
results determined that the patient will require a dose of 17 units/kg/hour of Heparin.
Your patient weighs 55 kg. The available concentration of Heparin is 25,000 units per
250 mL. How many units of heparin will the patient receive each hour? - Answers - 935
units/hr
The provider orders Phenobarbitol for your patient who has recently been diagnosed
with epilepsy. The recommended safe dose range for treatment is 10-12 mg/kg/day in
divided doses TID. You have Phenobarbitol 125mg/5mL available. What is the safe
maximum daily dose for a child who weighs 12 kg? - Answers - 144 mg/day
nasal cannula - Answers - - most used O2 device
FiO2
varies depending on flow of oxygen and pt's depth of breathing
- 1-2 L/min: 24-28% FiO2
- 3-4 L/min: 32-36% FiO2
- 5-6 L/min: 40-44% FiO2
simple oxygen mask - Answers - - Actual delivered O2 concentration varies with
breathing pattern
- Not suitable for clients with COPD because of potential for excessive oxygenation
- Should ideally be used with humidification
- <6 L/min can lead to CO2 buildup
FiO2
- typically 6-10 L/min: 40-60% FiO2
non-rebreather mask - Answers - - Delivers the highest O2 concentration possible
without mechanical ventilation
- One-way valve prevents room air or exhaled air from being trapped
- Use significant flow to keep O2 reservoir inflated
FiO2
- 10-15 L/min (enough to keep the bag 2/3 full): 80-95% FiO2
venturi mask - Answers - - Delivers O2 concentration accurate within 1%
- Frequently used with clients with COPD, but still use with caution
- Essential to adjust mask according to specifications to ensure accurate O2 delivery
- Interferes with talking and eating (may need nasal cannula order for meals)
FiO2
- 4-10 L/min: 24-50% FiO2
, face tent - Answers - - Alternative for patients who feel claustrophobic in aerosol mask
- Common in s/p nasal and oral surgery patients
- Soft mask for under the chin and loosely covers the mouth and nose
- Difficult to keep in place
- Convenient for humidification and oxygenation, but O2 concentration is not controlled
FiO2
- at least 10 L/min: 24-100% FiO2
manual resuscitation bag - Answers - - Provides high concentrations of O2
prior to suctioning, intubation, during respiratory or cardiac arrest
- Soft air-filled cushion around the mask to form airtight seal over patient's mouth &
nose
- Apex: (narrowest part) covers the nose
- Base: (broader portion) covers the mouth
- Self-inflating bag: firm, rubber like material to manually be compressed to deliver "a
breath" to the patient
FiO2
- When connected to O2, typically 10-15 L/min
Tracheostomy Mask/Collar - Answers - - Small mask that fits over the tracheostomy
site, with elastic band that fits around the patient's neck to hold it in place
- Requires continuous humidification
FiO2
- typically 10 L/min
- nebulizer to set appropriate FiO2 concentration
Oxygen tent & hood - Answers - Advantages:
- Option for children who will not leave a face mask or nasal cannula in place
- Gives the patient freedom to move in bed or crib while humidified oxygen is being
delivered
Disadvantages:
- Hard to keep closed due to contact with patients
- Difficult to maintain a consistent level of oxygen and deliver oxygen at a higher rate
than 30%-50%
- The oxygen hood consists of a disposable vinyl box that fits over the child's head.
- It provides warm humidified oxygen at a specific temperature.
- When using a hood, it is important to ensure that there is enough space between the
curve of the hood and the child's neck to allow carbon dioxide to escape.
FiO2
- oxygen hood: depends on the flow rate and size of the hood
