A nurse is preparing to administer heparin at 1,000 units/hr via continuous IV infusion to a client who had a coronary artery bypass graft. Available is heparin 25,000 units in dextrose 5% in water in 250 mL. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["10"]
ML
The formula to calculate the IV flow rate is:
mL/hr =
(Desired dose (units/hr)×Total volume (mL))/ Available dose
Substituting the given values:
(1,000×250)/25000
= 250,000/25,000
= 10ml/hr

Correct Answer is {"dropdown-group-1":"E","dropdown-group-2":"E"}
Explanation
The nurse should prepare to administer naloxone and oxygen by face mask 10 L/min.
Rationale:
- Naloxone is used to reverse opioid-induced respiratory depression, which is a potential risk during moderate sedation.
- Oxygen by face mask 10 L/min is necessary to maintain adequate oxygenation during and after sedation, as respiratory depression can occur.
- Acetaminophen is not used for immediate management of sedation-related complications.
- An additional dose of fentanyl or propofol would deepen sedation, not manage its complications.
- Propranolol is a beta-blocker that is not indicated in this situation.
Correct Answer is C
Explanation
A. A bologna sandwich on rye bread. This is incorrect because rye bread contains gluten, which must be avoided in a celiac disease diet.
B. Whole wheat pasta with shrimp. This is incorrect because whole wheat pasta contains gluten, making it unsuitable for a child with celiac disease.
C. A corn tortilla with black beans. This is correct because corn tortillas are naturally gluten-free, and black beans provide a nutritious, safe option for a child with celiac disease.
D. Low sodium vegetable soup with barley. This is incorrect because barley contains gluten, making it inappropriate for a celiac-friendly diet.
