A client who has a blood glucose level of 800 mg/dL is to receive insulin intravenously. Which form of insulin is safe for intravenous administration?
Insulin aspart (Novo Log).
Insulin glargine (Lantus).
Insulin lispro (Humalog).
Insulin regular (Humulin-R).
The Correct Answer is D
Insulin regular (Humulin-R) is the only form of insulin that is safe for intravenous administration. This is because it is a short-acting insulin that has a rapid onset and peak time, and does not contain any additives or suspensions that could interfere with the infusion.
Choice A is wrong because insulin aspart (Novo Log) is a rapid-acting insulin that is usually taken right before a meal. It is not suitable for intravenous use because it has a different amino acid sequence than human insulin.
Choice B is wrong because insulin glargine (Lantus) is a long-acting insulin that covers insulin needs for about a full day. It is not suitable for intravenous use because it forms micro-precipitates under the skin that release insulin slowly and steadily.
Choice C is wrong because insulin lispro (Humalog) is a rapid-acting insulin that is usually taken right before a meal. It is not suitable for intravenous use because it has a different amino acid sequence than human insulin.

Correct Answer is D
Explanation
temperature 101.8° F(38.8° C), BP 100/60 mm Hg, pulse 98/min, RR 28/min. This set of vital signs indicates that the client may have an infection or sepsis, which are potential complications of an open cholecystectomy. The client has a fever, tachycardia, tachypnea, and hypotension, which are signs of systemic inflammatory response syndrome (SIRS).
Choice A is wrong because it shows mild hypothermia, hypotension, and tachycardia, which could be due to dehydration or blood loss, but not necessarily infection.
Choice B is wrong because it shows a slight fever, normal blood pressure, and bradycardia, which could be due to pain or medication, but not infection.
Choice C is wrong because it shows a low-grade fever, normal blood pressure and pulse, and mild tachypnea, which could be due to inflammation or dehydration, but not infection.
Correct Answer is ["A","B","C","D"]
Explanation
A. Administer oxygen. This is the first priority because oxygen can help prevent further sickling of red blood cells and improve tissue perfusion.
B. Start IV fluids. This is the second priority because hydration can reduce blood viscosity and prevent vaso-occlusion.
C. Administer pain medication. This is the third priority because pain is a common and distressing symptom of sickle cell crisis and should be treated with opioids around the clock.
D. Draw lab work. This is the last priority because lab work can help monitor the severity of the crisis and the need for blood transfusions, but it does not directly relieve the patient’s symptoms or prevent complications.
