A nurse administers NPH insulin to a post-op patient (2 days post-appendectomy) at 8:00 am. At 2:00 pm, the patient is found guarding his right lower abdomen, extremely lethargic but conscious, diaphoretic, and slightly combative.
The patient’s vital signs are: T=99.1, HR=80, BP=109/62, RR=18, SPO2=97%. What should the nurse do first?
Assess the patient’s blood sugar using a bedside finger stick blood glucose test.
Administer the next dose of insulin STAT.
Administer Narcan (Naloxone) STAT.
Administer 2L O2 via nasal cannula.
The Correct Answer is A
Choice A rationale:
Hypoglycemia is a critical consideration: The patient's symptoms of lethargy, diaphoresis, and combativeness, along with recent insulin administration, raise a strong suspicion of hypoglycemia (low blood sugar). Hypoglycemia can quickly progress to coma and seizures if not promptly treated, making it a high priority to assess and address.
Bedside glucose testing is rapid and reliable: A bedside finger stick blood glucose test is a quick, non-invasive, and accurate way to determine the patient's blood sugar level. It provides immediate results, allowing for prompt intervention if hypoglycemia is confirmed.
Other assessments and interventions can follow: Once hypoglycemia is ruled out or confirmed, the nurse can proceed with other assessments and interventions as needed.
Choice B rationale:
Insulin administration without blood sugar confirmation is dangerous: Administering insulin without first checking the patient's blood sugar could worsen hypoglycemia if it is already present. This could lead to severe complications, including neurological damage or even death.
Insulin timing is not a priority: While the next dose of insulin may be due, its administration is not the most urgent priority in this situation. Addressing the patient's immediate symptoms and potential hypoglycemia takes precedence.
Choice C rationale:
Naloxone is not indicated for hypoglycemia: Naloxone is an opioid antagonist used to reverse opioid overdose. It has no effect on hypoglycemia and would not be appropriate in this case.
Choice D rationale:
Oxygen therapy may not address the underlying issue: While oxygen therapy can be beneficial for patients with respiratory distress, it does not address the potential hypoglycemia in this case. If the patient's lethargy and combativeness are due to low blood sugar, oxygen therapy alone would not be sufficient treatment.
Oxygen saturation is already within normal limits: The patient's oxygen saturation (SPO2) is 97%, indicating that their oxygenation is currently adequate. Oxygen therapy would not be indicated unless there were signs of hypoxia.

Correct Answer is A
Explanation
Choice A rationale:
Insulin is a protein-based hormone that is sensitive to heat and light. Exposure to high temperatures or direct sunlight can cause insulin to break down and become less effective.
Refrigeration helps to maintain the stability and potency of insulin. It is generally recommended to store unopened insulin vials in the refrigerator at a temperature between 36°F and 46°F (2°C and 8°C).
This temperature range helps to slow down the degradation process and ensure that the insulin remains effective until its expiration date.
Choice B rationale:
Insulin should never be frozen. Freezing can cause the insulin to crystallize and become unusable. Once insulin has been frozen, it cannot be thawed and used again.
Choice C rationale:
Opened vials of insulin do not need to be discarded immediately. They can be stored in the refrigerator for up to 28 days, depending on the type of insulin.
However, it is important to note the date that the vial was opened and to discard it after the recommended storage period.
Choice D rationale:
Insulin pens should be stored according to the manufacturer’s instructions. Some insulin pens can be stored at room temperature for a certain period of time, while others must be refrigerated.
It is important to read the instructions that come with the insulin pen to ensure that it is stored properly.
Correct Answer is C
Explanation
Choice A rationale:
Insulin resistance is a condition in which the body's cells become less responsive to insulin, requiring more insulin to maintain normal blood glucose levels.
It's primarily caused by factors such as obesity, physical inactivity, and genetic predisposition. Rotating injection sites does not directly address these underlying causes of insulin resistance.
It can help ensure consistent insulin absorption, but it's not the primary mechanism for preventing insulin resistance.
Choice B rationale:
Allergic reactions to insulin are rare but can occur.
They typically manifest as localized symptoms at the injection site, such as redness, swelling, itching, or pain.
In severe cases, systemic reactions like hives, difficulty breathing, or anaphylaxis can occur.
Rotating injection sites might reduce the risk of localized allergic reactions by preventing repeated exposure to insulin in the same area of skin.
However, it does not prevent systemic allergic reactions, which are immune-mediated and not dependent on the injection site.
Choice C rationale:
Lipodystrophy is a condition characterized by abnormal changes in fat distribution under the skin. It can occur as a complication of repeated insulin injections at the same site.
There are two main types of lipodystrophy:
Lipohypertrophy: This involves the accumulation of excess fatty tissue at injection sites, creating visible lumps or bumps. Lipoatrophy: This involves the loss of fatty tissue at injection sites, leading to depressions or indentations in the skin.
Both lipohypertrophy and lipoatrophy can interfere with insulin absorption, leading to unpredictable blood glucose control.
Rotating injection sites helps to prevent lipodystrophy by distributing insulin injections over a wider area of skin, reducing the likelihood of repeated trauma to the same tissue.
Choice D rationale:
Insulin shock, also known as hypoglycemia, is a condition that occurs when blood glucose levels drop too low.
It can be caused by several factors, including excessive insulin dosing, missed meals, or increased physical activity. Rotating injection sites does not directly affect the risk of insulin shock.
It's essential for individuals using insulin to monitor their blood glucose levels regularly, adjust insulin doses as needed, and follow a balanced diet and exercise plan to prevent hypoglycemia.
