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 B
Explanation
Choice A rationale:
Requesting an order for morphine sulfate IV 2 mg over 1-5 minutes would not be appropriate at this time for several reasons: The patient has already received a dose of 4 mg 15 minutes ago, and it has not been effective in relieving the chest pain.
The patient is showing signs of increased respiratory effort, which could be a sign of respiratory depression. Administering an additional dose of morphine could worsen the respiratory depression.
The patient's heart rate is 82 beats per minute, which is within the normal range.
The patient's blood pressure is 135/88 mm Hg, which is also within the normal range.
Choice C rationale:
Administering naloxone (Narcan) to counteract respiratory depression would not be appropriate at this time because the patient is not showing signs of severe respiratory depression. Naloxone is a medication that is used to reverse the effects of opioid overdose. It is typically only used in situations where the patient is experiencing life-threatening respiratory depression.
Choice D rationale:
Administering morphine sulfate IV 4 mg over 1-5 minutes would not be appropriate for the reasons listed above. It could worsen the patient's respiratory depression and potentially lead to other complications.
Choice B is the best answer because it is the most conservative and safest option. By withholding the next dose of morphine and informing the provider about the patient's symptoms, the nurse can ensure that the patient receives the appropriate care and that any potential complications are avoided.
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.
