A patient has been treated for lung cancer for 3 years. Over the past few months, the patient has noticed that the opioid analgesic is not helping as much as it had previously and more medication is needed for the same pain relief. The nurse is aware that this patient is experiencing which of these?

Opioid abstinence syndrome

Opioid tolerance

Opioid toxicity

Opioid addiction

Answer and Explanation

The Correct Answer is B

Opioid tolerance occurs when the body becomes less responsive to the effects of opioids over time. This means that higher doses of the medication are needed to achieve the same level of pain relief that was previously achieved with lower doses. Opioid tolerance is a common phenomenon in long-term opioid therapy and can occur in patients who have been using opioids for an extended period.

Opioid abstinence syndrome, also known as opioid withdrawal, refers to the set of symptoms that occur when a person abruptly stops or reduces their use of opioids after developing physical dependence.

Opioid toxicity refers to the harmful effects that occur when an individual takes an excessive dose of opioids, leading to potentially life-threatening complications. It is characterized by symptoms such as respiratory depression, sedation, pinpoint pupils, and decreased level of consciousness.

Opioid addiction is a complex condition characterized by compulsive drug-seeking behavior, loss of control over opioid use, and continued use despite negative consequences.

Correct Answer is D

Explanation

Pain and coldness in the fingers following AVG placement can indicate impaired blood flow or compromised circulation to the hand. This may be due to complications such as thrombosis (clot formation), graft malfunction, or decreased arterial perfusion. These symptoms should be taken seriously and promptly communicated to the healthcare provider.
The healthcare provider needs to evaluate the patient's symptoms, assess the AVG, and determine the appropriate course of action. Prompt intervention can help prevent further complications and ensure adequate blood flow to the fingers.

Correct Answer is ["1.4"]

Explanation

We know that 7,000 units is equivalent to 5,000 units per ml. So, we can set up the proportion:

7,000 units / 5,000 units per ml = x ml / 1 ml x = 7,000 / 5,000

x = 1.4

Therefore, the nurse should administer 1.4 milliliters (ml) of heparin.
