A nurse is caring for a patient who is postoperative and receiving fentanyl via patient-controlled analgesia. The patient has a prescription for naloxone.
What is the purpose of naloxone?
To suppress respiratory secretions
To block the effects of opioids on the central nervous system
To treat nausea
To treat urinary retention
The Correct Answer is B
Choice A rationale:
Naloxone does not have any direct effect on respiratory secretions. It works by binding to opioid receptors in the brain and reversing the effects of opioids, such as respiratory depression.
While opioids can cause a decrease in respiratory secretions, this is not the primary reason for administering naloxone.
It is important to note that naloxone can actually worsen respiratory secretions in some patients, particularly those with chronic obstructive pulmonary disease (COPD) or other respiratory conditions.
Choice B rationale:
Naloxone is a medication that is specifically designed to block the effects of opioids on the central nervous system (CNS).
It is a competitive antagonist, which means that it binds to opioid receptors in the brain and prevents opioids from binding to those receptors.
This can reverse the effects of opioids, such as respiratory depression, sedation, and hypotension.
Naloxone is often used to treat opioid overdose, but it can also be used to prevent opioid-induced respiratory depression in patients who are receiving opioids for pain relief.
Choice C rationale:
Naloxone is not effective in treating nausea.
In fact, it can actually worsen nausea in some patients.
This is because naloxone can block the effects of opioids in the brain, and opioids can sometimes have a nausea-relieving effect.
Choice D rationale:
Naloxone is not effective in treating urinary retention.
Urinary retention is a common side effect of opioids, but it is not caused by the effects of opioids on the CNS. Urinary retention is typically caused by the effects of opioids on the bladder muscles.

Correct Answer is D
Explanation
NPO status (nothing by mouth) is not a relevant intervention in this situation. It would be indicated for a patient with gastrointestinal issues or prior to a procedure, but it does not address the potential consequences of rapid fluid administration.
Restricting oral intake would not reverse or mitigate the effects of fluid overload that may have already occurred.
It's important to prioritize assessment of the patient's respiratory status, as fluid overload can lead to pulmonary edema, a serious complication.
Rationale for Choice B:
Elevating the head of the bed to high Fowler's position can be helpful in easing breathing for patients with respiratory distress, but it's not the most immediate priority in this case.
Assessing the patient's respiratory status directly through respiratory rate and lung sounds will provide more comprehensive information about potential fluid overload and guide further interventions.
Rationale for Choice C:
Measuring the client's temperature is not directly relevant to the concern of rapid fluid administration.
While fever could be a sign of infection, which might warrant fluid administration, it's not the primary concern in this scenario.
The priority is to assess for potential fluid overload, which could manifest as respiratory distress. Rationale for Choice D:
Checking the client's respiratory rate and lung sounds is the most appropriate action for the nurse to take in this situation.
Rapid infusion of 900 mL of fluid within a short period could lead to fluid overload, which can manifest as: Increased respiratory rate
Crackles in the lungs Shortness of breath Hypoxia
Early identification of these signs is crucial for prompt intervention and prevention of serious complications.
Correct Answer is C
Explanation
Choice A rationale:
Bilateral flank pain is not a typical sign of an allergic blood transfusion reaction. It can be associated with other conditions, such as kidney problems, musculoskeletal issues, or abdominal aortic aneurysm. While it's important to assess flank pain, it doesn't directly suggest an allergic reaction to the transfusion.
Choice B Rationale:
Distended jugular veins can indicate fluid overload, which could potentially occur during a transfusion. However, it's not a specific sign of an allergic reaction. Fluid overload can result from various causes, including heart failure, kidney problems, or excessive fluid intake. It's crucial to monitor for fluid overload during transfusions, but it doesn't definitively point to an allergic reaction.
Choice C Rationale:
Generalized urticaria, or hives, is a hallmark sign of an allergic reaction. It's characterized by raised, red, itchy welts that can appear on various parts of the body. Hives can develop rapidly and spread extensively. During a blood transfusion, generalized urticaria strongly suggests that the patient's immune system is reacting to a component of the transfused blood, such as proteins or antibodies.
Choice D Rationale:
Blood pressure 184/92 mm Hg is elevated and could be concerning, but it's not specific to allergic reactions. High blood pressure can have various causes, including stress, pain, anxiety, or underlying hypertension. While monitoring blood pressure during transfusions is essential, it doesn't directly indicate an allergic reaction.
