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 C
Explanation
Choice A rationale:
A colostomy is a surgical opening in the abdomen that allows stool to pass through the colon and out of the body. While a colostomy may increase the risk of certain complications, such as dehydration and skin irritation, it does not directly increase the risk of aspiration. This is because the colostomy bypasses the upper digestive tract, where aspiration typically occurs.
Choice B rationale:
An ileostomy is a similar surgical opening in the abdomen, but it diverts the small intestine rather than the colon. Like a colostomy, an ileostomy does not directly increase the risk of aspiration. However, it may lead to dehydration and electrolyte imbalances, which could indirectly contribute to aspiration risk.
Choice C rationale:
Enteral feedings through an NG tube are a common way to provide nutrition to patients who cannot eat by mouth. However, these feedings can also increase the risk of aspiration. This is because the NG tube bypasses the normal swallowing mechanisms, which help to protect the airway. If the feeding tube is not properly positioned or if the patient has impaired gastric motility, formula could enter the lungs and cause aspiration pneumonia.
Choice D rationale:
A chest tube is a drainage tube that is inserted into the chest cavity to remove air or fluid. While a chest tube may cause some discomfort and respiratory issues, it does not directly increase the risk of aspiration.
Correct Answer is A
Explanation
Choice A rationale:
Painful urination (dysuria) can be a sign of several conditions that could potentially affect the client's IVP or indicate a need for further assessment. These conditions include:
Urinary tract infection (UTI): UTIs are common in clients with recurrent kidney stones, and they can cause inflammation and pain in the urinary tract. If a client has a UTI, it's important to treat it before the IVP to reduce the risk of spreading the infection to the kidneys.
Kidney stone passage: The client's history of kidney stones makes it possible that the pain could be due to the passage of a stone. This would be important information for the healthcare team to know, as it could affect the interpretation of the IVP results.
Other urological conditions: There are other urological conditions, such as bladder or urethral strictures, that can also cause painful urination. These conditions might also need to be considered and assessed for.
It's important for the nurse to collect more data about the client's painful urination to determine the underlying cause and whether it could impact the IVP. This might include asking questions about:
The severity and duration of the pain
Any other associated symptoms, such as fever, urgency, or frequency The client's history of UTIs or kidney stones
Any recent changes in urinary habits
Based on this additional information, the nurse can then collaborate with the healthcare team to determine the best course of action, which might include:
Further assessment, such as a urinalysis or urine culture Treatment for a UTI, if present
Pain management
Rescheduling the IVP, if necessary
