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

Answer and Explanation

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 B

Explanation

Choice A rationale:

Incorrect. Patients have a legal right to access their medical records under the Health Information Portability and Accountability Act (HIPAA). Denying access is a violation of patient rights and could lead to legal consequences.

Undermines patient autonomy and trust. Patients have a right to know what information is in their medical records and to participate in their own healthcare decisions. Denying access can erode trust in the healthcare system.

Potential for errors and misunderstandings. If patients cannot review their records, they may not be able to identify errors or misunderstandings that could impact their care.

Choice B rationale:

Correct. This response upholds patient rights while ensuring that the request for access is documented and handled appropriately.

Protects patient privacy and confidentiality. The written request process helps to ensure that only the patient or their authorized representative has access to the records.

Provides a mechanism for tracking and auditing access requests. This can help to prevent unauthorized access and ensure compliance with HIPAA regulations.

Choice C rationale:

Incorrect. Patients have a right to access their records at any time, not just when they are being discharged.

Delays access to information. Patients may need to review their records to make informed decisions about their care, even if they are not being discharged.

Potential for records to be lost or misplaced. There is a risk that records could be lost or misplaced if they are not provided to the patient until discharge.

Choice D rationale:

Incorrect. Patients do not need to provide a reason for wanting to access their medical records.

Intrusive and unnecessary. Patients may feel uncomfortable or embarrassed about having to explain their reasons for wanting to access their records.

Potential for discrimination. Patients may be less likely to request access to their records if they feel that they will be judged or questioned about their reasons for doing so.

A. Cellular hypoxia B. Fluid retention C. Prolonged bleeding D. Impaired immunity

Correct Answer is A

Explanation

Choice A rationale:

Cellular hypoxia occurs when cells do not receive enough oxygen to meet their metabolic demands. Hemoglobin is the protein in red blood cells that carries oxygen from the lungs to the tissues. A hemoglobin level of 10.8 g/dL is below the normal range for adults (14-18 g/dL), indicating that the client has anemia. Anemia reduces the oxygen-carrying capacity of the blood, which can lead to cellular hypoxia.

Here is a detailed explanation of how anemia can lead to cellular hypoxia:

Decreased oxygen-carrying capacity: Anemia results in fewer red blood cells or reduced hemoglobin levels within those cells. As a consequence, the blood's ability to transport oxygen to the tissues is diminished.

Impaired oxygen delivery: Oxygen is transported to the tissues through the bloodstream, attached to hemoglobin within red blood cells. With fewer red blood cells or reduced hemoglobin, the delivery of oxygen to the tissues is compromised.

Decreased oxygen availability at the cellular level: As oxygen delivery is impaired, less oxygen is available to the cells for metabolic processes. This insufficient oxygen supply leads to cellular hypoxia.

Impaired cellular function: Cells require oxygen to produce energy through a process called aerobic respiration. Cellular hypoxia disrupts this process, leading to impaired cellular function.

Tissue and organ dysfunction: When a significant number of cells within a tissue or organ experience hypoxia, the function of that tissue or organ can be compromised. This can manifest in various symptoms and complications, depending on the affected organs.

Common signs and symptoms of cellular hypoxia:

Fatigue Weakness

Shortness of breath Pale skin

Dizziness Headache Chest pain

Tachycardia (rapid heart rate) Cognitive impairment
