A patient with a severe fungal infection demonstrates impaired neutrophil function. Which of the following cellular processes is most likely to be affected in this patient?

Correct Answer: A

Rationale: Neutrophils are a type of white blood cell that play a crucial role in immune defense against pathogens, particularly in phagocytosis - the process by which they engulf and destroy invading microorganisms. In a severe fungal infection, impaired neutrophil function would most likely affect their ability to effectively perform phagocytosis, leading to a compromised immune response against the fungal pathogen. This would result in increased susceptibility to the infection and potentially severe outcomes for the patient. Antibody production, cytokine secretion, and mast cell degranulation are important components of the immune response, but neutrophils are primarily responsible for phagocytosis in the innate immune system.

Correct Answer: A

Rationale: In cases of poisoning, the main goals are to inactivate the poison to prevent further harm, administer the specific antidote if available to counteract the effects of the poison, and support vital organ functions to help the patient recover. Inducing the patient to vomit (III) is not always recommended as it can potentially cause more harm, especially if the ingested substance is corrosive. Therefore, the most appropriate goals in poisoning are to inactivate the poison, administer the specific antidote, and support vital organ functions.

Correct Answer: B

Rationale: The nurse's best response to a patient expressing fear of the unknown regarding an upcoming surgical procedure is to provide the patient with accurate information about the surgical procedure and what to expect. This approach empowers the patient with knowledge and helps alleviate anxiety by demystifying the unknown. By educating the patient about the procedure, potential risks, and postoperative care, the nurse can help the patient feel more prepared and in control of the situation. It is crucial for healthcare providers to address patient fears with compassion, understanding, and information to support the patient through the surgical process.

Correct Answer: D

Rationale: Administering oxygen inhalation is the priority nursing action for a patient presenting with clinical manifestations related to endocrine disorders. Patients with hyperthyroidism, Cushing syndrome, and hypothyroidism can all experience respiratory distress due to various reasons such as thyroid storm, adrenal crisis, or myxedema coma. Oxygen inhalation helps improve oxygenation and tissue perfusion, providing immediate support to the patient's respiratory system. It is crucial to ensure adequate oxygenation before addressing other assessments or interventions. Once the patient's breathing is stabilized, further assessments and treatments can be initiated as necessary.

Correct Answer: B

Rationale: When a patient receiving palliative care for end-stage cancer experiences severe nausea and vomiting despite current antiemetic therapy, the palliative nurse should consider switching to a different antiemetic medication with a different mechanism of action. This approach is based on the concept of individual variability in response to medications, as well as the potential development of tolerance to a particular drug. Switching to a different antiemetic with a new mechanism of action can provide the patient with a fresh chance at better symptom control by targeting different receptors or pathways involved in nausea and vomiting. It is important to consult the healthcare team and consider the patient's overall condition and medication history before making any changes in the treatment plan.

Correct Answer: C

Rationale: The main source of nutrition for the baby during pregnancy is the placenta. The placenta is an organ that develops inside the uterus during pregnancy and provides essential nutrients and oxygen from the mother's blood to the baby through the umbilical cord. It acts as a barrier, protecting the baby from harmful substances while allowing necessary nutrients to pass through. The amniotic fluid serves as a protective cushion for the baby, the uterus provides the space for the baby to grow, and chorionic villi are small, hair-like structures on the placenta that aid in the exchange of nutrients and waste between the mother and the baby. However, the primary source of nutrition for the baby is the placenta, making option C the correct answer in this scenario.

Correct Answer: A

Rationale: Pressure injuries on the heels are a concern as they can develop quickly and lead to serious complications, especially in surgical patients who are immobile for extended periods. Applying pressure-relieving devices, such as heel protectors or foam dressings, can help alleviate the pressure on the affected areas and prevent further damage. These devices are designed to distribute pressure evenly and reduce the risk of pressure injuries. It is important for the nurse to address the issue promptly to prevent additional harm to the patient's skin integrity.

Correct Answer: B

Rationale: Risk management in a healthcare facility involves identifying, assessing, and minimizing risks to prevent potential harm to patients and reduce liability issues. A planned program of loss prevention and liability control falls under the umbrella of risk management. This program includes strategies to mitigate risks such as patient safety protocols, infection control measures, staff training, and proper documentation practices to minimize legal liabilities. By implementing risk management practices, healthcare facilities aim to provide safe and high-quality care to their patients while also protecting themselves against potential legal challenges.

Correct Answer: C

Rationale: Choosing option C, asking the patient about their cultural beliefs and preferences related to pain, demonstrates cultural competence in pain assessment. Pain experiences can vary greatly across different cultures, and a patient's cultural background can influence how they perceive and express pain. By inquiring about the patient's cultural beliefs and preferences, the nurse can gain a better understanding of the patient's perspective on pain. This information is crucial for providing individualized and culturally sensitive pain management interventions. It also shows respect for the patient's unique cultural background and helps build a trusting and collaborative relationship between the nurse and the patient.
