A patient is going for a coronary arterial by-pass graft (CABG) due to a 4 blocked arterial blood vessels. A surgical team has been formed with the cardiac surgeon as the head. Who is the member of the health team that prepares the pre-operative orders for the patient?

Correct Answer: C

Rationale: The member of the health team responsible for preparing pre-operative orders for a patient undergoing surgery, such as a coronary arterial bypass graft (CABG), is typically the anesthesiologist. Anesthesiologists are specialized physicians who are trained to administer anesthesia and manage the patient's well-being during surgery. They are responsible for assessing the patient's medical history, determining the appropriate anesthesia plan, and prescribing pre-operative medications. Cardiologists focus on diagnosing and treating heart conditions, surgeons perform the actual surgical procedure, and medical internists specialize in the diagnosis and non-surgical treatment of internal diseases. The anesthesiologist plays a crucial role in ensuring the safety and comfort of the patient before, during, and after surgery.

Correct Answer: B

Rationale: Normal saline is the preferred solution for wound irrigation because it is isotonic and will not damage healthy tissue or delay wound healing. It helps to remove debris and pathogens from the wound, promoting a clean environment for healing. Sterile water can be used if normal saline is not available, but it may cause cellular damage if used in large volumes. Hydrogen peroxide and Betadine solution are not recommended for wound irrigation as they can be cytotoxic to the tissues and interfere with the wound healing process. It's important for the nurse to use evidence-based practice and follow recommended guidelines to promote optimal wound healing outcomes.

Correct Answer: D

Rationale: Third-degree perineal lacerations are significant injuries that require careful monitoring for signs of infection or wound dehiscence, which are potential complications that could hinder optimal wound healing. Signs of infection may include increased redness, warmth, swelling, pain, and purulent drainage from the wound site. Dehiscence refers to the separation of the wound edges, which can be a serious complication requiring immediate attention. By closely monitoring the incision site for these signs, the nurse can promptly intervene if any complications arise, ensuring proper healing and preventing further complications. While providing perineal care, proper application of peri-pads, and encouraging sitz baths are important for comfort and cleanliness, monitoring for complications takes priority in promoting optimal wound healing in this scenario.

Correct Answer: C

Rationale: Cryptosporidium parvum is a protozoan parasite that commonly causes waterborne illness characterized by watery diarrhea, abdominal cramps, and nausea. This parasite is often transmitted through contaminated water sources such as streams or lakes. Laboratory tests identifying oocysts in the stool sample are indicative of Cryptosporidium infection. Giardia lamblia can also cause similar symptoms, but the presence of oocysts points more towards Cryptosporidium in this case. Entamoeba histolytica causes amoebic dysentery with bloody diarrhea and is usually associated with fecal-oral transmission through contaminated food or water. Cyclospora cayetanensis typically causes prolonged watery diarrhea and is associated with the ingestion of contaminated food or water.

Correct Answer: C

Rationale: The most appropriate nursing action when a postpartum client presents with persistent, severe headache, photophobia, and altered mental status is to notify the healthcare provider immediately. These symptoms could be indicative of serious conditions such as postpartum preeclampsia or postpartum eclampsia, both of which require prompt medical evaluation and intervention. Delaying medical attention in such cases can lead to severe complications for the mother. Therefore, it is crucial to prioritize the client's safety and well-being by quickly involving the healthcare provider for further assessment and management.

Correct Answer: C

Rationale: Benzodiazepines are commonly prescribed for the management of insomnia due to their sedative effects. One of the most common adverse effects of benzodiazepines is daytime drowsiness, which can impair the patient's ability to function normally during the day. Monitoring the patient closely for daytime drowsiness is important to ensure their safety and well-being, as it can affect their daily activities and increase the risk of accidents or falls. It is essential for the nurse to educate the patient on the potential for daytime drowsiness and advise them to avoid activities that require full alertness, such as driving or operating heavy machinery, until they know how the medication affects them. If the patient experiences severe or persistent daytime drowsiness, the healthcare provider may need to adjust the dosage or consider alternative treatment options.

Correct Answer: B

Rationale: When managing a conscious patient with a foreign object lodged in the eye, the appropriate action is to rinse the eye with sterile saline solution. This helps to flush out the foreign object and reduce the risk of further injury or infection. Attempting to remove the object with tweezers or applying pressure to the eyelid can potentially cause more harm to the eye. Placing a bandage over the affected eye is not beneficial in this situation as it does not address the presence of the foreign object. Rinsing the eye with sterile saline solution is the safest and most effective initial step to take in managing a foreign object lodged in the eye.

Correct Answer: A

Rationale: Immunological memory is primarily maintained by the clonal expansion of memory B cells. Memory B cells are a type of long-lived immune cell that originates from previously activated B cells during an immune response to a pathogen. When the immune system encounters the same pathogen again, memory B cells can quickly recognize and respond to it by undergoing rapid clonal expansion and differentiation into plasma cells that produce specific antibodies. This quick and robust response leads to the more efficient elimination of the pathogen during secondary exposure, resulting in the faster and stronger immune response characteristic of immunological memory.

Correct Answer: B

Rationale: The assessment of a patient who has ingested poison must include determining the poison ingested and the amount (I), the time from ingestion and the signs and symptoms (II), as well as the weight of the patient (III). These factors are essential in evaluating the severity of the poisoning and determining the appropriate treatment plan. However, the patient's immunization history (IV) is not directly relevant to the assessment of ingested poison and thus is not essential in this context.
