Question 1 of 9

Which of the following cellular receptors is responsible for recognizing pathogen-associated molecular patterns (PAMPs) and initiating innate immune responses?

Correct Answer: A

Rationale: Toll-like receptors (TLRs) are a group of cellular receptors responsible for recognizing pathogen-associated molecular patterns (PAMPs), which are molecular components commonly found on pathogens like bacteria and viruses. When TLRs recognize these PAMPs, they initiate signaling pathways that trigger the innate immune response, leading to inflammation, antimicrobial defense, and the activation of adaptive immunity. B cell receptors (BCRs) and T cell receptors (TCRs) are involved in adaptive immune responses and recognize specific antigens rather than PAMPs. Fc receptors primarily bind to the Fc portion of antibodies and are involved in antibody-mediated immune responses. Thus, TLRs specifically play a critical role in sensing and responding to pathogens through the recognition of PAMPs.

Question 2 of 9

The PRIORITY nursing action of the nurse for Jose due for oxygen therapy is _____.

Correct Answer: C

Rationale: The PRIORITY nursing action of the nurse for Jose due for oxygen therapy is to turn on the oxygen. Ensuring that the oxygen is turned on is the necessary first step before any other actions can be effective in delivering oxygen to the patient. Without oxygen being turned on, all other steps such as attaching the humidifier, connecting tubing, or adjusting the flow rate would be ineffective in providing the necessary oxygen therapy to the patient. Therefore, turning on the oxygen is the most crucial initial step to take in this situation to ensure that the patient receives the needed oxygen promptly and safely.

A patient presents with chest pain that worsens with inspiration and is relieved by sitting forward. There is also evidence of deep vein thrombosis (DVT) in the lower extremity. Which cardiovascular disorder is most likely responsible for these symptoms?

Correct Answer: B

Rationale: The patient's presenting symptoms of chest pain worsened by inspiration and relieved by sitting forward, with associated DVT in the lower extremity, suggest a high likelihood of pulmonary embolism. Chest pain that worsens with inspiration due to pleuritic involvement is a classic symptom of pulmonary embolism. Additionally, the presence of DVT in the lower extremity represents a risk factor for the development of pulmonary embolism, as clots originating in the deep veins can travel to the pulmonary circulation to cause an obstruction. Patients with pulmonary embolism may also exhibit signs of right heart strain, such as tachycardia, tachypnea, and sometimes hemoptysis.

Question 4 of 9

The nurse prepares a care plan for the patient. Based on Ramona Mercer's becoming a mother (BAM) theory, which of the following statements fosters the process of becoming a mother?

Correct Answer: B

Rationale: Ramona Mercer's becoming a mother (BAM) theory emphasizes the dynamic transformation and evolution of a woman's persona as she transitions into motherhood. This theory acknowledges that becoming a mother is a process involving significant changes in a woman's identity, roles, and relationships. It goes beyond just the physical aspects of giving birth and delves into the psychological, emotional, and social aspects of motherhood. Therefore, statement B aligns with the core principles of Mercer's BAM theory and fosters the understanding of the process of becoming a mother.

Question 5 of 9

The patient verbalizes to the nurse about thought to kill his wife". The nurse is in dilemma whether to tell the wife about this Conversation. Given this situation which of the following is the appropriate action of the nurse?

Correct Answer: A

Rationale: In this critical situation, the safety of the wife is of utmost importance. Whenever a healthcare provider becomes aware of a direct threat to someone's safety, especially related to potential harm or violence, it is their ethical and legal responsibility to report this information to the appropriate authorities promptly. In this case, the nurse should alert the proper authorities, such as law enforcement or a mental health crisis team, to ensure that immediate steps are taken to protect the wife from harm. Confidentiality should be breached in situations where there is a clear threat to an individual's safety. Keeping the information confidential in this scenario could result in serious harm or even loss of life. The nurse must act quickly to protect the potential victim.

Question 6 of 9

Three hours postpartum, a primiparous patient's fundus is firm and midline. On perineal inspection by Nurse Kayla, she observes a small constant trickle of blood. What will thee nurse suspect for the patient to have?

Correct Answer: B

Rationale: In this scenario, the firm and midline fundus at three hours postpartum indicates that the uterus is contracting well. The presence of a small constant trickle of blood on perineal inspection suggests ongoing bleeding. This combination of findings is concerning for retained placenta, where a portion of the placenta remains attached to the uterine wall and prevents proper contraction and closure of the blood vessels at the placental site. Retained placenta can lead to postpartum hemorrhage and requires prompt evaluation and intervention to prevent complications. Nurse Kayla should escalate this finding to the healthcare provider for further assessment and management.

Question 7 of 9

During the surgical procedure, the nurse notices a break in sterile technique by a member of the surgical team. What should the nurse do?

Correct Answer: C

Rationale: In this situation, it is crucial for the nurse to inform the surgeon immediately and request corrective action. Maintaining a sterile field during surgical procedures is essential to prevent infections and ensure patient safety. Any break in sterile technique should be addressed promptly to prevent any potential harm to the patient. By informing the surgeon immediately, corrective action can be taken promptly to maintain the sterility of the surgical field and minimize the risk of complications. Reporting the incident to the surgeon also allows for immediate intervention and re-education of the team member involved in the break in sterile technique.

Question 8 of 9

Sandro is taking pemoline (Cylert) for ADHD. The nurse must be aware of which of the following side effects?

Correct Answer: D

Rationale: Pemoline (Cylert) is a central nervous system stimulant used in the treatment of ADHD. One of the significant potential side effects of pemoline is hepatotoxicity, which can manifest as elevated liver function test results. Therefore, the nurse must monitor the patient's liver function regularly while they are taking pemoline to monitor for any signs of liver damage or dysfunction. It is essential to educate the patient about the signs and symptoms of liver problems, such as jaundice (yellowing of the skin or eyes), abdominal pain, nausea, or dark urine, and to report any such symptoms immediately to their healthcare provider. Regular monitoring and early detection of liver function abnormalities can help prevent severe liver damage in patients taking pemoline.

Question 9 of 9

Nurse Roberto is aware that a client who has experienced cardiac arrest is MOST at risk for which of the following imbalances?

Correct Answer: D

Rationale: When a client experiences cardiac arrest, their breathing may become insufficient, leading to inadequate elimination of carbon dioxide (CO2) from the body. With reduced CO2 elimination, the level of CO2 in the bloodstream increases, causing respiratory acidosis. This imbalance is characterized by a decrease in blood pH along with an increase in CO2 levels in the blood, resulting in an acidic environment. Respiratory acidosis is the most common imbalance seen in clients who have experienced cardiac arrest, as impaired gas exchange impacts the body's ability to maintain proper acid-base balance.
