Pediatric Research Questions Questions
Question 1 of 5
A narcotic analgesic is ordered for postoperative pain. Why are narcotics given in low doses to the laryngectomy patient?
Correct Answer: A
Rationale: Narcotic analgesics, when given in high doses, can depress the respiratory rate and cough reflex in patients. Laryngectomy patients have had their larynx removed and may already have compromised respiratory function. Therefore, giving narcotics in low doses helps to minimize the risk of further respiratory depression in these patients. It is important to closely monitor respiratory status when administering narcotics to laryngectomy patients to prevent potential complications.
Question 2 of 5
A patient with a history of endocarditis is undergoing a bowel resection. The nurse explains that the prophylactic antibiotics prevent which of the following?
Correct Answer: A
Rationale: Prophylactic antibiotics are given to prevent the recurrence or complications of endocarditis in patients with a history of the condition. Endocarditis is an infection of the inner lining of the heart chambers and valves. One of the serious complications of endocarditis is the formation of vegetative emboli, which are clusters of bacteria and fibrin that can break off and travel through the bloodstream, potentially causing blockages in various organs. By preventing endocarditis, the antibiotics also help reduce the risk of vegetative emboli formation during surgical procedures or other situations where bacteria may enter the bloodstream. Therefore, the nurse's explanation to the patient about the prophylactic antibiotics is focused on preventing complications related to endocarditis, including the formation of vegetative emboli.
Question 3 of 5
Immunity to a disease after recovery is possible because the first exposure to the pathogen has stimulated the formation of which of the following?
Correct Answer: C
Rationale: Immunity to a disease after recovery is possible because the first exposure to the pathogen has stimulated the formation of memory cells. Memory cells are a type of immune cell that "remembers" the specific pathogen encountered during the initial infection. When the same pathogen tries to infect the individual again, these memory cells quickly recognize the pathogen and mount a faster and stronger immune response, leading to a quicker recovery and preventing the person from getting sick again from the same pathogen. This immune memory is the basis of acquired immunity, providing long-lasting protection against future infections by the same pathogen.
Question 4 of 5
A patient who was walking in the woods disturbed a beehive, was stung, and was taken to the emergency department immediately due to allergies to bee stings. Which of the ff. symptoms would the nurse expect to see upon admission of this patient? i.Pallor around the sting bites iv. Retinal hemorrhage ii.Numbness and tingling in the extremities v. Tachycardia iii.Respiratory stridor vi. Dyspnea
Correct Answer: B
Rationale: The nurse would expect to see respiratory stridor (iii), tachycardia (v), and dyspnea (vi) upon admission of the patient who was stung by a bee, particularly if the patient has allergies to bee stings. These symptoms are indicative of an allergic reaction, which can progress to anaphylaxis in severe cases. Symptoms such as pallor around the sting bites (i), retinal hemorrhage (iv), and numbness and tingling in the extremities (ii) are not typically associated with an allergic reaction to a bee sting.
Question 5 of 5
Which of the following would the nurse evaluate as laboratory data that support the occurrence of AIDS?
Correct Answer: D
Rationale: The nurse would evaluate 200 CD 4+ cells as laboratory data that support the occurrence of AIDS. In patients with AIDS, there is a significant decrease in the CD4+ T-lymphocyte count, typically falling below 200 cells/mm³. This low CD4+ cell count increases the risk of opportunistic infections and indicates severe immune suppression, which is characteristic of AIDS. A CD4+ count of 200 or less is an important criterion for the diagnosis of AIDS according to the Centers for Disease Control and Prevention (CDC) and World Health Organization (WHO) guidelines.
