Nursing Elites

1. A child is diagnosed with Hirschsprung's disease. The nurse is teaching the parents about the cause of the disease. Which statement, if made by the parent, supports that teaching was successful?

• A. The absence of special cells in the rectum caused the disease.
• B. Incomplete digestion of the protein part of wheat, barley, rye, and oats is not the cause of the disease.
• C. The disease does not occur due to increased bowel motility leading to spasm and pain.
• D. The disease is not caused by the inability to tolerate sugar found in dairy products.

Correct answer: A

Rationale: Hirschsprung's disease, also known as congenital aganglionosis or megacolon, is characterized by the absence of ganglion cells in the rectum and, sometimes, extending into the colon. Choice A correctly explains the cause of Hirschsprung's disease. Choice B is incorrect as it describes celiac disease, which is related to gluten intolerance. Choice C is inaccurate as it describes symptoms of irritable bowel syndrome, not the cause of Hirschsprung's disease. Choice D is wrong as it pertains to lactose intolerance, not Hirschsprung's disease.

2. A patient is diagnosed with both human immunodeficiency virus (HIV) and active tuberculosis (TB) disease. Which information obtained by the nurse is most important to communicate to the healthcare provider?

• A. The Mantoux test induration measured 7 mm.
• B. The chest x-ray revealed infiltrates in the lower lobes.
• C. The patient is receiving antiretroviral therapy for HIV infection.
• D. The patient has a cough producing blood-tinged mucus.

Correct answer: C

Rationale: The most critical information to communicate to the healthcare provider in a patient diagnosed with both HIV and active TB disease is that the patient is receiving antiretroviral therapy for HIV infection. This is crucial because drug interactions can occur between antiretrovirals used to treat HIV infection and medications used to treat TB. By informing the healthcare provider about the antiretroviral therapy, potential interactions can be assessed and managed effectively to optimize patient care. The other data provided, such as the Mantoux test result, chest x-ray findings, and presence of blood-tinged mucus, are important clinical information but are expected in a patient with coexisting HIV and TB and do not directly impact potential drug interactions between antiretrovirals and TB medications.

3. A nurse is caring for a 2-day-old infant who has a bilirubin level of 19 mg/dl. The physician has ordered phototherapy. Which of the following actions indicates correct preparation of the infant for this procedure?

• A. Undress the baby down to a diaper and hat
• B. Place the baby in his mother's arms before turning on the light
• C. Position the phototherapy light approximately 3 inches above the baby's skin
• D. Secure eye protection for the infant without occluding the nose

Correct answer: D

Rationale: Phototherapy is used to treat high levels of bilirubin among infants, typically evidenced as jaundice. The nurse must position the infant carefully during this procedure to maximize the benefits of the light therapy while protecting the baby. Placing protective eyewear over the baby's eyes without covering the nose is crucial to shield the eyes from the ultraviolet light. Undressing the baby down to a diaper and hat (Choice A) is a standard practice to maximize skin exposure to the phototherapy light. Placing the baby in his mother's arms before turning on the light (Choice B) is not necessary for the preparation of the infant for phototherapy. Positioning the phototherapy light approximately 3 inches above the baby's skin (Choice C) is incorrect as the distance should be as recommended by the healthcare provider based on the manufacturer's instructions.

4. What is the likely cause of pericarditis in a young patient?

• A. Heart failure
• B. Acute MI
• C. Hypertension
• D. Infectious processes

Correct answer: D

Rationale: In younger patients, pericarditis is typically caused by an infection commonly triggered by viruses like the Coxsackie virus, streptococcus, staphylococcus, or Haemophilus influenzae. Infectious processes are the leading cause of pericarditis in younger individuals. Heart failure, Acute MI, and Hypertension are not common causes of pericarditis in young patients. In older adults, acute myocardial infarction (MI) is a more common cause of pericarditis.

5. The nurse caring for Mrs. J is prepared to suction her endotracheal tube. Which of the following interventions will reduce hypoxia during this procedure?

• A. Hyperoxygenate Mrs. J for up to 60 seconds prior to starting
• B. Administer 15 mL of sterile fluid into the tube prior to suctioning
• C. Suction for no longer than 30 seconds at a time
• D. Wait 30 seconds after suctioning before attempting again

Correct answer: A

Rationale: Before suctioning a client's endotracheal tube, it is essential to hyperoxygenate the client for approximately 30 to 60 seconds. Hyperoxygenation helps increase oxygen delivery to the tissues, reducing the risk of hypoxia during and after the suctioning procedure. Administering fluid into the tube before suctioning (Choice B) is unnecessary and can lead to complications. Suctioning for no longer than 30 seconds at a time (Choice C) is a general guideline but does not specifically address reducing hypoxia. Waiting 30 seconds after suctioning before attempting again (Choice D) may lead to inadequate oxygenation and potential hypoxia, making it less effective in preventing this complication compared to hyperoxygenation prior to suctioning.
