1. A 34-year-old female has recently been diagnosed with an autoimmune disease. She has also recently discovered that she is pregnant. Which of the following is the only immunoglobulin that will provide protection to the fetus in the womb?
- A. IgA
- B. IgD
- C. IgE
- D. IgG
Correct answer: D
Rationale: IgG is the only immunoglobulin that can cross the placental barrier, providing passive immunity to the fetus. About 70-80% of the immunoglobulins in the blood are IgG. Specific IgG antibodies are generated after an initial exposure to an antigen, offering long-term protection against microorganisms. IgG antibodies are critical for protecting the fetus as they can be rapidly reproduced upon re-exposure to the same antigen. IgA is primarily found in mucosal areas, IgD is involved in antigen recognition, and IgE is associated with allergic reactions, but they do not provide the same level of protection to the fetus as IgG.
2. A man has been taking lisinopril for CHF. The patient is seen in the emergency room for persistent diarrhea. The nurse is concerned about which side effect of lisinopril?
- A. Vertigo
- B. Hypotension
- C. Palpitations
- D. Nagging, dry cough
Correct answer: B
Rationale: The correct answer is 'Hypotension.' Lisinopril, an ACE inhibitor commonly used for CHF, can cause hypotension as a side effect. Persistent diarrhea can lead to dehydration, increasing the risk of hypotension in this patient. Vertigo (choice A) is not a typical side effect of lisinopril. Palpitations (choice C) are not directly associated with lisinopril use. A nagging, dry cough (choice D) is a common side effect of ACE inhibitors like lisinopril, but in this case, the patient's presentation with persistent diarrhea would make hypotension a more immediate concern.
3. The nurse is caring for a 73-year-old man with cirrhosis. Which data obtained by the nurse during the assessment will be of most concern?
- A. The patient complains of right upper-quadrant pain upon palpation.
- B. The patient's hands flap back and forth when the arms are extended.
- C. The patient has ascites and a 2-kg weight gain from the previous day.
- D. The patient's skin has multiple spider-shaped blood vessels on the abdomen.
Correct answer: B
Rationale: The most concerning data obtained by the nurse is the patient's hands flapping back and forth when the arms are extended, indicating asterixis, which is associated with hepatic encephalopathy. This condition can progress to hepatic coma and requires immediate attention. The presence of spider angiomas and right upper-quadrant abdominal pain are common findings in cirrhosis and do not warrant urgent intervention. Although ascites and weight gain suggest the need for treatment, they are not as alarming as the neurologic manifestations seen in hepatic encephalopathy.
4. In a pediatric clinic, a nurse is assessing a child recently diagnosed with cystic fibrosis. Which of the following later findings of this disease would the nurse not expect to see at this time?
- A. Positive sweat test
- B. Bulky greasy stools
- C. Moist, productive cough
- D. Meconium ileus
Correct answer: C
Rationale: In a child newly diagnosed with cystic fibrosis (CF), noisy respirations and a dry, non-productive cough are typically the first respiratory signs to appear. The other options, including a positive sweat test, bulky greasy stools, and meconium ileus, are among the earliest findings of CF. CF is a genetic condition that affects the production of mucus, sweat, saliva, and digestive juices. Due to a defective gene, these secretions become thick and sticky instead of thin and slippery, leading to blockages in various passageways, especially in the pancreas and lungs. Respiratory failure is a severe consequence of CF, making it crucial to monitor respiratory symptoms closely in affected individuals. Therefore, a moist, productive cough would not be an expected finding in a newly diagnosed child with CF.
5. A newborn infant in the nursery has developed vomiting, poor feeding, lethargy, and respiratory distress, and has been diagnosed with necrotizing enterocolitis. Which of the following nursing interventions is most appropriate for this infant?
- A. Feed the infant 30 cc of sterile water
- B. Position the infant on his back
- C. Administer antibiotics as ordered
- D. Allow the infant to breastfeed
Correct answer: C
Rationale: Necrotizing enterocolitis (NEC) is a serious condition characterized by ischemic bowel, leading to gastrointestinal symptoms, lethargy, poor feeding, and respiratory distress. In the management of NEC, it is crucial to stop oral feedings, insert a nasogastric tube for decompression, and administer antibiotics as prescribed by the physician. Therefore, the most appropriate nursing intervention for an infant with NEC is to administer antibiotics as ordered. Choice A, feeding the infant sterile water, is incorrect because oral feedings should be stopped in NEC. Choice B, positioning the infant on his back, is not directly related to the treatment of NEC. Choice D, allowing the infant to breastfeed, is contraindicated in NEC as oral feedings should be ceased to prevent further complications.
