1. The nurse is caring for a client with a serum potassium level of 3.5 mEq/L. The client is placed on a cardiac monitor and receives 40 mEq potassium chloride in 1000 ml of 5% dextrose in water IV. Which of the following EKG patterns indicates to the nurse that the infusions should be discontinued?
- A. Narrowed QRS complex
- B. Shortened "PR"? interval
- C. Tall peaked "T"? waves
- D. Prominent "U"? waves
Correct answer: C
Rationale: A tall peaked T wave is a characteristic EKG pattern associated with hyperkalemia. Hyperkalemia refers to high levels of potassium in the blood, which can lead to cardiac arrhythmias and other serious complications. Tall peaked T waves are a red flag for potential cardiac issues and can indicate the need to discontinue potassium infusions. The other choices, such as narrowed QRS complex, shortened "PR"? interval, and prominent "U"? waves, are not typically associated with hyperkalemia. Therefore, recognizing tall peaked T waves is crucial for the nurse to take prompt action in managing the client's condition.
2. An alcoholic and homeless patient is diagnosed with active tuberculosis (TB). Which intervention by the nurse will be most effective in ensuring adherence with the treatment regimen?
- A. Arrange for a friend to administer the medication on schedule.
- B. Give the patient written instructions about how to take the medications.
- C. Teach the patient about the high risk for infecting others unless treatment is followed.
- D. Arrange for a daily noon meal at a community center where the drug will be administered
Correct answer: D
Rationale: Directly observed therapy is the most effective means for ensuring compliance with the treatment regimen for a homeless patient with active tuberculosis. By arranging a daily noon meal at a community center where the drug will be administered, the nurse ensures that the patient is available to receive the medication and can directly observe the patient taking it. This method helps address the challenges faced by homeless individuals, such as lack of a stable living situation. The other options, such as having a friend administer the medication, giving written instructions, or educating about infecting others, may not be as effective in ensuring adherence, especially in the case of a homeless individual with alcoholism.
3. A patient is being treated in the Neurology Unit for Meningitis. Which of these is a priority assessment for the nurse to make?
- A. Assess the patient for nuchal rigidity
- B. Determine the patient's past exposure to infectious organisms
- C. Check the patient's WBC lab values
- D. Monitor for increased lethargy and drowsiness
Correct answer: D
Rationale: Monitoring for increased lethargy and drowsiness is crucial as these symptoms indicate a decreased level of consciousness, which is the cardinal sign of increased Intracranial Pressure (ICP). Elevated ICP can lead to serious complications and requires immediate intervention. Assessing for nuchal rigidity is important in suspected cases of meningitis but monitoring lethargy and drowsiness takes precedence due to its direct correlation with ICP. Determining past exposure to infectious organisms and checking WBC lab values are important for diagnosing and treating meningitis but do not directly address the immediate concern of increased ICP.
4. Parents of a 6-month-old breastfed baby ask the nurse about increasing the baby's diet. Which of the following should be added first?
- A. Cereal
- B. Eggs
- C. Meat
- D. Juice
Correct answer: A
Rationale: The correct answer is 'Cereal.' The guidelines of the American Academy of Pediatrics recommend introducing one new food at a time, starting with strained cereal. Cereal is often recommended as a first solid food for infants due to its soft texture and iron-fortified properties, which are important for the baby's development. Eggs and meat are common allergenic foods and are usually introduced later. Juice is not recommended for infants under 1 year old due to its high sugar content and lack of nutritional value compared to whole fruits.
5. The clinic nurse reviews the record of an infant and notes that the primary health care provider (PHCP) has documented a diagnosis of suspected Hirschsprung's disease. The nurse reviews the assessment findings documented in the record, knowing that which sign most likely led the mother to seek health care for the infant?
- A. Diarrhea
- B. Projectile vomiting
- C. Regurgitation of feedings
- D. Constipation
Correct answer: C
Rationale: Hirschsprung's disease, also known as congenital aganglionosis or aganglionic megacolon, is characterized by the absence of ganglion cells in the rectum and other parts of the affected intestine. Clinical manifestations of Hirschsprung's disease include chronic constipation with pellet-like or ribbon-like foul-smelling stools, delayed or absent passage of meconium in the neonatal period, bowel obstruction (especially in the neonatal period), abdominal pain and distention, and failure to thrive. In the case of an infant with suspected Hirschsprung's disease, regurgitation of feedings is a sign that may have led the mother to seek healthcare. This symptom can be associated with the bowel dysfunction and obstruction seen in Hirschsprung's disease. Options A, B, and D are not typically associated with Hirschsprung's disease. Diarrhea is not a common symptom, projectile vomiting is not a typical presentation, and constipation, while a symptom of the disease, is not the sign that would most likely prompt a visit to seek healthcare in an infant suspected of having Hirschsprung's disease.
