Nursing Elites

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. 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.

3. The nurse is caring for a 10-year-old upon admission to the burn unit. One assessment parameter that will indicate that the child has adequate fluid replacement is

• A. Urinary output of 30 ml per hour
• B. No complaints of thirst
• C. Increased hematocrit
• D. Good skin turgor around burn

Correct answer: A

Rationale: The correct answer is urinary output of 30 ml per hour. In a 10-year-old child, this level of urinary output is indicative of adequate fluid replacement without suggesting overload. Monitoring urinary output is crucial in assessing fluid balance. Choices B, C, and D are incorrect. No complaints of thirst do not provide a direct assessment of fluid status. Increased hematocrit is a sign of dehydration, not adequate fluid replacement. Good skin turgor around the burn is a general assessment but may not directly reflect the child's overall fluid status.

4. To prevent a Valsalva maneuver in a client recovering from an acute myocardial infarction, the nurse would:

• A. Assist the client in using the bedside commode
• B. Administer stool softeners daily as prescribed
• C. Administer antidysrhythmics PRN as prescribed
• D. Maintain the client on strict bed rest

Correct answer: B

Rationale: Administering stool softeners daily as prescribed is essential to prevent straining during defecation, which can lead to a Valsalva maneuver. Straining can increase intra-abdominal pressure, hinder venous return, and elevate blood pressure, risking cardiac complications in a client recovering from a heart attack. Using a bedside commode might be useful to minimize exertion during toileting but does not directly address the risk of a Valsalva maneuver. Administering antidysrhythmics PRN is not the primary intervention for preventing a Valsalva maneuver; these medications are used to manage dysrhythmias if they occur. Keeping the client on strict bed rest is not the best option as early mobilization is encouraged in post-myocardial infarction recovery to prevent complications such as deep vein thrombosis and muscle weakness.

5. A 65-year-old man is prescribed Flomax (Tamsulosin) for Benign Prostatic Hyperplasia. The patient lives in an upstairs apartment. The nurse is most concerned about which side effect of Flomax?

• A. Hypotension
• B. Tachycardia
• C. Back Pain
• D. Difficulty Urinating

Correct answer: A

Rationale: The correct answer is 'Hypotension.' Flomax (Tamsulosin) is known to cause orthostatic hypotension, especially in the elderly, leading to a sudden drop in blood pressure when standing up. This side effect can result in dizziness, falls, and injury, especially concerning for a patient living in an upstairs apartment. Tachycardia (increased heart rate) and back pain are less commonly associated with Flomax use, while difficulty urinating is a symptom that Flomax is intended to improve in patients with Benign Prostatic Hyperplasia.
