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. When assessing the respiratory system of an older patient, which finding indicates that the nurse should take immediate action?

• A. Weak cough effort
• B. Barrel-shaped chest
• C. Dry mucous membranes
• D. Bilateral crackles at lung bases

Correct answer: D

Rationale: Bilateral crackles at lung bases indicate a potential acute issue like heart failure. Immediate action is necessary in this situation. The nurse should conduct further assessments such as oxygen saturation and inform the healthcare provider promptly. A barrel-shaped chest and hyperresonance to percussion are typical signs of aging and do not require immediate action. A weak cough effort is common in older patients due to age-related changes, and dry mucous membranes are also expected in older individuals. While these findings may warrant further evaluation, they do not demand immediate action like bilateral crackles at lung bases.

3. Based on Mr. C's assessment, which of the following nursing interventions is most appropriate?

• A. Elevate the lower extremities to 45 degrees to promote venous return
• B. Place Mr. C in the Trendelenburg position
• C. Administer total parenteral nutrition
• D. Monitor urine output

Correct answer: D

Rationale: In the context of Mr. C's assessment, the most appropriate nursing intervention is to monitor urine output. A client in hypovolemic shock may experience decreased urine output due to poor kidney perfusion. By monitoring urine output, the nurse can assess renal function and fluid status. Administering total parenteral nutrition (Choice C) is not indicated based on the information provided, as the priority is to stabilize the client's condition. Elevating the lower extremities (Choice A) may be helpful in some cases but is not the priority in this situation. Placing Mr. C in the Trendelenburg position (Choice B) is contraindicated in hypovolemic shock as it can worsen venous return and compromise cardiac output.

4. An emergency department nurse is performing an assessment on a child with a suspected diagnosis of intussusception. Which assessment question for the parents will elicit the most specific data related to this disorder?

• A. Does the child have any food allergies?
• B. What do the bowel movements look like?
• C. Has the child eaten any food in the last 24 hours?
• D. Can you describe the type of pain that the child is experiencing?

Correct answer: D

Rationale: The correct answer is asking the parents to describe the type of pain the child is experiencing because a report of severe colicky abdominal pain in a healthy, thriving child between 3 and 17 months of age is the classic presentation of intussusception. Typical behavior includes screaming and drawing the knees up to the chest. This specific question helps in identifying the key symptom of intussusception. Choices A, B, and C are important aspects of a health history but are not specific to the diagnosis of intussusception. Food allergies, bowel movements, and recent food intake are relevant for a comprehensive assessment but do not directly relate to the specific symptoms of intussusception.

5. 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.
