NCLEX RN Practice Questions Quizlet
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. The parent of an infant diagnosed with gastroesophageal reflux disease is receiving feeding instructions from the nurse. Which instruction should the nurse give to the parent to assist in reducing the episodes of emesis?
- A. Provide smaller, more frequent feedings.
- B. Burp the infant frequently during feedings.
- C. Thin the feedings by adding water to the formula.
- D. Thicken the feedings by adding rice cereal to the formula.
Correct answer: D
Rationale: Gastroesophageal reflux disease involves the backward flow of gastric contents into the esophagus due to sphincter issues. To reduce episodes of emesis, it is recommended to thicken feedings by adding rice cereal to the formula. This helps to weigh down the contents in the stomach, making regurgitation less likely. Providing smaller, more frequent feedings and burping the infant frequently are beneficial strategies for gastroesophageal reflux. However, in this case, thickening the feedings is the most appropriate intervention. Thinning the feedings by adding water to the formula is not recommended as it can decrease the caloric density of the formula and may not help in reducing reflux.
3. 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.
4. A nurse is assessing a client who is post-op day #3 after an abdominal hernia repair. After a bout of harsh coughing, the client states, 'it feels like something gave way.' The nurse assesses his abdomen and notes an evisceration from the surgical site. What is the next action of the nurse?
- A. Turn the client on his side
- B. Push the abdominal contents back inside the wound using sterile gloves
- C. Ask the client to take a breath and hold it
- D. Cover the intestine with sterile saline dressings
Correct answer: D
Rationale: A wound evisceration occurs when the edges of an abdominal wound separate, allowing the coils of the intestine to protrude outside of the body. The nurse should notify the physician at once if this occurs. While waiting for treatment, the nurse should cover the intestines with sterile gauze soaked in saline. Turning the client on his side or asking the client to take a breath and hold it are not appropriate actions in this situation. Pushing the abdominal contents back inside the wound using sterile gloves can lead to infection and is not within the nurse's scope of practice.
5. What would be the most appropriate follow-up by the home care nurse for a 57-year-old male client with a hemoglobin of 10 g/dl and a hematocrit of 32%?
- A. Ask the client if he has noticed any bleeding or dark stools
- B. Tell the client to call 911 and go to the emergency department immediately
- C. Schedule a repeat Hemoglobin and Hematocrit in 1 month
- D. Tell the client to schedule an appointment with a hematologist
Correct answer: A
Rationale: The correct answer is to ask the client if he has noticed any bleeding or dark stools. Normal hemoglobin for males is 13.0 - 18 g/dl, and normal hematocrit for males is 42 - 52%. The values of hemoglobin and hematocrit provided for the client are below normal, indicating mild anemia. The first step for the nurse is to inquire about any signs of bleeding or changes in stools that could suggest bleeding from the gastrointestinal tract. This helps in assessing the possible cause of the low hemoglobin and hematocrit levels. The other options are not appropriate as calling 911 and going to the emergency department immediately is not warranted for mild anemia, scheduling a repeat test in 1 month delays addressing the current concern, and referring the client to a hematologist may be premature without investigating the cause of the low levels first.
