Nursing Elites

1. When assessing a client’s heart sounds, the nurse hears a scratching sound during both systole and diastole. These sounds become more distinct when the nurse has the client sit up and lean forward. The nurse should document the presence of a:

• A. Pericardial friction rub
• B. Heart murmur
• C. S3 heart sound
• D. S4 heart sound

Correct answer: A

Rationale: A pericardial friction rub is characterized by a scratching sound that occurs during both systole and diastole. It becomes more distinct when the client is sitting up and leaning forward. This indicates an inflammation of the pericardial sac rubbing against the layers of the heart. Heart murmurs (choice B) are abnormal heart sounds caused by turbulent blood flow, not by friction like in a pericardial rub. S3 and S4 heart sounds (choices C and D) are additional heart sounds related to abnormal ventricular filling, not to pericardial friction rubs.

2. A nurse is planning care for a client who has hypernatremia. Which of the following actions should the nurse include in the plan of care?

• A. Infuse hypotonic IV fluids.
• B. Implement a fluid restriction.
• C. Increase sodium intake.
• D. Administer sodium polystyrene sulfonate.

Correct answer: A

Rationale: The correct answer is to infuse hypotonic IV fluids. In hypernatremia, there is an elevated sodium concentration in the blood, and diluting it with hypotonic fluids helps to lower the sodium levels. Implementing a fluid restriction or increasing sodium intake would worsen hypernatremia by further concentrating sodium in the body. Administering sodium polystyrene sulfonate is used for treating hyperkalemia, not hypernatremia.

3. Which serum blood finding in diabetic ketoacidosis alerts the nurse that immediate action is required?

• A. pH below 7.3
• B. Potassium of 5.0
• C. HCT of 60
• D. PaO2 of 79%

Correct answer: C

Rationale: A hematocrit (HCT) of 60 indicates severe dehydration, a critical condition in diabetic ketoacidosis that requires immediate intervention. Severe dehydration can lead to hypovolemic shock and organ failure. While a low pH below 7.3 is indicative of acidosis, it may not require immediate action compared to severe dehydration. A potassium level of 5.0 is within the normal range and not a critical finding in this scenario. PaO2 of 79% reflects oxygenation status, which is important but not the most critical finding requiring immediate action in diabetic ketoacidosis.

4. A school-aged child has had a long leg (hip to ankle) synthetic cast applied 4 hours ago. Which statement from the mother indicates that teaching has been inadequate?

• A. I will keep the cast covered the next day to prevent skin burning.
• B. I can apply an ice pack over the area to relieve itching inside the cast.
• C. The cast should be propped on at least 2 pillows when my child is lying down.
• D. I think I remember that standing cannot be done until after 72 hours.

Correct answer: D

Rationale: The correct answer is D because there is no need to wait 72 hours before allowing the child to stand. The synthetic cast does not affect weight-bearing capacity, and standing can be done as tolerated. Choice A is incorrect because keeping the cast covered can lead to damage or accidents. Choice B is acceptable as applying an ice pack can help relieve itching. Choice C is also correct as elevating the cast on pillows can help reduce swelling and promote comfort during rest.

5. The healthcare provider is providing postoperative care to a client who had a submucosal resection (SMR) for a deviated septum. The healthcare provider should monitor for what complication associated with this type of surgery?

• A. Occipital headache
• B. Periorbital crepitus
• C. Expectoration of blood
• D. Changes in vocalization

Correct answer: C

Rationale: Expectoration of blood is a potential complication following SMR surgery, as it may indicate bleeding postoperatively. In contrast, occipital headache (choice A) is not a common complication associated with SMR surgery. Periorbital crepitus (choice B) is more related to facial fractures or certain infections rather than SMR surgery. Changes in vocalization (choice D) are not typically associated with complications following SMR surgery.
