Nursing Elites

1. A nurse reviews the electrolyte results of an assigned client and notes that the potassium level is 5.4 mEq/L. Which of the following would the nurse expect to note on the electrocardiogram as a result of the laboratory value?

• A. ST depression
• B. Inverted T wave
• C. Prominent U wave
• D. Tall peaked T waves

Correct answer: D

Rationale: The correct answer is 'Tall peaked T waves.' Tall peaked T waves are characteristic ECG changes associated with hyperkalemia. In hyperkalemia, the elevated potassium levels affect the myocardium, leading to changes in the ECG. ST depression (Choice A) is more commonly associated with myocardial ischemia or infarction. Inverted T wave (Choice B) is seen in conditions like myocardial ischemia or CNS events. Prominent U wave (Choice C) is typically associated with hypokalemia or certain medications. Therefore, in this scenario, the nurse would expect to note tall peaked T waves on the electrocardiogram due to the elevated potassium level.

2. A nurse is assessing a client with a suspected diagnosis of hypocalcemia. Which of the following clinical manifestations would the nurse expect to note in the client?

• A. Twitching
• B. Positive Trousseau's sign
• C. Hyperactive bowel sounds
• D. Hyperactive deep tendon reflexes

Correct answer: A

Rationale: The correct answer is A: Twitching. Hypocalcemia often presents with neuromuscular irritability, leading to manifestations such as twitching. Trousseau's sign is actually a positive indicator of hypocalcemia, not negative, making choice B incorrect. Hypoactive bowel sounds are not typically associated with hypocalcemia, making choice C incorrect. Similarly, hypoactive deep tendon reflexes are not a common finding in hypocalcemia, making choice D incorrect.

3. A patient's serum potassium level is 2.2 mEq/L. Which nursing action is the highest priority for this patient?

• A. Start oxygen at 2 L/min
• B. Initiate cardiac monitoring
• C. Initiate seizure precautions
• D. Keep the patient on bed rest

Correct answer: B

Rationale: The correct answer is to initiate cardiac monitoring. Severe hypokalemia can lead to life-threatening arrhythmias, making cardiac monitoring the priority to detect and manage any cardiac complications. Starting oxygen, seizure precautions, or bed rest are not the immediate priority actions for severe hypokalemia.

4. Select the type of skeletal fracture that is correctly paired with its description.

• A. A complete fracture: The fractured bone penetrates through the skin to the skin surface.
• B. A pathological fracture: A fracture that results from some physical trauma.
• C. A greenstick fracture: This bends but does not fracture the bone.
• D. An avulsion fracture: A fracture that pulls a part of the bone from the tendon or ligament

Correct answer: D

Rationale: The correct answer is D. An avulsion fracture occurs when a part of the bone is pulled away by a tendon or ligament. Choice A is incorrect because it describes an open fracture where the bone penetrates the skin. Choice B is incorrect as a pathological fracture results from an underlying disease weakening the bone, not physical trauma. Choice C is incorrect as a greenstick fracture involves the bone bending but not completely breaking.

5. Which of the following is a common barrier to effective communication in healthcare?

• A. Active listening
• B. Cultural differences
• C. Clear language
• D. Empathy

Correct answer: B

Rationale: Cultural differences are a common barrier to effective communication in healthcare. When individuals from different cultures interact in healthcare settings, varying communication styles, beliefs, values, and language barriers can hinder effective communication. This can lead to misunderstandings, misinterpretations, and ultimately impact the quality of care provided. Active listening (choice A) is a communication skill that helps improve understanding and can actually enhance communication. Clear language (choice C) is essential for effective communication and can help overcome barriers, rather than being a barrier itself. Empathy (choice D) is important in healthcare to understand patients' emotions and perspectives, but it is not a common barrier to effective communication.
