Nursing Elites

1. What are the expected changes on an ECG for a patient with hypokalemia?

• A. Flattened T waves
• B. Prominent U waves
• C. ST elevation
• D. Wide QRS complexes

Correct answer: A

Rationale: Flattened T waves are an early sign of hypokalemia on an ECG. Hypokalemia primarily manifests as flattened T waves on an ECG. While prominent U waves can be seen in hypokalemia, they are not as specific as flattened T waves. ST elevation is more commonly associated with conditions like myocardial infarction rather than hypokalemia. Wide QRS complexes are typically not a feature of hypokalemia on an ECG.

2. A patient is receiving discharge instructions for GERD. Which of the following statements by the patient demonstrates an understanding of the teaching?

• A. I should take my medication with orange juice.
• B. Having a bedtime snack will prevent heartburn.
• C. I will lie down after meals.
• D. I will limit activities that require bending at the waist.

Correct answer: D

Rationale: The correct answer is D. Patients with GERD should avoid activities that increase intra-abdominal pressure, such as bending at the waist, as this can lead to reflux. Choice A is incorrect because medications for GERD are usually taken with water, not citrus juices. Choice B is incorrect as having a bedtime snack can worsen GERD symptoms. Choice C is incorrect because lying down after meals can also exacerbate reflux due to the effects of gravity.

3. A patient has been diagnosed with a thrombotic stroke. What are the expected manifestations?

• A. Gradual loss of function on one side of the body
• B. Sudden loss of consciousness
• C. Seizures and confusion
• D. Loss of sensation in the affected limb

Correct answer: A

Rationale: The correct answer is A: 'Gradual loss of function on one side of the body.' Thrombotic strokes lead to slow and progressive symptoms as a result of decreased blood flow to a specific area of the brain. Choices B, C, and D are incorrect because sudden loss of consciousness, seizures, confusion, and loss of sensation in the affected limb are not typical manifestations of a thrombotic stroke.

4. A nurse is planning care for a group of postoperative clients. Which of the following interventions should the nurse identify as the priority?

• A. Administer IV pain medication to a client who reports pain as a 6 on a scale of 0 to 10
• B. Administer oxygen to a client who has an oxygen saturation of 91%
• C. Instruct a client who is 1 hr postoperative about coughing and deep breathing exercises
• D. Initiate an infusion of 0.9% sodium chloride for a client who has just had abdominal surgery

Correct answer: B

Rationale: The priority intervention is administering oxygen. Postoperatively, the client's oxygen saturation should be at or above 95%. Oxygen is essential for tissue perfusion and cellular oxygenation. While managing pain is important, oxygenation takes precedence. Instructing a client about coughing and deep breathing exercises is important for preventing respiratory complications but is not as urgent as addressing low oxygen saturation. Initiating an infusion of 0.9% sodium chloride is a routine postoperative intervention for fluid balance but is not the priority when oxygen saturation is low.

5. A nurse is admitting a client who has suspected appendicitis. Which of the following findings should the nurse report to the provider immediately?

• A. Distended, board-like abdomen
• B. WBC count of 15,000/mm3
• C. Rebound tenderness over McBurney's point
• D. Temperature of 37.3°C (99.1°F)

Correct answer: A

Rationale: A distended, board-like abdomen should be reported to the provider immediately because it indicates peritonitis, a serious complication of appendicitis resulting from a ruptured appendix. Option B, an elevated WBC count, may indicate infection but is not as urgent as a board-like abdomen. Option C, rebound tenderness over McBurney's point, is a classic sign of appendicitis but does not indicate immediate life-threatening complications. Option D, a slightly elevated temperature, is not as concerning as a distended, board-like abdomen.
