Nursing Elites

1. Based on this strip, what is the correct interpretation of this rhythm?

• A. Atrial fibrillation.
• B. Premature atrial fibrillation.
• C. AV block.
• D. Ventricular tachycardia.

Correct answer: A

Rationale: The correct interpretation of the rhythm strip is atrial fibrillation. This arrhythmia is characterized by an irregular heartbeat and the absence of distinct P waves. Choice B, premature atrial fibrillation, is incorrect as there is no indication of premature beats in the strip. Choice C, AV block, is also incorrect as there is no evidence of conduction delays between the atria and ventricles. Choice D, ventricular tachycardia, is not supported by the absence of wide QRS complexes typically seen in this arrhythmia.

2. The nurse is caring for a client with a nasogastric tube. Which action should the nurse take to ensure proper functioning of the tube?

• A. Flush the tube with 50 mL of normal saline every 8 hours
• B. Clamp the tube when not in use
• C. Position the client in a supine position
• D. Verify tube placement by checking pH of gastric contents

Correct answer: D

Rationale: Verifying tube placement by checking the pH of gastric contents is crucial to ensure the nasogastric tube is correctly positioned in the stomach. This action helps prevent complications such as aspiration. Flushing the tube with normal saline every 8 hours is not necessary for ensuring proper functioning of the tube. Clamping the tube when not in use may lead to the build-up of gastric secretions and blockages. Positioning the client in a supine position is not directly related to ensuring the proper functioning of the nasogastric tube.

3. A client with a history of hypertension is admitted with a blood pressure of 220/120 mm Hg. What is the priority nursing action?

• A. Administer antihypertensive medication as prescribed.
• B. Place the client in a supine position.
• C. Obtain a detailed health history.
• D. Monitor urine output.

Correct answer: A

Rationale: Administering antihypertensive medication is the priority nursing action in this situation. The extremely high blood pressure of 220/120 mm Hg puts the client at risk of severe complications such as stroke, heart attack, or kidney damage. Lowering the blood pressure promptly is crucial to prevent these complications. Placing the client in a supine position or obtaining a detailed health history are not immediate actions needed to address the hypertensive crisis. Monitoring urine output, although important, is not the priority when the client's blood pressure is critically high.

4. The nurse is reviewing blood pressure readings for a group of clients on a medical unit. Which client is at the highest risk for complications related to hypertension?

• A. Post-menopausal Caucasian female who overeats and is 20% above her ideal body weight.
• B. Young adult Hispanic female who has hemoglobin at 11 g/dl (110 g/L) and drinks beer daily.
• C. Older adult who consumes a diet of smoked, cured, and pickled foods.
• D. Middle-aged African-American male who has a serum creatinine level of 2.9 mg/dL (256.4 micromol/L).

Correct answer: D

Rationale: The correct answer is D. An elevated serum creatinine level indicates kidney damage, which significantly increases the risk of complications from hypertension. High blood pressure can damage the kidneys over time, leading to impaired kidney function. Choices A, B, and C do not directly correlate with increased risk of complications related to hypertension. Choice A focuses on obesity and overeating, Choice B on anemia and alcohol consumption, and Choice C on a diet high in sodium and nitrates, none of which are as directly related to hypertension complications as kidney damage.

5. A client with diabetes mellitus is experiencing polyuria, polydipsia, and polyphagia. What do these symptoms indicate?

• A. Hypoglycemia
• B. Diabetic ketoacidosis (DKA)
• C. Hyperosmolar hyperglycemic state (HHS)
• D. Insulin shock

Correct answer: B

Rationale: Polyuria, polydipsia, and polyphagia are classic signs of diabetic ketoacidosis (DKA), which occurs due to a combination of hyperglycemia and ketone production. Hypoglycemia (Choice A) is characterized by low blood sugar levels, leading to symptoms like confusion, shakiness, and sweating, which are different from the symptoms described in the scenario. Hyperosmolar hyperglycemic state (HHS) (Choice C) typically presents with severe hyperglycemia, dehydration, and altered mental status, rather than the triad of symptoms mentioned. Insulin shock (Choice D) refers to a severe hypoglycemic reaction due to excessive insulin, manifesting with confusion, sweating, and rapid heartbeat, not the symptoms seen in the client with diabetes mellitus described in this scenario.
