Nursing Elites

1. Prior to a cardiac catheterization, what instruction should the client be reminded of?

• A. You will need to be NPO for 6 to 8 hours before the procedure.
• B. You will not be able to move around during the procedure.
• C. You will be required to lie still for several hours after the test.
• D. You will not have to drink any fluids immediately before the test.

Correct answer: A

Rationale: Being NPO (nothing by mouth) for 6 to 8 hours before a cardiac catheterization is crucial to prevent complications such as aspiration during the procedure. This helps ensure the safety and accuracy of the test results by minimizing the risk of food or liquid in the stomach interfering with the procedure. Choice B is incorrect because the client will need to lie still during the procedure to ensure its accuracy. Choice C is incorrect as the client is typically required to lie flat for a few hours after the test, not several hours. Choice D is incorrect as the client is usually not allowed to drink fluids immediately before the test to prevent complications.

2. When assessing a client receiving total parenteral nutrition (TPN), which laboratory value is most important for the nurse to monitor regularly?

• A. Albumin
• B. Calcium
• C. Glucose
• D. Alkaline phosphatase

Correct answer: C

Rationale: The most important laboratory value to monitor regularly in clients receiving total parenteral nutrition (TPN) is glucose. TPN solutions contain high concentrations of glucose, which can lead to hyperglycemia. Monitoring glucose levels is crucial to detect and prevent hyperglycemia, a common complication associated with TPN administration. Albumin (Choice A) levels are not typically affected by TPN administration. Calcium (Choice B) and alkaline phosphatase (Choice D) are not directly impacted by TPN and are not the primary values to monitor in TPN therapy.

3. The client is receiving furosemide (Lasix) for heart failure. What potential side effect should the nurse monitor for?

• A. Hypokalemia
• B. Hyperkalemia
• C. Hypernatremia
• D. Hypoglycemia

Correct answer: A

Rationale: The correct answer is A: Hypokalemia. Furosemide, a loop diuretic, causes potassium loss, leading to hypokalemia. Monitoring potassium levels is crucial because hypokalemia can result in cardiac arrhythmias and muscle weakness. Choices B, C, and D are incorrect because furosemide does not typically cause hyperkalemia, hypernatremia, or hypoglycemia.

4. A client with a diagnosis of angina pectoris is prescribed nitroglycerin tablets. How should the nurse instruct the client to take the medication?

• A. Swallow the tablet whole with water
• B. Place the tablet under the tongue and let it dissolve
• C. Chew the tablet and then swallow
• D. Place the tablet between the cheek and gum

Correct answer: B

Rationale: Nitroglycerin is most effective when administered sublingually (under the tongue) as it is rapidly absorbed into the bloodstream. Placing the tablet under the tongue allows for quick absorption and faster relief of angina symptoms. Chewing the tablet, swallowing it, or placing it between the cheek and gum would not provide the same rapid onset of action needed during an angina episode. Therefore, the correct instruction for the client is to place the nitroglycerin tablet under the tongue and let it dissolve for optimal effectiveness.

5. The LPN/LVN is assisting in the care of a client with chronic heart failure who is receiving digoxin (Lanoxin). Which sign should the nurse monitor for that could indicate digoxin toxicity?

• A. Bradycardia
• B. Tachycardia
• C. Hypertension
• D. Hyperglycemia

Correct answer: A

Rationale: Bradycardia is a common sign of digoxin toxicity and should be closely monitored. Digoxin toxicity can lead to various cardiac dysrhythmias, with bradycardia being a significant indicator. Monitoring the client's heart rate is crucial to detect and manage digoxin toxicity promptly. Tachycardia, hypertension, and hyperglycemia are not typically associated with digoxin toxicity. Tachycardia is more commonly seen with inadequate treatment of heart failure, hypertension is a possible but less common effect, and hyperglycemia is not a typical sign of digoxin toxicity.
