Nursing Elites

1. A client's serum calcium level is 7.9 mg/dL. The nurse is immediately concerned, knowing that this level could lead to which complication?

• A. Stroke
• B. Cardiac arrest
• C. High blood pressure
• D. Urinary stone formation

Correct answer: B

Rationale: A serum calcium level below normal (hypocalcemia) can lead to cardiac arrhythmias and potentially cardiac arrest. Calcium plays a crucial role in cardiac muscle contractility, and low levels can disrupt normal heart function, potentially leading to fatal arrhythmias and cardiac arrest. Choices A, C, and D are incorrect as hypocalcemia is not directly associated with stroke, high blood pressure, or urinary stone formation. The immediate concern with low serum calcium levels is the risk of cardiac complications.

2. A client has a new prescription for phenytoin. Which of the following instructions should the nurse include?

• A. Take the medication with a full glass of water.
• B. Avoid consuming dairy products.
• C. Take the medication on an empty stomach.
• D. Expect a metallic taste in your mouth.

Correct answer: B

Rationale: The correct instruction for a client prescribed phenytoin is to avoid consuming dairy products. Dairy products can reduce the absorption of phenytoin. Taking the medication with a full glass of water (Choice A) is generally a good practice for oral medications but is not specifically required for phenytoin. Taking the medication on an empty stomach (Choice C) can lead to gastrointestinal upset, so it is not recommended for phenytoin. Expecting a metallic taste in the mouth (Choice D) is a possible side effect of phenytoin but is not a crucial instruction for the client to follow.

3. A client with a history of myocardial infarction (MI) is being discharged with a prescription for nitroglycerin sublingual tablets. Which instruction should the nurse reinforce?

• A. Store the tablets in a cool, dry place away from light.
• B. Take a tablet every 5 minutes if chest pain occurs.
• C. Place the tablets under the tongue for sublingual absorption.
• D. Take the tablets without water for faster effect.

Correct answer: A

Rationale: The correct answer is A. Nitroglycerin tablets are light and moisture-sensitive, so they should be stored in a cool, dry place away from light to maintain their effectiveness. Option B advises taking a tablet every 5 minutes, which may lead to overdose as this frequency is too high. Option C emphasizes the correct administration route for sublingual tablets. Option D is incorrect as water is not needed for the tablets to take effect.

4. After returning the client to bed following a cardiac catheterization procedure with the left femoral vessel as the access site, the nurse places a sign above the bed instructing the client to remain on bed rest and in which position?

• A. In semi-Fowler's position
• B. With the head of the bed elevated 45 degrees
• C. With the head of the bed elevated no more than 15 degrees
• D. With the foot of the bed elevated as much as tolerated by the client

Correct answer: C

Rationale: After cardiac catheterization via the femoral vessel, it is crucial to keep the head of the bed elevated no more than 15 degrees to prevent bleeding at the access site. This position helps maintain pressure on the femoral artery, reducing the risk of bleeding and complications post-procedure. Choices A, B, and D are incorrect because they do not provide the necessary pressure on the femoral artery to prevent bleeding, which is essential after a cardiac catheterization procedure with a femoral access site.

5. When preparing to administer medication to a client, what action should the nurse take first?

• A. Verify the client's identity.
• B. Check the medication expiration date.
• C. Review the client's medical history.
• D. Obtain the client's vital signs.

Correct answer: A

Rationale: Verifying the client's identity is the initial and most critical step in medication administration. It is crucial to confirm that the right medication is being given to the correct patient. Checking the client's identity helps prevent medication errors and ensures patient safety. Checking the medication expiration date (choice B) is important but should come after verifying the client's identity. Reviewing the client's medical history (choice C) is valuable but not the first step in medication administration. Obtaining the client's vital signs (choice D) is essential in some situations but is usually not the first action needed before administering medication.
