Nursing Elites

1. A nurse is preparing an infusion for a client who was hospitalized with deep-vein thrombosis. The orders read: 25,000 units of heparin in 250 mL of 0.9% sodium chloride to infuse at 800 units/hr. At what rate should the nurse set the infusion pump?

• A. 8 mL/hr
• B. 10 mL/hr
• C. 12 mL/hr
• D. 15 mL/hr

Correct answer: A

Rationale: To calculate the infusion rate, use the formula: (Desired units/hr / Total units) × Volume. In this case, it would be (800 units/hr / 25,000 units) × 250 mL = 8 mL/hr. Therefore, the nurse should set the infusion pump at 8 mL/hr. Choice B, 10 mL/hr, is incorrect because it does not match the calculated rate. Choices C and D, 12 mL/hr and 15 mL/hr respectively, are also incorrect as they do not align with the correct calculation based on the provided data.

2. A healthcare professional is preparing to administer metoprolol 200 mg PO daily. The medication available is metoprolol 100 mg/tablet. How many tablets should the healthcare professional administer? (Round the answer to the nearest whole number. Do not use a trailing zero.)

• A. 1 tablet
• B. 2 tablets
• C. 0.5 tablet
• D. 4 tablets

Correct answer: B

Rationale: To administer 200 mg of metoprolol using 100 mg tablets, the healthcare professional should give 2 tablets. Each tablet contains 100 mg of metoprolol, so 2 tablets will provide the required 200 mg dose. Choice A is incorrect because 1 tablet would only provide 100 mg, which is insufficient. Choice C is incorrect as fractions of tablets are usually not used in practice to ensure accurate dosing. Choice D is incorrect as it would result in an overdose, providing 400 mg instead of the prescribed 200 mg.

3. A client is being treated for paranoid schizophrenia. When the client became loud and boisterous, the nurse immediately placed him in seclusion as a precautionary measure. The client willingly complied. The nurse's action:

• A. May result in charges of unlawful seclusion and restraint
• B. Leaves the nurse vulnerable to charges of assault and battery
• C. Was appropriate given the client's history of violence
• D. Was necessary to maintain the therapeutic milieu of the unit

Correct answer: A

Rationale: Placing a client in seclusion without proper justification and documentation can lead to charges of unlawful seclusion and restraint, regardless of the client's compliance. This legal issue arises from the potential violation of the client's rights and must be avoided. Choice B is incorrect as the situation does not involve assault and battery. Choice C is incorrect as past violence alone does not justify seclusion without immediate risk. Choice D is incorrect as seclusion should be used based on individual risk and necessity, not solely for maintaining the therapeutic milieu.

4. A client is to receive cimetidine (Tagamet) 300 mg q6h IVP. The preparation arrives from the pharmacy diluted in 50 ml of 0.9% NaCl. The LPN plans to administer the IVPB dose over 20 minutes. For how many ml/hr should the infusion pump be set to deliver the secondary infusion?

• A. 150
• B. 50
• C. 100
• D. 75

Correct answer: A

Rationale: Setting the infusion pump to 150 ml/hr ensures the correct administration rate of the IVPB dose over 20 minutes. To calculate the infusion rate, consider that the total volume to be infused is 50 ml over 20 minutes. To convert this to ml/hr, the calculation is (50 ml / 20 minutes) x 60 minutes/hr = 150 ml/hr. Choices B, C, and D are incorrect as they do not reflect the correct calculation for the infusion rate needed to deliver the secondary infusion over the specified time.

5. A nurse in a provider's office is collecting information from an older adult who reports that he has been taking acetaminophen 500 mg/day for severe joint pain. The nurse should instruct the client that large doses of acetaminophen could cause which of the following adverse effects?

• A. Liver damage
• B. Renal failure
• C. Gastric bleeding
• D. Heart attack

Correct answer: A

Rationale: Correct Answer: Large doses of acetaminophen can cause liver damage, which is a known adverse effect of the medication. Acetaminophen is metabolized in the liver, and excessive amounts can overwhelm the liver's ability to process it, leading to hepatotoxicity. Renal failure (Choice B) is not typically associated with acetaminophen use. Gastric bleeding (Choice C) is more commonly linked to nonsteroidal anti-inflammatory drugs (NSAIDs) rather than acetaminophen. Heart attack (Choice D) is not a recognized adverse effect of acetaminophen, which primarily affects the liver when taken in large amounts.
