Nursing Elites

1. The healthcare provider prescribes furosemide (Lasix) 15 mg IV stat. On hand is Lasix 20 mg/2 ml. How many milliliters should the LPN/LVN administer?

• A. 1 ml.
• B. 1.5 ml.
• C. 1.75 ml.
• D. 2 ml.

Correct answer: B

Rationale: To calculate the correct dose of 15 mg, the LPN/LVN should administer 1.5 ml of Lasix (20 mg/2 ml). This calculation ensures precise dosing. Choice A (1 ml) is too low and would provide only 10 mg, while choice C (1.75 ml) and choice D (2 ml) would exceed the prescribed dose, resulting in potential adverse effects. It is important for the LPN/LVN to administer the exact prescribed dose to ensure therapeutic efficacy and avoid unnecessary complications.

2. The healthcare provider is reviewing the plan of care for a client with a newly placed colostomy. Which outcome would indicate effective client teaching?

• A. Client demonstrates how to irrigate the colostomy.
• B. Client verbalizes understanding of dietary changes.
• C. Client performs ostomy care independently.
• D. Client expresses feelings about the impact of the colostomy.

Correct answer: C

Rationale: The correct answer is C because effective teaching is demonstrated when the client can independently perform ostomy care. This indicates that the client has understood and retained the information provided during teaching. Choices A, B, and D are incorrect because demonstrating how to irrigate the colostomy, verbalizing understanding of dietary changes, and expressing feelings about the impact of the colostomy are important aspects of care but do not directly reflect the client's ability to apply the taught information in a practical setting.

3. A healthcare provider is preparing to insert an IV catheter into a client's arm before starting IV fluid therapy. Which of the following interventions should the provider implement to prevent infection?

• A. Thread the IV catheter so that the hub rests at the insertion site
• B. Shave excess hair from around the insertion site
• C. Cleanse the site with hydrogen peroxide before IV catheter insertion
• D. Palpate the site carefully just before inserting the IV catheter

Correct answer: A

Rationale: Inserting the IV catheter so that the hub rests at the insertion site reduces the risk of contamination along the length of the catheter. This technique helps prevent introducing microbes into the bloodstream during the catheter insertion process. Shaving excess hair is unnecessary and can increase the risk of skin irritation and infection. Cleansing the site with hydrogen peroxide is outdated as it can cause tissue damage and delay wound healing. Palpating the site just before insertion can introduce bacteria from the skin surface into the insertion site, increasing the risk of infection.

4. When administering an otic medication to an older adult client, which action should the nurse take to ensure that the medication reaches the inner ear?

• A. Press gently on the tragus of the client's ear
• B. Pack a small piece of cotton deep into the client's ear canal
• C. Move the client's auricle down and back toward their head
• D. Tilt the client's head backward for 5 minutes

Correct answer: A

Rationale: The correct action to ensure that otic medication reaches the inner ear is to press gently on the tragus. The tragus is a small cartilaginous projection in front of the ear canal. Pressing on it helps to straighten the ear canal, allowing the medication to reach the inner ear. Packing cotton or moving the auricle can obstruct the ear canal and prevent proper medication delivery. Tilting the client's head backward is not necessary and may not facilitate the medication reaching the inner ear as effectively as pressing on the tragus.

5. When assessing a client’s heart sounds, the nurse hears a scratching sound during both systole and diastole. These sounds become more distinct when the nurse has the client sit up and lean forward. The nurse should document the presence of a:

• A. Pericardial friction rub
• B. Heart murmur
• C. S3 heart sound
• D. S4 heart sound

Correct answer: A

Rationale: A pericardial friction rub is characterized by a scratching sound that occurs during both systole and diastole. It becomes more distinct when the client is sitting up and leaning forward. This indicates an inflammation of the pericardial sac rubbing against the layers of the heart. Heart murmurs (choice B) are abnormal heart sounds caused by turbulent blood flow, not by friction like in a pericardial rub. S3 and S4 heart sounds (choices C and D) are additional heart sounds related to abnormal ventricular filling, not to pericardial friction rubs.
