Nursing Elites

1. A client asks a nurse about their Snellen eye test results. The client's visual acuity is 20/30. Which of the following responses should the nurse make?

• A. “Your eyes see at 20 feet what visually unimpaired eyes see at 30 feet.”
• B. “Your right eye can see the chart clearly at 20 feet, and your left eye can see the chart clearly at 30 feet.”
• C. “Your eyes see at 30 feet what visually unimpaired eyes see at 20 feet.”
• D. “Your left eye can see the chart clearly at 20 feet, and your right eye can see the chart clearly at 30 feet.”

Correct answer: A

Rationale: The correct answer is A: 'Your eyes see at 20 feet what visually unimpaired eyes see at 30 feet.' In the Snellen eye test, a visual acuity of 20/30 means that the client sees at 20 feet what a person with normal vision sees at 30 feet. This indicates that the client's vision is slightly worse than average. Choice B is incorrect as it incorrectly describes the visual acuity of each eye individually, rather than the combined visual acuity. Choice C is incorrect as it misinterprets the meaning of the Snellen eye test results by reversing the values. Choice D is incorrect as it inaccurately describes the visual acuity of the client's eyes, attributing different visual acuities to each eye instead of a combined measurement as indicated by 20/30.

2. The healthcare provider prescribes morphine sulfate 4mg IM STAT. Morphine comes in 8 mg per ml. How many ml should the LPN/LVN administer?

• A. 0.5 ml
• B. 1 ml
• C. 1.5 ml
• D. 2 ml

Correct answer: A

Rationale: To administer 4 mg of morphine, as prescribed, the LPN/LVN needs to calculate the correct volume based on the concentration provided (8 mg per ml). Since the desired dose is 4 mg, half of 8 mg (0.5 ml) is required to administer the correct amount. Therefore, the correct answer is 0.5 ml. Choices B, C, and D are incorrect as they would either underdose or overdose the patient.

3. A client with an NG tube is receiving intermittent feedings through an open system. Which of the following actions should the nurse take first?

• A. Rinse the feeding bag with water between feedings
• B. Tell the client to keep the head of the bed elevated at least 30°
• C. Make sure the enteral formula is at room temperature
• D. Wipe the top of the formula can with alcohol

Correct answer: B

Rationale: The correct answer is to tell the client to keep the head of the bed elevated at least 30°. Elevating the head of the bed prevents aspiration of the enteral formula, which is a priority in caring for a client with an NG tube. This action helps in reducing the risk of complications such as pneumonia. Choices A, C, and D are incorrect. While rinsing the feeding bag, ensuring the enteral formula temperature, and maintaining cleanliness are important aspects of enteral feeding care, the priority is to prevent aspiration by keeping the head of the bed elevated. These actions can be implemented after ensuring the client's safety by maintaining the correct bed position.

4. To ensure the safety of a client receiving a continuous intravenous normal saline infusion, how often should the LPN change the administration set?

• A. Every 4 to 8 hours
• B. Every 12 to 24 hours
• C. Every 24 to 48 hours
• D. Every 72 to 96 hours

Correct answer: D

Rationale: The correct answer is to change the administration set every 72 to 96 hours. This practice helps reduce the risk of infection by preventing the build-up of bacteria in the tubing. Changing the set too frequently (choices A, B, and C) may increase the chances of contamination and infection without providing additional benefits. Therefore, the LPN should follow the guideline of changing the administration set every 72 to 96 hours to maintain the client's safety during the continuous intravenous normal saline infusion.

5. The nurse is preparing to administer a subcutaneous injection of enoxaparin (Lovenox). Which site is most appropriate for the LPN/LVN to use?

• A. Deltoid muscle
• B. Ventrogluteal site
• C. Abdomen
• D. Dorsogluteal site

Correct answer: C

Rationale: The abdomen is the most appropriate site for administering subcutaneous injections of enoxaparin (Lovenox). Enoxaparin is typically administered in the abdomen due to better absorption and reduced risk of injury to underlying structures. The deltoid muscle is not recommended for subcutaneous injections of enoxaparin due to the potential risk of injury to underlying structures. The ventrogluteal and dorsogluteal sites are more appropriate for intramuscular injections rather than subcutaneous injections.
