Nursing Elites

1. Which of the following solutions is routinely used to flush an IV device before and after the administration of blood to a client?

• A. 0.9% sodium chloride
• B. 5% dextrose in water solution
• C. Sterile water
• D. Heparin sodium

Correct answer: A

Rationale: The correct answer is 0.9% sodium chloride. Normal saline is 0.9% sodium chloride, which has the same osmolarity as blood and does not cause cell lysis. Choices 2 and 3, 5% dextrose in water solution and sterile water, are hypotonic solutions that can lead to cell lysis. Choice 4, Heparin sodium, is an anticoagulant and is not routinely used to flush an IV device before and after the administration of blood.

2. What can the nurse instruct the mother of a teething 9-month-old infant to relieve discomfort?

• A. Rub the infant's gums with baby aspirin dissolved in water.
• B. Obtain an over-the-counter (OTC) topical medication for gum pain relief.
• C. Schedule an appointment with a dentist for a dental evaluation.
• D. Give the infant cool liquids or a Popsicle and hard foods such as dry toast.

Correct answer: D

Rationale: Teething in infants can cause discomfort, but it is a normal process. Symptoms may include nighttime awakening, daytime restlessness, excess drooling, and temporary loss of appetite. The recommended approach to relieve teething discomfort includes providing cool liquids, a Popsicle, or hard foods like dry toast for chewing. These items can help soothe the infant's gums. Rubbing the gums with baby aspirin dissolved in water is not recommended as it can be harmful. OTC topical medications are unnecessary for teething discomfort. Scheduling a dental evaluation is not required solely for teething. It's important to avoid home remedies like baby aspirin and opt for safer options like cool liquids. If necessary, acetaminophen (Tylenol) can be used under healthcare provider guidance to alleviate discomfort.

3. A 25-year-old male is brought to the emergency room with a piece of metal in his eye. Which action by the nurse is correct?

• A. Use a magnet to remove the object.
• B. Rinse the eye thoroughly with saline.
• C. Cover both eyes with paper cups.
• D. Administer eye drops immediately.

Correct answer: C

Rationale: Covering both eyes with paper cups is the correct action as it helps prevent consensual movement of the affected eye. Attempting to remove the object with a magnet might cause trauma, making choice A incorrect. While rinsing the eye with saline may be necessary, it should be ordered by a doctor and is not the initial action for the nurse, making choice B incorrect. Administering eye drops immediately, as in choice D, is not appropriate in this scenario and does not address the primary concern of preventing further damage by limiting eye movement.

4. Some drugs are excreted into bile and delivered to the intestines. Prior to elimination from the body, the drug might be absorbed. This process is known as:

• A. hepatic clearance.
• B. total clearance.
• C. enterohepatic cycling.
• D. first-pass effect.

Correct answer: C

Rationale: The correct answer is 'enterohepatic cycling.' This process involves drugs being excreted into bile, delivered to the intestines, reabsorbed into the circulation, and can prolong the drug's presence in the body. 'Hepatic clearance' (Choice A) refers to the amount of drug eliminated by the liver. 'Total clearance' (Choice B) is the sum of all types of clearance including renal, hepatic, and respiratory. 'First-pass effect' (Choice D) is the amount of drug absorbed from the GI tract and metabolized by the liver before entering circulation, reducing the amount of drug available for systemic circulation.

5. How should Lasix be administered to prevent hypotension?

• A. By administering it over 1-2 minutes
• B. By hanging it IV piggyback
• C. With normal saline only
• D. By administering it through a venous access device

Correct answer: A

Rationale: Lasix should be administered over 1-2 minutes at approximately 1mL per minute to prevent hypotension. This slow administration helps to reduce the risk of adverse effects such as sudden drops in blood pressure. Choice B is incorrect because Lasix does not need to be hung IV piggyback, choice C is incorrect as Lasix administration does not require it to be mixed with normal saline only, and choice D is incorrect as Lasix does not have to be specifically administered through a venous access device (VAD) to prevent hypotension.
