Nursing Elites

1. A nurse is preparing to administer enoxaparin subcutaneously. Which of the following actions should the nurse take?

• A. Administer the medication with the needle at a 45-degree angle.
• B. Administer the medication with the needle at a 90-degree angle.
• C. Administer the medication with the needle at a 30-degree angle.
• D. Administer the medication with the needle at a 15-degree angle.

Correct answer: B

Rationale: Enoxaparin should be administered with the needle at a 90-degree angle to ensure proper subcutaneous delivery. Choice B is correct as it aligns with the recommended angle for subcutaneous injections. Administering enoxaparin at a 45-degree angle (Choice A), 30-degree angle (Choice C), or 15-degree angle (Choice D) would not be appropriate and may lead to improper administration or absorption of the medication.

2. A healthcare professional is preparing to administer dextrose 5% in water (D5W) 1,000-mL IV to infuse over 10 hr. How many mL/hr should the IV infusion pump be set to deliver? (Round the answer to the nearest whole number. Do not use a trailing zero.)

• A. 100 mL/hr
• B. 150 mL/hr
• C. 75 mL/hr
• D. 50 mL/hr

Correct answer: A

Rationale: To infuse 1,000 mL over 10 hr, the IV pump should be set to deliver 100 mL/hr. This calculation is derived by dividing the total volume (1,000 mL) by the total time in hours (10 hr), resulting in the infusion rate of 100 mL/hr. Choices B, C, and D are incorrect as they do not accurately reflect the correct calculation for this scenario.

3. A nurse is preparing to provide tracheostomy care for a client. Which of the following actions should the nurse take first?

• A. Perform hand hygiene
• B. Identify the client using two identifiers
• C. Prepare the sterile field
• D. Don sterile gloves

Correct answer: A

Rationale: Performing hand hygiene is essential before any direct patient care procedure to prevent the spread of infection. Proper hand hygiene helps reduce the risk of introducing harmful microorganisms to the client, especially when dealing with a procedure like tracheostomy care. Identifying the client, preparing the sterile field, and donning sterile gloves are all important steps in tracheostomy care, but hand hygiene precedes them to maintain asepsis and ensure patient safety.

4. The caregiver is teaching parents about the diet for a 4-month-old infant with gastroenteritis and mild dehydration. In addition to oral rehydration fluids, the diet should include

• A. Formula or breast milk
• B. Broth and tea
• C. Rice cereal and apple juice
• D. Gelatin and ginger ale

Correct answer: A

Rationale: The correct answer is A: Formula or breast milk. In infants with gastroenteritis and mild dehydration, it is essential to continue feeding them with formula or breast milk along with oral rehydration fluids to provide adequate nutrition and maintain hydration. Option B, broth and tea, may not provide the necessary nutrients and electrolytes needed for the infant's recovery. Option C, rice cereal and apple juice, can be harsh on the digestive system and may exacerbate diarrhea. Option D, gelatin and ginger ale, do not provide the necessary nutrients and can worsen the condition due to the high sugar content in ginger ale.

5. When assessing a male client, the nurse finds that he is fatigued and is experiencing muscle weakness, leg cramps, and cardiac dysrhythmias. Based on these findings, the nurse plans to check the client's laboratory values to validate the existence of which condition?

• A. Hyperphosphatemia
• B. Hypocalcemia
• C. Hypermagnesemia
• D. Hypokalemia

Correct answer: D

Rationale: The symptoms of muscle weakness, leg cramps, and cardiac dysrhythmias are indicative of hypokalemia, a condition characterized by low potassium levels. Checking the client's laboratory values for potassium will help confirm this diagnosis. Hyperphosphatemia (Choice A) is an elevated phosphate level in the blood, which is not consistent with the symptoms described. Hypocalcemia (Choice B) is a low calcium level and typically presents with different symptoms than those mentioned in the scenario. Hypermagnesemia (Choice C) is an excess of magnesium in the blood and does not align with the symptoms of muscle weakness, leg cramps, and cardiac dysrhythmias observed in the client.
