Nursing Elites

1. A nurse is preparing to insert an IV catheter for a client. Which of the following actions should the nurse take?

• A. Apply a tourniquet above the insertion site
• B. Shave the area around the insertion site
• C. Insert the catheter at a 15-degree angle
• D. Use an 18-gauge needle for insertion

Correct answer: C

Rationale: The correct answer is to insert the catheter at a 15-degree angle. This angle allows for easier venous access by ensuring proper catheter placement into the vein. Applying a tourniquet above the insertion site can help distend the vein for better visualization but is not the immediate action required for the insertion process. Shaving the area around the insertion site is not necessary unless there is excessive hair that may interfere with the insertion. Using an 18-gauge needle for insertion is a specific detail related to the equipment rather than the technique of insertion.

2. A nurse is providing teaching to a client who has been prescribed digoxin for heart failure. Which of the following instructions should the nurse include?

• A. Take this medication with meals.
• B. Check your pulse before taking this medication.
• C. Take this medication with an antacid to reduce stomach upset.
• D. Increase your potassium intake while taking this medication.

Correct answer: B

Rationale: The correct answer is B: 'Check your pulse before taking this medication.' When a patient is prescribed digoxin, it is crucial to monitor their pulse rate because digoxin can cause bradycardia (slow heart rate) as a side effect. In contrast, choices A, C, and D are incorrect. Taking digoxin with meals is not necessary; it should be taken consistently at the same time every day. Taking digoxin with an antacid is not recommended as it can interfere with the absorption of the medication. While digoxin can cause hypokalemia (low potassium levels), patients should not increase their potassium intake without healthcare provider guidance to avoid potential complications.

3. A nurse is reviewing the results of an arterial blood gas analysis of a client who has chronic obstructive pulmonary disease. Which of the following results should the nurse expect?

• A. PaO2 of 95 mm Hg
• B. PaCO2 of 55 mm Hg
• C. HCO3 of 24 mEq/L
• D. pH level of 7.35

Correct answer: B

Rationale: In chronic obstructive pulmonary disease, there is impaired gas exchange, leading to retention of carbon dioxide (CO2) and subsequent respiratory acidosis. A PaCO2 of 55 mm Hg is higher than the normal range (35-45 mm Hg) and is indicative of respiratory acidosis in COPD. Choices A, C, and D are not typically associated with COPD. PaO2 may be decreased, HCO3 may be elevated to compensate for acidosis, and pH may be lower than 7.35 due to respiratory acidosis in COPD.

4. A nurse is preparing to administer a dose of vancomycin IV to a client who has a methicillin-resistant Staphylococcus aureus (MRSA) infection. Which of the following actions should the nurse take?

• A. Administer the medication over 15 minutes.
• B. Monitor the client's urine output every 8 hours.
• C. Check the client's creatinine level before administering the medication.
• D. Assess the client for a history of allergies to antibiotics.

Correct answer: C

Rationale: The correct action for the nurse to take is to check the client's creatinine level before administering vancomycin. Vancomycin is known to be nephrotoxic, so assessing the client's renal function before administering the medication is crucial to prevent further kidney damage. Administering the medication over 15 minutes (Choice A) is not the priority in this scenario as renal function assessment takes precedence. Monitoring urine output (Choice B) is important for assessing renal function but checking creatinine level directly provides more accurate information. Assessing for allergies to antibiotics (Choice D) is also important but not as essential as checking the creatinine level due to the nephrotoxic nature of vancomycin.

5. How should a healthcare professional administer a subcutaneous injection?

• A. Insert the needle at a 45-degree angle
• B. Insert the needle at a 90-degree angle
• C. Use a Z-track method
• D. Insert the needle at a 15-degree angle

Correct answer: A

Rationale: The correct technique for administering subcutaneous injections is to insert the needle at a 45-degree angle. This angle ensures that the medication is delivered into the subcutaneous tissue, which is located just below the skin. Inserting the needle at a 90-degree angle is more appropriate for intramuscular injections, while using a Z-track method is specific to intramuscular injections to prevent leakage of medication into the subcutaneous tissue. Inserting the needle at a 15-degree angle would not reach the subcutaneous tissue effectively.
