1. The nurse is preparing to administer a subcutaneous injection of insulin to a client with diabetes. What is the best site for the nurse to select for this injection?
- A. Ventrogluteal site
- B. Dorsogluteal site
- C. Deltoid site
- D. Abdomen
Correct answer: D
Rationale: The correct answer is 'D: Abdomen.' The abdomen is the best site for insulin injections as it provides a larger area with consistent absorption rates due to the high vascularity of the area. The subcutaneous tissue in the abdomen allows for a more predictable and consistent absorption of insulin compared to other sites. Ventrogluteal and dorsogluteal sites are not commonly used for insulin injections due to the risk of hitting the sciatic nerve or causing tissue damage. The deltoid site is more commonly used for intramuscular injections rather than subcutaneous injections like insulin.
2. A nurse is preparing an infusion for a client who was hospitalized with deep-vein thrombosis. The orders read: 25,000 units of heparin in 250 mL of 0.9% sodium chloride to infuse at 800 units/hr. At what rate should the nurse set the infusion pump?
- A. 8 mL/hr
- B. 10 mL/hr
- C. 12 mL/hr
- D. 15 mL/hr
Correct answer: A
Rationale: To calculate the infusion rate, use the formula: (Desired units/hr / Total units) × Volume. In this case, it would be (800 units/hr / 25,000 units) × 250 mL = 8 mL/hr. Therefore, the nurse should set the infusion pump at 8 mL/hr. Choice B, 10 mL/hr, is incorrect because it does not match the calculated rate. Choices C and D, 12 mL/hr and 15 mL/hr respectively, are also incorrect as they do not align with the correct calculation based on the provided data.
3. A client has acute renal failure. Which of the following assessments provides the most accurate measure of the client's fluid status?
- A. Daily weight
- B. Intake and output
- C. Urine specific gravity
- D. Peripheral edema
Correct answer: A
Rationale: Daily weight is the most accurate measure of fluid status in a client with acute renal failure. Fluctuations in weight reflect changes in body fluid volume, including both fluid retention or loss. Intake and output, while important, may not always accurately reflect overall fluid status as it does not account for insensible losses. Urine specific gravity can provide information on urine concentration but does not offer a comprehensive assessment of overall fluid status. Peripheral edema, although a sign of fluid retention, is a more subjective assessment and may not always accurately reflect the client's fluid status like daily weight monitoring does.
4. The healthcare provider is monitoring a client in active labor. Which pattern on the fetal heart monitor requires immediate intervention?
- A. Early decelerations
- B. Late decelerations
- C. Accelerations
- D. Moderate variability
Correct answer: B
Rationale: Late decelerations are concerning as they indicate uteroplacental insufficiency, potentially resulting in fetal hypoxia. Immediate intervention is necessary to address the underlying cause and ensure fetal well-being. Early decelerations are typically benign and associated with head compression during contractions. Accelerations are reassuring and indicate fetal well-being. Moderate variability is a normal finding and indicates a healthy autonomic nervous system response. Therefore, late decelerations (Choice B) require immediate attention, while the other patterns are generally considered normal or benign during labor.
5. A nurse is inserting an IV catheter for a client that results in a blood spill on her gloved hand. The client has no documented bloodstream infection. Which of the following actions should the nurse take?
- A. Carefully remove the gloves and follow with hand hygiene
- B. Continue with the procedure and clean hands later
- C. Remove the gloves, wash hands, and start over
- D. Use hand sanitizer and continue the procedure
Correct answer: A
Rationale: The correct action for the nurse to take in this situation is to carefully remove the gloves and follow with hand hygiene. This is important to prevent potential contamination and maintain infection control practices. Option B is incorrect because cleaning hands later may lead to the spread of potential contaminants. Option C is unnecessary as starting over is not required if proper hand hygiene is performed. Option D is not sufficient in ensuring proper hygiene after a blood spill, as hand sanitizer may not effectively remove all contaminants.
