A nurse is preparing to administer a medication that requires a peak and trough level. What is the nurse's priority action?
- A. Administer the medication before the peak level is obtained.
- B. Withhold the medication until the trough level is obtained.
- C. Administer the medication based on the previous trough level.
- D. Ensure that the medication is administered within 2 hours of the peak level.
Correct Answer: B
Rationale: The nurse's priority action should be to withhold the medication until the trough level is obtained. This is crucial to ensure accurate dosing based on the patient's levels. Administering the medication before the peak level is obtained (choice A) can lead to incorrect dosing. Administering the medication based on the previous trough level (choice C) may not reflect the current levels accurately. Ensuring that the medication is administered within 2 hours of the peak level (choice D) is not necessary for obtaining accurate peak and trough levels.

A patient with a urinary tract infection (UTI) requires treatment. What is the most appropriate intervention?
- A. Encourage the patient to increase fluid intake.
- B. Administer antibiotics as prescribed.
- C. Recommend the patient take over-the-counter pain relievers.
- D. Encourage the patient to limit physical activity.
Correct Answer: B
Rationale: The correct answer is to administer antibiotics as prescribed. Antibiotics are the primary treatment for urinary tract infections as they help eliminate the bacteria causing the infection. Encouraging the patient to increase fluid intake (Choice A) is a supportive measure to help flush out the bacteria but doesn't directly treat the infection. Over-the-counter pain relievers (Choice C) may help with discomfort but do not address the underlying infection. Limiting physical activity (Choice D) may be recommended for some conditions but is not the primary intervention for treating a UTI.
A patient with severe pain and leg swelling is admitted. What should the nurse assess for?
- A. Check for signs of deep vein thrombosis.
- B. Assess for compartment syndrome.
- C. Increase the patient's fluid intake.
- D. Prepare the patient for surgery to relieve pain.
Correct Answer: B
Rationale: When a patient presents with severe pain and leg swelling, the nurse should assess for compartment syndrome. Compartment syndrome is a serious condition that can develop due to increased pressure within a muscle compartment, leading to compromised circulation and potential tissue damage. It is crucial to identify compartment syndrome promptly as it may require immediate intervention to prevent further complications. Checking for signs of deep vein thrombosis (Choice A) is also important in a patient with leg swelling, but in this scenario, the focus should be on assessing for compartment syndrome due to the severity of the symptoms. Increasing fluid intake (Choice C) may not address the underlying cause of the patient's symptoms. Preparing the patient for surgery (Choice D) without a comprehensive assessment and diagnosis is premature and may not be the appropriate initial intervention.
A patient is receiving enteral feedings through a nasogastric (NG) tube. What is the most appropriate nursing intervention?
- A. Flush the NG tube with water before and after each feeding.
- B. Check the placement of the NG tube before each feeding.
- C. Administer medications through the NG tube every 4 hours.
- D. Increase the feeding rate if the patient is tolerating well.
Correct Answer: B
Rationale: Checking the placement of the NG tube before each feeding is crucial as it ensures the tube is correctly positioned, reducing the risk of complications such as aspiration or improper delivery of feedings. Flushing the NG tube with water before and after each feeding can disrupt the feeding schedule and is not a standard procedure. Administering medications through the NG tube every 4 hours may not be necessary for all patients and should be based on specific medication requirements. Increasing the feeding rate without proper assessment and monitoring can lead to feeding intolerance or complications, making it an inappropriate intervention.
A patient with chronic obstructive pulmonary disease (COPD) is being cared for by a nurse. What is the most appropriate action to improve the patient's oxygenation?
- A. Encourage the patient to use incentive spirometry.
- B. Administer oxygen via nasal cannula as prescribed.
- C. Assist the patient with coughing and deep breathing exercises.
- D. Position the patient in a high Fowler's position.
Correct Answer: B
Rationale: Administering oxygen via nasal cannula as prescribed is the most appropriate action to improve the patient's oxygenation in COPD. Oxygen therapy helps maintain adequate oxygen levels in the blood, which is crucial for managing COPD. Encouraging the use of incentive spirometry, assisting with coughing and deep breathing exercises, and positioning the patient in high Fowler's position are all beneficial interventions, but administering oxygen is the priority for immediate oxygenation support in COPD.
A nurse is caring for a patient with an infection. Which laboratory result is most important to monitor?
- A. White blood cell count (WBC)
- B. C-reactive protein (CRP)
- C. Erythrocyte sedimentation rate (ESR)
- D. Hemoglobin and hematocrit levels
Correct Answer: A
Rationale: The correct answer is A: White blood cell count (WBC). Monitoring the white blood cell count is crucial when caring for a patient with an infection as it helps assess the body's response to the infection. An elevated white blood cell count often indicates an active infection or inflammation, while a decreasing count may signal improvement or potential complications. C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) are nonspecific markers of inflammation and not as specific to monitoring infection progression as the white blood cell count. Hemoglobin and hematocrit levels are important for assessing oxygen-carrying capacity and blood volume, but they are not the primary indicators for monitoring infection.
