1. How should a healthcare professional care for a patient with a central line?

A. Flush the line daily
B. Monitor for infection
C. Change the dressing weekly
D. Replace the central line every week

Correct answer: B

Rationale: When caring for a patient with a central line, monitoring for infection is crucial. This is because central lines can introduce bacteria into the bloodstream, leading to serious infections. While flushing the line daily and changing the dressing weekly are important aspects of central line care, monitoring for infection takes precedence. Infections can occur rapidly and have severe consequences, so early detection through vigilant monitoring is key. Replacing the central line every week is not a standard practice and should only be done when clinically indicated, such as in cases of infection or malfunction.

2. A charge nurse on a medical-surgical unit is planning assignments for a licensed practical nurse (LPN) who has been sent from the unit due to a staffing shortage. Which of the following clients should the nurse delegate to the LPN?

A. A client who has an Hgb of 6.3 g/dl and a prescription for packed RBCs.
B. A client who sustained a concussion and has unequal pupils.
C. A client who is postoperative following a bowel resection with an NG tube.
D. A client who fractured his femur yesterday and is experiencing shortness of breath.

Correct answer: C

Rationale: The correct answer is C because a client who is postoperative following a bowel resection with an NG tube can be delegated to an LPN as this involves routine postoperative care. Option A involves administering packed RBCs which requires assessment and monitoring for potential adverse reactions, not suitable for delegation to an LPN. Option B requires neurological assessment and close monitoring due to the concussion, which is beyond the scope of an LPN. Option D involves a client with a recent fracture and shortness of breath, which requires urgent assessment and intervention beyond the LPN's scope of practice.

3. A client with a new diagnosis of heart failure is receiving teaching from a nurse. Which of the following instructions should the nurse include?

A. Limit sodium intake to 4 grams per day.
B. Weigh yourself daily to monitor for fluid retention.
C. Drink 2 liters of water each day.
D. Increase physical activity gradually.

Correct answer: B

Rationale: The correct answer is B. Weighing oneself daily is crucial in monitoring fluid retention, a key aspect in managing heart failure. This helps in detecting early signs of fluid buildup, prompting timely interventions. Choice A is incorrect as the recommended sodium intake for heart failure clients is usually lower, around 2-3 grams daily. Choice C is incorrect because excessive water intake can worsen fluid retention in heart failure. Choice D is incorrect as clients with heart failure should consult healthcare providers before significantly altering their physical activity levels.

4. Which electrolyte imbalance is most common in patients receiving furosemide?

A. Hypokalemia
B. Hypercalcemia
C. Hyponatremia
D. Hyperkalemia

Correct answer: A

Rationale: The correct answer is A, Hypokalemia. Furosemide, a loop diuretic, commonly leads to potassium loss in the urine, causing hypokalemia. This electrolyte imbalance should be closely monitored in patients taking furosemide. Choices B, C, and D are incorrect because hypercalcemia, hyponatremia, and hyperkalemia are not typically associated with furosemide use.

5. What is the most critical lab value to monitor for a patient on heparin therapy?

A. Monitor aPTT levels
B. Monitor platelet count
C. Monitor INR levels
D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is to monitor aPTT levels. Activated Partial Thromboplastin Time (aPTT) is crucial for assessing the therapeutic effectiveness of heparin, as it reflects the intrinsic pathway of the coagulation cascade. Monitoring aPTT helps ensure that the patient is within the therapeutic range of heparin, minimizing the risk of bleeding complications. Platelet count (choice B) is important to assess for potential heparin-induced thrombocytopenia but is not the primary lab value to monitor during heparin therapy. INR levels (choice C) are monitored in patients on warfarin therapy, not heparin. Sodium levels (choice D) are not directly related to heparin therapy monitoring.
