The nurse is caring for a client who is receiving a continuous intravenous infusion of heparin. Which laboratory value should the nurse monitor to evaluate the effectiveness of the therapy?
- A. Platelet count
- B. Prothrombin time (PT)
- C. Partial thromboplastin time (PTT)
- D. Hemoglobin level
Correct Answer: C
Rationale: The correct answer is C: Partial thromboplastin time (PTT). PTT measures the effectiveness of heparin therapy by assessing the clotting time. With heparin being an anticoagulant, monitoring PTT helps ensure the client is within the therapeutic range to prevent clot formation. A - Platelet count assesses risk of bleeding, not heparin effectiveness. B - Prothrombin time (PT) is used to monitor warfarin therapy, not heparin. D - Hemoglobin level monitors for anemia, not heparin effectiveness.

A 3-year-old boy is brought to the emergency center with dysphagia, drooling, a fever of 102°F, and stridor. Which intervention should the nurse implement first?
- A. Place the child in a mist tent
- B. Obtain a sputum culture
- C. Prepare for an emergent tracheostomy
- D. Examine the child's oropharynx and report the findings to the healthcare provider
Correct Answer: A
Rationale: The correct answer is A: Place the child in a mist tent. This intervention is crucial in managing a child with croup, which presents with stridor, fever, and respiratory distress. Placing the child in a mist tent provides humidified air, which can help reduce airway inflammation and ease breathing. It is the first-line treatment for croup and should be initiated promptly to relieve the child's symptoms. Obtaining a sputum culture (B) is not necessary in this scenario as the child's presentation is consistent with croup, which is a clinical diagnosis. Preparing for an emergent tracheostomy (C) is an invasive procedure that should only be considered if other treatments fail. Examining the child's oropharynx (D) can be helpful but is not the most urgent intervention in this situation.
An experienced nurse tells the nurse-manager that working with a new graduate is impossible because the new graduate will not listen to suggestions. The new graduate comes to the nurse-manager describing the senior nurse's attitude as challenging and offensive. What action is best for the nurse manager to take?
- A. Have both nurses meet separately with the staff mental health consultant
- B. Listen actively to both nurses and offer suggestions to solve the dilemma
- C. Ask the senior nurse to examine mentoring strategies used with the new graduate
- D. Ask the nurses to meet with the nurse-manager to identify ways of working together
Correct Answer: D
Rationale: The correct answer is D. The nurse-manager should ask the nurses to meet to identify ways of working together. This is the best action because it promotes open communication, collaboration, and conflict resolution between the two nurses. By facilitating a discussion between them, the nurse-manager can help address the underlying issues, clarify misunderstandings, and find common ground for effective teamwork. This approach encourages mutual understanding and fosters a positive working relationship.
A: Having both nurses meet separately with the staff mental health consultant does not directly address the conflict between them.
B: While listening actively and offering suggestions is important, involving both nurses in the discussion is crucial for resolving the conflict.
C: Asking the senior nurse to examine mentoring strategies does not involve the new graduate in the conversation and may not address the overall issue.
The nurse is caring for a client who is receiving heparin therapy. Which laboratory value should the nurse monitor to determine the effectiveness of the therapy?
- A. Prothrombin time (PT)
- B. Partial thromboplastin time (PTT)
- C. International normalized ratio (INR)
- D. Activated partial thromboplastin time (aPTT)
Correct Answer: C
Rationale: Rationale:
1. Heparin primarily affects the intrinsic pathway of coagulation.
2. International Normalized Ratio (INR) is used to monitor the effectiveness of anticoagulation therapy.
3. INR is more specific for monitoring heparin therapy compared to other options.
4. Prothrombin Time (PT) and Activated Partial Thromboplastin Time (aPTT) are not as accurate for heparin monitoring.
5. Partial Thromboplastin Time (PTT) is used to monitor heparin therapy, but INR is a more precise indicator of heparin's effect.
Oxygen at liters/min per nasal cannula PRN difficult breathing is prescribed for a client with pneumonia. Which nursing intervention is effective in preventing oxygen toxicity?
- A. Avoiding the administration of high levels of oxygen for extended periods.
- B. Administering a sedative at bedtime to slow the client's respiratory rate.
- C. Removing the nasal cannula during the night to prevent oxygen buildup.
- D. Running oxygen through a hydration source prior to administration.
Correct Answer: A
Rationale: Correct Answer: A
Rationale:
1. High levels of oxygen over a prolonged period can lead to oxygen toxicity.
2. Oxygen toxicity can cause lung damage and respiratory distress.
3. To prevent oxygen toxicity, it is crucial to monitor and limit the duration and amount of oxygen administered.
4. Therefore, avoiding the administration of high levels of oxygen for extended periods is the most effective intervention to prevent oxygen toxicity.
Summary of other choices:
B: Administering a sedative does not address the root cause of oxygen toxicity and can mask symptoms.
C: Removing the nasal cannula at night can lead to hypoxia and is not a safe practice.
D: Running oxygen through a hydration source does not prevent oxygen toxicity and is not a recognized intervention.
The nurse assesses a client who is receiving an infusion of 5% dextrose in water with 20 mEq of potassium chloride. The client has oliguria and a serum potassium level of 6.5 mEq/L. What action should the nurse implement first?
- A. Notify the healthcare provider of the laboratory results
- B. Decrease the rate of the IV infusion
- C. Stop the infusion
- D. Administer sodium polystyrene sulfonate (Kayexalate)
Correct Answer: C
Rationale: The correct action for the nurse to implement first is to stop the infusion (Choice C). Oliguria and a high serum potassium level indicate the client is at risk for hyperkalemia, which can be exacerbated by the potassium chloride infusion. Stopping the infusion is crucial to prevent further elevation of potassium levels and potential cardiac complications.
Choice A (Notify the healthcare provider) is not the first action as immediate intervention is needed to prevent harm. Choice B (Decrease the rate of the IV infusion) is not sufficient to address the immediate risk of hyperkalemia. Choice D (Administer sodium polystyrene sulfonate) is not appropriate as the first action and should only be considered after stabilizing the client's condition.
