The healthcare provider is caring for a patient who is taking warfarin (Coumadin). Which laboratory value should the healthcare provider monitor closely?
- A. Platelet count.
- B. Prothrombin time (PT).
- C. Hemoglobin level.
- D. White blood cell count.
Correct Answer: B
Rationale: The correct answer is B: Prothrombin time (PT). Warfarin is an anticoagulant medication that works by inhibiting clotting factors. Monitoring PT is essential to ensure the patient's blood is clotting within the desired range to prevent both bleeding and clotting events. Platelet count (A) assesses the quantity of platelets, not the clotting function. Hemoglobin level (C) evaluates red blood cell count and oxygen-carrying capacity. White blood cell count (D) assesses immune function and infection risk, not clotting ability. PT is directly related to warfarin's mechanism of action, making it the most crucial parameter to monitor.

A client with cirrhosis of the liver is experiencing pruritus. Which intervention should the nurse implement to help relieve the client's symptoms?
- A. Administer acetaminophen (Tylenol).
- B. Apply lotion to the skin.
- C. Encourage a high-protein diet.
- D. Provide a warm bath.
Correct Answer: B
Rationale: The correct answer is B: Apply lotion to the skin. Pruritus in cirrhosis is often due to dry skin. Applying lotion helps hydrate the skin, reducing itching. Acetaminophen (A) can worsen liver damage. High-protein diet (C) is not directly related to pruritus relief. Warm bath (D) may further dry the skin.
The nurse is caring for a client with hyperthyroidism. Which intervention should the nurse implement to manage the client's condition?
- A. Provide a high-calorie diet.
- B. Encourage frequent rest periods.
- C. Restrict fluid intake.
- D. Administer a stool softener.
Correct Answer: B
Rationale: The correct answer is B: Encourage frequent rest periods. For a client with hyperthyroidism, rest is crucial to conserve energy and support the body's recovery. Hyperthyroidism is characterized by increased metabolic rate, leading to fatigue and weakness. Rest periods help reduce metabolic demands and prevent exhaustion. A high-calorie diet (choice A) may be necessary to support increased metabolism but is not the priority. Restricting fluid intake (choice C) can lead to dehydration, which should be avoided in hyperthyroidism. Administering a stool softener (choice D) is unrelated to managing hyperthyroidism.
A client with coronary artery disease (CAD) is prescribed atorvastatin (Lipitor). Which laboratory value requires immediate intervention?
- A. Total cholesterol of 180 mg/dL.
- B. Low-density lipoprotein (LDL) of 200 mg/dL.
- C. Triglycerides of 150 mg/dL.
- D. High-density lipoprotein (HDL) of 40 mg/dL.
Correct Answer: B
Rationale: The correct answer is B: LDL of 200 mg/dL. Elevated LDL levels are a major risk factor for CAD and require immediate intervention. Atorvastatin (Lipitor) is used to lower LDL levels. High LDL contributes to plaque buildup in arteries.
A: Total cholesterol of 180 mg/dL is within the normal range and doesn't require immediate intervention.
C: Triglycerides of 150 mg/dL are also within the normal range and don't pose an immediate risk.
D: HDL of 40 mg/dL is considered low, but it is not as critical as high LDL levels in the context of CAD.
A client who has been receiving treatment for depression with a selective serotonin reuptake inhibitor (SSRI) reports experiencing decreased libido. What is the best response by the nurse?
- A. Decreased libido is a common side effect of SSRIs and may improve over time.
- B. I will notify your healthcare provider to discuss possible medication changes.
- C. You should take your medication with food to reduce side effects.
- D. Increase your daily exercise to help manage this side effect.
Correct Answer: B
Rationale: The correct response is B: I will notify your healthcare provider to discuss possible medication changes. This is the best choice because decreased libido is a common side effect of SSRIs that can significantly impact the client's quality of life. Consulting the healthcare provider is crucial to explore alternative treatment options or adjustments to improve the client's symptoms. Choices A, C, and D do not address the underlying issue of decreased libido and are unlikely to provide effective solutions. Choice A only acknowledges the side effect without offering a proactive solution. Choice C is unrelated to the sexual side effect and may not address the client's concerns. Choice D suggests a general lifestyle change that may not directly address the medication side effect. Consulting the healthcare provider for medication adjustments is the most appropriate action to address this specific side effect.
A client with a history of chronic heart failure is experiencing severe shortness of breath and has pink, frothy sputum. Which action should the nurse take first?
- A. Administer morphine sulfate.
- B. Place the client in a high Fowler's position.
- C. Initiate continuous ECG monitoring.
- D. Prepare the client for intubation.
Correct Answer: B
Rationale: The correct action for the nurse to take first is to place the client in a high Fowler's position (Choice B). This position helps improve lung expansion and oxygenation by reducing pressure on the diaphragm and improving ventilation. With severe shortness of breath and pink, frothy sputum, the priority is to optimize respiratory function. Administering morphine sulfate (Choice A) may be indicated later for pain and anxiety but is not the immediate priority. Initiating continuous ECG monitoring (Choice C) is important but not as urgent as addressing the respiratory distress. Preparing the client for intubation (Choice D) should be considered if respiratory distress worsens, but initial interventions should focus on improving oxygenation through positioning.
