1. The client with deep vein thrombosis (DVT) is receiving anticoagulant therapy. Which laboratory test should the nurse monitor to evaluate the effectiveness of the therapy?
- A. Complete blood count (CBC)
- B. Activated partial thromboplastin time (aPTT)
- C. Serum electrolytes
- D. Liver function tests
Correct answer: B
Rationale: Activated partial thromboplastin time (aPTT) is the correct laboratory test to monitor the effectiveness of anticoagulant therapy, especially with heparin. A prolonged aPTT indicates effective anticoagulation, reducing the risk of further clot formation in the client with deep vein thrombosis (DVT). The other options, such as complete blood count (CBC), serum electrolytes, and liver function tests, do not directly assess the therapeutic effectiveness of anticoagulant therapy. Therefore, the correct answer is B.
2. A healthcare professional is preparing to administer a unit of packed red blood cells to a client. Which of the following actions should the healthcare professional take?
- A. Prime the blood tubing with normal saline.
- B. Verify the client’s identity using two identifiers.
- C. Infuse the blood rapidly over 30 minutes.
- D. Obtain the client’s vital signs every 4 hours during the transfusion.
Correct answer: B
Rationale: Verifying the client’s identity using two identifiers is a critical patient safety measure to ensure the correct patient receives the blood transfusion. This process involves checking the patient's identity using at least two unique identifiers, such as name, date of birth, or medical record number, to prevent administration errors. Priming the blood tubing with normal saline is necessary to ensure there are no air bubbles in the tubing, but it is not the immediate action required before administering the blood. Infusing packed red blood cells over 30 minutes is generally too rapid and can lead to adverse reactions; a slower rate is recommended for safe administration. Obtaining vital signs every 4 hours during the transfusion is not frequent enough to monitor the client adequately for potential transfusion reactions or complications; vital signs should be monitored more frequently, especially during the initial phase of the transfusion.
3. A client is admitted to the emergency department with a suspected myocardial infarction (MI). The nurse should prepare the client for which immediate diagnostic test?
- A. Chest x-ray
- B. Electrocardiogram (ECG)
- C. Echocardiogram
- D. Coronary angiography
Correct answer: B
Rationale: An Electrocardiogram (ECG) is the most immediate and essential test to diagnose a myocardial infarction (MI) and assess the extent of heart damage. An ECG can quickly identify changes in the heart's electrical activity, allowing prompt initiation of appropriate interventions. A chest x-ray (Choice A) may show other conditions affecting the heart, but it is not the immediate test of choice for diagnosing an MI. An echocardiogram (Choice C) and coronary angiography (Choice D) are valuable in further assessing cardiac function and anatomy post-MI but are not the first-line diagnostic tests due to their time-consuming nature compared to an ECG.
4. The healthcare provider is preparing to administer a beta blocker to a client with hypertension. What parameter should be checked before administering the medication?
- A. Serum potassium level
- B. Apical pulse
- C. Oxygen saturation
- D. Pupil reaction to light
Correct answer: B
Rationale: Before administering a beta blocker, it is crucial to check the apical pulse. Beta blockers have the potential to slow down the heart rate, making it essential to assess the pulse rate to ensure it is within the safe range before giving the medication. Checking the serum potassium level (choice A) is important when administering certain medications, but it is not specifically required before giving a beta blocker. Oxygen saturation (choice C) and pupil reaction to light (choice D) are not directly related to monitoring parameters for beta blocker administration.
5. A client is taking levothyroxine for hypothyroidism. Which of the following findings should indicate to the healthcare provider that the client is experiencing levothyroxine toxicity?
- A. Weight loss
- B. Insomnia
- C. Heat intolerance
- D. Dry skin
Correct answer: C
Rationale: Heat intolerance is a hallmark sign of levothyroxine toxicity. It indicates that the client may be receiving an excessive dose of levothyroxine, leading to hyperthyroid symptoms. This can happen when the dosage is too high, causing the body to have an excess of thyroid hormone. Weight loss is a common symptom of hyperthyroidism but alone does not specifically indicate levothyroxine toxicity. Insomnia can be related to hyperthyroidism but is not a specific sign of levothyroxine toxicity. Dry skin is more commonly associated with hypothyroidism rather than levothyroxine toxicity.
