Nursing Elites

1. A healthcare provider is reviewing laboratory results for a client who is receiving heparin therapy. Which of the following results indicates that the medication is effective?

• A. Platelets 250,000/mm³
• B. aPTT 60 seconds
• C. Hemoglobin 15 g/dL
• D. INR 1.5

Correct answer: B

Rationale: An aPTT of 60 seconds indicates that the client is receiving an effective dose of heparin. The activated partial thromboplastin time (aPTT) measures the time it takes for blood to clot and is used to monitor heparin therapy. A therapeutic range for aPTT during heparin therapy is usually 1.5 to 2 times the control value, which is around 25-35 seconds. Platelets, hemoglobin, and INR values are not direct indicators of the effectiveness of heparin therapy.

2. A client has a new prescription for levothyroxine. Which of the following findings should the nurse monitor for as a potential adverse effect of the medication?

• A. Increased heart rate.
• B. Weight loss.
• C. Hyperthermia.
• D. Decreased deep-tendon reflexes.

Correct answer: A

Rationale: Corrected Rationale: An increased heart rate is a common adverse effect of levothyroxine due to its role in boosting metabolism. Choice B, weight loss, is actually a therapeutic effect of levothyroxine as it helps in managing hypothyroidism by increasing the metabolic rate. Hyperthermia (Choice C) is not a typical adverse effect of levothyroxine. Decreased deep-tendon reflexes (Choice D) are not associated with levothyroxine use.

3. A client with asthma asks how to use a peak flow meter. Which of the following instructions should the nurse provide?

• A. Use the peak flow meter at the same time each day.
• B. Take a slow, deep breath and blow out as hard as you can.
• C. Keep a log of your peak flow readings.
• D. Perform the test before using any bronchodilators.

Correct answer: D

Rationale: The correct answer is to instruct the client to perform the peak flow test before using any bronchodilators. This is important because it provides the most accurate baseline measurement of lung function. Choice A is not necessarily crucial for the accuracy of the test. Choice B describes the technique for spirometry, not peak flow meter use. Choice C, while important for tracking trends, is not directly related to the accuracy of the initial measurement.

4. A client who has a new diagnosis of hypertension is being taught about dietary modifications by a nurse. Which of the following instructions should the nurse include?

• A. Limit fluid intake to 2 liters per day.
• B. Increase your intake of whole grains.
• C. Eat 3 large meals daily.
• D. Consume foods high in potassium.

Correct answer: B

Rationale: The correct answer is B: 'Increase your intake of whole grains.' Whole grains are beneficial for individuals with hypertension as they can help promote heart health. Whole grains are high in fiber, which can help lower blood pressure. Option A is incorrect as fluid intake should be adequate but not restricted to 2 liters per day. Option C is incorrect as it is recommended to have smaller, more frequent meals rather than 3 large meals to help manage hypertension. Option D is incorrect; although foods high in potassium can be beneficial for hypertension, the most appropriate dietary modification to include in this scenario is increasing whole grain intake.

5. A nurse is caring for a client who has depression and reports taking St. John's wort along with citalopram. The nurse should monitor the client for which of the following conditions as a result of an interaction between these substances?

• A. Serotonin syndrome
• B. Tardive dyskinesia
• C. Pseudo-parkinsonism
• D. Acute dystonia

Correct answer: A

Rationale: The correct answer is A: Serotonin syndrome. When a client takes St. John's wort, a herbal supplement, along with citalopram, a selective serotonin reuptake inhibitor (SSRI), there is a risk of developing serotonin syndrome. Serotonin syndrome is a potentially life-threatening condition characterized by symptoms such as confusion, agitation, fever, sweating, shivering, tremors, muscle rigidity, and in severe cases, seizures and coma. It is crucial for the nurse to monitor the client for these symptoms. Choices B, C, and D are incorrect because tardive dyskinesia is associated with long-term use of antipsychotic medications, pseudo-parkinsonism is a side effect of antipsychotic medications like haloperidol, and acute dystonia is a side effect of antipsychotic medications characterized by sustained muscle contractions.
