Nursing Elites

1. A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which laboratory test should the nurse monitor to determine the effectiveness of the medication?

• A. Platelet count.
• B. Prothrombin time (PT) and international normalized ratio (INR).
• C. Activated partial thromboplastin time (aPTT).
• D. Fibrinogen level.

Correct answer: B

Rationale: Prothrombin time (PT) and international normalized ratio (INR) are essential laboratory tests to monitor the effectiveness of warfarin (Coumadin) therapy. These tests help assess the clotting time and the desired anticoagulant effect of the medication. Monitoring PT and INR levels is crucial to ensure that the client is within the therapeutic range, reducing the risk of bleeding or clotting complications associated with warfarin therapy. Platelet count (Choice A) measures the number of platelets in the blood and is not specific for monitoring warfarin therapy. Activated partial thromboplastin time (aPTT) (Choice C) is more commonly used to monitor heparin therapy, not warfarin. Fibrinogen level (Choice D) assesses the amount of fibrinogen in the blood and is not a specific test for monitoring warfarin therapy.

2. A client with a history of diabetes mellitus presents with confusion, sweating, and palpitations. What should the nurse do first?

• A. Check the client's blood glucose level.
• B. Administer 10 units of insulin.
• C. Give the client a high-protein snack.
• D. Measure the client's blood pressure.

Correct answer: A

Rationale: The correct first action for a client presenting with confusion, sweating, and palpitations, suggestive of hypoglycemia, is to check the client's blood glucose level. This step helps to confirm if the symptoms are due to low blood sugar levels and guides appropriate interventions. Administering insulin without knowing the current blood glucose level can be dangerous and is not recommended as the initial step. Offering a high-protein snack may be necessary after confirming hypoglycemia, but checking the blood glucose level takes precedence. Measuring blood pressure is not the priority in this situation; addressing hypoglycemia is the immediate concern.

3. The healthcare provider prescribes 15 mg/kg of Streptomycin for an infant weighing 4 pounds. The drug is diluted in 25 ml of D5W to run over 8 hours. How much Streptomycin will the infant receive?

• A. 9 mg
• B. 18 mg
• C. 27 mg
• D. 36 mg

Correct answer: A

Rationale: To calculate the dosage, first, convert the weight from pounds to kg (4 lbs / 2.2 ≈ 1.82 kg). Then, multiply by the prescribed mg/kg (15 mg/kg * 1.82 kg ≈ 27.3 mg). However, since the question asks for the closest correct option, the infant will receive approximately 9 mg.

4. The sister of a patient diagnosed with BRCA gene-related breast cancer asks the nurse, 'Do you think I should be tested for the gene?' Which response by the nurse is most appropriate?

• A. In most cases, breast cancer is not caused by the BRCA gene.
• B. It depends on how you will feel if the test is positive for the BRCA gene.
• C. There are many things to consider before deciding to have genetic testing.
• D. You should decide first whether you are willing to have a bilateral mastectomy.

Correct answer: C

Rationale: The most appropriate response by the nurse is C: 'There are many things to consider before deciding to have genetic testing.' Genetic testing for BRCA gene mutations is a complex decision that involves various factors such as emotional readiness, potential impact on insurance and employability, and the implications of test results. Option A is incorrect because although most breast cancers are not related to BRCA gene mutations, individuals with these mutations have a significantly higher risk. Option B is not ideal as it oversimplifies the decision-making process by focusing solely on emotional aspects. Option D is incorrect as it implies a predetermined course of action (mastectomy) before even undergoing genetic testing, which is not appropriate.

5. When a client expresses, 'I don't know how I will go on' while discussing feelings related to a recent loss, the nurse remains silent. What is the most likely reason for the nurse's behavior?

• A. The nurse is indicating disapproval of the statement.
• B. The nurse is showing respect for the client's loss.
• C. Silence is mirroring the client's sadness.
• D. Silence enables the client to contemplate what was expressed.

Correct answer: D

Rationale: In therapeutic communication, silence can offer the client an opportunity to process their emotions and thoughts. By remaining silent, the nurse provides a space for the client to reflect on their own words, facilitating deeper exploration and understanding of their feelings.
