Nursing Elites

1. A nurse is preparing to mix NPH and regular insulin in the same syringe. Which of the following actions should the nurse take?

• A. Inject air into the NPH insulin vial.
• B. Withdraw the prescribed dose of regular insulin.
• C. Withdraw the prescribed dose of NPH insulin.
• D. Mix the two insulins in separate syringes.

Correct answer: A

Rationale: When mixing NPH and regular insulin in the same syringe, the nurse should first inject air into the NPH insulin vial. This action prevents contamination by allowing an easier withdrawal of the correct dose of NPH insulin after withdrawing the regular insulin. Withdrawing the prescribed dose of regular insulin (Choice B) is incorrect as it does not address the initial step of injecting air into the NPH vial. Similarly, withdrawing the prescribed dose of NPH insulin (Choice C) is incorrect as it skips the crucial first step. Mixing the two insulins in separate syringes (Choice D) is not ideal since combining them in one syringe is a common practice to reduce the number of injections for the patient.

2. A nurse is assisting with the development of an informed document for participation in a research study. Which of the following information should the nurse include?

• A. A statement that participants can leave the study at will.
• B. An assignment of the participant to either the experimental or control group.
• C. A list of the clients participating in the study.
• D. A description of the framework the researchers will use to evaluate the data.

Correct answer: A

Rationale: The correct answer is A: 'A statement that participants can leave the study at will.' This information is crucial to include in the informed document to ensure that participants are aware of their right to withdraw from the study at any time without any negative consequences. Choice B is incorrect because participants should not be assigned to experimental or control groups without their knowledge and consent. Choice C is incorrect because disclosing a list of clients participating in the study violates confidentiality. Choice D is incorrect as the description of the data evaluation framework is important but not as critical as ensuring participants know they can leave the study at will.

3. A nurse is caring for a client who is receiving warfarin therapy. Which of the following laboratory results indicates the need for an increase in the dose of warfarin?

• A. PT 28 seconds
• B. INR 1.2
• C. aPTT 40 seconds
• D. Fibrinogen 350 mg/dL

Correct answer: B

Rationale: An INR of 1.2 is below the therapeutic range for a client on warfarin, indicating inadequate anticoagulation. Therefore, the client would require an increase in the dose of warfarin to achieve the desired therapeutic effect. Choices A, C, and D are not indicative of the need for a dose increase in warfarin therapy. PT of 28 seconds is within the therapeutic range, aPTT of 40 seconds is also within the normal range, and fibrinogen level of 350 mg/dL does not provide information about the anticoagulant effect of warfarin.

4. Which electrolyte imbalance is most concerning in a patient taking digoxin?

• A. Monitor potassium levels
• B. Monitor calcium levels
• C. Monitor sodium levels
• D. Monitor magnesium levels

Correct answer: A

Rationale: The correct answer is to monitor potassium levels. Patients taking digoxin are at risk of developing toxicity due to hypokalemia. Low potassium levels can potentiate the toxic effects of digoxin on the heart, leading to serious arrhythmias. Monitoring calcium levels (Choice B) is not the primary concern in patients taking digoxin. While calcium levels play a role in cardiac function, hypocalcemia is not directly associated with digoxin toxicity. Monitoring sodium levels (Choice C) is important for other conditions but is not the primary concern in a patient taking digoxin. Monitoring magnesium levels (Choice D) is also essential, but hypomagnesemia is not as directly linked to digoxin toxicity as hypokalemia.

5. How should a healthcare professional monitor for infection in a patient with a central line?

• A. Check the central line dressing daily
• B. Monitor for signs of redness
• C. Check for abnormal breath sounds
• D. Monitor temperature

Correct answer: A

Rationale: Correct answer: A. Checking the central line dressing daily is crucial to monitor for signs of infection around the insertion site. This practice helps in early detection of any changes such as redness, swelling, or discharge, which are indicators of a potential infection. Monitoring for signs of redness (choice B) is limited as redness alone may not always indicate an infection; other symptoms like discharge and tenderness should also be observed. Checking for abnormal breath sounds (choice C) is not directly related to monitoring central line infections. Monitoring temperature (choice D) is important for detecting systemic signs of infection but may not specifically indicate an infection related to the central line site.
