Nursing Elites

1. A nurse is assessing a client who has asthma. Which of the following areas should the nurse evaluate as the most reliable indicator of central cyanosis?

• A. Oral mucosa
• B. Conjunctivae
• C. Soles of the feet
• D. Ear lobes

Correct answer: A

Rationale: Central cyanosis is best assessed by examining the oral mucosa, as it is a more reliable indicator compared to other areas like the conjunctivae, soles of the feet, and ear lobes. The oral mucosa reflects the oxygen saturation levels of the blood more accurately. Conjunctivae and ear lobes may show cyanosis, but they are not as reliable as the oral mucosa. The soles of the feet are not typically used to assess central cyanosis.

2. How should a healthcare provider respond to a patient who is exhibiting signs of acute myocardial infarction (AMI)?

• A. Calling for emergency assistance immediately
• B. Administering nitroglycerin as prescribed
• C. Monitoring the patient's cardiac rhythm
• D. Administering oxygen and preparing for ECG

Correct answer: A

Rationale: When a patient is exhibiting signs of acute myocardial infarction (AMI), the priority action is to call for emergency assistance immediately. This ensures that the patient receives prompt and appropriate care, including interventions such as administering oxygen, nitroglycerin, and monitoring cardiac rhythm. Administering nitroglycerin should only be done if prescribed by a healthcare provider after assessment and confirmation of AMI. Monitoring the patient's cardiac rhythm is important but not the initial action needed in this critical situation. Administering oxygen and preparing for an ECG are important interventions but should follow the immediate step of calling for emergency assistance.

3. A healthcare professional is preparing to insert an indwelling urinary catheter. What is the most important action to prevent infection?

• A. Use sterile gloves during the procedure.
• B. Clean the catheter insertion site with alcohol.
• C. Insert the catheter as quickly as possible.
• D. Use a smaller catheter size to minimize trauma.

Correct answer: A

Rationale: Using sterile gloves during catheter insertion is crucial to prevent infection. Sterile gloves help maintain asepsis during the procedure, reducing the risk of introducing microorganisms into the urinary tract. Cleaning the insertion site with alcohol, as mentioned in choice B, is important but not as critical as using sterile gloves. Choice C, inserting the catheter as quickly as possible, is not recommended as it can lead to errors and increase the risk of contamination. Choice D, using a smaller catheter size to minimize trauma, is not directly related to preventing infection but rather focuses on patient comfort and reducing tissue damage.

4. A nurse is preparing to administer ampicillin 500 mg IV bolus every 6 hours. Available is ampicillin 500 mg in 50 mL dextrose 5% in water (D5W) to infuse over 20 minutes. The nurse should set the IV pump to deliver how many mL/hr?

• A. 100 mL/hr
• B. 150 mL/hr
• C. 200 mL/hr
• D. 250 mL/hr

Correct answer: B

Rationale: To infuse 50 mL over 20 minutes, the pump should be set to 150 mL/hr. This calculation ensures the correct rate for the infusion of the medication. Choices A, C, and D are incorrect as they do not align with the correct calculation based on the given information.

5. What are the key considerations when administering medication via a nasogastric (NG) tube?

• A. Checking tube placement before administration
• B. Administering medication in liquid form whenever possible
• C. Crushing tablets and mixing them with water if needed
• D. Flushing the NG tube with water before and after medication

Correct answer: A

Rationale: The correct answer is A: Checking tube placement before administration. This is a crucial step to ensure that the medication reaches the stomach safely and does not end up in the lungs, which can lead to serious complications. Choice B is incorrect as not all medications can be administered in liquid form. Choice C is incorrect because crushing tablets can alter their effectiveness or cause harm. Choice D is incorrect as flushing the NG tube with water is not a standard practice before administering medication, unless specified by healthcare provider instructions.
