Nursing Elites

1. A healthcare professional is verifying nasogastric tube placement by the pH of aspirated gastric fluid. Which of the following pH values provides a good indication of correct tube placement?

• A. 2
• B. 5
• C. 7
• D. 9

Correct answer: A

Rationale: The correct answer is A: '2'. Gastric contents with a pH between 0 and 4 provide a good indication of appropriate tube placement. A pH of 2 is within this range, indicating that the tube is correctly placed in the stomach. Choices B, C, and D are incorrect because a pH of 5, 7, or 9 does not fall within the expected acidic pH range of gastric fluid.

2. A nurse is preparing to administer regular insulin and NPH insulin. What is the proper sequence of events the nurse should follow?

• A. Inspect the vials for contamination.
• B. Withdraw regular insulin first, then NPH.
• C. Inject air into the NPH insulin vial first.
• D. Roll the NPH insulin vial between the hands to mix.

Correct answer: A

Rationale: The correct sequence of events for administering regular insulin and NPH insulin begins with inspecting the vials for contamination to ensure patient safety. Rolling the NPH insulin vial between the hands to mix and injecting air into the NPH insulin vial should follow the inspection step. Afterward, the nurse should inject air into the regular insulin vial and then withdraw the regular insulin first. Option A is the correct answer as it outlines the initial crucial step in the administration process. Option B is incorrect as it provides the incorrect order of withdrawing the insulins. Option C is incorrect as injecting air into the NPH insulin vial should come after inspecting the vials. Option D is incorrect as rolling the NPH insulin vial should be done after inspecting the vials and injecting air into the NPH insulin vial.

3. A nurse is caring for a client who has a new diagnosis of tuberculosis (TB). The client has a productive cough and is started on airborne precautions. Which of the following interventions should the nurse implement?

• A. Wear an N95 respirator mask when caring for the client.
• B. Place the client in a semi-private room.
• C. Have the client wear a surgical mask during meals.
• D. Use a negative pressure air filtration system.

Correct answer: A

Rationale: The correct answer is to wear an N95 respirator mask when caring for the client with TB. This is crucial to prevent the nurse from inhaling the airborne particles that spread the infection. Choice B is incorrect because placing the client in a semi-private room does not address the protection of the nurse. Choice C is incorrect as having the client wear a surgical mask during meals is not sufficient to protect the nurse during all interactions. Choice D is incorrect as using a negative pressure air filtration system is more applicable to airborne infection isolation rooms in healthcare settings and not a standard intervention for nurses caring for a single client with TB.

4. A nurse in the telemetry unit is receiving the laboratory findings for an adult male client who is being treated for a myocardial infarction. Which of the following is an expected finding for the client?

• A. Troponin I (TnI) 8 ng/mL
• B. Brain natriuretic peptide (BNP) 10 ng/L
• C. Alanine aminotransferase (ALT) 45 units/L
• D. High-density lipoprotein (HDL) 75 mg/dL

Correct answer: A

Rationale: The correct answer is A. Troponin I is a specific marker for myocardial infarction, and levels of 8 ng/mL are elevated, indicating heart muscle damage. Brain natriuretic peptide (BNP) is more related to heart failure rather than myocardial infarction, making choice B incorrect. Alanine aminotransferase (ALT) is a liver enzyme and not specific to myocardial infarction, so choice C is incorrect. High-density lipoprotein (HDL) is a type of cholesterol and is not typically used to diagnose or monitor myocardial infarction, making choice D incorrect.

5. A nurse is caring for a client prescribed sildenafil for erectile dysfunction. Which of the following should the nurse monitor?

• A. Blood pressure
• B. Heart rate
• C. Temperature
• D. Respiratory rate

Correct answer: A

Rationale: The correct answer is A: Blood pressure. Sildenafil, a medication for erectile dysfunction, can cause changes in blood pressure. The nurse should monitor for hypotension as a potential side effect. Monitoring heart rate (choice B) is not a priority when administering sildenafil unless there are pre-existing heart conditions. Temperature (choice C) and respiratory rate (choice D) are typically not directly affected by sildenafil administration, making them less relevant for monitoring in this case.
