Nursing Elites

1. Which diagnostic test is used to confirm tuberculosis (TB) infection?

• A. Chest X-ray
• B. Sputum culture
• C. Skin test (Mantoux)
• D. MRI

Correct answer: C

Rationale: The Mantoux skin test, also known as the Tuberculin Skin Test (TST), is used to confirm tuberculosis (TB) infection. This test involves injecting a small amount of tuberculin protein derivative under the top layer of the skin and then evaluating the immune system's response to the protein. A positive reaction indicates exposure to the TB bacteria. Chest X-rays are used to detect abnormalities in the lungs caused by TB but are not confirmatory. Sputum culture is used to identify the presence of TB bacteria in the sputum. MRIs are not typically used as a primary diagnostic tool for TB.

2. A nurse is caring for a client who is at 38 weeks of gestation and has preeclampsia. Which of the following findings should the nurse report to the provider?

• A. Fetal heart rate of 110/min
• B. 1+ pitting edema
• C. Blood pressure 138/80 mm Hg
• D. Urine output of 20 mL/hr

Correct answer: D

Rationale: The correct answer is D. Urine output less than 30 mL/hr indicates decreased kidney perfusion, which is a serious complication of preeclampsia. Reporting this finding is crucial for prompt intervention. Choices A, B, and C are not the priority as fetal heart rate of 110/min, 1+ pitting edema, and blood pressure of 138/80 mm Hg are within normal limits for a client with preeclampsia at 38 weeks of gestation.

3. A nurse is caring for an infant who has a prescription for continuous pulse oximetry. Which of the following is an appropriate action for the nurse to take?

• A. Place the infant under a radiant warmer
• B. Move the probe site every 3 hours
• C. Heat the skin one minute prior to placing the probe
• D. Place a sensor on the index finger

Correct answer: B

Rationale: The correct answer is to move the probe site every 3 hours. This action helps prevent skin breakdown and ensures accurate readings. Placing the infant under a radiant warmer (Choice A) is not necessary for pulse oximetry monitoring. Heating the skin before placing the probe (Choice C) can potentially cause burns in infants. Placing a sensor on the index finger (Choice D) is not the standard practice for continuous pulse oximetry in infants.

4. A nurse is caring for a client who has deep vein thrombosis of the left lower extremity. Which of the following actions should the nurse take?

• A. Position the client with the affected extremity higher than the heart
• B. Administration of acetaminophen
• C. Massage the affected extremity every 4 hours
• D. Withhold heparin IV infusion

Correct answer: D

Rationale: The correct action for the nurse to take when caring for a client with deep vein thrombosis is to withhold heparin IV infusion. Administering heparin is crucial in managing deep vein thrombosis by preventing further clot formation. Positioning the affected extremity higher than the heart (Choice A) promotes venous return and reduces swelling. Acetaminophen (Choice B) can be given for pain relief. Massaging the affected extremity (Choice C) is contraindicated as it can dislodge a clot, leading to serious complications.

5. A nurse is caring for a client with heart failure receiving digoxin. Which of the following findings should the nurse report to the provider?

• A. Heart rate 60/min.
• B. Blood pressure 110/70 mm Hg.
• C. Serum potassium 4 mEq/L.
• D. Blood pressure 120/80 mm Hg.

Correct answer: B

Rationale: The correct answer is B. A blood pressure of 110/70 mm Hg is a finding that the nurse should report to the provider when caring for a client with heart failure receiving digoxin. Digoxin can cause hypotension, so a low blood pressure reading should be reported promptly to the provider for further evaluation and management. Choices A, C, and D are within normal ranges and would not require immediate reporting. A heart rate of 60/min is considered normal, but any further decrease should be monitored. A serum potassium level of 4 mEq/L is also within the normal range. A blood pressure of 120/80 mm Hg is typically considered normal as well.
