NCLEX Question of The Day

1. A healthcare professional is reviewing a patient's arterial blood gas values. Which of the following conditions apply under the following values? pH- 7.49 Bicarbonate ion 24 mEq/dl PaCO2 - 31 mmHg PaO2 - 52 mmHg FiO2 - 0.22

Correct answer: B

Rationale: The given blood gas values indicate respiratory alkalosis. A high pH and low PaCO2 level are consistent with respiratory alkalosis. In this scenario, no compensation for the alkalosis is noted, ruling out metabolic acidosis or alkalosis. Metabolic conditions would usually involve changes in bicarbonate levels, which remain within the normal range in this case.

2. An infection in a central venous access device is not eliminated by giving antibiotics through the catheter. How might bacterial glycocalyx contribute to this?

Correct answer: A

Rationale: Bacterial glycocalyx is a viscous polysaccharide or polypeptide slime that covers microbes. It plays a significant role in protecting bacteria by enhancing adherence to surfaces, resisting phagocytic engulfment by white blood cells, and preventing antibiotics from contacting the microbe. Choice A is correct because glycocalyx shields the bacteria from both antibiotics and the immune system, allowing the infection to persist. Choices B, C, and D are incorrect because glycocalyx does not neutralize antibiotics, compete for binding sites with antibiotics, or provide nutrients for microbial growth.

3. A nurse is returning phone calls in a pediatric clinic. Which of the following reports most requires the nurse's immediate attention and phone call?

Correct answer: A

Rationale: The correct answer is the 8-year-old boy with vomiting, slower movements, and a history of an atrioventricular shunt placement. This report requires immediate attention because the symptoms could indicate a blocked shunt, which is a serious medical condition needing urgent evaluation and intervention. Slower movements in the context of an atrioventricular shunt history could suggest increased intracranial pressure. The other choices involve less urgent issues: choice B describes post-exercise pain, choice C presents with a low-grade fever and headache that could be due to a mild infection, and choice D reports itching associated with a cast, which is a common issue and less critical compared to a potentially blocked shunt.

4. A patient asks a nurse the following question: Exposure to TB can be best identified with which of the following procedures?

Correct answer: B

Rationale: The Mantoux test, also known as the tuberculin skin test, is the most appropriate and accurate test to identify exposure to TB. This test involves injecting a small amount of PPD tuberculin under the top layer of the skin, and a positive reaction indicates exposure to the TB bacteria. Choice A, a chest x-ray, is useful for detecting active TB disease but not exposure. Choice C, a breath sounds examination, is not a specific test for TB exposure. Choice D, a sputum culture for Mycobacterium tuberculosis, is used to diagnose active TB infection rather than exposure.

5. A healthcare provider is caring for a patient who has experienced burns to the right lower extremity. According to the Rule of Nines, which of the following percentages most accurately describes the severity of the injury?

Correct answer: C

Rationale: According to the Rule of Nines, the right lower extremity accounts for 18% of the total body surface area. The Rule of Nines divides the body into regions, each representing 9% or a multiple of 9%, allowing for a quick estimation of the extent of burns. In this case, the correct answer is 18% as it corresponds to the percentage allocated for each lower extremity. Choices A, B, and D are incorrect as they do not match the standard allocation for the right lower extremity in the Rule of Nines.
