NCLEX PN Exam Cram Questions
Question 1 of 5
Which of the following arterial blood gas values indicates a patient may be experiencing a condition of metabolic acidosis?
Correct Answer: B
Rationale: The correct answer is B: Bicarbonate 15 mEq/L. In metabolic acidosis, the bicarbonate levels are lower than normal. A bicarbonate value of 15 mEq/L indicates a deficit in the buffer system, contributing to the acidosis. Choices A, C, and D are incorrect. Choice A, PaO2 90 mm Hg, reflects oxygen partial pressure and is not directly related to metabolic acidosis. Choice C, CO2 47 mm Hg, represents carbon dioxide levels and is more indicative of respiratory status. Choice D, pH 7.34, falls within the normal range (7.35-7.45) and does not confirm metabolic acidosis.
Question 2 of 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.
Question 3 of 5
Which instruction should be given in a health education class regarding testicular cancer?
Correct Answer: D
Rationale: The correct instruction for testicular cancer education is that testicular exams should be performed after a warm bath or shower as it relaxes the scrotum and makes the exam easier. Testicular exams should be done monthly by all men starting around age 15, not after the age of 30 (Choice A) or on a daily basis (Choice B), which is unnecessary and may lead to unnecessary anxiety. Reddening or darkening of the scrotum is not a normal finding (Choice C) and should be reported to a healthcare provider for further evaluation.
Question 4 of 5
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.
Question 5 of 5
Which of the following is not typically considered one of the main mechanisms of Type II Diabetes treatment?
Correct Answer: D
Rationale: Continuous Insulin is not typically considered one of the main mechanisms for treating Type II Diabetes. While medications, nutrition, and increased activity play crucial roles in managing Type II Diabetes, continuous insulin therapy is more common in Type I Diabetes or in specific cases of Type II Diabetes where other treatments are ineffective. Therefore, the correct answer is Continuous Insulin. Choices A, B, and C are mainstays in the treatment of Type II Diabetes, making them incorrect answers.
