NCLEX RN Exam Review Answers
1. A patient is being treated in the Neurology Unit for Meningitis. Which of these is a priority assessment for the nurse to make?
- A. Assess the patient for nuchal rigidity
- B. Determine the patient's past exposure to infectious organisms
- C. Check the patient's WBC lab values
- D. Monitor for increased lethargy and drowsiness
Correct answer: D
Rationale: Monitoring for increased lethargy and drowsiness is crucial as these symptoms indicate a decreased level of consciousness, which is the cardinal sign of increased Intracranial Pressure (ICP). Elevated ICP can lead to serious complications and requires immediate intervention. Assessing for nuchal rigidity is important in suspected cases of meningitis but monitoring lethargy and drowsiness takes precedence due to its direct correlation with ICP. Determining past exposure to infectious organisms and checking WBC lab values are important for diagnosing and treating meningitis but do not directly address the immediate concern of increased ICP.
2. A client is in need of hemodialysis for end-stage renal failure. The physician has inserted an AV fistula. Which of the following nursing interventions is appropriate when caring for this access site?
- A. Assess for clotting in fistula tubing
- B. Apply a dressing over the fistula site
- C. Assess for a bruit or thrill at the site of the fistula
- D. Assess circulation proximal to the fistula site
Correct answer: A
Rationale: When caring for an AV fistula used for hemodialysis, it is important to assess for a bruit (a humming sound) or thrill (a vibrating sensation) at the site of the fistula. These indicate proper blood flow through the fistula, ensuring it is patent and suitable for hemodialysis. Assessing for clotting in fistula tubing (Choice A) is not a routine nursing intervention for AV fistulas. Applying a dressing over the fistula site (Choice B) is not necessary as the site needs to be accessible for hemodialysis. Assessing circulation proximal to the fistula site (Choice D) is important but not specific to caring for the access site of an AV fistula.
3. A child diagnosed with Hepatitis A is under the care of a healthcare provider. Which of the following precautions would be most important to take to prevent the transmission of this infectious disease?
- A. Encourage the Hepatitis A vaccine for family members and siblings
- B. Use needleless systems if possible; otherwise, use careful needle precautionary measures
- C. Teach the child and enforce strict and frequent hand washing
- D. Teach the child and family about the dangers of contaminated food and water
Correct answer: C
Rationale: The most crucial precaution to prevent the transmission of Hepatitis A is to emphasize strict and frequent hand washing. Hepatitis A is a virus that spreads through the oral-fecal route and can survive on human hands. Hand washing is the most effective measure to reduce the risk of transmission. Encouraging the Hepatitis A vaccine for family members and siblings (Choice A) is beneficial for prevention but not as directly impactful as hand washing. While needle precautions (Choice B) are important in healthcare settings, they are not directly relevant to preventing the spread of Hepatitis A. Teaching about the dangers of contaminated food and water (Choice D) is important for general hygiene but may not be as effective as emphasizing hand hygiene in preventing the spread of Hepatitis A.
4. A systolic blood pressure of 145 mm Hg is classified as:
- A. Normotensive
- B. Prehypertension
- C. Stage I hypertension
- D. Stage II hypertension
Correct answer: C
Rationale: A systolic blood pressure of 145 mm Hg falls within the range of 140-159 mm Hg, which is classified as Stage I hypertension. Normotensive individuals have a systolic blood pressure less than 120 mm Hg, making choice A incorrect. Prehypertension is characterized by a systolic blood pressure ranging from 120-139 mm Hg, excluding choice B. Stage II hypertension is diagnosed when the systolic blood pressure is greater than 160 mm Hg, making choice D incorrect. Therefore, the correct classification for a systolic blood pressure of 145 mm Hg is Stage I hypertension.
5. Which oxygen delivery system would provide the highest concentrations of oxygen to the client?
- A. Venturi mask
- B. Partial rebreather mask
- C. Non-rebreather mask
- D. Simple face mask
Correct answer: C
Rationale: The correct answer is the non-rebreather mask. This oxygen delivery system has a one-way valve that prevents exhaled air from entering the reservoir bag and one or more valves covering the air holes on the face mask itself to prevent the inhalation of room air but allow exhalation of air. When a tight seal is achieved around the mask, up to 100% of oxygen is available. Choice A, the Venturi mask, delivers precise oxygen concentrations but not as high as the non-rebreather mask. Choice B, the partial rebreather mask, allows the client to rebreathe some exhaled air, resulting in lower oxygen concentrations than the non-rebreather mask. Choice D, the simple face mask, delivers low to moderate oxygen concentrations and is not designed to provide the highest concentrations like the non-rebreather mask.
