NCLEX RN Exam Review Answers
1. Why should a 30-year-old Caucasian woman who works the night shift take Vitamin D supplements?
- A. It's a standard part of the overall nutritional treatment for the prevention of osteomalacia.
- B. It helps your intestines absorb calcium, which is important for bone formation.
- C. It stimulates skin cells to produce calcium, which is then released into the bloodstream to be used for bone formation.
- D. Vitamin D supplements should not be taken by someone of your age.
Correct answer: B
Rationale: The correct answer is B: 'It helps your intestines absorb calcium, which is important for bone formation.' Vitamin D plays a crucial role in aiding the absorption of calcium from the intestines into the bloodstream, which is essential for bone health and formation. Choice A is incorrect because it does not specifically address the role of Vitamin D in calcium absorption. Choice C is incorrect as Vitamin D does not stimulate skin cells to produce calcium; rather, it helps regulate calcium levels in the body. Choice D is incorrect as age alone is not a contraindication for Vitamin D supplementation; the need for supplementation is based on individual health status and risk factors.
2. The healthcare provider is managing a 20 lbs (9 kg) 6-month-old with a 3-day history of diarrhea, occasional vomiting, and fever. Peripheral intravenous therapy has been initiated, with 5% dextrose in 0.33% normal saline with 20 mEq of potassium per liter infusing at 35 ml/hr. Which finding should be immediately reported to the healthcare provider?
- A. 3 episodes of vomiting in 1 hour.
- B. Periodic crying and irritability.
- C. Vigorous sucking on a pacifier.
- D. No measurable voiding in 4 hours.
Correct answer: D
Rationale: The critical finding that should be reported immediately to the healthcare provider is 'No measurable voiding in 4 hours.' This finding raises concerns about possible hyperkalemia, which can result from continued potassium administration and a decrease in urinary output. Hyperkalemia can lead to serious complications, including cardiac arrhythmias. The management of acute hyperkalemia involves interventions such as administering calcium to protect the heart, shifting potassium into cells, and enhancing potassium elimination from the body. The other choices do not indicate an urgent issue that requires immediate attention. Three episodes of vomiting in 1 hour can be concerning but may not be as immediately critical as the risk of hyperkalemia. Periodic crying and irritability are common in infants and may not indicate a severe complication. Vigorous sucking on a pacifier is a normal behavior in infants and does not signal a medical emergency.
3. A client is being assessed for risks of a pressure ulcer by a healthcare professional. What is the best description of what may be found with an early pressure ulcer in an African American client?
- A. Skin has a purple/bluish color
- B. Capillary refill is 1 second
- C. Skin appears blanched at the pressure site
- D. Tenting appears when checking skin turgor
Correct answer: A
Rationale: When assessing for signs of developing pressure ulcers in a client with dark skin, traditional signs like blanching may not be evident. In individuals with darker skin tones, the skin of an early pressure ulcer may present with a purple or bluish hue. This discoloration can be a crucial indicator of compromised circulation and tissue damage. Capillary refill, blanching, and tenting are more commonly used in the assessment of skin integrity and hydration levels but may not be as reliable in individuals with darker skin tones, making the purple/bluish color a key finding in this context.
4. A child is diagnosed with a Greenstick Fracture. Which of the following most accurately describes the broken bone?
- A. compound fracture of the fibula
- B. a partial break in a long bone
- C. fracture of the growth plate of the ulna near the wrist
- D. Colles fracture of the tibia
Correct answer: B
Rationale: A Greenstick Fracture is commonly found in children due to their bones being more flexible. This type of fracture occurs when a bone bends and partially breaks, resembling what happens when a green stick from a tree is bent in half. Therefore, the most accurate description of a Greenstick Fracture is 'a partial break in a long bone.' Choice A, 'compound fracture of the fibula,' is incorrect as a Greenstick Fracture is not a compound fracture. Choice C, 'fracture of the growth plate of the ulna near the wrist,' is incorrect as it describes a different type of fracture. Choice D, 'Colles fracture of the tibia,' is incorrect as it refers to a specific type of fracture in a different bone.
5. A client is being instructed in the use of an incentive spirometer. Which of the following statements from the nurse indicates correct teaching about using this device?
- A. Lie back in a reclining position while using the spirometer.
- B. Take slow deep breaths to reach your goal.
- C. Set a goal of using the spirometer at least 3 times per day.
- D. Practice coughing after taking 10 breaths.
Correct answer: D
Rationale: An incentive spirometer is a device used to improve lung function and reduce the risk of atelectasis. The correct way to use the spirometer is by sitting up and taking slow, deep breaths to achieve the set goal, not by lying back in a reclining position or taking rapid, quick breaths. Setting a goal of using the spirometer multiple times a day is beneficial, but it is not the best indicator of correct teaching. After using the spirometer, the client should practice coughing to help clear any loosened secretions that may have occurred during the breathing exercises.
