NCLEX RN Exam Prep Questions
Question 1 of 5
What term is used to refer to generalized wasting of body tissues and malnutrition?
Correct Answer: D
Rationale: Cachexia is the correct term used to describe the generalized wasting of body tissues, ill health, and malnutrition associated with some chronic diseases. It involves a loss of fat tissue to protect the bones and joints. Clients with cachexia are at risk of pressure ulcers and other complications due to malnutrition and poor health. Entropion refers to an eyelid condition, confabulation is a memory disturbance, and induration is the abnormal hardening of a part of the body.
Question 2 of 5
Which statement best describes evidence-based practice?
Correct Answer: D
Rationale: Evidence-based practice involves utilizing the most effective, current, and relevant information to inform nursing care decisions for optimal client outcomes. While research reports and data collection are important components of evidence-based practice, the essence lies in integrating all available information to determine the best course of action. Monitoring compliance with standards, as described in choices A and C, is essential for quality assurance but does not capture the comprehensive nature of evidence-based practice.
Question 3 of 5
Which of the following statements best describes substance P?
Correct Answer: D
Rationale: Substance P is a neurotransmitter found in the brain and the dorsal horn of the spinal column, not just in the brain. It is associated with pain transmission and modulation. Substance P is known to cause inflammation, edema, and pain. While it plays a role in pain perception, it does not decrease a client's sensitivity to pain (
Choice
A), nor are its levels typically drawn before administering narcotic analgesics (
Choice
B). Although substance P is involved in pain control, it is not responsible for managing depression (
Choice
C).
Therefore, the correct statement is that substance P is found in the dorsal horn of the spinal column.
Question 4 of 5
Which of the following is a fat-soluble vitamin?
Correct Answer: B
Rationale: The correct answer is Vitamin D. Fat-soluble vitamins are those that can be stored in the body, allowing excess amounts to be stored for later use. While this storage ability can help prevent deficiencies, it also poses a risk of toxicity. The fat-soluble vitamins are A, E, D, and K.
Choice A, Vitamin C, is water-soluble, not fat-soluble.
Choice C, Vitamin B-6, and
Choice D, Riboflavin, are also water-soluble vitamins and not fat-soluble.
Question 5 of 5
A healthcare professional is preparing to administer an enteral feeding through a gastrostomy tube. Before administering the feeding, the healthcare professional aspirates some stomach contents and checks the pH. The result is 3.9. What is the next action of the healthcare professional?
Correct Answer: A
Rationale: When the pH of the aspirated stomach contents is 4 or less, it indicates that the gastrostomy tube is in the stomach, confirming correct placement. A pH of 3.9 falls within this range, so the healthcare professional can proceed with administering the enteral feeding. There is no need to adjust the tube placement, flush with water, or contact the physician in this situation as the tube is appropriately positioned for feeding.
