NCLEX RN Exam Review Answers
1. A patient asks the nurse why they must have a heparin injection. What is the nurse's best response?
- A. Heparin will dissolve clots that you have.
- B. Heparin will reduce the platelets that make your blood clot.
- C. Heparin will work better than warfarin.
- D. Heparin will prevent new clots from developing.
Correct answer: D
Rationale: The correct answer is D: 'Heparin will prevent new clots from developing.' Heparin is an anticoagulant medication that helps prevent the formation of new blood clots. It does not dissolve existing clots (choice A), reduce platelets (choice B), or necessarily work 'better' than warfarin (choice C) but rather functions differently. The primary action of heparin is to prevent the development of new clots, especially in conditions where clot formation is a concern.
2. During a physical exam, a healthcare professional assisting a client suspected of having meningitis bends the client's leg at the hip to a 90-degree angle. When attempting to extend the leg at the knee, the client experiences severe pain. What type of test is being performed?
- A. Brudzinski's sign
- B. Romberg's sign
- C. Kernig's sign
- D. Babinski's sign
Correct answer: C
Rationale: The healthcare professional is performing Kernig's sign, a test for meningeal irritation often seen in meningitis cases. Kernig's sign involves bending the client's leg at a 90-degree angle at the hip and then attempting to extend the leg at the knee. Severe pain during this maneuver indicates a positive Kernig's sign, suggesting irritation of the meningeal membranes. Brudzinski's sign involves flexing the neck causing involuntary flexion of the hips and knees; Romberg's sign assesses balance and proprioception; Babinski's sign checks for abnormal reflexes in the foot.
3. Rhogam is most often used to treat____ mothers that have a ____ infant.
- A. RH positive, RH positive
- B. RH positive, RH negative
- C. RH negative, RH positive
- D. RH negative, RH negative
Correct answer: C
Rationale: Rhogam is administered to RH-negative mothers who have an RH-positive infant to prevent the development of anti-RH antibodies in the mother's system. Choice A (RH positive, RH positive) is incorrect because Rhogam is not used when both mother and infant are RH positive. Choice B (RH positive, RH negative) is incorrect because Rhogam is used when the mother is RH negative, not RH positive. Choice D (RH negative, RH negative) is incorrect as Rhogam is not typically needed if both mother and infant are RH negative.
4. Which question should the nurse ask the parents of a child suspected of having glomerulonephritis?
- A. Did your child fall off a bike onto the handlebars?
- B. Has the child had persistent nausea and vomiting?
- C. Has the child been itching or had a rash anytime in the last week?
- D. Has the child had a sore throat or a throat infection in the last few weeks?
Correct answer: D
Rationale: Glomerulonephritis refers to a group of kidney disorders characterized by inflammatory injury in the glomerulus. Group A ?-hemolytic streptococcal infection is a common cause of glomerulonephritis. Children with glomerulonephritis often develop symptoms after a throat infection caused by streptococcal bacteria. Therefore, asking about a sore throat or throat infection in the last few weeks is crucial to assess the possible link to glomerulonephritis. Choices A, B, and C are not directly associated with the pathophysiology of glomerulonephritis. Asking about falling off a bike, nausea and vomiting, or itching and rash do not provide relevant information for assessing glomerulonephritis in this context.
5. Which of the following medications taken by the patient is least likely to cause urine discoloration?
- A. Sulfasalazine
- B. Levodopa
- C. Phenolphthalein
- D. Aspirin
Correct answer: D
Rationale: The correct answer is Aspirin. Aspirin is not known to cause urine discoloration. Sulfasalazine is associated with causing orange-yellow discoloration of urine. Levodopa can cause darkening of urine to a brown or black color. Phenolphthalein has been linked to pink or red discoloration of urine. Therefore, among the options provided, Aspirin is the medication least likely to cause urine discoloration.
