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. When assessing a child admitted to the hospital with pyloric stenosis, which symptom would the nurse likely find when asking the parent about the child's symptoms?
- A. Watery diarrhea
- B. Projectile vomiting
- C. Increased urine output
- D. Vomiting large amounts of bile
Correct answer: B
Rationale: In pyloric stenosis, hypertrophy of the circular muscles of the pylorus causes narrowing of the pyloric canal between the stomach and the duodenum. The hallmark symptom of pyloric stenosis is projectile vomiting, which is the forceful expulsion of stomach contents. Other common symptoms include irritability, hunger and crying, constipation, and signs of dehydration. Watery diarrhea (Choice A) is not a typical symptom of pyloric stenosis. Increased urine output (Choice C) is not directly associated with this condition. Vomiting large amounts of bile (Choice D) is not a characteristic symptom of pyloric stenosis; instead, the vomitus in pyloric stenosis is non-bilious.
3. The parents of a newborn have been told that their child was born with bladder exstrophy, and the parents ask the nurse about this condition. Which explanation, given by the parents, indicates understanding of this condition?
- A. ''It's a hereditary disorder that occurs in every other generation.''
- B. ''It is caused by the use of medications taken by the mother during pregnancy.''
- C. ''It is a condition in which the urinary bladder is abnormally located in the pelvic cavity.''
- D. ''It's an extrusion of the urinary bladder to the outside of the body through a defect in the lower abdominal wall.''
Correct answer: D
Rationale: Bladder exstrophy is a congenital anomaly characterized by the extrusion of the urinary bladder to the outside of the body through a defect in the lower abdominal wall. The cause of bladder exstrophy is not precisely known, but it is believed to be due to a developmental abnormality during embryogenesis. The condition is more common in male newborns. Choice A is incorrect as bladder exstrophy is not a hereditary disorder that occurs in every other generation. Choice B is incorrect as bladder exstrophy is not caused by medications taken by the mother during pregnancy. Choice C is incorrect as it describes the condition inaccurately; it is not just an abnormal location of the bladder in the pelvic cavity, but rather an extrusion of the bladder outside the body through a defect in the lower abdominal wall.
4. A 30-year-old woman is experiencing anaphylaxis from a bee sting. Emergency personnel have been called. The nurse notes the woman is breathing but short of breath. Which of the following interventions should the nurse do first?
- A. Initiate cardiopulmonary resuscitation
- B. Check for a pulse
- C. Ask the woman if she carries an emergency medical kit
- D. Stay with the woman until help comes
Correct answer: C
Rationale: In a situation where a patient is experiencing anaphylaxis, it is crucial to act swiftly. Asking the woman if she carries an emergency medical kit is the most appropriate initial intervention. Many individuals with a history of anaphylaxis carry epinephrine auto-injectors, such as epi-pens, which can be life-saving in such situations. Initiating cardiopulmonary resuscitation (CPR) is not indicated as the patient is breathing but short of breath, and CPR is not the first-line intervention for anaphylaxis. Checking for a pulse, though important, is not the initial priority in managing anaphylaxis. Staying with the woman until help arrives is essential for providing support and monitoring her condition, but confirming the availability of an emergency medical kit takes precedence to promptly address the anaphylactic reaction.
5. A fragile 87-year-old female has recently been admitted to the hospital with increased confusion and falls over the last two weeks. She is also noted to have a mild left hemiparesis. Which of the following tests is most likely to be performed?
- A. CBC (Complete Blood Count)
- B. ECG (Electrocardiogram)
- C. Thyroid Function Tests
- D. CT Scan
Correct answer: D
Rationale: A CT scan is most likely to be performed in this scenario. A CT scan would be done to further investigate the cause of the left hemiparesis. Noncontrast CT scanning is commonly used in the acute evaluation of patients with suspected acute stroke to assess for ischemic changes or hemorrhage in the brain. While a CBC may provide information on blood cell counts and general health status, it is not the primary test for evaluating hemiparesis. An ECG is used to assess heart function and rhythm, which is not the main concern in this case. Thyroid function tests evaluate thyroid hormone levels and are not typically the initial tests for evaluating hemiparesis and confusion.
