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. Which of the following is NOT a warning sign that compensatory mechanisms in a patient in shock are failing?
- A. Increasing heart rate above normal for the patient's age.
- B. Absent peripheral pulses
- C. Decreasing level of consciousness
- D. Increasing blood pressure
Correct answer: D
Rationale: In a patient in shock, increasing blood pressure is not a sign that compensatory mechanisms are failing. As shock progresses and compensatory mechanisms fail, systolic blood pressure will decrease, leading to hypotension, which is a late and ominous sign in these patients. Therefore, choices A, B, and C are warning signs of failing compensatory mechanisms in shock: an increasing heart rate above normal, absent peripheral pulses, and decreasing level of consciousness, respectively. An increasing blood pressure is not indicative of compensatory failure in shock; instead, it may be a sign of compensatory mechanisms still trying to maintain perfusion pressure.
3. Mr. B is recovering from a surgical procedure that was performed four days ago. The nurse's assessment finds this client coughing up rust-colored sputum; his respiratory rate is 28/minute with expiratory grunting, and his lung sounds have coarse crackles on auscultation. Which of the following conditions is the most likely cause of these symptoms?
- A. Tuberculosis
- B. Pulmonary edema
- C. Pneumonia
- D. Histoplasmosis
Correct answer: C
Rationale: In this scenario, the client's presentation of coughing up rust-colored sputum, increased respiratory rate, expiratory grunting, and coarse crackles on lung auscultation suggests the development of pneumonia. Pneumonia is characterized by lung tissue inflammation or infection, often caused by various organisms. Symptoms may include productive cough, dyspnea, and abnormal breath sounds. Tuberculosis (Choice A) typically presents with a chronic cough, weight loss, and night sweats and is less likely in this acute post-operative setting. Pulmonary edema (Choice B) is characterized by pink, frothy sputum, crackles throughout the lungs, and typically occurs in the context of heart failure. Histoplasmosis (Choice D) is a fungal infection that usually presents with flu-like symptoms and is less likely to manifest with the specific respiratory findings described in this case.
4. The nurse reviews the record of a newborn infant and notes that a diagnosis of esophageal atresia with tracheoesophageal fistula is suspected. The nurse expects to note which most likely sign of this condition documented in the record?
- A. Incessant crying
- B. Coughing at nighttime
- C. Choking with feedings
- D. Severe projectile vomiting
Correct answer: C
Rationale: In esophageal atresia and tracheoesophageal fistula, the esophagus ends before it reaches the stomach, forming a blind pouch, and there is an abnormal connection (fistula) with the trachea. Any child who exhibits the '3 Cs'"?coughing and choking with feedings and unexplained cyanosis"?should be suspected to have tracheoesophageal fistula. Option A, 'Incessant crying,' is not a typical sign of esophageal atresia with tracheoesophageal fistula. Option B, 'Coughing at nighttime,' is not a specific sign associated with this condition. Option D, 'Severe projectile vomiting,' is not a common sign of esophageal atresia with tracheoesophageal fistula.
5. The nurse is providing discharge instructions to the mother of a child who had a cleft palate repair. Which statement should the nurse make to the mother?
- A. You should use an orthodontic nipple on the child's bottle.
- B. You need to use a plastic spoon to feed the child.
- C. You can allow the child to use a pacifier but only for 30 minutes at a time.
- D. You need to monitor the child's temperature for signs of infection using an oral thermometer.
Correct answer: A
Rationale: After a cleft palate repair, it is crucial to use an orthodontic nipple on the child's bottle to feed them appropriately. The mother should be instructed to give the child baby food or baby food mixed with water. It is important to avoid introducing straws, pacifiers, spoons, or fingers into the child's mouth for 7 to 10 days post-surgery to prevent complications. The use of a pacifier should be avoided for at least 2 weeks following the surgical repair to promote proper healing. Additionally, taking oral temperatures should be avoided, and alternative temperature monitoring methods should be utilized to reduce the risk of infection. Therefore, options B, C, and D are incorrect because they could potentially lead to complications or hinder the child's recovery after cleft palate repair.
