NCLEX RN Exam Review Answers
1. Mr. C is brought to the hospital with severe burns over 45% of his body. His heart rate is 124 bpm and thready, BP 84/46, respirations 24/minute and shallow. He is apprehensive and restless. Which of the following types of shock is Mr. C at highest risk for?
- A. Septic shock
- B. Hypovolemic shock
- C. Neurogenic shock
- D. Cardiogenic shock
Correct answer: B
Rationale: Mr. C, who has severe burns over 45% of his body, is at highest risk for hypovolemic shock. Burns lead to a loss of plasma volume, reducing the circulating fluid volume and impairing perfusion to vital organs and extremities. In this scenario, the signs of shock, such as increased heart rate, low blood pressure, shallow respirations, and restlessness, indicate a state of hypovolemic shock due to significant fluid loss. Septic shock (choice A) is primarily caused by severe infections, neurogenic shock (choice C) results from spinal cord injuries, and cardiogenic shock (choice D) stems from heart failure. However, in this case, the presentation aligns most closely with hypovolemic shock due to the extensive burn injury and its effects on fluid volume and perfusion.
2. To prepare a 56-year-old male patient with ascites for paracentesis, the nurse should?
- A. place the patient on NPO status.
- B. assist the patient to lie flat in bed.
- C. ask the patient to empty the bladder.
- D. position the patient on the right side.
Correct answer: C
Rationale: To prepare a patient with ascites for paracentesis, the nurse should ask the patient to empty the bladder. This is important to decrease the risk of bladder perforation during the procedure. The patient should be positioned in Fowler's position to facilitate the procedure, not lie flat in bed, which can compromise breathing. Placing the patient on NPO status is unnecessary as sedation is not typically required for paracentesis. Positioning the patient on the right side is not a standard preparatory measure for paracentesis.
3. Which of these individuals would the nurse suspect as having the greatest risk of contracting Hepatitis B?
- A. A sexually active 45-year-old man who has Type 1 Diabetes
- B. A 75-year-old woman who lives in a crowded nursing home
- C. A child who lives in a country with poor sanitation and hygiene standards
- D. A sexually active 23-year-old man who works in a hospital
Correct answer: D
Rationale: The correct answer is a sexually active 23-year-old man who works in a hospital. This individual is at the highest risk of contracting Hepatitis B due to exposure in a healthcare setting where potential bloodborne pathogens are present. Being sexually active also increases the risk of transmission through sexual contact. Choice A, a 45-year-old man with Type 1 Diabetes, is not directly associated with an increased risk of Hepatitis B. Choice B, a 75-year-old woman living in a crowded nursing home, is at risk for other infections due to the living environment but not specifically for Hepatitis B. Choice C, a child in a country with poor sanitation, is more at risk for water or foodborne illnesses rather than Hepatitis B transmission.
4. A 49-year-old female patient with cirrhosis and esophageal varices has a new prescription for propranolol (Inderal). Which finding is the best indicator that the medication has been effective?
- A. The patient reports no chest pain.
- B. Blood pressure is 140/90 mm Hg
- C. Stools test negative for occult blood.
- D. The apical pulse rate is 68 beats/minute.
Correct answer: C
Rationale: The best indicator that propranolol has been effective in a patient with cirrhosis and esophageal varices is when the stools test negative for occult blood. Propranolol is prescribed to decrease the risk of bleeding from esophageal varices. This medication's effectiveness is primarily assessed by the absence of blood in the stools, indicating a reduction in the risk of bleeding from the varices. Monitoring for chest pain, blood pressure control, and a decrease in heart rate are important parameters in other conditions treated with propranolol, such as hypertension, angina, and tachycardia, but in this particular case, the absence of occult blood in the stools is the most relevant indicator of treatment success.
5. A patient admitted to the hospital with myocardial infarction develops severe pulmonary edema. Which of the following symptoms should the nurse expect the patient to exhibit?
- A. Slow, deep respirations
- B. Stridor
- C. Bradycardia
- D. Air hunger
Correct answer: D
Rationale: In a patient with pulmonary edema following a myocardial infarction, the nurse should expect symptoms such as air hunger, anxiety, and agitation. Air hunger refers to the feeling of needing to breathe more deeply or more often. Other symptoms of pulmonary edema can include coughing up blood or bloody froth, orthopnea (difficulty breathing when lying down), and paroxysmal nocturnal dyspnea (sudden awakening with shortness of breath). Slow, deep respirations (Choice A) are not typical in pulmonary edema; these patients often exhibit rapid, shallow breathing due to the difficulty in oxygen exchange. Stridor (Choice B) is a high-pitched breathing sound often associated with upper airway obstruction, not typically seen in pulmonary edema. Bradycardia (Choice C), a slow heart rate, is not a characteristic symptom of pulmonary edema, which is more likely to be associated with tachycardia due to the body's compensatory response to hypoxia and increased workload on the heart.
