Exam Cram NCLEX RN Practice Questions
1. The physician has decided to perform a thoracentesis based on Mr. R's assessment. Which of the following actions from the nurse is most appropriate?
- A. Instruct the client not to talk during the procedure
- B. Assist the client to sit upright or slightly lean forward
- C. Insert a 20-gauge needle just above the 4th intercostal space
- D. Connect the needle to suction to remove fluid that has collected in the pleural space
Correct answer: A
Rationale: The correct answer is to instruct the client not to talk during the procedure. This is important to prevent air from being drawn into the pleural space during the thoracentesis. Choice B is incorrect because the client should be sitting upright or slightly leaning forward during the procedure to facilitate access to the pleural space. Choice C is incorrect as the nurse should not perform the thoracentesis procedure, which involves inserting a needle into the pleural space - this is the physician's responsibility. Choice D is incorrect as connecting the needle to suction to remove fluid is not the appropriate procedure for a thoracentesis. Thoracentesis is typically done to remove fluid or air for diagnostic or therapeutic purposes, not to connect to suction to remove fluid that has collected in the pleural space.
2. What drives respiration in a patient with advanced chronic respiratory failure?
- A. Hypoxemia
- B. Hypocapnia
- C. Hypercapnia
- D. None of the above
Correct answer: A
Rationale: In patients with advanced chronic respiratory failure, such as those with chronic obstructive pulmonary disease (COPD), the respiratory drive shifts from being primarily stimulated by high levels of carbon dioxide (hypercapnia) to being driven by low oxygen levels (hypoxemia). This shift is due to the body's adaptation to chronic respiratory acidosis and hypoxemia. As a result, hypoxemia becomes the primary stimulus for respiration in these patients. Hypocapnia, a low level of carbon dioxide, is not a common driver of respiration in patients with advanced chronic respiratory failure. Therefore, the correct answer is hypoxemia.
3. When analyzing the results of the urinalysis collected preoperatively from a child with epispadias scheduled for surgical repair, which finding should the nurse most likely expect to note?
- A. Hematuria
- B. Proteinuria
- C. Bacteriuria
- D. Glucosuria
Correct answer: C
Rationale: Epispadias is a congenital defect characterized by the abnormal placement of the urethral orifice of the penis, often on the dorsum. This anatomical anomaly predisposes individuals to bacterial entry into the urinary tract, leading to bacteriuria. Hematuria, proteinuria, and glucosuria are not typically associated with epispadias. Hematuria refers to the presence of blood in the urine, proteinuria indicates protein in the urine, and glucosuria is the presence of glucose in the urine, none of which are commonly seen in epispadias.
4. 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.
5. What would be the most appropriate follow-up by the home care nurse for a 57-year-old male client with a hemoglobin of 10 g/dl and a hematocrit of 32%?
- A. Ask the client if he has noticed any bleeding or dark stools
- B. Tell the client to call 911 and go to the emergency department immediately
- C. Schedule a repeat Hemoglobin and Hematocrit in 1 month
- D. Tell the client to schedule an appointment with a hematologist
Correct answer: A
Rationale: The correct answer is to ask the client if he has noticed any bleeding or dark stools. Normal hemoglobin for males is 13.0 - 18 g/dl, and normal hematocrit for males is 42 - 52%. The values of hemoglobin and hematocrit provided for the client are below normal, indicating mild anemia. The first step for the nurse is to inquire about any signs of bleeding or changes in stools that could suggest bleeding from the gastrointestinal tract. This helps in assessing the possible cause of the low hemoglobin and hematocrit levels. The other options are not appropriate as calling 911 and going to the emergency department immediately is not warranted for mild anemia, scheduling a repeat test in 1 month delays addressing the current concern, and referring the client to a hematologist may be premature without investigating the cause of the low levels first.
