NCLEX-RN Exam Practice Questions
Extract:
Question 1 of 5
A client diagnosed with severe anemia is to receive 2 U of packed red blood cells. Prior to starting the blood transfusion, the nurse must:
Correct Answer: A
Rationale: A baseline set of vital signs is necessary to determine if any transfusion reactions occur as the blood product is being administered. The only companion fluid to be used during a blood transfusion is normal saline. The calcium in Ringer's lactate can cause clotting. Only a blood administration set should be used. A microdrip tube would cause lysis of the red blood cells. Proper identification of the recipient and the blood product must be validated by at least two people.
Question 2 of 5
The client is scheduled for a cardiac CTA. Prior to the cardiac CTA, the nurse should do which of the following?
Correct Answer: A, B, C
Rationale: Cardiac CTA involves contrast dye, so checking creatinine (
A) assesses kidney function to prevent contrast-induced nephropathy. Shellfish allergies (
B) may indicate iodine sensitivity. Consent (
C) is required for invasive procedures. Hearing issues (
D) and water intake (E) are less critical.
Question 3 of 5
The nurse is assessing a client with suspected hypovolemic shock. Which finding is most indicative?
Correct Answer: A
Rationale: Tachycardia is a hallmark of hypovolemic shock, compensating for reduced blood volume. Hypothermia (
B) is secondary, bradypnea (
C) is atypical, and hypertension (
D) is not associated.
Question 4 of 5
The nurse is caring for a client with a nasogastric tube for decompression. Which action is most appropriate to ensure proper function?
Correct Answer: C
Rationale: Checking nasogastric tube placement (e.g., via pH or aspiration) before feedings or medications ensures the tube is in the stomach, preventing aspiration. Irrigation frequency depends on protocol, clamping may cause reflux, and supine positioning risks aspiration.
Question 5 of 5
Which of the following factors affects the accuracy of pulse oximetry readings?
Correct Answer: A, B, C
Rationale: Pulse oximetry accuracy is reduced by poor circulation (
A), improper probe placement (
B), and bright lighting (
C). Dark skin (
D) has minimal impact with modern sensors.
