RN NCLEX Practice Test Questions
Extract:
Question 1 of 5
The nurse discovers that a 78-year-old client who received hydralazine (Apresoline) 20 mg 45 minutes ago has a blood pressure of 70/40 mm Hg. The client has been on this dose of the medication for 3 years. Which of the following data is most likely significant in relation to the cause of the low blood pressure?
Correct Answer: B
Rationale: (A,
D) Decreased pulse volume and increased pulse rate are signs of an acute hypotensive episode. Inadequate fluid volume when taking vasodilators can result in a drop in blood pressure when vasodilation starts to physiologically occur as an action of the drug. A potassium level of 3.3 would not be associated with a significant drop in blood pressure.
Question 2 of 5
Which diet would the nurse expect to see ordered for a patient with nephrotic syndrome?
Correct Answer: B
Rationale: Nephrotic syndrome causes proteinuria, leading to hypoalbuminemia. A moderate protein diet (0.8–1 g/kg/day) helps replace lost protein without overloading the kidneys. Low carbohydrate, low calcium, or increased potassium diets are not specific to nephrotic syndrome.
Question 3 of 5
The nurse knows that children are more susceptible to respiratory tract infections owing to physiological differences. These childhood differences, adverts an adult, include:
Correct Answer: D
Rationale: Although a child has fewer alveoli than an adult, the child's respiratory rate is faster. Although a child may use diaphragmatic breathing, the adult exchanges a larger volume of air. The adult has a larger number of alveoli than a child. The child's chest is rounded whereas the adult chest is more of an oval shape, and the child does exchange a smaller volume of air than an adult.
Question 4 of 5
A 42-year-old client on an inpatient psychiatric unit comments that he was brought to the hospital by his wife because he had taken too many pills and states, 'I just couldn't take it anymore.' The nurse's best response to this disclosure would be:
Correct Answer: B
Rationale: Disapproving gives the impression that the nurse has a right to pass judgment on the client's thoughts, actions, or ideas. Giving a broad opening gives the client encouragement to continue with verbalization. Failing to acknowledge the client's feelings conveys a lack of understanding and empathy. Changing the subject takes the conversation away from the client and is indicative of the nurse's anxiety or insensitivity.
Question 5 of 5
A client is admitted with symptoms of vertigo and syncope.
Correct Answer: C
Rationale: Left subclavian artery obstruction can cause subclavian steal syndrome, leading to vertigo, syncope, and radial pulse differences (>10 bpm) due to blood flow reversal. Memory loss (
A), numbness (
B), and headache (
D) are unrelated.
