RN NCLEX Practice Test
Question 1 of 5.
A client has renal failure. Today's lab values indicate he has an elevated serum potassium. What additional priority information does the nurse need to obtain?
A. Evaluation of his level of consciousness
B. Evaluation of an electrocardiogram
C. Measurement of his urine output for the past 8 hours
D. Serum potassium lab values for the last several days
Explanation: The level of consciousness is not affected by elevated potassium levels. An electrocardiogram (EKG) can tell the nurse whether this client is experiencing any cardiac dysfunction or arrhythmias related to the elevated potassium level. Measurement of the urine output is not a priority nursing action at this time. The client's serum potassium values for the past several days may provide information about his renal function, but they are not a priority at this time.
Question 2 of 5.
The nurse is observing the ambulation of a client recently fitted for crutches. Which observation requires nursing intervention?
A. Two finger widths are noted between the axilla and the top of the crutch.
B. The client bears weight on his hands when ambulating.
C. The crutches and the client's feet move alternately.
D. The client bears weight on his axilla when standing.
Explanation: Bearing weight on the axilla can cause nerve damage (e.g., brachial plexus injury); crutches should support weight on the hands.
Question 3 of 5.
A client with angina is being discharged with a prescription for Transderm Nitro (nitroglycerin) patches. The nurse should tell the client to:
A. Shave the area before applying the patch
B. Remove the old patch and clean the skin with alcohol
C. Cover the patch with plastic wrap and tape it in place
D. Avoid cutting the patch because it will alter the dose
Explanation: Cutting a nitroglycerin patch can alter the dose by disrupting the drug delivery system, so clients should be instructed to avoid this.
Question 4 of 5.
A patient refuses to take his dose of oral medication. The nurse tells the patient that if he does not take the medication that she will administer it by injection. The nurse's comments can result in a charge of:
A. Malpractice
B. Assault
C. Negligence
D. Battery
Explanation: Threatening to administer medication by injection against the patient's will constitutes assault, as it involves a threat of unwanted contact.
Question 5 of 5.
An 18-month-old is admitted to the hospital with acute laryngotracheobronchitis. When assessing the respiratory status, the nurse should expect to find:
A. Inspiratory stridor and harsh cough
B. Strident cough and drooling
C. Wheezing and intercostal retractions
D. Expiratory wheezing and nonproductive cough
Explanation: Acute laryngotracheobronchitis (croup) typically presents with inspiratory stridor and a harsh, barking cough due to subglottic airway inflammation.
