RN NCLEX Practice Test
Question 1 of 5.
To appropriately monitor therapy and client progress, the nurse should be aware that increased myocardial work and O2 demand will occur with which of the following?
A. Positive inotropic therapy
B. Negative chronotropic therapy
C. Increase in balance of myocardial O2 supply and demand
D. Afterload reduction therapy
Explanation: Inotropic therapy will increase contractility, which will increase myocardial O2 demand. Decreased heart rate to the point of bradycardia will increase coronary artery filling time. This should be used cautiously because tachycardia may be a compensatory mechanism to increase cardiac output. The goal in the care of the MI client with angina is to maintain a balance between myocardial O2 supply and demand. Decrease in systemic vascular resistance by drug therapy, such as IV nitroglycerin or nitroprusside, or intra-aortic balloon pump therapy, would decrease myocardial work and O2 demand.
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.
