ATI NCLEX-RN Practice Questions Questions
Extract:
Question 1 of 5
Which of the following signs and symptoms indicates a tension pneumothorax as compared to an open pneumothorax?
Correct Answer: C
Rationale: The tension pneumothorax acts like a one-way valve so that the pneumothorax increases with each breath. Eventually, it occupies enough space to shift mediastinal tissue toward the unaffected side away from the midline. Tracheal deviation, movement of point of maximum impulse, and decreased cardiac output will occur. The other three options will occur in both types of pneumothorax.
Question 2 of 5
The physician has prescribed Coumadin (sodium warfarin) for a client having transient ischemic attacks. Which laboratory test measures the therapeutic level of Coumadin?
Correct Answer: A
Rationale: Prothrombin time (PT/INR) measures Coumadin's anticoagulant effect by assessing clotting time. PTT monitors heparin, and clot retraction or bleeding time are unrelated.
Question 3 of 5
At 30 weeks' gestation, a client is admitted to the unit in premature labor. Her physician orders that an IV be started with 500 mL D5W mixed with 150 mg of ritodrine stat. The RN prepares the IV solution with the medication. The RN knows that clients receiving the medication ritodrine IV should be observed closely for which one of the following side effects:
Correct Answer: C
Rationale: Ritodrine is a sympathomimetic β2-adrenergic agonist that can cause vasodilation, leading to hypotension. The body compensates by increasing heart rate, resulting in tachycardia.
Question 4 of 5
The nurse is caring for a client with a history of angina. Which medication should the nurse anticipate being prescribed for acute chest pain?
Correct Answer: A
Rationale: Nitroglycerin is used for acute angina relief by dilating coronary arteries. Metoprolol, amlodipine, and losartan are for long-term management, not acute pain.
Question 5 of 5
The nurse is assessing and getting a history from a client treated for depression with a monoamine oxidase (MAO) antidepressant. The most serious side effect associated with this antidepressant and the ingestion of tyramine in aged foods may be:
Correct Answer: A
Rationale: The most serious adverse reactions of MAO inhibitors involve blood pressure and ingestion of tyramine-containing foods, which may provoke a hypertensive crisis. MAO inhibitors cause adverse reactions affecting the central nervous system and serious adverse reactions involving blood pressure. MAO inhibitors affect neurotransmitters and may produce hypotensive reactions, but hypertensive crisis is the primary concern with tyramine. Gastrointestinal side effects may occur, but they are not the most serious adverse reactions.
