ATI Med Surg Quiz 1 Questions
Extract:
Question 1 of 5
A nurse is monitoring a client who is on telemetry. Which of the following findings on the ECG strip should the nurse recognize as normal sinus rhythm?
Correct Answer: C
Rationale: A QRS duration of 0.06-0.10 seconds is normal and suggests normal conduction through the ventricles in normal sinus rhythm. The P wave should come before the QRS complex, a PR interval >0.20 seconds suggests first-degree AV block, and an inverted T wave suggests myocardial ischemia.
Question 2 of 5
A client seen in the clinic is directed to bring a sputum specimen back for an acid-fast bacillus (AFB) test in order to rule out tuberculosis. What direction will the nurse give the client regarding the collection of the specimen?
Correct Answer: B
Rationale: Morning sputum samples have higher bacterial concentrations, improving AFB test accuracy. A is premature, C is incorrect as multiple specimens are needed, and D is wrong as cultures take weeks.
Question 3 of 5
Which of the following would be an appropriate expected outcome of antibiotic treatment for an elderly client recovering from pneumonia?
Correct Answer: C
Rationale: Decreased consolidation on chest X-ray indicates resolving pneumonia, a key outcome of antibiotic treatment. A suggests worsening infection, B indicates respiratory distress, and D is undesirable.
Question 4 of 5
The nurse is checking a coworker's tuberculosis (TB) skin test. The forearm has a raised red area about 12 mm in diameter after 72 hours. What is the best interpretation of this skin test?
Correct Answer: A
Rationale: A 12 mm induration after 72 hours indicates TB exposure, a positive result. B requires further testing, C is unlikely, and D is incorrect as the reaction is positive.
Question 5 of 5
The nurse receives a new client from the emergency department with an order for propranolol (Inderal). Upon looking at the client's history, which diagnosis would make the nurse clarify this order?
Correct Answer: B
Rationale: Propranolol is a nonselective beta-blocker that can cause bronchoconstriction in asthma, leading to respiratory distress. It is not contraindicated in kidney failure (though caution is needed), and it is used to treat hypertension and tachycardia.
