Respiratory System NCLEX Questions Questions
Question 1 of 5
What is the purpose of treatment with amantadine (Symmetrel)?
Correct Answer: C
Rationale: Rationale: 1. Amantadine is an antiviral medication effective against type A influenza virus. 2. By taking it within 48 hours of exposure, it can lessen flu symptoms by inhibiting viral replication. 3. It does not prevent pneumonia or avian flu specifically. 4. It is not used for reducing bronchitis irritation. Summary: Amantadine is specifically used to reduce the severity of type A flu symptoms when taken within 48 hours of exposure. It is not for prevention of viral pneumonia, avian flu, or bronchitis irritation.
Question 2 of 5
When instructing the client with chronic stable angina it should be emphasized that angina may be brought on by many precipitating factors including the following:
Correct Answer: D
Rationale: Step 1: Consumption of a heavy meal can lead to increased blood flow to the digestive system, causing a temporary reduction in blood flow to the heart muscle. Step 2: This reduction can trigger angina symptoms in individuals with chronic stable angina. Step 3: Emphasizing this to the client helps in understanding potential triggers to manage their condition effectively. Step 4: Rest (A) is usually recommended to relieve angina, sudden change in position (B) is not a common trigger, and severe depression (C) can exacerbate angina but is not a direct precipitating factor like heavy meals.
Question 3 of 5
A client who is found unresponsive has the following arterial blood gases: pH 7.12, PCO2 90, and HCO3 26. The nurse interprets the results as indicating which condition?
Correct Answer: D
Rationale: The correct answer is D, respiratory acidosis without compensation. The low pH and high PCO2 levels indicate respiratory acidosis. HCO3 is within normal range, suggesting no metabolic compensation. This is not metabolic acidosis as the HCO3 level is not elevated. Not partial compensation as the HCO3 level is not compensating for the respiratory acidosis.
Question 4 of 5
All of the following states decrease lung compliance EXCEPT
Correct Answer: D
Rationale: The correct answer is D: Emphysema. Emphysema is characterized by destruction of lung tissue, leading to loss of elasticity and increased compliance. Increased compliance means the lungs are easier to expand, contrary to decreased compliance seen in the other conditions listed. Lung fibrosis, increased pulmonary venous pressure, and prolonged lung collapse all lead to decreased lung compliance by causing stiffness, fluid accumulation, and reduced lung expansion, respectively. Therefore, D is the correct answer as it does not decrease lung compliance.
Question 5 of 5
A male adult patient on mechanical ventilation is receiving pancuronium bromide (Pavulon), 0.01 mg/kg I.V. as needed. Which assessment finding indicates that the patient needs another pancuronium dose?
Correct Answer: D
Rationale: The correct answer is D: Fighting the ventilator. This indicates inadequate muscle relaxation, requiring another dose of pancuronium. Leg, finger, and lip movements are not reliable indicators of muscle relaxation in a mechanically ventilated patient. Fighting the ventilator suggests the patient is not adequately sedated or paralyzed, requiring further intervention to maintain optimal ventilation and oxygenation.
