For a patient with asthma, what is the primary purpose of prescribing montelukast?
- A. Relieve acute bronchospasm
- B. Prevent asthma attacks
- C. Thin respiratory secretions
- D. Suppress cough
Correct Answer: B
Rationale: The primary purpose of prescribing montelukast for a patient with asthma is to prevent asthma attacks. Montelukast is a leukotriene receptor antagonist that helps to reduce inflammation in the airways, thereby preventing asthma symptoms and attacks. It is not used to relieve acute bronchospasm (Choice A), as it is not a fast-acting rescue medication like a bronchodilator. Montelukast also does not thin respiratory secretions (Choice C) or suppress cough (Choice D) as its main mechanism of action is to prevent and control asthma symptoms by inhibiting leukotrienes.

A young adult female client is seen in the emergency department for a minor injury following a motor vehicle collision. She states she is very angry at the person who hit her car. What is the best nursing response?
- A. You are lucky to be alive. Be grateful no one was killed.'
- B. I understand your car was not seriously damaged.'
- C. You are upset that this incident has brought you here.'
- D. Have you ever been in the emergency department before?'
Correct Answer: C
Rationale: The correct answer is C: "You are upset that this incident has brought you here." This response acknowledges the client's feelings of anger and validates her emotions, showing empathy and understanding. It demonstrates active listening and therapeutic communication, which is crucial in building trust and rapport with the client.
Choice A is incorrect as it dismisses the client's feelings of anger and invalidates her emotions by shifting the focus to being grateful instead. Choice B is incorrect as it minimizes the client's emotional response by focusing on the material aspect of the situation rather than addressing her feelings. Choice D is incorrect as it does not address the client's emotional state and is a closed-ended question that does not encourage further discussion or exploration of the client's feelings.
A patient with rheumatoid arthritis is prescribed methotrexate. What is an important teaching point for the nurse to provide?
- A. Take folic acid supplements as prescribed.
- B. Avoid alcohol completely.
- C. Expect to see immediate results.
- D. Limit fluid intake to 1 liter per day.
Correct Answer: A
Rationale: The correct answer is A: Take folic acid supplements as prescribed. Methotrexate can lead to folic acid deficiency, causing side effects. Supplementing with folic acid can help manage these side effects. It is crucial for the nurse to emphasize the importance of taking folic acid as prescribed to prevent adverse effects.
Summary of Incorrect Choices:
B: Avoid alcohol completely - While alcohol should be limited or avoided due to potential liver toxicity with methotrexate, complete avoidance may not be necessary for all patients.
C: Expect to see immediate results - Methotrexate takes time to work, and patients should not expect immediate results. Patience is necessary.
D: Limit fluid intake to 1 liter per day - There is no specific guideline to limit fluid intake with methotrexate. Adequate hydration is important for overall health.
Following a CVA, the nurse assesses that a client has developed dysphagia, hypoactive bowel sounds, and a firm, distended abdomen. Which prescription for the client should the nurse question?
- A. Continuous tube feeding at 65 ml/hr via gastrostomy.
- B. Total parenteral nutrition to be infused at 125 ml/hour.
- C. Nasogastric tube connected to low intermittent suction.
- D. Metoclopramide (Reglan) intermittent piggyback.
Correct Answer: A
Rationale: The correct answer is A: Continuous tube feeding at 65 ml/hr via gastrostomy. After a CVA, dysphagia, hypoactive bowel sounds, and a firm, distended abdomen indicate a risk for aspiration and bowel obstruction. Continuous tube feeding may worsen these issues. Option B provides nutrition intravenously, bypassing the gastrointestinal tract. Option C helps decompress the stomach. Option D is a medication to help with GI motility. Therefore, the nurse should question option A due to the risk of complications post-CVA.
What is the primary action of digoxin when prescribed to a patient with heart failure?
- A. Increase heart rate
- B. Decrease cardiac output
- C. Strengthen cardiac contractions
- D. Lower blood pressure
Correct Answer: C
Rationale: The primary action of digoxin in heart failure is to strengthen cardiac contractions. Digoxin inhibits the sodium-potassium pump, leading to an increase in intracellular calcium levels, which enhances the force of myocardial contractions. This helps improve cardiac output and symptoms of heart failure.
Explanation:
A: Incorrect - Digoxin does not increase heart rate, it mainly affects the strength of contractions.
B: Incorrect - Digoxin does not decrease cardiac output; it actually helps improve it by enhancing contractility.
D: Incorrect - Digoxin may have a slight effect on lowering blood pressure, but its primary action in heart failure is to strengthen cardiac contractions, not lower blood pressure.
What instruction should the nurse give regarding the administration of alendronate to a patient with osteoporosis?
- A. Take the medication with milk.
- B. Lie down for 30 minutes after taking the medication.
- C. Take the medication with a full glass of water.
- D. Take the medication before bedtime.
Correct Answer: C
Rationale: The correct answer is C: Take the medication with a full glass of water. Alendronate should be taken with a full glass of water on an empty stomach in the morning to enhance absorption. Option A is incorrect because taking alendronate with milk decreases its absorption. Option B is incorrect as lying down after taking alendronate can lead to esophageal irritation. Option D is incorrect because taking the medication before bedtime can cause esophageal irritation as well due to the risk of reflux when lying down.
