1. When should Montelukast be taken?

A. At least two hours before exercise
B. Daily in the evening
C. Two hours before exercise or daily in the evening
D. None of the above

Correct answer: B

Rationale: Montelukast should be taken daily in the evening to effectively manage asthma symptoms. Taking it at the same time each day helps maintain a consistent level of the medication in the body, providing optimal control over asthma symptoms and inflammation. Choice A is incorrect because Montelukast should not be taken specifically before exercise, but rather daily. Choice C is incorrect because although taking Montelukast two hours before exercise is not necessary, taking it daily in the evening is essential for its effectiveness. Choice D is incorrect as Montelukast should be taken daily to manage asthma.

2. A healthcare provider plans to administer Morphine IV to a postoperative client. Which of the following actions should the provider take?

A. Monitor for seizures and confusion with repeated doses.
B. Protect the client's skin from severe diarrhea associated with morphine.
C. Withhold this medication if the respiratory rate is less than 12/min.
D. Administer Morphine intermittently via IV bolus over 30 seconds or less.

Correct answer: C

Rationale: The correct action for the provider is to withhold morphine if the client's respiratory rate is 12/min or less. Respiratory depression is a serious side effect of morphine and other opioids. Withholding the medication and informing the healthcare provider is essential to prevent further respiratory compromise in the client. Choices A, B, and D are incorrect because monitoring for seizures and confusion, protecting the client's skin from severe diarrhea, and administering morphine via IV bolus over 30 seconds or less are not the primary actions to ensure client safety when administering morphine IV. Respiratory status is crucial due to the risk of respiratory depression associated with opioid administration.

3. A client has a new prescription for erythromycin. Which of the following statements by the client indicates an understanding of the teaching?

A. I should take this medication with a full glass of water.
B. I should avoid direct sunlight while taking this medication.
C. I will take this medication on an empty stomach.
D. I should take an antacid 30 minutes before taking this medication.

Correct answer: C

Rationale: The correct answer is C. Erythromycin should be taken on an empty stomach with a full glass of water to increase absorption. Taking it with a full glass of water (Choice A) is incorrect. Avoiding direct sunlight (Choice B) is not related to erythromycin use. Taking an antacid before the medication (Choice D) can interfere with its absorption.

4. When teaching a client with a new prescription for nitroglycerin patches, which of the following instructions should the nurse include?

A. Apply the patch at the same time every day.
B. Rotate the application site daily.
C. Remove the patch for 12 hours each day.
D. Cut the patch in half if needed.

Correct answer: B

Rationale: The correct instruction for a client with a new prescription for nitroglycerin patches is to rotate the application site daily. This is important to prevent skin irritation and ensure optimal absorption of the medication. Applying the patch at the same time every day (Choice A) is not necessary for nitroglycerin patches. Removing the patch for 12 hours each day (Choice C) would disrupt the continuous delivery of medication. Cutting the patch in half (Choice D) can alter the dose and is not recommended unless directed by a healthcare provider.
