A patient with peptic ulcer disease is prescribed omeprazole. When should the patient take this medication for optimal effectiveness?
- A. With meals
- B. At bedtime
- C. Before meals
- D. After meals
Correct Answer: C
Rationale: The correct answer is C: Before meals. Omeprazole is a proton pump inhibitor that works best when taken before meals to inhibit acid secretion before food intake. Taking it with meals (choice A) may decrease its effectiveness as it needs time to be absorbed. Taking it at bedtime (choice B) may not provide optimal coverage throughout the day. Taking it after meals (choice D) may not allow enough time for the medication to start working before the next meal.

A patient with glaucoma is prescribed timolol eye drops. What is the primary action of this medication?
- A. Reduce intraocular pressure
- B. Dilate the pupils
- C. Constrict the pupils
- D. Enhance tear production
Correct Answer: A
Rationale: The correct answer is A: Reduce intraocular pressure. Timolol is a beta-blocker that works by decreasing the production of aqueous humor in the eye, thereby reducing intraocular pressure. This action helps to prevent damage to the optic nerve in patients with glaucoma. Choices B and C are incorrect because timolol does not affect pupil size. Choice D is incorrect because timolol does not enhance tear production; in fact, it may have a drying effect on the eyes.

- A. Take the medication with food to enhance absorption.
- B. Do not crush or chew the capsules.
- C. Increase intake of green leafy vegetables.

2. Crushing or chewing the capsules can lead to an increased risk of bleeding due to rapid release of the medication.
3. Therefore, advising the patient not to crush or chew the capsules is crucial to ensure the safety and efficacy of dabigatran therapy.
Summary:
A: Taking with food is not necessary for dabigatran absorption.
C: Green leafy vegetables are high in vitamin K, which can interfere with anticoagulant therapy.
D: There is no need to avoid all dairy products while taking dabigatran.
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 chronic obstructive pulmonary disease (COPD) is prescribed tiotropium. What is the primary purpose of this medication?
- A. Reduce mucus production
- B. Relieve bronchospasm
- C. Suppress cough
- D. Thin respiratory secretions
Correct Answer: B
Rationale: The correct answer is B: Relieve bronchospasm. Tiotropium is an anticholinergic medication that acts by relaxing the muscles around the airways, thereby helping to relieve bronchospasm in patients with COPD. This results in improved airflow and reduced shortness of breath.
A: Reduce mucus production - This is incorrect as tiotropium does not directly affect mucus production but rather focuses on bronchospasm relief.
C: Suppress cough - Tiotropium may help with cough associated with COPD by improving airflow, but its primary purpose is not to suppress cough.
D: Thin respiratory secretions - Tiotropium does not have a direct effect on thinning respiratory secretions; its main action is bronchodilation to relieve bronchospasm in COPD.
A patient with epilepsy is prescribed phenytoin. What is the primary side effect the nurse should monitor for?
- A. Hypotension
- B. Gingival hyperplasia
- C. Bradycardia
- D. Hyperkalemia
Correct Answer: B
Rationale: The correct answer is B: Gingival hyperplasia. Phenytoin is known to cause gingival overgrowth as a side effect. This is due to its effect on fibroblasts in the gums, leading to increased connective tissue production. Hypotension (A), bradycardia (C), and hyperkalemia (D) are not common side effects of phenytoin. Monitoring for gingival hyperplasia is crucial to prevent complications such as difficulty in eating, speaking, and maintaining oral hygiene.
