Pharmacology HESI 55 Questions 2023
1. What is the primary nursing intervention that the practical nurse should perform before administering ampicillin to a client diagnosed with a urinary tract infection?
- A. Obtain a clean-catch urine specimen.
- B. Assess the urine pH for acidity.
- C. Insert an indwelling catheter.
- D. Assess for complaints of dysuria.
Correct answer: A
Rationale: The correct answer is to obtain a clean-catch urine specimen. Before administering ampicillin to a client with a urinary tract infection, it is crucial to collect a urine specimen to determine the causative organism and evaluate the effectiveness of pharmacological therapy. Assessing the urine pH for acidity (choice B) is not the primary intervention needed before administering ampicillin. Inserting an indwelling catheter (choice C) is invasive and not necessary unless indicated for specific reasons. Assessing for complaints of dysuria (choice D) is important but does not take precedence over obtaining a urine specimen for proper diagnosis and treatment.
2. A client with a diagnosis of schizophrenia is prescribed olanzapine. The nurse should monitor for which potential side effect?
- A. Weight gain
- B. Insomnia
- C. Dry mouth
- D. Headache
Correct answer: A
Rationale: When a client with schizophrenia is prescribed olanzapine, the nurse should monitor for weight gain as a potential side effect. Olanzapine is known to cause metabolic changes that can lead to weight gain, making it crucial for the nurse to closely monitor the client's weight during treatment. This side effect is significant as it can impact the client's overall health and well-being, so early detection and intervention are essential to manage it effectively.
3. A client with asthma is prescribed fluticasone. The nurse should instruct the client to use this medication at which time?
- A. During an asthma attack
- B. Twice a day
- C. Once a day
- D. At night before bed
Correct answer: C
Rationale: Fluticasone is a maintenance medication for asthma aimed at controlling symptoms. It should be taken once a day on a regular basis to provide ongoing relief and prevent asthma symptoms, rather than being used to treat acute asthma attacks. Therefore, the correct answer is to use it once a day. Choices A, B, and D are incorrect because using fluticasone during an asthma attack, twice a day, or only at night before bed does not align with the medication's purpose of being a daily maintenance therapy.
4. A client with schizophrenia is prescribed risperidone. Which statement by the client indicates the need for further teaching?
- A. I can stop taking this medication once I feel better.
- B. This medication may cause drowsiness.
- C. This medication might make me feel drowsy.
- D. I should avoid alcohol while taking this medication.
Correct answer: A
Rationale: Clients should not stop taking risperidone abruptly once they feel better without consulting their healthcare provider.
5. A client has been diagnosed with open-angle glaucoma. The healthcare provider prescribes pilocarpine 1% eye drops. The nurse explains that which action of this drug makes it a useful treatment for the client's condition?
- A. The ciliary muscle contracts, increasing the outflow of aqueous humor in the eye.
- B. Ciliary muscles are paralyzed to decrease accommodation.
- C. Bilateral mydriasis with cycloplegia is accomplished.
- D. The production of aqueous humor in the eyes is decreased.
Correct answer: A
Rationale: Pilocarpine, a cholinergic agent, stimulates the ciliary muscle to contract, which opens the trabecular meshwork and facilitates the outflow of aqueous humor, reducing intraocular pressure. This mechanism helps in managing open-angle glaucoma by improving drainage and lowering pressure within the eye. Choice A is correct because the contraction of the ciliary muscle increases the outflow of aqueous humor, aiding in the treatment of open-angle glaucoma. Choices B, C, and D are incorrect because they do not describe the mechanism of action of pilocarpine in treating glaucoma.
