Pharmacology HESI 55 Questions 2023
1. A client with a history of hypertension is prescribed hydrochlorothiazide. The practical nurse should monitor the client for which potential adverse effect?
- A. Hyperkalemia
- B. Hypokalemia
- C. Hypernatremia
- D. Hyponatremia
Correct answer: B
Rationale: Corrected Rationale: Hydrochlorothiazide is a diuretic that can lead to potassium loss, resulting in hypokalemia. Monitoring for hypokalemia is essential because it can cause various complications such as cardiac dysrhythmias. Therefore, the practical nurse should closely watch for signs and symptoms of low potassium levels in clients taking hydrochlorothiazide. Incorrect Rationale for Other Choices: A. Hyperkalemia is not typically associated with hydrochlorothiazide use; instead, it is more commonly linked to medications like ACE inhibitors or potassium-sparing diuretics. C. Hypernatremia is unlikely with hydrochlorothiazide use as it tends to cause sodium loss. D. Hyponatremia is more commonly associated with conditions where there is excessive water intake or syndrome of inappropriate antidiuretic hormone secretion (SIADH), rather than with hydrochlorothiazide use.
2. What information should the practical nurse provide to a female client who started taking an oral sulfonamide for a urinary tract infection the previous day and reports slight anorexia, while also experiencing urinary frequency?
- A. Take the medication with an antacid instead of cranberry juice to reduce the anorexia.
- B. Continue to take the medication with a sip of cranberry juice, restricting fluids until the frequency is controlled.
- C. Continue to drink cranberry juice, but take the medicine on an empty stomach with a full glass of water.
- D. Take the medication with a spoonful of ice cream or applesauce and avoid drinking cranberry juice.
Correct answer: C
Rationale: The practical nurse should advise the client to take sulfonamides with a full glass of water to help prevent crystalluria. It is essential to take the medication on an empty stomach, ideally 1 hour before eating or 2 hours after eating to maximize its absorption and effectiveness. Continuing to drink cranberry juice is beneficial, but it is important to take the medicine separately to enhance its therapeutic action.
3. A client with a diagnosis of generalized anxiety disorder is prescribed venlafaxine. The nurse should instruct the client that this medication may have which potential side effect?
- A. Nausea
- B. Dry mouth
- C. Insomnia
- D. Headache
Correct answer: A
Rationale: The correct answer is A: Nausea. Venlafaxine, a medication used for generalized anxiety disorder, can commonly cause nausea as a side effect. It is essential for clients to be aware of this potential side effect and advised to take the medication with food if nausea occurs. Choices B, C, and D are incorrect because dry mouth, insomnia, and headache are less commonly associated side effects of venlafaxine compared to nausea.
4. The practical nurse administered carbidopa-levodopa to a client diagnosed with Parkinson's disease. Which outcome by the client would indicate a therapeutic response?
- A. Decreased blood pressure
- B. Lessening of tremors
- C. Increased salivation
- D. Increased attention span
Correct answer: B
Rationale: The correct answer is B: Lessening of tremors. Carbidopa-levodopa increases the amount of levodopa to the CNS, providing more dopamine to the brain. Increased dopamine levels help alleviate Parkinson's symptoms such as tremors, involuntary movements, and gait abnormalities. Choices A, C, and D are incorrect as carbidopa-levodopa is not expected to have a direct effect on blood pressure, salivation, or attention span in the context of treating Parkinson's disease.
5. A client with diabetes mellitus type 2 is prescribed glipizide. What instruction should the nurse include in the client's teaching plan?
- A. Take this medication with meals.
- B. Avoid alcohol while taking this medication.
- C. Take this medication on an empty stomach.
- D. Report any signs of hypoglycemia to the healthcare provider.
Correct answer: A
Rationale: The correct instruction for a client prescribed glipizide, a sulfonylurea used to lower blood sugar levels, is to take the medication with meals. Taking it with meals helps to minimize the risk of hypoglycemia by ensuring a more balanced effect on blood glucose levels throughout the day. It is important for the client to follow this instruction to maintain stable blood sugar levels and reduce the likelihood of experiencing low blood sugar (hypoglycemia) episodes. Choice B is incorrect because there are no specific contraindications between glipizide and alcohol. Choice C is incorrect as glipizide should not be taken on an empty stomach. Choice D is incorrect as while it is important to report signs of hypoglycemia, the primary focus should be on preventing hypoglycemia by taking the medication with meals.
