HESI Pharmacology Practice Exam
1. When administering hydrochlorothiazide (HydroDIURIL) to a client, the nurse should be aware of which of the following concerns?
- A. Hypouricemia, hyperkalemia
- B. Increased risk of osteoporosis
- C. Hypokalemia, hyperglycemia, sulfa allergy
- D. Hyperkalemia, hypoglycemia, penicillin allergy
Correct answer: C
Rationale: The correct answer is C. Hydrochlorothiazide is a thiazide diuretic, which can lead to hypokalemia and hyperglycemia. It is also associated with hypercalcemia, hyperlipidemia, and hyperuricemia. Being a sulfa-based medication, individuals with a sulfa allergy are at risk for an allergic reaction when taking hydrochlorothiazide. Choice A is incorrect because hydrochlorothiazide can cause hyperkalemia rather than hypouricemia. Choice B is incorrect as there is no direct link between hydrochlorothiazide and an increased risk of osteoporosis. Choice D is incorrect because hypoglycemia and penicillin allergy are not typically associated with hydrochlorothiazide use.
2. The nurse is caring for several patients who are receiving antibiotics. Which order will the nurse question?
- A. Azithromycin (Zithromax) 500 mg IV in 500 mL of fluid
- B. Azithromycin (Zithromax) 500 mg PO once daily
- C. Erythromycin 300 mg IM QID
- D. Erythromycin 300 mg PO QID
Correct answer: C
Rationale: The nurse should question the order for Erythromycin 300 mg IM QID. Erythromycin and other macrolides should not be given intramuscularly because they cause painful tissue irritation. Options A and B are correct routes for Azithromycin, either intravenously or orally. Option D is a correct route for Erythromycin, which is orally.
3. A client is admitted with a diagnosis of schizophrenia. The client refuses to take medication and states 'I don't think I need those medications. They make me too sleepy and drowsy. I insist that you explain their use and side effects.' The nurse should understand that
- A. A referral is needed to the psychiatrist who is to provide the client with answers
- B. The client has a right to know about the prescribed medications
- C. Such education is an independent decision of the individual nurse whether or not to teach clients about their medications
- D. Clients with schizophrenia are at a higher risk of psychosocial complications when they know about their medication side effects
Correct answer: B
Rationale: The correct answer is B. The client has a legal right to be informed about their treatment, including medication uses and side effects, as part of informed consent. This helps ensure that the client can make an informed decision about their care. Choice A is incorrect because the nurse can provide the client with information about their medications. Choice C is incorrect as it is not an independent decision of the nurse but a professional responsibility to educate clients. Choice D is incorrect as knowledge about medication side effects can actually empower clients to manage their condition effectively.
4. A client with a history of coronary artery disease (CAD) is admitted with chest pain. Which diagnostic test should the nurse anticipate preparing the client for first?
- A. Electrocardiogram (ECG)
- B. Chest X-ray
- C. Arterial blood gases (ABGs)
- D. Echocardiogram
Correct answer: A
Rationale: The correct answer is A: Electrocardiogram (ECG). An electrocardiogram should be performed first to assess for cardiac ischemia in a client with a history of CAD and chest pain. An ECG provides immediate information about the heart's electrical activity, helping to identify signs of ischemia or a heart attack. While other diagnostic tests like chest X-ray, arterial blood gases, and echocardiogram may also be necessary in the evaluation of chest pain, they do not provide the initial direct assessment of cardiac ischemia that an ECG does.
5. A male client with cancer who has lost 10 pounds during the last months tells the nurse that beef, chicken, and eggs, which used to be his favorite foods, now taste 'bitter'. He complains that he simply has no appetite. What action should the nurse implement?
- A. Suggest the use of alternative sources of protein such as dairy products and nuts.
- B. Encourage the client to eat smaller, more frequent meals.
- C. Offer nutritional supplements between meals.
- D. Discuss the possibility of appetite stimulants with the healthcare provider.
Correct answer: A
Rationale: Offering alternative protein sources like dairy products and nuts can help maintain nutrition when the client finds certain foods unpalatable, as in this case where beef, chicken, and eggs taste 'bitter'. Encouraging smaller, more frequent meals may not address the issue of unpalatable foods. Offering nutritional supplements between meals may not specifically address the problem of protein intake. Discussing appetite stimulants should be considered after exploring less invasive options first.
