HESI Pharmacology Practice Exam
1. A health care provider (HCP) writes a prescription for digoxin (Lanoxin), 0.25 mg daily. The nurse teaches the client about the medication and tells the client that it is important to:
- A. Count the radial and carotid pulses every morning.
- B. Check the blood pressure every morning and evening.
- C. Stop taking the medication if the pulse is higher than 100 beats per minute.
- D. Withhold the medication and call the HCP if the pulse is less than 60 beats per minute.
Correct answer: D
Rationale: When taking digoxin, monitoring the pulse rate is essential due to its potential effects on heart rate. Digoxin can lead to bradycardia, where the pulse rate drops significantly. Withholding the medication and promptly contacting the healthcare provider if the pulse falls below 60 beats per minute is crucial to prevent severe complications and ensure appropriate management. Choices A, B, and C are incorrect because counting radial and carotid pulses, checking blood pressure, or stopping the medication based on a pulse rate higher than 100 beats per minute are not the primary monitoring parameters for a client taking digoxin.
2. A client is on nicotinic acid (niacin) for hyperlipidemia and the nurse provides instructions to the client about the medication. Which statement by the client would indicate an understanding of the instructions?
- A. It is not necessary to avoid the use of alcohol.
- B. The medication should be taken with meals to decrease flushing.
- C. Clay-colored stools are a common side effect and should not be of concern.
- D. Ibuprofen (Motrin) taken 30 minutes before the nicotinic acid should decrease the flushing.
Correct answer: D
Rationale: Aspirin or a nonsteroidal anti-inflammatory drug can be taken 30 minutes before taking the medication to decrease flushing. Alcohol consumption needs to be avoided because it will enhance this side effect. The medication should be taken with meals, this will decrease gastrointestinal upset. Taking the medication with meals has no effect on the flushing. Clay-colored stools are a sign of hepatic dysfunction and should be immediately reported to the health care provider (HCP).
3. A child is hospitalized with a diagnosis of lead poisoning. The healthcare provider assisting in caring for the child would prepare to assist in administering which of the following medications?
- A. Activated charcoal
- B. Sodium bicarbonate
- C. Syrup of ipecac
- D. Dimercaprol (BAL in Oil)
Correct answer: D
Rationale: Dimercaprol (BAL in Oil) is a chelating agent indicated for lead poisoning. It works by binding to lead and facilitating its removal from the body. Activated charcoal is used for certain types of poisoning by adsorbing toxins, while sodium bicarbonate can be used to treat acidosis. Syrup of ipecac is no longer recommended for poison treatment due to potential risks.
4. A nurse is providing instructions to an adolescent who has a history of seizures and is taking an anticonvulsant medication. Which of the following statements indicates that the client understands the instructions?
- A. I will never be able to drive a car.
- B. My anticonvulsant medication will clear up my skin.
- C. I can't drink alcohol while I am taking my medication.
- D. If I forget my morning medication, I can take two pills at bedtime.
Correct answer: C
Rationale: The correct answer is C: 'I can't drink alcohol while I am taking my medication.' Alcohol can lower the seizure threshold and should be avoided by individuals taking anticonvulsants. Choice A is incorrect because it is an extreme statement and not necessary for someone taking anticonvulsants. Choice B is incorrect as anticonvulsant medications are not used to clear skin conditions. Choice D is incorrect because doubling up medication doses can be harmful and should not be done without healthcare provider approval.
5. A client is prescribed phenytoin (Dilantin) for seizure control. Which statement by the client indicates an understanding of the medication?
- A. I should brush and floss my teeth regularly.
- B. I should take the medication with antacids.
- C. I can stop taking the medication once my seizures are controlled.
- D. I should avoid drinking milk while taking this medication.
Correct answer: A
Rationale: The correct statement is 'I should brush and floss my teeth regularly.' Phenytoin (Dilantin) can cause gingival hyperplasia, so maintaining good oral hygiene is essential. Taking the medication with antacids can affect its absorption, so it should not be done. It is crucial not to stop taking the medication abruptly, even if seizures are controlled. There is no specific requirement to avoid milk while taking phenytoin (Dilantin).
