Pharmacology HESI Quizlet
1. A healthcare professional is preparing to administer digoxin (Lanoxin), 0.125 mg orally, to a client with heart failure. Which vital sign is most important for the healthcare professional to check before administering the medication?
- A. Heart rate
- B. Temperature
- C. Respirations
- D. Blood pressure
Correct answer: A
Rationale: Before administering digoxin, it is essential to assess the client's heart rate as this medication directly affects cardiac function. Monitoring the heart rate helps identify if it is within the acceptable range for administering digoxin. A pulse rate below 60 beats per minute warrants withholding the medication to prevent potential adverse effects like bradycardia or cardiac arrhythmias.
2. 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.
3. A client has been prescribed cyclosporine (Sandimmune). Which food item should the client avoid based on the medication's interaction?
- A. Red meats
- B. Orange juice
- C. Grapefruit juice
- D. Green, leafy vegetables
Correct answer: C
Rationale: Grapefruit juice should be avoided when taking cyclosporine because it inhibits the metabolism of the medication, leading to increased blood levels and a higher risk of toxicity. It is important for the client to follow this dietary instruction to ensure the safe and effective use of cyclosporine.
4. 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.
5. While taking trimethoprim-sulfamethoxazole (TMP-SMZ), a client should be instructed to report which symptom if it develops during the course of this medication therapy?
- A. Nausea
- B. Diarrhea
- C. Headache
- D. Sore throat
Correct answer: D
Rationale: Clients prescribed trimethoprim-sulfamethoxazole (TMP-SMZ) should be educated about potential blood disorders associated with the medication. Early signs of these disorders include symptoms like sore throat, fever, and pallor. If the client experiences any of these symptoms, they should promptly notify their healthcare provider. Nausea, diarrhea, and headache are common side effects of TMP-SMZ that usually do not require immediate medical attention.
