HESI Pharmacology Quizlet
1. 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.
2. Which instruction should be included in the discharge teaching plan for a client who underwent cataract extraction today?
- A. Use a metal eye shield on the operative eye during the day.
- B. Administer eye ointment before applying eye drops.
- C. Sexual activities may be resumed after returning home.
- D. Light housekeeping is safe to do, but avoid heavy lifting.
Correct answer: D
Rationale: The correct instruction to include in the discharge teaching plan for a client who underwent cataract extraction is to advise them that light housekeeping is safe to do, but they should avoid heavy lifting. Heavy lifting can strain the surgical site and potentially lead to complications. Choice A is incorrect as a metal eye shield is usually recommended during sleep, not during the day. Choice B is incorrect because eye ointment should typically be administered after applying eye drops to prevent dilution of the medication. Choice C is incorrect as sexual activities should usually be avoided for a specific period post-surgery as advised by the healthcare provider.
3. A male client with bipolar disorder who began taking lithium carbonate five days ago is complaining of excessive thirst, and the RN finds him attempting to drink water from the bathroom sink faucet. Which intervention should the RN implement?
- A. Report the client’s serum lithium level to the healthcare provider (HCP).
- B. Encourage the client to suck on hard candy to relieve the symptoms.
- C. No action is needed since polydipsia is a common side effect.
- D. Tell the client that drinking from the faucet is not allowed.
Correct answer: B
Rationale: Encouraging the client to suck on hard candy is the appropriate intervention in this situation. Excessive thirst is a common side effect of lithium therapy. Sucking on hard candy can help alleviate the symptom without posing any harm. Reporting the client's serum lithium level to the healthcare provider (Choice A) is not necessary at this point as the symptom of excessive thirst is a known side effect and does not indicate toxicity. No action is needed (Choice C) is incorrect because addressing the client's distress is essential. Telling the client that drinking from the faucet is not allowed (Choice D) does not address the underlying issue of excessive thirst and may cause further distress to the client.
4. After each feeding, a 3-day-old newborn is spitting up large amounts of Enfamil® Newborn Formula, a nonfat cow's milk formula. The pediatric healthcare provider changes the neonate's formula to Similac® Soy Isomil® Formula, a soy protein isolate-based infant formula. What information should the LPN/LVN provide to the mother about the newly prescribed formula?
- A. The new formula is a coconut milk formula used with babies with impaired fat absorption.
- B. Enfamil® Formula is a demineralized whey formula that is needed with diarrhea.
- C. The new formula is a casein protein source that is low in phenylalanine.
- D. Similac® Soy Isomil® Formula is a soy-based formula that contains sucrose.
Correct answer: D
Rationale: The LPN/LVN should inform the mother that Similac® Soy Isomil® Formula is a soy-based formula containing sucrose. This formula is suitable for infants with cow's milk protein allergy or intolerance, which may be the reason for the newborn spitting up large amounts of the previous cow's milk formula.
5. After a client delivered vaginally 2 days ago, what information should you share with her if she wants to resume using her diaphragm for birth control?
- A. The diaphragm is the most effective form of contraception.
- B. The diaphragm must be refitted after childbirth.
- C. Vaseline lubricant should be used when inserting the diaphragm.
- D. The diaphragm should be inserted 2 to 4 hours before intercourse.
Correct answer: B
Rationale: After childbirth, the diaphragm must be refitted to ensure a proper fit and effectiveness. Changes in the body post-delivery can affect the fit of the diaphragm, making it necessary to get refitted. Choice A is incorrect because while the diaphragm can be effective, it is not the most effective form of contraception. Choice C is incorrect because oil-based lubricants like Vaseline can damage latex diaphragms. Choice D is incorrect because the diaphragm should be inserted no more than 2 hours before intercourse, not 2 to 4 hours.
