1. A client with hyperparathyroidism has a serum calcium level of 13 mg/dL. Which medication should be prepared to administer as prescribed to the client?
- A. Calcium chloride
- B. Calcium gluconate
- C. Calcitonin (Miacalcin)
- D. Large doses of vitamin D
Correct answer: C
Rationale: The normal serum calcium level ranges from 8.6 to 10.0 mg/dL. In hypercalcemia, as seen in this client, Calcitonin (Miacalcin) is used to decrease plasma calcium levels by inhibiting bone resorption. Calcium gluconate and calcium chloride are typically used for hypocalcemia, not hypercalcemia. Large doses of vitamin D should be avoided in hypercalcemia as they can exacerbate hypercalcemia by increasing calcium absorption from the intestines.
2. A postoperative client has received a dose of naloxone hydrochloride for respiratory depression shortly after transfer to the nursing unit from the postanesthesia care unit. After administration of the medication, the nurse checks the client for:
- A. Pupillary changes
- B. Scattered lung wheezes
- C. Sudden increase in pain
- D. Sudden episodes of diarrhea
Correct answer: C
Rationale: Naloxone hydrochloride is an antidote to opioids and may be administered to postoperative clients to address respiratory depression. This medication can also reverse the effects of analgesics, potentially leading to a sudden increase in pain. Therefore, the nurse must assess the client for any unexpected rise in pain levels after naloxone administration. Choices A, B, and D are incorrect because pupillary changes, scattered lung wheezes, and sudden episodes of diarrhea are not typically associated with naloxone administration for respiratory depression.
3. A client is to begin a 6-month course of therapy with isoniazid (INH). A nurse plans to teach the client to:
- A. Avoid drinking alcohol.
- B. Report yellow eyes or skin immediately.
- C. Avoid Swiss or aged cheeses.
- D. Avoid vitamin supplements during therapy.
Correct answer: B
Rationale: When a client is on isoniazid (INH) therapy, they should be instructed to report any signs of hepatitis, such as yellowing of the eyes or skin, immediately. Alcohol consumption should be avoided during INH therapy due to the risk of hepatotoxicity. Foods high in tyramine, such as Swiss or aged cheeses, should also be avoided to prevent adverse reactions. Additionally, while on INH therapy, it is essential to avoid vitamin supplements containing pyridoxine (vitamin B6) to prevent potential interactions.
4. Oxybutynin chloride (Ditropan XL) is prescribed for a client with neurogenic bladder. Which sign would indicate a possible toxic effect related to this medication?
- A. Pallor
- B. Drowsiness
- C. Bradycardia
- D. Restlessness
Correct answer: D
Rationale: Signs of toxicity related to oxybutynin chloride (Ditropan XL) include central nervous system excitation, such as nervousness, restlessness, hallucinations, and irritability. Other signs of toxicity may include hypotension or hypertension, confusion, tachycardia, a flushed or red face, and signs of respiratory depression. Restlessness is a sign of central nervous system excitation, which can indicate a possible toxic effect of this medication.
5. A client with hypertension is prescribed clonidine (Catapres) transdermal patch. Which statement by the client indicates an understanding of the medication?
- A. I should change the patch daily.
- B. I should remove the old patch before applying a new one.
- C. I should avoid alcohol consumption while using this patch.
- D. I should apply the patch to different sites each time.
Correct answer: B
Rationale: The correct answer is B. The client should remove the old clonidine (Catapres) patch before applying a new one to prevent overdose. The patch is typically changed every 7 days. Avoiding alcohol consumption is important as it can potentiate the sedative effects of clonidine. It is recommended to rotate application sites to prevent skin irritation and ensure optimal drug absorption.
